Helium is a chemical element represented by the symbol He and atomic number 2. In cybersecurity, 'Helium' does not refer to any specific technology, threat, or tool. However, it is important to note that some software or projects might use 'Helium' as a codename or product name, but these are unrelated to the element itself. Helium, as a gas, is colorless, odorless, tasteless, non-toxic, and inert. It is commonly used in scientific applications, balloons, and as a cooling medium, but it has no direct relevance to cybersecurity concepts, attacks, or defenses.
