Happy 13th Birthday, KrebsOnSecurity!

jeudi 29 décembre 2022 à 23:35

KrebsOnSecurity turns 13 years old today. That’s a crazy long time for an independent media outlet these days, but then again I’m bound to keep doing this as long as they keep letting me. Heck, I’ve been doing this so long I briefly forgot which birthday this was!

Thanks to your readership and support, I was able to spend more time in 2022 on some deep, meaty investigative stories — the really satisfying kind with the potential to affect positive change. Some of that work is highlighted in the 2022 Year in Review review below.

Until recently, I was fairly active on Twitter, regularly tweeting to more than 350,000 followers about important security news and stories here. For a variety of reasons, I will no longer be sharing these updates on Twitter. I seem to be doing most of that activity now on Mastodon, which appears to have absorbed most of the infosec refugees from Twitter, and in any case is proving to be a far more useful, civil and constructive place to post such things. I will also continue to post on LinkedIn about new stories in 2023.

Here’s a look at some of the more notable cybercrime stories from the past year, as covered by KrebsOnSecurity and elsewhere. Several strong themes emerged from 2022’s crop of breaches, including the targeting or impersonating of employees to gain access to internal company tools; multiple intrusions at the same victim company; and less-than-forthcoming statements from victim firms about what actually transpired.

JANUARY

You just knew 2022 was going to be The Year of Crypto Grift when two of the world’s most popular antivirus makers — Norton and Avira — kicked things off by installing cryptocurrency mining programs on customer computers. This bold about-face dumbfounded many longtime Norton users because antivirus firms had spent years broadly classifying all cryptomining programs as malware.

Suddenly, hundreds of millions of users — many of them old enough to have bought antivirus from Peter Norton himself back in the day — were being encouraged to start caring about and investing in crypto. Big Yellow and Avira weren’t the only established brands cashing in on crypto hype as a way to appeal to a broader audience: The venerable electronics retailer RadioShack wasted no time in announcing plans to launch a cryptocurrency exchange.

By the second week of January, Russia had amassed more than 100,000 troops along its southern border with Ukraine. The Kremlin breaks with all tradition and announces that — at the request of the United States — it has arrested 14 people suspected of working for REvil, one of the more ruthless and profitable Russian ransomware groups.

Security and Russia experts dismiss the low-level arrests as a kind of “ransomware diplomacy,” a signal to the United States that if it doesn’t enact severe sanctions against Russia for invading Ukraine, Russia will continue to cooperate on ransomware investigations.

The Jan. 19th story IRS Will Soon Require Selfies For Online Access goes immediately viral for pointing out something that apparently nobody has noticed on the U.S. Internal Revenue Service website for months: Anyone seeking to create an account to view their tax records online would soon be required to provide biometric data to a private company in Virginia — ID.me.

Facing a backlash from lawmakers and the public, the IRS soon reverses course, saying video selfies will be optional and that any biometric data collected will be destroyed after verification.

FEBRUARY

Super Bowl Sunday watchers are treated to no fewer than a half-dozen commercials for cryptocurrency investing. Matt Damon sells his soul to Crypto.com, telling viewers that “fortune favors the brave” — basically, “only cowards would fail to buy cryptocurrency at this point.” Meanwhile, Crypto.com is trying to put space between it and recent headlines that a breach led to $30 million being stolen from hundreds of customer accounts. A single bitcoin is trading at around $45,000.

Larry David, the comedian who brought us years of awkward hilarity with hits like Seinfeld and Curb Your Enthusiasm, plays the part of the “doofus, crypto skeptic” in a lengthy Super Bowl ad for FTX, a cryptocurrency exchange then valued at over $20 billion that is pitched as a “safe and easy way to get into crypto.” [Last month, FTX imploded and filed for bankruptcy; the company’s founder now faces civil and criminal charges from three different U.S. agencies].

On Feb. 24, Russia invades Ukraine, and fault lines quickly begin to appear in the cybercrime underground. Cybercriminal syndicates that previously straddled Russia and Ukraine with ease are forced to reevaluate many comrades who are suddenly working for The Other Side.

Many cybercriminals who operated with impunity from Russia and Ukraine prior to the war chose to flee those countries following the invasion, presenting international law enforcement agencies with rare opportunities to catch most-wanted cybercrooks. One of those is Mark Sokolovsky, a 26-year-old Ukrainian man who operated the popular “Raccoon” malware-as-a-service offering; Sokolovsky was busted in March after fleeing Ukraine’s mandatory military service orders.

