| Alias: | --- |
| Strain: | CompuPhagozyte Virus strain |
| detected when: | --- |
| where: | --- |
| Classification: | Link Virus (directory type), non-resident |
| Length: | 1.Length on storage medium: 1452 byte 2.Length in RAM: 1452 byte |
Preconditions | |
| Operating System(s): | AMIGA-OS |
| Version/Release: | 1.2/all, 1.3/all, 2.0/all, 3.0/all |
| Computer model(s): | All AMIGA models |
| Caroname: | Compuphagozyte.1_1452 |
Attributes | |
| Easy identification: | The following text appears in infected files: "The CompuPhagozyte has attached to your system ! Wait for much more better virus on other systems, too! The CompuPhagozyte in 9.91 by The Emperor Of Trillion Bytes ! Virus-Checker V4.0 by Michael Ortmanns" |
Type of Infection: | System infection: overwriting the file ":c/virus-checker" if this exists. |
| Infection Technique: | |
| Infection Trigger: | Inserting a disk-like medium while virus program is active. |
| Storage Media affected: | All disk-like media |
| Interrupts hooked: | None |
| Stealth: | |
| Tunneling/Selfprot: | |
| Oligo/Polymorphism: | |
| Encoding Method: | |
| Damage: | 1) Writing file ":c/virus-checker" on disk. 2) Potentially destroying floppy disk structure (see Particularities). |
| Damage Trigger: | Upon inserting a disk-like medium. |
| Particularities: | 1) Virus pretends to be "virus-checker 4.0". Virus' infectivity is small as it always tries to write to current directory. 2) If for some reason file ":c/virus-checker" could not be written to disk, some obscure hardware banging routine is called which seems to destroy disk structure (of floppy disk only). 3) If real ":c/Virus-checker" exists, it is corrupted and shortened to 1452 byte (poten- tially due to an error of AmigaDOS-Write routine; cause not fully verified) |
