The X_Trader software supply chain attack that led to last month's 3CX breach has also impacted at least several critical infrastructure organizations in the United States and Europe, according to Symantec's Threat Hunter Team.

North Korean-backed threat group linked to the Trading Technologies and 3CX attacks used a trojanized installer for X_Trader software to deploy the VEILEDSIGNAL multi-stage modular backdoor onto victims' systems.
