How they hack your website_ the ultimate, updated overview of common techniques

Nine years ago, CMSWire created a useful overview of common techniques. Yale b database As the New Year begins, we felt it was time to update our answer to this ongoing question.

As you might have guessed, there is no one answer.


Sybase database So we’ve summarized the most popular hacking methods being used today to create the ultimate guide to modern hacking techniques. Database design 1. Database 3 normal forms DDoS Attacks

A distributed denial of service (DDoS) attack is technically not a hack, since it doesn’t give the attacker access to the target’s data. Database for dummies However, DDoS attacks are still a big concern for major (and minor) online brands.

The hacker (or hacking group) behind a DDoS attack will use a large batch of previously hacked or malware infected computers in order to carry out their attack. A database is a collection of This group of computers is referred to as a botnet, which the hacker can remotely instruct to access the targeted website over and over again in an attempt to overwhelm the servers — thus bringing it down.

The famous 2016 attack on the DNS provider Dyn was in fact a series of DDoS attacks, the likes of which the internet had never seen before. Library database Interestingly though, the botnets used in that case were made up mainly of IoT devices, rather than traditional computers or laptops. Database node 2. Data recovery after format Injection Attacks

When a hacker injects code into a website or program to execute remote commands that can read or modify a database — that’s called an injection attack.

SQL injection attacks are prevalent because they can be started from easily accessible input fields like contact forms, login forms and anywhere else where the website or app allows for public user input.

The attacker uses these input fields to make SQL queries in an effort to interact with the website’s database and uncover sensitive information. Database 2015 An attacker may also be able to modify the database on the spot.

That’s just one of many ways an attacker can use SQL injection to access a database, and if it doesn’t work, there cheat-sheets all over the internet for login strings that can gain access to weak systems. Data recovery nyc 3. Database weekly Cross-Site Scripting (XSS)

A cross-site scripting attack, also known as an XSS attack, is actually a form of code injection. Data recovery utah However, thanks to its growing popularity, I’ve decided to talk about it separately.

In a cross-site scripting attack, the attacker injects malicious code into a legitimate web page that then runs malicious client-side script when the victim visits said web page. Data recovery deleted files How It Works

To run malicious scripts in a victim’s browser, an attacker must first find a way to inject a that code into a web page that the victim will visit.

For that to happen, the hacker will need to identify a vulnerable website that the victim visits. Database health check For example, if an attacker spied the following vulnerable code on a website, they might have a chance:

This piece of code displays the most recent comment from the site’s comments database for everyone to see. R studio data recovery software This makes the website vulnerable because a hacker could submit a comment that contains a malicious payload such as:

By doing this, the website will display that comment — along with the malicious script — to anyone who visits. Data recovery iphone Resultantly, the attacker’s malicious script will execute within every visitor’s browser.

Such a script could give the hacker access to the visitor’s cookies (which is called cookie stealing) as well as the ability to send HTTP requests. Ease use data recovery More unnerving however, is the fact that JavaScript in modern browsers can leverage HTML5 APIs to access a user’s geolocation, webcam and microphone.

For additional information on cross-site scripting, here’s a great overview of what can be accomplished through XSS. Free database software 4. Raid 0 data recovery software Cross-site Request Forgery

Cross-site request forgery (CSRF or XSRF) is an attack that forces a logged in user to perform an action on a website without their knowledge. Mail database How It Works

A cross-site request forgery attack happens when a user is logged into an account, and a hacker uses this opportunity to send them a forged HTTP request to carry out an action on their behalf.

A hacker sends out a mass email to people that are clients of a (poorly secured) online payment company. Hdata recovery master The email contains a large sparkly image that invites the reader to a discounted online sale. In database But here’s what that image really looks like:

As you can see, any unsuspecting bargain hunter who clicks on the image will trigger a script that instructs their logged in session — which is open in the next tab over — to send funds directly to the hacker’s account.

Also referred to as DNS cache poisoning, this hacking method allows the attacker to divert traffic from legitimate servers to a malicious ones — leading unsuspecting website surfers to malicious script bearing websites. Drupal 7 database query How It Works

To spoof a DNS, a hacker must introduce corrupt domain name system data into a DNS resolver’s cache. Data recovery usa By taking control of where the DNS directs requests, the hacker can steal information and redirect traffic.

