- └─────────────────────────────┘
-
- Synonyms: 2080, 2086
-
- Date of Origin: March 10, 1988.
-
- Place of Origin: written by Sax Rohmer.
-
- Host Machine: PC compatibles.
-
- Host Files: Remains resident. Infects COM, EXE, overlay files.
-
- OnScreen Symptoms: You may see the message "You will hear from me again!"
-
- Increase in Size of Infected Files: 2086 bytes for COM files, 2080 bytes
- for EXE files.
-
- Nature of Damage: Affects system run-time operation. Corrupts COM and
- EXE files. Some versions corrupt overlay, SYS, and BIN files.
-
- Detected by: Scanv56+, F-Prot, IBM Scan, Pro-Scan.
-
- Removed by: CleanUp, Scan/D, or F-Prot.
-
- Derived from: Jerusalem.
-
- Scan Code: encrypted. You may be able to find the marker "sAXrEMHOr" in
- infected files. You can also search at offset 1EEH for FC B4 E1 CD 21 80
- FC E1 73 16.
-
- The virus occurs attached to the beginning of a COM file, or the end
- of an EXE file. It is a rewritten ("improved") version of the Jerusalem
- virus, and most of what is said for that virus applies here with the
- following changes:
-
- * The code to delete programs, slow down the machine, and display the
- black window has been removed, as has the dead area at the end of the
- virus and some sections of unused code.
-
- * The marker is now 'rEMHOr' (six bytes), and the preceeding 'sU' is
- now 'sAX' (Sax Rohmer - creator of Fu Manchu).
-
- * COM files now increase in length by 2086 bytes & EXE files 2080
- bytes. EXE files are now only infected once.
-
- * One in sixteen times on infection a timer is installed which runs for
- a random number of half-hours (maximum 7.5 hours). At the end of this
- time the message "The world will hear from me again!" is displayed in
- the center of the screen and the machine reboots. This message is
- also displayed every time Ctrl-Alt-Del is pressed on an infected
- machine, but the virus does not survive the reboot.
-
- * There is further code which activates on or after the first of August
- 1989. This monitors the keyboard buffer, and makes derogatory
- additions to the names of politicians (Thatcher, Reagan, Botha &
- Waldheim), censors out two four-letter words, and to "Fu Manchu" adds
- "virus 3/10/88 - latest in the new fun line!" All these additions go
- into the keyboard buffer, so their effect is not restricted to the
- monitor. All messages are encrypted.
-
- Some versions of this virus can infect overlay, SYS, and BIN files.
- It is still rare in the U.S.
