“Hackers and Hacking Attacks”- Magician and Their Magic Wand For ISSN XXXX XXXX © 2019 IJESC Research Article Volume 9 Issue No. 5 “Hackers and Hacking Attacks”- Magician and Their Magic Wand for Security Breech Manish JitendrabhaiVankani Department of SOE – MCA RK University, Rajkot, Gujarat, India Abstract: In Modern era, each and every data is available online. Any person across the world can access that data very easily. Some people use this data to gain the information while other people use this data to fulfil their malicious intent. There are lots of methods used for protection of data but the hacker is far more intelligent to hack the security. There are main two types of hackers that are different from each other on the basis of their purpose. The one who tries to break the computer system’s security with malicious intention is known as bad hacker or cracker. The other one who has good purpose is known as ethical hacker because he uses his skills to provide security to sensitive data of big firms.In this paper I describe the types of Hackers,Ethical hacking,typesof Hacking attacks and Hacking tools. Keywords: Ethical hackers, Hacking, cracker. I. INTRODUCTION: hardware as well as software. Hacker is a computer dedicated and expert in a programming language, security, and networks. As the computer technology enhances, it has its darker side He is kind of person who loves to gain knowledge ofdifferent also. In modern era the need of the internet is growing rapidly. technologies, details of the computer system and enhances his Enormous amount of data is moving online, therefore, data capability and skills. According to the way of working or security is the key issue. The internet has led to the increase in based on their intensions Hackers can be classified into three the digitization of various processes like banking, online groups: transaction, online money transfer, online sending and receiving of various forms of data, thus increasing the risk of 1. White Hat Hackers: - the data security. At present time large number of companies, A White hat hackers are driven by honourable motivations or organizations, banks, and websites aretargeted by the different agendas. They are also known as ethical Hackers, white hats types of malicious attacks by the hackers. Generally, after are talented computer security users often employed to protect listening to the term hacker we all think of the bad guys who computer networks. Ethical hackers usually have permission are computers experts with malicious intensions, who tries to from the owner of any system they work on. These cyber steal, leak or destroy someone's confidential or precious data security specialists are experts on closing vulnerabilities and without their knowledge. They are the persons with very high dealing with attacks from black hat hackers. Some white hat computer skills who tries to break into someone else’s security hackers are academic hackers. These are computer skilled for gaining access to their personal information, but all the users who are less interested in protecting systems and more times it is not like that. To overcome the risk of being hacked interested in creating clever programs and interfaces. Their by the hackers we have Ethical Hackers in industry, who are motivation is to improve a system through modifications and also computer experts just like the hackers but with good additions. Academic hackers can be casual hobbyist. intensions or bounded by some set of rule and regulations by the various organizations. These are the persons who try to 2.Black Hat Hackers: - protect the online moving data by the different attacks of the A Black Hat Hacker also known as a “Cracker” who wilfully hackers and keeping it safewith the owner. commits thefton other user’s networks. The term “black hat” is a way to describe their malicious motivation. Black hat hackers What is Hacking? are gifted with great skills but they are unethical computer Hacking is the method of searching the weak links or users who are motivated by money, fame or criminal purposes. loopholes in the computer systems or the networks and They may steal data to sell it or attempt to extort money from exploiting it to gain unauthorized access to data or to change system owners. They are bad guys of hacking world. They are the characteristics of the target computer systems or the renowned for Identity theft, worms creations, DDOS attack, networks. Hacking describes the modification in the computer etc. hardware, software or the networks to fulfil certain goals which are not aligned with the user goals. In contrast, it is also 3.Grey Hat Hackers: - called breaking intosomeone's security and stealing their A Grey Hat Hacker is a computer hacker or security expert private or confidential data such as phone numbers, credit card who sometimes break the laws but does not have any bad details,addresses, online banking passwords etc. intentions like the black hat hackers. The term Grey Hat is come from the Black Hat and the White Hat as the white hat Hackers: - hackers search the vulnerabilities in the computer system or The term Hacker in popular media is used to describe someone the networks and does not tells anybody until it is being who breaks in to someone else's security using bugs and corrected, while on the other hand the black hat hackers exploits or use his expert knowledge to act productively or illegally exploits the computer system or network to find maliciously. Hackers are the computer specialists in both International Journal of Engineering Science and Computing, May 2019 22095 http://ijesc.org/ vulnerabilities and tells others how to do so whereas the grey Man in the Middle Attack: - hat hacker neither illegally exploits it nor tells anybody how to do so. They enjoy disassembling and altering their own The man in the middle attack is the attack in which the attacker computers for pleasure, and they sometimes experiment in tries to enter in between the communication of the two parties minor white-collar hacks such as file sharing and cracking and can access all the data sent and received by them. In this software. They aren’t usually motivated by personal gain. Grey attack, the attacker makes separate connections with the Hat Hackers represents between the white hat hackers who victims and transmits messages between them to make them operate to maintain system security and the black hat hackers believe that they are talking directly to each other over a who operate maliciously to manipulate computer systems. private connection, but in reality the entire conversation is controlled by the attacker. In this type of attack, the attackers II. TYPES OF HACKING ATTACKS: try to intercept by adopting the approach of IP spoofing, DNS server spoofing, etc. Following are few Hacking attacks which big organization or end user face a lot. Phishing attack: - numbers etc. This can be accomplished by sending fake emails Phishing is a By-product of social media. It is a cyber-attack or or creating dummy websites which looks very similar to the say an online fraud in which the hacker attempts to gain some original ones. Phishing scams can also employ phone calls, sensitive and confidential information such as password, login text messages, and social media tools to trick users into information, credit card numbers, email ids, online banking pin providing sensitive information . Denial of Services (DoS) attack: - It is a type of cyberattack network resource unavailable for its end users temporarily or in which the attacker’s aim is to make a machine, website or a for an undefined time duration and disrupting the services of a International Journal of Engineering Science and Computing, May 2019 22096 http://ijesc.org/ host connected to the internet. This attack is generally done by target server or the website is very speedy in several hundred flooding the target website, server or the computer machine of MBPS or GBPS. In a Distributed Denial of Service (DDoS) with a huge number of requests and making it overloaded, attack, the incoming traffic flooding the victim originates from therefore the target is not able to fulfil most or all of the several different sources. This effectively makes it impossible requests. The DoS attacks can remain for days, weeks or even to prevent the attack by blocking a single source. for months. The attacker’s speed of sending fake requests to LFI and RFI attack: two being less sophisticated and therefore easily preventable. Local File Execution (LFI) and Remote File Execution (RFI) Although not taken seriously by the security community, LFI are similar to the immoral Cross Site Scripting (XSS) attacks. and RFI attacks constitute 21 percent of all observed web All of them are types of code injection attack, with the former application attacks. The percentage share of LFI and RFI attacks among other web application attacks Remote File Inclusion (RFI) is a method which allows an running on PHP, RFI should be on every security researcher’s attacker to employ a script to include a remotely hosted file on radar, but sadly it’s not. The severity of an RFI attack can the web server. The susceptibility promoting RFI is largely range from outputting the contents of a file to arbitrary code observed on websites running on PHP. This is because PHP execution. Local File Inclusion (LFI) is very much similar to supports the ability to “include” or “require” additional files RFI.

