Not all hackers are criminals. In the world of cryptocurrencies, there are so-called “#hackers white hat hackers,” experts who find vulnerabilities… but instead of stealing funds, they alert developers and, in many cases, prevent multimillion-dollar losses.

Here we tell you the most surprising cases.

🛡️ What is a white hat hacker?

They are cybersecurity experts who test systems for flaws, but they do so ethically, reporting errors and sometimes receiving rewards known as “bug bounties.”

💥 Real Cases where White Hats Saved the Day

1️⃣ Poly Network (2021): $610 million returned

One of the largest hacks in history. An attacker stole $610 million from the DeFi platform #poly Network… but turned out to be an ethical hacker. After demonstrating the vulnerability, they returned all the money, claiming that their intention was to expose the flaws.

2️⃣ Wormhole Bridge (2022): $320 million leak avoided

A hacker discovered a critical breach in the Wormhole bridge, which connects blockchains like $ETH y $SOL . Thanks to their quick report, the flaw was fixed before funds were stolen.

3️⃣ Aurora Protocol (2022): $200 million protected

The security researcher pwning.eth found a vulnerability in #AURORA that could have allowed for a massive theft. The platform rewarded them with $6 million, avoiding a tragedy.

4️⃣ MakerDAO and multiple silent rescues

MakerDAO and other protocols have consistently paid rewards to ethical hackers who discover flaws before malicious attackers exploit them.

🎯 Why do ethical hackers matter?

  • They protect the critical infrastructure of DeFi.

  • They prevent people from losing their funds.

  • They encourage the development of more robust systems.

  • They are invisible allies in the security of the crypto ecosystem.

💬 Conclusion

In the wild west of cryptocurrencies, not everything is chaos. Thanks to white hat hackers, projects are strengthened, and users are more protected.

👁️‍🗨️ In initiatives like #BitValue , where data is turned into value, security is a priority. Collaboration with the community of ethical experts ensures that the ecosystem remains trustworthy and accessible to all.
