There have been reports that an organized threat actor, known as Blind Eagle (tracked as APT-C-36), has re-appeared again with a refined toolset and one of the most elaborate infection chains in the history of cyberattacks targeting Colombian and Ecuadorian organizations.
Blind Eagle is a Spanish-speaking hacker group and recently researchers at Check Point uncovered the group’s latest:-
As of 2018, Blind Eagle has been attacking indiscriminately South American nations due to its narrow geographical focus. In September 2021, Trend Micro published a document documenting the activities of the Blind Eagle group.
The distribution of BitRAT malware is being done via spear-phishing campaigns primarily targeting Colombian entities, with a lesser focus on the targets of the following countries:-

Attack sequences are aborted if the email recipient is located outside Colombia, and Migración Colombia’s official website is redirected to the victim.

A much more complex multi-stage process is employed instead of a simple drop of RAT malware in this attack, which exploits the legitimate mshta.exe binary rather than dropping a RAT. This is done by executing VBScript embedded inside an HTML file so that two Python scripts can be downloaded.
The two python scripts are listed below:-
APT groups like Blind Eagle are a strange breed of APT groups regarding attacks. The organization seems more interested in cybercrime and monetary gain than espionage, based on its toolset and routine operations.
