This is a resident and stealth virus, infecting COM and EXE files when they are accessed.
The virus uses several levels of encryption with a 64-bit key to run a random data generation routine. It also uses anti-debugging and other tricks to hide its code.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
Hanko activates on July 7th at 7:07. At this time it displays this text and halts the computer:
My name is Monica. I'm your new virus. If you are a programmer, you can try to decode the author's info, that is encrypted somewhere in my body. The decryption routine is also implemented. You must only guess the key ... Good luck, friend. Now I stopped the computer. Press RESET, please.
There really is encrypted text in the middle of the virus code. This text is encrypted with 64-bit crypto-algorithm with an unknown key. After decryption this text reads:
Hi! You are really very good. So: My name is Michal Hanko, I'm from Czech Republic. I live in Letovice, Halasova street in Southern Moravia near Brno. My email is: email@example.com. Please, mail me that you've been succesful. Copyright (c) Majkl soft.
