Widespread PHP Flaw May Cause Many Site Outages Today

mercredi 21 octobre 2026 à 17:26

Expect to see quite a few websites serving error pages today: Nearly 70 percent of websites need to update their core software to fix a pair of vulnerabilities that allow an attacker to seize full control over affected servers. Experts say there are working exploits for the flaws, and that these critical bugs are already being exploited in the wild.

The flaws at issue are present in PHP, the programming language that powers sites running on a large number of web publishing systems, including Drupal, Magento, Joomla and WordPress. Earlier today, PHP released an emergency security update to fix two critical bugs that can allow an attacker to execute code of their choosing on a vulnerable server.

Reuters reports that government websites in Europe and elsewhere went offline today after the PHP vulnerabilities were disclosed. Cloudflare said it has already detected some exploitation of the flaw, and that at 3:02 am (UTC) it implemented web application firewall rules to protect websites from attack traffic seeking to exploit the bugs, which could cause a denial of service condition, remote code execution, and data exposure.

OpenAI, which was involved in the vulnerability research and outreach, said “given the severity of these flaws and PHP’s widespread use, we consider this one of the most impactful security issues in recent memory.”

Censys, a company that tracks the technology used by Internet hosts, said a recent scan identified approximately 2.58 million Internet facing hosts and 54.9 million web properties running PHP.

Security experts at Wiz said every PHP version released in the last decade is affected by at least one of these vulnerabilities [full disclosure: Wiz is an advertiser on this blog].

“These findings rank among the most severe vulnerabilities discovered in PHP, and arguably in software history,” reads a blog post published today by a team of researchers at Wiz, which was one of several organizations credited with discovering the vulnerabilities. “The underlying flaws had been present for decades, but demonstrating their exploitability required an exceptionally complex chain of steps, at the edge of what human researchers could practically achieve. Frontier AI models substantially reduced that barrier, turning a longstanding flaw into an exploit.”

The Wiz researchers say it is likely the PHP vulnerabilities will be mass-exploited to install web-based backdoors or “web shells,” which give attackers a web-based panel that allows them to remotely control infected sites. Wiz said that prior to the PHP bugs being publicly disclosed, the company worked with the PHP team, Calif and OpenAI to measure the size of the problem and coordinate patch verification and disclosure.

The PHP zero-day vulnerabilities are being tracked by their CVE numbers, CVE-2026-109618 and CVE-2026-109619, and they affect all web servers running PHP 5.4 or later. The bugs are fixed in PHP 8.5.12, 8.4.27, 8.3.36, and 8.2.35.

According to Wiz, PHP is so deeply embedded in many web applications that we are likely to see organizations struggling to patch these vulnerabilities for some time to come, comparing this PHP vulnerability pair with the Log4Shell weakness that emerged in 2021 — a widespread, severe-as-it-gets security flaw in Log4j, a popular Java logging framework.

“A vulnerability in core PHP reaches far beyond a single application,” the Wiz researchers wrote. “PHP runs across clouds, hosting providers, content-delivery networks and millions of independently managed servers. Reducing exposure before the technical details became public required coordinated work across that entire ecosystem.”

The SANS Internet Storm Center is keeping an eye on major software platforms that are shipping updates to deal with these PHP flaws. For example, Ubuntu just released updated PHP packages. For a technical deep-dive on these vulnerabilities that tells the timeline of the discovery of these bugs in a comic book style, check out this post from Calif, another technology company credited with finding the PHP flaws.

This is a fast-moving story. Updates will be noted here with timestamps.

Update, 2:30 pm ET: Add figures from Censys and a link to Calif’s writeup.

Feds Suspect Ransom Negotiator Ran ShinyHunters Extortion Site

lundi 19 octobre 2026 à 15:48

U.S. federal investigators pursuing the ShinyHunters hacking group that recently stole highly sensitive data from the FBI have identified executives at two different ransomware negotiation firms who maintained unusually close relations with the extortion group, KrebsOnSecurity has learned. Sources close to the investigation say one of the executives in the United States even helped ShinyHunters operate a website that pressured victims into paying a ransom.

