Crypto exchange Upbit was targeted by hackers 159K times in H1: Report

cointelegraph.com:

South Korean cryptocurrency exchange Upbit has been targeted by hackers on more than 159,000 occasions in the first half of 2023, according to its operating firm.

The figures were reported by Dunamu — the firm operating Upbit — to South Korean Representative Park Seong-jung of the People Power Party, according to an Oct. 9 report by South Korea-based Yonhap News Agency.

The figure marks a 117% increase from the first half of 2022 and a whopping 1800% increase from the first half of 2020.

Upbit is one of South Korea’s largest cryptocurrency exchanges with 24 hour trading volume of around $1.2 billion, according to CoinGecko. Other major exchanges include Bithumb, Coinone and Gopax.

To counter the rise in security breach attempts, Dunamu said Upbit increased the proportion of funds it holds in cold wallets to 70% to strengthen security. Upbit also upped its security measures for funds held in hot wallets.

Hot wallets tend to be hacked more often than cold wallets because the private keys are stored online as opposed to a cold wallet where they’re stored on external hard drives and USBs.

Upbit suffered a $ 50 million exploit in 2019. But since then, Upbit hasn’t suffered a single security breach, a Dunamu spokesperson told Yonhap.

However, Upbit had to halt Aptos token services in late September after the platform failed to recognize a fake token “ClaimAPTGift.com” which made its way to 400,000 Aptos wallets.
