What is SushiSwap scam?

Our team has discovered a fake SushiSwap app download page while examining other shady websites and deceptive ads. Sushi is a legitimate decentralized cryptocurrency exchange built on Ethereum. After launching the installer downloaded from the fake SushiSwap, we learned that it installs a Remote Access/Administration Tool (RAT) called Remcos.

SushiSwap scam in detail

We have analyzed the fake SushiSwap page and found that it looks almost exactly the same as the official one (it has the website design, text, icons, and so on), but it has a different URL address. After clicking the "Download App" button (which is "Enter App" on the legitimate page), this page downloads the "SushiSwap-dApp-3.1.0-installer.exe" file (its name may vary).

The executable file downloaded from this page installs Remcos - a legitimate RAT that cybercrimnials can misuse to steal sensitive information, infect a computer with malware, take screenshots, and other purposes.

They get opened after clicking on fake download buttons, visiting torrent sites, illegal movie streaming pages, etc., or clicking on an Internet search engine result.

How to avoid visiting scam pages?

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.
