White House CIO, Security Expert: Democrats Targeted by Terrorists. Digital Tools Can Expose Culprit This bitch is hawking her wares as a cyber expert, so take it for what it's worth. U.S. authorities have identified at least six suspicious packages mailed to CNN, Obama, Clinton, and other leading Dem figures since Monday. But the question remains -- who's to blame for this terrorist attack on domestic soil? And how do authorities start piecing it together? Former White House CIO and CEO of leading cybersecurity firm Fortalice Solutions Theresa Payton says that -- when it comes to identifying the culprit -- the devil is likely in the digital details.   According to Theresa --   •	There is a digital patchwork that law enforcement officers can use to get a fuller picture of who's responsible here;  •	The place they'll likely start is the mail service -- every piece of mail sent via the U.S. Postal Service is digitally scanned, and an image is kept on file. In cases like this, the Postal Service can provide photos and other support to law enforcement officials, and -- using those resources -- they can piece together more information about date, time, and the geographic origin of the packages;  •	Investigators can use that information to cross-reference against surveillance footage that may show who dropped the packages off or where they were picked up;  •	In addition, law enforcement officers can investigate the package and its contents for more digital clues about where, how, and when items were purchased;  •	They can comb chat boards, message rooms, social media and other communication to scope out social leads;  •	Finally, law enforcement can subpoena social media companies, search engines, and more to gain access to additional information that isn't readily and publicly available.   •	I'd recommend setting up a tip line or electronic submission process for any leads relating to the incident;
