Data study

The most frequently targeted companies

Ranked by how often a company is named in a tracked data-exposure incident — not by confirmed breaches. Most entries in this tracker are unverified listings posted by ransomware and extortion groups, which count for less here and are shown separately. Appearing high on this list is not a finding that a company was breached.

0 of the 25 companies below have no corroborated incident at all — every entry against their name is an extortion group’s own posting, which the company has not confirmed and which no regulator, breach index or named news outlet has independently reported. Read the ranking as a measure of who is being named, not of who has been breached.

Ordered by incident count weighted by evidence, so a corroborated breach counts more than an unverified listing — the same weighting the DoxxScan™ Rating uses. Only incidents where a source described a loss of personal information are counted; outages, destructive attacks and vulnerability advisories are tracked but are not breaches. Updated as new incidents are recorded.
