## Threat Profile

A sophisticated phishing campaign called “GitBait” has been caught targeting Mexico’s financial sector with a level of precision rarely seen in credential-theft operations. The campaign abuses GitHub Pages, a widely trusted free hosting service, to deliver fake banking portals that look nearly identical to the real thing. Victims who land on these pages are tricked […] The post GitBait Phishing Campaign Abuses GitHub Pages to Attack Financial Institutions appeared first o…

### Phishing-link click correlated to endpoint execution

**Defender KQL:**
```kql

// never spawn a non-browser child process, so the join eliminates the

### IOC-driven hunts (use shared templates)

These are standard IOC-substitution hunts — the canonical SPL and KQL live once in [`_TEMPLATES.md`](../_TEMPLATES.md), so we don't repeat the same boilerplate on every CVE / hash / network-IOC briefing.

- **Network connections to article IPs / domains** ([template](../_TEMPLATES.md#network-ioc)) — phase: **c2**, confidence: **High**
  - IP / domain IOC(s): `176.97.214.92`, `soporte-index.github.io`, `soporte-index69.github.io`, `sntdr-soporte.github.io`, `v9-soporte.github.io`, `soporte169.github.io`, `soporte1505.github.io`, `soporte16032k.github.io` _(+23 more)_
