Search Your Email After Reported CRO Booking Leak of 2,189 Pairs
HEROIC analysts reportedly located a file tied to CRO Booking, a travel and accommodation booking platform, holding 2,189 records of email addresses paired with plaintext passwords dated to August 2023. Scanning your email is the only way to find out calmly and quickly whether your booking account details are part of it.
What Was Exposed
Key finding100% of records pair an email address with a password.
Why This Reported Travel Data Deserves Attention
Booking platforms often hold saved travel dates, destinations, and payment preferences. A plaintext password paired with an email gives an attacker an easy, ready-to-use way into that account without having to guess or crack anything.
What This Reported File Reportedly Contains
- Email addresses: confirms a real, reachable contact for follow-up scams or phishing.
- Plaintext passwords: usable immediately to sign in, with no cracking needed on the attacker's part.
Why Travelers Should Treat This Calmly but Seriously
A compromised booking account can be used to view upcoming trip details, change reservation information, or send convincing follow-up messages that look like they come from the booking service itself. None of that requires anything beyond the login pair already in this file. For someone who travels often, a hijacked itinerary can also reveal exactly when a home will be empty, turning a simple password leak into a much bigger personal safety concern.
How a Reported Booking Platform Exposure Like This Unfolds
A reported exposure like this is generally pulled from the booking platform's own account records, not gathered one device at a time. From there, copies tend to move through forums and messaging channels where they are shared further.
Is Your Booking Email Part of the CRO Booking File?
Scan your email to check calmly whether it appears in this reported record. If it does, change your CRO Booking password and update it anywhere else you used the same one, and watch for messages pretending to be from the booking service. Check this for both your personal and any work email you used to book travel.
Data exposed in this breach
Email addresses appear in 100% of the 2,189 records in this breach, alongside plain-text passwords (100%). 100% of records (2,188) 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.

Password Analysis
Key finding2.7% of passwords in this breach are reused, and 40.7% are 8 characters or fewer.
Password strength
Of the 2,188 passwords analysed, 2.7% appear more than once, and the single most common password accounts for 0.3% of them. The average password is 9.1 characters long.
98% contain no special character, 0.1% are numbers only and 0.1% 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 9-10 characters, covering 37.7% of passwords. 40.7% are 8 characters or fewer, while only 0.1% reach 17 characters or more.
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 6 times, and the top 15 together account for 40 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.
