A new crime wave is hitting automated teller machines (ATMs); the common banking appliances are being rigged to spit out their entire cash supplies into a criminal’s waiting hands.

The crime is called “ATM jackpotting” and has targeted banking machines located in grocery shops, pharmacies and other locations in Taiwan, Europe, Latin America and, in the last several months, the United States. Rough estimates place the total amount of global losses at up to $60 million.

What is jackpotting?

ATM jackpotting is a combination of a physical crime and a cyberattack. Typically, a criminal with a fake ID enters a grocery shop or pharmacy posing as an ATM technician, then uses a crowbar to open the top of the ATM – the “top hat” – to gain access to the personal computer that operates the machine.

If a legitimate customer approaches the machine in the meantime, it can operate as usual until activated otherwise by the malware

Once he or she has access to the PC, they remove the hard drive, disable any anti-virus software, install a malware program, replace the hard drive and then reboot the computer. The whole operation takes about 30 seconds. The malware then enables the thief to remotely control the ATM and direct it to dispense all its cash on command.

An accomplice – the “mule” – later approaches the ATM to collect the bounty, as the “technician” remotely directs the machine to dispense all its cash. If a legitimate customer approaches the machine in the meantime, it can operate as usual until activated otherwise by the malware.

ATMs in supermarkets and pharmacies tend to be targeted because they may not be as well-protected, and store personnel likely would not know who is authorised to work on the ATM. In contrast, anyone approaching an ATM at a bank location would be more likely to be challenged.

Emergence of criminal activity

The crime first emerged in the United States several months ago, and the U.S. Secret Service, financial institutions and ATM manufacturers have been scrambling to find a solution. Older ATMs are particularly vulnerable.

In some cases, financial institutions have not embraced the highest levels of security offered by ATM manufacturers because of costs, and because previously the crime was not common in the U.S. One estimate is that losses north of $10 million have occurred in the U.S. just in the last couple of months.

There are solutions, and then there are ways to get around the solutions,” says Samir Agarwal, Accelerite’s general manager for security.

ATM protection technology

Accelerite is a California-based software company that focuses on the digital enterprise, including hybrid cloud infrastructure, endpoint security, Big Data analytics, and the Internet of Things. Accelerite’s solution to the ATM jackpotting problem is built on the company’s Sentient security framework.

Accelerite’s approach to ATM jackpotting is to immediately stop the dispensing of cash when any sign of trouble is detected. The system can track alarms, such as when a “top hat” is opened, when a hard disk is removed, if the antivirus software has been tampered with, and so on.

The system can send a notification within 20 seconds that the ATM is being hacked and then automatically shut down the machine. If the bad guy reboots the machine, the system can confirm there was a previous alert and shut it down over and over.

We create multiple lines of defense,” says Agarwal. “The criminal would decide it’s not worth his while and walk away.”

The consequences of jackpotting impact every level of the industry, including ATM manufacturers and financial institutions

Origins of ATM jackpotting

ATM jackpotting originated back in 2010 when Barnaby Jack, a New Zealand hacker and computer expert, demonstrated how he could exploit two ATMs and make them dispense cash on the stage at the Black Hat computer security conference in Las Vegas. Since then, malware has been created and made available on the “Dark Web” that can instruct an ATM to dispense all its cash on demand.

Previously ATM jackpotting attacks have focused on more cost-conscious global markets and those likely to use older-model ATMs with fewer security features. Strong U.S. law enforcement also likely prevented criminals from taking the risk – until now. Attacks in the United States have raised awareness.

There is more cognisance of the possibility of bad things happening,” says Agarwal. “This came out of nowhere and had not happened in the past in the United States. This crime is unlike what you hear about hacks or when data is stolen – there’s just money being stolen.”

Best practices to prevent an attack

However, the consequences impact every level of the industry, including ATM manufacturers and financial institutions. Also, the supermarket and grocery shops that are targeted face additional security challenges, and even consumers could lose confidence in ATMs if they think their personal information could be at risk.

There are best practices that can also prevent an attack. For example, an ATM computer could have a “white list” of approved applications and not allow anything to be installed that is not on the list; for instance, no malware. Another approach is to encrypt the disk drive so that a key or certificate is needed in order to install new software.

