What is Scareware? How It Works, Prevention & Examples

Scareware has become one of the rapidly growing threats in the ever-changing world of cybersecurity, a very malicious tactic with the intent to evoke a sense of fear and tension in the unsuspecting user. As cyber-thieves become more demanding, scareware has provided an avenue through which they are able to play with their victim’s psychology, victimized by their belief that their devices had been compromised, hence acting rashly. Such malicious tactics can lead to financial loss, theft of your information, or the download and installation of more malware.

According to the FBI’s IC3: Tech support frauds accounted for a $54 million loss in 2019. The number of complaints filed in the US was 13,633. The report by IC3 also shows that in the same year, scareware attacks incurred losses of $2,009,119. Now that these types of attacks are gaining momentum, it becomes crucial that you recognize this threat and how it works, as well as the steps you can take to ensure your safety and protection for yourself and your organization. Education on the signs of scareware and best practices will protect both individuals and businesses from the ravaging repercussions of this rapidly growing cybersecurity threat.

This article delves into the intricacies of scareware, explaining how it works, its impact on systems, and the best practices for prevention and removal. We will also explore real-world scareware examples and how cybersecurity tools, like those from SentinelOne, help in defending against these threats.

What is Scareware?

Scareware, in short, is some form of malicious software designed to trick the user into thinking that a computer is invaded by viruses or other forms of malware. It usually masquerades as false security alerts, pop-ups, or messages that insist that something needs to be done immediately. Technically, the scareware doesn’t solve any kind of problem but just tries to collect ransom, steal private information, or install additional malware.

The primary tactic underlying all these kinds of scareware is fear-mongering. The threat actors do their best to take advantage of a user’s concern for the security of their device, convincing them that they are in need of paying for services they do not necessarily need or want.

Impact of Scareware

Scareware causes much upheaval in the personal and business systems, ranging from financial to an overall degradation of performance and security. Scareware makes money by gaining the trust of users through false assertions, stopping normal operations to more heinous security breaches unless addressed. Here are some of the impacts scareware can have:

• Monetary Loss: The first goal of scareware is that victims pay for a fake application or service. These cyber fraudsters achieve this by providing false security alerts to users and claiming that their computers are infested in order to induce them into paying for “repairs” that are not necessary. Sometimes, users pay for recurring charges or subscription services.
• System Performance Issues: Once installed, scareware will generally bring the system performance down considerably. The malware tends to run in the background secretly, latching onto your computer’s CPU and memory to weigh it down with slowdowns, freezes, and crashes. Endless pop-up warnings and fake alerts are some of the problems users face when running such computers.
• Data Theft: Some scareware goes beyond mere annoyance and enters the cyber-espionage world. Some scareware applications are designed to collect sensitive personal information such as credit card information, checking account information, login details, and more. The data is then sold on the dark web or used to steal identities and carry out fraudulent activities.
• Further Infections: At some point, the scareware may ultimately prove to be a portal for more vicious malware. Once installed, the scareware could be an open door to other malware, such as trojans, keyloggers, or ransomware, which may easily breach the network. Thus, a minor scareware attack can mushroom into full-scale security problems with far devastating financial and operational costs.

Difference Between Scareware, Ransomware, and Adware

Scareware, ransomware, and adware are not very different in how they present themselves to portray their relationship with the user; however, the threats and attack styles of these malware differ sharply. In order to effectively classify and deal with each type, these differences are highly important to be known:

• Scareware: Scareware is a variety of malware that has the intention to deceive victims to buy or download fake software using demagogic means, such as antivirus programs or system optimization tools, through psychological manipulation, like creating alarming pop-ups and security alerts declaring that the system is infected with malware. In contrast to ransomware, scareware does not encrypt files or block the system’s access. Instead of fear tactics trying to scare the victim into making unconsidered decisions, it usually works on financial grounds, but scareware may leave open gates for more harmful infections.
• Ransomware: Ransomware is much more aggressive malware. It locks users out of their devices or encrypts critical files, making the system unusable until a ransom is paid. The main purpose of ransomware is extortion, as it requires the payment of money, mostly in cryptocurrency for the restoration of access to the compromised data system. Where scareware fools users into making unnecessary buys, ransomware blackmails them with the permanent loss threat if ransom demands are not met. Usually, the stakes are much higher in ransomware attacks, crippling whole businesses or organizations.
• Adware: Although seemingly innocuous compared to the other two forms, adware is annoying and a security risk nonetheless. The attacker makes money off of the user by bombarding them with unwanted ads either through the browser or pop-ups. Not inherently malicious, adware can bring down system performance, disturb the browsing experience, and sometimes track user behavior for targeted advertising. This can lead to privacy-related problems, and in some types of adware, it may even invite the arrival of a more malicious program if not removed quickly.

