Ghost (communication network)

Ghost (communication network) is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ghost (communication network) rather than just read about it. In short: Ghost was an Australian-based communications network and service provider that offered modified smartphones allowing encrypted communications among subscribers. Background Ghost was originally created around 2015.

Key takeaways

Ghost (communication network) belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Ghost (communication network) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Ghost (communication network) from memory before moving on to harder problems.

Reference excerpt

Ghost was an Australian-based communications network and service provider that offered modified smartphones allowing encrypted communications among subscribers.

Background Ghost was originally created around 2015.

Devices The modified handsets were sold for A$2,350 each which paid for the device and a six-month subscription.

Infiltration The infiltration was led by the FBI, the National Gendarmerie of France, along with Europol, the Australian Federal Police, the Royal Canadian Mounted Police, an Garda Síochána, Icelandic police, Swedish police, Dutch police, and the Italian Central Directorate for Anti-Drug Service. The operation to infiltrate the network was codenamed "Operation Kraken". The raids took place on 17 and 18 September 2024.

Lead suspect On 18 September Australian national Jay Je Yoon Jung of Narwee, New South Wales faced five charges relating to the development and administration of Ghost in a Sydney court.

Impact

Europol Catherine De Bolle, head of Europol said "Today we have made it clear that no matter how hidden criminal networks think they are, they can't evade our collective effort. Law enforcement from nine countries, together with Europol, have dismantled a tool which was a lifeline for serious organized crime. This operation is what Europol is all about: Turning collaboration into concrete results by bringing together the right people, tools, and expertise to address every aspect of this complex operation. The work carried out is part of our ongoing commitment to tackling organized crime wherever it operates. I want to extend my gratitude to all our global partners who played a vital role in making this operation a success."

Australia Australian Federal police believe there were around 376 handsets were active in Australia.

Ireland An Garda Síochána believed there were 42 of the devices active at the time of the raids. The head of the Garda Drugs and Organised Crime Bureau, Justin Kelly said that Ireland had the second largest userbase of Ghost devices in the world and that four organised crime gangs were targeted through access to Ghost. He also said "During this operation, we targeted four Irish organized crime groups who were involved in drugs trafficking, frequently using violence and intimidation to enforce their illicit trade" and "Most significantly, we have dismantled a primary drugs trafficking route into our country, and in doing so have seized drugs with an approximate street value of €16 million ($17.82 million). We deployed over 300 specialist officers and searched 33 premises across the country during this operation. Our activity to date has resulted in 11 arrests and the seizure of €350,000 ($389,830) in cash, and I can assure you that there will indeed be further arrests. During our operation, we also targeted the key facilitators of this encrypted phone network, and importantly, seized a number of the suspect handsets." He declined to say whether the Kinahan Organised Crime Group were one of the four gangs targeted but reckoned that those targeted were of "extremely high value".

Italy Europol said that one member of Sacra Corona Unita had been arrested. They were not named but were said to be a high-ranking figure and were wanted since 2023.

Worked examples

Example 1 — a first encounter with Ghost (communication network)

Start with the simplest possible case. Write down what Ghost (communication network) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ghost (communication network) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ghost (communication network) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ghost (communication network)

In research: Ghost (communication network) appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ghost (communication network) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ghost (communication network) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Defunct technology companies of Australia, Networks, so understanding it makes those chapters shorter.
In everyday life: Look for Ghost (communication network) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
