What happened
In mid-2021, Risk Based Security reported that a database from the conservation group Ducks Unlimited was being traded online. Have I Been Pwned says the data dated back to January 2021 and held 1,324,364 unique email addresses across a membership list and a list of website users. It was added on 16 November 2021.

What was exposed
The data included email addresses, names, phone numbers, physical addresses, dates of birth and passwords. The passwords were stored as unsalted MD5 hashes, which are quick to crack.
What it means for you
This is a fuller profile than most account leaks. A name, home address, phone number and date of birth together are what scammers need for convincing phishing and for pretending to be you with a phone carrier or a bank. A scam that mentions a membership or website account you really had will look believable, because the data came from those lists. If you reused your password, change it everywhere.
Risk Based Security's June 2021 report is the source Have I Been Pwned cites for this incident.
What to do if you were in it
- 1
Change your password, and any reuse of it
Change your Ducks Unlimited password, then change it on every other account where you used the same or a similar one. Use a password manager so each account gets a unique password, and turn on two-factor login where it's offered.
- 2
Expect phishing that mentions the breach
Scammers use leaked email addresses and phone numberses to send convincing messages. Don't click links in unexpected emails or texts about your account, and go to the site directly instead.
- 3
Watch for identity theft
Your date of birth and address may be exposed. In the US, consider freezing your credit at Equifax, Experian and TransUnion (it's free), and check your statements for accounts or charges you don't recognise.
- 4
Be wary of calls and texts
With your phone number and address in the data, callers may sound like they know you. Hang up and call back on a number from the organisation's official site.
