When Faatin Amal kills former Mossad officer Namir Eschel her pistol and silencer are silver/nickle plated. When she removes the pillow from his face after suffocating him they are black.
At around 24 minutes in, when Namir Eschel's information Is displayed, everything written in Hebrew characters is absolute gibberish, as if someone was hitting random keys on the keyboard. Also, as far as Israeli names are concerned, the name "Eschell" would much more likely be pronounced "eh-shell" than "eh-khell".

When Gibbs and Tony are in Abby's lab looking at the big screen and they both take a drink of their coffee at the same time, when they pull the cup down you see the drink hole of Tony's cup is to the left, if he would have actually taken a drink coffee would have spilled all over him.
