TinyTurla is a sophisticated malware linked to the Russia-sponsored threat actor, Turla APT. This malicious software has been utilized in a targeted campaign against Polish Non-Governmental Organizations (NGOs), particularly those with connections to supporting Ukraine. TinyTurla operates as a backdoor, infiltrating systems without the user's knowledge, and is designed to execute specific tasks that disrupt operations and potentially steal sensitive information. The deployment of TinyTurla involves a complex method of operation. It abuses PDF and MSBuild project files to deliver its payload in a fileless manner, making it harder to detect. Once inside the system, the .log file, also an MSBuild project, is scheduled to be executed using 'MSBuild.exe' through Task Scheduler to carry out backdoor activities. The malware manages its operations by using multiple threads, each designed to execute specific tasks, thereby increasing its efficiency and effectiveness. This campaign was identified by researchers from Cyble Researchers and Intelligence Labs (CRIL). The threat actors behind this campaign have been using socially engineered emails as a delivery mechanism. These emails often contain documents pitching invitations to human rights seminars or providing public advisories, serving as a lure to infect users with TinyTurla. The use of such deceptive tactics underscores the evolving sophistication of cyber threats and the need for constant vigilance and robust cybersecurity measures.
