Netflix’s Zero Day has been released, and here are all the codenames from throughout the show, explained. The cast of Zero Day is absolutely massive, with there being a variety of government employees, wealthy financial investors, and more affected by the Zero Day Attack. While the Zero Day Commission discovers the codenames of the individuals involved, they don’t know who the actual conspirators are until the end of the series. Cracking the codenames was one of the biggest steps in finding the culprits, and here’s who each of the call signs belong to in Zero Day.

Zero Day tells the story of Robert De Niro’s George Mullen, the former president of the United States. After a nationwide cyber attack causes countless deaths and destabilizes the country, George Mullen is appointed as the head of the Zero Day Commission, a task force that is charged with finding the individuals behind the attack. However, finding the culprits becomes a much more challenging task than he initially anticipated.

Tyrone44, Gekko, & More

The Zero Day Commission makes a major discovery near the end of Zero Day‘s story. In episode 5, the team uses the wreckage from the abandoned Reaper farm to discover that the Zero Day attackers have been communicating with each other via an analog radio. The Zero Day Commission gains access to their channel, cracks their codes, and begins to communicate with the attackers, with them learning the various codenames and call signs that each of the perpetrators is using.

Tyrone44 turns out to be Robert Lyndon, one of the main perpetrators in the attack. Monica Kidder and the woman who works for her use the call sign Athena, something that is seen later in episode 5. Blue Hawk is the superior who talks to George Mullen’s Red Rooster, with him turning out to be Blake Felton. The individuals using the radio transmission also referred to some figures outside of the conspiracy, with Gekko referring to Roger Carlson and Emmett Kelly referring to George Mullen.

How The A.M. Radio Allowed The Conspirators To Avoid Detection

It Wasn’t As Advanced As The Commission Expected

The conspirators’ usage of the A.M. radio may seem like an odd choice, but it was actually the only way that they could have pulled off the attack. As some members of the Zero Day Commission explain, the culprits knew that the government’s advanced technological monitoring would lead to any communications over computers being caught.

Thus, the Zero Day attackers decided to use A.M. radios, believing that it would be a more secure way to communicate. The A.M. radios combined with code names and a coded language allowed them to get away with it for a while, with them not getting caught until the end of Zero Day.
