Per CNN..
DIGITA SHADOW joins other cyber groups like Anonymous to fight the terrorist cyber war
Made up of ex military, IT Specialists.
Digita Shadow/GHOST SECURITY, says they only hack when lives are at stake.
"Ghost Security differentiates itself from the vast and often disjointed hacktivist collective Anonymous, which has also declared war on ISIS and claims to have taken down pro-ISIS Twitter accounts. A handful of members were previously part of Anonymous, including one of the leaders, who goes by the name "DigitaShadow." He says Ghost Security is small and more focused.
"We have structure and leadership," he told CNNMoney. "We also have a lot of counterterrorism experience. We have translators, linguists, research analysts on hand to analyze all the data that we receive."