How Does Scareware Work?

The scareware tactics play on the fear of the user by using their concern for security about any device. It uses psychological tactics to activate the quickest reaction from the users. Here’s how it works, step by step:

• Initiation: Scareware is normally introduced through different deceitful means, such as fake websites, misleading advertisements, or phishing emails. Users may stumble upon apparently legitimate or attractive links that will prompt them to click and inadvertently set the scareware in motion. Once this is done, the malware attacks the user’s mind.
• Fake Warning: As soon as this malware gets installed and activated, it starts generating strings of pop-ups or alert messages that look as realistic as authentic antivirus software. Such alerts normally state that your machine is infested with malware or viruses as well as scary messages that are intended to scare the user by provoking fear and anxiety. The design is generally graphics that look professional in appearance to make the threat look authentic. This is probably the most critical step as scareware operations largely rely on the element of fear and a sense of urgency.
• Call to Action: Scareware will ask the user to do something soon, usually to download a utility or pay for a purported fix -all of this often within a deadline. Messages are worded in an urgent and alarming style, using techniques that create on the part of the user a sense of urgency to act right now to rescue the device from impending doom.
• Payment: Once the scareware has extorted the user to pay, they then end up paying for a service that has no value and which will not in any way rectify their problem. This may install further malware that may enhance the security risk. In the end, the user ends up losing money and system damage.

How to Identify Scareware Attacks

Scareware can be very difficult to identify at first glance because it looks almost the same as legitimate antivirus pop-up alerts and security warnings. However, there are clear signs that help users distinguish the real security notification from scareware. Distinguishing between these signs is therefore imperative in aversion to the manipulative tactics scareware brings. Here are some key indicators:

• Frequent Pop-Ups: One of the most common signs of scareware is an overwhelming number of pop-ups and alerts that constantly interrupt your browsing or system activity. These pop-ups often claim that your device is infected with viruses or malware, pressuring you to take action immediately. Legitimate antivirus software will rarely bombard you with continuous alerts, especially outside of normal scans.
• Spelling or Grammar Mistakes: Scareware is often constructed poorly, containing obvious spelling or grammar mistakes. This is a red flag because legitimate security software is always developed by a professional company that knows its warnings are polished and error-free. Any awkward phrasing or glaring errors are great indicators that the warning is fake.
• Requests for Immediate Payment: Legitimate antivirus software rarely demands immediate payment through pop-ups, especially in a high-pressure manner. Scareware often tells the user to ‘buy it today’ because if not, the user’s computer remains open to full exploits unless action is taken immediately. Reliable security software companies usually get their up-front prices out in the open without threatening you into some immediate buying action.
• Over-the-Top Urgency: Scareware thrives on urgency and fear. Alerts that claim your device is in immediate, extreme danger or use superfluous language like “Your computer is at risk! Act NOW!” are likely scareware. Genuine security software does not deploy aggressive or panic-inducing language and allows enough time for users to pursue security concerns calmly.

How to Prevent Scareware (Best Practices)?

To protect oneself against scareware, one needs an active approach combining awareness with good cybersecurity best practices. The best practices below will help reduce the risks of attacks that may develop from scareware:

• Use Trusted Security Software: The most effective way to guard against scareware is to install reputable antivirus and antispyware/antimalware. Look for a high score in customer reviews and some history of effective protection. Install and update them regularly as they produce updates regularly to combat emerging threats. Such a security suite will catch and block the scareware that might not have reached your system at all.
• Avoid Clicking on Suspicious Links: No matter how flashy those spam emails or emails from unknown addresses are, do not click on anything before hovering over any link. Most of the time, scareware comes through fake ads and unfamiliar websites, and you should not open anything suspicious. The better rule of thumb would be to be afraid of anything that appears too good to be true or incorrect and not dig yourself into a hole that might erupt at any time.
• Keep Your Software Updated: Critical risks occur for those who fail to frequently update their operating system, web browsers, and all the rest of the installed software. Software updates typically include patches related to identified vulnerabilities, which cybercriminals may exploit. Enable automatic updates whenever that feature is available so you can have the most recent security features and fixes.
• Educate Yourself and Your Employees: The best defense against scareware is awareness. Take the time to educate yourself as well as your employees about common scareware tactics and empower them to recognize threats. Conduct training on how to identify scareware, the need to be skeptical when confronted with alarming alerts, and the best reporting practices for suspicious activity.
• Block Pop-Ups and Ads: Use the pop-up blockers and ad filters in your browser’s settings, to block scareware from showing you fake alerts. All modern browsers come with this ability and there are tens of thousands of extensions to enhance it. By reducing the number of invasive ads and popups, you reduce the number of opportunities through which the scareware has a chance to take you off guard.

