What happened
In early 2024, a large corpus of data from DemandScience (a company owned by Pure Incubation), appeared for sale on a popular hacking forum. Later attributed to a leak from a decommissioned legacy system, the breach contained extensive data that was largely business contact information aggregated from public sources. Specifically, the data included 122M unique corporate email addresses, physical addresses, phone numbers, employers and job titles. It also included names and for many individuals, a link to their LinkedIn profile.

What to do if you had an account
- Turn on two-step sign-in. Enable two-factor authentication where the service offers it, preferably with an authenticator app or a passkey. A leaked password alone is then not enough to get in.
- Expect targeted phishing. Leaked contact details are used to write convincing fake messages that mention the breached company or your real name. Do not click links in unexpected emails or texts about this account; go to the site by typing its address.
- Watch for scam calls and SIM swaps. Be suspicious of calls and texts that claim to be from your bank or a courier. Ask your mobile operator for a port-out or SIM-change PIN if it offers one.
