Mailbox access
A working login to a corporate or personal mailbox, sold as access rather than as a password. The buyer reads, replies and resets other accounts from inside a mailbox its owner is still using.
Why it matters to you
A mailbox is the recovery channel for everything else, so its compromise is not one account, it is all of them. Forwarding and rule audits catch what a login alert does not.
Where we meet it
Mailbox listings quote the domain type and the country rather than the address. A rise in listings naming your sector is a hiring signal for whoever is preparing the invoices.
Connected terms
Business Email Compromise (BEC)
Fraud committed from inside a real mailbox: the attacker reads the thread, waits for an invoice and answers it with different bank details. No malware, no attachment, nothing for a scanner to find.
Stealer log
The complete output of an infostealer infection: every saved browser password, session cookie, autofill record and crypto-wallet file from one victim machine, zipped into a single bundle.
Session cookie
The token that proves a browser is already logged in, copied straight out of a victim's browser by an infostealer. Replayed elsewhere it opens the account without the password and without a second factor.

Knowing the word is the cheap half. The platform is the half where the term arrives attached to your domain, with a timestamp and the source it came from.
More from the goods
Bank log
Access to a compromised online banking account, sold with the balance quoted in the listing. Priced as a fraction of what it holds, because the buyer still has to get the money out.
BIN
The first six to eight digits of a payment card, identifying the issuing bank, the country and the card product. Not stolen data in itself, but the index the trade is organised around: cards are advertised, sorted and priced by BIN.
Card dump
The magnetic-stripe data read off a payment card, sold for cloning into a physical one. Distinct from card-not-present data, priced higher, and slowly becoming a legacy good as chip and contactless spread.
Combolist
A recycled email:password list compiled from old breaches and other people's logs, resold in bulk. The fast food of the credential economy: cheap, stale, everywhere.
