(CNN) Israel says it is ‘at war’ after Hamas surprise attack.

Israel’s hacking expertise is second only to NSA. Israel intensively monitors Gaza electromagnetic emissions. So how did Hamas evade detection? The definitive answer cannot be reached unless technological surprise can be excluded.  With exclusion, there are only a few possible categories:

• A new dark web infrastructure running on virgin hardware, concealed by something analogous to CDMA or spread spectrum.
• Steganography.
• The low-tech Kremlin solution: typewriters/carbons, paper and pencil.

If technological surprise reveals, it will come as a thunderclap.

How did Hamas gain confidence their plans were undetected? Do they have a mole?
