### Hacker claims to leak WIRED database with 2.3 million records

An attacker claims to have breached Condé Nast, an American media company. The attacker claims to have 40 million additional records for other properties. The post didn't specify but this could potentially include names like The New Yorker, Ars Technica, Vogue, Vanity Fair, and more. Data includes subscriber's unique internal ID and email address. Other data was optional - like name, phone number, physical address, and birthday. The article says many of these were left empty.

### Exploited MongoBleed flaw leaks MongoDB secrets, 87K servers exposed

A new massive vulnerability (8.7 out of 10) in MongoDB has been revealed - including a proof-of-concept - putting tens of thousands of servers at risk. Fixes were already released ten days ago but given the holidays (and the general track record of these things) I'm sure we can expect to see a lot of companies showing up in these weekly updates for the next several weeks.

### Trust Wallet confirms extension hack led to $7 million crypto theft

A compromised Chrome extension update released on December 24 allowed attackers to steal funds. Trust Wallet has said they will cover the cost to users and are investigating further. Attackers (potentially unrelated) also launched phishing domains around the same time promising a patched version of the extension but would actually steal more funds. This is a reminder to use only trusted, custodial wallets such as Cake Wallet (ideally with Monero).
