FIN8 Introduces Revamped Backdoor to Deliver BlackCat Ransomware

The Main Points:

– FIN8, a financially motivated threat actor, has been observed using a “revamped” version of a backdoor called Sardonic.
– The purpose of this new development is to deliver the BlackCat ransomware.
– FIN8 is diversifying its focus and aiming to maximize profits from infected entities.


The notorious cybercriminal group known as FIN8 has made a significant adaptation to their tactics. They have introduced a “revamped” version of their backdoor called Sardonic, which now serves as a delivery mechanism for the BlackCat ransomware. This development is part of FIN8’s strategy to broaden their horizons and increase their financial gains from compromised targets.

The cybersecurity experts at the Symantec Threat Hunter Team, a division of Broadcom, have closely monitored FIN8’s activities. According to their observations, this new variant of Sardonic allows the threat actors to infect systems with the BlackCat ransomware, which encrypts files and demands a ransom to unlock them. This sophisticated combination of the backdoor and ransomware further emphasizes FIN8’s determination to maximize their profits.

In the past, FIN8 has predominantly focused on financially motivated attacks, targeting organizations in the retail, hospitality, and entertainment sectors. However, with the introduction of this enhanced backdoor, they have demonstrated their intention to diversify their focus and maximize their revenue streams from infected entities. This strategic move enables them to exploit a wider range of potential victims and potentially increase the success rate of their attacks.

The threat landscape continues to evolve, and cybercriminals are constantly finding innovative ways to exploit vulnerabilities. The introduction of the revamped Sardonic backdoor by FIN8 highlights the need for organizations to remain vigilant and up to date with the latest cybersecurity measures. Ensuring system patches and updates are promptly applied, implementing robust security solutions, and educating employees about potential threats are all essential steps in countering the ever-evolving tactics used by threat actors like FIN8.

In summary, FIN8, a financially motivated cybercriminal group, has introduced a revamped version of its backdoor, Sardonic, to deliver the BlackCat ransomware. This move demonstrates their determination to diversify their focus and maximize their profits from infected entities. Organizations must remain vigilant and implement robust cybersecurity measures to protect themselves against such evolving threats.Original Article:
