What is Keona Clipper?

Keona is the name of a clipper-type malware. Otherwise known as clipboard hijackers, these malicious programs are designed to replace the data copied into the clipboard (copy-paste buffer). Clippers are almost exclusively used to change copied cryptocurrency wallet addresses - in order to redirect outgoing transfers into the cyber criminals' cryptowallets.

Keona Clipper malware overview

According to Keona Clipper's promotional material, it is incredibly lightweight - 20kb in size. This factor aids in the malware's distribution and complicates its detection (e.g., victims are more likely to take note of suspicious programs that occupy a lot of space, use up a significant amount of system resources, or seriously diminish computer performance).

Keona Clipper operates by detecting when users copy a cryptocurrency wallet address into their clipboard. The copied content is then replaced with the address of a wallet in possession of the cyber criminals. So when victims make an outgoing transaction and paste the intended address - one belonging to the criminals is pasted instead. Therefore, the funds are transferred to the cyber criminals, and victims experience a financial loss.

If you suspect that your system is infected with Keona Clipper (or other malware), we strongly advise using an anti-virus to eliminate it without delay.

Clipper examples

We have analyzed thousands of malicious programs; AllcomeFrost, and Zenon are just a few examples of clippers.

It is pertinent to mention that malicious software can have varied abilities in different combinations, and the developers often update their programs with improved or additional functionalities. Therefore, the threats posed by malware can be extensive.

How did Keona Clipper infiltrate my computer?

Since Keona Clipper is offered for sale online, how it is distributed depends on the cyber criminals using it. In general, malware is proliferated using phishing and social engineering tactics. Malicious programs are typically presented as or bundled with ordinary software/media.

Virulent files can be in various formats, e.g., archives, executables, Microsoft Office and PDF documents, JavaScript, etc. Once an infectious file is executed, run, or otherwise opened - the infection chain is jumpstarted.

The most common distribution methods include: drive-by (stealthy ad deceptive) downloads, malicious attachments in spam emails and messages, untrustworthy download sources (e.g., unofficial and freeware sites, P2P sharing networks, etc.), online scams, illegal program activation tools ("cracks"), and fake updates.

How to avoid installation of malware?

We strongly recommend downloading only from official and verified channels. Additionally, all programs must be activated and updated with tools provided by legitimate developers, since illegal software activation tools ("cracks") and fake updaters can contain malware.

We advise against opening the attachments and links found in dubious/irrelevant emails and messages - as that can lead to a system infection.

It is paramount to have a reputable anti-virus installed and kept up-to-date. Security programs must be used to run regular system scans and to remove detected threats and issues. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Delete malware in Autoruns

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer.

To keep your computer safe, install the latest operating system updates and use antivirus software. To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
