Security News > 2023 > October > MATA malware framework exploits EDR in attacks on defense firms
An updated version of the MATA backdoor framework was spotted in attacks between August 2022 and May 2023, targeting oil and gas firms and the defense industry in Eastern Europe.
The updated MATA framework combines a loader, a main trojan, and an infostealer to backdoor and gain persistence in targeted networks.
The MATA version in these attacks is similar to previous versions linked to the North Korean Lazarus hacking group but with updated capabilities.
In applicable cases where the targets were Linux servers, the attackers employed a Linux variant of MATA in the form of an ELF file, which appears to be similar in functionality to the third generation of the Windows implant.
The deployment of multiple malware frameworks and MATA framework versions in a single attack is very uncommon, indicating a particularly well-resourced threat actor.
