Hacker claims leak of 1.86 Mn Adda.io records

Housing-tech platform Adda.io is facing scrutiny after a hacker claimed to have leaked data of 1.86 million users, with a 145 MB database circulating on a hacker forum since November 23.

The dump, posted by a user identifying as Blinkers, is linked to an intrusion that allegedly occurred in March 2025, according to breach-monitoring platforms.

The leaked files reportedly contain owner IDs, names, phone numbers, email addresses and MD5-hashed passwords, raising concerns about targeted phishing and credential-stuffing attacks if the hashes are cracked.
