Journalist William Langewiesche at Vanity Fair presents the storied career of a hacker-turned-security expert, whom he pseudonymously calls Opsec, in the extensive article, “Welcome to the Dark Net, a Wilderness Where Invisible World Wars are Fought and Hackers Roam Free.” The engaging piece chronicles the rise of the Dark Web alongside Opsec’s cyber adventures, which began when he was but a child in the late ’80s. It also clearly explains how some things work on and around the Dark Web, and defines some jargon. I would recommend this article as a clear and entertaining introduction to the subject, so readers may want to check out the whole thing.
Meanwhile, I found this tidbit about a recent botnet attack interesting. For background, Opsec now works for a large, online entertainment company. Langewiesche describes an intrusion the security expert recently found into that company’s systems:
The Chinese [hacking team] first went into a subcontractor, a global offshore payment processor that handled credit-card transactions, and then, having gained possession of that network, quietly entered the Company through a legitimate back door that had been installed on the Company’s network to administer consumer accounts. The initial breach was a work of art. The Chinese wrote a piece of customized software purely for that job. It was a one-of-a-kind ‘callback dropper,’ a Trojan horse that could be loaded with any of many malware modules, but otherwise stood empty, and regularly checked in with its masters to ask for instructions. Once inside the network, the Chinese were able to move laterally because the Company, for the sake of operational efficiency, had not compartmentalized its network. …
First, using ‘bounce points’ within the network to further obscure their presence, [the hackers] went after the central domain controller, where they acquired their own administrative account, effectively compromising 100 million user names and passwords and gaining the ability to push software packages throughout the network. Second, and more important, the Chinese headed into the network’s ‘build’ system, a part of the network where software changes are compiled and then uploaded to a content-distribution network for the downloading of updates to customers. In that position they acquired the ability to bundle their own software packages and insert them into the regular flow, potentially reaching 70 million personal computers or more. But, for the moment, they did none of that. Instead they installed three empty callback Trojans on three separate network computers and left them standing there to await future instructions. Opsec and his team concluded that the purpose was to lay the groundwork for the rapid construction of a giant botnet.
Opsec suspects the same payment processor vulnerability was exploited at other companies, as well, as part of a plan to launch this giant botnet as part of a global cyber-war. Considering he only caught the attack due to one small error made by the hackers, the discovery is unnerving. Opsec has his ideas on how to fight such a series of attacks, but he is holding off at the behest of his employer. Officially, at least. See the article for more information.

Hackers tend to the flock to the Internet’s underbelly, the Dark Web, and it remains inaccessible unless you have a Tor browser. According to the AIRS Association, hacker search engines are a lot easier to access than you think, read about it in “5 Hacker-Friendly Search Engines You Must Use.” The best-known hacker-friendly search engine is Shodan, which can search for Internet connected devices. While Shodan can search computers, smartphones, and tablets the results also include traffic lights, license plate readers, and anything with an Internet connection. The biggest problem, however, is that most of these devices do not have any security:
The main reason that Shodan is considered hacker-friendly is because of the amount and type of information it reveals (like banner information, connection types, etc.). While it is possible to find similar information on a search engine like Google, you would have to know the right search terms to use, and they aren’t all laid out for you.
Other than Shodan some of the other scary search engines are ZoomEye, I2P, PunkSPIDER, and Censys. These search engines range in the amount of data they share as well as their intended purpose, but they all reveal Internet connected devices. Beginners can use these search engines, but it takes a little more than technical know how to get results displayed. One needs to figure out how to use them before you even enter the first search result, because basic keyword will not get you far.
Hacker search engines are a good tool to use to find security breaches in your personal network or Web site. What will prevent most people from using them is the lack of experience, but with only a small amount of learning these search engines in the wrong hands are dangerous.

