TL;DR: Public sector organisations are facing an exponential increase in business email compromise and credential phishing, according to Abnormal AI, as threat actors adapt tactics to target employees and volunteers across state and local governments. Traditional inbox controls must account for user vulnerability and constrained public-sector resourcing, not just message filtering.
Editorial analysis by NHI Mgmt Group, based on content published by Abnormal AI: “A CISO Fireside Chat with the State of Connecticut”.
Key questions
Q: What breaks when government inboxes rely on user judgement to stop phishing?
A: User judgement fails when messages are crafted to look routine, urgent, or personally relevant, which is exactly how credential phishing and BEC work.
Q: Why do credential phishing attacks create disproportionate risk for public-sector teams?
A: Public-sector teams often manage broad, distributed communication channels with constrained staff and high-volume correspondence.
Practitioner guidance
- Tighten inbox trust controls Apply stronger validation to messages that request payment, access changes, or urgent follow-up so a compromised sender cannot easily drive action through routine channels.
- Harden account recovery paths Review password reset, MFA reset, and help-desk verification steps because credential phishing often turns into account takeover when recovery is too permissive.
- Prioritise high-risk user groups Focus awareness, monitoring, and response tuning on employees and volunteers who exchange externally facing email most often, especially where approval chains are informal.
Bottom line: Credential phishing and business email compromise are rising pressures for government inboxes, and the attack path is built around trusted communication rather than technical intrusion.

Credential phishing is now a public-sector identity governance problem, not just an email-security problem. The article makes clear that attackers are targeting the people and communication patterns that government operations depend on. That shifts the centre of gravity from blocking bad messages to governing how trust is established, transferred, and abused in inbox workflows. Practitioners should treat mailbox identity as an access surface with its own controls and failure modes.
A question worth separating out:
Q: What should teams watch for after one staff mailbox is compromised?
A: They should look for lateral phishing, impersonation attempts, and contact lists harvested from public directories or prior mail threads. A single trusted account can seed many follow-on attacks, especially in departments where external communication is expected. Monitoring should focus on unusual outbound patterns and new recipient clusters.
