ESET unearths evidence linking Dridex to FriedEx ransomware. The malware was discovered by security researcher Michael Gillespie in July 2017. FriedEx is the codename under which ESET detects a ransomware previously known as Bit Paymer or BitPaymer. The ransomware made headlines in August when crooks used it to lock the IT systems of several Scottish hospitals. ESET claims there are countless of clues in FriedEx samples that link it to the DrideX banking trojan and Necurs spam botnet.
