Earlier this week, KrebsOnSecurity revealed that the darknet website for the Snatch ransomware group was leaking data about its users and the crime gang’s internal operations. Today, we’ll take a closer look at the history of Snatch, its alleged founder, and their claims that everyone has confused them with a different, older ransomware group by the same name. According to a September 20, 2023 joint advisory from the FBI and the U.S. Cybersecurity and Infrastructure Security Administratio n (CISA), Snatch was originally named Team Truniger , based on the nickname of the group’s founder and organizer — Truniger. The FBI/CISA report says Truniger previously operated as an affiliate of GandCrab , an early ransomware-as-a-service offering that closed up shop after several years and claims to have extorted more than $2 billion from victims . GandCrab dissolved in July 2019, and is thought to have become “ REvil ,” one of the most ruthless and rapacious Russian ransomware groups of all...

On September 27, 2023, Progress Software published a security advisory on multiple vulnerabilities affecting the Ad Hoc Transfer module in WS_FTP Server , a secure file transfer solution. There are a number of vulnerabilities in the advisory, two of which are critical (CVE-2023-40044 and CVE-2023-42657). Rapid7 is not aware of any exploitation in the wild as of September 29, 2023. Our research team has identified what appears to be the .NET deserialization vulnerability (CVE-2023-40044) and confirmed that it is exploitable with a single HTTPS POST request and a pre-existing ysoserial.net gadget. The vulnerabilities in the advisory span a range of affected versions, and several affect only WS_FTP servers that have the Ad Hoc Transfer module enabled. Nevertheless, Progress Software’s advisory urges all customers to update to WS_FTP Server 8.8.2, which is the latest version of the software. Rapid7 echoes this recommendation.The vendor advisory has guidance on upgrading, along with inf...

The victim shaming site operated by the Snatch ransomware group is leaking data about its true online location and internal operations, as well as the Internet addresses of its visitors, KrebsOnSecurity has found. The leaked data suggest that Snatch is one of several ransomware groups using paid ads on Google.com to trick people into installing malware disguised as popular free software, such as Microsoft Teams , Adobe Reader , Mozilla Thunderbird , and Discord . First spotted in 2018 , the Snatch ransomware group has published data stolen from hundreds of organizations that refused to pay a ransom demand. Snatch publishes its stolen data at a website on the open Internet, and that content is mirrored on the Snatch team’s darknet site, which is only reachable using the global anonymity network Tor .

Both Apple and Google have recently reported critical vulnerabilities in their systems—iOS and Chrome, respectively—that are ultimately the result of the same vulnerability in the libwebp library: On Thursday, researchers from security firm Rezillion published evidence that they said made it “highly likely” both indeed stemmed from the same bug, specifically in libwebp, the code library that apps, operating systems, and other code libraries incorporate to process WebP images. Rather than Apple, Google, and Citizen Lab coordinating and accurately reporting the common origin of the vulnerability, they chose to use a separate CVE designation, the researchers said. The researchers concluded that “millions of different applications” would remain vulnerable until they, too, incorporated the libwebp fix. That, in turn, they said, was preventing automated systems that developers use to track known vulnerabilities in their offerings from detecting a critical vulnerability that’s under act...

There are no reliable ways to distinguish text written by a human from text written by an large language model. OpenAI writes : Do AI detectors work? In short, no. While some (including OpenAI) have released tools that purport to detect AI-generated content, none of these have proven to reliably distinguish between AI-generated and human-generated content. Additionally, ChatGPT has no “knowledge” of what content could be AI-generated. It will sometimes make up responses to questions like “did you write this [essay]?” or “could this have been written by AI?” These responses are random and have no basis in fact. To elaborate on our research into the shortcomings of detectors, one of our key findings was that these tools sometimes suggest that human-written content was generated by AI.
