A Ukrainian lawyer who wound up coding malware for the Conti ransomware gang has been sentenced to four years in a US prison. Oleksii Oleksiyovych Lytvynenko, 44, pleaded guilty in June to conspiracy to commit wire fraud over his role in Conti, the Russia-linked ransomware operation associated with more than 1,000 victims and at least $150 million in ransom payments. Lytvynenko took an unusual route into the ransomware business. The Ukrainian national, who later lived in Cork, Ireland, trained as a lawyer before joining Conti as an intruder and developer. According to his plea agreement [PDF], Lytvynenko operated under the handle "henry" and joined a team run by another Conti conspirator known as "silver" or "buza." He was recruited to help with coding and directed to work on a malware loader – software designed to get other malicious code running on a victim's machine. Prosecutors said his Google account showed he had also been doing some homework. Investigators found books and videos about malware and hacking alongside Conti malware, ransom notes, and stolen victim data. Prosecutors said he also used Google and ZoomInfo to research potential targets. Lytvynenko wasn't confined to writing code, according to the filing. Evidence from his online accounts showed that he possessed data stolen from eight US victims and four overseas, with the eight American victims reporting more than $1.5 million in losses. Court documents identify several Bitcoin transfers tied to his Conti work, including 0.4 BTC worth $25,042 that prosecutors traced back to one of his victims. He has been ordered to forfeit the same amount. Conti disbanded in 2022 after its internal chats and source code were leaked following the gang's public support for Russia's invasion of Ukraine. Lytvynenko apparently didn't take that as his cue to find another line of work. When Gardaí turned up at his County Cork home in July 2023, they said they found his laptop open, Cobalt Strike running and a Rocket.Chat session connected over Tor. Prosecutors said evidence recovered from the machine showed that his involvement in ransomware activity had continued after Conti disbanded. Lytvynenko was extradited from Ireland to the US in October 2025. The Justice Department says Conti attacked organizations across 47 US states, the District of Columbia, Puerto Rico, and 31 foreign countries between 2020 and 2022. By January 2022, the FBI estimated that victim payouts associated with Conti exceeded $150 million. Lytvynenko will now have four years to contemplate a career change. ®