Hackers aligned with ShinyHunters have claimed credit for dozens of major data breaches since 2019, when the group was primarily operated by cybercriminals living in France. As those original members were arrested or jailed one by one, control over the ShinyHunters brand eventually passed to “Rey,” identified last year as a teenage hacker from Amman, Jordan. According to the FBI, ShinyHunters has extorted more than $70 million from victims so far this year.

In late September, ShinyHunters hacked the FBI recruitment website fbijobs.gov and taunted the agency by threatening to publish the stolen files, which reportedly included medical and psychological records, Social Security numbers and home addresses, and information about each employee’s unit and specialization.

The FBI jobs site hack has prompted the agency to move with uncommon speed to arrest, detain and question people who had any communications with Rey or other ShinyHunters suspects. Reuters reported on October 3 that Rey had been detained by Jordanian authorities and was cooperating with the FBI.

Rey was able to assume control over the hacking group because one of its alleged senior members had just been nabbed. On the evening of September 15, 2026, authorities in the Netherlands arrested convicted hacker and ShinyHunters suspect Pepijn van der Stap. Dutch police reportedly used flash-bang grenades in an effort to stun and apprehend Van der Stap as he was logged in to various online accounts.

According to a source close to the investigation, the authorities arrested Van der Stap while he was using his Signal instant messaging account, which allowed them to read recent communications with frequent contacts — including ransomware negotiators based in Canada and the United States.

Multiple sources with knowledge of the matter told KrebsOnSecurity that Van der Stap’s messages were the key to unraveling a murder-for-hire plot that emerged immediately following his arrest. The Dutch news outlet RTL reported last month the two murders were allegedly to be committed abroad, and that there are indications Van der Stap gave the order for the attacks (there is no indication those orders were ever carried out).

On October 9, KrebsOnSecurity broke the news that the FBI arrested a 54-year-old Canadian cybersecurity executive named Edward Dubrovsky in connection with the ShinyHunters investigation. Dubrovsky, who recently published a book on handling cyber extortion that recommended always engaging with the hackers, was charged with threatening to disclose stolen or hacked data and interfering with interstate commerce through extortion, according to court records. Politico reports prosecutors have asked that Dubrovsky remain in custody pending trial, and that records related to his case remain under seal.

A source close to the investigation told KrebsOnSecurity that Van der Stap’s Signal messages showed he had frequent conversations with Mr. Dubrovsky and with at least one executive at a large U.S.-based consulting firm, and that these executives often knew the details about new ShinyHunters victims before the victims themselves had even learned of the breach.

That source shared another potentially explosive finding by federal investigators: the Dutch hacker’s chats showed Mr. Dubrovsky knew ShinyHunters had stolen highly sensitive data from FBI servers, and that he never informed the bureau of the data breach prior to ShinyHunters threatening on Twitter/X to publish the agency’s deeply personal personnel files.

SHINYWIRE

KrebsOnSecurity has learned from two sources close to the ShinyHunters probe that FBI investigators believe at least one executive at a U.S.-based consulting firm played an active role in operating the now-defunct ShinyHunters victim extortion website “shinywire[.]com.” KrebsOnSecurity is not naming the U.S. company or the suspected executive(s) for now because they have not yet been charged with a crime, but it is a prestigious firm with more than 1,000 associates.

A section of the homepage for the now-defunct Shinywire website.

The Shinywire website was active from approximately May 3, 2026 until October 16 and had entries for nearly 100 organizations hacked by ShinyHunters. Each entry urged victims to engage with the cybercrime group and discuss terms for payment. The pages also included samples of stolen files and promised those files would be published online if the victim ignored their demands.

The following screenshot shows a cached portion of the Shinywire extortion page for Intuitive Surgical, an American medical technology company that was breached in March 2026 after an employee fell for a targeted phishing email.

