Meet the Unique New "Hacking" Group: AlphaLock https://www.bleepingcomputer.com/news/security/meet-the-unique-new-hacking-group-alphalock/

It’s not every day that you discover a new Russian hacking group complete with a song and dance routine (performed live), a sleek user interface (with dark mode!) and a clearly thought-out business model. But that is exactly what our security research team discovered with “AlphaLock,” a “pentesting training organization” that trains hackers and then monetizes their services through a dedicated affiliate program.
...
We originally discovered their group through a public Telegram channel that has since become private. This post will serve as a detailed investigation and description of one of the most brazen, strange, and best marketed cybercrime groups to appear in 2023.

  • Cybercrime sophistication and commoditization continues to grow: We now have a real life example of a threat group that seeks to create its own talent pool through a training program, goes to extensive lengths to market itself, and plans to monetize this through a hacker-for-hire scheme. The level of technical sophistication required to do this isn’t very high, but the level of organizational sophistication and business acumen is quite interesting.
  • Ransomware isn’t the only game in town: Cybercriminals typically choose the path of least resistance that is most likely to prove profitable, this has been increasingly the case as the cybercrime ecosystem has evolved into a functional market economy. However AlphaLock represents another potential method to both monetize and democratize cybercrime. This could be a particularly interesting model alternative for ransomware groups if the U.S. follows through with the proposal of banning ransomware payments.
  • A Technical Threat Actor Supply Shortage? One of the most fascinating things about AlphaLock is they want to create a pipeline of talent to populate their hacker marketplace. This suggests that there may be limitations on the supply of talented threat actors that have the required degree of sophistication to the point where they have tried to build their own pipeline of actors.
  • The Brand: Our researchers have noted an increasing focus on group “brand” and identity among financially motivated threat groups. AlphaLock has clearly made significant investments in time to create a brand and reputation for itself. Notice in the final post they even advertise that they are looking to hire someone to market themselves on Telegram and social media.
  • Blurred Lines: Many security practitioners have often assumed that threat actors primarily operate on the dark web. In most cases today this isn’t the case. There are increasingly blurred lines between clear web sites, Tor, and social media applications such as Telegram that create easy avenues for threat actors to congregate and communicate.

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. However, we dug into multi-point ransomware attacks from 2023, and found another factor in ransomware’s staying power: a seemingly endless supply of new cyber crime groups starting ransomware operations.

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.
