5 Most Common Malware Techniques in 2024

Nov 07, 2024 Malware Analysis / Windows Security
Tactics, techniques, and procedures (TTPs) form the foundation of modern defense strategies. Unlike indicators of compromise (IOCs), TTPs are more stable, making them a reliable way to identify specific cyber threats. Here are some of the most commonly used techniques, according to ANY.RUN's Q3 2024 report on malware trends, complete with real-world examples. Disabling of Windows Event Logging (T1562.002) Disrupting Windows Event Logging helps attackers prevent the system from recording crucial information about their malicious actions. Without event logs, important details such as login attempts, file modifications, and system changes go unrecorded, leaving security solutions and analysts with incomplete or missing data. Windows Event Logging can be manipulated in different ways, including by changing registry keys or using commands like "net stop eventlog". Altering group policies is another common method. Since many detection mechanisms rely on log analysis to identify s...

The setup can range from a straightforward virtual machine using VirtualBox to a more intricate network of interconnected machines and actual networking hardware. But in this article, we'll look at building a lab tailored for static analysis, so what we will need is a secure environment where we can run disassemblers, edit binary files and debug. There are a couple of ways we can go about creating it: 1 — Virtualization Perhaps the simplest way to create a secure and isolated environment is by using a virtual machine....
How to Detect New Threats via Suspicious Activities

How to Detect New Threats via Suspicious Activities

Feb 20, 2023 Malware Analysis / Threat Detection
Unknown malware presents a significant cybersecurity threat and can cause serious damage to organizations and individuals alike. When left undetected, malicious code can gain access to confidential information, corrupt data, and allow attackers to gain control of systems. Find out how to avoid these circumstances and detect unknown malicious behavior efficiently.  Challenges of new threats' detection While known malware families are more predictable and can be detected more easily, unknown threats can take on a variety of forms, causing a bunch of challenges for their detection: Malware developers use polymorphism, which enables them to modify the malicious code to generate unique variants of the same malware.  There is malware that is still not identified and doesn't have any rulesets for detection. Some threats can be Fully UnDetectable (FUD) for some time and challenge perimeter security.  The code is often encrypted, making it difficult to detect by signature-...
