In March 2017, Microsoft (known for fixing vulnerabilities in their software products once a month on “Patch Tuesday”) recently addressed post-infection detection, investigation, and response with their Windows Defender Advanced Threat Protection [ATP]). Microsoft is a company that is continuing to evolve in product/services, and is now

In late 2016, enSilo researchers shared AtomBombing with the security world. More of a “proof of concept” than an actual exploit, AtomBombing took advantage of Microsoft Windows built-in atom tables that would allow specific API calls to inject code into the read-write memory space of a targeted process.
(NOTE: enSilo endpoint protection

Windows environment variables can be used to run commands and can also be used to bypass UAC, allowing an attacker with limited privileges to take complete control of the system. This code leverages a rather unusual scenario within Windows OS.
This is a continuation of our research as described in a previous post: Elastic Boundaries – Elevating

TL;DR: We show AtomBombing modifications to enable us to inject code into CFG-protected processes.

Our research team has uncovered new way to leverage mechanisms of the underlying Windows operating system in order to inject malicious code. (This research is one way enSilo ensures complete endpoint protection.) Threat actors can use this technique, which exists by design of the operating system, to bypass current security solutions that

TL;DR Here’s a new code injection technique, dubbed AtomBombing, which exploits Windows atom tables and Async Procedure Calls (APC). Currently, this technique goes undetected by common security solutions that focus on preventing infiltration.

Even though any process is provided with variables from its environment, they are often overlooked by users, developers and sometimes even the OS itself.

For over a year our enSilo researchers have been looking into hooking engines and injection methods used by different vendors. It all started back in 2015 when we noticed injection issue in AVG but this was only the tip of the iceberg. A few months after that we noticed similar issues in McAfee and Kaspersky Anti-Virus. At that point we decided

TL;DR: We found 6(!) different common security issues that stem from incorrect implementation of code hooking and injection techniques. These issues were found in more than 15 different products. The most impactful discovery was that three different hooking engines also suffer from these kind problems, including the most popular commercial
