Cryzip.A is a Trojan that compresses in password-protected ZIP format all the files with any of the following extensions: ARH, ARJ (files compressed with ARJ), ASM, BAS, C, CDR, CGI, CHM, CPP, DB, DB1, DB2, DBF, DBT, DBX, DOC (Word documents), DPR, DSW, FRM, FRT, FRX, GTD, GZ, GZIP, JPG, KEY, KWM, LST, MAN, MDB (Access databases), MMF, MO, OLD, P12, PAK, PAS, PDF, PEM, PGP, PL, PWL, PWM, RAR (files compressed with WinRAR), RTF, SAFE, TAR, TXT (text files), XLS (Excel spreadsheets), XML and ZIP (files compressed with WinZip).
Users will not be able to open those files until they enter the password. Cryzip.A creates a text file with instructions about how to pay for the password using e-gold.
If you have been affected by this Trojan, the password to decompress the files is the following:
Cryzip.A does not spread automatically by its own means. It needs an attacking user's intervention in order to reach the affected computer.
However, if you cannot find any files with the extensions mentioned above and instead of them, there are files whose names contain the text string _CRYPT_.ZIP, your computer is likely to have been affected by Cryzip.A.
