Trickbot is a banking-trojan that steals the login credentials for targeted banking sites.
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 detection database 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 Trickbot trojan tries to steal the login credentials for specific banks in specific countries, with the list of targeted banks changing regularly. More information about Trickbot's latest targets can be found at:
The operators behind the Trickbot trojan usually distribute the malware as an file attached to spam email messages. As with most such messages, the content of the email is designed to look legitimate so that the user is lured into opening the attachment. Doing so runs a script embedded in it, which then downloads the Trickbot trojan from a remote server, installs and runs it on the computer.
More rarely, Trickbot may be delivered as the payload of an exploit kit. In that case, the trojan itself is silently dropped, installed and run on the affected machine.
The Trickbot trojan can use either of two techniques to trick the user into unwittingly giving away their login credentials.
The first technique (known as static injection) involves replacing the banking site's legitimate login page with a fake one that looks almost exactly like it. The second technique (known as dynamic injection) redirects the web browser to a server under the trojan's operator's control whenever the user enters the URLs for the targeted banking sites.
In either case, if the user enters their login details on the fake page, the information is captured and sent to the operators. The stolen data may then be used to commit financial fraud.
