Experts such as Symantec claimed the Nolor worm was a high risk, yet the number of infections are relatively low. This is down to many factors, and isn't necessaritly a reflection of the risk the worm poses, but is related to things such as people's waryness of email attachments following previous experiences and the constant nagging from corporation's security departments.
The Nolor worm (also known as Cailont) has been called a "garden variety" worm, as it speads using the conventional email address book method, but has the potential to spead rapidly – hence the high security warning issued initially.
A spokesman for Symantec has told ZDNet that "We're not seeing a great infection rate... the ratings are set (according to) the ability of the virus or worm has to send itself out". When asked about the trend of people not opening executable attachments they claimed that "It's a combination of technology and policy... most people know they shouldn't execute it. In that way we've almost won the policy war".
The worm is spead using a variety of styles to entice the reader to click the attachment, including "run File Attach to extract:BinladenSexy.jpg..." and "The Sexy story and 4 sexy picture of BINLADEN !".
