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-based security solutions.
- Malware authors may use a “low and slow” approach, which involves sending a small amount of malicious code across a network over a long time, which makes it harder to detect and block. This can be especially damaging in corporate networks, where the lack of visibility into the environment can lead to undetected malicious activity.
