, is a powerful tool when properly used. It works at the pixel level because it is a raster based software, and this is why your text in Photoshop can become pixelated.
Use Photoshop for:

1. editing photos to post and print
2. creating banner ads, user interface designs, and video graphics
3.creating icons and images for the web

Illustrator ,It is a vector based software, so it uses lines to work and doesn’t pixelate or lose detail. This vector basis means it is really intended for scalable design elements like brand marks and logos.
use Illustrator for:
1. creating website designs
2. creating images with text
3. creating documents for the web or for print, but not if they’re very large multipage documents.
Conclusion:

You’ll come to find that some people just prefer to use one software over another, but sometimes it’s best to use Photoshop and Illustrator together. Lot of the hotkeys and tools are the same in both the software, understanding the application for each program is important.

see you😀

What is Wireshark?

Wireshark is a network packet analyzer. A network packet analyzer presents captured packet data in as much detail as possible.
You could think of a network packet analyzer as a measuring device for examining what’s happening inside a network cable, just like an electrician uses a voltmeter for examining what’s happening inside an electric cable .

Some intended purposes

Here are some reasons people use Wireshark:

1) Network administrators use it to troubleshoot network problems.
2) Network security engineers use it to examine security problems.
3) QA engineers use it to verify network applications
Developers use it to debug protocol implementations
People use it to learn network protocol internals.

What Wireshark is not

1) Wireshark isn’t an intrusion detection system. It will not warn you when someone does strange things on your network that he/she isn’t allowed to do. However, if strange things happen, Wireshark might help you figure out what is really going on.

2) Wireshark will not manipulate things on the network, it will only “measure” things from it. Wireshark doesn’t send packets on the network or do other active things (except domain name resolution, but that can be disabled).

What is a backdoor?

A refers to any method by which authorized and unauthorized users are able to get around normal security measures and gain high level user access (aka root access) on a computer system, network, or software application.

How do backdoors work?

backdoor comes as a result of malware or by an intentional manufacturing (hardware or software) decision.

classes of backdoor .

1) Backdoor malware.
Backdoor malware is generally classified as a Trojan. A Trojan is a malicious computer program pretending to be something it's not for the purposes of delivering malware, stealing data, or opening up a backdoor on your system. Much like the Trojan horse .

2) Built-in or proprietary backdoors
Built-in or proprietary backdoors are put in place by the hardware and software makers themselves. Unlike backdoor malware, built-in backdoors aren't necessarily conceived with some criminal purpose in mind. More often than not, built-in backdoors exist as artifacts of the software creation process.

Are backdoors and exploits the same?

👽Exploits are accidental software vulnerabilities used to gain access to your computer and, potentially, deploy some sort of malware….

👹Backdoors, on the other hand, are deliberately put in place by manufacturers or cybercriminals to get into and out of a system at will.”

What can hackers do with a backdoor?
Hackers can use a backdoor to install all manner of malware on your computer.

1) is a type of malware that, once deployed on your system, collects information about you, the sites you visit on the Internet, the things you download, the files you open, usernames, passwords, and anything else of value.

2) is a type of malware designed to encrypt your files and lock down your computer. In order to get back those precious photos, documents, etc. (or whatever file type the attackers choose to target) you have to pay the attackers via some form of , usually .

3) malware is designed to use your system's resources to mine cryptocurrency. In short, every time someone exchanges cryptocurrency the transaction is recorded on an encrypted virtual ledger known as the blockchain. is the process of validating these online transactions in exchange for more cryptocurrency and it takes an enormous amount of computing power.

How can I protect against backdoors?

1) your default .
The hardworking people in your company's IT department never intended for your actual password to be "guest" or "12345." If you leave that default password in place, you've unwittingly created a backdoor. Change it as soon as possible and enable multi-factor authentication.

2) network activity.
Any weird data spikes could mean someone is using a backdoor on your system. To stop this, use firewalls to track inbound and outbound activity from the various applications installed on your computer.

3) applications and plugins carefully.
As we've covered, cybercriminals like to hide backdoors inside of seemingly benign free apps and plugins. The best defense here is to make sure whatever apps and plugins you choose come from a reputable source.

4) a good solution.
Any good -malware solution should be able to stop from deploying the and rootkits used to open up those pesky backdoors.

Conclusion
Good news bad news. The bad news is that it's difficult to identify and protect yourself against built-in backdoors. More often than not, the manufacturers don't even know the backdoor is there. The good news is that there are things you can do to protect yourself from the other kinds of backdoors.

Different Types Of Hackers – And What They Mean

1) White Hat Hackers

White hat hackers are types of hackers who’re professionals with expertise in cybersecurity. They are authorized or certified to hack the systems. These White Hat Hackers work for governments or organizations by getting into the system.

Motives & Aims:

The goals of these types of hackers are helping businesses and an appetite for detecting gaps in networks’ security.They help enterprises create defenses, detect vulnerabilities, and solve them before other cyber-criminals can find them.

2) Black Hat Hackers

Black hat hackers are also knowledgeable computer experts but with the wrong intention. They attack other systems to get access to systems where they do not have authorized entry.

Motives & Aims:

To hack into organizations’ networks and steal bank data, funds or sensitive information. Normally, they use the stolen resources to profit themselves, sell them on the black market or harass their target company.

3) Gray Hat Hackers

The intention behind the hacking is considered while categorizing the hacker. The Gray hat hacker falls in between the black hat hackers and white hat hackers. They are not certified, hackers. These types of hackers work with either good or bad intentions.

Motives & Aims: The difference is, they don’t want to rob people nor want to help people in particular. Rather, they enjoy experimenting with systems to find loopholes, crack defenses, and generally find a fun hacking experience.

4) Script Kiddies

It is a known fact that half knowledge is always dangerous. The Script Kiddies are amateurs types of hackers in the field of hacking. They try to hack the system with scripts from other fellow hackers. They try to hack the systems, networks, or websites.

Motives & Aims:

One standard Kiddie Script attack is a DoS (Denial of Service) or DDoS attack (Distributed Denial of Service). This simply means that an IP address is flooded with too many excessive traffic that it collapses.

Above are 3 types of hackers broadly referred to in the cybersecurity world.

The three types of hackers listed below work in different capacities.

1) State/Nation Sponsored Hackers

Government appoints hackers to gain information about other countries. These types of hackers are known as State/Nation sponsored hackers. They use their knowledge to gain confidential information from other countries to be well prepared for any upcoming danger to their country.

2) Hacktivist

These types of hackers intend to hack government websites. They pose themselves as activists, so known as a hacktivist. Hacktivist can be an individual or a bunch of nameless hackers whose intent is to gain access to government websites and networks.

3) Malicious insider or Whistleblower

These types of hackers include individuals working in an organization who can expose confidential information. The intent behind the exposure might be a personal grudge with the organization or the individual might have come across the illegal activities within the organization.

Conclusion

Understanding the different types of hackers, what motivates them, and the malware they use can help you identify the attacks you are most likely to face and how to properly defend yourself and your organization.
