Hackers affiliated with Teampoison Black-Hat group have attacked and defaced Croatia's Nato website in protest at the West's military intervention in Libya in 2011 and a long catalogue of Western interference in other countries.
The hacktivists have also dumped codes and logs from the Nato server on Pastebin as a proof of their attack. The defaced homepage carries a quotation from Nelson Mandela: "When a man is denied the right to live the life he believes in, he has no choice but to become an outlaw."
It also shows a video criticising controversial Nato-backed military and diplomatic action over the years, from the white phosphorus and depleted uranium dropped in Iraq to CIA involvement in the alleged killing of three anti-US presidents (Chile's Salvador Allende in 1973, Congo's Patrice Lumumba in 1961 and Iran's Mohammad Mosaddegh in 1967).
Teampoison announced the hack with a tweet. "Nato Croatia hacked by Teampoison nato.mvp.hr/index.asp | Zone-h Mirror: zone-h.org/archive/publis..."
"Dividing up a country when a genuine uprising is taking place just to build military bases and steal the countries' [sic] natural resources is wrong," reads a statement on the defaced homepage.
You were not needed in Libya, nor are you needed in Syria! You cover up the killings of innocent people in the name of democracy, companies like BAE Systems and BP Oil benefit from the blood that is being spilt by your hands!
"You spread propaganda through Rupert Murdoch's media machine to get support for these genocides.
The masses have allowed themselves to be dumbed down by the media. We have supported Nato terrorism against countries that disagree with Nato interest for way too long," it continues.
"We are all complicit in the murder of the innocent. It's time to make a stand!"
Born in 2009, Teampoison is affiliated with many anti-US and anti-Israel hacking teams such as Mujahideen Hacking Unit and ZCompany Hacking Crew (ZHC).
Some of their attacks include the hacking of the address book and other private data of former British prime minister Tony Blair and Operation Robin Hood, in which the team joined Anonymous to obtain credit card from websites that were donated to activists and charities all over the world.
Teampoison is a rival of LulzSec, an offshoot of the Anonymous group that publicly declared it was disbanding around nine months ago following almost 50 days of constant attacks.
In February, six of the group's most prominent members were arrested after the most prominent of them, known as Sabu, turned informant on his former colleagues.
Teampoison released in June 2011 the alleged personal details of various LulzSec members alongside information on the AnonOps IRC server, including IP addresses, and hashed passwords.
