Hacking (cs192 report )
Hacking refers to activities aimed at exploiting security flaws to obtain unauthorized access to secured networks and personal information, often for malicious purposes. A brief history outlines some notable early hackers and exploits from the late 19th century to the early 2000s. Hackers are categorized as white hat (non-malicious), grey hat (beyond malicious intent), black hat (malicious with intent to harm), or script kiddies (non-experts using automated tools). Famous hackers like Kevin Mitnick, Kevin Poulsen, and Adrian Lamo are discussed in relation to their hacking activities and categorization. Ethical hacking is defined as a methodology to discover vulnerabilities by having professionals attempt authorized access to computer systems to evaluate security threats
All about Hacking
Hacking refers to activities aimed at exploiting security flaws to obtain unauthorized access to secured networks and private information. There are different types of hackers, including black hats who hack maliciously, white hats who are ethical hackers, and script kiddies who use tools created by black hats. Common hacking methods include password guessing, software exploitation, backdoors, and trojans. Once inside a network, a hacker can steal or modify files, install backdoors, and attack other systems. Intrusion detection and prevention systems can help monitor for hacking attempts. Hacking is a felony in most countries and can carry heavy fines and prison sentences if prosecuted.

Cyber terrorism
This document discusses the topic of cyber terrorism, including:
- Defining cyber terrorism as using computer technology and the internet to cause fear and disruption.
- Describing three types of cyber terrorism: simple unstructured attacks, advanced structured attacks, and complex coordinated attacks.
- Explaining some of the effects of cyber terrorism, such as financial damage, weakening a nation's security and economy, and potentially causing death by disrupting critical systems.
- Providing some statistics on cyber attacks and losses due to various types of attacks.
- Listing some examples of cyber attacks that have taken place worldwide, targeting things like banking systems, air traffic control, and power grids.
Cyber Terrorism
Cyberterrorism is the use of Internet based attacks in terrorist activities, including acts of deliberate, large-scale disruption of computer networks, especially of personal computers attached to the Internet, by the means of tools such as computer viruses.
Cyberterrorism is a controversial term. Some authors choose a very narrow definition, relating to deployments, by known terrorist organizations, of disruption attacks against information systems for the primary purpose of creating alarm and panic. By this narrow definition, it is difficult to identify any instances of cyberterrorism.
Cyberterrorism can be also defined as the intentional use of computer, networks, and public internet to cause destruction and harm for personal objectives.[1] Objectives may be political or ideological since this is a form of terrorism[citation needed].
There is much concern from government and media sources about potential damages that could be caused by cyberterrorism, and this has prompted official responses from government agencies.
External threats-to-information-system
External threats to information systems include malicious software and computer crimes. Malicious software, such as viruses, worms, trojans, and spyware, can steal data, delete files, and slow down computer performance. Computer crimes involve hackers monitoring online activity or committing identity theft and fraud. Common types of attacks include ransomware, SQL injection, and virus backdoors that aim to compromise systems and access sensitive information.

Cyber warfare ss
Cyber warfare is becoming an increasingly common method for nations to engage in conflict without direct military confrontation. As technology advances faster than international laws and regulations, cyber attacks present a new threat landscape. Nations are investing heavily in growing their cyber warfare capabilities due to concerns about vulnerabilities and a desire to gain strategic advantages over rivals. However, this cyber arms race risks escalating conflicts and reducing overall digital security.
Cyber Terrorism Presentation
1) The document discusses definitions of cyberterrorism since it is a relatively new concept. Cyberterrorism involves unlawful attacks against computers, networks, or stored information to intimidate or coerce for political or social goals.
2) The key factor in determining if an cyber attack is cyberterrorism or just hacking is the intentions and motivations of the attackers - specifically if they have political goals.
3) An example is given of a 14-year-old launching a virus possibly being viewed differently than a terrorist group launching an attack to further specific political objectives by disrupting infrastructure.
Ethical hacking
This document discusses ethical hacking and defines it as assessing a system's security vulnerabilities from the perspective of a hacker for legitimate purposes like security testing, with the owner's consent and without malicious intent. It outlines the types of hackers (black hat, white hat, grey hat), hacking process (footprinting, scanning, gaining access, maintaining access, covering tracks), why ethical hacking is needed (to protect from external attacks), and its advantages (finding security holes, preventing attacks) and disadvantages (requires trustworthy professionals which can be expensive).
Ethical hacking
Hacking involves gaining unauthorized access to computer systems or networks, and can be done for malicious or ethical purposes. Ethical hackers are skilled at techniques used by criminal hackers but use their skills to test security and find vulnerabilities with permission. The document outlines different types of hackers and hacking, how to defend against hacking through strong passwords and updates, and the legal consequences of illegal hacking versus the paid work of ethical hackers.

