What is a dead drop?

Dead Drop or Dead Letterbox is a place that two people can use to transmit information without meeting personally. A classic dead drop is a common public location where arrivals and departures would not be observed, the information was hidden in matters such as baskets, toilet tanks, holes in tree trunks, etc. The espionage community has also developed more close -drop systems that rely strongly on technology. One of the main advantages of using a public dead drop instead of meeting information is that dead drop users can minimize the appearance of suspicious activity. For example, a walk in the park and sitting on the bench, and there is absolutely normal activation that may not arouse too much suspicion, while throwing into the bush and conversation with someone can be perceived as unusual.

dead drops can also be used to protect members of the spiHeading groups. For example, two cells could transmit information with a dead drop without meeting each other, so that if members of one of one cell were captured, they cannot reveal the identity of the other cell members. Dead drop users can also visit, avoiding a regular schedule that observers could note.

When people leave information in a dead decline, they often leave signals in the area to warn the person they communicate with, saying there is something in a dead drop. These signals may take the form of chalk brands, strategically placed rocks and other fine changes in an environment that would be difficult to interpret for external obmers. Clever agents also regularly change their signals and places of dead drops to avoid creating a pattern that could be used to identify them.

Modern dead drop tends to be much more sophisticated than Knothol in a tree. Many dead drops today are completely electronic and create situacI, when no one has to visit a physical website. For example, agents could use a wireless router as a dead drop and code messages that users who know how they know how to know.
