Amazon lost control of a small portion of its cloud services for two hours on Tuesday morning when hackers exploited a known Internet-protocol weakness that allowed them to redirect traffic to rogue destinations. By subverting Amazon's domain-resolution service, the attackers masqueraded as cryptocurrency website MyEtherWallet.com and stole about $150,000 in digital coins from unwitting end users. They may have targeted other Amazon customers as well.
The incident, which started around 6 AM California time, hijacked roughly 1,300 IP addresses, Oracle-owned Internet Intelligence said on Twitter. The malicious redirection was caused by fraudulent routes that were announced by Columbus, Ohio-based eNet, a large Internet service provider that is referred to as autonomous system 10297. Once in place, the eNet announcement caused Hurricane Electric and possibly other peers of eNet to send traffic over the same unauthorized routes. Amazon and eNet officials didn't immediately respond to a request to comment.
