This article discusses the misuse of X.509 certificates and keys in the SolarWinds attack and how Cryptomathic CKMS and CSG could help protect against such attacks.

Since the announcement of the SolarWinds supply chain attack, intensive analysis has been done by Crowdstrike, FireEye (with additional details), Microsoft, Symantec, SolarWinds, and many others, to understand the attack’s workings both within SolarWinds and in the targeted networks. Here we focus on the code signing procedures, which seemingly failed at SolarWinds but likely could have mitigated the risk of the attack if they had been implemented and enforced to a higher standard.

The business world today is built on the pervasive use of cryptography, to authenticate people and processes, to secure communications, and to protect sensitive data.

The first practical chosen-prefix collision attack on SHA-1 was announced in January 2020 by researchers Gaëtan Leurent and Thomas Peyrin: “SHA-1 is a Shambles”.  

This article discusses recent warnings that a chosen-prefix collision attack on SHA-1 is now practical and cost-effective for attackers.

This article discusses how tokenization may reduce false declines with credit card transactions that could negatively impact merchants.

The EMV consortium released several standards detailing how “network” tokenization should be handled. There is now a general consensus within the consortium that tokenization could be the next major task for EMV payments.

Tokenization is a generalized concept of a cryptographic hash. It means representing something by a symbol (‘token’).

EMV is short for EUROPAY-VISA-MASTERCARD. This term is used to refer to standards that have been designed to improve the security of credit and debit card transactions by using chip technology for payment cards.
