Cofense posted a blog detailing a phishing campaign utilizing unique tactics that is targeting multiple sectors, including energy, financial services, commercial real estate, food, and manufacturing. This campaign, which spoofs eFax and Microsoft 365, approaches targets in a nontraditional way by pretending to be from a survey site asking for customer feedback.
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.

What Happened?
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.

USBs, those innocuous looking little portable storage devices, while useful in utility are still dangerous for utilities. These devices that are practical for transferring legitimate files and documents are equally functional for transferring malware into and out of production OT/ICS networks – including air-gapped environments. In the Honeywell Industrial Cybersecurity: USB Threat Report 2022, Honeywell’s Cybersecurity Global Analysis, Research, and Defense (GARD) team once again looked at the increasing threat caused by these modest devices.
