Unknown malware poses a significant cybersecurity risk and can cause significant harm to both organizations and individuals. Malicious code can gain access to confidential information, corrupt data, and allow attackers to take control of systems if it goes undetected.
Learn how to avoid these situations and effectively detect unknown malicious behavior. Challenges in detecting new threats# While known malware families are more predictable and can be detected more easily, unknown threats can take on a variety of forms, posing a slew of detection challenges:
- Malware developers employ polymorphism, allowing them to modify the malicious code to create distinct variants of the same malware.
- There is malware that has yet to be identified and does not have any detection rulesets.
- Some threats can be Fully UnDetectable (FUD) for a period of time, putting perimeter security at risk.
- The code is frequently encrypted, making signature-based security solutions difficult to detect.
- Malware authors may employ a “low and slow” strategy, which entails sending a small amount of malicious code across a network over a long period of time, making it difficult to detect and block. This is especially dangerous in corporate networks, where a lack of visibility into the environment can result in undetected malicious activity.