Also nabbed on the lam is Vyacheslav “Tank” Penchukov, a senior Ukrainian member of a transnational cybercrime group that stole tens of millions of dollars over nearly a decade from countless hacked businesses. Penchukov was arrested after leaving Ukraine to meet up with his wife in Switzerland.

Ransomware group Conti chimes in shortly after the invasion, vowing to attack anyone who tries to stand in Mother Russia’s way. Within hours of that declaration several years worth of internal chat logs stolen from Conti were leaked online. The candid employee conversations provide a rare glimpse into the challenges of running a sprawling criminal enterprise with more than 100 salaried employees. The records also reveal how Conti dealt with its own internal breaches and attacks from private security firms and foreign governments.

Faced with an increasing brain drain of smart people fleeing the country, Russia floats a new strategy to address a worsening shortage of qualified information technology experts: Forcing tech-savvy people within the nation’s prison population to perform low-cost IT work for domestic companies.

Chipmaker NVIDIA says a cyberattack led to theft of information on more than 71,000 employees. Credit for that intrusion is quickly claimed by LAPSUS$, a group of 14-18 year-old cyber hooligans mostly from the United Kingdom who specialized in low-tech but highly successful methods of breaking into companies: Targeting employees directly over their mobile phones.

LAPSUS$ soon employs these skills to successfully siphon source code and other data from some of the world’s biggest technology firms, including Microsoft, Okta, Samsung, T-Mobile and Uber, among many others.

MARCH

We learn that criminal hackers are compromising email accounts and websites for police departments worldwide, so that they can impersonate police and send legal requests to obtain sensitive customer data from mobile providers, ISPs and social media companies. That story prompts revelations that several companies — including Apple, Discord and Meta/Facebook — have complied with the fake requests, and draws the attention of Congress to the problem.

APRIL

It emerges that email marketing giant Mailchimp got hacked. The unknown intruders gained access to internal Mailchimp tools and customer data by social engineering employees at the company, and then started sending targeted phishing attacks to owners of Trezor hardware cryptocurrency wallets.

The FBI warns about a massive surge in victims from “pig butchering” scams, in which flirtatious strangers online lure people into investing in cryptocurrency scams. Investigative reports reveal pig butchering’s link to organized crime gangs in Asia that attract young job seekers with the promise of customer service jobs. Instead, those who show up at the appointed time and place are kidnapped, trafficked across the border into neighboring countries like Cambodia, and pressed into a life of indentured servitude scamming others online.

MAY

KrebsOnSecurity reports that hackers who specialize in filing fake police requests for subscriber data gained access to a U.S. Drug Enforcement Administration (DEA) portal that taps into 16 different federal law enforcement databases.

The government of Costa Rica is forced to declare a state of emergency after a ransomware attack by Conti cripples government systems. Conti  publishes nearly 700 GB worth of government records after the country’s leaders decline to pay a $20 million ransom demand.

JUNE

KrebsOnSecurity identifies Russian national Denis Emelyantsev as the likely owner of the RSOCKS botnet, a collection of millions of hacked devices that were sold as “proxies” to cybercriminals looking for ways to route their malicious traffic through someone else’s computer. Emelyantsev was arrested that same month at a resort in Bulgaria, where he requested and was granted extradition to the United States —  reportedly telling the judge, “America is looking for me because I have enormous information and they need it.”

JULY

Big-three consumer credit bureau Experian comes under scrutiny after KrebsOnSecurity reveals identity thieves are reliably seizing control over consumer credit files by simply re-registering using the target’s personal information and an email address tied to the crooks. Two months later, Experian would be hit with a class-action lawsuit over these security and privacy failures.

Twitter acknowledges that it was relieved of phone numbers and email addresses for 5.4 million users. The security weakness that allowed the data to be collected was patched in January 2022.

AUGUST

Messaging behemoth Twilio confirms that data on 125 customers was accessed by intruders, who tricked employees into handing over their login credentials by posing as employees of the company’s IT department.

Among the Twilio customers targeted was encrypted messaging service Signal, which relied on Twilio to provide phone number verification services. Signal said that with their access to Twilio’s internal tools, the attackers were able to re-register those users’ phone numbers to another device.