Do lawmakers understand how much they do not understand about technology? An article at Roll Call tells us, “Proposed Tech-Export Rules Bashed by Companies, Researchers.” It is perfectly understandable that human-rights organizations have pressed for limits on the spread of surveillance technology and “intrusion software”—a broad term for technology that steals data from computers and mobile devices, including some tools that can hijack hardware. Several Western governments have taken up that banner, imposing restrictions designed to keep this technology out of the hands of bad actors. In fact, 41 nations pledged their commitment to the cause when they signed on to the Wassenarr Arrangement in 2013.
While the intentions behind these restrictions are good, many critics insist that they have some serious unintended side effects for the good guys. Writer Gopal Ratnam reports:
Although such technologies can be used for malicious or offensive purposes, efforts to curb their exports suggests that the regulators didn’t understand the nature of the computer security business, critics say. Unlike embargoes and sanctions, which prohibit dealing with specific countries or individuals, the proposed restrictions would have forced even individual researchers working on computer security to obtain licenses, they say.
Besides, say some, the bad guys are perfectly capable of getting around the restrictions. Eva Galperin, of the nonprofit Electronic Frontier Foundation, insists human rights would be better served by applying pressure generally to repressive regimes, instead of trying to stay ahead of their hackers. Ratnam goes on to discuss specific ways restrictions get in the way of legitimate business, like hampering penetration tests or impeding communication between researchers. See the article for more details.

Apparently, money laundering has become a very complicated endeavor, with tools like Bitcoin “washers” available via the Dark Web. Other methods include trading money for gaming or other virtual currencies and “carding.” ZDNet discusses law enforcement’s efforts to keep up in, “How Machine Learning Can Stop Terrorists from Money Laundering.”
It will not surprise our readers to learn authorities are turning to machine learning to cope with new money laundering methods. Reporter Charlie Osborne cites the CEO of cybersecurity firm ThetaRay, Mark Gazit, when she writes:
By taking advantage of Big Data, machine learning systems can process and analyze vast streams of information in a fraction of the time it would take human operators. When you have millions of financial transactions taking place every day, ML provides a means for automated pattern detection and potentially a higher chance of discovering suspicious activity and blocking it quickly. Gazit believes that through 2017 and beyond, we will begin to rely more on information and analytics technologies which utilize machine learning to monitor transactions and report crime in real time, which is increasingly important if criminals are going to earn less from fraud, and terrorism groups may also feel the pinch as ML cracks down on money laundering.
Of course, criminals will not stop improving their money-laundering game, and authorities will continue to develop tools to thwart them. Just one facet of the cybersecurity arms race.

An article on Security Affairs called Boffins spotted over 100 snooping Tor HSDir nodes spying on Dark Web sites points to a new tactic that could be useful to companies offering Dark Web intelligence services. Within the inner workings of the Dark Web live at least 100, according to researchers, malicious hidden service directories (HSDirs). These are the relays of the network that allow people to visit hidden services. The author quotes researchers Filippo Valsorda and George Tankersley who presented at the Hack in the Box Security Conference,
When a person wants to host a hidden service, they have to advertise their service on a Tor Onion database, which is a DHT made up of a group of stable relay machines called HSDirs . The person who wants to visit the hidden service has to request information about that service from the database. Therefore, those relays or HSDirs can see who is making the request for a connection and when you want to connect. Therefore, to deanonymize a user’s traffic, an attacker could choose to become the HSDir nodes for the hidden service.
Additionally, researchers from Karlstad University in Sweden found 25 nodes within the The Onion Router (Tor) which showed entities snooping on the supposedly anonymous network. It appears gaps exist. The research shows an unspecified actor from Russia was eavesdropping. Are these snoopers Dark Web intelligence or cybercriminals? We shall stay tuned.

Vendors of stolen credit card information on the dark web are now verifying their customers’ identities, we learn from an article at the International Business Times, “The Fraud Industry: Expect to be KYC’d by Criminals When Buying Stolen Credit Cards on the Dark Web.” Yes, that is ironic. But these merchants are looking for something a little different from the above-board businesses that take KYC measures. They want to ensure potential clients are neither agents of law-enforcement nor someone who will just waste their time. Reporter Ian Allison cites Richard Harris, an expert in fraud detection through machine learning, when he writes:
Harris said some websites begin with a perfunctory request that the buyer produce some stolen card numbers of their own to show they are in the game. ‘There are various websites like that where undercover cops have been caught out and exposed. Like anybody else, they are in business and they take the security of their business seriously,’ he said.
Things have moved on from the public conception of a hacker in a hoodie who might hack the Pentagon’s website one day and steal some credit card details the next. That was 10 or 15 years ago. Today this is a business, pure and simple. It is about money and lots of it, like for instance the recent hit in Japan that saw a criminal gang make off with ¥1.4bn (£8.9m, $13m) from over 1,400 ATMs in under three hours. They simultaneously targeted teller machines located in Tokyo, Kanagawa, Aichi, Osaka, Fukuoka, Nagasaki, Hyogo,Chiba and Nigata. The Japanese police suspect more than 100 criminals were involved in the heist.
Harris is excited about the potential for machine learning to help thwart such sophisticated and successful, criminals. The article continues with more details about today’s data-thievery landscape, such as the dark-web bulletin boards where trade occurs, and the development of “sniffers” — fake wi-fi hubs that entice users with a promise of free connectivity, then snatch passwords and other delectable data. Allison also mentions the feedback pages on which customers review dark-web vendors, and delves into ways the dark web is being used to facilitate human trafficking. See the write-up for more information.