Victim organizations that refused to engage or negotiate after seven days would find all of their stolen data published on the ShinyHunters victim shaming blog (a website that is only reachable via the anonymity network Tor).

In a story published October 15, The Globe and Mail wrote that a few months before Edward Dubrovsky was arrested by the FBI, the Canadian cybersecurity executive alleged in court documents he had become collateral damage in a campaign by a former business partner to “destroy” another industry executive.

The story noted that Dubrovsky filed the lawsuit in Ontario this year against Daniel Tobok, the former chief executive of Cypfer, a cybersecurity firm founded in Toronto with offices in the U.S., Britain, the Netherlands, the United Arab Emirates, and Mexico. The two first became business partners in 2017 and later developed Cypfer together, where Mr. Dubrovsky was a managing partner and chief operating officer. But by 2024, the two had a falling out, with Dubrovsky accusing Tobok of gradually excluding him from business matters and making “increasingly capricious business decisions.”

Mr. Tobok reportedly denied the allegations and filed a counterclaim, accusing Mr. Dubrovsky of accessing confidential information and unfairly competing with Cypfer through work at another firm called CyberSteward Inc. He also said Mr. Dubrovsky has misrepresented himself as a Cypfer founder, and is not a shareholder.

GHOSTBYTE

According to interviews with several former colleagues of Mr. Tobok, as far back as eight years ago he was known to ransomware purveyors by a particular nickname: Ghostbyte. In 2018, a Canadian company was hacked by Dharma, a prolific Russian-language ransomware affiliate program that first surfaced in 2016. The victim company told the Dharma ransomware representative they were leaning toward paying because some of the files were unrecoverable after being locked, but that they needed a better guarantee that Dharma would keep their word if paid.

A redacted copy of the Dharma rep’s reply is pictured below, and it shows the ransomware group urged the victim to contact a person at a Canadian IT firm that helps companies seeking such guarantees. The Dharma rep recommended the victim contact the email address ghostbyte@tutanota.com.

“If you want guarantees, you can write to the IT company,” the Dharma reply advised. “Take the phone and negotiate with them. This IT company often solves such problems in Canada. You can contact them and sign a contract for services. You’ll still have to pay.”

An email reply from the Dharma ransomware group to a victim, recommending they contact an email address that is connected to Mr. Tobok.

It’s unclear if Mr. Tobok ever used that Ghostbyte address offered by the Dharma representative, and he has not responded to multiple requests for comment. However, the breach tracking service Constella Intelligence finds an email address Mr. Tobok has frequently used — dtobok@me.com — is associated with two online accounts where the chosen username was “ghostbyte,” including a Snapchat account.

Incidentally, Constella also finds the Dharma rep’s email address luckygoodlucky@tuta.io is associated with a cryptocurrency address that processed 38 transactions totaling 43 bitcoin, ~$3.5 million at today’s value (the most recent transaction for this wallet is dated February 2019).

In a statement shared on October 14, Cypfer said the company’s business does not include making or facilitating ransomware payments, and that Cypfer learned of Dubrovsky’s arrest when the news first broke in the media.

“We had no prior knowledge of Mr. Dubrovsky’s arrest,” a spokesperson told KrebsOnSecurity via email. “CYPFER has not received any outreach from law enforcement and, to our knowledge, is not the target of any law enforcement investigation.”

The statement said CyberSteward and Cypfer are separate companies with no officers, directors or employees in common, and that Cypfer was recently acquired by the Apros Group, a holding company led by Jason Hogg, a former FBI special agent and former CEO of Aon Cyber Solutions Group. In 2020, Aon aquired Cytelligence, a security consulting firm where Mr. Tobok was founder and CEO and Mr. Dubrovsky was a managing partner.

CONFLICTING INTERESTS

It is not illegal in the United States to pay hackers for an encryption key to unlock servers infected with ransomware, or in exchange for a promise to delete any stolen files and refrain from publishing them online. While victim organizations can land in legal hot water if they pay a ransom to a group that is sanctioned by the U.S. Treasury Department, ShinyHunters is not among the ransomware groups currently sanctioned by the United States or by any other government.

