vldszn··on Binance-hacker-1029 – $5.6B stolen from Binance
Sorry, that is related to Polymarket security incident, missed that.

true, missed this
vldszn··on Binance-hacker-1029 – $5.6B stolen from Binance
UPD: This is related to the Polymarket security incident, not Binance. Sorry, I missed that.

Per Changpeng Zhao (former Binance CEO):

This seems to be caused by DebugBear compromise: https://x.com/debugbear/status/2115866496643535293?s=46&t=_R...

it appears to be an injection attack on the front end. injecting incorrect tx, but showing a valid tx for the user to sign.

vldszn··on Polymarket got hacked
Polymarket:

We've identified & fixed an issue impacting our international platform, Polymarket .com. One of our 3rd party providers was compromised, and we have referred this to relevant law enforcement.

Anyone who has been impacted will be made whole.

Out of an abundance of caution, we have temporarily halted trading & are working to bring the platform back online.

Really cool idea! Will give it a spin.

I’m currently using https://kiwix.org for the offline access to Wikipedia, but your Survival LLM looks even better.

sorry, I thought it might be interesting to see the backstory of the company. I also clearly marked that part of my comment is from ChatGPT.

I can delete my comment, though.
