The Addka72424 3.3B email compilation is not a single-company breach, but a large aggregation of email addresses from prior breaches and combolists. leaksear.ch indexes 61.3M email records from the corpus, creating a useful exposure check for phishing and credential-stuffing risk.
A Facebook-targeted credential-stuffing combo list contains 1.3 million email, username, and plaintext password pairs. The dataset is described as aggregated from prior public breaches and infostealer logs, not a new breach of Facebook itself.
