I haven’t seen many posts about this on CT yet but it’s suspected over $9.2m (19.5M ALGO, 3.5m USDC, etc) has been stolen on Algorand as a result of this attack from Feb 19th to 21st.
ChangeNow shared they were able to freeze $1.5m.
IMPORTANT: ⚠️We strongly advise all users to withdraw any funds from Mnemonic wallets that were stored in MyAlgo. As we still don't know the root cause of recent hacks, we encourage everyone to take precautionary measures to protect their assets. Thank you for your understanding.
