How Researchers Cracked an 11-Year-Old Password for a $3 Million Crypto Wallet
“Ultimately, we were lucky because our parameters and time frame were correct. If any of them were wrong, we would have…continued to make assumptions/shots in the dark,” Grand said in an email to WIRED. “It would have taken much longer to pre-calculate all possible passwords.”
Grande and Bruno created a video to explain the technical details in more detail.
RoboForm, manufactured by US-based Siber Systems, was one of the first password managers on the market and currently has more than 6 million users around the world, according to a company report. In 2015, Siber appeared to fix the RoboForm password manager. In a quick look, Grand and Bruno were unable to find any sign that the pseudo-random number generator in the 2015 version used computer time, which makes them think they removed it to fix the flaw, although Grand says they would need to look into it. in more detail to be sure.
Siber Systems confirmed to WIRED that it fixed the issue with version 7.9.14 of RoboForm, released on June 10, 2015, but a spokesperson did not respond to questions about how it happened. On a change log on the company’s website it only mentions that Siber programmers made changes to “increase the randomness of the generated passwords”, but does not say how they did this. Siber spokesperson Simon Davis says “RoboForm 7 was discontinued in 2017.”
Grand says that without knowing how Siber fixed the problem, attackers will still be able to regenerate passwords generated by versions of RoboForm released before the fix in 2015. He’s also not sure whether current versions contain the problem.
“I’m still not sure I’d trust it without knowing how they’ve actually improved password generation in newer versions,” he says. “I’m not sure RoboForm knew how bad this particular weakness was.”
Customers can also still use passwords generated in previous versions of the program before the fix. It appears that Siber never notified customers when it released fixed version 7.9.14 in 2015 that they should generate new passwords for critical accounts or data. The company did not respond to a question about this.
If Siber didn’t inform customers, it would mean that anyone like Michael, who used RoboForm to generate passwords before 2015 — and still uses those passwords — could have vulnerable passwords that hackers could regenerate.
“We know that most people don’t change passwords unless asked,” says Grand. “Of the 935 passwords in my password manager (not RoboForm), 220 of them are from 2015 and earlier, and most of them are [for] sites I still use.”
Depending on what the company did to fix the problem in 2015, newer passwords could also be vulnerable.
Last November, Grand and Bruno deducted a percentage of bitcoins from Michael’s account for the work they did and then gave him the password to access the rest. Bitcoin was worth $38,000 per coin at the time. Michael waited until the value rose to $62,000 per coin and sold some of it. He now has 30 BTC, now worth $3 million, and is hoping the value will rise to $100,000 per coin.
Michael says he’s lucky he lost the password years ago because otherwise he would have sold bitcoin when it was worth $40,000 per coin and lost a greater fortune.
“The fact that I lost the password was a financially good thing.”

Bitcoin (BTC), Stocks Bleed as China’s Surprise Rate Cut Signals Panic, Treasury Yield Curve Steepens
Risk assets fell on Thursday as China’s second rate cut in a week raised concerns of instability in the world’s second-largest economy.
Bitcoin (BTC)the leading cryptocurrency by market cap, is down nearly 2% since midnight UTC to around $64,000 and ether (ETH) fell more than 5%, dragging the broader altcoin market lower. The CoinDesk 20 Index (CD20), a measure of the broader cryptocurrency market, lost 4.6% in 24 hours.
In equity markets, Germany’s DAX, France’s CAC and the euro zone’s Euro Stoxx 50 all fell more than 1.5%, and futures linked to the tech-heavy Nasdaq 100 were down slightly after the index’s 3% drop on Wednesday, according to the data source. Investing.com.
On Thursday morning, the People’s Bank of China (PBoC) announced a surprise, cut outside the schedule in its one-year medium-term lending rate to 2.3% from 2.5%, injecting 200 billion yuan ($27.5 billion) of liquidity into the market. That is the biggest reduction since 2020.
The movement, together with similar reductions in other lending rates earlier this week shows the urgency among policymakers to sustain growth after their recent third plenary offered little hope of a boost. Data released earlier this month showed China’s economy expanded 4.7% in the second quarter at an annualized pace, much weaker than the 5.1% estimated and slower than the 5.3% in the first quarter.
“Equity futures are flat after yesterday’s bloody session that shook sentiment across asset classes,” Ilan Solot, senior global strategist at Marex Solutions, said in a note shared with CoinDesk. “The PBoC’s decision to cut rates in a surprise move has only added to the sense of panic.” Marex Solutions, a division of global financial platform Marex, specializes in creating and distributing custom derivatives products and issuing structured products tied to cryptocurrencies.
Solot noted the continued “steepening of the US Treasury yield curve” as a threat to risk assets including cryptocurrencies, echoing CoinDesk Reports since the beginning of this month.
The yield curve steepens when the difference between longer-duration and shorter-duration bond yields widens. This month, the spread between 10-year and two-year Treasury yields widened by 20 basis points to -0.12 basis points (bps), mainly due to stickier 10-year yields.
“For me, the biggest concern is the shape of the US yield curve, which continues to steepen. The 2- and 10-year curve is not only -12 bps inverted, compared to -50 bps last month. The recent moves have been led by the rise in back-end [10y] yields and lower-than-expected decline in yields,” Solot said.
That’s a sign that markets expect the Fed to cut rates but see tighter inflation and expansionary fiscal policy as growing risks, Solot said.
