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 right now
- Be alert for smishing and SIM-swap attempts. Treat unexpected texts and "carrier" calls with suspicion; add a PIN/port-freeze with your mobile carrier.
- Watch for targeted phishing mail. A leaked home address makes postal and doorstep scams more convincing.
- Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
- Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
- Monitor the apps you use going forward. Clearly watches the breach record for the companies behind your apps and alerts you the moment one appears.