Food delivery service DoorDash discloses that a “sophisticated phishing attack” on a third-party vendor allowed attackers to gain access to some of DoorDash’s internal company tools. Thanks to data left exposed online by the intruders, it becomes clear that DoorDash was victimized by the same group that snookered employees at Twilio, Mailchimp, CloudFlare, and dozens of other major companies throughout 2022.

Mailchimp discloses another intrusion involving targeted phishing attacks against employees, wherein hackers stole data on more than 200 Mailchimp customers. Web hosting giant DigitalOcean discloses it was one of the victims, and that the intruders used their access to send password reset emails to a number of DigitalOcean customers involved in cryptocurrency and blockchain technologies. DigitalOcean severs ties with Mailchimp after that incident, which briefly prevented the hosting firm from communicating with its customers or processing password reset requests.

Password manager service LastPass discloses that its software development environment was breached, and that intruders made off with source code and some proprietary LastPass data. LastPass emphasizes the intruders weren’t able to access any customer data or encrypted password vaults, and that “there is no evidence of any threat actor activity beyond the established timeline,” and “no evidence that this incident involved any access to customer data or encrypted password vaults.”

SEPTEMBER

Uber discloses another breach, forcing the company to take several of its internal communications and engineering systems offline as it investigates. The intrusion only comes to light when the hacker uses the company’s internal Slack channel to boast about their access, listing several internal databases they claimed had been compromised. The intruder told The New York Times they got in by sending a text message to an employee while posing as an employee from Uber’s IT department. Uber blames LAPSUS$ for the intrusion.

Australian telecommunications giant Optus suffers a data breach involving nearly 10 million customers, including passport or license numbers on almost three million people. The incident dominates headlines and politics in Australia for weeks, as the hacker demands a million dollars in cryptocurrency not to publish the information online. Optus’s CEO calls the intrusion a “sophisticated attack,” but interviews with the hacker reveal they simply enumerated and scraped the data from the Optus website without authentication. After briefly posting 10,000 records from the intrusion, the hacker announces they made a mistake, and deletes the auction.

OCTOBER

A report commissioned by Sen. Elizabeth Warren (D-Mass.) reveals that most big U.S. banks are stiffing account takeover victims. Even though U.S. financial institutions are legally obligated to reverse any unauthorized transactions as long as the victim reports the fraud in a timely manner, the report cited figures showing that four of the nation’s largest banks collectively reimbursed only 47 percent of the dollar amount of claims they received.

Joe Sullivan, the former chief security officer for Uber, is found guilty of two felonies after a four-week trial. In 2016, while the U.S. Federal Trade Commission was already investigating a 2014 breach at Uber, another security breach affected 57 million Uber account holders and drivers. The intruders demand $100,000, but Sullivan and his team paid the ransom under the company’s bug bounty program, made the hackers sign a non-disclosure agreement, and concealed the incident from users and investors. The two hackers involved pleaded guilty in 2019; by this time, it has become a nearly everyday occurrence for victim companies to pay to keep a ransomware attack quiet.

NOVEMBER

A ransomware group with ties to REvil begins publishing names, birth dates, passport numbers and information on medical claims on nearly 10 million current and former customers of Australian health insurer Medibank. The data is published after Medibank reportedly declines to pay a US$10 million ransom demand.

DECEMBER

KrebsOnSecurity breaks the news that InfraGard, a program run by the U.S. Federal Bureau of Investigation (FBI) to build cyber and physical threat information sharing partnerships with the private sector, saw its database of contact information on more than 80,000 members put up for sale on an English-language cybercrime forum. Meanwhile, the hackers responsible were communicating directly with members through the InfraGard portal online — using a new account under the assumed identity of a financial industry CEO that was vetted by the FBI itself.

A cybercriminal starts selling account data scraped from 400 million Twitter users, including email addresses and in many cases phone numbers. The seller claims their data was scraped in late December 2021 using the same vulnerability that Twitter patched in January 2022, and that led Twitter to acknowledge the data scraping of 5.4 million user accounts earlier this year. Twitter no longer has a press office, and the company’s Chief Twit has remained silent about the 400 million claim so far, despite many indications that the data is legitimate.

Two days before Christmas, LastPass posted an update on its investigation into the August data breach, saying the intruder was able to use data stolen in the August breach to come back and copy a backup of customer vault data from the encrypted storage container. LastPass’s lackadaisical disclosure timeline and failure to answer follow-up questions has done little to assuage the fears of many users, leaving Wired.com to recommend users abandon the platform in favor of the password managers 1Password and Bitwarden.

