05Reported outcome
38,306,562 accounts are listed in this breach. This is a count of accounts, not necessarily individual people. The reported exposed data includes Dates of birth, Email addresses, Genders, Names, Partial credit card data, Passwords, Phone numbers, Physical addresses.
The passwords in this one were stored as PBKDF2 hashes, which is the thing most companies in this archive got wrong and Canadian Tire got right. It is worth saying plainly, because breach coverage rarely does: a strong, slow hash means the password field is the part of this file least likely to hurt you.
The part that will is the combination underneath it. Name, date of birth, address, phone number and the card type, expiry and last four digits, all in one row. The disclosure notes that bank account information was not affected, which is true and beside the point, nobody defrauds a retail customer by knowing their account number. They do it by calling with the last four digits of the card, the correct expiry, and the customer's own date of birth, which is a script this file writes for them.
Masked card data is classified as low sensitivity because it cannot be used to transact. It can be used to be believed, and that is the attack that follows a retail breach.

What was exposed, and why it matters
Dates of birth
One of the three things call centres ask to verify identity, and it never changes.
Email addresses
The address becomes a confirmed, active target, expect more phishing, better aimed.
Genders
Small on its own; useful to anyone assembling a fuller profile.
Names
Turns an anonymous address into an identified person, which is what makes targeted phishing possible.
Partial credit card data
Not enough to spend, but enough to convince a victim that a caller is genuinely from their bank.
Passwords
Anyone reusing this password elsewhere has those accounts exposed too, credential stuffing is automated and tries them all within days.
Phone numbers
Enables SIM-swap attacks against SMS two-factor codes, and puts the number on scam-call lists indefinitely.
Physical addresses
Where someone actually lives. Combined with a name this moves the risk off the internet.

Three kinds of content appear on this page and they are kept apart deliberately. The breach description is quoted from Have I Been Pwned under its licence. The severity score, the field-by-field explanation and the advice are computed from the record itself, every sentence derives from a number or a flag in it, which is what stops the analysis drifting from the evidence. Anything under the "MyRecon's take" byline is editorial: our reading of this breach, presented as opinion rather than as a finding.
