What is "MailCach Bitcoin Earning"?
During our inspection of the MailCach site, we uncovered that it is a scam website offering to earn Bitcoins. We also discovered that scammers promote this scam via email. The purpose of the MailCach Bitcoin Earning scam is to steal money from unsuspecting individuals. This and similar scams should be ignored.
"MailCach Bitcoin Earning" in detail
The deceptive email promoting this scam claims that the recipient's account has been credited through a "bonus collection service" and that all earned money will be fully disbursed. It urges the recipient to sign in to access the service and emphasizes that doing so will ensure prompt payment of the remaining balance.
The email has an attachment that instructs users to open a website offering to "start earning Bitcoin". This site promotes a service called "MailCach" and claims that users can earn 0.2 Bitcoins per day by connecting their devices to its system for automatic email delivery. It encourages users to run a program that supposedly generates income effortlessly.
Upon clicking the provided "START EARNING BITCOIN" button, a pop-up with the supposed Bitcoin balance and instructions on how to claim coins appears. Eventually, the site requests users to provide a Bitcoin wallet and email address and then pay a service fee to receive a payout.
The ultimate goal is to trick users into believing that they will receive Bitcoins after making a relatively small payment. However, victims never receive the promised cryptocurrency or any other rewards. Therefore, is is highly advisable to be skeptical when receiving emails (or landing on sites) offering prizes, rewards, investment opportunities, etc.

Similar scams in general
These scams prey on users by presenting false promises of receiving Bitcoins or other cryptocurrency. By urging users to provide personal details and pay a fee, they aim to exploit their trust without delivering the promised rewards. Users should remain cautious of such unsolicited emails and websites and avoid any interaction with offers that seem too good to be true.

How did I open a scam website?
The scam we reviewed is spread through fraudulent emails with attachments leading to a deceptive website. Users may also come across scam pages via misleading ads, pop-ups, or links on untrustworthy websites. Interacting with notifications from dubious sites can also lead users to scams.
In other cases, fraudsters utilize rogue advertising networks (often used by torrent platforms, illegal streaming sites, and similar pages) or fake social media accounts and adware to promote their scams. Typically, users are deceived into accessing these scam sites rather than visiting them intentionally.
How to avoid visiting scam pages?
Do not open files or links in irrelevant, unexpected, or similar emails from unknown senders. Download apps and files from official websites or app stores (and avoid using other sources). Do not interact with pop-ups, ads, links, and similar content on shady web pages, and do not permit such web pages to send you notifications.
Regularly update the operating system and installed programs. Use a reliable security tool (antivirus or anti-malware software). If your computer is already infected with unwanted apps, 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.
