Your Login May Be Caught in Reported Clevedon Breach of 1,154 Accounts
HEROIC analysts reportedly identified a file tied to Clevedon, a membership platform, containing 1,154 records of email addresses paired with hashed passwords dated to August 2023. If you have ever held a membership with this platform, scanning your email is the only reliable way to know whether your record is in it.
What Was Exposed
Key finding11.8% of records pair an email address with a password.
Why You Should Take This Reported Exposure Seriously
Even a hashed password is not automatically safe. Depending on how strong the hashing method is, an attacker with enough time and computing power may still be able to recover the original password and pair it with your email address.
What This Reported Record Pairs Together
- Email addresses: gives an attacker a confirmed, active contact to target directly.
- Password hashes: the underlying strength is not confirmed, so treat any match as a password that could eventually be recovered and reused against you.
Why a Membership Account Is Worth Protecting
Membership platforms often store your name, contact details, and activity history tied to one login. If that login is later cracked and reused elsewhere, an attacker can move from one account into several, building a fuller picture of you along the way.
How a Reported Membership Database Leak Like This Occurs
A reported leak like this usually traces back to the platform's own stored user records rather than something pulled from a visitor's personal device. Once a copy leaves the company, it typically gets passed around on forums and messaging channels well beyond the platform's control.
Does Your Address Appear in the Clevedon Record?
Scan your email to see whether it turns up in this reported file. If it does, change your Clevedon password as a precaution, and change it anywhere else you reused the same one, since hash strength here is uncertain. Do this for both your personal inbox and any work email tied to that membership.
Data exposed in this breach
Email addresses appear in 100% of the 1,154 records in this breach, alongside hashed passwords (88.4%) and plain-text passwords (11.8%). 11.8% of records (136) pair an email address with a password.
An email address and password together are a working login. Attackers feed pairs like these into automated tools that try them on banking, shopping and email sites, so anyone who reused the password elsewhere is exposed there too.

Email providers and account types
76.8% of the email addresses in this breach are personal mailboxes and 23.2% are work addresses. The most common provider is btinternet.com, followed by gmail.com and hotmail.com.
Work addresses matter because a password reused on a company account can give attackers a way into that organisation. The company domains below show which employers appear most often.

Password Analysis
Key finding5.9% of passwords in this breach are reused, and 50.7% are 8 characters or fewer.
Password strength
Of the 136 passwords analysed, 5.9% appear more than once, and the single most common password accounts for 5.9% of them. The average password is 8.9 characters long.
94.1% contain no special character, 2.2% are numbers only and 16.9% are lowercase letters only. Passwords built this way are the first ones cracking tools try, which is why length and a mix of character types matter.
Password habits
Password length
The most common length is 7-8 characters, covering 43.4% of passwords. 50.7% are 8 characters or fewer.
Every extra character multiplies the number of guesses an attacker needs. Passwords of 8 characters or fewer can be cracked quickly once they leak, while long passphrases hold up far better.
Share of passwords by length
- 8 characters or fewer
- 9 characters or more
Most common passwords
The most common password appears 8 times, and the top 15 together account for 23 uses. Passwords are masked here: only their first characters are shown, next to each password's true length.
When many accounts share one password it usually points to a default password, a shared team password or a common pattern such as a name followed by numbers. Treat any password on this list as public.

Password storage and hashing
Of the hashed passwords, 100% use SHA-1. 100% use fast or reversible methods such as MD5, NTLM or SHA-1, which are quick to crack.
Hashing only protects a password if the method is slow. bcrypt, scrypt and Argon2 are designed to slow attackers down; MD5, NTLM and SHA-1 were designed for speed, which makes them easy to crack in bulk.