    Crackers or Malicious Hackers: System crackers attempt to access computing facilities for which they have not been authorized. Cracking a computer's defenses is seen as the ultimate victimless crime. The perception is that nobody is hurt or even endangered by a little stolen machine time. Crackers enjoy the simple challenge of trying to log in, just to see whether it can be done. Most crackers can do their harm without confronting anybody, not even making a sound. In the absence of explicit warnings not to trespass in a system, crackers infer that access is permitted. Others attack for curiosity, personal gain, or self-satisfaction. And still others enjoy causing chaos, loss, or harm. There is no common profile or motivation for these attackers. Classification of Hackers: Hackers can be classified broadly into three different categories: 1. Black Hat Hacker 2. White Hat Hacker 3. Grey Hat Hacker Black Hat Hacker Black-hat Hackers are also known as an Unethical Hacker or a Security Cracker. These people hack the system illegally to steal money or to achieve their own illegal goals. They find banks or other companies with weak security and steal money or credit card information. They can also modify or destroy the data as well. Black hat hacking is illegal. White Hat Hacker White hat Hackers are also known as Ethical Hackers or a Penetration Tester. White hat hackers are the good guys of the hacker world. These people use the same technique used by the black hat hackers. They also hack the system, but they can only hack the system that they have permission to hack in order to test the security of the system.

