After ransomware emails, now cybercriminals have included more methods in their arsenal. Exploit kits are one of the more popular ones of the lot among hackers. These malicious exploit kits work more silently and are often difficult to detect. Therefore, it is important to know how they work to avoid them.
Generally, exploit kits work through offers that look too good to be true. The problem with these offers is that they are not legitimate like Cox internet deals and real services. Hackers push these offers just to lure people into visiting their fake websites. So, it is best to be more careful while browsing.
What are Exploit Kits?
Ransomware emails have been the weapon of choice for a lot of hackers in the past. The sender would impersonate some friend or colleague and ask for help with a file. That attached file has ransomware. Usually, such emails look like sincere calls for help. But once you download and open the file, all files on your computer get encrypted. And you see the instructions for sending ransom to the hackers.
With exploit kits, hackers do not rely on emails. Instead, they create spoofed emails with malicious code hidden so well that browsers can fail to recognize it. These websites or exploit kits can be more effective in making victims install ransomware. On many websites, such installs are automatic which makes these exploit kits more of a nuisance. Usually, these websites are fake and some elements can make you feel that something is off.
A major similarity in exploit kits is that they direct you to another site. Usually, the redirected address is where the malicious applications are. So, that’s your first red flag. But if you land on one of these sites, the exploit kit explores your browser and browser-based applications for vulnerabilities. If the exploit kit finds a vulnerability, the attack on your device starts.
How Do Exploit Kits Work?
After finding vulnerabilities in your browser, exploit kits finds a vulnerable host. Then you either receive a file downloader or a malicious program that infects your computer. The file can take effect in exploring files on your device and encrypting them. Once it’s done, you cannot access any files on your device. You receive a notification of the method and amount you have to transfer to the hackers. At this stage, you have to make the distressing decision of whether to lose your data or send the ransom.
Now, cybercriminals ask for ransom payments in their crypto wallets. These payments are harder to track and make it more difficult to find cybercriminals. Therefore, it is best to be on the safer side and not leave any vulnerabilities.
Ways to Protect Your Device
The following are some useful tips to protect you from cyberattacks:
Ensure Your Browser is Up-To-Date
Regardless of what browser you are using, it is important to keep it up-to-date. Older versions of browsers may lack security patches for vulnerabilities. The chances of being a victim of ransomware from exploit kits are greater when your browser does not have the latest version. So, do not delay updates on the browser of your choice.
Update All Applications
The best way to protect your device against cyberattacks is to keep all your applications updated. The developers fix the known vulnerabilities on every new update to keep you safe from such attacks.
Stop Using Old OS Versions
Other than making updates on an application level, you should also ensure that you are using the latest version of Windows. Again, newer versions have fixes against a number of cyberattacks. The first thing you should do is not use Windows which no longer gets security updates. If you are still using Windows 7, consider upgrading to a newer version.
Even with new Windows, you should not delay the security updates. In this way, your device will have better defenses against malicious software.
Do Not Click on Shady Links
Whether you receive shady links in the email or you see them on websites, do not click on them. Clicking on such links can lead you to fake websites filled with malicious software. If something about a website does not look right, quickly close it.
Beware of Redirects
Often exploit kits use compromised sites to redirect traffic to exploit kits. Close such sites as soon as you can. An indicator of such websites is the fact that they are full of clickbait ads. So, be careful of such sites and close them on time.
Conclusion
Exploit kits can be hard to detect for human eyes and sometimes for browsers as well. Keep your software updated to the latest versions and be on the lookout for anything fishy. In this way, you can avoid falling into hackers’ traps.
