Troj/GunBo-A is an information-stealing Trojan for the Windows platform.

When run Troj/GunBo-A attempts to steal user information pertaining to Softnyx's online game Gunbound.

Troj/GunBo-A will display a series of messages enquiring the user to key in confidential information and pretends to be an application hack for the online game Gunbound. The Trojan purports to have the ability to artificially hack Softnyx GB servers to allow the online character to gain "money."

Once the relevant user information has been gathered, Troj/GunBo-A will send this information to a remote email address via SMTP.
