CiphBit Ransomware

CiphBit Ransomware

September 9, 2025

CiphBit ransomware, first discovered in 2020, continues to pose a significant risk due to its uncrackable encryption and persistence in victims’ networks. Two notable incidents include the attack on Travelex currency exchange in January 2020 and the crippling of hospital systems in the Universal Health Services network in the U.S in September 2020. This ransomware variant commonly uses malicious emails and exploits to infiltrate targeted Windows operating systems. Users who fall victim to CiphBit are left with .ciph file extensions and a ransom note demanding payment in cryptocurrency.
