Woburn, MA – October 6, 2022 — In the early days of the COVID-19 pandemic, the number of attacks on ATMs and PoS terminals significantly decreased due to the limited amount of in person transactions. Now that old spending patterns are back, threat actors’ are leveraging point of sale and ATM attacks again. HydraPoS and AbaddonPoS are the most widespread malware families in 2022, accounting for roughly 71% of all detections. For ATMs the most active malware is Ploutus, accounting for 3% of all detections in the first eight months of 2022.
Cybercriminals attack embedded systems used in ATMs and point-of-sale (PoS) terminals to steal cash, credit card credentials and personal data, and penetrate systems to gain control over all devices within a network. In doing so, attackers can obtain thousands of dollars overnight. Many Windows versions used in ATMs reached the end of their support long ago and may be an easy target, while PoS terminals are used by many businesses with a low cybersecurity maturity level.
A look at the numbers: attackers’ activity returning to pre-pandemic levels
When the pandemic hit, the number of attacks decreased sharply compared to the previous year from roughly 8000 in 2019 to 5000 in 2020. According to the experts’ assessment, this occurred for several reasons including a reduction in the total number of ATMs across the world, their shutdown during pandemic restrictions, and an overall decrease in spending. As a consequence, attackers saw their market contract in terms of the number of their targets.
Today with the world less restricted, old spending patterns are back and threat actors’ activity is picking up the pace. In 2021, the number of devices encountered with ATM/PoS malware was up by 39% compared to the previous year. In the first eight months of 2022, the number grew by 19% compared to the same period of 2020, and by nearly 4% compared to 2021. In total, 4173 devices were attacked in January-August of 2022.
Given this trend, experts expect the number of attacks on ATM/PoS devices to increase further in the fourth quarter of 2022.
PoS malware is the most widespread
HydraPoS and AbaddonPoS account for roughly 71% of all ATM/PoS malware detections in 2020-2022, with 36% and 35%, respectively. The leader of the rating, HydraPoS, originates from Brazil and is known for cloning credit cards. According to Kaspersky Threat Intelligence Portal reports, this family was used in attacks involving social engineering.
“There are different techniques that depend on who is conducting the attack and which family is used,” said Fabio Assolini, head of research center for Kaspersky Latin America. “Attackers make phone calls or even come to victims’ offices. They impersonate an employee of a bank or credit card company and try to convince the victim to install malware as if it were a system update.”

The most active ATM/PoS malware families in 2022 by share of detections
The TOP-5 also includes Ploutus (3%), the malware family used for modifying legitimate software and privilege escalation to control ATMs and obtain administrative privileges that allow criminals to jackpot ATMs on demand. RawPoS (the malware able to extract the full magnetic stripe data from volatile memory) and Prilex (the malware abusing processes related to PoS software and credit and debit card transactions), account for 2% per each. The other 61 analyzed families and modifications account for less than 2% per each.
"PoS malware is more widespread than ATM malware because it gives fairly easy access to money,” Fabio adds. “If ATMs are usually protected well enough, the owners of cafes, restaurants, and shops often don’t even think about the cybersecurity of their payment terminals. This makes them a target for attackers. Moreover, new criminal business models like malware-as-a-service emerge to lower the skills bar for would-be threat actors,"
