Apollo is a command-line tool designed specifically for sending spearphishing emails.
A problem I was facing was that using normal email clients, making repeatable emails, juggling multiple accounts and identities was a chore.
That is why we created Apollo.
./Apollo.rb --template Uri --email [email protected] -s "Read this email please." -i john --vars "ip=192.168.1.221,share=share,filename=certificate.docx"
Templates are stored in the templates/ directory, and are in the ERB format. They contain variables that can be replaced on email send.
In the above example, we use the Uri template, we send to harry.hack,