Also two days before Christmas, KrebsOnSecurity notifies Experian that anyone can bypass security questions in their application for a free credit report, meaning identity thieves can access your full credit file with just your name, address, date of birth and Social Security number. Unfortunately, this static data on most Americans has been for sale in the cybercrime underground for years. Experian has yet to say whether it has fixed the problem, but expect to see a full report about this early in the New Year.

The Equifax Breach Settlement Offer is Real, For Now

mardi 20 décembre 2022 à 21:08

Millions of people likely just received an email or snail mail notice saying they’re eligible to claim a class action payment in connection with the 2017 megabreach at consumer credit bureau Equifax. Given the high volume of reader inquiries about this, it seemed worth pointing out that while this particular offer is legit (if paltry), scammers are likely to soon capitalize on public attention to the settlement money.

One reader’s copy of their Equifax Breach Settlement letter. They received a check for $6.97.

In 2017, Equifax disclosed a massive, extended data breach that led to the theft of Social Security Numbers, dates of birth, addresses and other personal information on nearly 150 million people. Following a public breach response perhaps best described as a giant dumpster fire, the big-three consumer credit reporting bureau was quickly hit with nearly two dozen class-action lawsuits.

In exchange for resolving all outstanding class action claims against it, Equifax in 2019 agreed to a settlement that includes up to $425 million to help people affected by the breach.

Affected consumers were eligible to apply for at least three years of credit monitoring via all three major bureaus simultaneously, including Equifax, Experian and Trans Union. Or, if you didn’t want to take advantage of the credit monitoring offers, you could opt for a cash payment of up to $125.

The settlement also offered reimbursement for the time you may have spent remedying identity theft or misuse of your personal information caused by the breach, or purchasing credit monitoring or credit reports. This was capped at 20 total hours at $25 per hour ($500), with total cash reimbursement payments not to exceed $20,000 per consumer.

Those who did file a claim probably started receiving emails or other communications earlier this year from the Equifax Breach Settlement Fund, which has been messaging class participants about methods of collecting their payments.

How much each recipient receives appears to vary quite a bit, but probably most people will have earned a payment on the smaller end of that $125 scale — like less than $10. Those who received higher amounts likely spent more time documenting actual losses and/or explaining how the breach affected them personally.

So far this week, KrebsOnSecurity has received at least 20 messages from readers seeking more information about these notices. Some readers shared copies of letters they got in the mail along with a paper check from the Equifax Breach Settlement Fund (see screenshot above).

Others said they got emails from the Equifax Breach Settlement domain that looked like an animated greeting card offering instructions on how to redeem a virtual prepaid card.

If you received one of these settlement emails and are wary about clicking the included links (good for you, by the way), copy the redemption code and paste it into the search box at myprepaidcenter.com/redeem. Successfully completing the card application requires accepting a prepaid MasterCard agreement (PDF).

The website for the settlement — equifaxbreachsettlement.com — also includes a lookup tool that lets visitors check whether they were affected by the breach; it requires your last name and the last six digits of your Social Security Number.

In February 2020, the U.S. Justice Department indicted four Chinese officers of the People’s Liberation Army (PLA) for perpetrating the 2017 Equifax hack. DOJ officials said the four men were responsible for carrying out the largest theft of sensitive personal information by state-sponsored hackers ever recorded.

Equifax surpassed Wall Street’s expectations in its most recently quarterly earnings: The company reported revenues of $1.24 billion for the quarter ending September 2022.

Of course, most of those earnings come from Equifax’s continued legal ability to buy and sell eye-popping amounts of financial and personal data on U.S. consumers. As one of the three major credit bureaus, Equifax collects and packages information about your credit, salary, and employment history. It tracks how many credit cards you have, how much money you owe, and how you pay your bills. Each company creates a credit report about you, and then sells this report to businesses who are deciding whether to give you credit.

Americans currently have no legal right to opt out of this data collection and trade. But you can and also should and freeze your credit, which by the way can make your credit profile less profitable for companies like Equifax — because they make money every time some potential creditor wants a peek inside your financial life. Also, it’s probably a good idea to freeze the credit of your children and/or dependents as well. It’s free on both counts.

Hacked Ring Cams Used to Record Swatting Victims

mardi 20 décembre 2022 à 02:24

Two U.S. men have been charged with hacking into the Ring home security cameras of a dozen random people and then “swatting” them — falsely reporting a violent incident at the target’s address to trick local police into responding with force. Prosecutors say the duo used the compromised Ring devices to stream live video footage on social media of police raiding their targets’ homes, and to taunt authorities when they arrived.

