[edit] Description
Brontok Virus came from Indonesia. When Brontok is first run, it copies itself to the user's application data directory. It then sets itself to start up with Windows, by creating a registry entry in the HKLM\Software\Microsoft\Windows\CurrentVersion\Run registry key. It disables the Windows Registry Editor and modifies Windows Explorer settings. It removes the option of "Folder Options" in the Tools menu so that the hidden files, where it is concealed, are not easily accessible to the user. It also turns off Windows firewall. In some variants, when a window is found containing certain strings in the window title, the computer reboots. Using its own mailing engine, it sends itself to email addresses it finds on the computer, even faking the own user's email address as the sender. The computer also restarts when trying to open MS Dos in Windows and Downloading Files from the Internet. It also pop ups an Internet browser which is located in the my pictures folder.
[edit] Origin
The virus/email itself contains a message in Indonesian (and some broken English). When translated, this reads:
BRONTOK. A [By: H [REMOVED] Community] -- stop the collapse in this country -- 1. Try the Hoodlums, the Smugglers, the Bribers, the gamblers, & drugs Port (Send to "Nusakambangan") -- 2.Stop Free sex, Abortion, & Prostitution 3.Stop (pollution of sea & the river), the burning of the forest & the wild hunting. 4.SAY NO TO DRUGS!!! -- DOOMSDAY is CLOSE -- Terinspirasi by: the Brontok Eagle (Spizaetus Cirrhatus) that is almost extinct [By: H [REMOVED] unity --
It also contains a JavaScript pop-up.
The worm also carried out a ping flood attack on two websites: israel.gov.il and playboy.com. This virus may be an example of Hacktivism.
