Manga Traders data breach: 855K accounts exposed
Severity: high · Patch status: no-fix-needed · Since 2014-06-10
In June 2014, the Manga trading website Mangatraders.com had the usernames and passwords of over 900k users leaked on the internet (approximately 855k of the emails were unique). The passwords were weakly hashed with a single iteration of MD5 leaving them vulnerable to being easily cracked. Exposed data: email addresses, passwords. The breach dates from Jun 9, 2014; Have I Been Pwned loaded it on Jun 10, 2014.
What to do
- If you had a Manga Traders account, change its password and the password of any other account that reused it.
- Turn on multi-factor authentication wherever it is offered.
- Check whether your addresses are in this breach at https://haveibeenpwned.com.
- Expect targeted phishing that quotes the leaked details; verify any unexpected contact out of band.
