The official app is due to be rolled out for testing in the province of Ontario as soon as next month.

Visibility and Threat Detection in a Remote Working World

securityintelligence.com/posts/visibility-threat-detection-remote-work/ At the outset of the COVID-19 pandemic, when governments around the world put stay-at-home orders in place, it was hard to imagine the state of work would permanently change.

Although they were intended as a simple feature to make Windows a bit more user-friendly, over the years, a significant number[1] of vulnerabilities were identified in handling of LNKs. Many of these vulnerabilities lead to remote code execution and one (CVE-2010-2568) was even used in creation of the Stuxnet worm.

Magnitude exploit kit evolution

securelist.com/magnitude-exploit-kit-evolution/97436/ Exploit kits are not as widespread as they used to be. In the past, they relied on the use of already patched vulnerabilities. Newer and more secure web browsers with automatic updates simply do not allow known vulnerabilities to be exploited. It was very different back in the heyday of Adobe Flash because its just a plugin for a web browser, meaning that even if the user has an up-to-date browser, theres a non-zero chance that Adobe Flash may still be vulnerable to 1-day exploits. Now that Adobe Flash is about to reach its end-of-life date at the end of this year, it is disabled by default in all web browser and has pretty much been replaced with open standards such as HTML5, WebGL, WebAssembly.
