doxxing

From dox, for documents. Finding and publishing documents with personal (but public) information about a target.

“Doxing consists of aggregating as much information on an individual or organization using social media networks, web search engines, social engineering, basic deduction skills, and password cracking methods...

Once enough information is gathered on a targeted individual or organization, the attacker openly publishes the target’s personal photos, personally identifiable information, and any other information, including information on family members, in retaliation for a perceived offensive action the target or the target’s organization may have taken.” [NORRIS]

EXIF
Digital image data stored in image files by cameras, scanners, smartphones and computers. Often includes time, date, and exact geographic location the photo was taken.
SWATting
“Swatting is the tricking of any emergency service (via such means as hoaxing a 9-1-1 dispatcher) into dispatching an emergency response based on the false report of an on-going critical incident” [WIKI2]
Whois
“WHOIS (pronounced as the phrase who is) is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block” [WIKI1]
