Weekly Blockchain Security Watch
July 10 to July 16
From July 10, 2023 to July 16, 2023, all security incidents that had occurred can be categorized into Security Hacks and Rug-pulls.
1. Social Media Accounts Compromised
From July 10 to July 16, the following social media accounts were compromised and phishing links might be sent in these accounts:
holoride@holoride, Overnight.fi@overnight_fi, ReleapProtocol@Releap_IO, UFOGaming@TheUFOtoken, StarProtocol@star_protocol, Superlotl@superlotls, SwapDexBlockchain@SwapdexO, Tapio Finance@TapioFinance and HouseHaeds@HouseHaeds
2. Arcadia Finance Suffers Exploit
On July 10, a multi-chain deployed DeFi application Arcadia Finance suffered an exploit.
The root cause is that the application calculated its token price based on the assets stored in the storage and this allowed the hacker to call vaultManagementAction to launch the attack.
The hacker’s address is 0xd3641c912a6a4c30338787e3c464420b561a9467 on OP.
Crypto assets worth around US $ 455K on both Ethereum and Optimism were exploited in this incident.
3. Libertify Suffers Exploit
On July 11, a multi-chain deployed DeFi application Libertify suffered an exploit.
The root cause of the exploit is the applicaiton didn’t have re-entrancy protection for its deposit function of the LibertiVault contract. This allowed the attacker to reenter the vulnerable function to steal assets.
The hacker's addresses are 0xfd2D3ffB05aD00E61e3c8D8701cb9036b7A16D02 on ETH and 0xfd2d3ffb05ad00e61e3c8d8701cb9036b7a16d02 on Polygon.
Crypto assets worth around US $ 452,000 were exploited in this incident.
4. Rodeo Finance Suffers Exploit
On July 11, an Arbitrum deployed DeFi application Rodeo Finance suffered an exploit.
The root cause is that the application had a vulnerability in its oracle. The hacker exploited this vulnerability to manipulate a token price.

A Reminder for Project Teams: Always test thoroughly. Do smart contract audits before deploying smart contracts on-chain. Be alert to any anomalies happening in the various social media accounts you manage.
A Reminder for Crypto Users: Be cautious about suspicious links, emails, websites, and projects launched by teams without established reputations.
It is important for everyone in the crypto community to gain understanding and practice sufficient levels of cybersecurity.
