Anonymity is a key ingredient when performing our attacks, unless we don't mind someone being able to trace us back to our location and giving up our position. Because of this, we need a way to hide or mask where we are coming from. This approach is perfect for a proxy or groups of proxies if we really want to make sure we don't leave a trail of breadcrumbs. When using a proxy, the source of an attack will look as though it is coming from the proxy instead of the real source.
Layering multiple proxies can help provide an onion effect, in which each layer hides the other, and makes it very difficult to determine the real source during any forensic investigation.
Proxies come in various types and flavors. There are websites devoted to hiding our source online, and with a quick Google search, we can see some of the most popular, such as hide.me, Hidestar, NewIPNow, ProxySite, and even AnonyMouse. Here is a screenshot from the NewIPNow website:
