MITM malware can hijack most 2FA methods. There are well over 20 2FA common methods and the vast majority are susceptible to a MITM attack. But the most common attack is replay attacks and all 2FA methods thwart that. Some 2FA methods are trivial to hijack like SMS and others require more effort. Some are pointless to hijack if they are from a separate channel, session based and paired to a trusted pinned device like remote login 2FA.
