Reports have surfaced of $25 million in cryptocurrency being stolen.

According to investigators, hackers appear to have chained together bugs and legitimate features from different blockchain technologies to orchestrate a sophisticated "reentrancy attack."

Reentrancy attacks allow hackers to withdraw funds repeatedly, in a loop, before the original transaction is approved or declined.

Oops, that's a major design failure in blockchains. If this is true, blockchain transactions are not ACID compliant. That would mean that all the attempts to use blockchain technologies in real-world financial and business settings are effectively toast.

Bad actors! May a plague of fleas inhabit their underpants.

Fascinating: The Hacker has returned the funds in a different mix of cryptocurrencies.

It's been suggested it was returned because the hacker exposed an IP address.

Really? Serious?
They went through all that trouble and forgot to turn on the VPN?

Hello,

I do not understand well. Whom was stolen? Did they harvest wallets of others? or stole from exchange platforms? or "Virtually" created more coins?