Experts say ransomware victims are typically directed by their insurance provider to work with a specific incident response firm. But not all cyber forensics and breach response companies will agree to facilitate payments to ransomware groups on behalf of their clients. As a result, once victim firms make a decision to pay, the firms that eschew rewarding extortionists are invariably replaced by companies that have no such qualms.

In December 2024, ShinyHunters began extorting the education technology company PowerSchool, stealing private information on 62 million students and 9.5 million teachers in the U.S. and Canada. PowerSchool reportedly paid a $2.85 million ransom demand, and a “frequently asked questions” statement (PDF) about the breach says PowerSchool was assisted in that effort by CyberSteward (ShinyHunters affiliate Matthew Lane, 20, of Sterling, Mass., was sentenced in November 2025 to four years in prison for his admitted role in the PowerSchool hack).

But that ransom payment did not stop future extortion attempts using the same stolen data. By May 2025, individual school districts were reportedly receiving separate ransom demands using samples of the same stolen files. While nobody has alleged ShinyHunters was behind the second wave of extortion against PowerSchool users, the incident drives home the reality that there is no technical way to verify the threat actors have deleted the stolen data as promised, or prevent others from abusing the same records.

A number of leading cyber incident response firms, including Coveware and Unit 221B, have consistently warned victims against paying ShinyHunters, noting that “destroyed” victim data is often kept, resold or used to extort the company’s clients directly later on.

The FBI echoed those sentiments in an alert on May 15, 2026 advising victims against paying the ShinyHunters group. Meanwhile, ShinyHunters members have been harassing and threatening employees at Coveware and Unit 221B for offering this advice.

The following screenshots show just how annoyed the ShinyHunters leaders were with Coveware’s relentless advice against paying the group. The first image is from a conversation on May 6, 2026 that took place between the group’s main account on Telegram and a co-conspirator. In that chat, snippets of which were shared with KrebsOnSecurity by a trusted source, ShinyHunters complained that Coveware was harming the group’s payment rates.

“Go on my website, majority of those companies would’ve paid if it weren’t for Coveware giving them misinformation,” the ShinyHunters account wrote. “Someone (100% Coveware) is going out of their way to make sure i am not paid.”

In another conversation on April 11, 2026, the ShinyHunters Telegram account privately said they were trying to “eliminate the problem,” which they said was Coveware. Coveware declined to comment for this story.

“I’m sure the company will pay but in this specific case I am aware of Coveware and their involvement, and I’ve probably been not getting a lot of other negotiations mostly likely because Coveware keeps getting involved,” the ShinyHunters account bemoaned.

Mark Camillo is chief executive at CyberAcuView, an industry group founded in 2021 by a consortium of major cyber insurance carriers. Camillo said some firms charge a flat retainer fee, while those that specialize in helping companies negotiate a ransom payment tend to charge a percentage of the total ransom amount paid.

That latter dynamic, he said, is an inherent conflict of interest, as the negotiator has every incentive to make things more favorable to the attackers because they are financially incentivized to negotiate and pay out, and to not negotiate down on the price.

“It has come to the industry’s attention that many of the ransomware payers charge a percentage of the final payment which may or may not be disclosed,” Camillo said. “This makes no sense if they are also the negotiator. There needs to be more transparency in the process as no one in the ecosystem should be profiting purely on the size of the ransomware transaction or payment itself.”

Camillo said the firms doing this work would argue the fees are needed because there may be unexpectedly higher costs to secure larger quantities of cryptocurrency or more risk carrying the float, and because cryptocurrency exchanges may charge higher fees for high risk transactions.

“There definitely needs to be more visibility around the transaction and clarity on the increasing value of the crypto and the exchange’s percent in the transaction to get to the bottom of this and remove any misaligned incentives,” he said.

