Estimated read time 2 min read

Have you caught wind of APT-C-36, the digital shadow lurking across South America?

APT-C-36, dubbed Blind Eagle, is not your average cyber adversary. This Advanced Persistent Threat entity, originating from the depths of South America, has been pinpointed by the keen eyes at the 360 Advanced Threat Research Institute.

Since 2018, they’ve been diving deep, unmasking the organization’s relentless cyber espionage campaigns that have predominantly plagued Colombia, with tendrils reaching out to Ecuador and Panama.

Escalating Digital Sabotage

APT-C-36’s Arsenal Expansion

Crafty as ever, APT-C-36 has been evolving, attempting to harness the notorious Amadey botnet Trojan.

According to the detailed analysis by 360 Advanced Threat Research Institute, this modular malware surfaced in the shadier corners of Russian cyber forums back in late 2018 and boasts an alarming skill set: from intranet invasion to data pilfering, and from script slinging to DDoS assaults.

Dissecting the Cyber Ambush

The Amadey Assault Blueprint

The researchers paint a vivid picture: an unsuspecting individual clicks on a PDF, which is actually a Trojan horse delivering a VBS script from a cloud service.

Ingeniously encrypted, the script morphs and mutates, unleashing a Powershell exploit that deciphers itself from base64 encoding to download a double whammy of payloads from a remote host.
