7 Additional Costs of Getting Hacked: Beyond the Financial Fallout

In March 2023, the DeFi protocol Euler Finance experienced a devastating hack that initially saw some $200 million siphoned by the hacker. Miraculously, within a few weeks, the hacker returned the stolen funds, allowing a full financial recovery for all of Euler’s users. At first glance, it might seem like the damage was limited and the protocol dodged a bullet. 

Similarly, there have been cases where the amount stolen was relatively low, leading some to question if the overall impact is minor as well. However, the reality is far more nuanced. What are the other, less visible costs of such a breach? Beyond the immediate financial loss, a hack can have profound and lasting impacts on a protocol's reputation, user trust, operational focus, and team morale. This article delves into these hidden costs.

1. The Financial Sting

The immediate financial loss from a hack is often the most visible impact, drawing significant media attention and user concern. Even when most of the funds are returned, as in the case of Euler, the initial shock can cause panic among users and investors. The value of the protocol's token may plummet  - in Euler’s case it lost almost 70% of its value in the days following the hack - and liquidity can dry up as users rush to withdraw their assets. While these financial repercussions are substantial and damaging, they represent just one dimension of the overall impact.

2. Reputation in Ruins

A security breach can quickly erode a DeFi protocol's hard-earned trust and reputation. In the unforgiving world of DeFi and web3, user trust is paramount. When Euler was hacked, despite the return of most funds, users were left questioning the protocol's security measures and the team’s integrity. Social media platforms and community forums were flooded with negative sentiments, leading to a significant drop in user engagement. Additionally, potential users who search for Euler online will encounter numerous articles and posts about the security incident, which will dominate the top search results long into the future. Rebuilding this trust is an arduous process, often taking months or even years, and requires substantial investment in security upgrades, transparency initiatives, and community outreach.

3. Psychological Impact on Users

Beyond the financial implications, the psychological impact of a DeFi hack on users can be devastating. The sudden realization that their assets are compromised can lead to severe emotional distress, including fear, anger, and a profound sense of betrayal. Users may experience anxiety and stress, doubting the security of their investments and feeling powerless in the face of sophisticated cyber threats. This erosion of confidence can result in decreased participation in DeFi platforms and reluctance to adopt new technologies.

4. The Productivity Black Hole

When an exploit occurs, it triggers a frantic all-hands-on-deck response from the affected protocol’s team. Engineers, developers, and management must immediately shift their focus to crisis management, dedicating countless hours to identifying the breach's cause, patching vulnerabilities, and communicating with users. This emergency response consumes incredible resources and diverts attention from planned projects and growth initiatives. Development of new features often comes to a halt, and roadmap milestones are significantly delayed. The opportunity cost of this diversion is substantial, as innovative projects are shelved and the protocol's competitive edge in the rapidly evolving DeFi landscape diminishes.

5. Impact on Ecosystem and Partners

The ripple effects of a hack extend beyond the immediate protocol and its users. Partner projects, liquidity providers, and associated DeFi platforms can also suffer. In Euler’s case, many protocols, including Balancer, Idle, and Yield, were directly impacted. Yield’s overcollateralized stable coin suffered a depegging event due to the losses it suffered. Trust in the broader DeFi ecosystem can erode, leading to a decline in overall market confidence and activity. This interconnectedness, which can be viewed as one of Defi’s strengths, means that a single breach can have far-reaching consequences, impacting numerous stakeholders.

6. The Legal Minefield

Beyond the immediate operational and reputational damage, a security breach can plunge a DeFi protocol into a complex legal landscape. Regulatory bodies and other government entities may scrutinize the protocol's compliance with financial regulations, potentially leading to fines and sanctions. Legal liabilities can arise from failing to safeguard user funds adequately, and there might be lawsuits from affected users. The lack of clear regulatory frameworks in the DeFi space can make navigating these challenges even more daunting. 

7. The Culture Shock

A hack can shatter morale and cultural integrity within a protocol's team. The stress and pressure of dealing with a security breach can lead to burnout and a loss of motivation among team members. If not proactively addressed, these issues can linger, affecting productivity and innovation long after the initial crisis has passed. Rebuilding a positive team culture and restoring confidence in the protocol's mission requires strong leadership and a clear commitment to improve security practices.


While the financial losses from hacks are painful, they are just the beginning. The broader impacts on reputation, productivity, legal standing, and team morale are significant and enduring. For many protocols, an exploit with even mild financial outcomes can pose an existential risk. Even if the immediate financial losses are mitigated, a major security breach can spark a crisis of confidence among users and investors. In the wake of a hack, users may rush to withdraw their assets, causing liquidity to dry up and trading volumes to plummet. This mass exodus can severely damage the protocol's market position and lead to a significant loss of trust.

Preventing such incidents through robust security measures is far more effective than trying to respond to and recover from them. This underscores the critical need for investing in sophisticated, proactive security measures.
