Bad Rabbit Attack Scam
Written by Tomas Meskauskas on (updated)
What is Bad Rabbit Attack?
"Bad Rabbit Attack" is a fake error displayed by a rogue website. It is very similar to Code 055BCCAC9FEC, Your Device Is Under Threat, Windows Product Key Expired, and many others.
Research shows that users are often redirected to this website by potentially unwanted programs (PUPs) that infiltrate systems without permission. Furthermore, as well as causing redirects, PUPs deliver intrusive advertisements (pop-ups, banners, coupons, and so on), gather information, and misuse system resources to run unnecessary processes.
The "Bad Rabbit Attack" error states that the system has detected an attack and has been blocked. It also states that confidential information (logins/passwords, banking details, and so on) is at risk. For these reasons, users are encouraged to immediately contact Windows Technical Support via a telephone number ("1-844-539-5778") provided.
These people then supposedly resolve the issues. Bear in mind, however, that, as mentioned above, the "Bad Rabbit Attack" error is fake (rather than a scam). Cyber criminals attempt to scare unsuspecting users and trick them into calling, and paying for technical services that are not required.
Be aware also that developers of fake errors often demand remote access to the caller's PC. Once connected, they stealthily install malware and change system settings. These criminals claim to detect "additional issues" and offer further help for an extra fee. For these reasons, you should ignore "Bad Rabbit Attack" and never call the aforementioned telephone number.
This error can be removed simply by closing the web browser (preferably, via Task Manager) or rebooting the system. Immediately scan the entire system with a legitimate anti-virus/anti-spyware suite. Note that after re-running the web browser, never restore closed tabs, otherwise you will return to the malicious website.
Potentially unwanted programs deliver various intrusive advertisements. To achieve this, they employ various tools that enable placement of third party graphical content on any site. Therefore, intrusive ads often conceal underlying content, thereby diminishing the web browsing experience.
Furthermore, intrusive ads redirect to malicious websites and run scripts that download and install malware or PUPs. Therefore, even a single click might result in high-risk computer infections. Another downside is information tracking. Most PUPs gather information that typically includes personal details.
IP addresses, web URLs visited, queries entered into search engines, keystrokes, geo-locations, and other collected data is typically sold to third parties. These people (potentially, cyber criminals) misuse the data to generate revenue. In doing so, they cause serious privacy issues.
Potentially unwanted programs also misuse system resources to perform unnecessary tasks (e.g., to mine cryptocurrencies). In this way, potentially unwanted programs reduce overall system performance. For these reasons, PUPs must be eliminated immediately.

As mentioned above, "Bad Rabbit Attack" shares many similarities with dozens of other fake errors. All claim that the system is corrupted, however, these claims are merely attempts to extort money from regular users. All potentially unwanted programs share many similarities.
By offering "useful features" (e.g., anti-virus, improved download performance, file conversion, system optimization, etc.), PUPs attempt to give the impression of legitimacy, however, they are designed only to generate revenue for the developers and pose a direct threat to users' privacy and Internet browsing safety.
How did potentially unwanted programs install on my computer?
Some PUPs have official download websites, however, most are distributed using a deceptive marketing method called "bundling", and the aforementioned intrusive ads. Due to lack of knowledge and careless behavior by many users, PUPs often infiltrate systems without permission. "Bundling" is stealth installation of third party apps together with regular software/apps.
Developers do not adequately disclose these installations - they hide "bundled" apps within the "Custom/Advanced" options, or other sections of the download/installation processes. In addition, many users rush these procedures, skip steps, and click advertisements without understanding the consequences. In doing so, they expose their systems to risk of various infections.
How to avoid installation of potentially unwanted applications?
To prevent this situation, pay close attention when browsing the Internet and, especially when downloading/installing software. Be aware that intrusive ads typically look legitimate and useful, however, they are distinguishable, since most lead to gambling, adult dating, pornography, and other dubious sites.
If you encounter these ads, immediately remove all dubious programs/browser plug-ins. Carefully analyze each window of the download/installation dialogs and opt-out of all additionally-included programs. The key to computer safety is caution.
