The Libyan Cyber Army hasn’t been very active lately, but they have managed to breach a few high-profile websites over the past months. For instance, they defaced a NATO subdomain, and a couple of Libyan government websites.
In December 2013, they managed to deface an Al Arabiya subdomain. That particular page is still online.
