Seedworm Group Suspected in Sweeping Espionage Campaign Across Telecom and IT Services

An espionage campaign tentatively linked to the Iranian-backed Seedworm group has been using compromised organizations as stepping stones to additional victims or targets that may have been compromised solely to perform supply-chain-type attacks on other organizations. The attackers primarily used legitimate tools, publicly available malware, and living-off-the-land tactics, with a significant interest in Exchange Servers. While the ultimate end goal remains unknown, the focus on telecom operators suggests the attackers are gathering intelligence on the sector, potentially pivoting into communications surveillance.
