Example of Locky ransomware.

Locky is ransomware malware released in 2016. It is delivered by email and after infection will encrypt all files that match particular extensions.

After encryption, a message (displayed on the user's desktop) instructs them to download the Tor browser and visit a specific criminal-operated Web site for further information.

The current version, released in December 2016, utilizes the .osiris extension for encrypted files.

Many different distribution methods for Locky have been used since the ransomware was released. These distribution methods include Word and Excel attachments with malicious macros,DOCM attachments and zipped JS Attachments.

JADE Japanese Cipher machine by brewbooks

1 1

During World War 2, this model of the Japanese Type-97 cipher machine was known to American cryptanalysts as JADE. JADE was one of three varieties of Japanese machines that used a series of telephone selector switches to encipher r decipher top-level messages. The other two machines were known by the American designators CORAL and PURPLE. The Top Secret messages enciphered by JADE, CORAL, and PURPLE machines and transmitted by radio were intercepted and decrypted by American Army and Navy personnel. The information gained by this source was of the highest level of importance and was instrumental in the Allied victory in the Pacific.

Although no PURPLE cipher machine was ever captured intact, it is believed that PURPLE looked very much like JADE. This JADE machine was captured in Saipan in June, 1944.

Purple

In 1937, the next generation 97-shiki injiki(九七式印字機) ("Type 97 print machine") was completed. The Ministry of Foreign Affairs machine was the Angooki Taipu-B (暗号機タイプB) ("Type B Cipher Machine"), codenamed Purple by United States cryptanalysts.

The chief designer of Purple was Kazuo Tanabe (田辺一雄). His engineers were Masaji Yamamoto (山本正治) and Eikichi Suzuki (鈴木恵吉). Eikichi Suzuki suggested use of stepping switch instead of the more troublesome half-rotor switch.

Clearly, the Purple machine was more secure than Red, but the Navy did not recognize that Red had already been broken. The Purple machine inherited a weak point from the Red machine, namely vowel-consonant separate encryption, which was called "sixes-twenties" by the US Army SIS.

Vera Wilde, artist-in-residence at Hack42. Because Art & Science!

Hackerspace Hack42 is proudly hosting a new artist-in-residence. Dr. Vera K. Wilde (PhD PoliSci) is a (former) Harvard Kennedy School researcher. She is working on re-branding the Dark-Web to the EDTR-web, a place for Expressing, Dissenting, Teaching and Resisting.

The EDTR-web is using technologies like TOR and encrypted communications tools to create a place of freedom where centralised power cannot reach.

Vera will be using arts (oil painting and songwriting) as well as writing and political science methods to define and develop the EDTR-web as a social space and technological phenomenon.

This is our second photo-shoot together. We have great chemistry and it's loads of fun to shoot with her.

We got to play with a few props, listen to some music and experiment with light and posing.

James Comey Director Federal Bureau of Investigation discusses the impact of technology on the work of law enforcement by Brookings Institution

Issues of privacy and security are at the forefront of public debate, particularly in light of recent national security disclosures and increasingly pernicious cyber attacks that target our personal information, our ideas, our money, and our secrets. But are privacy rights trumping public safety interests? And if so, at what cost? Has the post-Snowden pendulum swung too far in one direction?

On October 16, Governance Studies at Brookings hosted FBI Director James Comey for a discussion of the impact of technology on the work of law enforcement. Law enforcement officials worry that the explosion in the volume and the means by which we all communicate threatens its access to the evidence it needs to investigate and prosecute crime and to prevent acts of terrorism.

In particular, officials worry that the emergence of default encryption settings and encrypted devices and networks – designed to increase security and privacy – may leave law enforcement in the dark. Director Comey will talk about the need for better cooperation between the private sector and law enforcement agencies. He will also discuss potential solutions to the challenge of “going dark,” as well as the FBI’s dedication to protecting public safety while safeguarding privacy and promoting network security and innovation.