Agarwal notes that solving the challenge of ATM jackpotting illustrates the need to combine both physical and cybersecurity approaches to protect modern companies.

It’s the reality as we move into a more digital world,” he says. “Physical security at that level will be difficult to protect, and you will be depending more on cyber solutions. It’s the direction the world is moving into.

What characteristics do salespeople require in the physical security industry?
What characteristics do salespeople require in the physical security industry?

A basic tenet of sales is ABC – always be closing. But it's a principle that most professional salespeople would say oversimplifies the process. Especially in a sophisticated, high-tech market such as physical security, the required sales skills are much more involved and nuanced. We asked this week's Expert Panel Roundtable: What unique characteristics are required of salespeople in the arena of physical security systems?

Can microchip implants replace plastic cards in modern access control?
Can microchip implants replace plastic cards in modern access control?

A futuristic alternative to plastic cards for access control and other applications is being considered by some corporate users in Sweden and the United Kingdom. The idea involves using a microchip device implanted into a user’s hand. About the size of a grain of rice and provided by Swedish company Biohax, the tiny device employs passive near field communication (NFC) to interface with a user’s digital environment. Access control is just one application for the device, which can be deployed in lieu of a smart card in numerous uses. Biohax says more than 4,000 individuals have implanted the device. Using the device for corporate employees Every user is given plenty of information to make an informed decision whether they want to use the deviceCurrently Biohax is having dialogue with curious corporate customers about using the device for their employees. “It’s a dialogue, not Big Brother planning to chip every employee they have,” says Jowan Österlund, CEO at Biohax. Every user is given plenty of information to make an informed decision whether they want to use the device. Data capture form to appear here! “Proof of concept” demonstrations have been conducted at several companies, including Tui, a travel company in Sweden that uses the device for access management, ID management, printing, gym access and self-checkout in the cafeteria. Biohax is also having dialogue with some big companies in the United Kingdom, including legal and financial firms. Österlund aims to have a full working system in place in the next year or so. A Swedish rail company accepts the implanted chip in lieu of a paper train ticket. They accept existing implants but are not offering to implant the chips. Österlund says his company currently has no plans to enter the U.S. market. The device is large enough to locate easily and extract if needed, and small enough to be unobtrusive Access control credential The device is inserted/injected below the skin between the index finger and the thumb. The circuitry has a 10-year lifespan. The device is large enough to locate easily and extract if needed, and small enough to be unobtrusive. The only risk is the possibility of infection, which is true anytime the skin is pierced, and the risk is mitigated by employing health professionals to inject the chip. Use of the device as an access control credential or any other function is offered as a voluntary option; any requirement by an employer to inject the device would be illegal, says Österlund. It’s a convenient choice that is made “based on a well-informed decision by the customer.” Aversion to needles, for example, would make some users squeamish to implant the device. More education of users helps to allay any concerns: Some 10% of employees typically would agree quickly to the system, but a larger group of 50% to 60% are likely to agree over time as they get more comfortable with the idea and understand the convenience, says Österlund. Protection of information The passive device does not actively send out any signals as you walk. It is only powered up by a reader if a user has access rightsIn terms of privacy concerns, information contained on the device is in physical form and is protected. The passive device does not actively send out any signals as you walk. There is no battery. It is only powered up by a reader if a user has access rights. With use of the device being discussed in the United Kingdom, there has been some backlash. For example, Frances O’Grady, general secretary of the Trades Union Congress (TUC), has said: “Microchipping would give bosses even more power and control over their workers.” A big misconception is that the chip is a tracking device, says Österlund. It isn’t. “We love people to get informed,” says Österlund. “If they’re scared or apprehensive, they can just read up. It’s not used to control you – it’s used to give you control.”

Ethical consumption: should you buy security products ‘Made in China’?
Ethical consumption: should you buy security products ‘Made in China’?

