Iagona ScrutisWeb Vulnerabilities Could Expose ATMs to Remote Hacking

/in


Several vulnerabilities discovered in the ScrutisWeb ATM fleet monitoring software made by French company Iagona could be exploited to remotely hack ATMs. 

The security holes were discovered by Synack Red Team members and they were patched by the vendor in July 2023 with the release of ScrutisWeb version 2.1.38. 

ScrutisWeb allows organizations to monitor banking or retail ATM fleets from a web browser, enabling them to quickly respond to problems. The solution can be used to monitor hardware, reboot or shut down a terminal, send and receive files, and modify data remotely. It’s worth noting that ATM fleets can include check deposit machines and payment terminals in a restaurant chain. 

The Synack researchers identified four types of vulnerabilities that have been assigned the CVE identifiers CVE-2023-33871, CVE-2023-38257, CVE-2023-35763 and CVE-2023-35189. 

The flaws include path traversal, authorization bypass, hardcoded cryptographic key, and arbitrary file upload issues that can be exploited by remote, unauthenticated attackers.

Threat actors could exploit the flaws to obtain data from the server (configurations, logs and databases), execute arbitrary commands, and obtain encrypted administrator passwords and decrypt them using a hardcoded key. 

The researchers said an attacker can leverage the flaws to log into the ScrutisWeb management console as an admin and monitor the activities of connected ATMs, enable management mode on the devices, upload files, and reboot or power them off.

Hackers could also exploit the remote command execution vulnerability to hide their tracks by deleting relevant files.

“Additional exploitation from this foothold in the client’s infrastructure could occur, making this an internet-facing pivot point for a malicious actor,” explained Neil Graves, one of the researchers involved in this project.

“Further examination would be required to determine if custom software could be uploaded to individual ATMs to perform bank card exfiltration, Swift transfer redirection, or other malicious activities. However, such additional testing was out of scope of the assessment,” Graves said.

Widely Used Bitcoin ATMs Have Major Security Flaws, Researchers Warn

Many of the Bitcoin ATMs that have popped up everywhere from gas stations and smoke shops to bars and malls across the U.S. have major security vulnerabilities that render them susceptible to hackers, according to a new report by security researchers with crypto exchange Kraken.

The website howmanybitcoinatms.com estimates there are over 42,000 active Bitcoin ATMs across the U.S., a massive surge from January 2021, when Reuters reported the site listed 28,000. Such ATMs allow users to buy cryptocurrency with cash or credit (though not always the reverse) and process sensitive financial data. Unlike when dealing with regular ATMs operated by banks, the distributed nature of cryptocurrency networks and a lack of regulations mean customers are likely to have less recourse if something goes disastrously wrong. Moreover, target markets for the devices include people who keep money in cryptocurrency rather than banks and people who don’t want their transfers to attract attention, whether for legitimate purposes or otherwise. Many are also located in dicey locations like liquor stores. Thus Bitcoin ATMs have been juicy targets for malware and scams in the past.

Kraken discovered a number of software and hardware flaws with the General Bytes BATMtwo (GBBATM2) model of ATMs. Coin ATM Radar estimates the manufacturer has provided nearly 23% of all crypto ATMs worldwide; in the U.S., that percentage is 18.5%, while in Europe, it is 65.4%.

For example, owners have installed many GBBATM2 units without changing the default admin QR code that serves as a password, meaning that anyone who obtains that code could possibly take control of it. Other issues Kraken wrote it found included a lack of secure boot mechanisms, meaning a hacker could trick a GBBATM2 into running malicious code, and “critical vulnerabilities in the ATM management system.”

The QR code issue is particularly serious, Kraken’s researchers wrote, because it found that the default code is shared across units. This is a bit like buying a new computer and forgetting to change the password to something…

Crooks have acquired proprietary Diebold software to “jackpot” ATMs

Diebold Nixdorf, which had sales of $ 3.3 billion from ATM sales and service last year, is warning stores, banks, and other customers of a new hardware-based form of “jackpotting,” the industry term for attacks that thieves use to quickly empty ATMs.

The new variation uses a device that runs parts of the company’s proprietary software stack. Attackers then connect the device to the ATM internals and issue commands. Successful attacks can result in a stream of cash, sometimes dispensed as fast as 40 bills every 23 seconds. The devices are attached either by gaining access to a key that unlocks the ATM chassis or by drilling holes or otherwise breaking the physical locks to gain access to the machine internals.

In previous jackpotting attacks, the attached devices, known in the industry as black boxes, usually invoked programming interfaces contained in the ATM operating system to funnel commands that ultimately reached the hardware component that dispenses cash. More recently, Diebold Nixdorf has observed a spate of black box attacks that incorporated parts of the company’s proprietary software.
