The Wall Street Journal (WSJ) and CNBC reported on the 3rd (local time) that the virtual currency Solar System was hacked and leaked from nearly 8,000 wallets.

According to the Solana Foundation, a hacker exploited a loophole in the system at 1 a.m. (2 p.m. Korean time) in the U.S. Eastern time to steal cryptocurrency from Solana’s cryptocurrency wallet.

The Twitter account “Solana Status,” which informs the news of the Solar Network, said the number of wallets affected by the attack was 7,767, but blockchain analysis company Eliptic estimated it to be 7,936, which is more than this.


The leaked cryptocurrency was Solar and Stable Coin (USDC). WSJ quoted blockchain security company PeckShield and reported that the damage was $8 million (about 10.4 billion won), and CNBC reported that according to Eliptic, it is estimated to be $5.2 million (about 6.8 billion won).


The wallet where the virtual currency was leaked was a wallet provided by Phantom, Slope, and Trust, and was a “hot wallet” connected to the Internet.

The details of the hacking were not known.

However, a spokesperson for Solana said, “It doesn’t seem to be a bug in Solar’s core code, and it seems to be a bug in software used by some wallets famous among Slana users.”

However, Phantom said in a tweet posted on Twitter, “I don’t think it’s just Phantom’s problem.”

In an interview with CNBC, an Eliptic official said, “It seems to be due to loopholes in certain wallet software rather than Solar or blockchain itself,” while giving clues that the root cause of the leak is still unclear.

Ottersec, a blockchain audit company, pointed out that when the virtual currency was withdrawn, there was an actual owner’s signature, and said that a kind of personal key seemed to have been violated. A private key refers to a security code that allows access to virtual currency.
