Ex-Ashley Madison CTO Threatens Libel Suit

Last month, KrebsOnSecurity posted an exclusive story about emails leaked from AshleyMadison that suggested the company’s former chief technology officer Raja Bhatia hacked into a rival firm in 2012. Now, an attorney for the former executive is threatening a libel lawsuit against this author unless the story is retracted.

According to Bhatia’s attorney, the part of the story they consider defamatory has to do with the headline of the piece, and this bit:

“A review of those missives shows that on at least one occasion, a former company executive hacked another dating website, exfiltrating their entire user database. On Nov. 30, 2012, Raja Bhatia, the founding chief technology officer of AshleyMadison.com, sent a message to Biderman notifying his boss of a security hole discovered in nerve.com, an American online magazine dedicated to sexual topics, relationships and culture.

At the time, nerve.com was experimenting with its own adult dating section, and Bhatia said he’d uncovered a way to download and manipulate the nerve.com user database.

“They did a very lousy job building their platform. I got their entire user base,” Bhatia told Biderman via email, including in the message a link to a Github archive with a sample of the database. “Also, I can turn any non paying user into a paying user, vice versa, compose messages between users, check unread stats, etc.”

Libel lawsuits in the United States are usually quite difficult and expensive for the plaintiff to win. But in Canada — where Bhatia’s attorney and AshleyMadison’s parent company Avid Life Media are headquartered — the libel laws are more complex for defendants. For example, according my consultation with a prominent Canadian digital media attorney, the onus there is on the accused to prove the disputed libelous claims are in fact true.

Nevertheless, I have no intention of posting a retraction or correcting any elements of this story. But I’m publishing a copy of the letter (PDF) from Bhatia’s lawyer in the likely event that other publications have also received libel and defamation threats from AshleyMadison and/or its current and former employees.

A story at Wired.com from Kim Zetter that ran shortly after my piece aired includes quite a few more colorful quotes from leaked emails Bhatia allegedly sent to AshMad CEO Noel Biderman.

Update, 11:49 a.m. ET: Added reference to Wired piece as the last sentence of this story.

Who Hacked Ashley Madison?

AshleyMadison.com, a site that helps married people cheat and whose slogan is “Life is Short, have an Affair,” recently put up a half million (Canadian) dollar bounty for information leading to the arrest and prosecution of the Impact Team — the name chosen by the hacker(s) who recently leaked data on more than 30 million Ashley Madison users. Here is the first of likely several posts examining individuals who appear to be closely connected to this attack.

zu-launchpad-july-20It was just past midnight on July 20, a few hours after I’d published an exclusive story about hackers breaking into AshleyMadison.com. I was getting ready to turn in for the evening when I spotted a re-tweet from a Twitter user named Thadeus Zu (@deuszu) who’d just posted a link to the same cache of data that had been confidentially shared with me by the Impact Team via the contact form on my site just hours earlier: It was a link to the proprietary source code for Ashley Madison’s service.

Initially, that tweet startled me because I couldn’t find any other sites online that were actually linking to that source code cache. I began looking through his past tweets and noticed some interesting messages, but soon enough other news events took precedence and I forgot about the tweet.

I revisited Zu’s tweet stream again this week after watching a press conference held by the Toronto Police (where Avid Life Media, the parent company of Ashley Madison, is based). The Toronto cops mostly recapped the timeline of known events in the hack, but they did add one new wrinkle: They said Avid Life employees first learned about the breach on July 12 (seven days before my initial story) when they came into work, turned on their computers and saw a threatening message from the Impact Team accompanied by the anthem “Thunderstruck” by Australian rock band AC/DC playing in the background.

After writing up a piece on the bounty offer, I went back and downloaded all five years’ worth of tweets from Thadeus Zu, a massively prolific Twitter user who typically tweets hundreds if not thousands of messages per month. Zu’s early years on Twitter are a catalog of simple hacks — commandeering unsecured routers, wireless cameras and printers — as well as many, many Web site defacements.

