An Overview of the Security Breach
In a dramatic unfolding of events, the crypto market, often thrashed by exploitation and security breaches, recently shook the community with a massive fraudulent deposit incident. On September 21, the South Korean crypto exchange Upbit identified a staggering $3.4 billion in counterfeit APT tokens dubbed “ClaimAPTGift.com” deposited in the exchange’s 400,000 Aptos wallets.
Unveiling the Hacker’s Tactics
An X (formerly Twitter) account run by a group of South Korean crypto traders named ‘Definalist’ shared a post about the “huge and foolish incident.” They asserted that the scam occurred because “there was a failure to check the type arguments and all the same functions transfers were recognized as the same APT native token.” PeckShield Alert, the leading blockchain security and data analytics company, also drew attention to the attack.
The Potential Impact
Definalist mentioned that the presence of a 6 decimal in the scammer’s token averted a major disaster. They added, “If the scam token had a decimal of 8, all users would have received $25,000 instead of $250, leading to thousands of users dumping $25,000 worth of APT, causing significant disruption.” This highlights how a small oversight in token design and transfer validation can have severe consequences.
Initially, the counterfeit coins were mistakenly identified as real APT tokens by Upbit. Nonetheless, upon identifying the security breach, the platform suspended APT deposits and withdrawals, citing the necessity of system maintenance. In a statement to users, Upbit announced the suspension and stated that they would resume deposits and withdrawals once the maintenance is complete.
Resumption of Services
Following detailed scrutiny over the issue, Upbit resumed their services on September 24. The platform assured their customers of the safety of their assets despite the exploitation. Though the APT token experienced a decline in its price after the breach, it is currently trading at $5.42, exhibiting a substantial increase of 6.20%. This demonstrates the resilience of the market and investor confidence in Upbit.
The security breach at Upbit highlights the ongoing challenges faced by the crypto market in terms of security and exploitation. The incident serves as a reminder to crypto exchanges and investors to remain vigilant and implement robust security measures. The swift response by Upbit in suspending and resolving the issue demonstrates their commitment to customer protection and trust.
