According to Kaspersky Lab, outdated software and mistakes in network configurations can make many ATMs vulnerable to hacking – even without the help of any malware.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 According to research conducted by Kaspersky Lab experts, this is because of the widespread use of outdated and insecure software, mistakes in network configuration and a lack of physical security for critical parts of the ATM.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.
Win a Poster Heater with Gadget and Takealot.com
This winter Gadget and Takealot.com are giving away three Poster Heaters, which look like posters but become heaters when you plug them in.
Three Gadget readers will each win a unit, valued at R550 each. To enter, follow @GadgetZA and @Takealot on Twitter and tell us on the @GadgetZA account how many Watts the heater consumes.
What’s the big deal about these heaters? Many of us are struggling to keep the balance between soaring electricity costs and the need to keep warm this winter.
However, the recently launched Poster Heater by EasyHeat and distributed in South Africa by Takealot.com is not only one of the most cost effective electric heaters currently on the market, it is also easy to setup and use.
As the name indicates, it is a poster similar to one you would hang on a wall. But, plug it in and it turns into a 300 Watt heater. The Poster Heater isn’t designed to heat hallways or large rooms, but rather smaller ones like a bedroom or a baby’s nursery or a dressing room.
It uses radiant heating, which means that it heats up in a couple of minutes and the heat is directed at the objects or people around it, quickly taking the chill out of the air and providing a comfortable ambient temperature.
The other advantage of radiant heating is that it doesn’t dry out the air like infrared or gas heaters. Users also don’t have to worry about their children or pets getting too close to it because, even though it gets hot, it can be touched.
To enter the competition follow the steps below:
Competition entry details:
3. The competition closes on 31 July 2018.
4. Winners will be notified via Twitter on 1 August and Takealot.com will be in touch to organise delivery.
5. The competition is only open to South African residents.
Deezer to host Hotstix’s Mandela tribute playlist
Deezer is celebrating Nelson Mandela on the centenary of his birthday by hosting a tribute playlist created by music legend Sipho “Hotstix” Mabuse.
Mabuse, a legendary figure in African music, first rose to prominence in the 1970s with his band Harari and later developed a name for himself as a solo artist. One of his best known songs was the global hit BurnOut in the 1980s.
The playlist takes the listener on a captivating musical journey through the life of Nelson Mandela. It was compiled by Mabuse, who consulted with Mandela’s family and friends to ensure that the music would be relevant and accurate. The playlist also features commentary by Mabuse, which was recorded in his Soweto home.
“I have tried to tell the story of the music that Madiba loved,” says Mabuse. “The Playlist excludes the time in prison obviously, as Madiba would not have had exposure to music in that time. We have focused on the music we know he loved before and after that period. This recording was really an emotional journey for me, but an incredible opportunity to document these memories.”
The playlist features the music the young Mandela loved, such as The Manhattan Brothers, Solomon Linda, Brenda Fassie and Miriam Makeba. It includes struggle songs from Chicco, Johnny Clegg, Hugh Masekela and Yvonne Chaka Chaka. The playlist also includes Mandela by Zahara, one of the younger artists who caught Madiba’s ear.
Mabuse also offers stories of his own songs, such as Shikisha, a song greatly beloved by the former President.
“I was delighted to share my thoughts and hope the listeners enjoyed the musical journey,” says Mabuse. “Madiba did enjoy music immensely and we all have a purpose wherever we are in the world to celebrate culture and to learn from different cultures and music forms and styles.”
This playlist was inspired by the Nelson Mandela 100 campaign, calling on corporates and individuals to act as sources of inspiration and engage in conversation and action.
