What is the fake "Claim Sign" website?
Our researchers discovered this fake "Claim Sign" page (claim.signcommunity[.]link; possibly other domains) during a routine investigation. This webpage masquerades as the Sign Protocol website (sign.global). It lures victims into exposing their digital wallets to a cryptocurrency drainer by implying that eligible users can receive rewards.
IMPORTANT NOTE: We do not review crypto projects, please do your own research when investing money.
Federal Trade Comission (FTC) states that since the start of 2021, more than 46,000 people have reported losing over $1 billion in crypto to scams – that's about one out of every four dollars reported lost, more than any other payment method.
Fake "Claim Sign" website overview
We found this scam on claim.signcommunity[.]link, yet it could also be posted on other domains. This page is disguised as the Sign Protocol website (sign.global). Sign is a decentralized protocol centered on digital data verification and token distribution. The fraudulent site implies that eligible users can receive rewards, likely in the form of SIGN tokens (Sign Protocol's native token).
It must be emphasized that this rewards program is fake, and this scam is not associated with the actual Sign Protocol or any other existing projects, platforms, and entities.
Once a wallet is connected to this deceptive page, a malicious contract is signed. The contract facilitates the crypto drainer, which enables automatic outgoing transactions from the victim's wallet.
Some drainers can approximate the value of digital assets and determine which to prioritize. This activity is automated and may appear vague – thus, it can remain unnoticed for a significant amount of time.
Furthermore, cryptocurrency transactions cannot be reversed because of their practically untraceable nature. Therefore, victims of scams like this fake "Claim Sign" webpage cannot get their assets back.

Cryptocurrency drainer scam examples
We have written about countless online scams; "Origin Ether (oETH) Airdrop", "$STARS Airdrop", and "Mind Of Pepe ($MIND) Airdrop" are merely a few of our newest articles on drainers.
Crypto scams primarily operate in one of three ways – by utilizing draining mechanisms to steal funds from exposed wallets, targeting wallet log-in credentials, or deceiving victims into manually transferring assets to scammers.
Due to how prevalent scams are on the Internet and how well-made they can be – we highly recommend vigilance when browsing and investing.
How did I open a scam website?
Drainers are often endorsed via malvertising, specifically – intrusive pop-up adverts. Some of these ads are fully functional drainers themselves; they lure users into "connecting" digital wallets by promising incredible boons. These pop-ups may even be encountered on legitimate websites that had been compromised.
Cryptocurrency-centered scams are commonly promoted through social media spam as well. We have found many instances of this on X (formerly known as Twitter). The promotional posts and direct/private messages (DMs/PMs) can be made using hacked accounts (i.e., ones originally belonging to real entrepreneurs, celebrities, influencers, projects, companies, etc.).
Other endorsement methods are not unlikely. Aside from the previously mentioned, online scams are promoted via sites employing rogue advertising networks, different types of spam (e.g., forum posts, emails, browser notifications, SMSes, robocalls/ cold calls, etc.), typosquatting (misspelled URLs), and adware.
How to avoid visiting scam websites?
Caution is crucial to online safety. Therefore, be wary of websites, advertisements, and messages that make unbelievable promises. Do not use sites offering pirated content or other questionable services (e.g., illegal streaming/downloading, Torrenting, etc.), as these webpages are typically monetized via rogue advertising networks.
Take note of URLs and enter them carefully. Do not permit dubious pages to deliver browser notifications; instead, ignore or block their notification requests. Approach incoming emails and other messages cautiously; do not open attachments or links found in suspicious mail.
Download only from official/trustworthy sources and be vigilant when installing (e.g., study terms and options, use "Custom/Advanced" settings, and opt out of additional apps, extensions, tools, etc.) – to prevent bundled/harmful software from infiltrating the system.
If your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate all threats.

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.
Example of a pop-up scam:
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.
