Hacker Maxney recently announced that Zifir, a fellow member of the Turkish Ajan Hacker Group, had breached and defaced the Austrian Web site for Mercedes-Benz, along with several subdomains (h/t HackRead).
While Maxney has claimed responsibility for several recent defacements by the group, this appears to the be first attributed to Zifir.
The defacement page was more explicit than other recent ones from the group, stating, "Hacked by TurkishAjan (since '08). Hacked by Zifir. Damn Israel. Bazen birseyleri degistirmek gerekir. Sometimes must be something."
According to HackRead, the hackers aren't releasing any data from the company.
