Relay Protocol's contracts trusted Ed25519 verification without validating offsets, opening the door to forged allocator signatures and potential double-spends. Learn about the bug, the risks it posed to cross-chain liquidity, and how the issue was addressed.
A new instruction broke the flash loan logic, creating a way to borrow without repaying and putting $160M at risk. We explain the vulnerability, potential impact, and how it was fixed.
In the year 2050, a malformed JSON input lead to the complete shutdown of the Replicant P2P network. Today, we'll reproduce this bug class in ~100 lines of code.
Cross-program invocation (CPI) is the mechanism on Solana through which one program calls another. It's used for system instruction calls, SPL token transfers, custom program execution, and even event emissions, making it a core part of writing functional programs in Solana.
This blogpost details a vulnerability identified in Titan's Helix MEV Relay which could be abused by trusted proposers to perform equivocation attacks, during which private transaction information is prematurely revealed, leading to potential transaction reordering.
In this blog post, we will show how a small difference in SSZ deserialization between the Prysm and Lighthouse clients could have allowed an attacker to severely degrade Ethereum consensus.
We privately disclosed a vulnerability to Circle via their bug bounty program. The vulnerability could have been exploited by circumventing the CCTP message sender verification process to mint fake USDC tokens on Noble.
This post details a vulnerability we identified in Evmos, an EVM-compatible Cosmos chain, that could have been exploited to mint infinite amounts of $EVMOS tokens. Due to EVM state commits during precompile execution, it could cause a mismatch between the state held within EVM and the Bank module.
This post discusses a vulnerability in ibc-go, a reference implementation of the Cosmos Inter-Blockchain Communication (IBC) protocol. A reentrancy vulnerability during the handling of timeout messages could have allowed an attacker to mint an infinite amount of IBC tokens on affected Cosmos chains.
In this post, we describe a vulnerability in Heimdall, the validator software of the Polygon Proof-of-Stake (PoS) blockchain. This flaw, if exploited, could have allowed a rogue/compromised validator to take over the Heimdall consensus layer and inject fraudulent events into the StakeSync mechanism.
