pNetwork fell for $13.08M

pNetwork, a Binance Smart Chain based cross-chain protocol fell victim of a codebase level vulnerability, exploiting which an attacker stole 277 BTC, causing the total damage of $13.08 Million.

We're sorry to inform the community that an attacker was able to leverage a bug in our codebase and attack pBTC on BSC, stealing 277 BTC (most of its collateral).

The other bridges were not affected. All other funds in the pNetwork are safe.

Poly Network attack

Developed to address the interoperability of blockchains, Poly Network grew rapidly and locked up around one billion US dollars worth of crypto assets. However, stakeholders were left in shock when more than $600 million USD of cryptocurrency was stolen in a single attack. This left the protocol’s assets under management (AUM) more than cut in half.
