New Attack Lets Hackers Decrypt VoLTE Encryption to Spy on Phone Calls

A team of academic researchers—who previously made the headlines earlier this year for uncovering severe security issues in the 4G LTE and 5G networks—today presented a new attack called 'ReVoLTE ,' that could let remote attackers break the encryption used by VoLTE voice calls and spy on targeted...

ReVoLTE Attack Allows Hackers to Listen in on Mobile Calls

Researchers have discovered an attack on the Voice over LTE VoLTE mobile communications protocol that can break its encryption and allow attackers to listen in on phone calls. Dubbed ReVoLTE, the attack — detailed by a group of academic researchers from Ruhr University Bochum and New York...

golang.org/x/crypto: Keystream loop in amd64 assembly when overflowing 32-bit counter

An issue was discovered in the supplementary Go cryptography library, golang.org/x/crypto, before v0.0.0-20190320223903-b7391e95e576. A flaw was found in the amd64 implementation of the golang.org/x/crypto/salsa20 and golang.org/x/crypto/salsa20/salsa packages. If more than 256 GiB of keystream i...

RUSTSEC-2019-0029 ChaCha20 counter overflow can expose repetitions in the keystream

The ChaCha20 stream cipher can produce a maximum of 2^32 blocks 256GB before the 32-bit counter overflows. Releases of the chacha20 crate prior to v0.2.3 allow generating keystreams larger than this, including seeking past the limit. When this occurs, the keystream is duplicated, with failure mod...

Wrong And Predictable Encryption

github.com/golang/crypto is vulnerable to predictable encryption. In the keystream generation of more than 256 GiB in the amd64 implementation of golang.org/x/crypto/salsa20 and golang.org/x/crypto/salsa20/salsa, it can first generate incorrect output and finally cycling back to the previously...

CVE-2019-11840

CVE-2019-11840 affects golang.org/x/crypto (amd64 salsa20 and salsa20/salsa). If keystream surpasses 256 GiB or the counter grows beyond 32 bits, output becomes incorrect and then repeats earlier keystream, causing potential confidentiality loss in encryption/CSPRNG. The connected Debian advisory...

Attack Exploits Weakness in RC4 Cipher to Decrypt User Sessions

It’s been more than 25 years since Ron Rivest invented his RC4 stream cipher, and after all that time it’s still being used widely, which is something of an achievement in the crypto world. However, for more than 15 years researchers have known about a weakness in RC4 that could enable an attacke...
