A message posted to Operation Payback’sTwitter feed in December (WEB HOST INDUSTRY REVIEW) — The FBI said Thursday it has attained more than 40 search warrants across the US, seeking the pro-WikiLeaks hackers responsible for launching retaliation attacks against companies that suspended services to the whistle-blower website. The move follows last month’s raid of Texas-based web host , Tailor Made Services, where FBI confiscated a computer believed to be used in the DDoS attacks against PayPal. Meanwhile, UK authorities arrested five men Thursday morning in connection with the DDoS attacks on Visa, Mastercard, Paypal and Amazon in mid-December .
