Cybercrime-as-a-Service: Where Do We Go from Here?

big dataToday the cybercrime economy is estimated to be worth anything from $600bn to over $1.5 trillion. “Estimated” is the key word here, because in many ways it’s impossible to know for certain just how much money is made off the back of fraud, data theft, ransomware, crypto-mining etc. But what we do know is that the “as-a-service” model is a key component, enabling unskilled criminals to cash in on the cyber-craze and get rich relatively quickly off the back of poor corporate security and fallible consumers.

For a recent feature I interviewed some experts to better understand the scale of the problem, and what hope there is of some kind of comeback for good guys.

The web of profit

One of the best recent reports into the cybercrime economy was the Bromium-sponsored Into the Web of Profit analysis by University of Surrey senior lecturer, Michael McGuire. He explained that the popularity of the cybercrime-as-a-service (CaaS) model boils down to the sheer range of opportunities it affords the criminal fraternity.

“If you accept cybercrime as a hi-tech crime then you need hi-tech tools and methods to facilitate it, and the CaaS model is opening this market up. There are many extremely well organised criminal groups that are developing these tools, and the everyday man on the street is able to make use of their work as a result,” he told me.

“Given the wide range of perpetrators that are looking to make use of some form of CaaS, there really aren’t many types of cybercrime activity where it doesn’t play a role. Everyone can now get hold of various types of attack and varying levels of sophistication. Of course, it isn’t just malware – we are seeing all sorts of CaaS that is helping money laundering and breaking into banks.”

SANS-certified instructor Matthew Toussain explained that CaaS has rapidly matured over the past 10 years.

“The service offerings originally began over a decade ago as Distributed Denial of Service-for-hire before growing into exploit kit rentals and now ransomware as a service. Now the model and process for attackers has settled into a highly mature state where iteration of process and method is no longer necessary for intrusion sets to maintain these services,” he told me.

“Often the differentiator today is which malicious ‘provider’ offers more features or lower prices. These systems are generally driven by a modern web interface. While transactions are generally handled in Bitcoin it is not uncommon to see PayPal used as a method of payment.

Hope for the future?

For those who believe that cybercrime is a relatively harmless form of criminal activity in the grand scheme of things, McGuire had some home truths. His report explained that cyber-criminals often re-invest their profits, not just into online activities but narcotics, human trafficking and more.

“Anything that furthers criminal activity, whether it is CaaS or more guns on the streets is bad for society, and CaaS is certainly doing just that,” he added. “CaaS is also growing the potential opportunity for crime – even people that don’t have a criminal background can now contribute towards cybercrime. It is raising the criminal threat to a level where organisations, and even nation states that can make use of these tools.”

So is there any hope of a fightback by governments, organisations and law enforcers? Not according to Toussain.

“Law enforcement is by its very nature reactive, and for many organisations this may already be too late. Moreover, law enforcement has failed to effectively combat existing threats and continues to allow these black-market services to grow into a burgeoning industry,” he said. “There are a host of difficulties including international and extradition restrictions imposed upon the law enforcement community that make it unlikely we will see a marked improvement in the short-term.”

In fact, many experts suggested that a bigger impact on the problem could be made if organisations just got better at cybersecurity, making themselves a harder target.

“Law enforcement tries to disrupt trust in the black markets. These are anonymous activities, so if people don’t trust the seller, the market goes away. But the are many, many markets,” said James Lewis, director of the technology and public policy program at thinktank the Center for Strategic and International Studies. “Better security is always good, and this includes basic hygiene and thinking about encryption and backup to manage ransomware risk.”

Bromium CEO, Gergory Webb unsurprisingly believes that security technology can play a part here, providing innovative solutions to help keep corporates safe.

“The platform criminality model is productising malware and making cybercrime as easy as shopping online. Not only is it easy to access cyber-criminal tools, services and expertise: it means enterprises and governments alike are going to see more sophisticated, costly and disruptive attacks as The Web of Profit continues to gain momentum,” he explained. “We can’t solve this problem using old thinking or outmoded technology. By focusing on new methods of cybersecurity that protect rather than detect, we believe we can make cybercrime a lot harder.”

However, responsibility lies not just with law enforcement, CISOs or the security industry, but also the online platforms like Facebook that are abused by cyber-criminals to steal personal data, spread malware, trade attack tools and techniques, launder money and more.

“In terms of industry, the reactive security posture that many firms adopt is not enough and must improve if we are to disrupt hackers’ revenue channels, whether that is software enabled or developing better security skills for staff members,” concluded McGuire.

“But the missing element of responsibility is what legitimate platforms themselves can do. They have to get organised with regards to cybercrime and step up to the plate with better measures and much more transparent data practices.”

