What happened in Have I Been Pwned’s words
In October 2017, the genealogy website MyHeritage suffered a data breach. The incident was reported 7 months later after a security researcher discovered the data and contacted MyHeritage. In total, more than 92M customer records were exposed and included email addresses and salted SHA-1 password hashes. In 2019, the data appeared listed for sale on a dark web marketplace (along with several other large breaches) and subsequently began circulating more broadly.
