BlackCat Ransomware

The BlackCat ransomware, also known as ALPHV, is a prevalent threat and a prime example of the growing ransomware-as-a-service (RaaS) gig economy. The unusual programming language (Rust), the variety of target devices and potential entry points, and its association with active threat action organisations make it unique . The goal data is encrypted, exfiltrated, and used for “double extortion,” where attackers threaten to reveal the stolen material to the public if the ransom is not paid. However, BlackCat’s arrival and execution differ according to the actors employing it.

BlackCat was one of the first ransomware families created in the Rust programming language, and it was first noticed in November 2021. This ransomware makes an effort to avoid detection by employing a current language as its payload, especially by traditional security solutions that may still be catching up in their capacity to analyse and parse binaries generated in such language. BlackCat has the ability to target a variety of hardware and OSes.

RECENT ACTIVITY

The ALPHV/BlackCat ransomware organisation revealed last week that they had assembled a searchable database of information from victims who refused to pay the ransom. The hackers made it evident that the repositories had been indexed and that searching for material by filename or content found in documents and photographs was effective.

The accuracy of the data, which are taken from the “Collections” section of BlackCat’s leak site, may not be the finest. However, they nevertheless represent an advancement in the extortion tactics of online criminals.

The developers of the BlackCat ransomware assert that they do this to make it simpler for other thieves to locate passwords or private information about businesses. When they built a searchable website using information allegedly taken in an attack on an Oregon hotel and spa in the middle of June, the gang already gave this tactic a go. The website allowed staff and visitors to the spa facilities to determine whether their personal data had been taken during the ransomware assault.

This is a step forward in the extortion business as it puts pressure on the victim to pay the ransom and have the data removed from the web and avoid the potential risk of class action lawsuits.
