A hacker operating under the s3rverexe moniker has successfully targeted an Iranian engineering website, defacing its front page and posting the stolen data online.
Credited as a part of Anonymous's ongoing OpIran campaign, the attack was first announced on s3rverexe Twitter account on Wednesday.
The attack saw s3rverexe deface the site's front page, making it open to a message offering hugs before landing on a new page containing a picture of an Anon - the word used by Anonymous members to define themselves - wearing a Guy Fawkes mask.
As well as the defacement s3rverexe also published a portion of the data taken from the site's server in a post on Pastebin. Credited as a part of the collective's continuing OpIran, the operation is designed to voice Anonymous's support for Iranian protesters.
Running in tandem to the "Iranian Revolution" the operation has seen Anonymous hackers mount numerous attacks on government Web sites to "protest" authorities' and military agencies' treatment of the protesters.
"The people of Iran have the admiration of Anonymous and the entire world. We can see that you still suffer at the hands of those in power. Your former government has seized control and tries to silence you," read one of Anonymous OpIran statements.
"You have the right to free speech and to free press, the freedom to assemble and be safe in your person. You have the right to live free and without fear. As Labor Day dawns Anonymous stands with you."
The exact reason why the engineering site was targeted past its Iranian origin remains unclear.