  • Reporting, and General Mentions Seem to Be in Decline
    CYBER THREAT ANALYSIS Return to Normalcy: False Flags and the Decline of International Hacktivism By Insikt Group® CTA-2019-0821 CYBER THREAT ANALYSIS Groups with the trappings of hacktivism have recently dumped Russian and Iranian state security organization records online, although neither have proclaimed themselves to be hacktivists. In addition, hacktivism has taken a back seat in news reporting, and general mentions seem to be in decline. Insikt Group utilized the Recorded FutureⓇ Platform and reports of historical hacktivism events to analyze the shifting targets and players in the hacktivism space. The target audience of this research includes security practitioners whose enterprises may be targets for hacktivism. Executive Summary Hacktivism often brings to mind a loose collective of individuals globally that band together to achieve a common goal. However, Insikt Group research demonstrates that this is a misleading assumption; the hacktivist landscape has consistently included actors reacting to regional events, and has also involved states operating under the guise of hacktivism to achieve geopolitical goals. In the last 10 years, the number of large-scale, international hacking operations most commonly associated with hacktivism has risen astronomically, only to fall off just as dramatically after 2015 and 2016. This constitutes a return to normalcy, in which hacktivist groups are usually small sets of regional actors targeting specific organizations to protest regional events, or nation-state groups operating under the guise of hacktivism. Attack vectors used by hacktivist groups have remained largely consistent from 2010 to 2019, and tooling has assisted actors to conduct larger-scale attacks. However, company defenses have also become significantly better in the last decade, which has likely contributed to the decline in successful hacktivist operations.

  • Identity Theft Glossary
    Identity Theft Glossary •Account takeover: An account takeover is when a fraudster uses personal information to ​ ​ obtain products and services. Credit card fraud is the most rampant, but skimming and phishing are also common types of account takeovers. •Anti-virus: Anti-virus software runs continuously in the background of a computer and ​ ​ scans for viruses, worms and malware every time the user accesses a website or downloads anything. •Bait and switch: A bait and switch attack is when a hacker buys advertising space on a ​ ​ webpage and then links the advertisement to a page infected with malware. •Black hat hacker: All hackers are capable of compromising computer systems and creating ​ ​ malware, but black hat hackers use these skills to commit cybercrimes. •Blockchain: A blockchain is a string of time-stamped digital records shared between ​ ​ multiple computers. If the data in one block changes, all subsequent blocks in the blockchain reflect the alteration and become invalid. Blockchains help prevent identity theft and fraud by making it difficult to tamper with the data in a block. •Bot: Short for “robot,” a bot is an autonomous program that interacts with computer ​ ​ systems in a way that appears or attempts to appear human. Hackers can use bots to mine for usernames and passwords used to commit identity fraud. •Cookie theft: Cookie theft is when a cybercriminal makes copies of unencrypted session ​ ​ data and then uses that data to impersonate someone else. •Credential cracking: Credential cracking describes the various methods — word lists, ​ ​ guessing and brute-force — cybercriminals use to obtain passwords. Credential cracking threats are why it’s important to create varied and complicated passwords for all accounts.

  • Attackers and Their Tools Who Is Attacking Our Network? in This Presentation We Will Investigate Threat, Vulnerability, and Risk
    Principles of Cyber Security Attackers and Their Tools Who is Attacking Our Network? In this presentation we will investigate Threat, Vulnerability, and Risk . Threat • Is a potential danger to an asset such as data or the network. Vulnerability and Attack Surface • A vulnerability is a weakness in a system or its design that could be exploited by a threat. • Attack surface describes different points where an attacker could get into a system and could get to the data (Example – operating system without security patches) . Exploit • Is a mechanism used to leverage a vulnerability to compromise an asset. • A Remote exploit works over the network. • A Local exploit is when a threat actor has user or administrative access to the end system. Risk • Likelihood that a threat will exploit a vulnerability of an asset and result in an undesirable consequence. © 2016 Cisco and/or its affiliates. All rights reserved.

