Security holes of Twitter has been exposed here again. An employee of Arbor Networks has recently discovered a botnet that uses Twitter as its command and control structure. The Twitter user “upd4t3” has been operating an infostealer operation using his account. The user posts status updates with links which contains commands or executables to download and run. The process is described at Arbor Networks blog.
According to the source, the account is under analysis by the Twitter security team. Hope they found ways to filter this kind of operations!
