What is GoldenEye Ransomware?

GoldenEye has often been referred to as the king of ransomware, because it is considered as probably the worst ransomware ever created.

GoldenEye is a variant of the notorious Petya ransomware that also takes advantage of the same EternalBlue exploit to spread from one device to another. It encrypts the entire hard disk drive and denies you access to your computer.

How Does It Work?

GoldenEye encrypts certain files on your computer as well as the hard drive itself.

GoldenEye variant goes one step further than Petya ransomware because it has two layers of encryption. One of them individually encrypts target files on the computer, and the other one encrypts NTFS structures, preventing victim PCs from being booted up and retreiving stored information or samples.

GoldenEye is distributed using a spam email message. It takes place after a victim opens an infected email and enables macro settings.

If you get infected you will see the following image of a skull on a yellow background. Under the skull, there is a short text that says: ”Press any key!”

Untitled

If you press any key, the text with instructions on how to pay the ransom and retrieve your data will appear on your screen:

What Is So Special About GoldenEye?

The latest version of this ransomware was detected to be the German version. While Petya was designed to encrypt the data, GoldenEye was specifically designed to destroy them.

The user is unable to access the Windows operating system until the ransom is paid via the TOR Browser. The TOR page requires a CAPTCHA to access, the user is then presented with a page in which the personal identifier must be entered.

After the encryption process has been completed, the ransomware has a specialized routine that forcefully crashes the computer to trigger a reboot that renders the computer unustable until you pay the ransom of $300.

It has had its biggest impact on companies in Ukraine.

Will I Get My Data Back If I Pay The Ransom?

There is a possibility of paying the ransom to the hackers. But does not mean you will get your data back, because GoldenEye was specifically created to destroy all data.

How To Prevent GoldenEye Ransomware From Infecting My PC?

To prevent Petya, GoldenEye or any other type of malware from infecting your PC, it is crucial to have an antivirus software installed on your PC as a basic protection together with an antimalware protection that will serve as an additional layer of protection. Also, you need to have backup for your personal documents.

GoldenEye Removal

Unfortunately, once your PC has been infected and your data encrypted, you cannot recover them. Antivirus and antimalware software can only remove the infection from your PC or they can block it/prevent it from infecting your PC if you were wise enough to have them installed on time. However, they cannot recover your encrypted files. Therefore, it is highly important to protect your files on time.

If you are using Zemana AntiMalware premium version (which comes with 15-days free trial), it will protect you by blocking the Cryptolocker ransomware on time. This way, it will prevent it from infecting your PC.

However, if you decide to continue using the Trial and do not wish to purchase the Premium subscription at the end of the trial, your Zemana AntiMalware program will disable premium features. All other (basic) features will remain unchanged. This means that you will no longer be protected from Petya, but you will still be able to scan your PC with Zemana AntiMalware, which will detect Petya and block it.

Therefore, the best prevention against Petya virus is installing the right protection solution even before you get infected.

What is Citadel Malware?

Citadel is a toolkit for distributing malware and managing botnets making it super easy to produce ransomware and infect systems one after another with pay-per-install programs. Citadel was designed to steal personal information, including banking and financial information from its victims.

The Citadel Trojan, based on the Zeus source code, constructs a botnet consisting of a considerable number of infected computers. The attacker can execute malicious code on an infected computer, including ransomware and scareware.

How Does It Work?

Citadel is installed on a victim’s computer with a drive-by-download attack most often using the Blackhole exploit kit. The Blackhole exploit kit is a cloud-based pay-for-service malware or malware as a service (MaaS) platform that installs web browser exploits on unsecured web servers for installing malware on victims’ computers. This Trojan was one of the earliest examples of malware-as-a-service available on dark-web forums.

When a user visits an infected website, Blackhole exploits a vulnerability in the user’s web browser to install Citadel.

Citadel could hijack control of users’ Windows PCs and even attempt to grab the master passwords of some third-party password managers, and block access to anti-virus vendor websites.

Citadel could also be used in targeted attacks exploiting Microsoft zero-day vulnerabilities to infect firms, as well as more traditional attacks.

What Is So Special About Citadel Malware?

The author of Citadel Trojan, Mark Vartanyan, who went by the online handle of ‘’Kolypto”, was arrested in the Norwegian town of Fredrikstad in 2015 at the request of the FBI.

Vartanyan admitted his guilt as a plea bargain with US federal prosecutors who have agreed not to seek a prison sentence of more than ten years.

 How To Prevent Citadel From Infecting My PC?

The best way to prevent Citadel from infecting your PC is to avoid visiting unsafe websites, especially banking websites. Your PC can also get infected via exploits in different browsers. Therefore, you need to install an antivirus solution as the basic protection for your PC and an antimalware solution as the necessary additional layer of protection. Make sure to keep them both updated.

How To Remove Citadel From a PC?

If you are looking for a solution to detect or to protect you from Citadel, download Zemana AntiLogger for free (it comes with 15-days free trial). It will detect any type of malware on your PC and remove it.

How to Remove AndroRAT?

AndroRAT – What Is It And How To Remove It?

AndroRAT is a contraction of Android and RAT (Remote Access Tool). It is a piece of malware we have seen a lot lately. At first it was created as a proof of concept. However, this malware has gradually become more evolved over the years. It allows a remote attacker the control over the victim.

Usually the RATs have a user-friendly control panel that makes it possible to control the victims. As a result, AndroRAT can control the infected device by making phone calls and sending SMS messages as well as getting its GPS coordinates. It can also access the files stored on the handset and easily activate and use both the microphone and the camera.

How Does It Work?

