How it works?

Shylock is found to be more sophisticated and efficient than any banking malware. According to an analysis on Caphaw published by by ESET security researcher Aleksandr Matrosov, “This is one of the few pieces of malware that can automatically steal money when the user is actively accessing his banking account.” The research also revealed other malware associated with Shylock/Caphaw are Gataka, Carberp, Tinba and Ranbyus.

Thus, Shylock malware is able to resist and restore after the antivirus scanning and cleaning procedure occurs.

Though it is not yet clear how Shylock/Caphaw malware is reaching banking customers, researchers at Zscaler ThreatLabZ security suspected that “it is more than likely arriving as part of an exploit kit [homing] in on vulnerable versions of Java.” Devices infected with Shylock/Caphaw malware are found to run Windows XP and a Java 6 version as that version consists of multiple exploitable and vulnerabilities.
