How Malware Hides From You
Malware, or malicious software, infects target computers, injecting malicious instructions and compromising system integrity. Malware’s construction allows it to integrate malicious actions into legitimate software. Such malicious actions may let attackers steal passwords or damage sensitive data. Malware may be utilized on an individual level against users or on an organizational level against institutions or businesses, exemplified by the ransomware attacks against the University of California, San Francisco. While the specific infection mechanism varies greatly depending on the malware type, malware as a whole utilizes advanced software techniques to stay hidden from detection software. Simple methods like encryption obfuscate malware from traditional detection methods used by most anti-malware. More advanced techniques like polymorphism and metamorphism allow malware to manipulate itself to increase obfuscation, much like a biological virus. The ever-increasing complexity of malware heightens the importance of developing countermeasures to the growing problem. Users must also maintain vigilance and follow good computing practices to counter malware’s development.