Steps to Take if You’ve Been Targeted by Scareware

If you suspect that you’ve been targeted by scareware, it’s crucial to act quickly and methodically to minimize potential damage and safeguard your data. Scareware is designed to capitalize on emotion, working on your response to prompt you into making a frantic choice that will result in financial loss or further system compromise.

Knowing the steps helps you handle the situation better and regain control over your device. Here is what you should do:

1. Do Not Click on the Alert: No matter how serious or believable the scareware alert might sound, you should not click on anything it is presenting. Some links and buttons may install more malware on the computer or launch more attacks on personal information. The best first line of defense is always to ignore and avoid the pop-up.
2. Close the Browser or Program: If the scareware infected you while you were browsing, close your browser instantly. To force quit a browser that will not close, use Task Manager (on Windows) or Force Quit (on Mac). This stops the scareware from spreading through further pop-ups or malicious downloads.
3. Run a Full Antivirus Scan: Once you’ve closed the suspicious alert or program, run a full scan with your trusted antivirus or antimalware software. A comprehensive scan will help detect and remove any malicious files that may have infiltrated your system. Make sure your antivirus software is up to date with the latest virus definitions to maximize its effectiveness.
4. Clear Your Browser Cache: Sometimes, scareware can leave traces in the cache of your browser, which might trigger it to appear once more when you open your browser. Remove all the history, cookies, and cache from your browser to get rid of the bad leftovers of scareware. This will reduce your possibility of encountering such malicious pop-ups again in the future.
5. Monitor Bank Statements: If, during this scareware attack, you’ve submitted payment information or signed up for a service, be sure to keep an eye out for something suspicious in your bank accounts. Inform your bank or credit card company of any suspicious activity right away to avoid additional loss and shut down further transactions.
6. Consult a Professional: If you have no idea what to do, or the scareware has destroyed your system this much, it’s high time to involve a cybersecurity professional or your IT support team. They could provide more specialized input in scanning deeper, system recovery, and also advice on how to prevent attacks like this in the future. Professional help is needed, especially if serious infections spread due to the scareware or when private information is compromised.

Popular Scareware Examples

Scareware exists in various forms. It employs unscrupulous methods to dupe users into paying for false software or services. Listed below are the most popular examples of real-world scareware that have come into prominence:

• Rogue Antivirus (AV) Products: Rogue AV products are one of the most common forms of scareware. Such applications pretend to be other security software and do not provide any protection or service. Instead, it uses users’ fear of malware by pretending to “clean” systems for them. In most cases, cybercrooks design such rogue products to appear and feel exactly like trusted AV brands and use their logos and interfaces to install credibility. Traditionally, malware packages designed to portray themselves as fake antivirus products produce spurious pop-ups or messages claiming that your computer is infected with viruses, spyware, and the like.
• MacDefender: This was an especially targeted version for Mac users who experienced a scareware application that would display pop-up warnings about supposed malware infections on their Apple devices. Various messages were sent to users, indicating that their computers were infected with various threats. Users were asked to download the supposed cure to eliminate the threats. Apart from extorting money from its users, this malware would inject other malware products into the invaded systems, hence giving the malware a double threat. Apple later implemented security measures that secured it from future threats of the same nature.
• WinFixer: This is possibly the most notorious scareware brand under which a targeted user would believe that his computer is filled with errors and infections. It normally gets to computers through scam websites or pop-up ads. After installation, it continues popping up messages relating to problems like viruses or even other faults in the system to frighten its victim further. The software carries out a so-called “system scan,” in which it returns false reports of infections or faults in the system. This is where it will rely on the victim’s lack of technical understanding to get away with its claims. It then convinces users to buy a “full version” of WinFixer to solve these supposedly created problems.
