Browser-Based Threat Alert: Increased Phishing Attacks on Collaboration Platforms Highlight the Importance of Zero-Trust Browser Protection

Phishing attacks have long been a serious threat to businesses, but recent reports indicate that the problem is becoming even more pervasive. Email remains a primary target, but attackers are also expanding their focus to collaboration platforms such as Slack and Microsoft Teams. With the shift to hybrid work environments, these platforms have become popular avenues for exploitation by opportunistic cybercriminals. As a result, companies are grappling with a growing threat surface, and many feel vulnerable to attacks delivered through their collaboration tools.

The Growth of Attacks from Non-Email Platforms

Traditionally, email has been the primary attack vector for phishing and other messaging-based attacks. However, recent data from the “State of Email Security” (SOES) report published by Mimecast indicates that newer collaboration technologies are also being targeted. In the past 12 months, 97% of companies surveyed experienced at least one email phishing attack, and three-quarters expected to incur significant costs from email-based attacks. Most concerning, however, is the increase in cyberattacks via collaboration platforms. Nearly three-quarters of companies surveyed feel it is likely or extremely likely that their company will suffer an attack delivered through their collaboration tools.

This threat is only exacerbated by the fact that attacks on messaging and collaboration software are a growing source of compromise. The Anti-Phishing Working Group detected 1.3 million phishing attacks in the third quarter of 2022, up from 1.1 million attacks in the second quarter. Cybercriminals are getting more sophisticated, with 19% of phishing attacks successfully bypassing platform defenses.

While email remains a key attack vector, collaboration tools provide a new and expanding threat surface for bad actors. Companies in various industries, including consumer services, energy, healthcare, and media and entertainment, are particularly susceptible to these threats. It’s crucial to implement effective security measures, including distinguishing bots with human verification tests.
