Hackers are exploiting Microsoft Teams to deceive users into installing remote access tools, granting attackers control over victims’ systems. Trend Micro analyzed an incident where an attacker, impersonating a trusted client, initiated a Teams call and persuaded the victim to download a remote support application. When installing Microsoft Remote Support failed, the attacker recommended AnyDesk, a legitimate tool often misused by cybercriminals.
Once AnyDesk was installed, the attacker executed commands to gather system information and deployed malware, including Trojan.AutoIt.DARKGATE.D, to establish a connection with a command-and-control server. Although the attack was intercepted before data exfiltration occurred, it underscores the need for robust security measures.
Recommendations to mitigate such attacks include:
- Verify Third-Party Claims: Always confirm the identity of technical support providers before granting system access.
- Control Remote Access Tools: Whitelist approved applications and enforce multi-factor authentication to enhance security.
- Employee Training: Educate staff about social engineering tactics, including phishing and vishing, to reduce vulnerability to such schemes. Learn ethical hacking
