ransomware

What is ransomware?

Ransomware is a type of malware that encrypts a victim’s files and demands a ransom be paid to decrypt them. Ransomware is typically spread through email phishing campaigns or by exploit kits that take advantage of vulnerabilities on a target’s system. Once a system is infected, the ransomware will scan for specific types of files and encrypt them using a strong cipher. The victim will then be presented with a ransom note informing them of the encryption and demanding payment for the decryption key. Ransomware is a serious threat to businesses and individuals as the encryption is often very difficult to break and the ransom amount can be significant.

How can you protect yourself from ransomware?

There are a few things you can do to protect yourself from ransomware. First, make sure that you have a good backup strategy in place. This way, if you do get hit with ransomware, you will be able to restore your files from a backup. Second, keep your software up to date. Ransomware often takes advantage of vulnerabilities in outdated software, so keeping your software patched will help reduce your risk. Finally, be cautious when opening email attachments or clicking on links. If you are unsure about the sender or the content, it is best to err on the side of caution and not open it.

What should you do if you are infected with ransomware?

If you do find yourself infected with ransomware, the first thing you should do is try to isolate the infected system to prevent the ransomware from spreading. Then, you will need to decide whether to pay the ransom or attempt to decrypt the files yourself. If you do pay the ransom, there is no guarantee that you will get the decryption key and there is a risk that you will simply be giving the criminals more money. If you decide to try to decrypt the files yourself, there are a few tools that may be able to help, but there is no guarantee of success. In the end, it is often best to simply restore your files from a backup..Click here to find out more

drive-by downloads

What are drive-by downloads?
Drive-by downloads are unauthorised installations of software on a user’s device, most often accomplished without the user’s knowledge or consent. In many cases, the user unwittingly visits a website that hosts malicious code and their device is infected with malware as a result.

Drive-by downloads can result in a range of consequences for the user, from having their personal information and data exposed and stolen, to being used as a part of a botnet to attack other systems. In some cases, the malware installed by a drive-by download can be difficult or even impossible to remove.

How do drive-by downloads work?
There are a number of ways that drive-by downloads can be accomplished, but most often they exploit vulnerabilities in the user’s web browser or plugin applications (such as Adobe Reader or Flash Player).

In some cases, the malicious code is hidden in advertising on a website. When the user visits the site, the code is executed and the download begins without the user’s knowledge or consent.

In other cases, the code may be embedded in a malicious website or email attachment. When the user visits the site or opens the attachment, the code is executed and the download begins.

Still other methods make use of flaws in browser and plugin applications to force the download to start without the user’s knowledge or consent.

In all cases, the goal is the same: to install malicious code on the user’s device without their knowledge or consent.

What are the consequences of a drive-by download?
The consequences of a drive-by download can be significant. The malware installed on the user’s device can allow attackers to steal personal information and data, hijack the device to be used as part of a botnet, or cause other damage.

In some cases, the malware installed by a drive-by download can be difficult or even impossible to remove. This can result in the user’s device being permanently compromised.

What can you do to protect yourself from drive-by downloads?
There are a number of things you can do to protect yourself from drive-by downloads.

First, make sure your web browser and plugin applications are up to date. Attackers often exploit vulnerabilities in these applications to force the download to start. By keeping your applications up to date, you can reduce the risk of being vulnerable to these types of attacks.

Second, be careful about the websites you visit and the email attachments you open. Attackers often use malicious websites and email attachments to deliver the code that will begin the drive-by download. If you’re not sure about a website or attachment, don’t visit it or open it.

Finally, consider using a security application that can detect and block malicious code. These applications can help to protect you from drive-by downloads and other types of malware.
