There are several malicious fake updates campaigns being run across thousands of compromised websites. Here I will walk through one with a pattern that doesn’t match with others I’ve been tracking. This campaign appears to have started around July 19th, 2023. Based on a search on PublicWWW of the injection base64 there are at least 434 infected sites. I’m calling this one ClearFake until I see a previously used name for it. The name is a reference to the majority of the Javascript being used without obfuscation. I say majority because base64 is used three times. That’s it. All the variable names are in the clear, no obfuscation on them. One noticeable difference from SocGholish is that there appears to be no tracking of visits by IP or cookies. As an analyst you can you go back to the compromised site over and over coming from the same IP and not clearing your browser cache. This also means the site owner is more likely to see the infection as well.

Ransomware’s business model is a big part of what’s made it such a potent threat for so many years.

Negotiating with LockBit: Uncovering the Evolution of Operations and Newly Established Rules
What defines success for ransomware actors during an attack? Breaching a victim’s network, exfiltrating valuable data, and encrypting systems are crucial components. However, the ultimate measurement of success is the actor’s ability to extort a ransom payment, which determines if they achieve their financial goals. Navigating the ransom negotiation phase, whether conducted by the victims themselves or designated recovery firms, demands a high level of expertise and a deep understanding of the attackers involved. This includes studying of the threat actor’s profile, tactics, and evolving strategies. In this complex landscape, there is no one-size-fits-all playbook for successfully managing the negotiation phase, as each ransomware group exhibits distinct behaviors and adopts new tactics shaped by many factors.
Cookieless DuoDrop: IIS Auth Bypass & App Pool Privesc in ASP.NET Framework (CVE-2023-36899 & CVE-2023-36560)
In modern web development, while cookies are the go-to method for transmitting session IDs, the .NET Framework also provides an alternative: encoding the session ID directly in the URL. This method is useful to clients that do not support cookies.
The LockBit ransomware gang is one of the most notorious organized cybercrime syndicates that exists today. The gang is behind attacks targeting private-sector corporations and other high-profile industries worldwide. News and media outlets have documented many LockBit attacks, while security vendors offer technical assessments explaining how each occurred. Although these provide insight into the attacks, I wanted to know more about the human side of the operation to learn about the insights, motivations, and behaviors of the individuals on the other side of the keyboard. To prepare for this project, I spent months developing several online personas and established their credibility over time to gain access to the gang’s operation.
The ASEC analysis team recently discovered that a Linux malware developed with Shc has been installing a CoinMiner.
