SlideTeam: In April 2021, the “world’s largest collection of pre-designed presentation slides” SlideTeam had 1.4M records breached and later published to a popular hacking forum the following year. Allegedly sourced from a compromised Magento instance, the data included names, email addresses and passwords stored as salted hashes.

Compromised data: Email addresses, Names, Passwords

Verifications.io: In February 2019, the email address validation service verifications.io suffered a data breach. Discovered by Bob Diachenko and Vinny Troia, the breach was due to the data being stored in a MongoDB instance left publicly facing without a password and resulted in 763 million unique email addresses being exposed. Many records within the data also included additional personal attributes such as names, phone numbers, IP addresses, dates of birth and genders. No passwords were included in the data. The Verifications.io website went offline during the disclosure process, although an archived copy remains viewable.

Wanelo: In approximately December 2018, the digital mall Wanelo suffered a data breach. The data was later placed up for sale on a dark web marketplace along with a collection of other data breaches in April 2019. A total of 23 million unique email addresses were included in the breach alongside passwords stored as either MD5 or bcrypt hashes. After the initial HIBP load, further data containing names, shipping addresses and IP addresses were also provided to HIBP, albeit without direct association to the email addresses and passwords. The data was provided to HIBP by a source who requested it be attributed to “[email protected]”.

Gravatar: In October 2020, a security researcher published a technique for scraping large volumes of data from Gravatar, the service for providing globally unique avatars . 167 million names, usernames and MD5 hashes of email addresses used to reference users’ avatars were subsequently scraped and distributed within the hacking community. 114 million of the MD5 hashes were cracked and distributed alongside the source hash, thus disclosing the original email address and accompanying data. Following the impacted email addresses being searchable in HIBP, Gravatar release an FAQ detailing the incident.