Should ‘Made in China’ be seen as a negative in security systems and products? It’s an important and complex issue that merits a more detailed response than my recent comment in the Expert Panel Roundtable. For me, there are two sides of the answer to this question: Buying products that have certain negative attributes that are not in alignment with some part of a belief system or company mandate. Buying products that do not perform as advertised or do something that is unacceptable. For integrators and end users making the buying decisions, the drive to purchase products may not be based on either aspect and instead on the product that can do the best job for their business. But for others, a greater emphasis on the ethical implications of purchasing decisions drives decision-making. What is ethical consumption? Ethical consumption is a type of consumer activism that is based on the concept of ‘positive buying’ in that ethical products are favouredEthical consumption — often called ethical consumerism — is a type of consumer activism that is based on the concept of ‘positive buying’ in that ethical products are favoured, and products that are ethically questionable may be met with a ‘moral boycott’. This can be as simple as only buying organic produce or as complex as boycotting products made in a totalitarian regime that doesn't offer its citizens the same freedoms that we enjoy in the United States. Consider the goals of the Boston Tea Party or the National Consumers League (NCL), which was formed to protect and promote social and economic justice for consumers and workers in the United States and abroad. Some examples of considerations behind ethical consumption include fair trade, treatment of workers, genetic modification, locally made and processed goods, union-made products and services, humane animal treatment, and in general, labour issues and manufacturing practices that take these factors into account. Increase in ethical consumption The numbers show that ethical consumption is on the rise. In a 2017 study by Unilever, 33 percent of consumers reported choosing to buy and support brands that they believe are doing social or environmental good. In the same study, 53 percent of shoppers in the United Kingdom and 78 percent in the United States said they feel better when they buy products that are ‘sustainably’ produced. There’s clear evidence that products from some Chinese companies suffer from cybersecurity vulnerabilities Though the aforementioned question that sparked this conversation centres around concerns with products made in China, there are many other countries where, for example, governments/dictators are extremely repressive to all or parts of their populations, whose products, such as oil, diamonds, minerals, etc., we happily consume. There are also a number of countries that are a threat in terms of cybersecurity. It may be naive and simplistic to single out Chinese manufacturers. Impact on physical security products Product buying decisions based on factors other than product functionality, quality and price are also starting to permeate the security marketplace. While this hasn't been a large focus area from the business-to-business consumption side, it's something that should be considered for commercial security products for a variety of reasons. Hardware hacks are more difficult to pull off and potentially more devastating" There’s clear evidence that products from some Chinese companies suffer from cybersecurity vulnerabilities. Last fall, 30 U.S. companies, including Apple and Amazon, were potentially compromised when it was discovered that a tiny microchip in the motherboard of servers built in China that weren't a part of the original specification. According to a Bloomberg report, “This attack was something graver than the software-based incidents the world has grown accustomed to seeing. Hardware hacks are more difficult to pull off and potentially more devastating, promising the kind of long-term, stealth access that spy agencies are willing to invest millions of dollars and many years to get.” This, along with many other incidents, are changing the considerations behind purchasing decisions even in the physical security industry. Given that physical security products in general have been lax on cybersecurity, this is a welcome change. Combating tech-specific threats In early January, members of the U.S. Senate introduced bipartisan legislation to help combat tech-specific threats to national security posed by foreign actors and ensure U.S. technological supremacy by improving interagency coordination across the U.S. government. The bill creates the Office of Critical Technologies & Security at the White House, an indication that this issue is of critical importance to a number of players across the tech sector. Members of the U.S. Senate introduced bipartisan legislation to help combat tech-specific threats to national security posed by foreign actors To address a significant number of concerns around ethical production, there are certifications such as ISO 26000 which provides guidance on social responsibility by addressing accountability, transparency, ethical behaviour, respect for stakeholder interests, respect for rule of law, respect for international norms of behaviour and respect for human rights. While still emerging within physical security, companies that adhere to these and other standards do exist in the marketplace. Not buying products vulnerable to cyberattacks It may be counter-productive, even irresponsible, to brand all products from an entire country as unfit for purchasing. Some manufacturers’ products may be ethically questionable, or more vulnerable to cyberattacks than others; so not buying products made by those companies would make sense. The physical security industry might be playing a bit of catch up on this front, but I think we're beginning to see a shift toward this kind of responsible buying behaviour.