In recent months, the U.S. Department of Justice has prosecuted a number of ransomware negotiators alleged to have conspired with cybercriminals to defraud their clients. On October 7, the DOJ charged MonsterCloud CEO Zohar Pinhasi, 50, with wire fraud and conspiracy for allegedly charging customers to remediate ransomware attacks without paying the hackers. According to charging documents, Pinhasi secretly went behind his customers’ backs and paid hackers anyway, paying ransomware groups $8 million while charging customers $19 million.

In July, Angelo Martino, a 41-year-old ransomware negotiator from Land O’Lakes, Florida, was sentenced to 70 months in prison for conspiring with the Blackcat/ALPHV ransomware group to extort multiple victims. According to the DOJ, Martino was paid by BlackCat attackers to provide confidential information about the negotiating position and strategy of his employer’s clients and enable the ransomware actors to maximize the ransoms paid by the victims.

U.K. Sanctions Cryptomus for RU Money Laundering

mercredi 14 octobre 2026 à 16:22

The United Kingdom has issued economic sanctions against Cryptomus, a chameleonic cryptocurrency platform that experts say serves as a major conduit for payments related to ransomware, narcotics, darknet markets, fraud and cybercrime services that are helping Russia circumvent existing financial restrictions.

On October 8, the U.K. issued sanctions (PDF) against Cryptomus — previously known as Certa Payments and Xeltox Enterprises — for processing payments that benefit the Russian government and its financial institutions. The sanctions freeze any Cryptomus assets at U.K. banks, and bar British companies from offering it any business, virtual or otherwise. Also targeted in these sanctions were the virtual payment platforms VexPay, TokenSpot, and the Tsunami Payments service.

As explained in our December 2024 investigation, “How Cryptocurrency Turns to Cash in Russian Banks,” Cryptomus has been a key payment processor for dozens of Russian cryptocurrency exchanges and websites hawking cybercrime services. The company has changed its name several times since emerging in 2022, most recently to “Heleket” last year after Canada levied a record CAD $176 million fine against the platform for anti-money laundering violations.

The blockchain data-crunching firm Chainalysis said the U.K. sanctions target the broader infrastructure supporting Russia’s wartime economy.

“Cryptomus and Heleket have emerged as major payment hubs for illicit activity,” Chainalysis wrote in an October 8 blog post. “Together, these services received more illicit funds across tracked categories than the mixers in our dataset and the number of illicit counterparties surged to more than 900 in a single month in late 2025.”

The Cryptomus support bot on Telegram, responding on Oct. 8 to an inquiry by saying the platform was suddenly unable to process transactions.

In April 2026, the blockchain analysis firm TRM Labs found Cryptomus had processed more than $7 billion in transactions since its inception in 2022, including transactions associated with child sexual abuse material vendors, terrorist financing networks, and human trafficking operations.

TRM noted that Cryptomus’s transaction volume cratered after the platform instituted new “know your customer” or KYC rules, and that the cryptocurrency platform responded to the Canadian fines by launching Heleket as a parallel service that continued to offer no-KYC payment processing.

Richard Sanders is a blockchain analyst and investigator who spent months mapping out Cryptomus’s payment infrastructure and transacting with its customers. Sanders said the U.K. sanctions on Cryptomus are important because Canada’s sanctions against the platform were ultimately unenforceable and uncollectible.

“A fine doesn’t stop a cryptocurrency payment processor from processing payments,” Sanders wrote on LinkedIn. “Sanctions kill the operation. The distinction matters.”

As our 2024 investigation noted, Cryptomus shared a Vancouver address with dozens of other foreign currency dealers and money transfer businesses — none of which appeared to be physically located there. Following the CAD $176 million fine for alleged money laundering violations, Cryptomus appealed the penalty, launched Heleket as a parallel service, and kept on processing large volumes of sketchy transactions, Sanders said.

Sanders said the sanctions also are notable because they are the first known instance of a “Five Eyes” country (referring to the Australia, Canada, New Zealand, the U.K. and the U.S.) sanctioning a cryptocurrency operation incorporated in another Five Eyes jurisdiction.

