Book Description

In May 2021, Jim Gosler, known as the Godfather and commander of US agencies’ cyber offensive capability, said, ''Either the Intelligence Community (IC) would grow and adapt, or the Internet would eat us alive.'' Mr Gosler was speaking at his retirement only several months before the terrorist attacks of 9/11. He possibly did not realise the catalyst or the tsunami that he and his tens of thousands of US IC offensive website operatives had created and commenced. Over the last two decades, what Mr Gosler and his army of Internet keyboard warriors created would become the modus operandi for every faceless, nameless, state-sponsored or individual cybercriminal to replicate against an unwary, ill-protected, and ignorant group of executives and security professionals who knew little to nothing about the clandestine methods of infiltration and weaponisation of the Internet that the US and UK agencies led, all in the name of security. This book covers many cyber and ransomware attacks and events, including how we have gotten to the point of massive digital utilisation, particularly during the global lockdown and COVID-19 pandemic, to online spending that will see twice the monetary amount lost to cybercrime than what is spent online. There is little to no attribution, and with the IC themselves suffering cyberattacks, they are all blamed on being sophisticated ones, of course. We are witnessing the undermining of our entire way of life, our economies, and even our liberties. The IC has lots to answer for and unequivocally created the disastrous situation we are currently in. They currently have little to no answer. We need—no, we must demand—change. That change must start by ensuring the Internet and all connections to it are secure and no longer allow easy access and exfiltration for both the ICs and cybercriminals.

Book Description

Ransomware is a type of malicious software that prevents victims from accessing their computers and the information they have stored. Typically, victims are required to pay a ransom, usually using cryptocurrency, such as Bitcoin, to regain access. Ransomware attacks pose a significant threat to national security, and there has been a substantial increase in such attacks in the post-Covid era. In response to these threats, large enterprises have begun implementing better cybersecurity practices, such as deploying data loss prevention mechanisms and improving backup strategies. However, cybercriminals have developed a hybrid variant called Ransomware 2.0. In this variation, sensitive data is stolen before being encrypted, allowing cybercriminals to publicly release the information if the ransom is not paid. Cybercriminals also take advantage of cryptocurrency’s anonymity and untraceability. Ransomware 3.0 is an emerging threat in which cybercriminals target critical infrastructures and tamper with the data stored on computing devices. Unlike in traditional ransomware attacks, cybercriminals are more interested in the actual data on the victims’ devices, particularly from critical enterprises such as government, healthcare, education, defense, and utility providers. State-based cyber actors are more interested in disrupting critical infrastructures rather than seeking financial benefits via cryptocurrency. Additionally, these sophisticated cyber actors are also interested in obtaining trade secrets and gathering confidential information. It is worth noting that the misinformation caused by ransomware attacks can severely impact critical infrastructures and can serve as a primary weapon in information warfare in today’s age. In recent events, Russia’s invasion of Ukraine led to several countries retaliating against Russia. A ransomware group threatened cyber-attacks on the critical infrastructure of these countries. Experts warned that this could be the most widespread ransomware gang globally and is linked to a trend of Russian hackers supporting the Kremlin’s ideology. Ensuring cyber safety from ransomware attacks has become a national security priority for many nations across the world. The evolving variants of ransomware attacks present a wider and more challenging threat landscape, highlighting the need for collaborative work throughout the entire cyber ecosystem value chain. In response to this evolving threat, a book addressing the challenges associated with ransomware is very timely. This book aims to provide a comprehensive overview of the evolution, trends, techniques, impact on critical infrastructures and national security, countermeasures, and open research directions in this area. It will serve as a valuable source of knowledge on the topic.
