Data & Leads data breach: 44.3M accounts exposed
Severity: medium · Patch status: no-fix-needed · Since 2018-11-28
In November 2018, security researcher Bob Diachenko identified an unprotected database believed to be hosted by a data aggregator. Upon further investigation, the data was linked to marketing company Data & Leads. The exposed Elasticsearch instance contained over 44M unique email addresses along with names, IP and physical addresses, phone numbers and employment information. No response was received from Data & Leads when contacted by Bob and their site subsequently went offline. Exposed data: email addresses, employers, ip addresses, job titles, names, phone numbers, physical addresses. The breach dates from Nov 14, 2018; Have I Been Pwned loaded it on Nov 28, 2018.
What to do
- If you had a Data & Leads 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.