Japan’s Cybercrime Underground: a Ticking Time Bomb?

japanese toriChina, Russia, Eastern Europe, the Middle East – the list of hacking hotspots on the radar of most threat intelligence operatives is growing all the time. But what about Japan? For such an apparently technologically advanced nation, you might be surprised to learn its cybercrime underground is still in its infancy.

That’s the key takeaway from a new Trend Micro report I covered for Infosecurity and IDG Connect recently.

The security giant claimed that Japanese cybercriminals haven’t yet built up the technical know-how to create malware themselves, preferring to buy from other countries and then share tips on how to use it on many of the local underground bulletin board forums.

These forums also sell the usual suspects of child porn, stolen card data, stolen phone numbers, weapons, and so on.

There were several interesting distinctions Trend Micro uncovered between the Japanese cybercrime underground and elsewhere:

  • Cybercriminals accept gift cards from Amazon and the like in lieu of payment
  • CAPTCHA in Japanese is used to access the forums, keeping their membership mainly to locals
  • URLs for some secret BBSs hosted on Tor and other anonymising platforms can actually be found published in books and magazines
  • Japanese cybercriminals are ultra cautious, even using code words when discussing certain contraband, like the kanji character for “cold” when referring to methamphetamine.

So far, the notorious yakuza organised crime gangs have largely stayed out of the game, and that’s the way it’ll stay for some time to come, report author Akira Urano told me. That’s because of a combination of strict cybersecurity laws and the fact that offline scams still work a treat. But it might not be that way forever.

“If ever organized crime groups like the yakuza ever venture into darknets, all they would need is the aid of tech-savvy individuals to engage in criminal transactions,” Urano argues in the report.

I was curious to hear a second opinion on Japanese cybercrime, so I asked FireEye’s local experts.

They hit me with a few stats from the National Police Agency (NPA) which show that, infancy or not, there’s a pretty healthy cybercrime industry in Japan.

Some 88 people were arrested for cybercrimes in the first half of the year, 58% of whom were Japanese. The country is also a major victim of banking fraud – second only to the US, according to other stats.

The country’s public and private sectors also have to withstand a barrage of likely state-backed cyber attacks, launched from outside the country.

Japan’s strengths in advanced technology and engineering, as well as its hand in territorial disputes, have made it a target for China.

Aerospace and defence, transportation, high-tech, construction and telecoms are some of the highest risk industries.

FireEye told me the following by email.

“FireEye observes similar tactics and techniques on Japanese networks as we see elsewhere in the world. However, the key difference is localization: APT actors tailor their phishing e-mails, CnC infrastructure, and even their exploits to Japanese end users. For instance, we have observed threat activity against Japanese targets exploit the Japanese Ichitaro word processing system; zero days against the program are not uncommon.”


Cameron on a hiding to nothing if he really does want encrypted comms ban

whatsapp logoThis week, prime minister David Cameron seemed to indicate that if he is elected this May he’ll do all he can to ensure strongly encrypted communications are banned in the UK.

Well, that’s the gist of what he said. More correctly, he made it clear that no form of comms should exist where, in extremis, the security services can’t eavesdrop on private conversations – to stop criminals, terrorists etc.

His comments have been widely criticised in the media and by the technology industry, and rightly so.

Although others including the FBI, US attorney general Eric Holder and even Europol have voiced concerns about encrypted communications, none have gone as far as Cameron – who is now apparently off to the US to try and get support for his plans from Barack Obama.

A few thoughts sprung to mind as I reported on this breaking story:

  • If Cameron thinks he can take on the might of Apple, Google et al over this, he’s mistaken.
  •  His comments are at odds with European security agency Enisa which has just released a document praising encryption and calling for MORE privacy enhancing technologies (PETs), not fewer
  • There’s no evidence that the Paris attacks would have been prevented if encrypted comms were banned
  • The UK’s burgeoning tech industry will suffer
  • UK business will react angrily if they can’t use strongly encrypted comms, as will UK entrepreneurs –  it’s sending out a dreadful signal to potential investors in our supposedly liberal democratic country. Also, these are exactly the sort of traditional Tory supporters Cameron needs on side.
  • If encrypted comms were banned, or backdoors were engineered into products so the security services could access them if needed, the bad guys would eventually find a way of exploiting them too.
  • Terrorists and criminals will continue to use encrypted comms, downloaded from regions where they are still legal.

Sophos global head of security research James Lyne summed up the whole farce neatly in comments he sent me by email:

“Even if regulation was brought in to force legitimate companies to use encryption the government (in extremis) could intercept, unless they plan to build a great firewall of China (but even bigger and better – or sinister) to prevent people getting their hands on open source tools available in other countries it isn’t going to stop the darker side of the net from using it,” he told me.

“At the end of the day, terrorists will use any tools at their disposal to communicate, so this is unlikely to solve the real problem. The intention behind the statement was likely a little different to the way in which it has appeared but the suggestion as it stands would do the UK more harm than good and clearly lacks insight into how the internet works or how such controls might be implemented.”