The new version of this malware has an ability to gain some advance level privileges on any Android device that unpatched Remote code execution vulnerability CVE-2015-1805 and inject root exploits.

It exploits the critical vulnerabilities on the targeting platform.

What Is So Special About AndroRAT?

Apart from Android, AndroRat can also target Windows and macOS platforms. RAT will communicate with the command and the control server which is controlled by the attacker. It will perform various commands to steal the user’s sensitive information.

Some of these commands are stealing your contact list, your GPS location, your files, messages from your inbox, your WiFi passwords, etc. It can upload files to your device, record audio and capture your screen.

The implanted AndroRAT allows an attacker to remotely control it. This means, the attacker can monitor and make calls and messages. Similarly, he can easily activate the camera and microphone, and access stored files.

How To Prevent AndroRAT From Infecting My Phone?

In terms of security Android is much safer to use then its Windows counterpart – but it is by no means impenetrable. Therefore, you should be careful when downloading different apps because a large number of positive reviews is not always an indication that an app is safe.

What Is Stuxnet Virus And How Does It Work?

What Is Stuxnet Virus?

 
Stuxnet Virus is a rootkit exploit that targets supervisory control and data acquisition (SCADA) systems. SCADA systems are used widely for industrial control systems, such as power, water and sewage plants, as well as in telecommunications and oil and gas refining.
When Stuxnet Virus was first discovered, its purpose wasn’t fully understood. However, it was clear it had a complex design. Many believe that a team of expert programmers working over a period of several months created it.

How Does It Work?

 
Stuxnet Virus spreads via the internet and on USB sticks, just like most other viruses. And the way it does this is not particularly clever or well hidden. To reach its target, Stuxnet Virus needs to spread via USB sticks.
USB sticks allow it to penetrate industrial systems disconnected from the Internet and thought to be safe from malware. However, apparent mistakes mean it also spreads via the Internet.
Once Stuxnet infects a computer, the worm copies itself to any flash drives subsequently connected to the computer. It then spreads from those flash drives to other computers.

What Is So Special About Stuxnet Virus?

 
Like the Zeus banking Trojan, Stuxnet code covered its tracks using stolen digital certificates to trick the operating system into letting Stuxnet Virus install a rootkit. The malware could also avoid detection by traditional intrusion detection systems (IDS).
Many believe that programmers did not design Stuxnet for espionage, but rather to wipe out a large portion of Iran’s nuclear centrifuges.
It was designed to limit the acceleration of its spread by infecting a maximum of three computers from a single flash drive. Additionally, Stuxnet was very good at hiding on systems.

Who Was Stuxnet Aimed At?

 
Even though the Stuxnet makers included measures to limit its spread, something went wrong.
Stuxnet was aimed at a specific target list – experts designed it to infiltrate heavy-duty industrial control programs that monitor and manage factories, oil pipelines, power plants and other critical installations.
Somehow, it spread to thousands of PCs outside Iran, in countries such as China and Germany, Kazakhstan and Indonesia.

How To Remove Stuxnet From a PC?

To remove Stuxnet from your PC, try Zemana AntiMalware, which you can download for free (it comes with 15-days free trial). It will successfully detect Stuxnet on your PC and remove it.

How To Remove Svchost.exe Virus?

What Is SvcHost.exe?

Generally, svchost.exe is a non-malicious program required for Windows. It is a process used to host one or more Windows operating system services.
Because it is used as a common system process, some malware often uses a process name of “svchost.exe” to disguise itself. The original system file is located in C:\Windows\System32 folder. Any file named “svchost.exe” located in other folder can be considered as malware.

How Does It Work?

Because svchost.exe is a common process in the Task Manager, malware programs sometimes mask themselves by running under the same process name. Other times, a malware program may run, or inject, its service into an already running svchost.exe process. In either case, this masking action can make it difficult to detect and remove these malware programs.

What Is So Special About SvcHost.exe?

Even though it is a common process in the Task Manager and malware programs sometimes masquerade themselves by running under its name, sometimes a malware program may run into an already running clean svchost.exe process. This corrupts the original process and turns it into a virus.
It may often duplicate or copy their executable to the Windows system folders and later alter the registry to run this file every time you start your system.
To remove this process, you need to delete its segments or components. However, if you remove a genuine svchost.exe process from your machine, your machine may crash down instantly. Therefore, you need to install an antivirus or an antimalware software on time (it would be the best to have both), because they are prepared to remedy such circumstances.

How Did I Get Infected With SvcHost.exe?

The Svchost.exe virus can be distributed in several ways. Malicious websites, or legitimate websites that have been hacked, can infect your machine through exploit kits that use vulnerabilities on your computer to install this Trojan without your permission or knowledge.
Another way of spreading this malware is spam email containing infected attachments or links to malicious websites. Usually, you would receive an email telling you that a shipping company failed at delivering a package for you.
If you open the attached file (or click on a link embedded inside the email) your computer gets infected.

How To Remove SvcHost.exe From a PC?

One of the best SvcHost.exe remover is Zemana AntiMalware and you can download it for free (it comes with 15-days free trial). It will detect spyware on your PC and remove it.
However, if you decide to continue using the Trial and do not wish to purchase the Premium subscription at the end of the trial, your Zemana AntiMalware program will disable premium features. All other (basic) features will remain unchanged.

Zemana AntiMalware as a SvcHost.exe removal tool for your PC

Manually removing can be quite complicated and you might not remove it completely. Therefore, you might need the help of an antivirus or anti-malware software.
Please follow the steps below to remove it completely with our Zemana AntiMalware:
STEP 1: Download and run Zemana Antimalware.
STEP 2: Once download, install the software on your PC. You can do this by double-clicking on ZAM program icon on your desktop or in your download files.
