What is KopiLuwak?

KopiLuwak is a backdoor infection that can be used by multiple third parties to access a target system. Whatever happens to the affected system later depends on the criminals who employ this backdoor. In other words, if you remove KopiLuwak, you also have to make sure that you terminate all the other malicious infections that could have entered the target system because of this backdoor. Also, you can find the manual removal instructions at the bottom of this entry, but it would be for the best to invest in a legitimate antispyware program that would delete KopiLuwak for you automatically.

Where does KopiLuwak come from?

KopiLuwak is associated with an already existing backdoor that is called JS/KopiLuwak. This new version of this backdoor is used by a Russian-speaking actor Turla. Usually, these backdoors are used as reconnaissance tools, and whatever happens to the target system, later on, depends on what this backdoor finds on it.

It is important to note that this backdoor doesn’t get distributed at random. It usually comes with spear-phishing attacks, where the criminals target government institutions by sending them spam emails. Here, it is important to note that most of the time, backdoors, Trojans, and other similar infections could be avoided if users were more careful about the emails they open every single day.

The problem here is that it might be hard to remain alert when you have to open multiple emails all the time. What’s more, spear-phishing emails often look like legitimate notifications from reliable sources. They come with attachments that look like real documents. For instance, the attachments that carry KopiLuwak look like .Doc files, and when users download and open these files, they are urged to “enable content” in order to read the document. Of course, by enabling that content, they actually enable Macros that allow the infection to connect to the remote server and perform various actions.

Computer security experts suggest that whoever makes use of KopiLuwak, they might be interested in the G20’s Digital Economy Task Force. So, people who have access to sensitive information should be very careful about interacting with unfamiliar content. Some suggest that even journalists could get infected with KopiLuwak.

What does KopiLuwak do?

When this infection enters a target system, it employs compromised websites as its C2 (command and control) servers. So it means that the backdoor can communicate with the people responsible for this infection behind the user’s back.

This infection installs itself in one of the following directories: %LocalAppData% \Microsoft, %LocalAppData%\Temp or %USERPROFILE%\Application Data. Thus, it shouldn’t be hard to remove this backdoor if you know where to look for its files.

Research shows that the newest version of KopiLuwak can even download files from the C2 and save them on the infected system. It can also transfer collected information from the system back to its C2. As mentioned, this infection cannot do much on its own, as it is mostly used as a reconnaissance tool. So it means that this infection is just a start.

At the same time, if you manage to remove it before other dangerous infections enter your system; it doesn’t mean that you are safe. You should definitely run a full system scan with a powerful antispyware tool. It would also be a good idea to change all of your passwords. Consider employing a password manager that would help you generate strong and unique passwords. If necessary, address a cybersecurity specialist who would provide you with an indebt consultation on the issue.
