Kaspersky Lab has developed a tool for identifying malicious shortened weblinks in tweets posted on the Twitter microblogging service.
More than a quarter of tweets posted on Twitter contain links, many of which are shortened using services like bit.ly and myloc.me.
Although Twitter does filter for malicious links, security experts have warned that shortened links are not always blocked.
The danger is that shortened links obscure the destination and anyone clicking on these links could connect unwittingly to a malicious website.
The "Krab Krawler" tool by Kaspersky Lab supports the virus analysts in the labs to detect attacks over Twitter by analysing the millions of tweets.
"We are scanning nearly 500,000 new unique links that appear in Twitter posts every day", said Costin Raiu, said chief security expert at Kaspersky Lab.
According to Costin Raiu, up to 2% of the links scanned are connected to malware of some kind. These links will be identified and blocked for users of Kaspersky products.
