Examples of common scams

Phishing scams are fraudulent attempts to steal sensitive information, such as login credentials, passwords, and private keys, by disguising as a trustworthy entity, such as a legitimate cryptocurrency exchange or wallet. They often use fake emails, websites, or pop-ups to trick users into entering their information.

An example of a phishing scam in the cryptocurrency industry is a fake email or pop-up that appears to be from a well-known exchange, such as Binance, and asks the user to enter their login credentials or private key. The information is then used to steal the user's funds.

What You Need to Know

Pig Butchering scams are a form of long-term fraud, aptly named because the scammer "fattens up" their victim over time before draining them of all their funds.

Initial Contact

The scam often starts with an unsolicited message via SMS, social media, or dating apps. The initial message might appear harmless, like a wrong number or a casual greeting. Once the target responds, the scammer seizes this as an opportunity to initiate a conversation and build rapport.

The Investment Trap

After gaining your trust, the scammer introduces the idea of investing in cryptocurrency. They may even let you withdraw a small amount initially to prove the "validity" of the investment. However, when you try to withdraw more, they'll claim that fees or other expenses need to be paid.

Red Flags to Watch For

• Quick attempts to move the conversation to private messaging apps
• High-pressure sales tactics or deadlines
• Promises of unusually high returns

Protect Yourself
 

• Be cautious of individuals who claim to have exclusive investment opportunities.
• Never share sensitive information like your banking details or social security number.
• If an offer sounds too good to be true, it probably is.

Final Stage

Once the scammer believes they've maximized your investment, they will disappear, shutting down accounts and making off with your money.For more information, please also refer to the FinCEN Alert on Pig Butchering Scams.

SIM swapping, also known as SIM hijacking, is a type of attack where a malicious actor gains access to a victim's mobile phone number by tricking the mobile carrier into transferring the number to a new SIM card controlled by the attacker.

Here is how the attack typically works:

• Gaining access to personal information: The attacker first gathers personal information about the victim, such as their full name, date of birth, and address. This information can be obtained through social engineering, phishing scams, or by purchasing it on the dark web.
• Contacting the mobile carrier: The attacker then contacts the victim's mobile carrier, posing as the victim and claiming that they have lost their SIM card or that it is damaged. The attacker provides the carrier with the personal information they have obtained to prove their identity.
• Transferring the number: If the attacker is successful in convincing the carrier, the carrier will transfer the victim's phone number to a new SIM card controlled by the attacker. The attacker can then use the new SIM card to receive calls and text messages meant for the victim, including authentication codes and two-factor authentication (2FA) alerts.
• Taking control of accounts: With access to the victim's phone number, the attacker can reset passwords and take control of the victim's online accounts that are protected by 2FA, such as email, social media, and cryptocurrency accounts.
• Stealing assets: If the attacker gains access to the victim's cryptocurrency accounts, they can steal their assets by transferring the funds to their own accounts.

It is important to note that SIM swapping attacks are becoming increasingly common and can cause significant financial losses for victims. To protect against these attacks, it is recommended to use strong passwords, enable 2FA on all accounts, and be cautious of suspicious emails and phone calls asking for personal information. 

Additionally, some mobile carriers offer added security measures, such as multi-factor authentication or a temporary freeze on the mobile number, that can be used to prevent SIM swapping attacks.

These scams promise high returns on investments, but in reality, they are just paying early investors with the money deposited by new investors. The scheme eventually collapses when there are not enough new investors to pay the existing ones.

An example of a fake exchange is a website that appears to be the legitimate cryptocurrency trading venue, Uphold, but with a slight difference in the URL or logo. Users who deposit funds into this fake exchange will lose their money, as the exchange is not connected to the real Uphold platform.

Cloud mining scams are fake companies that claim to be mining cryptocurrencies for their investors. They take money from their investors and run, leaving them with no returns and no way to recover their funds.

Wallet scams are fake wallet services that steal users' private keys and funds. They often mimic legitimate wallet providers and trick users into downloading their software or providing their private keys.

Fake giveaways are scams that promise to give away free cryptocurrencies, but actually steal funds from the participants. They often require users to send a small amount of cryptocurrency to a specific address to enter the giveaway, but once the funds are sent, they are stolen and cannot be recovered.
