The cyber kill chain is intended to defend against sophisticated cyberattacks, also known as advanced persistent threats (APTs), wherein adversaries spend significant time surveilling and planning an attack. Most commonly these attacks involve a combination of malware, ransomware, Trojans, spoofing and social engineering techniques to carry out their plan.
Phase 1: ReconnaissanceDuring the Reconnaissance phase, a malicious actor identifies a target and explores vulnerabilities and weaknesses that can be exploited within the network. As part of this process, the attacker may harvest login credentials or gather other information, such as email addresses, user IDs, physical locations, software applications and operating system details, all of which may be useful in phishing or spoofing attacks. Generally speaking, the more information the attacker is able to gather during the Reconnaissance phase, the more sophisticated and convincing the attack will be and, hence, the higher the likelihood of success.
Generally speaking, the earlier the organization can stop the threat within the cyber attack lifecycle, the less risk the organization will assume. Attacks that reach the Command and Control phase typically require far more advanced remediation efforts, including in-depth sweeps of the network and endpoints to determine the scale and depth of the attack. As such, organizations should take steps to identify and neutralize threats as early in the lifecycle as possible in order to minimize both the risk of an attack and the cost of resolving an event.
Another potential shortcoming of the kill chain is that it is limited in terms of the types of attacks that can be detected. For example, the original framework is not able to detect insider threats, which is among the most serious risks to an organization and one of the attack types that has the highest rates of success. Attacks that leverage compromised credentials by unauthorized parties also cannot be detected within the original kill chain framework.
Web-based attacks may also go undetected by the cyber kill chain framework. Examples of such attacks include Cross Site Scripting (XSS), SQL Injection, DoS/DDoS and some Zero Day Exploits. The massive 2017 Equifax breach, which occurred in part because of a compromised software patch, is a high-profile example of a web attack that went undetected due to insufficient security.
Assaults and manipulation of computer networks are rampant around the world. One of the biggest challenges is fitting the ever-increasing amount of information into a whole plan or framework to develop the right strategies to thwart these attacks. This book clears the confusion by outlining the approaches that work, the tools that work, and resources needed to apply them.
Governments, criminals, companies, and individuals are all operating in a world without boundaries, where the laws, customs, and norms previously established over centuries are only beginning to take shape. Meanwhile computer espionage continues to grow in both frequency and impact. This book will help you mount a robust offense or a strategically sound defense against attacks and exploitation. For a clear roadmap to better network security, Network Attacks and Exploitation is your complete and practical guide.
The cyber kill chain is a series of steps that trace stages of a cyberattack from the early reconnaissance stages to the exfiltration of data. The kill chain helps us understand and combat ransomware, security breaches, and advanced persistent attacks (APTs).
With the above breakdown, the kill chain is structured to reveal the active state of a data breach. Each stage of the kill chain requires specific instrumentation to detect cyber attacks, and Varonis has out-of-the-box threat models to detect those attacks at every stage of the kill chain.
A cyber attack is any attempt to gain unauthorized access to a computer, computing system or computer network with the intent to cause damage. Cyber attacks aim to disable, disrupt, destroy or control computer systems or to alter, block, delete, manipulate or steal the data held within these systems.
People who carry out cyber attacks are generally regarded as cybercriminals. Often referred to as bad actors, threat actors and hackers, they include individuals who act alone, drawing on their computer skills to design and execute malicious attacks. They can also belong to a criminal syndicate, working with other threat actors to find weaknesses or problems in the computer systems -- called vulnerabilities -- that they can exploit for criminal gain.
Government-sponsored groups of computer experts also launch cyber attacks. They're identified as nation-state attackers, and they have been accused of attacking the information technology (IT) infrastructure of other governments, as well as nongovernment entities, such as businesses, nonprofits and utilities.
Financial gain. Cybercriminals launch most cyber attacks, especially those against commercial entities, for financial gain. These attacks often aim to steal sensitive data, such as customer credit card numbers or employee personal information, which the cybercriminals then use to access money or goods using the victims' identities.
Other financially motivated attacks are designed to disable computer systems, with cybercriminals locking computers so owners and authorized users cannot access the applications or data they need; attackers then demand that the targeted organizations pay them ransoms to unlock the computer systems.
Disruption and revenge. Bad actors also launch attacks specifically to sow chaos, confusion, discontent, frustration or mistrust. They could be taking such action as a way to get revenge for acts taken against them. They could be aiming to publicly embarrass the attacked entities or to damage the organizations' reputations. These attacks are often directed at government entities but can also hit commercial entities or nonprofit organizations.
Nation-state attackers are behind some of these types of attacks. Others, called hacktivists, might launch these types of attacks as a form of protest against the targeted entity; a secretive decentralized group of internationalist activists known as Anonymous is the most well known of such groups.
Cyberwarfare. Governments around the world are also involved in cyber attacks, with many national governments acknowledging or suspected of designing and executing attacks against other countries as part of ongoing political, economic and social disputes. These types of attacks are classified as cyberwarfare.
Cyber attacks often happen in stages, starting with hackers surveying or scanning for vulnerabilities or access points, initiating the initial compromise and then executing the full attack -- whether it's stealing valuable data, disabling the computer systems or both.
Several months before that, the massive SolarWinds attack breached U.S. federal agencies, infrastructure and private corporations in what is believed to be among the worst cyberespionage attacks inflicted on the U.S. On Dec. 13, 2020, Austin-based IT management software company SolarWinds was hit by a supply chain attack that compromised updates for its Orion software platform. As part of this attack, threat actors inserted their own malware, now known as Sunburst or Solorigate, into the updates, which were distributed to many SolarWinds customers.
The first confirmed victim of this backdoor was cybersecurity firm FireEye, which disclosed on Dec. 8 that it was breached by suspected nation-state hackers. It was soon revealed that SolarWinds attacks affected other organizations, including tech giants Microsoft and VMware, as well as many U.S. government agencies. Investigations showed that the hackers -- believed to be sponsored by the Russian government -- had been infiltrating targeted systems undetected since March 2020.
The types of cyber attacks, as well as their sophistication, also grew during the first two decades of the 21st century -- particularly during the COVID pandemic when, starting in early 2020, organizations enabled remote work en masse and exposed a host of potential attack vectors in the process.
Hackers also adopted more sophisticated technologies throughout the first decades of the 21st century, using machine learning and artificial intelligence, as well as bots and other robotic tools, to increase the velocity and volume of their attacks.
Life today has become far more comfortable because of various digital devices and the internet to support them. There is a flip side to everything good, and that also applies to the digital world today. The internet has brought in a positive change in our lives today, but with that, there is also an enormous challenge in protecting your data. This gives rise to cyber attacks. In this article, we will discuss the different types of cyber attacks and how they can be prevented.
Before heading to the different types of cyber attacks, we will first walk you through a cyber attack. When there is an unauthorized system/network access by a third party, we term it as a cyber attack. The person who carries out a cyberattack is termed as a hacker/attacker.
Cyber-attacks have several negative effects. When an attack is carried out, it can lead to data breaches, resulting in data loss or data manipulation. Organizations incur financial losses, customer trust gets hampered, and there is reputational damage. To put a curb on cyberattacks, we implement cybersecurity. Cybersecurity is the method of safeguarding networks, computer systems, and their components from unauthorized digital access.
There are many varieties of cyber attacks that happen in the world today. If we know the various types of cyberattacks, it becomes easier for us to protect our networks and systems against them. Here, we will closely examine the top ten cyber-attacks that can affect an individual, or a large business, depending on the scale. 2b1af7f3a8
