On 31 May, EOS launched a bug bounty program on HackerOne and asked for reports on vulnerabilities impacting EOSIO blockchain software and Eos.js libraries.
The company offered a minimum bounty of $10,000, a financial reward that bug bounty hunter Guido Vranken is enjoying.
The ethical hacker reported a number of vulnerabilities in the core EOSIO software, earning him $80,000 in one day. However, additional bugs have been submitted, which Vranken believes tallies up to a total of $120,000.
Due to the bug bounty hunter's success, the startup offered Vranken a permanent role, although there is no information available on whether or not the job has been accepted.
The Cayman Islands-based startup managed to raise $4 billion during its ICO, despite the lack of a live product.
Vranken is evidently skilled at finding bugs, but the fact that one individual was able to find at least 12 vulnerabilities in one week while working alone suggests that EOS should take its code more seriously.
If it does not, the ICO, funding, and hype around its decentralized projects could all end up neutralized with one successful attack or data breach.
In related news, consultancy Autonomous NEXT said this week that while cryptocurrency startups have managed to raise close to $9 billion in ICOs over the course of this year alone, the hype is beginning to fade.
"If we pull out Telegram and EOS on a monthly basis, the monthly trend look severely down -- to $560 million from a high of $1.5 billion in December 2017," Autonomous NEXT said, as reported by Business Insider. "So unless you believe in the continued presence of mega deals, token offerings have indeed been dragging due to continued regulatory uncertainty, tax overhang, and a lack of tangible progress in software adoption by the mainstream consumer."
