In a world increasingly governed by digital systems, a new type of warfare has emerged. Fought in the shadows of the web, it’s a battle waged not with bullets and bombs, but with bytes and bits. Welcome to the realm of network hacking, where the lines between legality and criminality blur, and the battlegrounds are not physical territories but intricate lattices of interconnected devices.

The specter of network hacking looms large over our digital society. Yet, despite the pervasive nature of this threat, few truly understand the mechanisms of network hacking—the insidious techniques, the clandestine tools, and the silent, unseen attacks that can compromise our most trusted systems. This article serves as a lens to bring this mysterious world into focus, exploring the intricacies of network hacking and illuminating the shadowy corners of the digital underworld.

What is Network Hacking?

Network Hacking is any attempt to compromise a network’s security. Hackers are generally curious programmers who enjoy getting into the nuts and bolts of how computer systems and networks (usually TCP/IP) work. Hackers usually guard their identity carefully and use purely technological means to try to break into a system.

Hacking (network)

Hackers generally find sufficient satisfaction with the mere act of defeating a network’s security system, and they pride themselves on not damaging or taking advantage of the data stored in the systems they hack. This unwritten “hacker’s code” distinguishes hacking from cracking, which is the attempt to steal revenue from software publishers by removing software protection functions such as expiration dates and installation codes, and from phreaking, a more destructive activity that usually involves both technological hacking and some form of deception through personal contact with the target organization with the aim to defraud.

Types of Networking Hacking

Networking Hacking is an offensive branch of computer security related to networks hacking and the penetration of a target via the networking services or equipment.

Examples of network hacking tools include:

  • Kismet (Wireless Hacking)
  • Sniffing & Monitoring
  • THC-Hydra
  • Infernal Twin
  • Firesheep

Black, White, and Grey Hat Hacking

Not all hackers are intentionally bad. When used in mainstream media, the word, “hacker,” is usually used in relation to cybercriminals, but a hacker can actually be anyone, regardless of their intentions, who utilizes their knowledge of computer software and hardware to break down and bypass security measures on a computer, device or network. Hacking itself is not an illegal activity unless the hacker is compromising a system without the owner’s permission. Many companies and government agencies actually employ hackers to help them test and secure their systems.

Hackers are generally categorized by the type of metaphorical “hat” they don: “white hat”, “grey hat”, and “black hat”. The terms come from old spaghetti westerns, where the bad guy wears a black cowboy hat, and the good guy wears a white hat. There are two main factors that determine the type of hacker you’re dealing with: their motivations, and whether or not they are breaking the law.

Black Hat Hacking

Black Hat hackers are responsible for writing malware, which is a method used to gain access to these systems. Their primary motivation is usually for personal or financial gain, but they can also be involved in cyber espionage, protest, or perhaps are just addicted to the thrill of cybercrime.

White Hat Hacking

White hat hackers choose to use their powers for good rather than evil. Also known as “ethical hackers,” white hat hackers can sometimes be paid employees or contractors working for companies as security specialists who attempt to find security holes via hacking. White hat hackers perform penetration testing, test in-place security systems, and perform vulnerability assessments for companies.

Grey Hat Hacking

As in life, there are grey areas that are neither black nor white. Grey hat hackers are a blend of both black hat and white hat activities. Often, grey hat hackers will look for vulnerabilities in a system without the owner’s permission or knowledge. If issues are found, they will report them to the owner, sometimes requesting a small fee to fix the issue. If the owner does not respond or comply, then sometimes the hackers will post the newly found exploit online for the world to see.

The term “hack”

The term “hack” is also used to refer to any temporary or inelegant solution to a networking problem, as in, «I hooked in the old hub as a repeater just as a temporary solution – I know it’s a hack, but it should do fine until we can buy something better».

Real Stories from the Digital Underworld: Famous Network Hacks

To truly comprehend the scale, audacity, and potential repercussions of network hacking, it’s worth delving into some of the most famous cases in history. These real-life tales of digital subterfuge offer valuable insights into the tactics hackers employ and underscore the need for robust network security.

Sony Pictures

One of the most infamous network hacking incidents was the breach of Sony Pictures Entertainment in 2014. In this unprecedented attack, a hacker group known as ‘Guardians of Peace’ released confidential data from the Sony Pictures network. The leaked data included personal emails, employee data, executive salaries, and unreleased films. It caused widespread havoc and embarrassment, emphasizing that even well-established corporations could fall prey to the formidable force of network hacking.

Microsoft’s WannaCry Ransomware attack

Another remarkable instance of network hacking that shook the world was the WannaCry ransomware attack in 2017. It leveraged a vulnerability in Microsoft’s Server Message Block protocol and encrypted the victim’s files, demanding a ransom payable in Bitcoin. The attack had a global impact, affecting organizations across 150 countries, including the UK’s National Health Service, telecom companies, and major logistics operators. This demonstrated the potential for network hacks to cross geographical boundaries and affect institutions that form the backbone of our societies.

Equifax Breach

The breach of Equifax, a consumer credit reporting agency, in 2017 stands as a stark example of the high stakes in network security. Hackers exploited a vulnerability in a web application framework and managed to access names, Social Security numbers, birth dates, addresses, and in some cases, driver’s license numbers of 143 million consumers. The Equifax breach serves as a chilling reminder of the kind of sensitive personal information that can be exposed in these attacks.

U.S. Office of Personnel Management

One of the most significant and sophisticated network hacks in history targeted none other than the U.S. government. In 2014 and 2015, alleged Chinese hackers breached the U.S. Office of Personnel Management, exfiltrating sensitive data of around 22 million people. The data included security clearance information, fingerprints, and other personally identifiable information, highlighting the national security implications of network hacking.

These incidents are not just historical footnotes; they’re potent reminders of the havoc that network hacking can wreak. Each story underscores a unique aspect of network hacking—the scale, the sophistication, the potential damage, and the range of potential targets. They serve as sobering wake-up calls, spurring us to prioritize network security and stay vigilant in the face of potential threats. As these tales from the digital underworld illustrate, network hacking is not just an abstract concept but a real and present danger in our increasingly interconnected world.