Prosecutors in Los Angeles allege 20-year-old James Thomas Andrew McCarty, a.k.a. “Aspertaine,” of Charlotte, N.C., and Kya Christian Nelson, a.k.a. “ChumLul,” 22, of Racine, Wisc., conspired to hack into Yahoo email accounts belonging to victims in the United States. From there, the two allegedly would check how many of those Yahoo accounts were associated with Ring accounts, and then target people who used the same password for both accounts.

An indictment unsealed this week says that in the span of just one week in November 2020, McCarty and Nelson identified and swatted at least a dozen different victims across the country.

“The defendants then allegedly accessed without authorization the victims’ Ring devices and transmitted the audio and video from those devices on social media during the police response,” reads a statement from Martin Estrada, the U.S. Attorney for the Central District of California. “They also allegedly verbally taunted responding police officers and victims through the Ring devices during several of the incidents.”

James Thomas Andrew McCarty.

The indictment charges that McCarty continued his swatting spree in 2021 from his hometown in Kayenta, Ariz., where he called in bomb threats or phony hostage situations on more than two dozen occasions.

The Telegram and Discord aliases allegedly used by McCarty — “Aspertaine” and “Couch,” among others — correspond to an identity that was active in certain channels dedicated to SIM-swapping, a crime that involves stealing wireless phone numbers and hijacking the online financial and social media accounts tied to those numbers.

Aspertaine bragged on Discord that he’d amassed more than $330,000 in virtual currency. On Telegram, the Aspertaine/Couch alias frequented several popular SIM-swapping channels, where they initially were active as a “holder” — a low-level but key SIM-swapping group member who agrees to hold stolen cryptocurrency after an account takeover is completed. Aspertaine later claimed more direct involvement in individual SIM-swapping attacks.

In September, KrebsOnSecurity broke the news about a wide-ranging federal investigation into “violence-as-a-service” offerings on Telegram and other social media networks, wherein people can settle scores by hiring total strangers to carry out physical attacks such as brickings, shootings, and firebombings at a target’s address.

The story observed that SIM swappers were especially enamored of these “IRL” or “In Real Life” violence services, which they frequently used to target one another in response to disagreements over how stolen money should be divided amongst themselves. And a number of Aspertaine’s peers on these SIM-swapping channels claimed they’d been ripped off after Aspertaine took more than a fair share from co-conspirators.

On April 30, 2022, a member of a popular SIM-swapping group on Telegram who was slighted by Aspertaine put out the word that he was looking for some physical violence to be visited on McCarty’s address in North Carolina. “Anyone live near here and wants to [do] a job for me,” the job ad with McCarty’s home address read. “Jobs range from $1k-$50k. Payment in BTC [bitcoin].” It’s unclear if anyone responded to that job offer.

In May 2021, KrebsOnSecurity published The Wages of Password ReUse: Your Money or Your Life, which observed that when normal computer users fall into the nasty habit of recycling passwords, the result is most often some type of financial loss. Whereas, when cybercriminals reuse passwords, it often costs them their freedom.

But perhaps that story should be updated, because it’s now clear that password reuse can also put you in mortal danger. Swatting attacks are dangerous, expensive hoaxes that sometimes end in tragedy.

In June 2021, an 18-year-old serial swatter from Tennessee was sentenced to five years in prison for his role in a fraudulent swatting attack that led to the death of a 60-year-old man.

In 2019, prosecutors handed down a 20-year sentence to Tyler Barriss, a then 26-year-old serial swatter from California who admitted making a phony emergency call to police in late 2017 that led to the shooting death of an innocent Kansas man.

McCarty was arrested last week in Arizona, and charged with conspiracy to intentionally access computers without authorization. Prosecutors said Nelson is currently incarcerated in Kentucky in connection with unrelated investigation.

If convicted on the conspiracy charge, both defendants would face a statutory maximum penalty of five years in federal prison. The charge of intentionally accessing without authorization a computer carries a maximum possible sentence of five years. A conviction on the additional charge against Nelson — aggravated identity theft — carries a mandatory two-year consecutive sentence.

