Cybersecurity threats rise as attackers exploit enterprise collaboration tools

Cybersecurity researchers at Palo Alto Networks’ Unit 42 report a fourfold increase in attackers abusing enterprise collaboration tools over the last 12 months. These threat actors exploit the inherent trust in communication platforms to conduct identity phishing, credential theft, and malware delivery. Most of these incidents originate from traditional phishing attacks; once attackers gain access to an internal tool, their malicious activity often appears as normal user collaboration, making detection difficult.

To combat evolving threats like AI-weaponized phishing and unmanaged workloads, security experts advocate for Zero Trust Architecture (ZTA). This model moves away from obsolete perimeter-based security, such as traditional firewalls and VPNs, in favor of three core principles: explicit verification of all users and devices, least privilege access through just-in-time controls, and a continuous assumption of breach to contain potential lateral movement within a network.
