What happened
In approximately mid-2020, Mashable suffered a data breach. The data turned up publicly in November 2020, and Have I Been Pwned added it to its database on 10 November 2020. It holds 1.4 million unique email addresses.
According to news coverage of the leak, the database was tied to an old feature that once let readers sign in with a social media account. Mashable said the feature was no longer in use. Mashable also temporarily disabled access to the affected accounts.

What was exposed
The data includes email addresses, names, genders, physical locations, IP addresses, links to social media profiles, expired auth tokens, and the day and month of birth (but not the year). Auth tokens are the codes a site hands out after you sign in with another service. These ones had already expired, so they shouldn't let anyone into your accounts.
What it lets criminals do
No password data is listed in the breach, so there's little to take over directly. The risk is targeted phishing. An email address, a name, a city and a social media profile are enough for a message that looks personal, such as a fake Mashable account notice or a prize offer. A day and month of birth also helps someone guess security answers or pass a weak identity check, so treat questions about your birthday with some suspicion.
What to do
You don't need to panic over this one, but it's worth a few minutes. Be careful with emails that mention Mashable or your social media login, and check which other breaches your email appears in.
What to do if you were in it
- 1
Expect phishing that looks personal
Messages may use your real name, city or social profile. Don't click links in unexpected emails about Mashable or your accounts. Go to the site yourself.
- 2
Review the social accounts you linked
If you ever used a social media account to sign in to Mashable, open that account's connected apps list and remove anything you no longer use.
- 3
Don't reuse your birthday as a security answer
The day and month of birth leaked. If a bank or other account uses your birthday for recovery, switch to a different method.
