On April 26th, the Solana DeFi protocol Loopscale was hacked for over $3 million. This breach resulted in a loss of approximately $5.8 million in NFTs. Unfortunately, this exploit has directly impacted Loopscale users. It has led to some much-needed conversations around security and risk management practices within the burgeoning decentralized finance (DeFi) ecosystem. MetaBlock X is prepared to run through the nitty-gritty of the attack and what it means. We’ll be discussing what they can do to protect themselves in the future, both users and developers.

Hacker Willing to Return Stolen Funds

Following the exploit, news circulated that the hacker was willing to refund some of the stolen funds. This surprising turn of events surprised just about everyone. This unfortunate reality is a common experience for negotiators in DeFi hacks. Attackers on occasion prefer to have stolen funds returned in return for a “bug bounty” or to avoid domestic prosecution. In any case, the terms of any potential settlement between Loopscale and the hacker remain murky at best. All is not lost for impacted users, as they can potentially get back at least some of their missing assets.

Details of the Agreement

The fine print is scant, but these agreements typically involve the hacker returning most of the pilfered money. In return, they take a cut as their incentive. This is a win-win for supporters and hurdlers alike. While the hacker keeps the proceeds from their exploitation of that vulnerability, the protocol can use the assets it recovers to help make things right. Don't underestimate the fact that these negotiations are tricky, sometimes impossible and often fraught with a lack of success.

Implications for Future Security

The hackers’ willingness to negotiate only puts a finer point on the need to have strong incident response plans ready, before you need them. Plan guidelines to not only respond to attackers, but prosecute them successfully. Evaluate the chances of recouping taxpayer dollars and negotiate terms that are advantageous to both the platform and the platform’s users. This approach may not compensate for all losses, but it is a critical start in showing good faith efforts to make things right.

How the Exploit Happened

The Loopscale exploit was all about baiting on RateX collateral price depreciation. According to Mary Gooneratne, co-founder of Loopscale, the hacker siphoned 1200 SOL and $5.7 million USDC from the protocol’s vaults. They accomplished that by borrowing a string of undercollateralized loans. This section will explore the mechanics of the attack. We’ll go further to share how the pricing manipulation occurred and point out the exact vulnerabilities that hackers exploited to wreak havoc.

Overview of Pricing Manipulation

The heart of the attack was the manipulation of RateX PT token pricing functions. RateX, a protocol based on Solana’s ecosystem, enables users to trade de-risked fixed-rate loans. The platform’s algorithms decide how much each loan will cost. They rely on accurate door-to-door data feeds and the latest market conditions. We’ve seen an attacker exploit user-defined pricing functions to pump up the value of their collateral as high as it’ll go. This neat little trick allowed them to get loans that were minisculely undercollateralized.

Technical Breakdown of the Attack

The attacker took advantage of a bug in the way Loopscale priced RateX-based collateral. This loophole provided them an opportunity to game the system. They artificially inflated the perceived value of their collateral far beyond its true market value. The attacker exploited this oversight and borrowed orders of magnitude more USDC and SOL than permitted. This irresponsible move all but emptied the treasury’s coffers. Investigators are continuing to analyze the technical details behind the exploit. It looks like a sophisticated interplay between the price oracles and the lending protocol’s smart contracts.

Loopscale’s Reaction to the Incident

In light of the exploit, Loopscale quickly initiated damage mitigation strategies to safeguard remaining funds. In response, the protocol temporarily shut down its lending markets. Recently, it has begun to reopen some facilities and is still working on a long-term recovery plan. This chapter will dive into the short-term strategies used by Loopscale during this golden window. Perhaps more importantly, it will focus on how they engaged, informed and educated their users.

