Hacking Someone's Facebook Password Using Some Software Or Website? No Sir You Can't!

Hacking Someone's Facebook Password Using Some Software Or Website? No Sir You Can't!

facebook hacking
Do you know there are over thousands of websites and software that claim to hack Facebook password of any account? They'd ask you the victim's profile ID, maybe your credentials and some money too and will reportedly tell you the password which, to be honest, never works. Ever wonder why? Let me tell you why, they're FAKE! They're a scam which tricks you somehow in losing your money or your own Facebook account. Just give it a thought, why would Zuckerberg and his team spend Billions of Dollars on Facebook if one could hack it in less than a minute? Today, we'll take a look at this topic in detail with some example websites and software and get answers to some common related questions.

Back in 2005, I came across a mechanism that reportedly hacked Yahoo mail password for a user using some simple tricks. It didn't work for me for obvious reasons but I didn't stop believing the possibility until I grew up to realize how helpless I am here. One of the major concerns of large organizations like Facebook and Yahoo is security because of the super sensitive information about people they have. Several hundred million dollars are spend yearly by these organizations to ensure security and then there's these websites that claim to undo all that protection in less than a minute.

The Facebook password cracking Websites and Software

Let's start with some examples here. I googled the subject and picked the top results without order. Didn't care to search harder because there are thousands such and I know that all are FAKE.

So let's look at this GETFBHACK.com.
hacking facebook password
Their FREE Facebook hacker program is said to be capable of cracking the password of any Facebook user within a day. Sounds cool, I could try it out, but my Norton Antivirus rejected the file straight away.

I also picked up another one. This Hack-Fbook-Password asks me to enter the profile ID of a user and it will crack the password. I said Okay and began the process.
facebook hacking
It ran certain algorithms to determine the password and finally landed me on a page that said I could DOWNLOAD the password IF I fill an online survey first. Those of you who've been redirected to surveys would know they don't work and are put just so to get traffic and earn money.

I said maybe I should leave the website now but hey, they gave me a prize!
hacking facebook

So I just became the luckiest person in my city just like that!

Now tell me, how can a sane person believe in all this?

The truth!

Let me get this straight to you, these websites do nothing at all just waste your time and are never able to do the job. In fact, downloaded programs just make the situation worse when you run them. I had my Norton Antivirus to guard me otherwise I could be in severe danger currently.

These software are mostly keyloggers and tracking programs that record your keystrokes and action and steal personal information from your computer in the background and send it to their master servers. So ultimately a hacker wannabe gets hacked, how ironic!

From now on in the post, I'll be using the word 'Hacker' for these websites and software since you're no more in the position to be called that.

Why do these 'Hackers' do all that?

facebook hack
Setting up websites, maintaining them and developing software is not an easy task. It requires some money. So why do these 'hackers' do all the hassle? It's because they get equivalent or more money in return. They can extract your credit card details and other banking info from your system and use it for their advantage. They can hack your account and use it for wrong purposes. Give me one reason why one wouldn't steal money and hack accounts for no loss.

Why people fall in their webs?

facebook hack
Why do people try to use such unreal hacking procedures? It's because it's unreal to me, it's unreal to you but not to those who are not much familiar with the working of a software. They get in the web of these hackers and eventually get screwed up pretty bad without consent.

The websites give guarantees and also portray their 'imaginary' happy customers so as to trick a reader. Such tactics are simple but really powerful and serves to their advantage in most cases. This is also why there are thousands of such websites available.

So is Facebook account an 'unbreakable fortress'?

facebook hacking
Well, NO. Facebook accounts can be hacked. No online service is foolproof and that is because of the flaws and bugs in their software. There are several ACTUAL hackers in the world who can analyse a website's security and use that against it thus making hacking a reality.

But I'm 100% sure none of them uses these scam and fake websites that claim to do the impossible. You can check out our hacking section to know more.

