A dead drop, also known as a dead letter box, is a type of espionage tradecraft used to transfer objects or information between two people (for example, a case officer and an agent, or two agents) utilizing a concealed location. The term "dead drop" comes from the fact that if you put something in a dead drop you hide it from view; therefore it is "dead" material.
Dead drops are commonly used by spies working for governments or secret organizations. Spies use them to pass notes back and forth, conceal small items such as cameras or microphones, and, in some cases, communicate via radio waves. They can also be used for brainstorming sessions or as a way for agents to coordinate activities without being seen by their opponents.
Dead drops can be real or fake. Real ones are often hidden in obvious places such as under a rock or in a tree trunk. Fake ones are usually made out of plastic or wood and typically have an opening on top where you can place an item to hide its presence.
In order to use a dead drop, you first need to find one. This might not be easy since most dead drops are not listed on any map. You also need to make sure that nobody will stumble upon it while looking for other things.
A dead drop spike, like a microcache, is a concealing mechanism. It has been used to conceal money, maps, papers, microfilm, and other materials since the late 1960s. The term comes from the practice of placing a spike in the ground with each item concealed on or under it.
Spies use dead drops for two main purposes: to receive information and supplies by courier without being detected by surveillance; and as a safe place to store documents that might be damaged if kept at home or office. Dead drops are also useful for sending and receiving secret messages. In espionage, a dead drop is any covert location where intelligence agents can deposit or retrieve items without being observed by counterintelligence officers or security guards. Agents use dead drops to exchange information and materials without being detected by surveillance equipment such as cameras or listening devices.
Items deposited in a dead drop include but are not limited to: documents, photographs, cassette tapes, memory sticks, software programs, weapons, and illegal substances. Items retrieved from a dead drop include but are not limited to: more documents, photographs, etc.
Dead drops can be found all over the world in public and private places. Security guards sometimes place small containers in doorways for employees to leave notes for one another or pick up important documents.
Hidden Symbols To conceal potentially sensitive material, British agents put rolled-up letters and tiny notes in a variety of holsters. For example, hollowed out quills of huge feathers used as writing instruments may conceal a tightly wound up message. Or a spy might wrap a piece of string around a small object to hide its shape.
Spies also use codes, words or phrases that only other people understand. For example, a secret message could be encoded into the names of towns or cities. A decoder would know what it was supposed to do with these clues.
Finally, spies can disguise themselves by wearing false beards or hair styles, glasses with lenses of different colors, tattoos, or body modifications (such as piercings).
Spies cannot always escape scrutiny, however. If an agent is using a public place such as a bus or train, she should not act suspiciously. People will notice such behavior and ask questions.
Spies must be careful not to compromise national security by disclosing secrets in conversations or online. Even if they think no one is listening, they still have to be careful about saying too much.
The goal of the game is to collect numerous secret objects in a briefcase and depart the building by an airport entrance before the opponent player or the timer runs out. Each spy has a personal countdown meter that is depleted by 30 seconds for every kill. If the player dies, the game ends immediately with the losing spy being eliminated from the game.
Spy vs. Spy was developed by Matt Griffith and published by Atari under their Indie Games label. It was released for Microsoft Windows on October 4, 2009 and OS X on April 5, 2010. A version for Android was also released later that year.
The game is based on a short story "Of Rats and Men" by Edgar Allan Poe, which can be found online at various sites. The game itself is very linear but offers multiple paths through each level.
Spy vs. Spy received generally positive reviews from critics who praised its art style and atmosphere but some criticized the lack of depth in the gameplay experience.
This transmission contained predetermined code phrases from Washington to Tallmadge, to which Tallmadge replied in code. The messages were then buried in commodities that Roe carried back to Setauket and hid on Abraham Woodhull's property, from whence the messages were eventually recovered. This method of communication was secure because only people in possession of the secret codes could decipher it.
After Cornwallis' surrender at Yorktown, the war came to an end. But the danger was not over for America's new government. In fact, it had just begun. Over the next few years, several groups of British spies would arrive in New York looking for jobs as customs agents or other government positions. If they were caught, they would be executed.
The most famous spy in American history was John Andros, first royal governor of Maryland. In 1694, he hired a young man named Samuel Morison to be his secretary. Sam was the son of a wealthy Scottish merchant who had come to work for a friend in Baltimore. Little did he know this friend was actually the secretary of the king's deputy in America! Under the name "Culper," Sam went to work for Andros by pretending to join his band of colonial rebels. He learned their plans and reported them back to his boss, who used his information to help win the war.
Steganography Steganography falls under the concept of "conceal its existence." Cyber thieves adopt this strategy because the data they wish to conceal can be buried in plain sight. This is accomplished by embedding it in another seemingly innocuous file. When you open this image, for example, you will see a photo of some rocks.
This technique is often used to conceal malware. When you download this picture, for example, you will install ransomware on your computer without even knowing it.
Thieves use steganography to hide evidence of data theft and fraud. They may use this approach to cover their tracks when they upload illegal content or steal money from banks. It also can be employed to conceal personal information such as credit card numbers or social security numbers.
Thieves use software tools to hide evidence of data theft and fraud. For example, they may use steganography to cover their tracks when they upload illegal content or steal money from banks.
Spying or deploying spies is an example of espionage. The government frequently uses this to obtain information. Spies can be foreign agents, who are employees of a country's intelligence service, or domestic informants, who may work for the government or a private company.
In addition, a country may use covert actions, which include military operations and other activities designed to influence the behavior of individuals or groups without their knowledge or consent. These activities may be carried out by any organization or individual that is not part of the official foreign policy apparatus of the country involved.
A country may also engage in black propaganda, which is published information that is intended to deceive the public into believing that it originates from a trusted source. This can be used to distract people from what other events are happening, such as the Iraq War for America during 2004-2009.
Finally, a country may engage in white propaganda, which is published information that is intended to deceive the public into believing that it originates from an untrustworthy source. This can be used to promote one idea over another or even lie about an event that has already taken place. For example, Germany used white propaganda to create the impression that Jews were responsible for the financial crisis of 2007-2008.
