Hello everyone! Great news for my open source Scanvus project! You can now perform vulnerability checks on Linux hosts and docker images not only using the Vulners.com API, but also with the Vulns.io VM API. It’s especially nice that all the code to support the new API was written and contributed by colleagues from Vulns.io. […]

KrebsOnSecurity turns 12 years old today. That's a crazy long time for an independent media outlet these days, but then again I'm liable to keep doing this as long as they keep letting me! Thanks to your readership and support, I was able to spend more time in 2022 on in-depth investigative stories -- the really satisfying kind with the potential to affect positive change. Some of that work is highlighted in the 2022 Year in Breaches review below.

Hello everyone! This episode will be about Microsoft Patch Tuesday for December 2022, including vulnerabilities that were added between November and December Patch Tuesdays. As usual, I use my open source Vulristics project to analyse and prioritize vulnerabilities. Alternative video link (for Russia): https://vk.com/video-149273431_456239112 But let’s start with an older vulnerability. This will be another example why […]

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.

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.

Hello everyone! In my English-language telegram chat avleonovchat, the question was asked: “How to find zero day vulnerabilities with Qualys?” Apparently this question can be expanded. Not just with Qualys, but with any VM solution in general. And is it even possible? There was an interesting discussion.

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.

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 vulnerability 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.

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, this week saw its database of contact information on more than 80,000 members go up for sale on an English-language cybercrime forum. Meanwhile, the hackers responsible are 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.

Ransomware groups are constantly devising new methods for infecting victims and convincing them to pay up, but a couple of strategies tested recently seem especially devious. The first centers on targeting healthcare organizations that offer consultations over the Internet and sending them booby-trapped medical records for the "patient." The other involves carefully editing email inboxes of public company executives to make it appear that some were involved in insider trading.
