Fired by algorithm: The future’s here and it’s a robot wearing a white collar

Black Mirror meets 1984. Imagine that your employer uses a bot to keep track of your “production level.” And when this bot finds that you are an under-performer it fires off a contract-termination mail. Does this sound like the world you live in? Unfortunately, for some people it is. The case...

The vulnerability of the ntpkeygen component in the NTPsec network time protocol allows a attacker to perform a type of “man-in-the-middle” attack.

The vulnerability of the ntpkeygen component in the NTPsec network time protocol implementation is related to the use of cryptographic algorithms that contain vulnerabilities. Exploiting this vulnerability could allow a malicious actor to perform a “man-in-the-middle” attack between NTP clients a...

CVE-2021-20566

CVE-2021-20566 concerns IBM Resilient OnPrem (IBM Security SOAR) where TLS1.2 ciphers not enabled for Perfect Forward Secrecy allow potential decryption of sensitive data if an attacker records traffic. The IBM security bulletin notes the vulnerability stems from weaker cryptographic algorithms; ...

nettle: Out of bounds memory access in signature verification

A flaw was found in Nettle, where several Nettle signature verification functions GOST DSA, EDDSA & ECDSA result in the Elliptic Curve Cryptography point ECC multiply function being called with out-of-range scalers, possibly resulting in incorrect results. This flaw allows an attacker to force an...
