Factorization Flaw in TPM Chips Makes Attacks on RSA Private Keys Feasible

A flawed Infineon Technology chipset used on PC motherboards to securely store passwords, certificates and encryption keys risks undermining the security of government and corporate computers protected by RSA encryption keys. In a nutshell, the bug makes it possible for an attacker to calculate a...

CVE-2017-11136

An issue was discovered in heinekingmedia StashCat through 1.7.5 for Android, through 0.0.80w for Web, and through 0.0.86 for Desktop. It uses RSA to exchange a secret for symmetric encryption of messages. However, the private RSA key is not only stored on the client but transmitted to the backen...

U.S. Dept Of Defense: Multiple cryptographic vulnerabilities in login page on ███████

Summary: I realize that this report's title may not make sense yet. In one sentence: users logging in to the ███████ Server REST API Login page can have their passwords stolen by an attacker on the same LAN or WiFi as the victim trying to log in. Description: To save the reader any confusion, I'l...

The developer’s code set vulnerability in Cavium’s SDK, allowing attackers to obtain encrypted RSA keys.

The vulnerability of the RSA-CRT implementation in the developer’s toolkit for devices based on Cavium processors is related to the lack of protection for sensitive data. Exploiting this vulnerability allows a malicious actor to obtain encrypted RSA keys by launching attacks through external...

Spora Ransomware Offers Unique Payment Options

Researchers are keeping close tabs on a new ransomware strain called Spora that offers victims unique payment options and comes with top-notch encryption. Spora was spotted last week by ransomware experts at BleepingComputer, who said after Spora encrypts files on your computer, it offers four...

SSL/TLS: Cross-protocol attack on TLS using SSLv2 (DROWN)

A padding oracle flaw was found in the Secure Sockets Layer version 2.0 SSLv2 protocol. An attacker could potentially use this flaw to decrypt RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol version, allowing them to decrypt such connections. This cross-protocol attack ...

PITA Side-Channel Crypto Key Attack

It’s unlikely that anyone envisioned the evolution of cryptographic key thievery to include leavened flatbread, but that’s where we’ve arrived. Researchers from Tel Aviv University in Israel are expected in September to present a paper at the Workshop on Cryptographic Hardware and Embedded System...

U.S. Oil, Gas Targeted by Espionage Malware Campaign

American gas and oil companies have been targeted by a hacking group with ties to the Russian Federation for close to 18 months, a new research report indicates. The attackers have leveraged watering hole attacks to infect users inside the critical infrastructure organizations to spread a remote...
