NAMES AND ALIASES

APT-C-36 and Blind Eagle

APT-C-36 is tracked under its research designation and the Blind Eagle name. It is one entry among the threat groups in our platform, and its commodity-RAT approach overlaps with eCrime crews like Crazy Evil.

GROUP PROFILE

Spanish-language phishing against Colombia

APT-C-36 focuses on Colombia, hitting government agencies, financial institutions and businesses, with some activity across Latin America. It mixes espionage and financially motivated theft, relying on social engineering more than exploits.

Our record places its origin as Colombia and ties it to campaigns against government and finance. It spoofs Colombian judicial and tax authorities in its lures, and one operation was exposed when an attacker's own workstation got infected by an infostealer.

The group's approach is cheap and effective: phishing with SVG attachments, loaders staged on GitHub, and a rotating bench of commodity RATs, refreshed often enough to stay ahead of signature-based detection.

ATTACK LIFECYCLE

SVG phishing into commodity RATs

The stages below come from 2026 APT-C-36 activity in posts we track on our IOC Hunter feed.

Initial Access

Spear-phishing remains the front door. In the 2026 campaign Hunt.io tracked as Operation Neusploit, APT28 sent convincing spear-phishing from already-compromised government accounts and abused a Microsoft Office security bypass (CVE-2026-21509) to kick off a fileless chain. A separate June 2026 cluster delivered the LameHug malware through spear-phishing ZIP archives using double-extension lures.

CVE-2026-21509

A Microsoft Office security bypass used to open the fileless chain in Operation Neusploit, and again in the PixyNetLoader intrusion chain. Both campaigns paired the exploit with spear-phishing from compromised accounts rather than mass exploitation.

PixyNetLoader tracking

A clustering of roughly 90 loader samples across four sub-families from 2024 to 2026, with steganography and cloud C2, also linking to related APT28 tooling such as SlimAgent and Graphite.
