Adapt.io, a B2B sales-intelligence company that aggregates and sells business contact data, left a database publicly exposed without any password protection in November 2018. Security researcher Bob Diachenko discovered the unprotected server and found it contained over 9.3 million unique records. Adapt did not respond when contacted about the exposure. The exposed records included names, email addresses, phone numbers, physical addresses, job titles, employer information, social media profiles, and company attributes such as organization size and revenue. Most affected individuals had no direct relationship with Adapt and were likely unaware their information had been collected. Because the data was already structured for sales outreach, it required no further processing to be weaponized. No regulatory action or breach notification has been documented in connection with this incident. For those affected, the structured nature of the data creates lasting risk. Attackers can use it to craft convincing spearphishing emails, impersonate executives, and build detailed profiles for business email compromise schemes. People who receive unexpected or highly personalized business outreach should treat it with caution.

B2B sales intelligence platforms aggregate business contact records, company information, job titles, emails, phone numbers, and employer-linked identifiers for lead generation and outbound sales targeting.

Adapt remains an active lead-intelligence platform and continues to market a large global contact database, enrichment tooling, browser extension workflows, and Data OS API products for sales teams. Current public materials emphasize verified B2B data, prospecting automation, integrations, and broad international coverage rather than any major shift away from the core brokered-contact model.