I'll end the 'lesson' with an idiom, "look before you leap". Focus, think and then follow. In case of any queries or confusions head over to the comments section. Cheers :)

6 Most Common Password Cracking Methods And Their Countermeasures

6 Most Common Password Cracking Methods And Their Countermeasures

6 method used to crack passwords
There are number of methods out their used by hackers to hack your account or get your personal information. Today in this post i will share with you guys 6 Most commonly used method to crack password and their countermeasures. You must check out this article to be safe and to prevent your online accounts from hacking.

1. BruteForce Attack

brute force attack
Any password can be cracked using Brute-force attack. Brute-force attacks try every possible combinations of numbers, letters and special characters until the right password is match. Brute-force attacks can take very long time depending upon the complexity of the password. The cracking time is determined by the speed of computer and complexity of the password.

Countermeasure: Use long and complex passwords. Try to use combination of upper and lowercase letters along with numbers. Brute-force attack will take hundreds or even thousands of years to crack such complex and long passwords.
Example: Passwords like "iloveu" or "password" can be cracked easily whereas computer will take years to crack passwords like "aN34lL00"


2. Social Engineering

Social engineering is process of manipulating someone to trust you and get information from them. For example, if the hacker was trying to get the password of a co-workers or friends computer, he could call him pretending to be from the IT department and simply ask for his login details. Sometime hackers call the victim pretending to be from bank and ask for their credit cards details. Social Engineering can be used to get someone password, to get bank credentials or any personal information.

Countermeasure: If someone tries to get your personal or bank details ask them few questions. Make sure the person calling you is legit. Never ever give your credit card details on phone.

3. Rats And Keyloggers

keylogger
In keylogging or RATing the hacker sends keylogger or rat to the victim. This allows hacker to monitor every thing victim do on his computer. Every keystroke is logged including passwords. Moreever hacker can even control the victims computer.

Countermeasure: Never login to your bank account from cyber cafe or someone else computer. If its important use on-screen or virtual keyboard while tying the login. Use latest anti-virus software and keep them updated. Check out below article to know more about Rats and Keyloggers.

4. Phishing

phishing hacking
Phishing is the most easiest and popular hacking method used by hackers to get someone account details. In Phishing attack hacker send fake page of real website like facebook, gmail to victim. When someone login through that fake page his details is send to the hacker. This fake pages can be easily created and hosted on free web-hosting sites.

Countermeasure: Phishing attacks are very easy to avoid. The url of this phishing pages are different from the real one. For example URL of phishing page of facebook might look like facbbook.com (As you can see There are two "b"). Always make sure that websites url is correct. Check out below article to know more about phishing.

5. Rainbow Table

A Rainbow table is a huge pre-computed list of hashes for every possible combination of characters. A password hash is a password that has gone through a mathematical algorithm such as md5 and is transformed into something which is not recognizable. A hash is a one way encryption so once a password is hashed there is no way to get the original string from the hashed string. A very commonly used hashing algorithm to store passwords in website databases is MD5. It is almost similar to dictionary attack, the only difference is, in rainbow tables attack hashed characters are used as passwords whereas in dictionary attack normal characters are used as passwords. 

Example: ‘hello’ in md5 is 5d41402abc4b2a76b9719d911017c592 and zero length string ("") is d41d8cd98f00b204e9800998ecf8427e

Countermeasure: Make sure you choose password that is long and complex. Creating tables for long and complex password takes a very long time and a lot of resources

6. Guessing

password guessing
This seems silly but this can easily help you to get someones password within seconds. If hacker knows you, he can use information he knows about you to guess your password. Hacker can also use combination of Social Engineering and Guessing to acquire your password.

Countermeasure: Don't use your name, surname, phone number or birthdate as your password. Try to avoid creating password that relates to you. Create complex and long password with combination of letters and numbers.

Black Hat White Hat and Gray Hat Hackers Definition


Black Hat White Hat and Gray Hat Hackers Definition 

 

Ethical Hacking is considered as a craft of busting into personal computers or systems with an objective to investigate it, examine it and ultimately protecting it. I regard it as being an art and craft due to the fact few people can hack. A hacker, usually, can be a person which has a myriad of knowledge in diverse computer topics and terminologies  that requires considerable time, vigor and intelligence.


