SAN FRANCISCO, Aug 28 (Reuters) - Media companies, including the New York Times, Twitter and the Huffington Post, lost control of some of their websites Tuesday after hackers supporting the Syrian government breached the Australian Internet company that manages many major site addresses.
The Syrian Electronic Army (SEA), a hacker group that has attacked media organizations it considers hostile to Syrian President Bashar al-Assad, claimed credit for the Twitter and Huffington Post hacks in a series of Twitter messages.
Security experts said electronic records showed that NYTimes.com, the only site with an hours-long outage, redirected visitors to a server controlled by the Syrian group before it went dark.
New York Times Co spokeswoman Eileen Murphy tweeted the “issue is most likely the result of a malicious external attack,” based on an initial assessment.
The Huffington Post attack was limited to the blogging platform’s British web address. Twitter said the hack led to availability issues for 90 minutes but that no user information was compromised.
The attacks came as the Obama administration considers taking military action against the Syrian government, engaged in a civil war against rebels for more than two years.
In August, hackers promoting the Syrian Electronic Army targeted websites belonging to CNN, Time and the Washington Post by breaching a third party service used by those sites.
The SEA managed to gain control of the sites by penetrating MelbourneIT, an Australian Internet service provider that sells and manages domain names including Twitter.com and NYTimes.
The New York Times, which identified MelbourneIT as its domain name registrar and the main hacking victim, told employees not to send sensitive emails from corporate accounts.
MelbourneIT tracked the breach to an Indian Internet service provider, saying two staff members from one of their resellers opened a fake email seeking login details.
“The SEA went after the company specifically to create a high-profile event,” CEO Theo Hnarakis told Reuters. “This was quite a sophisticated attack.”
One staff member was the direct manager of the NYTimes domain along with other media companies and had the login and password information of the company in his email, which the hackers accessed.
Hnarakis confirmed that other media organizations were also attacked, but this proved unsuccessful as their customers used a secondary security measure known as a registry lock.
MelbourneIT said it restored the correct domain name settings, changed the password on the compromised account, and locked the records to prevent further alterations.
Twitter did not respond to requests for comment. In a blog post, the company said “it appears DNS (domain name system) records for various organizations were modified, including one of Twitter’s domains used for image serving, Twimg.com. Viewing of images and photos was sporadically impacted.”
Jaeson Schultz, a Cisco Systems researcher, said that in the authoritative records known as WHOIS the Syrian Electronic Army listed itself as the contact for all of Twitter.com, which would have given it the power to take the site offline or place its own content there.
“It seems that their message is redirecting people back to their own website for news about the SEA or about Syria,” Schultz said. “They don’t seem to be interested in infecting end users, which is a good thing.”
Hackers who successfully break into MelbourneIT’s systems could potentially redirect and intercept emails sent to addresses under certain domains, researchers said. And users of sites that do not begin with “https” could have been fooled into entering passwords that could have been captured, said Jaime Blasco, a researcher with security firm AlienVault.
Because MelbourneIT serves as the registrar for some of the best known domain names on the Internet, Tuesday’s breach could have had potentially catastrophic consequences.
“This could’ve been one of the biggest attacks we’ve ever seen, if they were more subtle and more efficient about it,” said HD Moore, the chief research officer at Rapid7, a cyber security firm. “They changed just a few sites, but if they had actually gone all out, they could’ve had most of the Internet watching them run the show.”
Media companies, largely ignored by hackers until 2011, have since been targeted by pranksters and suspected Chinese agents, as well as partisans in the Middle East. (Additional reporting by Michael Sin in Sydney; Editing by Michael Perry, Eric Walsh, Ron Popeski and Phil Berlowitz)
