UNC1549: Iranian Cyber Espionage Breaches 11 European Telecoms Using LinkedIn Lures
In mid-2025, an Iran-affiliated cyber espionage group tracked as UNC1549 executed a coordinated attack targeting 11 European telecommunications firms. Using LinkedIn job recruitment lures and the custom MINIBIKE malware, the attackers successfully infiltrated 34 devices within these organizations, gaining persistent access to sensitive internal systems. The campaign, discovered by Swiss cybersecurity company PRODAFT, leveraged sophisticated social engineering alongside stealthy lateral movement, indicating considerable operational capability and intent to harvest confidential information potentially valuable for nation-state interests. This incident underscores a rising trend of strategic supply chain and telecom attacks using spear phishing and novel malware, highlighting the importance of strong east-west traffic controls and threat detection. It also reflects growing geopolitical tensions fueling state-sponsored cyber campaigns against critical infrastructure in Europe.
