TLS 1.3 is nearly here

TLS stands for "Transport Layer Security" and it's rather important. Why's that? Oh, I'm glad you asked. Here's me, yelling my password across the office to you: "PASSWORD!!!" You heard me loud and clear, right? But so did basically anyone else nearby. Now let's work in a little TLS love and...

Encryption 101: Decryptor’s thought process

In the previous parts 1, 2 and 3 of this series, we covered the basics of encryption, walked through a live example of a ransomware in detail, and talked about encryption weaknesses. In this part of the encryption 101 series, we will begin wrapping it up by going into detail on a ransomware with...

Amazon Linux AMI : python-crypto (ALAS-2018-977)

Weak ElGamal key parameters in PublicKey/ElGamal.py allow attackers to obtain sensitive information by reading ciphertext : lib/Crypto/PublicKey/ElGamal.py in PyCrypto through 2.6.1 generates weak ElGamal key parameters, which allows attackers to obtain sensitive information by reading ciphertext...

ARM mbed TLS integer overflow vulnerability

ARM mbed TLS is a product that provides secure communication and encryption capabilities for mbed products. An integer overflow vulnerability exists in ARM mbed TLS. Due to a failure in the sslparseclientpskidentity function, the affected software fails to properly perform boundary checks. An...

CVE-2018-0902

The Cryptography Next Generation CNG kernel-mode driver cng.sys in Windows 10 Gold, 1511, 1607, 1703, and 1709. Windows Server 2016 and Windows Server, version 1709 allows a security feature bypass vulnerability due to the way the kernel-mode driver validates and enforces impersonation levels, ak...

OpenJDK: insufficient strength of key agreement (JCE, 8185292)

It was discovered that the key agreement implementations in the JCE component of OpenJDK did not guarantee sufficient strength of used keys to adequately protect generated shared secret. This could make it easier to break data encryption by attacking key agreement rather than the encryption using...
