skills
Ethical hackers need to have a good mastery of different kinds of skills if they need to be at the top of their game. The skill sets required in each job vary from one to the other. Bug bounty hunters need to have deep knowledge of the working of web or mobile applications depending on which type they work with. Security analysts will need to have some knowledge of statistics coupled with cybersecurity.

While the differences are there between each career, the basics stay the same for all of them. Here are the top 5 skill sets needed by every kind of ethical hacker.

1. Basic Programming
Just like everyone thinks that hackers are experts at programming, programming is one of the prerequisites needed by every ethical hacker. But there is a slight difference in the stereotype that people have about hackers. Hackers don’t need to have an in-and-out knowledge of a single programming language.

It is better to know the basics of all languages than to exhaust yourself with a single language. If you know multiple languages, it’ll help you work with multiple target devices and a versatile approach to your work. Sticking with a single language limits the vulnerabilities an ethical hacker can find. Whereas knowing the basics of multiple languages can allow you to grasp things further adding to your skills. That is also easier than starting a new language from scratch for each project that requires any language other than the one you’ve become an expert in.

2. Computer Networking
In a world that has become extremely dependent on being connected, businesses need to be digitalised in one form or the other. Maintaining an isolated system.

isn’t possible which means computers and other devices need to be connected to a network. This gives rise to a whole new set of vulnerabilities associated with the connected network. Having knowledge of how computer networks work helps hackers get into impenetrable systems. Understanding the usage of DHCP, NAT and Subnetting among other types of networks allows a hacker to find out various weak points in the network and how to exploit them. In scenarios where there are no vulnerabilities in the target device, exploiting network vulnerabilities is the only way to get in sometimes.

3. Linux
Almost every project that an ethical hacker is involved with deals with servers in one way or the other. Most of these servers are run on the Linux operating system.

To find vulnerabilities and play around with the server to find vulnerabilities, an ethical hacker needs to have a good base in the working of Linux. Apart from having experience dabbling with the interface of Linux, ethical hackers need to have some experience working with the kernel and executing commands. There is no use if you can’t understand what’s happening in the server once you get inside the server.

4. DBMS
Every company stores at least some sort of data in a database. While the type of data stored in each company might differ, the medium of storage remains the same. If a cybercriminal gains access to a database, the impact will be felt in a huge manner.

An ethical hacker needs to know about the different types of Database Management Systems, DBMS short. Since these are the tools used in creating databases, ethical hackers need to be well-versed in these systems. Only then can the vulnerabilities in these databases be patched. Since the data stored by companies is one of the biggest targets of cybercriminals, it is a huge priority to ensure their safety. Ethical hackers need to ensure that they have enough knowledge of DBMS to ensure their career prospects in this competitive world.

5. Computer Knowledge
Last but not least, every ethical hacker needs to know the basics of computer knowledge. For what is a hacker who is supposed to break into someone else’s computer if he/she doesn’t know how to use a computer? Apart from knowing about the software running inside a computer, ethical hackers also need to know about the hardware that stays under the hood.

While the knowledge of software might seem obvious, the knowledge of hardware and its layout in a computer can also come useful in certain situations. In scenarios where an ethical hacker gains access to the system, all the hardware knowledge will come in handy. In such situations, it’s easier to physically insert the malware than upload it onto the system by digital means. This can be done only with knowledge of the internal hardware layout.

6. Practice
Apart from obtaining all these skills, you need to practice them frequently. Knowing these but not using them often can make you go outdated. As the saying goes, “Practice makes a man perfect”.

Ethical Hacking

Ethical hacking is all about finding computer weaknesses and getting the issue fixed.

Ethical Hacking Definition
Ethical hacking identifies vulnerabilities in a system and systematically resolves them before it gets worse. The hacking process involves the word consent, which discerns from other hacking techniques.

Ethical hacking is all about analyzing the enterprise’s security plan by a team of professionals, who are also known as” White hat hackers”. Their main aim is to pe*****te the system to fix the vulnerabilities with prior permission from the client/organization and present a scorecard indicating the chances of risk. Public and private firms and banks usually hire ethical hackers to avoid cybercrimes.

