A pro-Palestinian hacktivist group 'KDMS Team', who recently managed to briefly hijack the Metasploit website of security firm Rapid7 and become popular after Hacking World's largest Web Hosting Network Leaseweb website and antivirus vendors AVG, Avira as well as mobile messaging service WhatsApp's websites.
Now even I have to say that - Security is just an Illusion, because just now the group aligned with Anonymous has successfully hijacked another two Antivirus firm website - ESET and Bitdefender.
The KDMS Team successfully changed the DNS records of both sites to redirect people to a website playing the Palestinian national anthem and displaying a political message under the title "You Got Pwned".
Message posted on Bitdefender and Eset website says:
Both affected domains are registered from REGISTER.COM, INC. by companies, which is also a domain registrar for Metasploit website -- was hijacked yesterday via a spoofed change request faxed to Register.com. But the technical details on how hackers managed to hijack the ESET and Bitdefender website is not yet available, we are in contact with hackers.. Will update the article in a few hours. Stay Tuned !