Enigma by Paul Hurst

1

The Enigma machines where commercially available at first. The German High Command tried a few various encryption machines before settling on Enigma. The machine is basically a button, battery, and light machine where pressing a key completes a circuit and lights a bulb.

By introducing wheels and millions of variable circuit paths, it is possible to alter which lettered lamp lights up when a key is pressed. As long as the same settings are used by both sender and receiver, the message will be both encoded and decoded by the same box.

The staff at Bletchley knew that Enigma Machines where being used by the Germans but they didn't know how they were set up. The settings where also changed every day. Without knowing these settings, they were unable to set up their machines in the same way which was needed in order to decrypt the messages back into plain text.

For example. If, using Enigma from the factory default settings (no alterations, no plugboard, all wheels at AAA), HELLO WORLD is encrypted as KCUBR KIDKN. If an operator at Bletchley typed KCUBR KIDKN into their Enigma Macine, also at factory default, the lamps would light up to spell HELLO WORLD.

The job of the code breakers was to work out a way of finding out which settings had been used. They did this by using logic, the powers of decuction, the laws of mathematics and, presumably lots of strong coffee.

Vint Hill in Warrenton, Virginia by Dwayne Moyers, Realtor

Vint Hill Road (Route 215) and Vint Hill Parkway. This was the United States Army Garrison, Vint Hill Farms Station. During the Cold War this area was home to the United States Army Intelligence and Security Command. It is now an area developed for commercial and residential use. The Federal Aviation Administration Systems Command Center, Rockwell Collins, and Silvermead at Vint Hill residential subdivision are a part of this converted military base.

Vint Hill was the name of a 1860 Italianate brick mansion built by Andrew & Bessie Low. It was a manor house that was part of 729 acres of farmland and pasture for cattle and sheep. Andrew Low was a citizen of the United Kingdom and was not interested in becoming involved in the affairs of the Civil War. Between the Battle of First Manassas until the surrender of the Army of Northern Virginia at Appomattox Court House, Andrew Low flew the Union Jack flag of Britain at the manor house. Although Fauquier County changed hands between the Union and the Confederacy during the war, the Vint Hill tract was mostly left alone. When most homes were destroyed by invading Union troops, both sides honored an agreement of neutrality with Britain. The only issue of trespass at Vint Hill during the Civil War was the 'Grapewood Encounter' as Confederate Cavalry Colonel John S. Mosby and Mosby's Rangers fought Union opposition at the back gate of Vint Hill.

In 1885, Vint Hill became known as Silvermead after its size was doubled and the architecture was changed to a Colonial Revival-Style country house to accommodate Douglas Low (oldest son) and his wife, Marie. In 1910 it was purchased by Mitchell Harrison and was the center for high society social events as the land was used to raise thoroughbred cattle and horses. In June 1942 the Vint Hill tract was purchased by the United States Government for $127,500. By December 1942 it was given the official title 'Monitoring Station Number One' housing 662 enlisted men working as radio intercept operators, encryption analysts, and radio repair technicians assigned to the Second Signal Service Battalion.

Important enemy transmissions were delivered directly from the only listening post serving the United States to military war planners in Washington, D. C. during World War II. Vint Hill also became the headquarters for training military intelligence officers. After World War II, the listening post became Vint Hill Field Station One intercepting electronic signals during the Cold War. In 1975 the mission at Vint Hill changed and the post was renamed 'United States Army Garrison Vent Hill Farms Station'. The base officially closed in 1997 during the realignment of military bases.

During World War II, VHFS served as a refitting station for units returning from combat before overseas deployment. In 1961, the U.S. Army Electronic Material Readiness Activity was moved to VHFS. In 1973, U.S. EPA took over operation of the photographic interpretation center from the Defense Intelligence Agency which was renamed the Environmental Photographic Interpretation Center (EPIC). The Army Material Command (AMC) became the major command for VHFS in 1987. VHFS is currently under the Major Subordinate Command of Communications-Electronics Command (CECOM) and was named to the Base Realignment and closure (BRAC) list in 1993.
