Researchers discovered six new vulnerabilities in D-Link wireless cloud routers running their latest firmware. The reported vulnerabilities were found in the DIR-865L model of D-Link routers, which is meant for home network use. There are also likelihood that some of these vulnerabilities are present in newer models of the router because of the similiarities in codebase.
VMware Fusion, VMRC, and Horizon Client contain a local privilege escalation vulnerability due to a Time-of-check Time-of-use (TOC/TOU) issue in the service opener. Furthermore, another local privilege escalation was discovered, which allows the application to blindly executes files from an untrusted location. Both vulnerabilities result in arbitrary code execution as root.

In addition, the APT is responsible for a campaign against an unnamed African ministry of foreign affairs.
Rootkits are one of the most damaging types of malware. They are very difficult to detect & remove and provide the Threat Actors almost complete access to the target computer. A hacker who installs a rootkit into a computer can access & steal data, delete or corrupt files, spy on all system activities, modify programs, etc. Since rootkits remain constantly hidden and avoid detection, most commercially available anti-virus software is ineffective against them.
A security researcher discovered and reported a privilege escalation vulnerability in the Windows Installer software component, which was later fixed by Microsoft. The flaw not only allows for the bypass of Microsoft's previous fix, but it also allows for local privilege escalation via the newly discovered zero-day bug.

Emotet has evolved since its first appearance in 2014, causing significant damage in its wake. From a Trojan that targeted banking apps to one of the first Malware-as-a-Service (MaaS) botnets that infected a large number of devices and then sold access to third parties. It is currently stealing credit card information while evading security measures. The "improved" version of Emotet is engaging in "disturbing" behavior, effectively collecting and using stolen credentials, which are then weaponized to further distribute the Emotet binaries.
An Android malware that is both an adware and information-stealer has been downloaded over two million times on the Google Play Store.
