Bleichenbacher, the name that always chills cryptographers' blood If you're an F5 BIG-IP sysadmin, get patching: there's a bug in the company's RSA implementation that can give an attacker access to encrypted messages.…
In early October, a story was published by the Wall Street Journal alleging Kaspersky Lab software was used to siphon classified data from an NSA employeersquo;s home computer system.

To assist any independent investigators and all the people who have been asking us questions whether those allegations were true, we decided to conduct an internal investigation to attempt to answer a few questions we had related to the article and some others
The P1735 IEEE standard describes methods for encrypting electronic-design intellectual property(IP),as well as the management of access rights for such IP.

The methods are flawed and,in the most egregious cases,enable attack vectors that allow recovery of the entire underlying plaintext IP.
Implementations of IEEE P1735 may be weak to cryptographic attacks that allow an attacker to obtain plaintext intellectual property without the key,among other impacts.
Savitech provides USB audio drivers for a number of specialized audio products.
Some versions of the Savitech driver package silently install a root CA certificate into the Windows trusted root certificate store.

Bad Rabbit ransomware

On October 24th we observed notifications of mass attacks with ransomware called Bad Rabbit.
It has been targeting organizations and consumers, mostly in Russia but there have also been reports of victims in Ukraine.
Here's what to do if you have an affected badge Some Gemalto smartcards can be potentially cloned and used by highly skilled crooks due to a cryptography blunder dubbed ROCA.…
KRACK, ROCO, exposed SSH keys and the European Commission's loosey-goosey stance on backdoors have made it a rough week for cryptography. Here's your wrap-up on the best of the worst.
A new security flaw has placed the security of RSA encryption in jeopardy.
All modern WiFi access points and devices that have implemented the protocol vulnerable to attacks that allow decryption, traffic hijacking other attacks.
Second, unrelated crypto vulnerability also found in RSA code library in TPM chips.
About a third of all crypto modules globally generate weak, crackable RSA pairs RSA keys produced by smartcards, security tokens, laptops, and other devices using cryptography chips made by Infineon Technologies are weak and crackable – and should be r...
The Infineon RSA library version 1.02.013 does not properly generate RSA key pairs,which may allow an attacker to recover the RSA private key corresponding to an RSA public key generated by this library.

This vulnerability is often cited asROCAin the media.
A flawed Infineon Technology chipset left HP, Lenovo and Microsoft devices open to what is called a 'practical factorization attack,' in which an attacker computes the private part of an RSA key.
