Zero transfer scam involves sending small amounts of USDT to your wallet, often so insignificant that they go unnoticed. These attacks utilize intricate methods and crypto address manipulation, making them a challenge to detect even for seasoned crypto users. Therefore, understanding how USDT scams operate and implementing effective protective measures is crucial. To illustrate the complexities and potential dangers, we will investigate a specific case study of this scam, also called the crypto dust attack.
What is a Zero Transfer Scam?
Zero transfer scams involve employing bots, scripts, and automation to exploit human vulnerabilities, leading to confusion, manipulation, and ultimately, financial loss. Our research team delves into a case study of a crypto zero transfer scam that occurred on the Tron Network in September 2023. The scam originated with a seemingly legitimate transfer on the blockchain, triggering a chain of events that resulted in the theft of 34,300 USDT.
Step 1: Tracking a Seemingly Innocent Transaction
In this particular case study, the victim is TYsHgAbRjHj6a4ReBceGJrU7XzsedG1rQw (referred to as 'Qw' for simplicity, based on the last characters of its wallet address). The scam started on 2023-09-20 at 14:55:03 (UTC).
“Qw“executed an honest transaction of 57,000 USDT on the TRC20 network to TKEoc3rhSZvzeE3RmRfAWWkXCuFScSvuNv (referred to as "Real Nv", based on the last two characters of its address).
This transaction appeared innocent, similar to the countless USDT transfers that occur daily on the Tron blockchain. However, this seemingly ordinary transaction laid the foundation for an elaborate and meticulously planned crypto dusting attack. The scammers developed a script that systematically scans the entire Tron blockchain for transactions. After identifying the legitimate transaction between the two parties, the script triggers the next phase of the attack.
Step 2: Creating a Fake Address
Based on the assumption that the owner of the "Qw" address might repeat the USDT transfer to the "real Nv" address, scammers devise a plan to exploit. They craft a newly generated address that closely resembles the legitimate "real Nv" address. This deceptive address, the "fake Nv" address, is designed to trick unsuspecting users into sending funds to the wrong destination. The scammers' plan lies in their ability to create addresses that mimic the real ones with remarkable precision, often differing only by subtle, easily overlooked variations.
The success of this deception lies in the scammer's ability to create an address, TKEo3uWqbw2Jhs8pSEqDBgTgUj6iKSvuNv, that closely resembles the authentic "real Nv" address. The subtle differences between the two addresses make this stage particularly dangerous. By creating confusion, the scammers aim to manipulate the victim, "Qw" in this instance, into accidentally selecting the fake address instead of the legitimate one during USDT transactions. This misdirection allows the zero transfer scam to proceed, leading the unsuspecting victim to send cryptocurrency to the scammers' created address, known as "fake Nv." Comprehending this process is essential for recognizing the tactics employed in these zero transfer attacks on Tron Network, also called USDT scams.
Step 3: Setting the Crypto Dust for the Zero Transfer Attack
In a calculated move, the scammers execute a strategic maneuver. They initiate a small transaction of USDT, amounting to 0.634101 USDT, from the newly created "fake Nv" address to the victim's "Qw" address. The insignificant sum involved is often deliberately chosen to go unnoticed by the unsuspecting victim. This seemingly harmless transaction subtly manipulates the order of transactions displayed in the victim's wallet, strategically positioning the malicious "fake Nv" address at the top of the transaction history.
By strategically placing the "fake Nv" address at the top of the transaction history, the scammers increase the probability that the victim, "Qw," will accidentally copy and paste the incorrect "fake Nv" address, leading to a crucial error in their subsequent transfer. This deliberate manipulation sets the stage for the victim to fall prey to the scammers' carefully orchestrated deception.
Step 4: Sending Funds to the Fake Address
In a crucial moment of misjudgment, the unsuspecting victim, "Qw," falls prey to the scammers' deceptive scheme. Overlooking the crucial middle characters of the receiving address, "Qw" mistakenly identifies the address ending with "Nv" as the genuine "Nv" address. This fatal error leads to the accidental copying of the fake "Nv" address, which is subsequently used for the intended transfer. Tragically, in this instance, "Qw" sent 34,300 USDT to the fake "Nv" address!
The scammers' evil plan is completed with the "Qw's" unintentional transfer of funds to the fake "Nv" address, marking the successful execution of this zero transfer scam. The consequences of this seemingly minor oversight are profound. The USDT intended for the legitimate recipient is sent to the scammers, resulting in a devastating loss of 34,300 USDT. This fact marks the peak of the USDT scam, leaving the victim robbed of their cryptocurrency.
Step 5: An Automation Sends Stolen Funds to the Master Wallet
Upon the successful transfer of USDT from the victim's wallet to the scammers' fake address, the final stage of the address poisoning attack unfolds. The scammers swiftly employ a bot to move the stolen USDT directly to its ultimate destination, the "Master Scammers Wallet" (TT5ikPDq4T2ZB1CH7S3DcFmPR6ej3zZRzg).
A final transfer from the "fake Nv" address sends the 140,00.21 USDT to the "Master Wallet".
This rapid scheme serves as an attempt to launder the illicitly obtained USDT, obscuring its origins and rendering it virtually untraceable and unrecoverable. By transferring the stolen funds to their genuine wallet or an external account, the scammers seek to sever any connection between the misappropriated cryptocurrency and the victim's wallet. In essence, they strive to erase any evidence of their involvement, making it exceedingly difficult for the victim to track the trail of the stolen funds.
In conclusion, 629,888 USDT was stolen in a few days!
Comprehending this final stage is crucial for fully grasping the malicious intent behind crypto dust attacks and the daunting challenges victims face in seeking retribution. Once the USDT is transferred beyond the victim's grasp, the chances of recovering the stolen funds dwindle to zero. Sadly, "Qw" is not the sole victim of this unscrupulous group of scammers. As evident in the transaction history of the "Master Wallet" (zg), five distinct USDT holders have fallen prey to this deceptive scheme, each incurring varying losses, but all misled by the same cunning tactics.
Our PlasBit research team has uncovered the far-reaching implications of this address poisoning attack, which has left crypto users reeling from the devastating consequences. These ruthless scammers have amassed a staggering 629,888 USDT in a matter of days.
Protecting Yourself From The Zero Transfer Scam
In the wake of the detailed exploration of the zero transfer scam, which resulted in the loss of 34,300 USDT, it becomes imperative to delve into comprehensive guidelines to empower cryptocurrency users to shield themselves from falling prey to such deceptive schemes. The sophistication of these attacks necessitates a heightened level of awareness and prudence from users. Below are in-depth strategies to fortify your defenses against the Zero Transfer Scam:
