More than one million online banking accounts were compromised in 2025 as cybercriminals increasingly relied on infostealers to collect financial credentials.
The cybersecurity firm Kaspersky says over one million online banking accounts served by the world’s 100 largest banks fell victim to infostealing malware, with credentials for those accounts being shared on the dark web.
“According to Kaspersky Digital Footprint Intelligence (DFI), in 2025 over one million online banking accounts served by the world’s 100 largest banks fell victim to infostealers: credentials for these accounts were being freely shared on the dark web. The countries with the highest median number of compromised accounts per bank were India, Spain, and Brazil.”
Kaspersky says attackers are increasingly shifting away from traditional computer-based banking malware and instead using credential theft techniques, including infostealer infections and the distribution of stolen data through underground marketplaces.
The company says mobile banking threats also increased, with attacks involving mobile banking malware rising by approximately 1.5 times in 2025 compared to the previous year. Kaspersky also reports that detections of infostealer malware on personal computers grew by 59% globally from 2024 to 2025, contributing to the rise in compromised credentials.
The findings are based on analysis conducted by Kaspersky Digital Footprint Intelligence, which tracks compromised credentials and data leaks associated with cybercriminal activity.
