Phishing has been a longstanding threat but in 2026 attackers are using artificial intelligence to craft highly credible and context aware messages at scale. These messages mimic business communication patterns and incorporate personal data harvested from social media and public sources. The result is phishing content that can deceive even experienced professionals.

Large scale credential leaks over past years created vast datasets of login information. Attackers now use automated tools to test these credentials against business systems at scale. With incomplete MFA adoption and password reuse this remains a persistent threat.
Unauthorized account access
Data theft and privilege escalation
Disruption of user services
Enforce strong password policies and universal multi factor authentication
Use rate limiting and bot detection mechanisms
Monitor for anomalous login attempts across systems
Educate users about credential reuse risks
Our teams assist with identity security enhancements and threat monitoring. Engage Brigient to fortify authentication and reduce account fraud.
Nation state actors and well resourced criminal groups conduct long term espionage campaigns focused on strategic industries. These campaigns use stealthy techniques to maintain presence and exfiltrate intelligence or intellectual property.
Loss of proprietary research or confidential strategy
Corruption of operational data
Regulatory scrutiny and compliance risk
Use intrusion detection and threat hunting tools
Deploy network segmentation and micro segmentation
Monitor for indicators of compromise across the environment