Manufacturers selling products with digital elements in the EU must now report actively exploited vulnerabilities to cybersecurity authorities under the Cyber Resilience Act's mandatory reporting rules. The reporting duties set out in Article 14 of the CRA became applicable today. Subject to the regulation's exemptions, they apply to manufacturers of products with digital elements made available in the EU, regardless of where those manufacturers are based. Manufacturers must submit an early warning within 24 hours of becoming aware of an actively exploited vulnerability, followed by a more detailed notification within 72 hours. The same deadlines apply to severe incidents affecting the security of products with digital elements. The only difference in timing is related to the final report. Manufacturers must provide a final report on an actively exploited vulnerability within 14 days of making a corrective or mitigating measure available. For serious incidents, the final report is due one month after the first report. Darren Anstee, CTO for security at Netscout, said the reporting deadlines introduce much-needed urgency in working toward global cyber resilience. "The 24-hour window in which an initial warning must be reported creates a level of urgency, with subsequent deadlines ensuring that the gathering and release of additional information is prompt," he said. "Better, more rapid sharing of information helps organisations put defences and mitigating controls in place when they know there is heightened risk." EU and non-EU manufacturers must file these reports through ENISA's Single Reporting Platform (SRP). Notifications are addressed to the coordinating computer security incident response team (CSIRT) determined under the CRA. For an EU manufacturer, this is generally the CSIRT for the member state where it has its main establishment; separate rules determine the coordinator for manufacturers based outside the bloc. Manufacturers must also inform affected users, where appropriate, about actively exploited vulnerabilities or severe incidents. The CRA states that users must be informed of available corrections or mitigations without undue delay. Generally, failures under the CRA are punishable by varying tiers of fines, the most serious of which can reach €15 million ($17.4 million) or 2.5 percent of the offender's annual turnover, whichever is higher. The reporting duties that took effect today are classified as core responsibilities under the act, meaning failures to comply with them could lead to the maximum fines being issued. They are the latest step in the EU's plan to drip-feed tighter security regulations on companies operating in the bloc. Most remaining CRA provisions become applicable on December 11, 2027, at which time manufacturers will also be required to embed security by design and default. That means no default passwords and security updates are no longer optional. Products covered by the CRA will also have to undergo the applicable conformity assessment before being placed on the EU market and bearing a CE mark. More than a deadline The CRA's new rules are not just intended to accelerate manufacturers' responses to security flaws. They are also intended to give businesses a better understanding of their software supply chains. With the reporting clock starting as soon as manufacturers become aware of an issue, they cannot afford to begin mapping an affected product only after a vulnerability or incident emerges. They need a comprehensive view of the affected product and any related products that may share the flaw if they are to meet the deadlines. Furthermore, those requirements demand that manufacturers maintain this understanding throughout each product's lifecycle. Creating a software bill of materials (SBOM) when a product is launched is one thing. The SBOM becomes a mandatory requirement when most of the CRA's remaining provisions become applicable next year. Maintaining that security snapshot over time, however, is intended to help reduce the number and impact of serious cyberattacks across the EU. "What all this means for manufacturers is that secure development, effective vulnerability handling, and traceability across the software supply chain should be elevated to the top of their priority list," said Eran Kinsbruner, veep of product marketing at Checkmarx. "Modern applications are assembled from a complex ecosystem of components, with combinations of proprietary code, open-source packages, third-party components and, increasingly, AI models and services all interconnected," he added. "Organizations need to understand these components, their dependencies and the risks they introduce." Given enough time, the CRA looks set to improve cyber resilience across the board. However, lawyers warn that manufacturers, particularly those outside heavily regulated sectors, must now contend with a growing body of overlapping rules. "The CRA is arriving as organizations are already grappling with a growing body of Digital Decade legislation, including NIS2, DORA, the Data Act, and the AI Act," said Heidi Waem, data, privacy and cybersecurity partner at DLA Piper. "We're seeing the compliance challenge for many businesses evolving beyond understanding single regulations in isolation, but determining how multiple frameworks interact, where requirements overlap and how compliance programmes can be coordinated across them." John Magee, partner and global co-chair of data, privacy, and cybersecurity at the same law firm, added: "Even now we're seeing the breadth of the regulation's reach catching organizations off guard. "Many still associate the CRA primarily with consumer IoT devices, when in reality it applies to a much broader pool of products with digital elements. For compliance teams already very busy managing multiple Digital Decade initiatives, there is a risk that this first wave of CRA obligations has arrived sooner, and with a wider impact, than they had expected." ®

It wasn’t that long ago that ClickFix attacks were exotic. Now the technique has become mainstream as attackers reap its simplicity and effectiveness in infecting users of PCs and Macs alike. All that’s required is a compromised website—a painless enough task—a fake CAPTCHA overlay, and the inclusion of a single terminal command. So many visitors get suckered into pasting and running the command that just about every malware pusher has adopted the technique. Even Kremlin-backed hacking groups are joining in.

“Reddit is becoming post after post after post of people getting their computer infected via ClickFix,” independent researcher Kevin Beaumont observed Thursday. “Legit websites everywhere [are] getting hacked to serve the fake captcha prompts.”

How many of us make things worse

More seasoned Internet users—a fair number who read this site—are quick to dismiss the attack. They typically blame the people who fall for the scams and marvel at their gullibility and lack of attention. The reality is that for more casual users, using computers and the Internet has become so difficult—think impossible-to-close interstitials, CAPTCHAs with an endless series of pictures to analyze, and constantly changing interfaces that bury the features they’re looking for—that they have grown desensitized to instructions that seem ridiculous and burdensome.
