Just five days after the decentralized finance platform Drift Protocol suffered a $270 million exploit at the hands of a North Korean state-affiliated group, the Solana Foundation has announced a suite of security initiatives. The Drift Protocol exploit was carried out following a six-month social engineering campaign.
The centerpiece of the Solana Foundation's security overhaul is Stride, a structured evaluation program led by Asymmetric Research. Stride will assess Solana DeFi protocols against eight security pillars and publish its findings publicly. Additionally, the foundation has introduced the Solana Incident Response Network (SIRN), a membership-based group of security firms and researchers focused on real-time crisis response.
While the initiatives address part of the problem exposed by the Drift exploit, they do not address the root cause of the loss. The vulnerability that led to the exploit was human in nature: the attackers spent six months building relationships with Drift contributors and compromised their devices through a malicious code repository and a fake TestFlight app.
Under the Stride program, protocols with more than $10 million in total value locked (TVL) that pass the evaluation will receive ongoing operational security and active threat monitoring funded by Solana Foundation grants. The coverage will be calibrated to each protocol's risk profile. For protocols with more than $100 million in TVL, the foundation will also fund formal verification, a mathematical method that checks every possible execution path in a smart contract to guarantee correctness. The founding members of SIRN include Asymmetric Research, OtterSec, Neodyme, Squads, and ZeroShadow.
The network is available to all Solana protocols but prioritized by TVL. It is worth noting that Stride's formal verification would not have caught the North Korean attack, which used the compromised devices to obtain multisig approvals that were then locked into durable nonce transactions and executed weeks later. Similarly, 24/7 monitoring of onchain activity would not have prevented the attack, as the transactions were valid by design and indistinguishable from legitimate administrative actions until they were used to drain the vaults.
The attack exploited the gap between onchain correctness and offchain human trust, a gap that no smart contract audit or monitoring tool is built to cover. However, SIRN could have potentially helped with the response to the attack. Onchain security expert ZachXBT criticized stablecoin issuer Circle Internet (CRCL) for failing to freeze over $230 million of its stolen dollar-pegged USDC during a six-hour window after the attack began. A dedicated incident response network with established relationships to bridge operators, exchanges, and stablecoin issuers might have shortened the response time.
Whether it would have been fast enough to prevent the Wormhole bridging and obfuscation through Tornado Cash is an open question. The Solana Foundation emphasized that the programs 'do not transfer the underlying responsibility away from the protocols themselves,' a statement that takes on a different meaning after Drift's postmortem revealed that individual contributor devices were the entry point for a nation-state attack.
Solana already hosts several free security tools for builders, including Hypernative for threat detection, Range Security for real-time monitoring, and Neodyme's Riverguard for attack simulation.
