Scareware is a deceptive form of malicious software (malware) that manipulates users using fear and anxiety. The scareware definition includes any program that uses psychological tactics to trick users into purchasing unnecessary software or downloading harmful programs. This cyber threat typically appears in the form of alarming pop-up advertisements or fake security alerts, claiming that a user's device is infected with viruses or that there is some other real, imminent danger.
Falling victim to scareware can have severe implications. Even if the scareware itself doesn't contain harmful code, it can lead to unnecessary expenses for ineffective or non-existent services. Also, users may install malicious software that compromises their system's security, potentially leading to data theft, financial losses, or further malware infections. Clearly understanding the definition of scareware, as well as its characteristics and nuances, can help users take the necessary measures to protect themselves.
Scareware relies on exploiting human psychology, particularly fear and urgency, manipulating users into taking actions that benefit cybercriminals. Typically, an attack begins with a pop-up or alert that appears suddenly on a user's screen. These messages might seem like legitimate security warnings to an untrained eye, as they claim that the device is infected with viruses or that personal data is at risk. The scareware sometimes presents itself as a free virus scan. Inevitably, the scan “detects” numerous threats.
To seem more credible, scam antivirus software might use official-looking logos or terminology that copies genuine security products. The alarming messages can create panic, pushing users to act quickly without proper consideration. Once the user is sufficiently frightened, the scareware presents a solution – usually in the form of software to download or a service to purchase.
Clicking on a link or button within the scareware message can lead to several outcomes you should be aware of:
Scareware attacks can have consequences that go way beyond the initial deception. The immediate impact might seem limited (unnecessary software purchases or downloads), but in reality, the long-term effects can be severe and varied.
For individuals, the financial toll can be significant. Victims may find themselves paying for useless software that does not resolve the issue or, worse, facing unauthorized charges on their credit cards due to identity theft. Also, the psychological impact shouldn't be underestimated, as these attacks can lead to increased anxiety about online activities and erode trust in legitimate security measures.
For organizations, a successful scareware attack can be a gateway for more severe security breaches. If an employee falls for a scam, it could potentially compromise the entire corporate network, leading to data breaches exposing sensitive information. The ripple effects of a scareware attack on a company's reputation can be devastating. Additionally, regulatory bodies might impose hefty fines for failing to adequately protect against such cyber security threats.
Scareware has a long history in the cybercrime field, with high-profile examples that mirror its evolution. One of the earliest and most notorious campaigns was the “SpySheriff” incident in the mid-2000s. This scam antivirus software would display fake alerts about non-existent threats, pressuring users to purchase the full version to “clean” their systems.
In 2010, a more sophisticated scareware attack targeted users of the Minneapolis Star Tribune website. Visitors were shown malicious ads that redirected them to fake antivirus scans, ultimately tricking them into paying for useless software. This campaign netted the cybercriminals approximately $250,000 before being shut down. The perpetrator, Peteris Sahurovs, was arrested in 2018.
More recently, the “Tech Support Scam” has become prevalent. In this variation, pop-ups claim that the user's computer is infected and provide a phone number for “Microsoft Support.” Unsuspecting victims who call are then manipulated into granting remote access to their computers or purchasing unnecessary services.
Recently, Restoro and Reimage, two companies that operated a tech support scam using scareware tactics, were fined $26 million by the US Federal Trade Commission (FTC) for their actions in 2018. The companies used fake Microsoft Windows pop-ups to scare users into believing their computers were infected with malware. The scan would inevitably claim to find performance or security issues that required urgent repair, prompting users to purchase software from the perpetrators.
Mobile platforms have not been immune either. The Android Defender scam, for instance, imitated legitimate antivirus apps but actually locked users out of their devices until they paid a “fine.”
In conclusion, being just scared by a type of malware might seem like a minor nuisance, but it is far from it. Scareware tactics have adapted over time, and the severity of these attacks is reflected in the response from law enforcement agencies, with significant fines and even international arrests. For example, in July 2023, Spanish police arrested a Ukrainian citizen who had been on the run from US authorities for over ten years for his involvement in a large-scale scam that caused huge losses to consumers worldwide – over $70 million.
