Fidel

Fidel is a form of malware, also known as Fidel ransomware or Colddraw, which is designed to exploit and damage computer systems. It infiltrates systems through suspicious downloads, emails, or websites, often unbeknownst to the user. Once inside, it can steal personal information, disrupt operations, or hold data hostage for ransom. The malware is identified by a unique marker placed at the beginning of all encrypted files. The group behind this malware has been known to change names several times since its inception. The operators of Fidel maintain a ".onion" webpage located on the dark web, accessible via the TOR network. This site is heavily themed with Cuban nationalistic styling, featuring images of the Cuban flag, former leader Fidel Castro, and Che Guevara, a major figure of the Cuban Revolution. The use of these images and the name "Fidel" suggest an attempt to align the malware's identity with symbols of rebellion and resistance, possibly as a psychological tactic to intimidate victims or confuse investigators. Interestingly, the term "Fidel" also relates to the late Cuban leader Fidel Castro. A book about Castro's visit to Vietnam was launched in Cuba, marking the 50th anniversary of his historic trip. The book, published in both Vietnamese and Spanish, underscores Castro's special affection for Vietnam and its people, as well as his solidarity with their struggle. However, there is no direct link between the malware and Castro's legacy, aside from the shared name. The choice of the name "Fidel" for the malware appears to be more related to the symbolic power associated with Castro's image than any specific connection to his actions or ideology.
