Upbit Resumes Aptos Services After APT Token Scam Saga

This development comes in the wake of a meticulous resolution of an issue that had initially led to an erroneous recognition of a scam APT token as legitimate.

On September 24th, Upbit took the unexpected decision to halt Aptos token services, citing an “abnormal deposit attempt” as the reason behind this sudden suspension. This move triggered a thorough inspection of the exchange’s wallet system, aiming to unearth the root cause of the problem.

The masquerading token was part of a classic token airdrop scam strategy, wherein unsuspecting users receive tokens that contain embedded links redirecting them to phishing websites.

In response, Upbit’s customer center has initiated efforts to reclaim funds from users who unwittingly engaged in transactions involving counterfeit APT tokens. The exchange has taken swift corrective measures, and as of September 24th at 11:00 pm local time, Upbit announced the resumption of deposits and withdrawals after completing a thorough wallet inspection.

The exchange’s swift response to this incident demonstrates its commitment to maintaining the security and integrity of its services, reassuring its user base in the process.
