NOTABLE RECENT SECURITY ISSUES

Title: New, custom dropper delivers variety of information-stealing malware
Description: A wave of adversaries which are dropping well-known information-stealer like Agent Tesla, Loki-bot and others since at least January 2019 using custom droppers. These droppers inject the final malware into common processes on the victim machine. Once infected, the malware can steal information from many popular pieces of software, including the Google Chrome, Safari and Firefox web browsers. The injection techniques are well-known and have been used for many years, but with the adversaries customizing them, traditional anti-virus systems are having a hard time detecting the embedded malware.

Title: Denial-of-service vulnerability in some Intel graphics drivers
Description: Intel’s IGC64.dll graphics driver contains a denial-of-service vulnerability. An attacker could exploit this bug by supplying a malformed pixel shader if the graphics driver is operating inside a VMware guest operating system. This type of attack can be triggered from VMware guest usermode to cause a denial-of-service attack due to an out-of-bounds read in the driver.
