Tracking Conficker: So far, it's a snoozer [Update]
It's already April 1 in Asia, where the plurality of infected Conficker PCs are apparently located. Early reports on the Windows computer worm, which was supposed to start looking at 500 Internet domains for new instructions, show that not much is happening initially.
Context & Ripple Effects
A new Conficker variant identified in March had already shifted concern from self-propagation to potential damage on infected machines. Coverage ahead of April 1 focused on its planned use of a large rotating set of Internet domains for instructions.
The initially quiet domain-contact activity narrows the immediate alarm but does not remove the remediation problem: confirmed malicious results for Downad and Conficker removal searches put people attempting cleanup at risk.
First-order effects
- Conficker-infected Windows PCs have not initially received the expected new instructions through the anticipated domain-query mechanism, limiting immediate command-and-control activity.
- Windows users seeking Conficker removal tools face a separate, active exposure from poisoned search results masquerading as cleanup help.
Second-order effects
- Security responders can use the lack of initial domain activity to concentrate on identifying and cleaning infections, while also warning users away from untrusted removal downloads.
- The poisoned-search tactic turns public attention around Conficker into an attack surface, making search-result integrity part of the response rather than merely a route to support information.
Third-order effects
- If malware operators can exploit both infected machines and the channels used to remediate them, endpoint defense shifts from blocking a worm alone to securing the entire recovery path.
- The episode points toward a security model in which command-and-control monitoring and trusted remediation distribution must operate together, especially for widely distributed Windows infections.
The trend: Malware response is becoming an ecosystem problem, combining botnet monitoring with protection of the search and software channels victims use to recover.
