In a fascinating turn of events, a crypto user known as Michael recently enlisted the help of cybersecurity researchers Joe Grand and Bruno to recover 43.6 bitcoins that he had lost access to 11 years ago. The process involved hacking time and reverse engineering the password generator used to create the password for the wallet holding the valuable assets. Despite the complexity of the task, their perseverance paid off as they successfully regained access to the wallet and retrieved the lost coins.
The Security Paranoia of Michael
Michael’s story is one characterized by a deep sense of security paranoia. Back in 2013, he set up a wallet to store his bitcoins and used RoboForm to generate a unique password. However, instead of storing the password directly on RoboForm, he opted to keep it in an encrypted file for added security. Unfortunately, this decision came back to haunt him when the encrypted file became corrupted, leading to him losing access to the wallet and the valuable bitcoins within.
Initially reaching out to Grand in 2022 with no success, Michael refused to give up and tried again in June 2023. This time, he caught Grand’s attention, and together with Bruno, they embarked on the challenging task of retrieving the lost assets. The duo’s investigation unearthed a vulnerability in RoboForm’s random number generator, linking each generated password to the specific date and time it was created on a user’s computer. Despite the vulnerability being patched in 2015, they deduced that it could have impacted passwords created before the fix.
After Mike recalled the date he created the password – April 13, 2013 – Grand and Bruno set out to test hundreds of passwords within the time parameters. Their arduous efforts eventually paid off when they correctly identified the password created on May 15, 2013, granting them access to the wallet and the lost bitcoins. Grateful for their assistance, Michael shared a portion of the retrieved stash with Grand and Bruno when bitcoin’s value was around $38,000. As the price of the asset continued to climb, he decided to sell some for himself, while still holding onto 30 bitcoins worth approximately $2 million, awaiting a potential surge to $100,000.
The journey to recover lost bitcoins is a testament to the intersection of cybersecurity expertise and unwavering perseverance. Through meticulous investigation and innovative problem-solving, Grand and Bruno were able to help Michael reclaim his valuable assets, showcasing the importance of collaboration and ingenuity in the world of cryptocurrency.
