Your ATM is hacked

Published

on

According to Kaspersky Lab, outdated software and mistakes in network configurations can make many ATMs vulnerable to hacking – even without the help of any malware.

Almost any ATM in the world could be illegally accessed and jackpotted with or without the help of malware. According to research conducted by Kaspersky Lab experts, this is because of the widespread use of outdated and insecure software, mistakes in network configuration and a lack of physical security for critical parts of the ATM.

For many years the biggest threat to the customers and owners of ATMs were skimmers – special devices attached to an ATM in order to steal data from bank card magstripes. But as malicious techniques have evolved, ATMs have been exposed to more danger. In 2014, Kaspersky Lab researchers discovered Tyupkin – one of the first widely known examples of malware for ATMs, and in 2015 company experts uncovered the Carbanak gang, which, among other things was capable of jackpotting ATMs through compromised banking infrastructure. Both examples of attack were possible due to the exploitation of several common weaknesses in ATM technology, and in the infrastructure that supports them. This is only the tip of the iceberg.

In an effort to map all ATM security issues, Kaspersky Lab penetration testing specialists have conducted research based on the investigation of real attacks, and on the results of ATM security assessments for several international banks.

As a result of the research, the experts have demonstrated that malware attacks against ATMs are possible due to several security issues. First is that all ATMs are PCs running on very old versions of operation systems such as Windows XP. This makes them vulnerable to infection with PC malware and attack via exploits. In the vast majority of cases, the special software that allows the ATM’s PC to interact with banking infrastructure and hardware units, processing cash and credit cards, is based on XFS standard. This a rather old and insecure technology specification, originally created in order to standardise ATM software, so that it can work on any equipment regardless of manufacturer. Should malware successfully infect an ATM, it receives almost unlimited capabilities in terms of control over that ATM: it can turn the PIN pad and card reader into a “native” skimmer or just give away all the money stored in the ATM, upon a command from its hacker.

In many cases observed by Kaspersky Lab researchers, criminals don’t have to use malware to infect the ATM or the network of the bank it’s attached to. That is possible because of the lack of physical security for the ATMs themselves – a very common issue for these devices. Very often ATMs are constructed and installed in a way that means a third-party can easily gain access to the PC inside the ATM, or to the network cable connecting the machine to the Internet.

By gaining even partial physical access to the ATM, criminals potentially can:

  • Install specially programmed microcomputer (a so called black box) inside the ATM, which will give attackers remote access to the ATM;
  • Reconnect the ATM to a rogue processing center.

A fake processing center is software that processes payment data and is identical to the bank’s software despite the fact that it doesn’t belong to the bank. Once the ATM is reconnected to a fake processing center, attackers can issue any command they want. And the ATM will obey.

The connection between ATMs and the processing center can be protected in various ways. For example, using a hardware or software VPN, SSL/TLS encryption, a firewall or MAC-authentication, implemented in xDC protocols. However, these measures are not often implemented. When they are, they are often misconfigured and even vulnerable, something that might only be discovered during an ATM security assessment. As a result, criminals don’t have to manipulate the hardware, they just exploit insecurities in the network communication between the ATM and the banking infrastructure.

How to stop ATM jackpotting:

“The results of our research show that even though vendors are now trying to develop ATMs with strong security features, many banks are still using old insecure models and this makes them unprepared for criminals actively challenging the security of these devices. This is today’s reality that causes banks and their customers huge financial losses. From our perspective this is the result of a longtime misbelief, that cybercriminals are only interested in cyberattacks against Internet banking. They are interested in these attacks, but also increasingly see the value in exploiting ATM vulnerabilities, because direct attacks against such devices significantly shortens their route to real money,” said Olga Kochetova, security expert at Kaspersky Lab’s Penetration Testing department.

Although the security issues listed above most probably affect a lot of ATMs around the world, it doesn’t mean that the situation cannot be fixed. ATM manufacturers can reduce the risk of attack on cash machines by applying the following measures:

  • Firstly, it is necessary to revise the XFS standard with an emphasis on safety, and introduce two-factor authentication between devices and legitimate software. This will help reduce the likelihood of unauthorised money withdrawals using trojans and attackers gaining direct control over ATM units.
  • Secondly, it is necessary to implement “authenticated dispensing” to exclude the possibility of attacks via fake processing centers.
  • Thirdly, it is necessary to implement cryptographic protection and integrity control over the data transmitted between all hardware units and the PCs inside ATMs.

Bring your network with you

At last week’s Critical Communications World, Motorola unveiled the LXN 500 LTE Ultra Portable Network Infrastructure. It allows rescue personal to set up dedicated LTE networks for communication in an emergency, writes SEAN BACHER.

