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.

Cross Site Scripting (XSS)
Cross Site Scripting (XSS) attackers send malicious input to a site that does not validate the input, usually in the form of a script. The application sends the malicious code to the browsers of other users, which will execute the script unknowingly. The malicious code uses the trust of the host website to access cookies, session tokens, or other sensitive information. There are multiple types of XSS, including Stored, Reflected, and DOM based.
