SecretForm.868

Description SecretForm.868

It is a dangerous nonmemory resident encrypted parasitic virus. It searches for .EXE files and writes itself to the end of the file. On November, 11th or depending on its internal counter the virus overwrites the host file with a trojan program, that program being executed displays:
My mother used to say
You're the boy that can enjoy invisibility
The pleasure is everlasting

Linux.Bliss.a

Description Linux.Bliss.a

This is nonmemory resident parasitic virus written in GNU C. It infects Linux OS only - infected files may be executed, and the virus may spread itself only under Linux. The virus searches for executable Linux files (ELF internal format) and infect them. While infecting, the virus shifts the file body down, write itself to the beginning of the file and append to the end of file the ID-text:
infected by bliss: 00010002:000045e4
It seems that the former hex number in these lines is a virus version, and the latter is the virus length - the virus lengths are 17892 and 18604 bytes.
When an infected file is run, the virus searches for not more than three non-infected files and infects them. If there are not any infected files in the current directory, the virus scans the system and infects the files in other directories. After infecting, the viruses return control to the host program, and it will work correctly.
Linux is an access-protected system; i.e., users and programs may access only files that they have permission to. The same goes for a virus - it may infect only the files and directories that are declared as "write-able" for the current username. If the current username has total access (system administrator), the virus will infect all the files on the computer.
The virus seems to be "under debugging," and while searching for files and infecting them, the virus displays several messages:
already infected
skipping, infected with same virus or a different type
replacing an older version
replacing ourselves with a newer version

infect() returning success
