A Russian advanced persistent threat (APT) group known as Turla has been using a new backdoor called 'StockStay' to target Ukrainian government and military organizations. This espionage campaign aims to gather sensitive information amidst the ongoing conflict in Ukraine. The backdoor allows attackers to maintain persistent access to compromised systems, facilitating data theft and surveillance. The situation raises significant concerns about the security of vital governmental infrastructure and the potential for further cyberattacks as tensions in the region continue to escalate. Ukrainian authorities and cybersecurity experts are urged to enhance their defenses against this ongoing threat.
