all your crypto are belong to us (private key from public key only)

Oct 17 03:05 [raw]

I don't know why this is hidden in the news. 76$ on amazone buys your private key from your public one, 1024 key lenght. 2048keys take a bit longer. Imaging sigining git repo for ... I don't know bitmessage or, some other code you run. What would they pay to infect everyones PC. How many code signatures are hacked? Does this impact GPG? Yubi? Is this fake? A crippling flaw in a widely used code library has fatally undermined the security of millions of encryption keys used in some of the highest-stakes settings, including national identity cards, software- and application-signing, and trusted platform modules protecting government and corporate computers. The weakness allows attackers to calculate the private portion of any vulnerable key using nothing more than the corresponding public portion. Hackers can then use the private key to impersonate key owners, decrypt sensitive data, sneak malicious code into digitally signed software, and bypass protections that prevent accessing or tampering with stolen PCs. The five-year-old flaw is also troubling because it's located in code that complies with two internationally recognized security certification standards that are binding on many governments, contractors, and companies around the world. The code library was developed by German chipmaker Infineon and has been generating weak keys since 2012 at the latest. The flaw is the one Estonia's government obliquely referred to last month when it warned that 750,000 digital IDs issued since 2014 were vulnerable to attack. Estonian officials said they were closing the ID card public key database to prevent abuse. On Monday, officials posted this update. Last week, Microsoft, Google, and Infineon all warned how the weakness can impair the protections built into TPM products that ironically enough are designed to give an additional measure of security to high-targeted individuals and organizations.

It only effects keys generated from these specific hardware devices (TPMs by Infineon). So GPG is safe. And most open source repos are probably signed using software generated keys. The smart cards have a problem because they've got the TPM inside, I guess.

> Does this impact GPG? Yubi? The description says it affects private keys generated by some hardware devices using Infineon chips. It doesn't affect X86 CPUs, so software GPG seems safe. I used the testing tool to test my PGP public key that's on my Yubikey as well as the code signing DER certificate that's on a different smart card, and it said both are safe (they probably don't use an Infineon chip). > Is this fake? Probably not. Peter Surda Bitmessage core developer

It depends on the firmware version of the Yubikey. If you generate your RSA key on your local system, you are safe.

Had one yubikey with vulnerable firmware, it was very easy to get a replacement key, though, through the yubico website. Not using the onboard RSA generation, though.

Infineon is part of Siemens AG. Siemens AG is part of German intelligence services. The same Siemens AG from "swiss" Crypto AG scandal. All was needed is to read carefully about Infineon's management structure. Then it will be obvious they are BND/NSA puppet. Start thinking, people. It doesn't hurt.