Commonly, hackers use this method to divert traffic from legitimate websites to malicious ones, where they might launch another type of attack.

This increasingly popular hacking technique entails the attacker convincing the victim to part with sensitive information — like a credit card number — in good faith. Data recovery business It’s less about code, and more about sneakiness. Database visualization How It Works

Phishing is perhaps the most popular form of social engineering, and one common way hackers engage in phishing is to send emails pretending to be from a reputable company.

They then confidently ask for the victim’s personal information, including passwords and credit card numbers in order to supposedly assist them.

Another classic phishing example is the “Microsoft tech support” scam, where malicious callers pretend to be calling from Microsoft in an attempt to extract emails, passwords, and payment information from unsuspecting Microsoft users. Data recovery qatar It’s an age-old way to hack, and yet it’s rampant even today. Data recovery no root 7. Database keywords Symbolic Linking

A symbolic link, or symlink, is method used to hack Linux servers. Normalization in database The symbolic link is essentially a shortcut, much like the shortcuts Microsoft users know and use.

The hacker can create a symbolic link from his directory, where he has limited permissions, to the root directory — where he shouldn’t have any permissions. Database 3nf A company employee with limited access to the root server for example, could perpetuate an inside job through a symbolic link.

Access to the root server gives the hacker the opportunity to change files, change permissions, insert malicious code and expose data. Database server 8. Data recovery wd passport Arbitrary Code Executions

This hacking technique describes an attacker’s ability to execute any command on a target computer. Relational database management system When the victim machine is separate from the attacker’s machine, this act is often referred to as remote code execution. Database generator How It Works

Arbitrary code execution is often performed by taking control of a program’s instruction pointer (or program counter), which points to the next line of code that is to be processed. Database 3nf example This can be done via malware infection (more on that later).

By changing the instruction pointer to instead point to the attacker’s malicious code, the attacker can then gain control of the user account running on that machine. Data recovery hard drive software From there, the attacker attempts to escalate the user’s privileges (if needed), in order to fully take over the machine for use in future attacks — like a DDoS attack. Iphone 4 data recovery 9. Database logo Clickjacking

Clickjacking is the practice of manipulating a website user’s clicks by concealing hyperlinks beneath clickable content, like a video play button. Moto g data recovery Using this sneaky tactic, attackers can trick website surfers into clicking on a link that they were unaware of.

After reading that, you’re probably thinking about all the times your clicks were jacked, as it is indeed a common tactic among shady movie streaming websites. Database analyst salary However, their intentions are usually less to do with hacking, and more to do with ad clicks. Data recovery engineer How It Works

Clickjacking is a simple case of hiding hyperlinks beneath something that a website user will actually want to click. Gt m database This could be a video play button or a social sharing button.

If the clickjacking is malicious, the attacker can send the victim to another website, where another type of attack (like a cross-site scripting attack) could be launched. In databases information is organized in 10. Data recovery tools iphone Google Hacking

Google hacking is when a hacker tries to find exploitable targets and sensitive data by using search engines like Google. A database driver is software that lets the It sounds easy, because it kind of is. 7 data recovery suite key How It Works

The Google Hacking Database (yes, there’s an actual database) is home to a long list of queries that you can search on Google. Data recovery linux Each of these queries is designed to identify sensitive data — or vulnerable web pages — on websites across the web.

Google has done its part by blocking most Google hacking queries, but hackers got around that by using their own tools to crawl websites before applying the queries directly onto the crawled content. Database modeling tools 11. G info database search Malware

In short, the word malware can be used to describe any software that’s designed to damage or otherwise compromise a computer system or its data. Database administrator salary How It Works

There are countless ways for hackers to get victims to download malware, and with over 1 million new pieces of malware emerging every day, the threat is very real.

Malicious software is often disguised as commonly downloaded music or video files, but in a ‘Bait and Switch’ attack, the hacker disguises their code as authentic software, tricking victims into downloading and installing it.

Trojan horse viruses get introduced alongside things like email attachments and other downloads that victims would otherwise trust. Database triggers They then act as a backdoor, contacting a remote controller, which can then gain unauthorized access to the affected computer.

