CyberZeist, the former UGNazi hacker, has joined the Anonymous movement and his first target has been the G4S, one of UK’s largest security companies, and the one WikiLeaks appoints as being responsible for “tagging” Julian Assange.
“Responsible for security services, managing detention centers, prisons, and 675 court and police station holding cells, G4S have also just been granted the £100 million contract for providing 10,000 security guards for the upcoming Olympics,” said the hacker regarding the company.
“Whilst G4S still seem to be government favorites, their record is far from spotless. The firm lost their previous 'forcible deportation' contract last September after receiving 773 complaints of abuse – both verbal and physical,” he added.
He also accuses G4S of being involved in the death of an Angolan citizen.
“The final straw came with the death of Jimmy Mubenga in October 2010, an Angolan asylum seeker who died as a result of his forced deportation by G4S guards. Two of the guards are on bail facing criminal charges, whilst G4S is still waiting to hear whether they are to face corporate manslaughter charges.”
The hacker claims to have gained access not only to the company’s main domain, g4s.com, but also its entire list of subdomains.
Besides server and DNS information, CyberZeist leaked around 400 user record sets comprising usernames – represented by email addresses -, and unsalted MD5 password hashes obtained from various subdomains.
“With this release I (CyberZeist) am now joining the Anonymous force to fight against the evil and Corrupt government and corporations,” the hacker concluded.
A few days ago, the same hacker took credit for leaking a number of 250 account details that belonged to federal employees.
Reportedly, he had used a spear phishing attack to obtain the information.
We have reached out to G4S, but at press time, they hadn't responded to our request for comment. We will return with more information as soon as it becomes available.
Update. G4S representatives have responded to out inquiry. The incident is currently being investigated.
Update2. G4S has provided an official statement regarding the hacker's claims.
“We have carried out a full investigation this morning into claims that G4S information systems have been hacked and we have found no evidence of any breach of security. However we take the security of our data sources very seriously and we are continuing to run a thorough check of all our systems,” a G4S representative told Softpedia.
