Malwarebytes looks at malware techniques to prevent removal and analysis. Malware achieves this using obscure filenames, modifying file attributes, or operating under the pretense of legitimate programs and services. In more advanced cases, the malware might attempt to subvert modern detection software (i.e. MBAM) to prevent being found, hiding running processes and network connections. Despite advances in modern malware, dirty programs cant hide forever. When malware is found, it needs some additional layers of defense to protect itself from analysis.”]
