BEC Attacks: The #1 Email Threat

BEC attacks have cost more than $43 billion in losses since 2016, and they have become one of the most successful and financially damaging online crimes.
Once the cybercriminal has gained access to an email inbox, usually with a phishing scam, they will search the inbox for high value email threads such as email conversations with suppliers or other individuals in the company to gather information. Leveraging this information, they’ll send an email message that appears to come from a trusted source.
The problem is that BEC attacks bypass legacy email solutions. As the email comes from a trusted source, it is able to pass rule-based security controls, such as DMARC, DKIM and domain authentication, without detection.
