Data breaches have become increasingly prevalent, with notable incidents reported this year, including cases involving Coinbase, Grubhub, and DeepSeek. While these breaches are serious, recent findings by security researchers have revealed something far more alarming. According to a report from CyberNews, researchers discovered an astonishing collection of 30 exposed databases that contain between tens of millions and over 3.5 billion records each.
In total, these databases hold roughly 16 billion records, encompassing accounts from major platforms such as Google, Apple, and Telegram. Alarmingly, only one of the exposed sets had been previously reported, which contained 184 million records, a figure that “barely scratches the surface” compared to CyberNews’s findings. Given that there were over 5.56 billion internet users globally as of February 2025, it’s likely that many users have multiple accounts involved in this leak.
This reality makes it difficult to gauge the full extent of potentially compromised accounts. This situation is not merely a breach; it represents a serious threat for mass exploitation. With over 16 billion login records exposed, cybercriminals now possess remarkable access to personal credentials, which could facilitate account takeovers, identity theft, and targeted phishing attempts.
The majority of the exposed datasets are composed of information gathered from stealer malware, credential stuffing, and previously repackaged leaks, highlighting that this isn’t a single incident from one source. Moreover, many datasets are formatted clearly, displaying URLs, login details, and passwords—ideal data for modern ‘infostealers.’ The ownership of these leaked records remains uncertain, as they may belong either to security researchers or cybercriminals.
For affected users, immediate password changes are essential, along with employing two-factor authentication (2FA) wherever possible, or using innovative solutions like passkeys to enhance security.
