This week on the podcast, we discuss a research post by SquareX that invents a new way to impersonate any extension installed on a victim's web browser. Before that, we cover the latest supply chain attack attempts from Lazarus, as well as a malvertising campaign that managed to infect 1 million endpoints. The 443 Security Simplified is a weekly podcast that gets inside the minds of leading white-hat hackers and security researchers, covering the latest cybersecurity headlines and trends.
