INDICATOR-OBFUSCATION -- Snort detected a system behavior that suggests the system has been affected by malware. That behavior is known as an Indicator of Compromise (IOC). The symptoms could be a wide range of behaviors, from a suspicious file name to an unusual use of a utility. Symptoms do not guarantee an infection; your network configuration may not be affected by malware, but showing indicators as a result of a normal function. This alert specifically refers to a method of disguising code, known as obfuscation. Obfuscation methods are used to perform innocent convenience tasks (for instance, Javascript used to condense Jquery scripts, or a compiler using obfuscation to protect the full code for NDA reasons), or it could be used to hide an attack.
