Hackers targeted Ukrainian government agencies with a phishing campaign using an open-source program called MerlinAgent, according to the latest research.
In early August, an unidentified threat actor tracked as UAC-0154 sent malicious emails to its targets, purportedly containing security tips from Ukraine's computer emergency response team (CERT-UA).
These emails contained malicious attachments that infected victims' computers with the MerlinAgent tool.
With the tool, attackers could gain remote access to the victim's systems, execute commands, and download or delete files.
MerlinAgent was already used earlier in July to launch attacks on Ukrainian government agencies, according to CERT-UA.
The tool has an open-source code posted on GitHub by a user with the nickname Russel Van Tuyl. Merlin is a remote-access tool (RAT) that allows users to control and access a targeted computer remotely, typically over the internet.
Russel Van Tuyl said that Merlin was his first attempt at learning the Golang programming language.
According to the developer’s note, the tool was intended to only be used during research and authorized testing.
However, in the ongoing cyber war between Ukraine and Russia, hackers from both countries use simple techniques like phishing and open-source offensive security tools as part of their attacks.
