Devman Ransomware Gang Unleashes Holiday Blitz: Multiple Organizations Hit in Late December Surge

As the world wound down for the holidays, the notorious Devman ransomware group ramped up its criminal operations, unleashing a series of targeted attacks against diverse organizations. In a span of just a few days, Devman publicly listed at least four new victims, marking a chilling reminder that cybercrime doesn’t take a holiday break - even as many organizations do.

Inside the Devman Holiday Offensive

Ransomware groups are notorious for timing their attacks to coincide with weekends and holidays, exploiting the reduced presence of IT staff and delayed incident response. Devman’s latest spree - targeting oppor**nity*****.org, Intonu.com, Jennings SD, and sharinc.org - fits this pattern to a tee. The attacks were discovered and indexed by ransomware.live, a platform that tracks leaks and public disclosures by ransomware operators, between December 27 and 28, 2025. Estimated attack dates range from December 25 to December 28, suggesting a coordinated end-of-year offensive.

While the precise nature and impact of each attack remain unclear - details such as the type of data stolen or the sectors affected were not disclosed - Devman’s inclusion of these organizations on its leak site signals that negotiations may have stalled or that the group is applying pressure for ransom payments. Notably, ransomware.live’s legal disclaimer emphasizes that it does not access or redistribute stolen data, only reporting what is already made public by the attackers themselves.

The lack of transparency highlights a systemic challenge in ransomware reporting: without victim disclosures, the full scale and consequences of such attacks often remain hidden. What is clear, however, is that Devman continues to evolve its tactics, leveraging public shaming and the threat of leaks to maximize leverage over its targets. The group’s recent activity also serves as a stark warning to organizations: the festive season is prime time for cybercriminals, making vigilance and preparedness more critical than ever.

After the Breach: Lessons for the New Year

As we enter 2026, the Devman blitz is a sobering reminder of the relentless, opportunistic nature of cybercrime. Organizations - regardless of size or sector - must treat cybersecurity as a year-round priority, especially during periods of low staffing or public holiday lulls. For now, the full fallout from Devman’s December rampage remains to be seen, but one thing is certain: the cybercriminal calendar never sleeps.
