CoinVoice has recently learned that according to DL News, according to a report by Aaron Li, a participant in the public chain project Harmony's ecosystem, in December last year, due to a loophole in Harmony's staking contract, some staking users received an additional 150 million ONE tokens, worth approximately US$2.2 million.
Aaron Li accused the Harmony team of not responding to the vulnerability within 5 days of the report being released, which led to the problem continuing to expand. Eventually Aaron Li decided to investigate the issue himself and found a temporary solution on December 12.
On the other hand, Harmony software engineer Casey Gardiner accused Aaron Li of "failure to report the vulnerability in a timely manner" and selling ONE tokens during the vulnerability. [Original link]
