Twitter Limits Malware Links

Heres some great news about micro-blogging site Twitter that I think many people had been waiting months to hear –

The popular social site has now begun filtering links that lead to well-known malware sites.

This change was noted by security researchers on Monday but thus far I have not seen any official confirmation from Twitter themselves.


The new tactic has been put into place in order to prevent users of the service from accidentally finding themselves on sites that contain malware or other suspect programs or exploits.

Twitter has probably been pushed into taking such action because of a number of attacks which have targeted the site recently.

For example –

– to name just a few.

Part of the problem on Twitter is, ironically, the limit of 140 characters allowed for each message.

This has led to the widespread use of URL shortening services in order to save valuable character spaces but also allows malicious links to be disguised.

Twitter messages (which can be no longer than 140 characters) makes it easy to hide the true destination of links.

Costin Raiu, a security researcher at Kaspersky Lab, has suggested that Twitter is using Google’s Safe Browsing API, saying “It won’t catch everything but is definitively a step forward.”

  1. Didn’t stop the recent ddos attack did it!!!!!

  2. Good man Stu, very sensible.

  3. I don’t know for sure but I have read that too.

  4. I never click on links that have been shortened or hidden in any way. It is far too risky.

  5. I read somewhere that the security measures dont work too well, is that true?
