Microsoft Teams: Now Delivering Ransomware with a Smile
Microsoft Teams is making headlines for all the wrong reasons. Sophos researchers have discovered that cybercriminals are using the platform to spread ransomware through voice phishing and email bombing. With two distinct campaigns exploiting Teams vulnerabilities, it’s a wake-up call for enterprise security as hackers get creative with their social engineering tactics.
Hot Take:
Microsoft Teams has moved from being your go-to platform for ‘productive’ meetings to your worst nightmare, thanks to some clever cybercriminals. Who knew your 10 a.m. ‘Weekly Sync’ could turn into a ‘Weekly Sink’ for your data security?
Key Points:
- Sophos researchers have discovered ransomware being spread via Microsoft Teams, exploiting vishing and email bombing techniques.
- The attacks are attributed to cybercriminal groups STAC5143 and STAC5777, using social engineering and Microsoft Teams vulnerabilities.
- These attacks aim to deliver ransomware that encrypts files and exfiltrates data for extortion.
- In another incident, credentials from major cybersecurity vendors were leaked on the dark web, leading to potential unauthorized access to sensitive systems.
- Both incidents underline the sophistication of current cyber threats and the need for robust security measures.