Where do entities like Cryptomus and Heleket derive their authority to offer international financial services? The answer appears to involve fake financial institutions overseen by a phony regulatory body positioned in a country that is not widely recognized as a sovereign nation.

Our 2024 investigation found the sole shareholder of Cryptomus’s parent company Certa Payments was a 25-year-old Ukrainian woman who also headed several other firms, including the WS Management and Advisory Corporation, which bills itself as the regulatory body that exclusively oversees licenses for cryptocurrency, foreign exchange and online gaming businesses incorporated in the disputed region in northwest Africa known as the Western Sahara.

That entity’s website — crasadr.com — says it assists applicants with bank setup and formation, online gaming licenses, and the creation and licensing of foreign exchange brokers. One of Certa Payments’ former sites — certa[.]website — also shared a server with 12 other domains, including rasd-state[.]ws, a website for the Central Reserve Authority of the Western Sahara.

Microsoft Patches More Than 1,400 Security Flaws

mercredi 14 octobre 2026 à 01:24

Microsoft today issued updates to fix more than 1,400 security vulnerabilities in its Windows operating systems and other software. Today’s epic patch batch dwarfs September’s record of nearly 1,000 fixes, which was already about ten times the normal monthly patch load from Redmond.

Just one of the weaknesses patched this week is considered a “zero day,” or already exploited in the wild. CVE-2026-96951 is a security feature bypass in the Windows Shell that affects Windows 10 and 11 systems, as well as some Server versions.

Windows 10 users might be wondering if they can still expect security updates after this month. Microsoft had been slated to stop shipping updates for Windows 10 systems in October 2025, but ended up adding another year of free updates after considerable pushback. A few months ago, Microsoft quietly extended that support for another year (until October 2027).

At least 78 of the flaws fixed this month are rated “critical,” meaning they could be exploited with little or no action by the user, and most of those critical bugs allow an attacker to execute code of their choice on the vulnerable system.

While Microsoft said there are no signs anyone is exploiting it yet, a security feature bypass in the .NET Framework (CVE-2026-108398) was publicly disclosed prior to today, potentially giving attackers advance time to work out how to exploit the bug.

Satnam Narang at Tenable said the number of flaws fixed this month far surpasses the previous record-setting year 2020, when Microsoft patched 1,261 CVEs.

“We’ve now crossed the 4,000 CVE mark with two months left to go,” he said.

Microsoft credits large language models for the high volume of bug discovery, and presumably AI gets credit for many of the patches used to fix these flaw. Meanwhile, security experts have been warning that these unusually large patch volleys from Microsoft are placing extra strain on corporate security teams, which often have to test individual updates before deploying them across a network to ensure the fixes don’t cause problems for other software.

Tyler Reguly, associate director of security research and development at Fortra, notes that just 26 Microsoft vulnerabilities appeared in the “Known Exploited Vulnerabilities” (KEV) catalog maintained by the U.S. Cybersecurity & Infrastructure Security Agency (CISA) so far this year, and security teams would do well to prioritize patching those 26 vulnerabilities first.

“Security leaders should focus on exploitable risk, and ask whether their teams have the clarity, capacity and support to act,” Reguly said.

Which vulnerabilities deserve the most scrutiny in your organization? The folks at Cisco Talos have a useful roundup of the more noteworthy flaws that Microsoft fixed today, and of course the SANS Internet Storm Center has a reliable roundup that indexes vulnerabilities by severity, CVE number and affected software.

FBI Arrests Founder of Ransomware Negotiation Firm

samedi 10 octobre 2026 à 02:17

Agents with the Federal Bureau of Investigation (FBI) on Thursday arrested the co-founder of a Canadian cybersecurity firm in connection with an investigation into the ShinyHunters hacking group that recently relieved the FBI of sensitive data on thousands of agents, multiple sources tell KrebsOnSecurity.

