The 7 Stages of Hacking

Hacking can be likened to ‘Piracy’, if at all it isn’t just another name for piracy, in and out of itself. It is a process with a lot of unwritten rules that hackers abide by to land their prey and feast on their harvest.

It is also interesting to know that this framework followed by hackers who carry out hacks is known as the Lockheed Martin Cyber Kill Chain which ironically enough serves as a methodology that is designed to recognize and stop cyber-attacks.

Finding out about a prospective target is the first step in the process, which leads to data theft at the conclusion. What steps do hackers take to compromise a system, then?

The Kill Chain comprises of seven steps.

Hackers Gather and Study Information

Scoping out the target is the first step of a cyberattack called reconnaissance. This often entails gathering data that is openly accessible about a possible target, such as social media usernames, email addresses, and public records.

If they are interested in a particular person, they might find this information through data leaks or by carrying out the menial tasks.

In the latter scenario, they might use more advanced techniques like a Bluetooth attack or network interception, sometimes known as a Man-in-the-Middle (MITM) attack. While the latter can only be accomplished on-site by intercepting the victim’s Wi-Fi, the former requires the hacker to be physically present near the target.

The ultimate objective is to discover as much as possible about the targets, including their operating systems, the devices they use, and the services they utilize. They may be able to identify weaknesses with the knowledge they learn here.

The Equipment Required for Attacks is Obtained by Hackers

Within the Cyber Kill Chain, this phase is referred to as “weaponization.” After gathering the necessary resources for the cyberattack, hackers arm themselves with knowledge about their possible targets. For instance, they might produce malware and conceal it in files that their victim is likely to download.

You could compare this phase to going fishing. This is where our reference to Piracy comes into play; for those familiar with the term in reference to criminals on sea. The equipment you’ll need to bring along for freshwater lake fishing will be different from the equipment you’ll need for ocean fishing. Most likely, you would use a different boat as well.

The 7 Stages of Hacking

Hackers set up traps by casting a wide net

In the Kill Chain, this phase is referred to as “delivery.” At essence, the bad guys are invited into the fortress in this step, which involves fooling the target into installing the malware.

Hackers frequently carry out this activity by disseminating emails that include malicious files.

The malware may also be delivered via photos, as was the case when hackers used images from the James Webb telescope to transmit malware. Another typical method used by hackers to spread malware is SQL injection.

The objective is to convince the target to download malware onto their device in any way possible. From this point on, the virus takes control, mechanically extracting and injecting itself into the system.

A System Vulnerability is exploited by the Malware

As soon as it is on the target’s computer, the malware takes control. The malware may automatically extract and operate on the victim’s device if certain background events, such USB or Media Autoplay, are triggered. “Extraction” is the name of this stage.

Malware acts as intended by its programming

In this stage, the malware typically discreetly installs itself in the background without the victim’s knowledge once it has gained access to the machine (or computer network).

The system then starts looking for flaws that could be exploited to give the hacker elevated administrative rights.

A Command-and-Control System is also established between the malware and the hacker. The hacker can use this technique to get regular status reports on the hack’s development.

Consider the Command-and-Control System as an intelligence officer who doubles as a spy for another unit to put it into perspective. Due to their position, the spy has access to critical information. They are also prepared to gather and send stolen intelligence covertly thanks to this status.

The 7 Stages of Hacking

The Spy System Takes Control and Grows                                                                                  

To construct its Command-and-Control System, which is also the name of the sixth stage in the Kill Chain, the malware does a number of actions at this stage. It usually keeps checking for weaknesses in the system. In addition, if the victim learns where the entry point is, it may construct backdoors that hackers can use to access the system.

Additionally, in order to infect additional devices connected to the compromised devices, the system searches for additional devices in that network. Comparable to when the common cold strikes the entire office. Anyone can forget exactly who started it if enough time has passed.

Take, destroy, and flee

In the real hacking procedure, sensitive data like login credentials, credit card numbers, or files holding trade secrets are taken in the last stage, when the cybercriminal has enhanced control over the victim’s system.

The system’s files could also be destroyed by a hacker, which is harmful in particular if the victim doesn’t have a backup of the data that was taken and lost.

