Stay Vigilant: New Wave of Phishing Attacks Exploiting Microsoft Teams

There has been a significant increase in highly targeted phishing attacks exploiting Microsoft Teams. Cybercriminals are using increasingly sophisticated tactics to deceive users and compromise businesses.  

How These Attacks Unfold:

• Impersonating Your IT Team: Attackers often pose as members of your “IT Department”, initiating contact through Teams chat or calls. They may claim to be addressing a spam issue, offering technical assistance, or deploying urgent security updates.
• Flooding Your Inbox: In some cases, attackers launch a massive spam campaign.
• Weaponizing Remote Access Tools: Attackers will try to manipulate you into installing remote management software.
• Stealing Credentials and Deploying Malware: Once they gain control of your device, attackers can steal your login credentials, install backdoors, exfiltrate sensitive data, or even deploy ransomware.

Evolving Tactics and Techniques:

Attackers are constantly adapting their methods to bypass security measures and exploit vulnerabilities. Here are some of the recent trends we’ve observed:

• Direct Teams Contact: Attackers are increasingly initiating attacks through direct Teams messages and calls.
• Malicious Links: Attackers may send you deceptive links disguised as legitimate SharePoint files or other seemingly harmless content.
• Unique Attack Kill Chains: Each attack can have a different sequence of actions and payloads, making it difficult to identify a single pattern.

Protect Your Business: Essential Steps to Take

• Be Wary of Unsolicited Communication: Always verify the sender’s identity before engaging in any conversation on Teams.
• Scrutinise Links and Attachments: Never click on links or open attachments from unknown or suspicious sources.
• Exercise Extreme Caution with Remote Access Tools: Only grant remote access to your device to trusted individuals after verifying their identity.
• Enable Multi-Factor Authentication (MFA):  Activate MFA on all your accounts to provide an additional layer of security.
• Educate Your Team: Use our tools to train your employees to recognise phishing attacks, understand the risks, and follow security best practices.
• Strengthen Your Security Posture: Speak to Solsoft about additional security services such as SOC / SIEM
