Scam Protection
IsThisSpam protects you from the most common online threats. Learn what to watch out for.
Deceptive emails or texts pretending to be from trusted institutions like banks or government agencies. They trick you into sharing passwords, credentials, or multi-factor authentication (MFA) codes. Look for urgent language like "account suspended," generic greetings, and mismatched domain names in the sender's address or links.
Fake e-commerce storefronts offering highly discounted popular items, electronics, or designer brands that never arrive. These sites often use brand names with slight variations or extra words (e.g., "discount-brand.com") and have no verified physical contact information. Check for missing HTTPS certificates, domain age less than 3 months, and payment terms that demand crypto, gift cards, or bank transfers.
High-yield investment schemes, cryptocurrency giveaways, and "get-rich-quick" opportunities promoted on social media or direct messages. They promise high guaranteed returns with little to no risk, which is a key mathematical red flag. Scammers often pressure you to act immediately, request payment via untraceable digital assets, and show fabricated earnings dashboards.
Scammers create fake online profiles on dating apps or social media, building deep emotional trust over weeks or months. Once trust is established, they fabricate urgent emergencies (e.g., medical crises, frozen bank accounts, or travel costs) to request wire transfers or gift cards. Key detection signals include requests to move communication off the original platform, refusal to video call, and stories that constantly change.
Deceptive pop-ups, search ads, or emails claiming your computer is infected with viruses, warning that your personal data is at risk. They instruct you to call a toll-free number where a "technician" asks to download remote-access software (like AnyDesk or TeamViewer) to fix the issue. Legitimate tech support departments will never contact you proactively via pop-ups to ask for remote access.
Fake package tracking notifications sent via SMS or email, mimicking postal services like USPS, DHL, or FedEx. They claim a parcel is held due to an incorrect address or unpaid customs fees, requesting a small fee and personal details to schedule redelivery. Spot these by checking the URL—official postal services do not use random domains (e.g., "usps-redelivery-fees.top").
