Exploit:JS/MagnitudeEK.G identifies JavaScript code that redirects users to malicious webpages hosting the Magnitude exploit kit.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
The JavaScript code identified by the Exploit:JS/MagnitudeEK.G detection essentially acts as a redirector, as it routes users to a malicious page that serves as the landing page for an exploit kit under an attacker's control.
Once the user is on the landing page (which is also identified by the Exploit:JS/MagnitudeEK.G detection), they are exposed to the exploit kit, which is a toolkit used by attackers that can probe the user's computer for specific vulnerabilities in the operating system or installed programs. If any are found, the exploit kit tries to exploit it.
Once an exploit kit successfully exploits a vulnerability, it will launch its payload, which usually involves downloading and installing other malware on the affected machine. The installed malware can be any form of malicious program, but is most often a trojan, backdoor or ransomware.