Importance of Ethical Hacking
Regardless of the organization type, you may have to deal with web applications for day-to-day business activities. Considering the organization’s perspective of safeguarding valuable assets/ data, the apt choice is to go for ethical hacking.

Despite the ever-growing demand for ethical hackers globally, many individuals are still worried about security threats.

Here are a few reasons why ethical hacking is worth considering:

Though the prime purpose of implementing ethical hacking is to prevent sensitive information from into prey’s hands, it also improves digital network security through real-world testing.
Ethical hacking helps you to identify potential entry points from hackers and fix it a timely.
Considering an employment perspective, ethical hacking helps to upskill your knowledge to get into various job roles such as quality assurance tester, software developer, risk management, etc.
In addition to protecting the organization’s valuable information, it also prevents cyber-terrorism, ensuring the nation’s safety.
Ethical hackers are the major strength of the organization. They work with quality analysts and perform quick security tests under all conditions to check whether the software functions aptly.
Next in this Ethical Hacking tutorial, let’s understand what are the skills required to become an Ethical Hacker.

Ransomware attacks in April 2020

4. Energias de Portugal ransomware attack
In April, it was reported that Portuguese energy giant Energias de Portugal (EDP) had fallen victim to an attack. Cybercriminals using the Ragnar Locker ransomware encrypted the company’s systems and demanded a ransom of nearly $10 million.

The attackers claimed to have stolen over 10TB of sensitive company data, which they threatened to leak unless the ransom was paid. The hackers posted screengrabs of some sensitive data on a leak site that purported to show proof of possession. The data supposedly included confidential information about billing, contracts, transactions, clients, and partners.

EDP confirmed that an attack had taken place but said there was no evidence that sensitive customer data had been compromised. However, on the basis that theft of customer data could come to light in the future, the company offered customers a year of Experian identity protection at no cost.

Ransomware attacks in January 2020

1. Travelex ransomware attack
Hackers started the year with an attack on foreign exchange company Travelex, forcing the company to turn off all computer systems and rely on pen and paper. The company had to take down its websites in 30 countries as a result.

A ransomware gang called Sodinokibi (also known as REvil) was behind the attack, demanding $6 million from Travelex. The gang claimed to have accessed the company’s computer network six months previously, enabling it to download 5GB of sensitive customer data – including dates of birth and credit card numbers. The gang said that if Travelex paid the ransom, they would delete the data but if not, the ransom would double every two days. After seven days, they said they would sell the data to other cybercriminals.

Travelex reportedly paid the gang $2.3 million in Bitcoin and restored its online systems after two weeks offline. In August 2020, the company announced it was going into administration (the UK equivalent of going into Chapter 11), blaming a combination of the ransomware attack and the impact of the Covid-19 pandemic.

Top 10 Hackers in the world

The top hackers in the world come from different backgrounds and geographical locations with a shared common theme of having an early passion for technology. Given that the Cobalt Core is our own “hacker marketplace” (i.e. a highly vetted global community of top pentesting talent), we thought it was worth giving a nod to the most famous names in the game, who paved the way and tested the boundaries for future hackers to come.

As early technology adopters, many individuals on the list of top 10 famous hackers include those who tested the technological, legal, and ethical questions that encompass the world of cybersecurity and hacking. Their actions gave rise to regulations and frameworks that transformed the world of cybersecurity and hacking.

*For the purposes of this list, let’s define ‘most famous as the top headline-grabbing individuals who attracted widespread notoriety and have remained in the public consciousness for a sustained period. It’s also worth noting that we are only evaluating named hackers (for instance, we can’t evaluate anyone behind the SolarWinds breach because they remain anonymous).

10. Aaron Swartz
Aaron Swartz famously helped start the popular online social network Reddit and created a cascade of attention throughout his time as a hacktivist. In 2011, the government arrested and charged Swartz with hacking into MIT’s network to download a massive cache of JSTOR academic data. These charges eventually evolved into two federal counts of wire fraud and nearly a dozen violations of the Computer Fraud and Abuse Act with a maximum penalty of a million dollars and 35 years in prison.

Through the plea bargain process, which Swartz declined to participate in, he tragically committed su***de. A couple of years after his death the Internet Hall of Fame inducted Swartz for his work founding online groups such as Demand Progress and their campaign against the Online Privacy Act.
