Many users claim that their system security tools flag the cryptfg.exe process as a malicious application that is associated with a variant of the Trojan.PWS.Zassan program, which is a family of Trojans reported to be embedded with password-stealing functionalities. This family of Trojans are known to infect unprotected Windows-based systems with unencrypted TCP/IP network ports, outdated OS security certificates and an unsecured Windows System Registry. These users state that the cryptfg.exe malware is capable of creating and injecting keys and entries into the unsecured Windows System Registry of the unprotected computer upon its successful placement and activation in the system, and these registry strings are said to allow the cryptfg.exe malware to automatically initialize during system startup and operate as a hidden background process during system runtime. This enables the cryptfg.exe malware to secretly gather private user details like passwords, email and IM account credentials, Internet surfing information and online banking transaction data from the infected system and its Web browsers, and unprotected Windows-based computers with missing or outdated OS security certificates are especially prone to these malicious functionalities. These users claim that the cryptfg.exe malware, once it has collected these details, then finds unencrypted TCP/IP network ports that it can exploit and use to initiate contact with predesignated remote servers that are managed by the authors of the cryptfg.exe malware. Upon establishing data transmission and communication lines with these remote servers, the cryptfg.exe malware is said to upload the data it has collected from the infected system to these remote servers.