Black Hat Hackers

Black Hat Hackers that are also referred to as Crackers are people who enter computer systems and networks without any prior authorization. They may be the individuals who break many different reasons for example thievery, retaliation, showing-off their skills, causing destruction or perhaps any random motive. Black Hat Hackers can be deemed the new criminals in this electronic age. Several federal laws and regulations are already enacted to curb Black Hat Hacking. The IT Act 2000 which can be then several countries have listed out several ways to cope and penalize Black Hat Hackers. Many network security agencies are formed after several hacking cases being reported. These agencies work for planning security policies and actions to protect companies and folks alike from getting hacked.

Grey Hat Hackers

Grey Hat Hackers are hackers that have designed their own good reasons to hack computers and networks. They're like Robin Hoods of today's age. They can be seen as a mixture of White Hat and Black Hat Hackers. Grey Hat Hackers can perform good for some individuals which enables it to even cause damage based on their approach. One example is, Grey Hat Hackers commonly hack sites they will feel is socially bad like adult and gambling sites. Some from these breed of hackers hack systems and networks, find out the weaknesses and loop holes and report them to the particular organizations or owners. This is done exclusively for getting recognition, showing-off or some of their own motives and dreams.

White Hat Hackers

White Hate Hackers are the type who are known as ethical hackers. These are the basic ones who practices values, ethics, abides because of the laws yet still hack! It seems like strange, but yes, that's the actual way it is! This is one way it happens - an ethical hacker is authorized to hack computers or networks and that he tries his best to hack it. Now the dilemma arises - why? A distinct respond to that is that unless we have an knowledge of what is insecure in your system or network, we will never manage to protect it. An ethical hacker supplies with vulnerabilities or loop holes from the system or network through extensive usage of various hacking tactics. These weaknesses and faults are then typically fixed through restorative and preventive measures. 

 

 

Backdoor


Backdoor or "back door", in the security computer system, refers to mechanisms that can be used to access the system, application, or network, apart from the general mechanisms that are used (through the logon process, or other authentication process). Is also known as a back door.

Backdoor initially created by computer programmers as the mechanism that allows them to obtain special access to them in the program, often used to justify and improve the code in the program that they created when a crash occurs due to a bug.

The term now used by the backdoor hacker-hacker to refer to a mechanism that allows the system can access peretas back a system that has been attacked before the process without the need to exploit the system or network, as it did the first time. Generally, once a network has been attacked by using the exploit (to a Handling / Vulnerability), an attacker will cover all jejaknya in the system concerned with modifying the file system record (log) or delete it, and then menginstalasikan a backdoor in the form of a software or to add a special user account that has rights to access the network administrator or system administrator. If the owner and the network or system to realize that the system has been attacked, and then close all Handling is known in the system (but does not detect the existence of the backdoor installed), still before the attacker will be able to access the system, discovered by the owner without the network, especially after registering himself as a legitimate user in the system or network. Have the right as the network administrator, he can do things that can damage the system or remove the data. In cases like the above, a commonly used way is to make re-installation of the system or network, or with restoration of the backup / backup that is still clean from the backdoor.

An Ethical explanation of Ethical Hacking

Ethical hacking is usually a white hat approach, wherein the hacker breaches the protection of your computer system or network, to uncover the protection system's weaknesses. A job in ethical hacking, being an expert, has bright prospects taking into consideration the reliance on the planet on computer technology, and straightforward accessibility to internet.

What exactly is Ethical Hacking?
 In ethical hacking, the hacker identifies the weakness inside system, but instead of benefiting from the specific situation, alerts the webmaster/administrator, in order that the later can fix their vulnerabilities and earn his system secured. The ethical hacker can convey what it's all about for the owner by various means ranging from a straightforward telephone call to leaving an electronic card in the system, for obvious signal that the system was breached. Ethical hackers make use of the same tools as hackers do, but they are not really a threat somewhere. Many people do ethical hacking like a hobby, while some pursue it as their career.

