Just a couple of hours ago I started getting some very shady looking tweets like the below.
Malicious Tweet
The link in the post is abbreviated, but leads on to a site hosting some obfuscated JavaScript.
If this JavaScript is executed by the browser an unpleasant payload is delivered to the victim. So far we have seen both malicious PDF documents and executable files. These Trojans attempt to connect to additional locations to download further malware. TrendLabs are currently investigating, watch the blog for updates.
This latest Twitter malspam follows hot on the heels of the Gaza and FIFA spam run earlier this month.
Be careful where you click and make sure your security software is blocking those evil links.
