> Hunter suffered infostealer compromise exposing 35,081 user credentials and employee access across 37 accounts.

Hunter has been identified as a victim of credential compromise via infostealer malware infection. The incident exposed 35,081 user credentials, 37 compromised employee accounts, and 7 third-party employee credentials. The attack surface includes 34 external-facing DNS records associated with the victim's domain. This represents a supply-chain and credential-theft risk, as the compromised credentials could enable lateral movement, account takeover, or subsequent ransomware deployment. The data was publicly indexed by ransomware operators, indicating the credentials are circulating in attacker communities and pose immediate risk for secondary exploitation.

## Detection guidance (public sample)

### Browser Credential Store Files Accessed via Command Line Utilities

ATT&CK: T1555

Detects shells and copy utilities referencing browser credential database files (Login Data, logins.json, key4.db), which infostealers use to harvest saved passwords. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

title: Browser Credential Store Files Accessed via Command Line Utilities
id: 51d116cd-edca-5600-8f9c-5ebe9ba3dfbb
status: experimental
description: Detects cmd, PowerShell, esentutl, robocopy, xcopy or sqlite3 command
  lines that reference browser credential stores (Chromium Login Data, Firefox logins.json
  and key4.db). This is typical infostealer or post-compromise credential harvesting
  behaviour. It matches on the targeted artefact, not on a specific malware family.
