Why Ransomware and BEC Attacks Are So Successful

Posted by Chris Currin on Aug 24, 2021

In 2021, ransomware remains an extremely impactful threat, with an estimated attack occurring every 11 seconds. Not only is the frequency of ransomware increasing, but it is reported the average ransom fee has increased from $5,000 in 2018 to $200,000 today, with several recent payouts crossing the $10M mark. With all of the recent spotlight on growing ransomware attack volumes and damages arising from phishing, business email compromise and account takeovers, you would certainly want to believe the cybersecurity industry would be focused on increasing security controls and detection policies to prevent such attacks.

Work-from-home requirements over the past year forced many organizations to rapidly increase adoption of video and collaboration applications like Microsoft Teams and Zoom without thorough security reviews and risk assessments.

Also, many organizations are employing these solutions in "new usage areas" such as medicine and education, that require specific access control, confidentiality, and financial management conditions.

Attackers Exploit Gap in Office 365 Best Practice Guidelines

Posted by Brian Greidanus on Apr 30, 2020

July 28, 2020 Update: Due to the complexities documented in this blog post, Microsoft is rolling out changes to e-mail forwarding configuration in Office 365. SecureSky is testing the changes that are documented at the following Microsoft URL, and will update this blog post after completion of testing to address these changes: https://docs.microsoft.com/en-us/microsoft-365/security/office-365-security/external-email-forwarding?view=o365-worldwide.

With a six times increase in COVID-19 themed incidents, security professionals need to take advantage of every possible configuration and security control to protect against this growing amount of attacks. Today we will discuss how attackers are leveraging a gap in Office 365 best practices that allows undetected eavesdropping on victim’s emails.

When attackers gain control of an account in Office 365, one of the first steps they often take is to configure email forwarding in the compromised environment. Attackers configure email forwarding in order to see new emails that arrive in the victim’s inbox – which can be responses to attacker phishing attempts sent to the victim contacts. In order to disguise their presence, the attacker does not want the victim to see those emails.
