New Scam Alert: Beware of Phishing URLs Disguised as Transfer Addresses
Recently, a new phishing scam has caught our attention. This scam typically occurs in chat applications like Telegram, beginning with off-exchange transactions. Before the actual transaction, the scammer asks the victim to transfer a small amount, say 0.1 USDT, to verify if their address poses any risks. The scammer then sends a so-called “public chain” address for the transfer, emphasizing that it must be entered in the wallet browser for the transaction to proceed. Unfortunately, once the victim enters this “public chain” address in their browser, they discover that all tokens in their account have been stolen.
So what exactly happened?
Analysis of the Scam
Upon analyzing the information provided by the victims, we discovered that this is not a case of simple transfer theft. Note: Addresses have been obscured to protect the victims’ information.
Based on our experience, this appears to be a phishing theft caused by authorization. The contract caller (TK…Gh) transferred 271,739 USDT from the victim’s address (TX…1W) to the scammer’s address (TR…8v) by invoking the transferFrom function.
At this point, we focused on the “public chain” address mentioned by the scammer: 0x2e16edc742de42c2d3425ef249045c5c.in
At first glance, the address seems unproblematic. But a closer look reveals significant issues! First, the transfer occurred on TRON, but this is an address starting with 0x; secondly, upon further inspection, it turns out that this is not an address but a website ending with .in.
Upon analyzing this website, we found that it was created a month ago (October 11th) with the associated IP being 18.104.22.168:
Similar websites exist under this IP, all created within the last month:
Currently, only 0x2e16edc742de42c2d3425ef249045c5b.in is accessible. When searched in a wallet browser, this page only allows the selection of the TRON network.
After entering an amount and clicking next, it shows as a contract interaction.
We decoded the data in the Data section and found that the scammer (TYiMfUXA9JcJEaiZmn7ns2giJKmToCEK2N) lures users into signing an increaseApproval. Once the user clicks Confirm, their tokens can be stolen by the scammer using the transferFrom method.
An analysis of this scammer’s address reveals that users have already been tricked.
Most of the victim’s USDT was transferred to the address TLdHGHB8HDtPeUXPxiwU6bed6wQEH25ZKQ.
Using MistTrack to check this address, we found it received over 3,827 USDT.
Further analysis of other addresses is not discussed in detail.
