In his reaction to the news that two YouTube and Twitter accounts belonging to the U.S. military were hijacked by ISIS supporters, Ken Westin, senior security analyst at Tripwire, says:
"It is not a coincidence that this attack occurred just as Obama announced new cyber safeguards. The CyberCaliphate to date has been adept in utilizing website defacements as a means of propaganda in support of ISIS. The compromise of both the Central Command Twitter and Youtube accounts is an escalation that should cause concern for the U.S. Government. The fact they were able to compromise the accounts should force the government to reevaluate their security policies when it comes to social media. Google and Twitter both provide two-factor authentication, it would be interesting to know if this was deployed on these accounts, if not it would show a serious lapse in security.
Looking at the data that was posted on the Twitter account, much of it appears to be data that was posted publicly elsewhere, so the claims that the CyberCaliphate has compromised military and government devices may not be true. However even if military systems and devices have not been compromised, the objectives of the Cyber Caliphate are still achieved thanks to the media frenzy that the compromise and data posted generates.
