The U.S. Marine Corps on Sunday urged “vigilance” among staff after the Islamic State of Iraq and Syria (ISIS) group published the alleged names and addresses of 100 military personnel and urged supporters to kill them.
“Vigilance and force protection considerations remain a priority for commanders and their personnel,” U.S. Marine Corps Lt. Col. John Caldwell said in a statement.
“It is recommended Marines and family members check their online/social footprint, ensuring privacy settings are adjusted to limit the amount of available personal information.”
The warning came after a group calling itself the Islamic State Hacking Division put the allegedly hacked information about members of the air force, army and navy, included photos and ranks, on the Internet, according to monitoring group SITE Intelligence.
The hacking group said it took the information from government servers, databases and emails and called on its followers to mount attacks.
A defense source, however, told The New York Times most of the information was in fact available in public records and did not appear to have been hacked from government servers.
“With the huge amount of data we have from various different servers and databases, we have decided to leak 100 addresses so that our brothers residing in America can deal with you,” the group wrote.
