Security researchers have analyzed 600 attacks on real estate in six months. Main threat is the business email compromise (BEC) fraud, which aims to divert funds from a transaction to a bank account controlled by the bad guys. Phishing for login credentials remains a popular trick, with attackers spoofing Office 365 and DocuSign pages to collect the sensitive info. The big money from real estate transactions has attracted a larger number of fraudsters, threatening this business with a wider set of tactics and tools. Some of them cast a wider net to catch as many victims involved in a transaction as possible.
