737 crypto accounts were drained last night of approximately $2.73 million dollars in the span of one hour. Polymarket confirmed a third-party vendor they used was compromised, which is suspected to be DebugBear, a website monitoring service. This led to legitimate blockchain withdrawals being processed as logged-in users were spoofed by threat actors.
Welcome back to Friday Financial Foolishness and today we’re going to be talking about arrogance, security, and risk mitigation.
Earlier in April a Twitter user by the name of Dark Web Informer claimed that Polymarket was breached and the information of 300k+ users was leaked on a cybercrime forum. This led to community responses and Polymarket laughing in their reply because it is a feature of blockchains. Your submitted identity must be verified in every transaction without exception.
Now as another user vx-underground pointed out, this was likely a phishing attempt for information and Polymarket really shouldn’t taunt unknown threat actors for the sake of their business and clients.
Setting aside the insanity of being a cryptocurrency trader on a gambling, sorry ‘prediction’ platform, this was a completely preventable occurrence from multiple standpoints.
If you’re going to trade cryptocurrency, do so with protection. If you do not own the wallet, that is not your crypto. It is merely loaned to you by your market platform who hopefully won’t do something stupid and lock you out of it, see example Sam Bankman-Fried of FTX
And if you’re a business, especially being an intermediary for money, maybe don’t spit in the face of strangers. There was no positive return for them in doing so and now they’re out at least $2.73 million dollars. This is just like Kelly Clarkson and the Art of Play, only now at a grander scale with real world implications.
None of this would have happened if they were invested sensibly on a properly regulated platform. Don’t go to casinos that taunt criminals, it’s bad for your health. And don’t engage in speculative trading without proper protection, it’s bad for your wallet.
