2.2 Hidden Information

Suppose part of EGOP's message contains the passage of text "TUBSU SIF BUUBDL". Assuming EGOP uses English, this portion doesn't appear to contain meaningful text. However, you might notice a pattern to the letters -- try to substitute a letter ``one-lower'' in the alphabet for each given letter. So, the letter 'B' becomes 'A', the letter 'C' becomes 'B', and so on. Eventually, you will discover that EGOP ``hid'' the message "START THE ATTACK".
