How Social Engineering Exploits Trusted Identities, Platforms, and Workflows

Summary
The article explains how attackers exploit trusted tools and workflows, including an EvilTokens campaign that used Microsoft device-code phishing to target 340+ organizations, and urges teams to prioritize identity behavior, clear ownership, and rapid response.
Key points
- The EvilTokens phishing-as-a-service campaign abused Railway and legitimate Microsoft OAuth device-code flows to target more than 340 organizations.
- Victims were tricked into authenticating attackers’ sessions, granting persistent tokens for services including email, Teams, SharePoint, and OneDrive; the article says password resets did not invalidate the tokens.
- The article describes malicious search results and fake AI support instructions that led users to download malware or execute commands installing the AMOS infostealer.
- It argues that deepfakes and abuse of trusted workflows make identity and behavior signals more useful than relying solely on familiar-looking domains or lures.
- The article cites survey findings that identity-based attacks are organizations’ least-prepared area (26.5%) and that 32% lack ITDR.
- Recommended resilience priorities include reducing alert noise, assigning response ownership in advance, monitoring identity and session behavior, and speeding up action on meaningful signals.
