Data In 'Mother Of All Breaches' Was Likely Stolen Years Ago
Bitdefender, Friday, June 20th, 2025
A massive database of stolen credentials resurfaces, but it comprises years of stolen data collated from previous breaches.
Widespread headlines warned of the 'mother of all breaches' this week, after cybersecurity news outlet Cybernews discovered a colossal trove of 1.2TB of exposed login credentials.
Despite the frenzy, experts stress that this isn't a data breach, but rather a repackaging of stolen data collected over many years.
Rather than being pulled from a recent hack, the data appears to be an aggregation of credentials harvested by infostealer malware and previous breaches. These credentials have been widely traded in cybercrime circles and are now simply resurfacing in a single database, briefly exposed online. That doesn't mean that it should be ignored, however.
