The US Health Sector Cybersecurity Coordination Center (HC3) has issued a warning about the Trinity ransomware, a malicious software known for extorting cryptocurrency from its victims by threatening to leak sensitive data. 

This ransomware employs various attack methods, including phishing emails, malicious websites, and software vulnerabilities, to infiltrate victims’ systems.

Once installed, Trinity ransomware scans the infected computer for sensitive information, which it then transmits to the attackers. It also encrypts the victim’s files, rendering them inaccessible. 

Victims receive a ransom note demanding payment in cryptocurrency in exchange for a decryption key, with a strict 24-hour deadline to comply or risk having their data leaked or sold. 

To be specific, the HC3 report stated: “It [Trinity ransomware] encrypts the victim’s files using a robust encryption algorithm, rendering them unusable without the correct decryption key. The ransomware typically appends the “.trinitylock” file extension to the affected files, making it clear which ones have been compromised.” 

HC3 highlighted that Trinity ransomware specifically targets critical infrastructure, such as healthcare providers. 

The agency reported that at least seven organizations have been affected, including one healthcare entity in the United States.

According to the report, there are currently no known decryption tools available for this ransomware, leaving victims with limited options to recover their data.
