A Comprehensive Guide on Ransomware

A Comprehensive Guide on Ransomware

Ransomware, which demands payment after launching a cyber attack, has become a rising trend among hackers looking for a quick payout. While initially popular in Russia, the use of ransomware scams has grown internationally. It is one of the world’s fastest-growing types of Malware and it is as scary as it sounds. Ransomware attack puts you in a sticky situation, so it’s important to know about Ransomware protection and how to avoid it.

What is ransomware?

Ransomware is a type of Malicious Software which is designed to extort money (ransom) from the user. This cyber attack involves hackers taking control of the computer and blocking access or encrypting all the files until a ransom is paid. And it displays how and how much ransom should be paid in order to decrypt your files.

Simple ransomware may only lock the PC but more other advanced malware encrypts the victim’s files, making them inaccessible. Paying the ransom (either through credit card or Bitcoins) however, does not guarantee that you’ll get your files back. Ask an Apple UK expert for a quick fix.

Types Of Ransomware

They are of two types – screen lockouts and encryption ransomware.

Lockscreen ransomware shows a full-screen message that prevents you from accessing your PC or files. It says you have to pay money (a “ransom”) to get access to your PC again.

Encryption ransomware changes your files so you can’t use them. It does this by encrypting the files.

CryptoLocker is a file-encrypting ransomware. It encrypts the personal documents found on your computer using RSA-2048 key (AES CBC 256-bit encryption algorithm). Older versions of ransomware usually claim you have done something illegal with your PC, and that you are being fined by a police force or government agency. This type of ransomware attack generally comes when visiting porn websites.

These claims are false. It is a scare tactic designed to make you pay the money without telling anyone who might be able to restore your PC.

What are Ransomware

How Ransomware Infects Your Computer?

The Malware can get onto your computer in multiple ways. It can get on your PC from nearly any source that any other malware (including viruses) can come from. These sources are: Visiting suspicious, infected or compromised website. Opening emails and email attachments or link from people you don’t know. Downloading fake or look-alike software like Flash Player or Java OR bundled with other software.

Once the software is installed on your computer the hackers can launch an attack. And they will have the complete access of your computer and all its files. that locks all files it can find within a network. This tends to be a gradual process with files being encrypted one after another.

What does ransomware do?

Once it is installed, it locks your computer and prevents you from using your PC normally. If it is CryptoLocker, it will encrypt the hard drive. Which makes it impossible to access or retrieve anything stored on your computers – such as photographs, documents or music.

It can:

Prevent you from accessing Windows.
Encrypt files so you can’t use them.
Stop certain apps from running (like your web browser or security software)

After locking or encrypting it will show you a message like the one shown below. In the message, Ransomware will demand that you pay a ransom to get access to your PC or files. There is no guarantee that paying the fine or doing what the ransomware tells you will give access to your PC or files again.

Some Microsoft Edge Browser Security Features

Some Microsoft Edge Browser Security Features

We take a look at some of the Microsoft Edge browser security features. Microsoft launches Windows 10 with two built-in browsers: Microsoft Edge and Internet Explorer 11. Microsoft knows that Internet Explorer isn’t the most popular browser out there. And it also have very bad reputation in terms of speed and security. This prompted Microsoft to launch a new browser and get involved in the browser business. The new Microsoft Edge browser has a lot to offer in terms of performance and security. Microsoft Edge browser security features have been enhanced along with some new features and performance to compete with other web browsers.

Some Of The Microsoft Edge Browser Security Features

Internet Explorer is not very popular browser out there. But with the arrival of Microsoft Edge in Windows 10 Microsoft is looking to be a serious player in browsers market. In fact, according to Microsoft’s blog, Edge was built with security as its highest priority. According to a post by Team Microsoft in their May 11 blog:

“With Microsoft Edge, we want to fundamentally improve security over existing browsers and enable users to confidently experience the web from Windows. We have designed Microsoft Edge to defend users from increasingly sophisticated and prevalent attacks.”

A good browser should be capable of protecting you and your data from malicious threats. Let’s take a look at some of the Microsoft Edge browser security features.

Microsoft SmartScreen

Microsoft SmartScreen, used in both Internet Explorer 11 and Microsoft Edge, was introduced with IE8. It is a very important component of both Microsot Edge and Windows 10. It protects users from phishing sites by performing a reputation check on the websites they are browsing. If the website is ok, SmartScreen will allow you to proceed and if anything looks suspicious, the browser will give you warning. SmartScreen also helps to defend people against being tricked into downloading and installing malicious social-engineered software. It also helps users against drive-by attacks. Drive-by attacks are malicious web-based attacks that compromise your system by targeting security vulnerabilities in commonly used software, and may be hosted on trusted sites.

The best part in SmartScreen is integrated not only to Edge but alo into Windows 10 shell and other aps. This has an added advantage as some apps try to connect to websites on their own – without the need for browser. SmartScreen in Windows 10 Shell will prevent them from connecting to phishing or malicious websites.

Microsoft Edge Browser Security Features

Sandboxing the Edge App

A major security issue with Internet Explorer was that the browser was built directly into Windows. This meant that if the browser was infected or compromised, your entire computer might be taken down along with it. So Microsoft decided to sandbox Edge browser to provide more security.

Sandboxing is a security term for executing a program or software in a contained environment so it cannot affect any other programs that may be running on a device. This means better security for the end user because if Edge is compromised, the rest of the computer won’t be harmed.

This will prevent attackers from gaining control of all of your computing resources. Even if they gain access to the Edge browser, they will be sandboxed and put there, so that they can’t go ahead and compromise your computer.

HTML and Modern Web Standards

Microsoft Edge has a new rendering engine called Microsoft EdgeHTML. It is focused more on modern standards of security and rendering so that web developers can build and maintain websites across all modern browsers. The Microsoft EdgeHTML engine supports W3C standards for Content Security Policy (CSP). It help web developers defend their sites against cross-site scripting attacks. It also have support for HTTP Strict Transport Security feature. This helps ensure that connections to important sites, such as to your bank, or e-commerce websites are always secured.’

Microsoft Edge is a 64-bit app

Microsoft Edge runs in 64-bit not just by default, but anytime it’s running on a 64-bit operating system. Because Microsoft Edge doesn’t support legacy ActiveX controls or 3rd-party binary extensions, there’s no longer a reason to run 32-bit processes on a 64-bit system. The value of running 64-bit all the time is that it strengthens Windows Address Space Layout Randomization (ASLR).

ASLR randomizes the memory layout of the browser processes, making it much harder for attackers to hit precise memory locations.

In turn, 64-bit processes make ASLR much more effective by making the address space exponentially larger and, therefore, more difficult for attackers to find the sensitive memory components they’re looking for.

Windows Hello

Microsoft Edge is the first browser to natively support
Windows Hello as a more personal, seamless and secure way to authenticate your identity on the web. Windows Hello is Microsoft biometric sign-in system. It helps in authenticating your identity using your face, fingerprint, iris or even heartbeat detection gathered from a wearable device, which are unique to you, instead of traditional passwords.

Windows Hello was first introduced as a means of signing into your Windows account, but after the Windows 10 Anniversary Update, it’s now supported in Microsoft Edge. Not only is Windows Hello more convenient than typing a password—it’s more secure!

Edge contains several major security enhancements that help protect users from phishing or hacking attacks.