A new service has been launched in UK that enables users to find out if their confidential information is up for sale over the Dark Web.
As reported by Hacked in an article This Tool Lets You Scan the Dark Web for Your (Stolen) Personal Data, it says:
The service is called OwlDetect and is available for £3,5 a month. It allows users to scan the dark web in search for their own leaked information. This includes email addresses, credit card information and bank details.
The service uses a supposedly sophisticated algorithm that has alleged capabilities to penetrate up to 95% of content on the Dark Web. The inability of Open Web search engines to index and penetrate Dark Web has led to mushrooming of Dark Web search engines.
OwlDetect works very similar to early stage Google, as it becomes apparent here in the article:
This new service has a database of stolen data. This database was created over the past 10 years, presumably with the help of their software and team. A real deep web search engine does exist, however.
This means the search is not real time and is as good as searching your local hard drive. Most of the data might be outdated and companies that owned this data might have migrated to secure platforms. Moreover, the user might also have deleted the old data. Thus, the service just tells you that were you ever hacked or was your data was even stolen?

Recently a conference took place about cybersecurity in the enterprise world. In the Computer World article, Offensive hackers should be part of enterprise DNA, the keynote speaker’s address is quoted heavily. CEO of Endgame Nate Fick addressed the audience, which apparently included many offensive hackers, by speaking about his experience in the private sector and in the military. His perspective is shared,
“We need discontinuity in the adoption cure,” Fick said, “but you can’t hack back. Hacking back is stupid, for many reasons not just that it is illegal.” He argued that while it is illegal, laws change. “Remember it used to be illegal to drink a beer in this country, and it was legal for a kid to work in a coal mine,” he said. Beyond the issue of legality, hacking back is, what Fick described as, climbing up the escalatory ladder, which you can’t do successfully unless you have the right tools. The tools and the power or ability to use them legally has historically been granted to the government.
Perhaps looking toward a day where hacking back will not be illegal, Fick explains an alternative course of action. He advocates for stronger defense and clear government policies around cybersecurity that declare what constitutes as a cyberthreat offense. The strategy being that further action on behalf of the attacked would count as defense. We will be keeping our eyes on how long hacking back remains illegal in some jurisdictions.

Anti-surveillance hacker, Phineas Fisher, was covered in a recent Vice Motherboard article called, Hacker ‘Phineas Fisher’ Speaks on Camera for the First Time—Through a Puppet. He broke into Hacking Team, one of the companies Vice called cyber mercenaries. Hacking team and other firms sels hacking and surveillance tools to police and intelligence agencies worldwide. The article quotes Fisher saying,
I imagine I’m not all that different from Hacking Team employees, I got the same addiction to that electronic pulse and the beauty of the baud [a reference to the famous Hacker’s manifesto]. I just had way different experiences growing up. ACAB [All Cops Are Bastards] is written on the walls, I imagine if you come from a background where you see police as largely a force for good then writing hacking tools for them makes some sense, but then Citizen Lab provides clear evidence it’s being used mostly for comic-book villain level of evil. Things like spying on journalists, dissidents, political opposition etc, and they just kind of ignore that and keep on working. So yeah, I guess no morals, but most people in their situation would do the same. It’s easy to rationalize things when it makes lots of money and your social circle, supporting your family etc depends on it.
The topics of ethical and unethical hacking were discussed in this article; Fisher states the tools used by Hacking Team were largely used for targeting political dissidents and journalists. Another interesting point to note is that his evaluation of Hacking Team’s software is that it “works well enough for what it’s used for” but the real value it offers is “packaging it in some point-and-click way.” An intuitive user experience remains key.
