Attackers are employing a variety of methods, including phishing emails with malicious attachments, obfuscated script files, and Guloader PowerShell, to infiltrate and compromise victim systems. Invoice fraud, a form of business email compromise (BEC), is one of the popular methods used by attackers to deceive victims. In this type of scam, a third party requests payment fraudulently, often by impersonating a legitimate vendor
Invoice scams pose a significant threat to businesses, as they can result in substantial financial losses and irreparable damage. According to the FBI IC3 report, in 2022, BEC attacks caused $2.7 billion in losses to US victims, making it the most pervasive form of business email compromise.
Some indicators of fraudulent email invoices include requests for personally identifiable information (PII), unusual requests such as changes to banking or payment information, and invoices with unusual dollar amounts. Additionally, attackers often use obfuscation techniques to evade defenses and make their malicious activities more difficult to detect.
