Side Channel Attack

libgcrypt.so is vulnerable to side-channel attack. The vulnerability exists as the library fails to perform ciphertext blinding for the Elgamal decryption, allowing a local attacker to compromise the server's private key through a crafted ciphertext and analyzing the fluctuations in the...

CVE-2014-3591

Libgcrypt before 1.6.3 and GnuPG before 1.4.19 does not implement ciphertext blinding for Elgamal decryption, which allows physically proximate attackers to obtain the server's private key by determining factors using crafted ciphertext and the fluctuations in the electromagnetic field during...

Side-Channel PoC Attack Lifts Private RSA Keys from Mobile Phones

Researchers have developed a proof-of-concept side-channel attack that allows them to pull encryption keys from a single decryption for a modern version of OpenSSL. The attack impacts mobile devices — without physical access to the handsets. A group of researchers at Georgia Tech were able to...

Side-Channel Attack

libgcrypt.so is vulnerable to side-channel attacks. The elliptic-point curve multiplication during decryption is not properly performed, which allows attackers within close proximity to extract the secret decryption key within seconds by measuring electromagnetic emanations...

Hackers Can Now Steal Data Even From Faraday Cage Air-Gapped Computers

A team of security researchers—which majorly focuses on finding clever ways to get into air-gapped computers by exploiting little-noticed emissions of a computer's components like light, sound and heat—have published another research showcasing that they can steal data not only from an air gap...

How to Leak Data From Air Gapped Computers With USB Devices

Researchers at Ben-Gurion University of Negev have found a way to take a run-of-the-mill USB device and use it to leak data from an air-gapped computers via RF signals. Academics with the school’s Cyber Security Research Labs division claim they’ve come up with software, dubbed USBee, that can...

CVE-2015-7511

Libgcrypt before 1.6.5 does not properly perform elliptic-point curve multiplication during decryption, which makes it easier for physically proximate attackers to extract ECDH keys by measuring electromagnetic emanations...

libgcrypt: secret key extraction

A vulnerability was found in a way the ECDH encryption algorithm decrypts data. An attacker with a specialized setup can extract the secret decryption key from a target located in an adjacent room within seconds. This is done by measuring the target's electromagnetic emanations...

How-to — Stealing Decryption Key from Air-Gapped Computer in Another Room

Air-gapped computers that are believed to be the most secure computers on the planet have become a regular target for researchers in recent years. Air-gap computers are one that are isolated from the Internet or any other computers that are connected to the Internet or external network, so hacker...

Domain Creep? Maybe Not.

I just read a very interesting article by Sydney Freedberg titled DoD CIO Says Spectrum May Become Warfighting Domain. That basically summarizes what you need to know, but here's a bit more from the article: Pentagon officials are drafting new policy that would officially recognize the...

Hacking Air-Gapped Computer With A Simple Cell Phone

Wanna Hack an extremely secure Computer? You do not need sophisticated techniques or equipment to do so. To hack an Air-Gapped computer – All you need is a cell phone; even old-fashioned, dumb phones from the past decade will work. Yes, Hacking Air-Gapped Computers is possible using a basic low-e...

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...
