According to an NSA document leaked to {{Lang|de|[[Der Spiegel]]}}, the NSA sometimes swaps the monitor cables on targeted computers with a bugged monitor cable to allow the NSA to remotely see what is being displayed on the targeted computer monitor.<ref>[http://www.spiegel.de/international/world/catalog-reveals-nsa-has-back-doors-for-numerous-devices-a-940994.html Shopping for Spy Gear: Catalog Advertises NSA Toolbox, dec 2013] {{webarchive|url=https://web.archive.org/web/20150906100506/http://www.spiegel.de/international/world/catalog-reveals-nsa-has-back-doors-for-numerous-devices-a-940994.html |date=6 September 2015 }}</ref>

[[Van Eck phreaking]] is the process of remotely displaying the contents of a CRT or LCD by detecting its electromagnetic emissions. It is named after Dutch computer researcher Wim van Eck, who in 1985 published the first paper on it, including proof of concept. While most effective on older CRT monitors due to their strong electromagnetic emissions, it can potentially apply to LCDs as well, although modern shielding techniques significantly mitigate the risk. Phreaking more generally is the process of exploiting telephone networks.<ref>Definition of terms clarified and discussed in Aaron Schwabach, ''Internet and the Law: Technology, Society, and Compromises, 2nd Edition'' (Santa Barbara CA: ABC-CLIO, 2014), 192–3. {{ISBN|9781610693509}}</ref>
