Despite the ability to significantly reduce the risk from account takeovers, MFA is not without its challenges. While MFA is a simple control to use, configuring it isn’t necessarily so seamless – yet it’s a control that can’t be dismissed. From MFA push notification fatigue to exploiting weaknesses in self-enrollment configurations, multiple threat actor types seem to be increasingly bypassing this important cyber defense technique.

A new report from Microsoft analyzes the evolving nature of the ransomware business into a ransomware as a service (RaaS) model and offers important lessons and recommendations for network defenders. The most notable finding, among others, is that over 80 percent of ransomware attacks can be traced to common configuration errors in software and devices. The RaaS model lowers the barrier to entry and obfuscates the identity of the attackers behind the ransomware.
The FBI has published a TLP:WHITE Private Industry Notification (PIN) warning that cyber criminals are leveraging proxies and configurations to mask and automate credential stuffing attacks on online customer accounts of U.S. businesses. These attacks, if successful, can lead to financial losses associated with fraudulent purchases, customers being notified, system downtime and remediation, and reputational cost.

Security researchers are warning defenders to be aware of ‘DarkTortilla’ which several threat actors are using to deliver a wide range of information stealers, remote-access Trojans (RATs), and other malicious payloads. DarkTortilla was first observed by researchers in October 2021, but they believe it has been active since at least 2015. Similar to other malware, threat actors are distributing DarkTortilla via spam emails with file attachments such as .ISO, .ZIP, and .IMG. In some instances, they have also used malicious documents to deliver the malware.

A new study from BlackBerry and Corvus Insurance examines the state of cyber insurance and offers recommendations for helping close the gaps in coverage affecting organizations of all sizes. The study revealed many concerning gaps in cyber insurance. Only around one fifth of all businesses surveyed have cyber insurance coverage above the median ransomware demand of $600,000. Relatedly, among small and medium businesses (SMBs) with fewer than 1,500 employees, only fourteen percent have coverage limits above $600,000.
