Fog Ransomware Group
Fog ransomware, a variant of the STOP/DJVU family, has posed a significant threat since its emergence in November 2021. Known for its rapid encryption capabilities and double extortion tactics, the group has shifted its focus towards more lucrative targets, including the financial sector. The ransomware typically encrypts files with extensions like .fog or .flocked and demands a ransom in Bitcoin for decryption. The group's ability to infiltrate systems through sophisticated techniques, such as privilege escalation and data exfiltration, distinguishes it as a formidable adversary in the cybersecurity landscape.
Potential Penetration Methods
The Fog ransomware group likely penetrated Welker's systems through compromised VPN credentials or by exploiting known vulnerabilities in applications. Once inside, the ransomware encrypted critical files and deleted backups, hindering recovery efforts. The attack underscores the importance of comprehensive cybersecurity measures, particularly in industries handling sensitive data.
