Cybercriminals will stop at nothing to infiltrate organizations, and phishing attacks remain one of their most common — and successful — approaches. Despite efforts to build awareness and train people to recognize fake messages, hackers are still successfully impersonating individuals and brands and tricking recipients into divulging sensitive information. Microsoft Teams is a popular target for these bad actors, but new automatic warnings aim to curb the attacks.
Users now receive Microsoft Teams phishing alerts on chats from external domains. By proactively warning users about the potential for the message to come from a nefarious sender, there’s less risk of a successful attack.
Protecting Your Networks With Teams Anti-Phishing Updates
The rollout of the Microsoft Teams phishing alerts didn’t require any action by network administrators. With the addition of this feature, the system automatically checks the first time any message from a sender outside the organization arrives in a user’s chat for phishing risk.
If the system detects a suspicious message, a pop-up warning will alert the user that the message might be a phishing attempt and prompt them to accept or block it. Accepting the message means accepting the risk that it's malicious, and the user should be cautious when interacting with the sender.
With this type of phishing protection, Teams places some of the burden for cybersecurity on the user. Instead of automatically blocking all questionable messages, users can investigate further and make educated decisions. It is possible to block all external communications from Teams. Still, if your company regularly communicates via Teams with people outside your organization, that’s not a practical solution.
Cybersecurity and Blocking Phishing Attacks on Your Company
Phishing attacks on companies using Microsoft Teams are insidious and damaging. One recent spate of attacks underscored the need for Microsoft Team phishing alerts. After bombarding a user’s inbox with spam emails, a Russian cybercrime group sent a Teams message impersonating IT. It claimed to be able to fix the issue.
Solving the issue required the user to give the hacker their login credentials and grant remote access to their computer. Doing so opens the door to all sorts of mayhem, and it’s only a matter of time before the hackers infect the system with malware. Introducing spam protection for Teams and phishing alerts can help keep this from happening. However, it still requires vigilance and knowledge on the part of your employees.
Your company is still responsible for training employees to recognize and respond to phishing messages. Even with Teams security alerts in place, individuals should remain suspicious of messages from external or unknown senders and react accordingly. Urgent messages, unrecognized URLs, generic greetings, misspellings, grammatical errors, and attachments that launch unexpected downloads are all telltale signs of trouble.
The addition of Microsoft Teams phishing alerts gives your company additional protection against destructive cyberattacks. It may not block all attacks, but it's impossible to tell how many it will thwart by giving users a heads-up.
