This debug string shows us that the binary was compiled by a user account named “Wool3n.H4t,” and that the project behind this code was dubbed “CWoolger.” This malware is a keylogger, although from a technical point of view, it is not as advanced as its contemporaries. The malware also embedded some File Transfer Protocol (FTP) credentials of the attackers in clear text in the binary.
