Malware has been observed that has been disguised to appear almost identical to legitimate scripts produced by the ionCube PHP encoder. When executed on a web server running PHP, the malware runs remotely-supplied code which allows a remote attacker access to and control over the system. Over 700 websites have been identified as infected.
The ionCube fakes are similar in appearance to legitimate ionCube files.
