A cybercrime forum seller advertised "a full dump of the popular DDoS-Guard online service" for sale, but the distributed denial-of-service defense provider, which has a history of defending notorious sites, has dismissed any claim it's been breached. What's the potential risk to its users?
Ransomware-wielding criminals continue to find innovative new ways to extort victims, develop technically and sidestep skills shortages by delivering ransomware as a service, said Robert Hannigan, the former head of U.K. intelligence agency GCHQ, in his Infosecurity Europe 2021 virtual keynote speech.
Extended detection and response, or XDR, can play an important role in improving the detection of ransomware and supply chain attacks, says Peter Firstbrook of Gartner.
Some security experts are questioning the findings of a recent report by the International Institute for Strategic Studies, a London-based think tank, that concludes China is 10 years behind the United States in "cyber capacity."
Attackers have been exploiting a zero-day flaw in SolarWinds' Serv-U Managed File Transfer Server and Serv-U Secured FTP software, the security software vendor warns. The company has released patched versions that mitigate the flaw, discovered by Microsoft, and is urging users to update.
Threat intelligence researchers are looking closely at REvil, the ransomware gang that infected up to 1,500 companies in a single swoop. A look at the group's online infrastructure shows clear lines to Russian and U.K. service providers that, in theory, could help law enforcement agencies but don't appear eager to...

This edition of the ISMG Security Report features three segments on battling ransomware. It includes insights on the Biden administration's efforts to curtail ransomware attacks, comments on risk mitigation from the acting director of CISA, plus suggestions for disrupting the ransomware business model.
As ransomware attacks become more prolific, their success is being driven by the increasing use of specialists who can refine every stage of an attack. It's a reminder that the goal of cybercrime remains to maximize illicit profits as easily and quickly as possible.
The Biden administration has a message for Russia: Rein in the criminal hackers operating from inside your borders who hit Western targets, or we'll do it for you. But experts say disrupting ransomware will take more than diplomacy or even using offensive cyber operations to target criminal infrastructure.
It was stealthy, and it was widespread. But perhaps the Kaseya VSA ransomware attack wasn't quite as effective and damaging as initially feared, says Michael Daniel, president and CEO of the Cyber Threat Alliance. He explains where defenses succeeded.
The Kaseya VSA ransomware attack was discussed exhaustively over the Fourth of July holiday weekend. But there's one big question that hasn’t been answered, says Tom Kellermann, head of cybersecurity strategy at VMware Carbon Black: "Who gave REvil the zero-day?"