  • Hackers Gonna Hack: Investigating the Effect of Group Processes and Social Identities Within Online Hacking Communities
    Hackers gonna hack: Investigating the effect of group processes and social identities within online hacking communities Helen Thackray Thesis submitted for the degree of Doctor of Philosophy Bournemouth University October 2018 This copy of the thesis has been supplied on condition that anyone who consults it is understood to recognise that its copyright rests with its author and due acknowledgement must always be made of the use of any material contained in, or derived from, this thesis. 1 2 Hackers gonna hack: Investigating the effect of group processes and social identities within online hacking communities Helen Thackray Abstract Hacking is an ethically and legally ambiguous area, often associated with cybercrime and cyberattacks. This investigation examines the human side of hacking and the merits of understanding this community. This includes group processes regarding: the identification and adoption of a social identity within hacking, and the variations this may cause in behaviour; trust within in the social identity group; the impact of breaches of trust within the community. It is believed that this research could lead to constructive developments for cybersecurity practices and individuals involved with hacking communities by identifying significant or influencing elements of the social identity and group process within these communities. For cybersecurity, the positive influence on individual security approaches after the hacker social identity adoption, and the subsequent in-group or out-group behaviours, could be adapted to improve security in the work place context. For individuals involved in the communities, an increase in the awareness of the potential influences from their adopted social identities and from other members could help those otherwise vulnerable to manipulation, such as new or younger members.

    Wardlow 1 Cassie Wardlow CST 300L December 4, 2012 Remember, Remember the 5th of November Hackers have been around for many centuries. It wasn’t until recently that they started to have a huge impact on society. Of course what they do has changed over the years, but they still all have the same idea. They don’t agree with government and they make sure their opinion is heard. Before the digital age, hackers weren’t really seen as a threat. Now that they can get into highly protected systems, the government is starting to worry. The history of how hackers came about is an interesting, especially how they have formed large groups today, like the famous Anonymous. Big important businesses and corporations may not enjoy hackers, but they are good for society. Hackers want the public to know that certain business are doing something wrong. Hacktivism is described as “the nonviolent use of legal and/or illegal digital tools in pursuit of political ends” (Skelton, 2012). In October of 1989, the first ever hack was done by a group called W.A.N.K. The stance of W.A.N.K was to bring awareness against the nuclear armament. They hacked into government computers, including NASA, and used a worm to change to login screens. This is what appeared on their screens: Image 1 Wardlow 2 Hackers were still around before computers but just doing things a little bit differently. In the 1600s, Guy Fawkes was in protest against religious intolerance. Guy Fawkes and a group of provincial English Catholics planned to assassinate King James I of England and VI of Scotland.

  • A Survey on Ethical Hacking: Issues and Challenges
    ASURVEY ON ETHICAL HACKING:ISSUES AND CHALLENGES APREPRINT Jean-Paul A. Yaacoub, Hassan N. Noura, Ola Salman, Ali Chehab American University of Beirut, Electrical and Computer Engineering Department, Beirut 1107 2020, Lebanon March 30, 2021 ABSTRACT Security attacks are growing in an exponential manner and their impact on existing systems is seriously high and can lead to dangerous consequences. However, in order to reduce the effect of these attacks, penetration tests are highly required, and can be considered as a suitable solution for this task. Therefore, the main focus of this paper is to explain the technical and non-technical steps of penetration tests. The objective of penetration tests is to make existing systems and their corresponding data more secure, efficient and resilient. In other terms, pen testing is a simulated attack with the goal of identifying any exploitable vulnerability or/and a security gap. In fact, any identified exploitable vulnerability will be used to conduct attacks on systems, devices, or personnel. This growing problem should be solved and mitigated to reach better resistance against these attacks. Moreover, the advantages and limitations of penetration tests are also listed. The main issue of penetration tests that it is efficient to detect known vulnerabilities. Therefore, in order to resist unknown vulnerabilities, a new kind of modern penetration tests is required, in addition to reinforcing the use of shadows honeypots. This can also be done by reinforcing the anomaly detection of intrusion detection/prevention system. In fact, security is increased by designing an efficient cooperation between the different security elements and penetration tests.
