Conficker hasn’t gone anywhere
The Conficker/Downadup worm, which first surfaced in 2008, has infected thousands of business networks. Unpatched computers are most at risk of infection, with Conficker exploiting these computers by overcoming weak passwords and propagating itself through unprotected USB storage devices.
Conficker, despite its age, continues to be detected by anti-malware systems. It compromised computers for business, government, and home uses across the world. It infected and exploited millions of Windows devices at its height, and remains pervasive. Its trick: it exploited an old, unpatched vulnerability to crack passwords. Once it was in, Conficker would then use the infected computer to distribute spam and other malicious activities.
To this day, Conficker is still lurking out there on the web, spreading through exploits, file sharing, and removable media.
