SHA1 vulnerable
As computers evolve its becoming aier to break into aglorithms.It appears that upgrading the algorithm to SHA2 and SHA3 be the rigt way to go ahed.As quantum computers evolve it is just a  matter of time when algorithms like SHA2 and SHA 3 can also be broken.

Improving Enterprise Cybersecurity With XDR
Enterprises are looking at eXtended Detection and Response technologies to improve their abilities to detect, and respond to, threats. While endpoint detection and response is not new to enterprise security, organizations have to improve network visibility, expand data collection and expand threat hunting capabilites if they want their XDR deployments to succeed. This issue of Tech Insights also includes: a market overview for XDR from Omdia, questions to ask before deploying XDR, and an XDR primer.

CVE-2022-34750
PUBLISHED: 2022-06-28
An issue was discovered in MediaWiki through 1.38.1. The lemma length of a Wikibase lexeme is currently capped at a thousand characters. Unfortunately, this length is not validated, allowing much larger lexemes to be created, which introduces various denial-of-service attack vectors within the Wikib...