Recognizing scareware attacks is your most important ally in maintaining robust cyber security. Here are the main indicators to help you identify potential attacks:
1. Unfamiliar software names. Scareware frequently masquerades as antivirus programs with names that include words such as “Antivirus” or “Defender.” Always research security software before downloading.
2. Pressure tactics. Scareware often uses urgent language, countdown timers, or threats of imminent danger to rush your decision-making.
3. Requests for personal information. Genuine security software won't ask for credit card details or other sensitive information through pop-ups.
4. Unsolicited scans. Be suspicious of any virus or malware scan you didn't initiate, especially if it finds multiple severe threats.
5. Limited interactivity. Often, all buttons (including “close” or “cancel”) in a pop-up lead to the same outcome, limiting your ability to get rid of it.
6. System slowdowns. When your device suddenly becomes sluggish alongside other warnings in this list, that is a good indication that a scareware attack is in progress.
7. Spelling and grammatical errors. Many messages contain obvious language mistakes, a red flag for illegitimacy. However, with the recent advances in AI, these errors will drop in frequency.
If you suspect your device is infected with scareware, take immediate action to remove it and protect yourself from future attacks:
1. Disconnect from the internet so that further damage or data theft is prevented.
2. Enter safe mode on your device to limit the malware's functionality.
3. Use legitimate, up-to-date antimalware software to perform a full system scan. This can help detect and remove the scareware.
4. Manually uninstall any suspicious programs you don't recognize from your list of installed applications.
5. Clear your browser cache; reset browser settings to remove any lingering traces of the malware.
To prevent future scareware attacks:
While no single security measure is foolproof, scareware attacks can be largely prevented through a combination of proactive strategies and user vigilance. Here are key measures:
For Individuals
1. Use robust cybersecurity solutions. Install comprehensive, up-to-date antivirus and antimalware software that includes real-time protection against emerging threats.
2. Keep software updated. Make timely updates to your operating system, browsers, and applications to patch vulnerabilities that scareware might exploit.
3. Practice safe browsing. Enable pop-up blockers, avoid clicking on suspicious links, and be cautious with email attachments. Use ad-blockers to prevent malicious advertisements.

Yes, scareware can affect mobile devices. While app stores like Google Play and Apple's App Store have stringent security measures, scareware can still find its way onto mobile devices through third-party app stores, malicious websites, or phishing links.
Some variants might also disguise themselves as legitimate apps and bypass initial security checks. Users can protect themselves by downloading apps only from trusted sources and keeping their devices updated.
Yes, legitimate security programs or system maintenance tools can sometimes be mistaken for scareware due to their alarming notifications or aggressive marketing tactics. These programs often use strong language to urge users to take immediate action, which can resemble the scare tactics used by scareware. It's important to verify the legitimacy of such programs by checking reviews, sourcing from official app stores, and ensuring they come from reputable developers.
Even reputable companies such as Adobe have been accused of using scareware tactics by promoting misleading “system optimizer” programs alongside their legitimate software updates.
No, scareware is not a virus. It is a type of malicious software designed to to frighten or intimidate users into buying unneeded programs or services by displaying fake security alerts and warnings. While it is deceptive and can cause harm, it does not replicate or spread like a virus.
But although scareware isn’t considered a virus, it is important to know that it could act like one, leading to other forms of malware:
· It can install fake antivirus software that can give users a false sense of security. By not providing legitimate protection against cyber-threats, scareware can leave systems exposed to various types of attacks.
· Some scareware, such as SpySheriff or Windows Defender security warning, has been known to disable legitimate antimalware products, leaving systems vulnerable.
· Scareware can also bundle malware such as keyloggers that can steal passwords and other sensitive data from the victim.
· During the fake scareware registration process, a victim’s credit card details and other personal data may be revealed to attackers.
