Spyware Information: Backdoor.Fraggle

This application is a worm. Unlike a virus, whose purpose is both to install itself on as many computers as possible and then perform some (probably damaging) action on them, worms are designed primarily to copy themselves and not to accomplish anything specific once copied. Worms can do a lot of damage to a network or even the Internet if they multiply fast enough, and they could be used by malicious software as a means to spread.

Research

  • Method of infection: Backdoor.Fraggle scans the network searching for weak passwords and attempts to copy itself to shared directories.
  • Advertising: None.
  • Browser degradation: As with any worm, the entire infected computer will experience performance degradation.
  • Privacy policy: None.
  • Security issues: Backdoor.Fraggle connects to remote IRC server ntupdater.wwwhost.biz and joins channel shabby123 with nick GW|nt-##### (where ##### is a random number). Backdoor.Fraggle then acts as an IRC bot and can perform many malicious actions (such as DDoS attacks, port scans, attempts to copy itself to other machines).
  • Stability issues: As with any worm, the entire infected computer may experience crashes or other errors.
