Blockchain technology, with its decentralized, transparent nature, has become a transformative force in various industries.
However, this fact also makes it a potential target for villains. Recently, DEXX attackers have started testing token exchanges for Ethereum (ETH) across EVM (Ethereum Virtual Machine) chains, including Ethereum, Binance Smart Chain (BSC), and BASE.
As disclosed by SlowMist founder Yu Jian, the development signals an increasingly insecure ecosystem.
With one of the attacker addresses, 0xfd01…bb9 publicly revealed, the blockchain community must take note. The transparency of blockchain, while beneficial for tracking transactions, also requires heightened vigilance
This article delves into the significance of this event, its implications for blockchain security, and best practices for protecting digital assets.

What Really Happened? DEXX Attackers Testing EVM Token Exchanges
According to Yu Jian, the founder of SlowMist, a prominent blockchain security firm, DEXX attackers began testing token exchanges for ETH on various EVM chains about 30 minutes before disclosure. The attackers have targeted three of the most-used blockchain platforms: Ethereum, Binance Smart Chain, and BASE.
They exploit vulnerabilities within token swap protocols to divert digital assets for their benefit. Their activities were publicly traceable on DeBank and have been monitored by the community.
On the one hand, this speaks to a strong community effort, while it also sounds an alarm with respect to readiness within these decentralized ecosystems.
Why EVM Chains Are Attractive Targets
EVM chains, such as Ethereum, BSC, and BASE, are in the lead due to their support for smart contracts and dApps. The more adopted and liquid they are, the more hackers would be vulnerable to attacking them.
- High liquidity: The daily flow of billions of dollars in digital assets across EVM-compatible blockchains serves as a significant encouragement to attackers to break security protocols for substantial gains.
- Smart Contract Vulnerabilities: Smart contracts, though revolutionary, can harbor exploitable bugs. Unchecked vulnerabilities allow attackers to manipulate token exchanges.
- Interoperability: The ease of moving tokens between EVM chains can be exploited by malicious actors to cover their tracks, making tracing stolen funds more challenging.
Implications of the Attack
This incident is more than just another security breach—it’s a wake-up call for the entire blockchain industry. Here are the key takeaways:
- Erosion of Trust: Every successful attack undermines trust in blockchain platforms, deterring new users and investors.
- Financial Losses: Apart from the immediate loss of assets, such incidents can lead to broader market instability, affecting token prices and liquidity.
- Regulatory Scrutiny: Increased attacks could invite stricter regulatory oversight, which might stifle innovation in the blockchain space.
The Role of Blockchain Transparency in Combatting Attacks
The transparency of blockchain is both an asset and a weakness. Every transaction is recorded publicly, which permits real-time tracking of suspicious activity. However, without monitoring tools and protocols in place, detecting and mitigating threats becomes problematic.

Platforms like DeBank, which track wallets and transactions, are very instrumental in determining malicious activities. The exposure of the attacker’s address, 0xfd01.bb9, is one of those examples where transparency can help with defense.
However, blockchain users and developers need to be proactive in security to avoid the escalation of such incidents.
Best Practices for Improving Blockchain Security
Due to the ever-evolving threat landscape, blockchain stakeholders need to employ appropriate security protocols:
- Smart Contract Audits: Regular third-party audits can identify and patch vulnerabilities before the attackers take advantage of them.
- Multi-Signature Wallets: requiring multiple authorizations for large transactions adds an extra layer of security.
- Real-Time Monitoring: AI-driven monitoring tools can help detect anomalies in transaction patterns, which helps in responding quickly to a potential threat.
- User Education: Educating users on recognizing phishing attempts and maintaining secure wallets is critical.
What’s the Way Forward? Strengthening EVM Chain Security
The attack is a pointer to the need to have more strengthened security frameworks across all EVM-compatible chains.
Developers and blockchain operators must work together to provide standardized security protocols. Besides, the integration of decentralized insurance models may shield users against financial losses in cases of hacks.
As the blockchain space continues to expand, so does the level of sophistication in attacks. Transparency should be a collective effort that the community will use for both prevention and mitigation.
Conclusion
The DEXX attack on EVM chains was a sobering reminder that DeFi is ultimately insecure. The same transparency inherent in blockchains facilitates both the tracing of illegal flows and requires continuous monitoring and active defense.
With rigorous security measures in place, cooperation between all blockchain participants can be fostered to safeguard the industry against any impending threat and retain users’ trust.
