K20281756: Libgcrypt vulnerability CVE-2017-7526
Security Advisory Description libgcrypt before version 1.7.8 is vulnerable to a cache side-channel attack resulting into a complete break of RSA-1024 while using the left-to-right method for computing the sliding-window expansion. The same attack is believed to work on RSA-2048 with moderately mo...
Breaking RSA with a Quantum Computer
A group of Chinese researchers have just published a paper claiming that they can--although they have not yet done so--break 2048-bit RSA. This is something to take seriously. It might not be correct, but its not obviously wrong. We have long known from Shors algorithm that factoring with a quant...
CVE-2021-42114
Modern DRAM devices PC-DDR4, LPDDR4X are affected by a vulnerability in their internal Target Row Refresh TRR mitigation against Rowhammer attacks. Novel non-uniform Rowhammer access patterns, consisting of aggressors with different frequencies, phases, and amplitudes allow triggering bit flips o...

Ryuk Hauls in $3.7M in 'Earnings,' Adds TrickBot to the Attack Mix
The Ryuk ransomware has raked in $3.7 million in bitcoin payments since it first appeared last August, researchers say – and has emerged as the calling card for a crime organization called Grim Spider a.k.a. MixMaster. It turns out that Grim Spider could share a link with other crime syndicates,...
CVE-2017-7526
libgcrypt before version 1.7.8 is vulnerable to a cache side-channel attack resulting into a complete break of RSA-1024 while using the left-to-right method for computing the sliding-window expansion. The same attack is believed to work on RSA-2048 with moderately more computation. This...
CVE-2017-7526
GnuPG/libgcrypt: CVE-2017-7526 affects libgcrypt before 1.7.8, allowing a cache-side-channel attack that can fully recover RSA-1024 private keys (and likely RSA-2048 with more effort) when the attacker can run code on the same hardware. Connected sources confirm the vulnerability exists in libgcr...

Libgcrypt Attack Allowed Recovery of RSA-1024 Keys
The cryptographic library Libgcrypt is vulnerable to a local side-channel attack; something researchers warn could allow full key recovery for RSA-1024. The vulnerability CVE-2017-7526 is tied to the fact that Libgcrypt, which is based on code from GnuPG, uses left to right sliding windows...
