I don't understand all the details but, apparently, attackers were able to drain the 9 pools on the platform siphoning $11 Million.
If you have technical knowledge on coding, here's the article for you - ValueDeFi Incident: Incorrect Weighted Constant Product Invariant Calculation (https://peckshield.medium.com/valuedefi-incident-incorrect-weighted-constant-product-invariant-calculation-1bbaa220a02b)
Summary
This incident was due to the mis-calculation by the protocol on the adopted weighted constant product invariant for non 50–50 ratio pools. There is no flashloan or price manipulation involved. The consequence of mis-calculated invariant allows for draining of affected pool funds. Currently, the bug has been exploited to attack 9 non 50–50 ratio pools with the estimated loss of $11M.
Coinmarketcap also covered the story HERE (https://coinmarketcap.com/ro/headlines/news/bsc-based-valuedefi-exploited-for-11m-by-scammers/) and enumerated the affected pools:
- 15k BNB – 2.7k
- FARM – 1.7k
- BASv2 – 8.5M
- BDO – 68.3k
- BUSD – 41.4k
- MDG – 945k
- VBOND – 1.2M
- BAC – 11k FIRO
