How this kind of attack works
The website, domain or hosting was hijacked, and users signed transactions that sent funds to the attacker from a page that looked normal.
Would a pre-payment check have helped
When a frontend or domain is hijacked the payee address is freshly generated and on no list, but the hijacked host is often already in public phishing feeds, so endpoint screening catches part of this class.
