Cannot login to my wordpres account; pluggable.php error

I’m sorry to tell you, I believe you have been hacked. Fortunately you’ve been hacked by an incompetent hacker, who installed a plugin whose bugs revealed their presence.

I had the same problem, so I had a look at the source code reported in the warning. It was suspicious looking sourcecode with wierd looking redirects and what seemed to be intentionally obfuscated behavior (fair enough, php seems that way normally, but this was especially so).

I hate to make judgements based on nationality, but the presence of russian texts, and an attempt to redirect to a Russian webpage raised warning flags.

I checked the filestamps in the plugins folder and found a second folder “antisp” that was also created on the same date (feb 14’th in my case). I haven’t installed any plugins recently so I can reasonable conclude that a foreign entity introtuded these. I deleted the two folders (antisp and spamdetectvr) and my site functioned again.

Of course the first thing did when I realized what had happened was to change my admin password to something significantly more secure. Please take appropriate measures, and good luck. If you found anything more nefarious or competent, let me know.
