Rekt - False Prophet
DeFi / Crypto - Alpaca Finance lost millions by allegedly using manual CoinGecko price updates instead of real oracles. When questioned, they asked "which faster oracle would you have used?" Turns out F5 isn't a reliable price feed. Who knew?

Feel free to use this folder to onboard your non-web3 friends to Web3, as the majority of the channels are maintained by independent researchers. There are also additional channels for news, CT reviews, and more!
A small tip to subscribooors: if you find a channel interesting, move it out of the folder into your main list of chats. That way you’ll view content you’re interested in more often, and channels get more views instead of just subscribers!

DeepSeek has been hacked: all of their data in the public domain - secret keys, unencrypted chats, logs, and even the backend.
Researchers from wiz.io were performing a normal infrastructure check when they unintentionally uncovered a database that is fully open, allowing anyone to obtain access.
