Approx. 17 wallets were compromised with at least $7.2M stolen. Approx. $1.4M may be compromised in another 4 addressed. These two scenarios as leading/most probable:

1. Each individual has had their seed phrase compromised through social engineering/phishing.
2. A MyAlgo.com compromise leading to targeted exfiltration of unencrypted private keys.

Updated 3/21: Preliminary analysis indicated that the attacker employed a MITM attack to inject malicious code between the actual MyAlgo wallet and the user. The malicious proxy fetched the original MyAlgo code, modifying it with harmful code before presenting a malicious version to the user.
The injected code was designed to record users' passwords and encrypted seed phrases and transmit them to a server controlled by the attacker.
