The target: Bengal cat lovers in Australia
When it comes to cyberattacks, hackers often choose broad targets to maximize impact or target critical industries like banks or hospitals where there is a large amount of specific data to steal.
However, what makes this attack so peculiar is its focus on a very specific niche: Bengal cat lovers living in Australia who are interested in knowing whether these animals are allowed there.
Imagine you, an exotic cat lover, are searching for information about the legality of Bengal cats in Australia. When you click on one of the first results, you are taken to a cat forum page, where a link invites you to download a file to learn more about the subject.
Sounds legit, right? Unfortunately, when you click, you end up downloading a hidden JavaScript file designed to infect your device with malware called Gootloader.
What is Gootloader and how does it work?
Gootloader is a well-known piece of malware in the cybersecurity world. It has been around for over a decade and has been associated with the REvil ransomware group, which is responsible for massive attacks in various parts of the world.
This malware is stealthy and powerful, allowing attackers to remotely control an infected device. With this, they can access your data, steal banking information, or even lock you out of your system, demanding a ransom to release it.
In the case of Bengal cat lovers, the Gootloader was implanted using a technique of SEO poisoning . Simply put, hackers manipulated search results so that the malicious forum link appears at the top of searches.
This way, anyone searching for “Are Bengal cats legal in Australia?” would end up clicking on a link designed to infect their device.
SEO Poisoning: The Technique Behind the Attack
For a hacker, to provide A search term is an effective way to lure victims to seemingly confidential pages that are actually ready to deploy malware. This technique is often used for popular searches or in targeted attacks on specific institutions. However, in this case, the cybercriminals chose a rather unusual search term.
This choice has led to a few theories. Perhaps the attack was a test to see how effective SEO poisoning can be on a smaller scale, without attracting too much attention. By targeting such a specific search, the hackers were able to gauge the success of the technique without alerting most users or raising suspicions.
Another possibility is that the attack was a way to target a specific target. Perhaps someone with access to valuable information or an insider's network had an interest in Bengal cats.

Given this very specific attack, you may be wondering: how can you avoid falling into traps like this? Here are some practical tips to help you stay safe while browsing the internet:

3. Avoid downloads from untrusted sources
In the case of the attack discovered by SOPHOS, the malware was installed via a disguised download from a forum. As a general rule, never download files from unknown websites and check the reliability of the sources. Cybercriminals often disguise malware as legitimate documents, images or files to trick users.