Immediate Actions Taken

Loopscale’s initial reaction was to quickly stop all Loopscale lending markets to avoid future manipulation. This move brought the platform to a full halt, stopping the attacker from being able to drain any more funds. Within a few hours the protocol was again able to reactivate loan repayments and loan top-ups. This change helped users better close loops and handle their current/open positions. Vault withdrawals continued to be limited. During this time, the team continuously evaluated the impact of the damage and created a plan that would allow the platform to be restored.

Communication with Users

Transparency and a consistent message are particularly important in a crisis of this nature. Loopscale has pledged to disclose how many users were impacted. They will share information about how holders can withdraw from their vaults, as well as a more detailed technical post-mortem of what exactly caused the exploit. Keeping users informed about the progress of the investigation, the recovery plan, and the steps being taken to prevent future attacks is essential for maintaining trust and confidence in the platform.

Rising Incidents of DeFi Security Breaches

Unfortunately the Loopscale hack is not an outlier. The DeFi space has seen a surge in security breaches in recent years, highlighting the inherent risks associated with decentralized finance. Read on for a look at some recent high-profile attacks and their contribution to a growing toxic environment imperiling the entire DeFi space.

Recent Examples of Attacks

Just one example of a high-profile DeFi hack that’s made headlines in recent months, each affecting a different protocol and exploiting different vulnerabilities. The attacks have led to hundreds of millions of dollars lost and weakened public confidence in the DeFi sector. High-profile case in point breaches have hit cross-chain bridges, lending protocols, and decentralized exchanges to name just a few. Each attack makes necessary the continuing demand for vigilance. The DeFi community dons a real reputation booster by adopting and implementing comprehensive security standards throughout the DeFi ecosystem.

Impact on the DeFi Ecosystem

The impact of these security breaches on the DeFi ecosystem are staggering. They contribute to considerable financial harm to users, but wreak havoc across the reputation of the entire industry. The ever-looming threat of hacks makes it hard to bring new users into the space. It steepens the learning curve for prospective users and discourages existing users from investing further in DeFi protocols. Only by addressing these security concerns can the DeFi ecosystem grow and flourish sustainably in the long run.

Steps Towards Recovery and Resolution

Loopscale is actively developing a plan to recover the stolen funds and bring the platform back to full functionality. In this final installment, we’ll go over what’s being done to recover their stolen funds and when the platform may return to operation.

Plans for Fund Recovery

Loopscale is currently in pursuit of many ways to recoup the stolen funds. At the same time, they are negotiating with the hacker, working with law enforcement, and readying to take legal action. The impacts of these efforts depend heavily on three things. Crucial among them are the hacker’s cooperation and our capacity to follow the stolen money.

Timeline for Platform Restoration

Loopscale has still not given a concrete timeline of when they will be able to get the platform fully working again. The team has stated that they are working diligently to address the vulnerabilities that were exploited and implement enhanced security measures. As soon as we’re able to put these into action, the platform returns to full function. We’ll start by bringing vault withdrawals back online, as well as other core features.

Insights from the DeFi Crisis Response

The Loopscale hack provides important lessons for DeFi protocol developers and users alike. Analyzing the incident and its response can identify lessons learned. These learnings continue to guide us in determining best practices around security, risk management, and incident response to malicious activity.

Key Takeaways for Developers

The Loopscale hack should be an alarm bell to developers. It underscores the importance of code audits, extensive testing, and ongoing smart contract monitoring. Another attack surface that needs to be addressed is developer behavior. They need to adopt multi-signature wallets, real formal verification techniques, and even create bug bounty programs.

Recommendations for Users

For users, the Loopscale hack is an important reminder of the risks that come with DeFi investing. As always, do your own research before investing in a protocol. Know what you’re getting into, and be sure to keep a diverse mix in your portfolio. As a general rule, watch out for anything that promises returns that seem too good to be true. They just happen to be more vulnerable to exploits. Keep your finger on the pulse of emerging security threats and vulnerabilities. Protect your accounts. Take action to protect yourself, starting by creating strong passwords at each account and enabling two-factor authentication (2FA).