 Ethical Hacking for Newbies
 It's very hard to defend yourself against a mystery enemy, similarly when it comes to hacking, it's difficult to fight them not understanding that they work. Hackers use various methods and tools to hack into a particular system, plus order to know their methodology, you have to find yourself in the hacker's shoes. Ethical hacking guides covers black hat methods utilized by hackers to vandalize your network, due to the security. Be careful to use your own computer to rehearse ethical hacking. You can try hacking your system to discover the loopholes from the security. You may also hack a family members PC, but make sure that you possess the permission to do so. Illegal hacking is regarded to be a severe Internet crime, and may earn around a decade imprisonment, hence it is wiser to consider necessary precautions.

 Computer security has changed into a major concern nowadays. Though ethical hackers can penetrate into your whole body and warn the administrators concerning the possible hacking attacks, is it doesn't administrators who've to get careful concerning the hazards of the advanced technologies. Make certain that laptop computer security is at place and the wonderful in control of the security are very well versed with changing concepts of computer malpractices.

 Simple requirements to Become an Ethical Hacker
 The ethical hacker needs to possess excellent programming as well as networking skills, as well as good working information about various OS's. One must be master of both Linus and Windows to become an Ethical hacker.  Each one of these skills should be supported with all the understanding of necessary hardware and software. Furthermore a certified ethical hacking or cyber security course is the basic requirement to become an ethical hacker. Ethical hacking isn't an operation which can be executed using a snap in the finger, being patient may be the important key, specially in ethical hacking for beginners. Sometimes, possibly you have to evaluate the machine for the days or weeks to have a single opportunity to hit the jackpot.

 Privacy on the client's info is just about the most predominant issue within the ethical hacking guide. While working away at a project, the ethical hacker comes across some vital information regarding an individual or the company. He should make sure that it data is kept secret. All the results, documented and electronic format, must be saved in safe custody. The data may mean a lot to the user or perhaps the company, thus the ethical hacker has to respect his client's priorities.

Script Kiddie


In hacker culture, a script kiddie, occasionally script bunny, skiddie, skid, script kitty, script-running juvenile (SRJ), or similar, is a derogatory term used to describe those who use scripts or programs developed by others to attack computer systems and networks. It is generally assumed that script kiddies are juveniles who lack the ability to write sophisticated hacking programs or exploits on their own, and that their objective is to try to impress their friends or gain credit in computer-enthusiast communities.The term can also be used as a name for someone with a good knowledge of computers who uses the premade tools as a shortcut or just for fun.

Script kiddies have at their disposal a large number of effective, easily downloadable malicious programs capable of harassing even advanced computers and networks.Such programs have included WinNuke applications, Back Orifice, NetBus, Sub7, Metasploit, ProRat and often software intended for legitimate security auditing.

Another simple means of attack is a mass mailer worm. These are spread through e-mails and, once opened, they can be automatically sent throughout entire systems, often without the users realizing it. The purpose of a worm varies, from sapping the targeted computer or network of bandwidth and therefore slowing performance, to deleting or encrypting files. Other commands are possible.

In a denial-of-service (DoS) attack, the attacker tries to shut down network activity in a target system by sapping the computer network of bandwidth or other resources. A number of distinct DoS attacks have been created that pursue this goal through different means, such as SYN flood, ICMP butt-flood (a.k.a Smurf attack) and ping floods. If the server gets overwhelmed with excessive amounts of information, it will stop responding and may require a restart.

Black Hat


A black hat is the villain or bad guy, especially in a western movie in which such a character would wear a black hat in contrast to the hero's white hat. The phrase is often used figuratively, especially in computing slang, where it refers to a hacker who breaks into networks or computers, or creates computer viruses.

Black Hat Hackers (also called "crackers"), are hackers who specialize in unauthorized penetration. They may use computers to attack systems for profit, for fun, or for political motivations or as a part of a social cause. Such penetration often involves modification and/or destruction of data, and is done without authorization and hence they should not be confused with ethical hackers.

They also may distribute computer viruses, Internet worms, and deliver spam through the use of botnets. The term may also refer to hackers who crack software to remove protection methods: copy prevention, trial/demo version, serial number, hardware key, date checks, CD check (NO-CD) or software annoyances like nag screens and adware.
