Google issues new ‘warning’ in Microsoft Teams chat invitations and helpdesk scam

Google has warned about a new cybercrime group that uses Microsoft Teams chat invitations and fake helpdesk messages to steal credentials and deploy malware. Researchers at Google Threat Intelligence Group (GTIG) have claimed that a cybercriminal group (UNC6692) conducted a major email hacking campaign last year. This campaign mainly targeted companies by overwhelming their employees with spam emails before connecting with them via Teams under the pretext of offering technical assistance. The attackers then tricked users into installing malicious tools that enabled them to maintain access to compromised systems.
