No, it definitely won't. I personally spent several years building SHA-256 as a Boolean circuit and then using all the most sophisticated techniques known to math and cryptography to try to invert that function (to execute a preimage attack). I know the math of SHA-256 more deeply than most people on this planet. It's exceptionally well-defined as a trapdoor function, and inverting it is most certainly NP complete. I also spent over 30 years trying to prove that P = NP, and threw my entire 30 years of knowledge of this problem at frontier LLMs to try to crack it. What they ended up doing was to thoroughly and convincingly refute every single line of reasoning and "clever" trick I came up with over those decades, which has now left me believing for the first time that actually P≠NP.

Saying there’s no reason to buy Bitcoin because anyone can create a cryptocurrency is like saying there’s no reason to learn English because anyone can invent a language.

INVESTIGATION UPDATE Many of you have asked how personal information ended up in the phishing emails, particularly those who ordered from us years ago. Here is what we have found so far. Phishing emails: We have identified more than 23,000 phishing email attempts across our email systems, including 19,057 messages delivered through Mailgun and 1,503 messages sent through Google Workspace. Some addresses received multiple messages, and some attempts failed or were stopped before delivery. These numbers do not tell us how many people had personal information exposed. We are still determining that number and will share it once we can confirm it. Older orders and abandoned carts (WooCommerce): Before moving to Shopify in May of this year, our store ran on WooCommerce. We had configured automatic redaction of customer details 60 days after shipping. When we viewed those orders in our store admin, the customer details were no longer visible and the orders showed as redacted. During past database migrations, orders were copied into a new set of tables, but copies remained in the old tables. The redaction process updated the newer tables, which were also what our store admin displayed. Orders therefore appeared redacted even though older copies still contained personal information. We also found personal information in other order and refund records, as well as abandoned carts. This included shipping details entered by someone who never completed a purchase. We are still checking the historical settings and redaction process to understand why these records retained data. Those older records were held in systems the attackers were able to reach. We relied on the redaction shown in our admin dashboard, and we now know that was insufficient to verify that the underlying data had been removed. Whatever the shortcomings in the tools we used, protecting your information was still our full responsibility. We plan to share our findings with WooCommerce and the relevant plugin developers. When an order is marked as redacted, its personal information should not remain in another table in the same database. For other WooCommerce store owners: do not rely solely on what your admin dashboard shows when personal data is redacted. Have your developer or agent check the entire database for information left behind, including legacy tables, refund records, and abandoned carts. This is especially important if you have used WooCommerce for years or have been through database migrations. Recent orders (Shopify): Customer details from orders placed on our Shopify store since May may also have been exposed. We are still investigating the extent of any unauthorized access. These orders had not yet been manually redacted. We updated our privacy policy when we moved to Shopify and were building a tool to automate redaction, but automatic deletion was not yet active. Other possible sources: We have received reports of phishing emails containing personal details that customers say they never shared with us. We are investigating whether the attackers combined information from our systems with data obtained elsewhere, but we have not confirmed a connection to breaches at other companies. Historical support records are also part of our investigation. What we have done: We have revoked affected email credentials, cleared queued phishing messages, and taken affected legacy services offline while preserving evidence. Our investigation into the full extent of the compromise is continuing. We have found no evidence that this incident compromised Passport devices or the private keys they hold. The phishing emails are designed to trick you into revealing your recovery phrase, and including your correct personal information makes them more convincing. Never enter your recovery phrase into a website or share it with anyone, including someone claiming to be Foundation. We will continue sharing confirmed findings and publish our full report when the investigation is complete.

ANNOUNCEMENT: SPAM EMAILS HAVE BEEN SENT THAT APPEAR TO HAVE COME FROM OFFICIAL FOUNDATION DOMAINS. We have traced this back to one or more compromised API keys on Cloudflare, and have already revoked all API keys. The malicious domain in the spam email has been taken down. Funds stored on Passport are safe and Passport hardware is not compromised. We are working nonstop to discover exactly what happened and will put out a report ASAP.

Nothing like a good manufactured scare to dump the price. Seems to happen every so many months.

