Since the beginning of this year, imToken has received numerous user reports of wallet addresses falling victim to "address phishing" attacks. In these attacks, scammers employ various tactics to deceive users into voluntarily transferring funds to them. Let's take a closer look at the tricks scammers use and work together to expose these scams!

Address Phishing Tactics

Transaction Phishing

"Address Phishing," in addition to what imToken previously disclosed as the "Same-Ending Digits Address Scam" involves sending small transactions to users' addresses using addresses with the same ending digits, creating confusion in transaction records and leading to mistaken transfers. Recently, the imToken security team has observed scammers increasing their investment in this tactic. As shown in the following image, the scammer invested 3 USDT to conduct a phishing attack and succeeded in the end.

  1. When making a transfer, please do not simply copy the address from your transaction history.
  2. After entering the recipient's address, meticulously cross-check each character to ensure the address is entirely accurate.

Clipboard Phishing

Bob encountered a strange incident where he successfully made a transfer, but his friend on the other end didn't receive the funds for a long time. After careful examination with his friend, they discovered that the recipient's address was not actually his friend's address; it was only the last few digits that matched. What puzzled Bob even more was that this address was sent by his friend through a chat application just moments ago, so there shouldn't have been any issues. Perplexed, Bob contacted the imToken team.

During communication with the imToken security team, Bob mentioned that he had downloaded Telegram from a random source he found on Baidu. As it turns out, Bob was using a counterfeit chat application, and this app had invaded his phone's clipboard, granting the scammer access to read and modify the clipboard's contents. Anything copied by the user would be obtained by the scammer, who could also alter the clipboard's content.

When the user copied a wallet address, the scammer would replace it with their own wallet address, further enhancing their phishing success rate by employing the "same-ending digits strategy."

  1. Please be sure to download from official sources and avoid installing applications of unknown origin.

  3. When making transfers, it's essential to double-check critical information such as the recipient's address and the transfer amount.

OTC Scam Phishing

Scammers often use enticing phrases like "selling at a low price" or "buying at a high price" for digital assets to lure you into engaging in private transactions.

For example, let's say Bob was approached by a scammer on Telegram who offered to purchase ETH for $2,000, claiming an urgent need. Bob thought, "The current ETH price is only $1,600; this is a great opportunity to make some money!" He then contacted the scammer, expressing his willingness to sell ETH and provided his USDT deposit address on the exchange.

The scammer initially sent a small amount of USDT to Bob's address to ensure its correctness.

After gaining Bob's trust, the scammer provided proof of the 2000 USDT transfer through screenshots and urged Bob to promptly send him the ETH. Although Bob didn't see the USDT credited to his account on the exchange for a while, the scammer provided transfer screenshots, and Bob, through Tronscan, found a 2000 U record under "his own address." Consequently, he mistakenly believed that the funds had arrived but were delayed in appearing on the exchange.

As a result, once the scammer received the ETH, they immediately cut off contact and disappeared, leaving Bob in a state of confusion.

But why did Bob see a 2000 U record under "his own address" on Tronscan yet not receive the assets?

Well, it turns out that when the scammer sent Bob the initial small amount of USDT, they conducted a total of 2 small USDT transfers.

  • One of the transfers was genuinely sent to Bob:TRNvRJT2zvdRHzgvM2Rnrtr3ANaT8b2XEQ
    • This transfer will be received by the exchange and credited.
  • The other one was sent to their own address:TY7976avKs8EbdsqFMbNButNEwDcQp2XEQ
    • This transfer was to the scammer's own address, intended to deceive Bob by having the same ending digits.

The subsequent transfer of 2000 USDT by the scammer did indeed occur, but it was merely a transfer from one of the scammer's own accounts to another and did not go to Bob's address. Due to Bob's lack of careful information verification during the transaction with the scammer, he mistakenly believed that these assets had entered his own wallet address.
