Revealing mistake: When Jensen is investigating the missing 4 million dollars from the account, we see the screen on his laptop. Among other things, it shows a picture of Fadhil's passport, which looks like it has a watermark on it, readable as http://slawek.com. Indeed, going to http://www.worldpassports.org/americas/pages/bolivia.htm you will find the passport pictured there. (01:01:35)
Other mistake: In the scene where Jensen is attempting to decrypt the password on the hard drive with the algorithm, he uses the command "traceroute d-hea" which is commonly used to test network connectivity, not decrypt passwords.Then follows it with the command "dir" to reveal HTML code instead of directory structures.
