In a recent blog post by Microsoft, a new Zero-Day vulnerability (CVE-2022-30190) was discussed. This vulnerability affects Microsoft Support Diagnostic Tool (MSDT), and the blog post provides some guidance on mitigating the impact of this vulnerability.
The post mentions that a Remote Code Execution (RCE) vulnerability present in MSDT allows the attackers to execute arbitrary code by exploiting it.…
Fortinet’s FortiGuard Labs captured a phishing campaign that delivers three fileless malware onto a victim’s device. Once executed, they are able to control and steal sensitive information from that device to perform other actions according to the control commands from their server.
In Part I of this analysis, I introduced how these three fileless malware are delivered to the victim’s device via a phishing campaign, and what mechanism it uses to load, deploy, and execute these fileless malware in the target process.…

We all know vulnerabilities have a lifecycle. First, they start as closely held secrets, hopefully known to the company producing the vulnerable software. After becoming publically known, there is often a “mad dash” to a public exploit. During this phase, security companies often show their skills by hinting at privately developed exploits first until the exploit is publically known.…
