Apple iOS 0-days exploited in the wild

Two iOS zero-day vulnerabilities, which have existed at least since iOS 6, were exploited in the wild. Both of them affect Apple's iPhones and iPads and are triggered by a specially crafted email sent in the context of iOS MobileMail on iOS 12 or maild on iOS 13. The vulnerabilities enable remote code execution and infection of a device by sending memory consuming emails. There is no final patch yet except for iOS 13.4.5 beta; thus, it is strongly recommended to avoid using the Mail application on iPhones and iPads. 

Hupigon taught new tricks

Hupigon is a remote access Trojan that has been operating since 2006. Recently, it has been repurposed to target faculty and students at United States colleges and universities.

Microsoft Teams recent fix

Google Chrome against Windows 10

Researchers have revealed that some of the features of Google Chrome for Windows could become insecure due to the changes in the Windows OS itself. The Chromium sandbox development team relies on the security of the operating system and its updates. A bug in security enforcement mechanisms of Windows can break the Chromium sandbox. The recent Microsoft fix of the CVE-2020-0981 vulnerability helped to mitigate the security flaws for Chromium-based browsers with Windows 10 1903 update. Still, there is no guarantee that the next OS update will not affect the security of the Chromium-based browsers.
