  2. Agenda • Background • Timeline • Viral Damage • Propagation • Defense 2

  3. Background: • What is Conficker? • Computer virus (worm) • Effects Microsoft Windows Operating Systems • Propagates either through direct attack or via P2P • Capable of blocking/disabling some antivirus Everis Internal Presentation

  4. Timeline • Conficker Timeline • Nov. 21, 2008 • Conficker.A released – propagates using OS exploits • Dec. 29, 2008 • Conficker.B – propagates via OS exploits and password and fileshare exploits. Everis Internal Presentation

  5. Timeline Continued • Feb. 20, 2009 • Conficker.C Released • Mar. 4, 2009 • Conficker.D Released • Apr. 8, 2009 • Conficker.E Released Everis Internal Presentation

  6. Viral Damage • Infected System Impact • Conficker attempts to infect other systems • Uses MS Windows exploits (patched in 2008) • Contacts websites using algorithm-generated domain names for updates • Disable security-related software Everis Internal Presentation

  7. Propagation • Early versions of Conficker (A,B) propagated by attacks utilizing operating system exploits. • Later versions could reach out to upgrade systems with the earlier version, but would not seek to infect clean systems. Everis Internal Presentation

  8. Defensive • Pre-empt unregistered domains used for Conficker propagation • Redirect “evil” domains to controlled network honeypots to study Conficker operations. • Update security software / operating system to combat exploits and remove worm from systems. Everis Internal Presentation
