What is Conficker
For those who don’t know about Conficker, Conficker (also known as Downadup and Kido) is a worm which in recent months using a security breach in the RPC service (which Microsoft settled in October last year) has infected more than 10 million computers around the world by using advanced malware techniques.When executed on a computer, Conficker disables a number of system services such as Windows Automatic Update, Windows Security Center, Windows Defender and Windows Error Reporting.
Experts say it is the worst infection since the SQL Slammer.The potential scale of infection is large because 30% of Windows computers do not have Windows patch released in October 2008 to block this vulnerability.
Symptoms of Conficker infection:
- Microsoft Windows services such as Automatic Updates, Windows Defender, and Error Reporting Services are automatically disabled.
- Domain controllers respond slowly to client requests.