The New York Times reported today that the FBI has arrested a Canadian man in Pennsylvania on suspicion of assisting ShinyHunters. The Times story did not identify the man, nor did a statement on Twitter/X about the arrest from FBI Director Kash Patel.

One source close to the investigation told KrebsOnSecurity the Canadian person arrested this week was visiting Pennsylvania for a cyber insurance conference, and that the suspect’s company specialized in handling ransomware negotiations with cybercrime groups. Another shared that control over the ShinyHunters investigation has been centralized at an FBI field office in Texas.

An online search reveals the Cyber Risk Summit was held at the Loews Philadelphia Hotel between Oct. 5 and Oct. 7. The conference had several sponsors, but according to the summit’s website its biggest sponsor was a Canadian security company called Cypfer.

According to LinkedIn, Cypher was co-founded by a Canadian man named Edward Dubrovsky, who is now associated with another Canadian security firm called CyberSteward. In a post to LinkedIn approximately one month ago, Dubrovsky said he had plans to attend the Cyber Risk Summit with the rest of the CyberSteward team.

Edward Dubrovsky’s LinkedIn profile.

“Looking forward to continuing conversations around strategy & compliant driven coercive (ransomware, extortion) advisory, negotiations and settlement services that are global and truly agnostic,” Dubrovsky wrote.

Federal court records show that on October 8, an Edward Dobrovsky (note the slight misspelling of the last name) was arrested in Pennsylvania on cyber extortion and conspiracy charges. Several of those documents — including the core complaint — are now sealed. But a handful of them were indexed at Courtlistener.com, including a summary of the complaint, which charges the defendant with “conspiracy to threaten to impair the confidentiality of information with the intent to extort money,” and “interference with commerce by threats.”

The inmate locator at the U.S. Bureau of Prisons website reports that a 54-year-old Edward Dubrovsky is currently being held at a federal facility in Philadelphia. But the court records indexed by CourtListener include a notice filed on October 9 that moved the case to the Eastern District of Texas, which sources say is now the epicenter of the FBI’s ShinyHunters investigation. The FBI declined to comment for this story.

Dubrovsky’s LinkedIn profile states he is the author of Cyber Extortion Strategic Response, a 252-page book that promises to “take readers beyond the ransom note and into the decisions that determine how an organization responds, recovers, and protects what matters.”

Edward Dubrovsky’s book, which centers on the intricacies of ransomware negotiations.

“At the heart of the book is a critical distinction: communicating with a criminal is not the same as negotiating a payment, and negotiating is not a commitment to pay,” reads an excerpt from the book’s listing on Amazon. “Engagement can serve other objectives, including testing claims, gathering information, creating time, and preserving options while the organization evaluates its next move.”

Mr. Dubrovsky could not be immediately reached for comment. KrebsOnSecurity also sought comment from the other co-founder of CyberSteward, and will update this post in the event they respond. The available court records in Dubrovsky’s case show that he does not currently have an attorney and has yet to be appointed a public defender by the courts.

ShinyHunters typically uses phishing and stolen credentials to siphon data from corporate accounts at software-as-a-service companies, and then threatens to publish the stolen data online unless a ransom demand is paid. According to the FBI, the group has extorted more than $70 million from victims so far this year.

Sources tell KrebsOnSecurity the FBI has been poring over devices that were seized last month when the Dutch police arrested the convicted cybercriminal Pepijn van der Stap in connection with the ShinyHunters investigation, and that charges against principals at other companies that specialize in ransomware negotiation may be forthcoming.

Immediately after Van der Stap’s arrest, another member of ShinyHunters named “Rey” assumed control over the group and began taunting the FBI over data the group stole from the agency’s online recruitment portal, which included each’s person’s unit and specialization, as well as medical and psychiatric records.

Last week, Reuters reported that Rey — identified as a teenager named Saif Al-din Khader — had been detained and was cooperating with FBI investigators. On October 7, we detailed how Rey allegedly sought to extort a navigation and digital aviation unit recently spun off from Boeing just prior to his detention by Jordanian authorities.
