If you've ever had an account or relationship with MOVEit, it's worth checking whether your personal data was exposed in this incident. Here's what happened, what data was involved, and what to do about it.
What Happened
In May-June 2023, the Cl0p ransomware group exploited a previously unknown (zero-day) vulnerability in Progress Software's MOVEit Transfer file transfer tool, used by thousands of organizations — including government agencies, universities, and large corporations — to move sensitive files. Because MOVEit is a shared piece of software used by so many organizations, this became one of the largest supply-chain breaches ever, affecting over 2,000 organizations and tens of millions of individuals globally.
What Data Was Exposed
The specific data exposed varies by which organization used MOVEit to transfer your information — it could include names, Social Security numbers, financial account details, health information, or other personal data, depending on what that particular organization was transferring at the time.
Why This Still Matters
Exposed data doesn't expire. It's sold, traded, and reused for years, fueling credential stuffing attacks — automated attempts to reuse your email and password combination across other sites. If you reused a password anywhere, one old exposure can compromise several current accounts.

Frequently Asked Questions
When did the MOVEit data breach happen?
The Cl0p ransomware group began exploiting the MOVEit Transfer zero-day vulnerability around 27 May 2023. Progress Software disclosed and patched the vulnerability shortly after, but the group had already exfiltrated data from thousands of organizations by then.
What data was stolen in the MOVEit breach?
The specific data varies by organization, since MOVEit is a file-transfer tool used by many different companies and agencies for different purposes. Exposed data across affected organizations included names, Social Security numbers, financial details, health information, and other personal data.
Why did the MOVEit breach affect so many organizations?
MOVEit Transfer is widely used software, meaning a single vulnerability in it gave attackers access to data held by every organization using an unpatched version — a "supply chain" attack that multiplies the impact of one flaw across thousands of victims.
How do I check if I was affected by the MOVEit breach?
Because so many different organizations were affected, you may have received a notification letter from a company or agency you have a relationship with. You can also check your email at Scan My Shadow.
Was I notified if my data was part of the MOVEit breach?
Organizations that used MOVEit and had data exposed were generally required to notify affected individuals directly under data breach notification laws, so check your mail and email for notices from companies or institutions you interact with.