Six Charged in Mass Takedown of DDoS-for-Hire Sites

mercredi 14 décembre 2022 à 20:58

The U.S. Department of Justice (DOJ) today seized four-dozen domains that sold “booter” or “stresser” services — businesses that make it easy and cheap for even non-technical users to launch powerful Distributed Denial of Service (DDoS) attacks designed knock targets offline. The DOJ also charged six U.S. men with computer crimes related to their alleged ownership of the popular DDoS-for-hire services.

The booter service OrphicSecurityTeam[.]com was one of the 48 DDoS-for-hire domains seized by the Justice Department this week.

The DOJ said the 48 domains it seized helped paying customers launch millions of digital sieges capable of knocking Web sites and even entire network providers offline.

Booter services are advertised through a variety of methods, including Dark Web forums, chat platforms and even youtube.com. They accept payment via PayPal, Google Wallet, and/or cryptocurrencies, and subscriptions can range in price from just a few dollars to several hundred per month. The services are generally priced according to the volume of traffic to be hurled at the target, the duration of each attack, and the number of concurrent attacks allowed.

Prosecutors in Los Angeles say the booter sites supremesecurityteam[.]com and royalstresser[.]com were the brainchild of Jeremiah Sam Evans Miller, a.k.a. “John the Dev,” a 23-year-old from San Antonio, Texas. Miller was charged this week with conspiracy and violations of the Computer Fraud and Abuse Act (CFAA). The complaint against Miller alleges Royalstresser launched nearly 200,000 DDoS attacks between November 2021 and February 2022.

Defendant Angel Manuel Colon Jr., a.k.a Anonghost720 and Anonghost1337, is a 37-year-old from Belleview, Fla. Colon is suspected of running the booter service securityteam[.]io. He was also charged with conspiracy and CFAA violations. The feds say the SecurityTeam stresser service conducted 1.3 million attacks between 2018 and 2022, and attracted some 50,000 registered users.

Charged with conspiracy were Corey Anthony Palmer, 22, of Lauderhill, Fla, for his alleged ownership of booter[.]sx; and Shamar Shattock, 19, of Margate, Fla., for allegedly operating the booter service astrostress[.]com, which had more than 30,000 users and blasted out some 700,000 attacks.

Two other alleged booter site operators were charged in Alaska. John M. Dobbs, 32, of Honolulu, HI is charged with aiding and abetting violations of the CFAA related to the operation of IPStresser[.]com, which he allegedly ran for nearly 13 years until last month. During that time, IPstresser launched approximately 30 million DDoS attacks and garnered more than two million registered users.

Joshua Laing, 32, of Liverpool, NY, also was charged with CFAA infractions tied to his alleged ownership of the booter service TrueSecurityServices[.]io, which prosecutors say had 18,000 users and conducted over 1.2 million attacks between 2018 and 2022.

Purveyors of stressers and booters claim they are not responsible for how customers use their services, and that they aren’t breaking the law because — like most security tools — stresser services can be used for good or bad purposes. For example, all of the above-mentioned booter sites contained wordy “terms of use” agreements that required customers to agree they will only stress-test their own networks — and that they won’t use the service to attack others.

But the DOJ says these disclaimers usually ignore the fact that most booter services are heavily reliant on constantly scanning the Internet to commandeer misconfigured devices that are critical for maximizing the size and impact of DDoS attacks.

“None of these sites ever required the FBI to confirm that it owned, operated, or had any property right to the computer that the FBI attacked during its testing (as would be appropriate if the attacks were for a legitimate or authorized purpose),” reads an affidavit (PDF) filed by Elliott Peterson, a special agent in the FBI’s Anchorage field office.

“Additionally, analysis of data related to the FBI-initiated attacks revealed that the attacks launched by the SUBJECT DOMAINS involved the extensive misuse of third-party services,” Peterson continued. “Specifically, all of the tested services offered ‘amplification’ attacks, where the attack traffic is amplified through unwitting third-party servers in order to increase the overall attack size, and to shift the financial burden of generating and transmitting all of that data away from the booter site administrator(s) and onto third parties.”

According to U.S. federal prosecutors, the use of booter and stresser services to conduct attacks is punishable under both wire fraud laws and the Computer Fraud and Abuse Act (18 U.S.C. § 1030), and may result in arrest and prosecution, the seizure of computers or other electronics, as well as prison sentences and a penalty or fine.

The charges unsealed today stemmed from investigations launched by the FBI’s field offices in Los Angeles and Alaska, which spent months purchasing and testing attack services offered by the booter sites.