Data Warehousing and Data Management Cost Optimization

In this article, we will discuss the key aspects of data warehousing and management cost optimization and best practices established through studies.

Data warehousing and management is a crucial aspect of any organization, as it helps to store, manage, and analyze vast amounts of data generated every day. With the exponential growth of data, it has become imperative to implement cost-effective solutions for data warehousing and management.

Understanding Data Warehousing and Management

Data warehousing is a process of collecting, storing, and analyzing large amounts of data from multiple sources to support business decision-making. The data stored in the warehouse is organized and optimized to allow for fast querying and analysis. On the other hand, data management involves the processes and policies used to ensure the data stored in the warehouse is accurate, consistent, and accessible.

Why is Cost Optimization Important?

Data warehousing and management costs can add up quickly, making it essential to optimize costs. Implementing cost-optimization strategies not only reduces financial burden but also ensures that the data warehousing and management system remains efficient and effective.

Cost optimization is important for data warehousing and management for several reasons:

Financial Benefits: Data warehousing and management can be expensive, and cost optimization strategies can help reduce these costs, thereby increasing the overall financial efficiency of the organization.

Improved Performance: Cost optimization strategies, such as data compression, data archiving, and data indexing, can help improve the performance of the data warehousing and management system, thereby reducing the time and effort required to manage the data.

Established Cost Optimization Strategies

Scalable Infrastructure: It is important to implement a scalable infrastructure that can handle increasing amounts of data without incurring significant costs. This can be achieved through cloud computing solutions or using a combination of on-premises and cloud-based solutions.

Data Compression: Data compression can significantly reduce the amount of storage required for data, thus reducing costs. There are various compression techniques available, including lossless and lossy compression, which can be used depending on the type of data being stored.

Data Archiving: Data archiving is the process of moving data that is no longer actively used to cheaper storage options. This helps to reduce the cost of storing data while ensuring that the data remains accessible.

Data de-duplication identifies and removes duplicate data from the warehouse. This helps to reduce storage costs and improve the overall performance of the data warehousing system. Data de-duplication is a cost optimization strategy for data warehousing and management that focuses on identifying and removing duplicate data from the warehouse. This is important for several reasons:

Reduced Storage Costs: Duplicate data takes up valuable storage space, which can be expensive. By removing duplicates, the storage requirements for the data warehouse can be reduced, thereby reducing storage costs.

Improved Data Quality: Duplicate data can lead to confusion and errors in decision-making, as it may not be clear which version of the data is accurate. By removing duplicates, the quality of the data stored in the warehouse can be improved, which can lead to better decision-making.

Improved Performance: The presence of duplicate data can slow down the performance of the data warehousing system, as it takes longer to search for and retrieve the desired data. By removing duplicates, the performance of the data warehousing system can be improved, reducing the time and effort required to manage the data.

Increased Security: Duplicate data can pose a security risk, as it may contain sensitive information that can be accessed by unauthorized individuals. By removing duplicates, the security of the data stored in the warehouse can be increased.

Overall, data de-duplication is an important cost optimization strategy for data warehousing and management, as it helps to reduce storage costs, improve data quality, improve performance, and increase security. It is important to implement an effective data de-duplication solution to ensure the success of this strategy.

Data Partitioning: Data partitioning involves dividing the data into smaller, manageable chunks, making it easier to manage and analyze. This helps to reduce the cost of storing and processing large amounts of data.

Data Indexing: Data indexing is the process of creating an index of the data stored in the warehouse to allow for fast querying and analysis. This helps to improve the performance of the data warehousing system while reducing costs.

Automation: Automating data warehousing and management processes can significantly reduce the cost and effort required to manage the data. This includes automating data extraction, transformation, loading, and backup processes.

Conclusion

In conclusion, data warehousing and management cost optimization is a crucial aspect of any organization. Implementing cost-optimization strategies, such as scalable infrastructure, data compression, data archiving, data de-duplication, data partitioning, data indexing, and automation, can significantly reduce the cost of data warehousing and management while ensuring that the system remains efficient and effective.
