I found this comment by a Rabbi on Judas Iscariot::
Judas is often given the nickname "Iscariot." In some places where English New Testaments have "Iscariot," the Greek text actually has "apo Kariotou" which means "from Karyot." Karyot was the name of a town in Israel, probably the modern site known in Arabic as Karyatein. We thus see that the name Iscariot is derived from the Hebrew "ish Karyot" meaning "man from Karyot." This is in fact the accepted modern Christian understanding of the name. However, in the past, the Christians misunderstood this name and legends arose that Judas was from the town of Sychar, that he was a member of the extremist party known as the Sicarii and that he was from the tribe of Issacher. The most interesting misunderstanding of the name is its early confusion with the word scortea meaning a leather money bag. This led to the New Testament myth that Judas carried such a bag, which in turn led to the belief that he was the treasurer of the apostles.