On the defacement front, Zu focused heavily on government Web sites in Asia, Europe and the United States, and in several cases even taunted his targets. On Aug. 4, 2012, he tweeted to KPN-CERT, a computer security incident response team in the Netherlands, to alert the group that he’d hacked their site. “Next time, it will be Thunderstruck. #ACDC” Zu wrote.

The day before, he’d compromised the Web site for the Australian Parliament, taunting lawmakers there with the tweet: “Parliament of Australia bit.ly/NPQdsP Oi! Oi! Oi!….T.N.T. Dynamite! Listen to ACDC here.”

I began to get very curious about whether there were any signs on or before July 19, 2015 that Zu was tweeting about ACDC in relation to the Ashley Madison hack. Sure enough: At 9:40 a.m., July 19, 2015 — nearly 12 hours before I would first be contacted by the Impact Team — we can see Zu is feverishly tweeting to several people about setting up “replication servers” to “get the show started.” Can you spot what’s interesting in the tabs on his browser in the screenshot he tweeted that morning?

Ten points if you noticed the Youtube.com tab showing that he’s listening to AC/DC’s “Thunderstruck.”

A week ago, the news media pounced on the Ashley Madison story once again, roughly 24 hours after the hackers made good on their threat to release the Ashley Madison user database. I went back and examined Zu’s tweet stream around that time and found he beat Wired.com, ArsTechnica.com and every other news media outlet by more than 24 hours with the Aug. 17 tweet, “Times up,” which linked to the Impact Team’s now infamous post listing the sites where anyone could download the stolen Ashley Madison user database.

ThadeusZu tweeted about the downloadable AshleyMadison data more than 24 hours before news outlets picked up on the cache.

Leaked AshleyMadison Emails Suggest Execs Hacked Competitors

Hacked online cheating service AshleyMadison.com is portraying itself as a victim of malicious cybercriminals, but leaked emails from the company’s CEO suggest that AshleyMadison’s top leadership hacked into a competing dating service in 2012.

Late last week, the Impact Team — the hacking group that has claimed responsibility for leaking personal data on more than 30 million AshleyMadison users — released a 30-gigabyte archive that it said were emails lifted from AshleyMadison CEO Noel Biderman.

A review of those missives shows that on at least one occasion, a former company executive hacked another dating website, exfiltrating their entire user database. On Nov. 30, 2012, Raja Bhatia, the founding chief technology officer of AshleyMadison.com, sent a message to Biderman notifying his boss of a security hole discovered in nerve.com, an American online magazine dedicated to sexual topics, relationships and culture.

At the time, nerve.com was experimenting with its own adult dating section, and Bhatia said he’d uncovered a way to download and manipulate the nerve.com user database.

“They did a very lousy job building their platform. I got their entire user base,” Bhatia told Biderman via email, including in the message a link to a Github archive with a sample of the database. “Also, I can turn any non paying user into a paying user, vice versa, compose messages between users, check unread stats, etc.”

Neither Bhatia nor Biderman could be immediately reached for comment. KrebsOnSecurity.com spoke with Bhatia last week after the Impact Team made good on its threat to release the Ashley Madison user database. At the time, Bhatia was downplaying the leak, saying that his team of investigators had found no signs that the dump of data was legitimate, and that it looked like a number of fake data dumps the company had seen in the weeks prior. Hours later, the leak had been roundly confirmed as legitimate by countless users on Twitter who were able to find their personal data in the cache of account information posted online.

The leaked Biderman emails show that a few months before Bhatia infiltrated Nerve.com, AshleyMadison’s parent firm — Avid Life Media — was approached with an offer to partner with and/or invest in the property. Email messages show that Bhatia initially was interested enough to offer at least $20 million for the company along with a second property called flirts.com, but that AshleyMadison ultimately declined to pursue a deal.

More than six months after Bhatia came to Biderman with revelations of the nerve.com security vulnerabilities, Biderman was set to meet with several representatives of the company. “Should I tell them of their security hole?” Biderman wrote to Bhatia, who doesn’t appear to have responded to that question via email.