Incident Update - Oct 13th, 2026 Ledger is asking resellers and distributors in Southeast Asia and Hong Kong to suspend sales of Ledger devices while the investigation is ongoing. This includes taking products off the shelves. Specifically the countries are: Indonesia, Singapore, Thailand, Philippines, Vietnam, Malaysia, and Hong Kong. To be clear, as the investigation continues, the only confirmed incidents remain contained to Southeast Asia. We have not verified a drain linked to a device bought elsewhere. The investigation is ongoing to determine who tampered with these devices and where in the distribution chain it happened. The Ledger Donjon will analyze the devices it receives, and Ledger Customer Support will provide guidance to users who reach out through our official channel: support.ledger.com. We understand this is concerning, and will continue to provide updates from the Ledger Donjon as the investigation progresses. Stay vigilant. We have no indication that Ledger's infrastructure, systems or services or direct sales channel have been compromised.

Update from Ledger Donjon on the CryptoBilis investigation 🔽 @DonjonLedger is investigating Ledger signers sold by CryptoBilis, a reseller in Southeast Asia, that contained an unauthorized hardware implant. Ledger confirmed this on October 10th for one affected user's signer. All confirmed fund losses tied to the incident disclosed on October 9th involve signers sold through CryptoBilis. We have not verified a drain linked to a signer bought elsewhere. CryptoBilis has confirmed it stopped selling Ledger signers while the investigation continues. Based on the Donjon's analysis of the attack, the implant sits inside the enclosure and reads the data shown on the screen. During setup, the signer displays the 24-word recovery phrase. When the implant detects these screens, its microcontroller decodes the words and transmits them over LTE using a provisioned eSIM. The implant is a separate component. It does not modify the Secure Element or the Ledger operating system, and it does not alter transactions or signatures. The Donjon will analyze the signers it receives and will share more as the investigation continues. We have not confirmed the total number of affected users or the total value lost. Figures circulating online come from third parties and Ledger has not fully verified them. If your funds were drained and you have not contacted us, please do so through Ledger Support so we can include your case. We are also reviewing reports of implants in other signers and locations. We will continue to share information as the investigation progresses. Rest assured the Ledger team is going above and beyond to leave no stone unturned to investigate this situation to the strongest possible outcome. If you bought a Ledger signer from CryptoBilis and have not set it up, do not set it up and contact Ledger Support. If you have set it up, transfer your assets promptly to a new signer with a new recovery phrase. Do not enter or restore any recovery phrase on a signer bought from CryptoBilis. Never enter your recovery phrase into a website, app or form. If you lost funds or hold a tampered signer, contact Ledger Support at support.ledger.com and file a report with local law enforcement. Do not send the signer to anyone before speaking with Ledger Support or local law enforcement. If you lost funds, coordinate with law enforcement before opening the signer. Researchers and others with relevant information can write to [email protected]. If you did not buy from CryptoBilis and want to inspect the inside of your signer, the guide is at support.ledger.com/article/4…. Use caution and make sure your recovery phrase is backed up first, because opening a signer can damage it. Ledger will never call you, message you directly, or ask for your 24-word recovery phrase. We will update this post when we verify new information.

Following recent supply-chain incidents, we decided to reduce the number of resellers so we can more effectively check those we work with. Let us be very clear: there is not a single piece of evidence that Trezor devices have been compromised. This is a preventive step, taken out of an abundance of caution. We also want to thank everyone involved for the cooperation, and for the years of work putting Trezor in people’s hands.
To the resellers who helped build Trezor: thank you, and I’m sorry 💔

In 1979, a talk show host looked at one of the most influential economists alive and told him, on live television, that capitalism ran on greed. Milton Friedman had won the Nobel Prize in Economics three years earlier, in 1976, for his work on monetary theory and consumption analysis. Phil Donahue, host of the highest-rated daytime talk show in America, asked him directly whether the concentration of power and profit under capitalism had ever given him a moment of doubt. Friedman didn't pause before answering. "Well, first of all, tell me, is there some society you know that doesn't run on greed? You think Russia doesn't run on greed? You think China doesn't run on greed?" He kept going, arguing that only capitalist societies built on voluntary exchange had ever lifted large numbers of people out of poverty, while every attempt to replace self-interest with central planning had made things worse. Donahue tried one more angle, asking who would organize a fairer society if not government. Friedman's answer to that question is still being clipped and argued over online more than four decades later. Their exchange lasted less than two minutes inside a much longer interview about the Great Depression, auto bailouts, and price controls, and it's become one of the most replayed moments in the history of televised economics. Was Friedman right that every system runs on self-interest whether we admit it or not, or did he dodge the real question about inequality? Say which side you land on in the comments, then watch the full exchange below.
