Washington: The website of the Swedish
prosecutor`s office pursuing WikiLeaks founder Julian Assange
has come under cyber attack in the latest salvo by his online
PandaLabs, the malware detection laboratory for computer
security firm Panda Security, said the prosecutor`s website,
aklagare.se, was brought down yesterday by members of the
"cyber hacktivist" group called "Anonymous."
Attempts by a news agency to connect to the aklagare.se website
around 5:00 pm (local time) were unsuccessful.
The attack on the Swedish prosecutor`s website came as
Assange was refused bail yesterday by a British judge over
charges of sex crimes in Sweden.
Sean-Paul Correll, a threat researcher at PandaLabs, said
the group called Anonymous launched the attack on the Swedish
prosecutor`s website and others against PayPal and the Swiss
Post Office bank.
PayPal blocked financial transfers to WikiLeaks last week
while the Swiss Post Office bank closed accounts held by
Assange, whose release of secret US diplomatic cables has
sparked an international furor.
PostFinance.ch, the website of the Swiss Post Office
bank, was unavailable yesterday after coming under cyber
PayPal`s official blog, ThePayPalBlog.com, came under
distributed denial of service, or DDoS, attack on Saturday and
went down briefly but was back up yesterday.
In a classic DDoS attack, a "botnet" of zombie computers,
machines infected with viruses, are commanded to
simultaneously visit a website, overwhelming its servers,
slowing service or knocking it offline completely.
Correll, the PandaLabs researcher, said on his blog that
the Swedish prosecutor`s website went down "instantaneously"
with "over 500 computers in the voluntary botnet attacking the
site all at once."
Correll said the website used by Anonomyos, anonops.net,
has been the target of cyber attacks as well and went down
WikiLeaks itself has been under cyber attack since
Assange began releasing the US documents last week, forcing it
to change addresses and servers.
