Rise of Darknet Stokes Fear of The Insider

With the proliferation of shadowy black markets on the so-called “darknet” — hidden crime bazaars that can only be accessed through special software that obscures one’s true location online — it has never been easier for disgruntled employees to harm their current or former employer. At least, this is the fear driving a growing stable of companies seeking technical solutions to detect would-be insiders.

Avivah Litan, a fraud analyst with Gartner Inc., says she’s been inundated recently with calls from organizations asking what they can do to counter the following scenario: A disaffected or disgruntled employee creates a persona on a darknet market and offers to sell his company’s intellectual property or access to his employer’s network.

Litan said a year ago she might have received one such inquiry a month; now Litan says she’s getting multiple calls a week, often from companies that are in a panic.

“I’m getting calls from lots of big companies, including manufacturers, banks, pharmaceutical firms and retailers,” she said. “A year ago, no one wanted to say whether they had or were seriously worried about insiders, but that’s changing.”

Insiders don't have to be smart or sophisticated to be dangerous.

Insiders don’t have to be smart or sophisticated to be dangerous, as this darknet forum discussion thread illustrates.

Some companies with tremendous investments in intellectual property — particularly pharmaceutical and healthcare firms — are working with law enforcement or paying security firms to monitor and track actors on the darknet that promise access to specific data or organizations, Litan said.

Bidding for Breaches, Redefining Targeted Attacks

A growing community of private and highly-vetted cybercrime forums is redefining the very meaning of “targeted attacks.” These bid-and-ask forums match crooks who are looking for access to specific data, resources or systems within major corporations with hired muscle who are up to the task or who already have access to those resources.

A good example of this until recently could be found at a secretive online forum called “Enigma,” a now-defunct community that was built as kind of eBay for data breach targets. Vetted users on Enigma were either bidders or buyers — posting requests for data from or access to specific corporate targets, or answering such requests with a bid to provide the requested data. The forum, operating on the open Web for months until recently, was apparently scuttled when the forum administrators (rightly) feared that the community had been infiltrated by spies.

The screen shot below shows several bids on Enigma from March through June 2015, requesting data and services related to HSBC UK, Citibank, Air Berlin and Bank of America:

One particularly active member, shown in the screen shot above and the one below using the nickname “Demander,” posts on Jan. 10, 2015 that he is looking for credentials from Cisco and that the request is urgent (it’s unclear from the posting whether he’s looking for access to Cisco Corp. or simply to a specific Cisco router). Demander also was searching for services related to Bank of America ATMs and unspecified data or services from Wells Fargo.

Much of the information about Enigma comes from Noam Jolles, a senior intelligence expert at Diskin Advanced Technologies. The employees at Jolles’ firm are all former members of Shin Bet, a.k.a. the Israel Security Agency/General Security Service — Israel’s counterespionage and counterterrorism agency, and similar to the British MI5 or the American FBI. The firm’s namesake comes from its founder, Yuval Diskin, who headed Shin Bet from 2005 to 2011.

“On Enigma, members post a bid and call on people to attack certain targets or that they are looking for certain databases for which they are willing to pay,” Jolles said. “And people are answering it and offering their merchandise.”

Those bids can take many forms, Jolles said, from requests to commit a specific cyberattack to bids for access to certain Web servers or internal corporate networks.

“I even saw bids regarding names of people who could serve as insiders,” she said. “Lists of people who might be susceptible to being recruited or extorted.”

Many experts believe the breach that exposed tens of millions user accounts at — an infidelity site that promises to hook up cheating spouses — originated from or was at least assisted by an insider at the company. Interestingly, on June 25, 2015 — three weeks before news of the breach broke — a member on a related secret data-trading forum called the “Gentlemen’s Club” solicits “data and service” related to AshleyMadison, saying “Don’t waste time if you don’t know what I’m talking about. Big job opportunity.”

Cybercrime forums like Enigma vet new users and require non-refundable deposits of virtual currency (such as Bitcoin). More importantly, they have strict rules: If the forum administrators notice you’re not trading with others on the forum, you’ll soon be expelled from the community. This policy means that users who are not actively involved in illicit activities — such as buying or selling access to hacked resources — aren’t allowed to remain on the board for long.
