Millions of Credit and Debit Cards Stolen in Massive Data Breach

Millions of credit and debit cards have been leaked onto the dark web, according to cybersecurity firm Kaspersky. The firm says that malicious software, known as infostealer malware, is to blame.

The Scale of the Problem

Between 2023 and 2024, Kaspersky found that at least 2.3 million bank cards were compromised and their information shared online. This malware infected a staggering 26 million Windows devices during the same period. In fact, bank card information was stolen in roughly every 14th infection. Experts believe the actual number of infected devices is likely even higher, as stolen data often surfaces months or even years after the initial infection.

The Malware Culprits

Kaspersky identified Redline as the most common infostealer, accounting for 34% of infections in 2024. Another rapidly spreading malware, Risepro, is also a major concern. Risepro’s infections skyrocketed from 1.4% in 2023 to nearly 23% in 2024. This malware targets banking information and cryptocurrency wallets, often spreading through things like cracked software and game modifications.

Staying Safe

To protect yourself, Kaspersky recommends:

  • Monitoring bank statements regularly: Keep a close eye on your accounts for any unauthorized activity.
  • Enabling two-factor authentication: This adds an extra layer of security to your accounts.
  • Running regular security scans: Make sure your antivirus software is up-to-date and scan your devices frequently.

This massive data breach highlights the ongoing threat of infostealer malware and the importance of strong cybersecurity practices.
