The Shift from Email to Collaboration Attacks: What You Need to Know

The Attack Surface Has Expanded

Microsoft Teams. Slack. Zoom. Google Chat. Collaboration platforms have become the backbone of modern work.

These tools make communication faster—but they also create new, often unprotected pathways for malware, phishing links, and data theft.

Why Collaboration Platforms Are Vulnerable

Most organizations have invested heavily in email security. But collaboration platforms often receive far less scrutiny—and attackers have noticed.

A malicious link sent via Teams looks exactly like a legitimate one. A file shared through Slack bypasses email security controls entirely. An attacker who compromises one account can reach every person in your organization through internal channels that employees inherently trust.

What Attackers Are Doing

Sending phishing links through direct messages and channel posts. Sharing malware-laden files that bypass email filters. Impersonating executives and IT staff to request credentials or transfers. Using compromised accounts to launch attacks against partners and customers.

What You Need

Security coverage that extends beyond email to include all collaboration platforms your organization uses. This means scanning links and files shared through Teams, Slack, and other platforms—with the same rigor applied to email.

The perimeter has expanded. Your security coverage needs to expand with it.
