Symantec Intelligence Report
Symantec Corp recently announced the results of the October 201 I Symantec Intelligence Report. This month's analysis reveals that for the first time, spammers have established a genuine URL shortening service that is publically available and will generate real shortened links. These have so far only been found in spam emails. October Intelligence reports shows spammers using open source URL shortening scripts to operate malicious sites http://bit.ly/o27jGg
During 2010, 92% of spam emails contained URLs and the use of shortened links makes it harder for traditional anti-spam countermeasures to block the messages based on fingerprinting the URL. Legitimate services are much quicker to respond to abuse, and spammers are preying on the knowledge that many people are familiar with shortened links through their use in social media, and have developed a false sense of security about them.
Symantec Intelligence reported earlier this year that spammers had set up their own URL shortening services to better conceal their spam sites and make them harder to block. This month's analysis indicates that a spam gang with at least 80 URL shortening sites have been operating, all using a similar naming pattern, and used the.info top-level domain. However, unlike the URL shortening sites uncovered earlier this year, these sites are effectively public URL shortening sites. Anyone can create a shortened URL on these sites; the form to do so is also publically available.
"Spammers are using a free, open source URL shortening scripts to operate these sites. After creating many shortened URLs with their own service, the spammers then send spam including these URLs. These particular spammers use subjects designed to attract attention, like 'It's a long time since I saw you last!,' 'It's a good thing you came' and so on. This is a common social engineering tactic, and is designed to arouse curiosity, particularly if they have a false sense of security around the safety of shortened links," said Paul Wood, Senior Intelligence Analyst, Symantec.cloud.
"It is possible that spammers are setting up their own URL shortening sites since legitimate URL shortening sites, which have long suffered with abuse, have slightly improved their detection of spam and other malicious URLs." www.symantec.com.
