Intelligence Summary
Attackers are abusing Microsoft Teams voice calls to impersonate corporate IT support. The scam targets employees and persuades them to install the EtherRAT malware. Once installed, the malware can provide attackers initial access to corporate environments. This creates a pathway for further intrusion, data theft, and lateral movement. Users should be cautious of unexpected Teams calls requesting software installs and verify requests through official IT channels.
