Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

You only need to make four changes...

Change:
    TextBox1.Text = TextBox1.Text & "+ " & lblCurrNum.Text & vbCrLf
to:
    TextBox1.Text = TextBox1.Text & lblCurrNum.Text & "+" & vbCrLf

Change:
    TextBox1.Text = TextBox1.Text & "- " & lblCurrNum.Text & vbCrLf
to:
    TextBox1.Text = TextBox1.Text & lblCurrNum.Text & "-" & vbCrLf


Change:
    TextBox1.Text = TextBox1.Text & "* " & lblCurrNum.Text & vbCrLf
to:
    TextBox1.Text = TextBox1.Text & lblCurrNum.Text & "*" & vbCrLf


Change:
    TextBox1.Text = TextBox1.Text & "/ " & lblCurrNum.Text & vbCrLf
to:
    TextBox1.Text = TextBox1.Text & lblCurrNum.Text & "/" & vbCrLf
