What kind of scam is "Double Your Bitcoins"?

Criminals behind this scam website attempt to trick visitors into transferring a sum of Bitcoins to them by offering to return ten times the amount to the provided BTC wallet address. Websites of this type (money-swindling schemes) should never be trusted.

Double Your Bitcoins scam

"Double Your Bitcoins" scam overview

Cyber criminals behind this scam claim that they will deliver 1 - 100 BTC to people who send 0.1 - 10 BTC to the provided BTC wallet address. In summary, they offer to make an investment that generates a return of ten times the amount of the initial investment.

It is stated that this is just a one-time offer and, therefore, unsuspecting visitors are more likely to send a larger Bitcoin sum to achieve higher investment returns. As mentioned, these scam websites (and other untrusted pages) are often opened by browsers that have potentially unwanted apps installed.

PUAs are often designed to promote (open) dubious, untrusted websites, serve advertisements, and collect information relating to users' browsing activities and/or other details. PUAs can serve coupons, pop-ups, surveys, banners and other ads. When clicked, these can open dubious, potentially malicious pages or run scripts designed to download and install other PUAs.

These apps can also record information such as IP addresses, geolocations, URLs of visited websites, entered search queries, etc. In some cases, they can collect sensitive data. The recorded information could be sold to third parties (potentially, cyber criminals) or misused to generate revenue in other ways.

Online scams in general

Some examples of other scam websites are "Social Network Hacks Scam" and "Gift Card Giveaway Scam". Generally, scammers behind these web pages attempt to deceive visitors into transferring money and/or providing sensitive information (e.g., credit card details, login credentials), which could be misused to generate revenue in various ways.

Browsers often open these web pages when PUAs are installed.

How did potentially unwanted applications install on my computer?

PUAs are commonly distributed by integrating them into the download and/or installation set-ups of other programs, so that a proportion of users inadvertently download and install them together with their chosen software. This distribution method is known as "bundling".

Offers to download and install additionally-included apps usually appear in "Advanced", "Custom" and other settings of the set-ups (where they can usually be declined). Many users fail to check and change these settings, thereby granting permission for PUAs to be downloaded and installed by default.

In addition, unwanted downloads and installations are sometimes caused by clicking deceptive advertisements capable of executing certain scripts.

How to avoid installation of potentially unwanted applications

Download and installation tools, sources, such as third party downloaders, installers, Peer-to-Peer networks (e.g, torrent clients, eMule), unofficial websites can be used to distribute PUAs or even malware. Therefore, software and files should be downloaded only from official pages and through direct links.

Check all "Advanced", "Custom" and other settings, and decline offers to download or install additionally-included, unwanted applications. Do not click advertisements that are displayed on dubious websites, since they can open other untrusted websites or cause unwanted downloads and installations.

Remove any, suspicious extensions, add-ons, and plug-ins already installed on the browser. Software of this kind that is installed on the operating system should also be uninstalled. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.

How to identify a pop-up scam?

Pop-up windows with various fake messages are a common type of lures cybercriminals use. They collect sensitive personal data, trick Internet users into calling fake tech support numbers, subscribe to useless online services, invest in shady cryptocurrency schemes, etc.

While in the majority of cases these pop-ups don't infect users' devices with malware, they can cause direct monetary loss or could result in identity theft.

Cybercriminals strive to create their rogue pop-up windows to look trustworthy, however, scams typically have the following characteristics:

  • Spelling mistakes and non-professional images - Closely inspect the information displayed in a pop-up. Spelling mistakes and unprofessional images could be a sign of a scam.
  • Sense of urgency - Countdown timer with a couple of minutes on it, asking you to enter your personal information or subscribe to some online service.
  • Statements that you won something - If you haven't participated in a lottery, online competition, etc., and you see a pop-up window stating that you won.
  • Computer or mobile device scan - A pop-up window that scans your device and informs of detected issues - is undoubtedly a scam; webpages cannot perform such actions.
  • Exclusivity - Pop-up windows stating that only you are given secret access to a financial scheme that can quickly make you rich.

How do pop-up scams work?

Cybercriminals and deceptive marketers usually use various advertising networks, search engine poisoning techniques, and shady websites to generate traffic to their pop-ups. Users land on their online lures after clicking on fake download buttons, using a torrent website, or simply clicking on an Internet search engine result.

Based on users' location and device information, they are presented with a scam pop-up. Lures presented in such pop-ups range from get-rich-quick schemes to fake virus scans.

How to remove fake pop-ups?

In most cases, pop-up scams do not infect users' devices with malware. If you encountered a scam pop-up, simply closing it should be enough. In some cases scam, pop-ups may be hard to close; in such cases - close your Internet browser and restart it.

In extremely rare cases, you might need to reset your Internet browser. For this, use our instructions explaining how to reset Internet browser settings.

How to prevent fake pop-ups?

To prevent seeing pop-up scams, you should visit only reputable websites. Torrent, Crack, free online movie streaming, YouTube video download, and other websites of similar reputation commonly redirect Internet users to pop-up scams.

To minimize the risk of encountering pop-up scams, you should keep your Internet browsers up-to-date and use reputable anti-malware application. For this purpose, we recommend Combo Cleaner Antivirus for Windows.

What to do if you fell for a pop-up scam?

This depends on the type of scam that you fell for. Most commonly, pop-up scams try to trick users into sending money, giving away personal information, or giving access to one's device.

  • If you sent money to scammers: You should contact your financial institution and explain that you were scammed. If informed promptly, there's a chance to get your money back.
  • If you gave away your personal information: You should change your passwords and enable two-factor authentication in all online services that you use. Visit Federal Trade Commission to report identity theft and get personalized recovery steps.
  • If you let scammers connect to your device: You should scan your computer with reputable anti-malware (we recommend Combo Cleaner Antivirus for Windows) - cyber criminals could have planted trojans, keyloggers, and other malware, don't use your computer until removing possible threats.
  • Help other Internet users: report Internet scams to Federal Trade Commission.
