Security and trust are crucial in the dynamic world of cryptocurrency. Upbit, a cryptocurrency exchange in South Korea, recently had an incident that highlighted the difficulties presented by fake tokens and the value of thorough verification processes. The intriguing story of a bogus APT token fraud that briefly interfered with Upbit’s services is explored in this article, along with its ramifications for cryptocurrency exchanges and investors.
On September 24th, the cryptocurrency community was shaken when Upbit, one of South Korea’s leading cryptocurrency exchanges, abruptly halted all Aptos (APT) token-related services. The reason behind this sudden decision was an “abnormal deposit attempt” that raised concerns about the security and integrity of the exchange’s wallet system.
The Unveiling of a Scam
The source of the problem was quickly identified—a recently created fake APT token known as “ClaimAPTGift.com.” This imposter token had ingeniously infiltrated approximately 400,000 Aptos wallets. Its creation date, September 21, marked the inception of a scam that would momentarily bewilder the crypto space.
The modus operandi of the scam was familiar—an airdrop. Users found themselves receiving tokens without any action on their part. However, the catch was that these tokens concealed malicious links, directing unsuspecting recipients to phishing websites. The scheme was a classic example of crypto fraud.
What set this scam apart, and eventually led to an unforeseen twist, was Upbit’s response. The exchange seemingly overlooked the red flags in the source code of the fraudulent tokens, thus failing to differentiate between the fake APT tokens and the legitimate Aptos tokens.

– It seems that during the process of reflecting $APT coin deposits, there was a failure to check the type arguments, and all same functions transfers were recognized as the same APT native token.

The repercussions of this oversight were far-reaching. Users who had unwittingly received the fake APT tokens were suddenly able to trade them on Upbit’s platform as if they were genuine Aptos tokens. It was akin to a mirage of authenticity, and some individuals took advantage of the situation, capitalizing on the confusion.
Reports emerged of users selling the fake APT tokens and profiting from their ill-gotten gains. The situation became increasingly complex, with Upbit’s customer center scrambling to address the issue. In an effort to rectify the situation, the exchange initiated a process of requesting refunds from users who had participated in trading these counterfeit tokens.

A Swift Resolution and Ongoing Vigilance
Fortunately, Upbit acted swiftly to resolve the predicament. By September 24th, at 11:00 PM local time, the exchange confirmed that it had completed the wallet inspection and resumed Aptos deposits and withdrawals. It provided assurance that the “action against the abnormal deposit attempt” had been successfully carried out, and there were no further concerns regarding Aptos transactions.
However, Upbit issued a cautionary note to its users. Delays in processing deposits and withdrawals were possible, and temporary price fluctuations in the APT tokens might occur in comparison to other exchanges. This incident serves as a stark reminder of the vigilance required in the cryptocurrency realm.
Despite the temporary disruption, Aptos (APT) maintained its market presence. Trading at $5.31 over the past 24 hours, it demonstrated resilience. Notably, the price of APT on Upbit slightly deviated, standing at around $5.56 according to Coinmarketcap.
The Upbit APT token saga illuminates the challenges exchanges face in verifying the authenticity of tokens and the importance of robust security measures. It also underscores the need for users to exercise caution and due diligence in the ever-evolving cryptocurrency landscape.