CISummit 2013: Tom McAndrew, Discover Your Insider Threats through Their Network
This document discusses insider threats and recommendations to address them. It notes that insider threats remain the top counterintelligence challenge, as the most damaging failures in US history were caused by trusted insiders. Insiders are motivated by ideology, money, sex, or blackmail. They operate undetected for years on average before being caught, increasing damage over time. Effective insider threat programs are needed to proactively identify threats before they fully mature. The FBI recommends screening new employees carefully, ongoing security training, anonymous reporting systems, protecting information adequately, monitoring networks, and ensuring security teams have needed tools. Network analytics can help detect insider threats by monitoring activity.

Cyber security lifting the veil of hacking webinar
An APM webinar sponsored by the APM Midlands Branch on 15 March 2022.
Speaker: Fábio Morais
An overview of the people behind major cybercriminal activities, the dark web and how much your data is worth; and finally what basic measures project managers should be putting in place to reduce the cyber-risk profile of their projects.
In today’s data-driven world, data breaches can impact on projects that affect hundreds of millions or even billions of people at a time. Digital transformation has increased the supply of data moving, and data breaches have scaled up with it as attackers exploit the data-dependencies of daily life.
With recent attacks threatening to de-rail high profile projects, it’s vital that the risks are identified and actions implemented, not only to protect project data, but to protect project managers and stakeholders.
Most cybercrime is an attack on information about individuals, corporations, or governments and events can occur in jurisdictions separated by vast distances. The Internet offers criminals multiple hiding places in the real world as well as in the network itself, posing severe problems for law enforcement, since international cooperation is usually required to investigate and attempt to trace down cybercriminals.
But who are these individuals and where exactly does cybercrime take place? What, as project professionals, can we do to protect ourselves?
We look to answer these questions by lifting the veil of hacking and the Dark Web.

Cyberwar attacks can be launched without engaging in physical hostilities and still do
tremendous damage. Countries can use cyberwar attacks to do massive damage to one
another’s financial infrastructures, to disrupt one another’s communication infrastructures,
and to damage the country’s IT infrastructure all as precursors to actual physical hostilities.
Cyberterror
Another nightmare scenario is cyberterror, in which the attacker is a terrorist or group of
terrorists.90 Of course, cyberterrorists can attack information technology resources directly.
They can damage a country’s financial, communication, and utilities infrastructure.91

Hacking Presentation v2 By Raffi
Shawon Raffi is presenting on the topic of hacking. He explains that hacking has negative connotations but can actually be used for positive purposes like security testing and finding vulnerabilities. There are different types of hackers, including black hat hackers who perform criminal acts and white hat hackers who work in cybersecurity. The presentation then covers the history of hacking, definitions, famous hackers, countries with many hackers, and tips for protecting against hackers. It aims to provide an overview of hacking and clear up misconceptions, while emphasizing the importance of ethical hacking for security.
ETHICAL HACKING
This document discusses ethical hacking and defines it as activities done to intrude on someone else's personal information for malicious purposes. It outlines common hacking methods such as identifying targets, gathering information, finding loopholes, and exploiting systems without leaving traces. Reasons hackers hack include stealing credit card or identity information for money or business data. Negative impacts are financial losses from hacks and loss of information. The history and classes of attacks are also summarized.
Cyber Crimes.pptx
Cyber crimes can take several forms:
1) Financial fraud crimes involve altering data to obtain benefits through identity theft, bank fraud, or theft of classified information.
2) Cyberterrorism is the use of computers to intimidate or coerce for political or social goals, such as propaganda promoting violence.
3) Cyberextortion occurs when hackers launch cyberattacks like denial-of-service attacks against websites or systems and demand money to stop.
HACKING
Hacking refers to attempting to gain unauthorized access to computer systems or networks. There are different types of hackers, including white hat hackers who test security systems to help organizations, black hat hackers who access systems maliciously, and gray hat hackers whose activities fall between white and black. Common types of hacking include website, email, network, password, and computer hacking through techniques like sniffing passwords, spoofing addresses, cracking encryption, brute force guessing, and exploiting poor web application coding. Organizations can help prevent hacking by employing ethical hackers to test security, not exposing passwords to untrusted sites, closing internet access when not in use, and having basic internet knowledge.
Cyber Wars.pptx
Cyberwar is a form of conflict conducted in the digital realm, where nations, organizations, or individuals use cyberattacks and cyber espionage to achieve strategic goals or gain an advantage over their adversaries. Here's a detailed description of the topic:
1. **Definition**: Cyberwar refers to the use of computer-based techniques and tactics to disrupt, damage, or gain unauthorized access to computer systems, networks, and critical infrastructure, often with the intent to exert influence, espionage, or conduct acts of aggression against an adversary.
2. **Goals and Objectives**:
- **Espionage**: One primary objective of cyberwarfare is to gather intelligence by infiltrating the computer networks of other nations, organizations, or individuals.
- **Disruption**: Cyberwarfare can be used to disrupt critical infrastructure, such as power grids, transportation systems, or financial institutions, causing chaos and economic damage.
- **Destruction**: In some cases, cyberattacks may aim to destroy data, systems, or capabilities, causing long-term damage.
- **Psychological Operations**: Cyberwarfare can be used for psychological operations (PsyOps) to manipulate public opinion or create fear and uncertainty.
3. **Methods**:
- **Malware**: The use of malicious software like viruses, worms, Trojans, and ransomware to compromise systems.
- **Phishing**: Deceptive emails or websites that trick individuals into revealing sensitive information like passwords.
- **Denial of Service (DoS) and Distributed Denial of Service (DDoS)** attacks: Overwhelming a target's network or website to render it inaccessible.
- **Advanced Persistent Threats (APTs)**: Long-term, targeted attacks aimed at stealing information or controlling systems.
- **Zero-Day Exploits**: Exploiting vulnerabilities in software or hardware that are not yet known to the vendor.
4. **Attribution Challenges**: Determining the source of cyberattacks can be difficult due to the use of proxy servers, false flags, or the involvement of non-state actors.
5. **International Laws and Norms**: The legal framework for cyberwar is still evolving. Nations are working to establish rules and norms governing state behavior in cyberspace.
6. **Escalation and Deterrence**: The use of cyberweapons raises concerns about escalation and deterrence. The lack of clear boundaries in cyberspace can lead to unintended consequences.
7. **Notable Examples**:

