Recent research by Trend Micro reveals that Albabat ransomware has evolved, now targeting not just Windows but also Linux and macOS systems. The ransomware, which initially only affected Windows, has expanded to exploit multiple operating systems, highlighting its increasing sophistication. Trend Micro’s findings also show that the latest versions of the ransomware, 2.0.0 and 2.5, now collect system and hardware information from Linux and macOS devices, in addition to Windows. These versions retrieve configuration data from GitHub, where the ransomware group stores key components of its operations.
The ransomware uses a “User-Agent” string labeled “Awesome App” to interact with GitHub’s REST API and gather configuration data.
This method allows attackers to centralize control over Albabat’s operations and easily update the malware’s tactics. Additionally, the ransomware encrypts a wide range of file extensions, such as .exe, .dll, and .mp3, while avoiding certain folders to evade detection. It also terminates various processes like task managers and productivity software to prevent users from interfering with the encryption process.
The attackers store the stolen data in a PostgreSQL database, which helps them monitor infections, track ransom payments, and potentially sell the sensitive data. The use of GitHub for operational efficiency allows the ransomware group to maintain centralized control over its attacks, making it more adaptable. Trend Micro also noted the ongoing development of Albabat, with a potential version 2.5 currently under development.
This indicates that ransomware attacks will continue to evolve, posing an increasing threat to organizations across different operating systems.
Security experts recommend organizations adopt robust cybersecurity measures to mitigate such risks. These measures include implementing strong access controls, keeping systems updated, and ensuring secure backups. Network segmentation and user training can help prevent initial infections, while proactive AI-powered security platforms can predict and prevent emerging threats like Albabat. The rapid evolution of ransomware, as demonstrated by Albabat, highlights the need for continuous monitoring of indicators of compromise (IoCs) and leveraging threat intelligence to stay ahead of these evolving threats.
