- On average, every 14th infostealer infection results in stolen credit card information

Islamabad: Kaspersky Digital Footprint Intelligence estimates that 2.3 million bank cards were leaked on the dark web, based on an analysis of data-stealing malware log files from 2023-2024. On average, every 14th infostealer infection results in stolen credit card information, with nearly 26 million devices compromised by infostealers, including more than 9 million in 2024 alone.
Infostealer malware is not only designed to extract financial information, but also credentials, cookies and other valuable user data, which is compiled into log files and then distributed within the dark web underground community. An infostealer can infect a device if a victim unknowingly downloads and runs a malicious file, for example one disguised as legitimate software.. It can be spread through phishing links, compromised websites, malicious attachments in emails or messengers and various other methods. It targets both personal and corporate devices.
“The actual number of infected devices is even higher. Cybercriminals often leak stolen data in the form of log files months or even years after the initial infection, and compromised credentials and other information continue to surface on the dark web over time. Therefore, the more time passes, the more infections from previous years we observe. We forecast the total number of devices infected with infostealer malware in 2024 to be between 20 million and 25 million, while for 2023, the estimate ranges between 18 million and 22 million,” says Sergey Shcherbel, expert at Kaspersky Digital Footprint Intelligence.
In 2024, Redline remained the most widespread infostealer, accounting for 34% of the total number of infections. The most significant surge in 2024 was in infections caused by Risepro, whose share of total infections increased from 1.4% in 2023 to almost 23% in 2024. “RisePro is a growing threat. It was first discovered two years ago, but seems to be gaining momentum. The stealer primarily targets banking card details, passwords and cryptocurrency wallet data, and may be spreading under the guise of key generators, cracks for various software and game mods,” explains Sergey Shcherbel. Another rapidly growing stealer is Stealc, which first appeared in 2023 and increased its share from nearly 3% to 13%.
