The dark web is an increasingly lawless place where cybercriminals trade hacks, passwords and stolen corporate data.
Data stolen from Yahoo several years ago is openly for sale on its forums and even the criminals lurking there are open to attack. To shore up their own cyber defences, CIOs need to take a more proactive approach to monitoring threats in its hidden depths.
The so called dark web, buried in the deep web, utilizes a different protocol and is not indexed by mainstream search engines. Users go about their business anonymously, their locations protected by encryption and a host of privacy features baked into the free and readily-available Tor browser, which is the most common way of accessing it. This makes it a paradise for cybercriminals.
Exposing these illicit transactions is almost impossible as many take place in invitation-only forums and authenticated to stop anyone tracking them.
But it seems that even the dark web is not invincible when it comes to vulnerabilities. The recent hack of Freedom Hosting II, the largest host of dark websites, shows that there are holes in the deepest abyss of the internet.
In addition, Alphabay, reputably the biggest dark web market place, recently issued a statement on Pastebin confirming that it had rewarded a hacker after they had found bugs that had enabled them to steal 218,000 unencrypted messages between buyers and sellers. This hack highlights the scale of business being done on the dark web and underlines why CIOs need to understand its dangers and minimize their organizations’ exposure.
It could be argued that the these vulnerabilities in the dark web makes it easier for ethical hackers to get a better view of what data sits there, while making the dark web a more dangerous place for cybercriminals to play. In this case stolen data, which included names and addresses, were handed over to law enforcement agencies. But only a minute percentage of stolen data is handled responsibly.
Take Yahoo, for example. Data from a breach involving one billion Yahoo accounts back in 2013, which the company only went public about last year, is still being openly sold on the dark web. The stolen data for sale includes personal data including names and birth dates.
CIOs are beginning to understand that a more proactive approach must be taking to scanning the dark web for cyber threats that can be averted. But due to the make-up of dealings and the trust required between buyers and sellers on the dark web, human intelligence is essential in monitoring the dark web - automated tools alone are not enough.
However, monitoring the dark web is an enormous task. It requires a global team of cyber experts to analyze massive volumes of data and linguists who can impersonate cybercriminals to gain their trust.
Threat monitoring the dark web gives CIOs intelligence that can act as an early warning system. It can uncover, for example, if cybercriminals are planning an attack, so the organization can pre-empt a breach and take immediate action to protect their digital identities and servers.
Insiders lurk in the deep
One of the biggest threats of the dark web is that dissatisfied employees can use it to sell their services to cybercriminals, according to Avivah Litan, VP distinguished analyst at Gartner. A report by RedOwl and InSights, claims that the active recruitment of insiders in the dark web is growing fast, with insider outreach going up nearly 50 percent from 2015 to 2016.
The report maintains that the dark web has created an active market for employees to easily monetize insider access. It says that sophisticated cybercriminals are using the dark web to find and engage insiders to help them get malware over organization’s perimeter security and trigger it.
Gartner’s Litan says that its clients blame the ease in which discontented employees can download the Tor browser and log into the dark web. Litan accepts that insider threats are a sensitive issue and that companies do not want pry and encroach on employee privacy, but at the same time must protect their business assets. “Organizations must be the judge of how high their risks are and how far they need to go fighting it,” she says.
The RedOwl and Insights report recommends that enterprises “create, train and enforce consistent security policies while protecting employee privacy”. This includes making sure employees and contractors understand penalties involved in insider action on the dark web.
The darkest can shed the most light
The dark web provides a rich source of cyber threat intelligence for any CIO looking to bolster their cyber defenses. By monitoring its inner workings, organizations can find out what data or IP may has been stolen, or leaked by insiders to use against them.
Tor, however, has made no secret of the fact it is doing more to safeguard its users this year, making the dark web even more difficult to penetrate. This will include sandboxing Tor at the application level and investigating the use of quantum computing.
There isn’t an organization out there who can claim it will never be compromised. Threat detection is paramount. If CIOs know what they are up against, they can take the appropriate steps to protect their organizations. Having an ear to what is being discussed in the chambers of the dark web is invaluable in the war against cybercrime.