The purpose of a keyloggers on the other hand, is to record the keystrokes of the affected computer’s owner. Data recovery recuva From those recorded keystrokes, the hacker can figure out passwords and other sensitive information. Data recovery texas 12: Fake Wireless Access Points

Hackers regularly set up fake wireless access points (WAPs) in order to lure the free Wi-Fi scrounger that exists within us all. Database resume How It Works

Once you’re connected to a hacker-managed Wi-Fi spot, the hacker can (potentially) see everything you’re doing. Data recovery external hard drive mac That includes typing in passwords and credit card information.

Hackers set these fake WAPs up in busy areas in order to draw in more people. Database management systems This kind of attack is called a ‘Waterhole Attack’. 7 data recovery review 13. Mode s database Brute Force Attacks

If, like me, you’ve ever tried to gain access to your sibling’s Facebook account by guessing the password repeatedly, you can consider yourself a seasoned brute force hacker.

Essentially, brute force hacking is the act of repeatedly trying different passwords or encryption keys in order to get the right answer. Windows 8 data recovery How It Works

At the grassroots of brute force attacking, you’ve got me guessing my brother’s Facebook password. Java 8 database But at the other end of the spectrum, advanced hackers are deploying brute force attack tools that automate the process on a grander scale. Database tools In other words, it’s trial and error on steroids.

The real danger here is that many of us use the same passwords for multiple accounts — both personal and professional. Drupal 7 database api So, if a hacker can crack your Gmail password, there’s a good chance they’ve cracked the password for your company’s intranet, too. Raid 6 data recovery 14. Database architecture Directory Traversal Hacks

Also known as path traversal attacks, this hacking technique can give an attacker access to files, directories, and commands that are located outside a website’s root directory. Iphone 4 data recovery software How It Works

An attacker can type in malicious character sequences into a URL in such a way that the website executes an action or discloses content from the web server.

The ../ (known as the dot-dot-slash hack) sequence is a common sequence that is used by an attacker to access files or to execute commands on the file system.

Buffer overflow attacks are primarily used against (poorly built) apps and operating systems. Database java Essentially, the attack aims to overflow the app or program’s memory buffer with useless data. Data recovery android How It Works

When an app, program or operating system needs to move data, it often stores it in a temporary location built to store excess data in transit. C database tutorial This excess data storage location is called the buffer.

When that buffer zones fills up and overflows, it’s possible for an attacker to then write or rewrite into permanent areas of the program, which can house executable code. Data recovery services cost Naturally, such an attacker would write something malicious enough to grant them access to the host computer.

Encryption protocols help protect the user information flowing through major websites and messaging services. Data recovery professional It’s a system that keeps our data and private messaging safe from prying eyes.

There are many ways to bypass an encryption. Data recovery images Some hackers leverage the combined processing power of their botnets to carry out brute force attacks. Database management system Others hunt for the algorithms the encryption software uses in order to crack the code.

However, like the with the famous Heartbleed vulnerability, most hackers exploit existing weaknesses in popular Transport Layer Security (also known as SSL) protocols to gain access to encrypted data. Sony xperia z data recovery More recently, the LogJam vulnerability has given rise to more attacks. Note 3 data recovery 7 Quick Tips: How Not To Get Hacked

• If your CMS provider has a development blog, subscribe to it. Database image Not only will it give you a heads up on any security issues that might impact you, but you’ll also be in the loop regarding imminent updates — as well as what the provider is protecting you from.

• Whenever a website offers it, always make use of two-factor authentication. S note data recovery This security feature requires users to not only enter a password, but also to confirm entry with another item of information, like a code texted to your phone. Database 4d It’s not unhackable, but it is highly secure.

• If you’re using enterprise software, the vendor likely provides you with ongoing support. List of data recovery software Make use of this by regularly touching base with the vendor regarding their next security releases, and how you can build up your website’s defenses even more.

• If you have an admin login page for your custom built CMS, disguise its importance by naming it something like ‘blogging.php’. Types of data recovery Calling it “AdminLogin.php” is simply inviting trouble.

• Enter some confusing data into your website’s search and login fields like the sample Injection strings shown above. Data recovery android app If you get an unusual error message disclosing server-generated code — take action.
