Inbox flooded with sign-up messages? Email bombing explained
AI Summary
ESET's WeLiveSecurity explains email bombing — a technique where victims are flooded with sign-up confirmation emails to mask fraudulent activity, such as unauthorized financial transactions or account takeovers occurring simultaneously. The tactic exploits the signal-to-noise problem in overloaded inboxes and is often a precursor indicator of a more serious breach. Security teams and end users should treat sudden high-volume sign-up email floods as a potential incident trigger requiring immediate account review.
