The Preen.Me Breach Exposed More Records Than a Mid-Size City Has People

HEROIC analysts found the Preen.Me dataset on September 3, 2024. The breach traces back to a ransom attack against Preen.Me, a social media marketing company based in the United States, that occurred in May 2020. That incident resulted in the exposure of 229,104 records containing email addresses, password hashes, usernames, first names, and last names. The data surfaced publicly more than four years after the original attack, a gap that indicates the records were retained and later redistributed through underground channels.

Although no plaintext passwords are present, the password hashes in this dataset carry real risk. If the hashing algorithm used was weak or unsalted, attackers can crack a significant portion of those hashes using precomputed lookup tables or GPU-accelerated tools. The combination of full names, email addresses, and usernames in a single record makes each entry highly usable for targeted phishing, account enumeration, and social engineering attacks against affected individuals.

What Was Exposed

• Email Address
• Password Hash
• Username
• First Name
• Last Name

Why This Matters

Password hashes are not the same as plaintext passwords, but they are far from safe. Attackers with access to hashed passwords routinely run them through hash-cracking tools that can test billions of combinations per second. Common and reused passwords fall quickly. Once cracked, those passwords feed into credential stuffing campaigns targeting email providers, banking platforms, and any other service where the same password may have been reused. The full names and email addresses in this dataset also enable targeted phishing messages that appear credible because they include accurate personal details. Identity theft and unauthorized account access are direct downstream risks from this type of exposure.

How Database Breaches Work

A database breach occurs when an attacker gains unauthorized access to the backend systems storing user records. In the case of Preen.Me, a ransom attack in May 2020 gave the attacker access to the underlying user database. During ransom attacks, threat actors frequently copy the data before encrypting systems or making demands, giving them a second commodity to sell or release if the ransom is not paid. The extracted database is then packaged and distributed through dark web forums and marketplaces, sometimes immediately and sometimes years later, as happened here with the September 2024 public appearance of data from a 2020 incident.

Check If You Are Affected

HEROIC's free breach scanner checks your email address against more than 400 billion records, including the Preen.Me dataset. If your email appears in this breach, update any passwords associated with that account and any other accounts where you reused the same password. Enable two-factor authentication on your most sensitive accounts to limit exposure even if a password has been compromised. Run a free scan at HEROIC to see where your data has appeared across all known breach data.
