Expert: Worm spreading in many ways becoming an epidemic
The worm known as Kido, aka Conficker or Downadup, evolves to spread via removable devices and other means besides just exploiting a Windows vulnerability.
A worm that spreads via removable devices, network shares, and weak administrator passwords--in addition to exploiting a critical Windows vulnerability--is spreading so fast it is becoming an epidemic, a security researcher said on Thursday.
Newer variants have been configured to give the worm the ability to infect via other means to get onto the network, said Roel Schouwenberg, a senior antivirus researcher at Kaspersky Lab.
"The Kido authors are trying to get into these networks by infected removable devices and by using other Trojans to install Kido on a computer, which will then try to infect other machines on the local network," he said in an e-mail statement. The worm "is currently causing an epidemic."
An estimated 3.5 million computers are believed to be infected with the worm, ZDNet reports.
