Pitney Bowes data breach: 8.2M accounts exposed
Severity: medium · Patch status: no-fix-needed · Since 2026-04-27
In April 2026, the hacking collective ShinyHunters claimed to have obtained data from Pitney Bowes as part of a broader extortion campaign that also named several other organisations. After negotiations allegedly failed, the group publicly released the data which included 8.2M unique email addresses, along with names, phone numbers and physical addresses. A subset of the data also included Pitney Bowes employee records with job titles. Exposed data: email addresses, job titles, names, phone numbers, physical addresses. The breach dates from Apr 20, 2026; Have I Been Pwned loaded it on Apr 27, 2026.
What to do
- If you had a Pitney Bowes account, change its password and the password of any other account that reused it.
- Turn on multi-factor authentication wherever it is offered.
- Check whether your addresses are in this breach at https://haveibeenpwned.com.
- Expect targeted phishing that quotes the leaked details; verify any unexpected contact out of band.