A similar investigation initiating from the FBI’s Alaska field office in 2018 culminated in a takedown and arrest operation that targeted 15 DDoS-for-hire sites, as well as three booter store defendants who later pleaded guilty.

The Justice Department says its trying to impress upon people that even buying attacks from DDoS-for-hire services can land Internet users in legal jeopardy.

“Whether a criminal launches an attack independently or pays a skilled contractor to carry one out, the FBI will work with victims and use the considerable tools at our disposal to identify the person or group responsible,” said Donald Alway, the assistant director in charge of the FBI’s Los Angeles field office.

The United Kingdom, which has been battling its fair share of domestic booter bosses, in 2020 started running online ads aimed at young people who search the Web for booter services.

And in Europe, prosecutors have even gone after booter customers.

Here is the full list of booter site domains seized (or in the process of being seized) by the DOJ:

Microsoft Patch Tuesday, December 2022 Edition

mercredi 14 décembre 2022 à 18:01

Microsoft has released its final monthly batch of security updates for 2022, fixing more than four dozen security holes in its various Windows operating systems and related software. The most pressing patches include a zero-day in a Windows feature that tries to flag malicious files from the Web, a critical bug in PowerShell, and a dangerous flaw in Windows 11 systems that was detailed publicly prior to this week’s Patch Tuesday.

The security updates include patches for Azure, Microsoft Edge, Office, SharePoint Server, SysInternals, and the .NET framework. Six of the update bundles earned Microsoft’s most dire “critical” rating, meaning they fix vulnerabilities that malware or malcontents can use to remotely commandeer an unpatched Windows system — with little to no interaction on the part of the user.

The bug already seeing exploitation is CVE-2022-44698, which allows attackers to bypass the Windows SmartScreen security feature. The vulnerability allows attackers to craft documents that won’t get tagged with Microsoft’s “Mark of the Web,” despite being downloaded from untrusted sites.

“This means no Protected View for Microsoft Office documents, making it easier to get users to do sketchy things like execute malicious macros,
said Greg Wiseman, product manager at security firm Rapid7. This is the second Mark of the Web flaw Microsoft has patched in as many months; both were first publicly detailed over the past two months on Twitter by security researcher Will Dormann.

Publicly disclosed (but not actively exploited for now) is CVE-2022-44710, which is an elevation of privilege flaw in the DirectX graphics component of Windows 11.

Another notable critical bug is CVE-2022-41076, a remote code execution flaw in PowerShell — a key component of Windows that makes it easier to automate system tasks and configurations.

Kevin Breen at Immersive Labs said while Microsoft doesn’t share much detail about CVE-2022-41076 apart from the designation ‘Exploitation More Likely,’ they also note that successful exploitation requires an attacker to take additional actions to prepare the target environment.

“What actions are required is not clear; however, we do know that exploitation requires an authenticated user level of access,” Breen said. “This combination suggests that the exploit requires a social engineering element, and would likely be seen in initial infections using attacks like MalDocs or LNK files.”

Speaking of malicious documents, Trend Micro’s Zero Day Initiative highlights CVE-2022-44713, a spoofing vulnerability in Outlook for Mac.

“We don’t often highlight spoofing bugs, but anytime you’re dealing with a spoofing bug in an e-mail client, you should take notice,” ZDI’s Dustin Childs wrote. “This vulnerability could allow an attacker to appear as a trusted user when they should not be. Now combine this with the SmartScreen Mark of the Web bypass and it’s not hard to come up with a scenario where you receive an e-mail that appears to be from your boss with an attachment entitled “Executive_Compensation.xlsx”. There aren’t many who wouldn’t open that file in that scenario.”

Microsoft also released guidance on reports that certain software drivers certified by Microsoft’s Windows Hardware Developer Program were being used maliciously in post-exploitation activity.

Three different companies reported evidence that malicious hackers were using these signed malicious driver files to lay the groundwork for ransomware deployment inside victim organizations. One of those companies, Sophos, published a blog post Tuesday detailing how the activity was tied to the Russian ransomware group Cuba, which has extorted an estimated $60 million from victims since 2019.

Of course, not all scary and pressing security threats are Microsoft-based. Also on Tuesday, Apple released a bevy of security updates to iOS, iPadOS, macOS, tvOS and Safari, including  a patch for a newly discovered zero-day vulnerability that could lead to remote code execution.

Anyone responsible for maintaining Fortinet or Citrix remote access products probably needs to update, as both are dealing with active attacks on just-patched flaws.