In the event of an emergency, communications are absolutely critical, but the availability of public phone networks are limited due to weather conditions or congestion.

Motorola realised that this caused a problem when trying to get rescue personnel to those in need and so developed its LXN 500 LTE Ultra Portable Network Infrastructure. The product is the smallest and lightest full powered broadband network to date and allows the first person on the scene to set up an LTE network in a matter of minutes, allowing other rescue team members to communicate with each other.

“The LXN 500 weighs six kilograms and comes in a backpack with two batteries. It offers a range of 1km and allows up to 100 connections at the same time. However, in many situations the disaster area may span more than 1km which is why they can be connected to each other in a mesh formation,” says Tunde Williams, Head of Field and Solutions Marketing EMEA, Motorola Solutions.

The LXN 500 solution offers communication through two-way radios, and includes mapping, messaging, push-to-talk, video and imaging features onboard, thus eliminating the need for any additional hardware.

Data collected on the device can then be sent through to a central control room where an operator can deploy additional rescue personnel where needed. Once video is streamed into the control room, realtime analytics and augmented reality can be applied to it to help predict where future problem points may arise. Video images and other multimedia can also be made available for rescuers on the ground.

“Although the LXN 500 was designed for the seamless communications between on ground rescue teams and their respective control rooms, it has made its way into the police force and in places where there is little or no cellular signal such as oil rigs,” says Williams.

He gave a hostage scenario: “In the event of a hostage situation, it is important for the police to relay information in realtime to ensure no one is hurt. However the perpetrators often use their mobile phones to try and foil any rescue attempts. Should the police have the correct partnerships in place they are able to disable cellular towers in the vicinity, preventing any in or outgoing calls on a public network and allowing the police get their job done quickly and more effectively.”

By disabling any public networks in the area, police are also able to eliminate any cellular detonated bombs from going off but still stay in touch with each other he says.

The LXN 500 offers a wide range of mission critical cases and is sure to transform communications and improve safety for first responders and the people they are trying to protect.

Kaspersky moves to Switzerland

As part of its Global Transparency Initiative, Kaspersky Lab is adapting its infrastructure to move a number of core processes from Russia to Switzerland.

Published

on

This includes customer data storage and processing for most regions, as well as software assembly, including threat detection updates. To ensure full transparency and integrity, Kaspersky Lab is arranging for this activity to be supervised by an independent third party, also based in Switzerland.

Global transparency and collaboration for an ultra-connected world

The Global Transparency Initiative, announced in October 2017, reflects Kaspersky Lab’s ongoing commitment to assuring the integrity and trustworthiness of its products. The new measures are the next steps in the development of the initiative, but they also reflect the company’s commitment to working with others to address the growing challenges of industry fragmentation and a breakdown of trust. Trust is essential in cybersecurity, and Kaspersky Lab understands that trust is not a given; it must be repeatedly earned through transparency and accountability.

The new measures comprise the move of data storage and processing for a number of regions, the relocation of software assembly and the opening of the first Transparency Center.

Relocation of customer data storage and processing

By the end of 2019, Kaspersky Lab will have established a data center in Zurich and in this facility, will store and process all information for users in Europe, North America, Singapore, Australia, Japan and South Korea, with more countries to follow. This information is shared voluntarily by users with the Kaspersky Security Network (KSN) an advanced, cloud-based system that automatically processes cyberthreat-related data.

Relocation of software assembly

Kaspersky Lab will relocate to Zurich its ‘software build conveyer’ — a set of programming tools used to assemble ready to use software out of source code. Before the end of 2018, Kaspersky Lab products and threat detection rule databases (AV databases) will start to be assembled and signed with a digital signature in Switzerland, before being distributed to the endpoints of customers worldwide. The relocation will ensure that all newly assembled software can be verified by an independent organisation and show that software builds and updates received by customers match the source code provided for audit.

Establishment of the first Transparency Center

The source code of Kaspersky Lab products and software updates will be available for review by responsible stakeholders in a dedicated Transparency Center that will also be hosted in Switzerland and is expected to open this year. This approach will further show that generation after generation of Kaspersky Lab products were built and used for one purpose only: protecting the company’s customers from cyberthreats.

Independent supervision and review

Kaspersky Lab is arranging for the data storage and processing, software assembly, and source code to be independently supervised by a third party qualified to conduct technical software reviews. Since transparency and trust are becoming universal requirements across the cybersecurity industry, Kaspersky Lab supports the creation of a new, non-profit organisation to take on this responsibility, not just for the company, but for other partners and members who wish to join.
