Zk-SNARK, which stands for zero-knowledge succinct non-interactive argument or knowledge, is the most popular zero-knowledge protocol.
This a space of increasing importance, as zero knowledge systems are an area of active development that stand to disrupt how authentication works. While the math is intense, the overall ideas are not hard to understand.
What is zero knowledge?
Zero knowledge is the attempt to use the smallest amount of information possible when verifying a statement. It works to devise proofs that avoid transfer of extra data.
Ground zero for this field is the paper Knowledge Complexity of Interactive Proof Systems, which appeared in a few editions during the 1980’s. As the name implies, the paper undertakes to get an understanding of how knowledge behaves in proving statements between interacting systems.
The Institute for Security and Technology (IST) recently released a “Blueprint for Ransomware Defense.” The guide includes recommendations of defensive actions for small- and medium-sized businesses (SMBs) to protect against and respond to ransomware and other common cyberattacks. It focuses on the identify, protect, respond, and recover format that aligns with the National Institute of Standards and Technology (NIST) Cybersecurity Framework. IST’s guidelines do not include one item from the NIST framework: the detect function. The authors recommends that SMBs should work with a cybersecurity services provider for that function.
Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could allow for arbitrary code execution. Google Chrome is a web browser used to access the Internet.
Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights

A flaw was found in Red Hat AMQ Broker in a way that a XEE attack can be done via Broker’s configuration files, leading to denial of service and information disclosure.
In Moodle before 3.9.1, 3.8.4, 3.7.7 and 3.5.13, yui_combo needed to limit the amount of files it can load to help mitigate the risk of denial of service.