Hacking and identity theft are growing problems as more information is stored and transmitted digitally. Hacking ranges from minor pranks to serious crimes like theft of personal information or disabling of critical systems. Early hackers were motivated by intellectual challenge, but now criminal gangs conduct hacking for financial gain. Identity theft involves stealing personal information like social security numbers to commit fraud. Criminals use phishing emails and websites to trick victims into revealing private details. Biometrics like fingerprints offer more secure identification than cards or passwords that can be stolen. Laws aim to prevent digital crimes while protecting free speech rights of "hacktivists".

The document then discusses the international and cross-border nature of cybercrime, defines different types of cybercrimes such as hacking, identity theft, and cyberbullying, and examines the motivations and impacts of cybercriminals.
Cybercrime: A Seminar Report
Cyber crime is a growing problem as more activities move online. There are many types of cyber crimes, including hacking, identity theft, and cyberbullying. Cyber criminals operate in organized networks similar to businesses, with different roles like leaders, engineers, and money mules. They are motivated by profit and use various technical methods and resources to attack networks and systems. Governments struggle to combat cyber crime due to its global and anonymous nature online.
"Cyber crime", or computer-oriented crime..!!
Cybercrime involves using computers or networks to commit crimes. This document discusses several types of cybercrimes such as financial fraud, cyberterrorism, cyber extortion, cyber warfare, and using computers as targets. It provides examples of documented cybercrime cases and discusses efforts by governments and law enforcement to counter cybercrime. It also covers computer security and cybersecurity measures to protect systems from theft, damage, or service disruption.
Cyber espionage
Cyber espionage is a form of cyber attack where classified data or intellectual property is stolen to gain a competitive advantage. Some of the earliest cases involved hackers targeting US military bases in the 1980s. Nation states, criminal groups, and terrorists now use tools like malware and wireless surveillance to spy on governments and companies. Notable cases include attacks on Google and energy companies, as well as espionage targeting presidential campaigns and fighter jet projects. Protecting against cyber espionage requires strategies like partnering with security experts, identifying vulnerabilities, and rapidly detecting and responding to potential compromises.
Course on Ehtical Hacking - Introduction
The document provides a history of hacking from the 1960s to the late 1990s. It describes how the original meaning of "hack" referred to clever programming at MIT. It discusses early phone phreaks and the discovery that a toy whistle could be used to hack phone systems. Over time, hacking groups formed, magazines were published, and laws were passed to criminalize hacking activities. Famous hackers like Kevin Mitnick were arrested. By the late 1990s, hacking became more serious and targeted major websites and banks. The document then defines terms like hackers, crackers, and ethical hackers who perform authorized security assessments.
News Bytes
The document discusses several cybersecurity issues: KRACK, a vulnerability that allows hackers to decrypt WiFi network data without knowing the password; Bad Rabbit ransomware that infected over 200 organizations in Europe; malware that exploits the Dynamic Data Exchange feature in Microsoft Office to distribute ransomware and banking trojans; ready-made ATM malware that is being sold online for $5,000 to steal cash from ATMs; and a cross-site scripting vulnerability found in the KeystoneJS web framework. It provides details on how these attacks work and recommendations for preventing or mitigating the risks.
Network security threats ahmed s. gifel
1. Huge data breaches of personal information from major companies will continue to be a threat, as seen in the 2017 Equifax breach of 143 million Americans. Deep learning models may be targeted at data brokers to steal browsing habits.
2. The weaponization of deep learning means hackers can use AI to craft highly targeted phishing attacks and design malware that evades security systems.
3. Cyber-physical attacks on infrastructure like electrical grids and transportation could cause disruption or be used for ransomware threats. Vulnerabilities in older systems may also be found.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
