The finance department staff are requested to transfer funds to a bank account.

The misspelt domain name.

From: "CEO Name" <>

Below are two regular expressions for a domain called These expressions are useful not just for these scams, but phishing in general. For efficiency, the regexes assume the first character is never changed, which is a fairly safe assumption because otherwise the domain would not look similar enough. Simply copy the pattern and apply to your own domain(s).

Character Substitution Regex
