Claim Manta scam

"Claim Manta" scam in detail

This scam is promoted via posts on X (formerly Twitter) written using stolen or fake accounts. Clicking the link provided in those posts leads to a deceptive website hosting a fake MANTA giveaway. On this site, a scheme is outlined, stating that individuals acting as referrals stand to earn a 30% commission in BB or ETH, as well as MANTA, from both claiming and purchasing during the presale.

Additionally, those who refer friends will receive a 10% commission from the swap fee if their referral friend engages in a Swap Airdrop. The site also provides an option to claim MANTA. This scam aims to deceive individuals by leading them to believe they need to connect their wallets, ultimately tricking them into approving a malicious contract.

Upon approving a malicious contract, a drainer is activated, which transfers crypto funds from the victim's wallet to the one controlled by scammers. Thus, individuals who fall for this scam lose all their cryptocurrency stored in the compromised wallet. Unfortunately, recovering stolen cryptocurrency is nearly impossible due to the irreversible nature of transactions.

How did I open a scam website?

Users might inadvertently encounter fraudulent websites via phishing emails containing malicious links that, when clicked, redirect users to fake websites. Additionally, misleading advertisements on shady sites or social media and notifications from untrustworthy pages can lead to these deceitful online destinations.

Additionally, users can land on scams via pages that utilize rogue advertising networks, commonly used by illegal movie streaming pages, torrent sites, and similar websites.

How to avoid visiting scam pages?

Always scrutinize URLs, ensuring they match the legitimate website's address. Avoid clicking on unsolicited links within emails or messages, and be cautious with pop-up ads on dubious websites.
