In this series focusing on Active Directory attacks, we’re running through four different scenarios based on real penetration testing engagements that demonstrate the variety of techniques and tactics that can be used to compromise
In part 13, we analyzed and adapted the RESOLVER for 64 bits. In this part, we’ll discuss how to analyze the difficulty of creating a rop depending on the scenario.
Active Directory is an essential application within an organization, facilitating and centralizing network management through domain, user, and object creation, as well as authentication and authorization of users. Active Directory also serves as a database, storing usernames, passwords, permissions, and more. Active Directory is a perfect example of a technological double-edged sword. While such a centralized application can streamline IT operations, it does also make for an irresistible target for attackers.
Penetration testing is more than a bunch of ex-hackers in hoodies attempting to break into an organization that hired them. It is a carefully planned and organized engagement that probes and tests a defined piece of an organization's IT infrastructure for potential flaws. Without good intelligence to work from, testers cannot efficiently conduct their attacks, leaving potentially unidentified gaps in an organization’s defense.
When we think about EDR or AV evasion, one of the most widespread methods adopted by offensive teams is the use of system calls (syscalls) to carry out specific actions. This technique is so common and effective simply because most AVs/EDR have userland hooks to track and intercept requests userland processes make. However, we found that a key userland API, CreateProcess, is still extensively used even in offensive tools to create processes.
I wanted to write this article to demonstrate the analysis I did while developing the Core Impact exploit “Windows Network File System Remote” that abuses the CVE-2022-30136 vulnerability.
Fortra’s Elite Offensive Security Bundle is comprised of three distinct enterprise-grade tools: Fortra VM scans networks for vulnerabilities, Core Impact pen tests exploitation
Cyber criminals focus on the easiest targets, which often are federal agencies. A recent White House Executive Order on cybersecurity puts renewed focus squarely on securing federal network infrastructure. The order promotes, among other things, modernizing federal cybersecurity, improving detection of vulnerabilities and incidents, and moving toward a Zero Trust security model.
