Hackers associated with the hacktivist collective Anonymous say they have leaked gigabytes of data from Epik, a web host and domain registrar that provides services to far-right sites like Gab, Parler and 8chan, which found refuge in Epik after they were booted from mainstream platforms.
In a statement attached to a torrent file of the dumped data this week, the group said the 180 gigabytes amounts to a "decade's worth" of company data, including "all that's needed to trace actual ownership and management" of the company. The group claimed to have customer payment histories, domain purchases and transfers, and passwords, credentials and employee mailboxes. The cache of stolen data also contains files from the company's internal web servers, and databases that contain customer records for domains that are registered with Epik.
The hackers did not say how they obtained the breached data or when the hack took place, but timestamps on the most recent files suggest the hack likely happened in late February.
TechCrunch has since learned that Epik was warned of a critical security flaw weeks before its breach.
Security researcher Corben Leo contacted Epik's chief executive Monster over LinkedIn in January about a security vulnerability on the web host's website. Leo asked if the company had a bug bounty or a way to report the vulnerability. LinkedIn showed Monster had read the message but did not respond.
Leo told TechCrunch that a library used on Epik's WHOIS page for generating PDF reports of public domain records had a decade-old vulnerability that allowed anyone to remotely run code directly on the internal server without any authentication, such as a company password.
"You could just paste this [line of code] in there and execute any command on their servers," Leo told TechCrunch.
Leo ran a proof-of-concept command from the public-facing WHOIS page to ask the server to display its username, which confirmed that code could run on Epik's internal server, but he did not test to see what access the server had, as doing so would be illegal.
It's not known if the Anonymous hacktivists used the same vulnerability that Leo discovered. (Part of the stolen cache also includes folders relating to Epik's WHOIS system, but the hacktivists left no contact information and could not be reached for comment.) But Leo contends that if a hacker exploited the same vulnerability and the server had access to other servers, databases or systems on the network, that access could have allowed access to the kind of data stolen from Epik's internal network in February.
"I am really guessing that’s how they got owned," Leo told TechCrunch, who confirmed that the flaw has since been fixed.
Monster confirmed he received Leo's message on LinkedIn, but did not answer our questions about the breach or say when the vulnerability was patched. "We get bounty hunters pitching their services. I probably just thought it was one of those," said Monster. "I am not sure if I actioned it. Do you answer all your LinkedIn spams?"
