On Thursday, September 29th, 2022, GTSC–a Vietnam-based cybersecurity company–published a blog detailing intrusion they investigated that chained together two exploits for Microsoft Exchange zero-day vulnerabilities to achieve remote code execution (RCE). Technical details around how to exploit these vulnerabilities were not provided.

Welcome to October, the spookiest month of the year! No, we’re not talking cute kids dressed as their favorite cartoon character on a mission to collect a mountain of candy. That’s a treat. We’re here to talk about the tricks, and how you can keep from falling for them. That’s right, it’s Cybersecurity Awareness Month!

Arctic Wolf Labs regularly collects and analyzes data and insights from the incident response activities of Arctic Wolf’s incident response business unit, Tetra Defense. These insights, as laid out in the charts and graphs in this blog, enhance the threat detection capabilities of the Arctic Wolf Security Operations Cloud, and are leveraged by Arctic Wolf’s community of partners.

Ah, the CISO. In the past decade no job title has become more fashionable. At the same time, no job title has carried more of an air of mystery. What, exactly, is a CISO? What do they do? How do they do it? And how can you become one? Let’s find out.

On Friday, September 23, 2022, Sophos disclosed a critical code injection vulnerability impacting Sophos Firewall. This vulnerability, assigned CVE-2022-3236, affects Sophos Firewall versions v19.0 MR1 (19.0.1) and older and could lead to remote code execution. In order for a threat actor to exploit this vulnerability, WAN access would need to be enabled for the Webadmin and User Portal consoles.

Understanding the ins and outs of threat intelligence can be complicated for an organization. If your business is anything but cyber, it’s understandable to be overwhelmed by terms like ransomware, cryptocurrency, and DDoS attacks, especially in relation to your systems and assets. That’s okay.

Signed into law in March of 2022, the Strengthening American Cybersecurity Act (SACA) gives federal authorities an overview of all cyber attacks against critical infrastructure in the United States for the very first time. SACA has three parts: SACA comes at a time when governments are facing a significant paradigm shift.

It was the worst-case scenario for Uber, the popular ride-sharing app, when the company suffered a major data breach in early September. While the extent of the damage, and the data potentially stolen, is still being uncovered, the attack — and the methods used to execute it — can be examined and used to teach other organizations what (and what not) to do.

Imagine a burglar. They’ve spent large amounts of time researching their target — your house. They’ve perfected their infiltration techniques, found your weak points, learned your schedule, and know the best time to strike. They’ve shown up when you least expect it and jimmied open the lock on the back door. And now, rather than head inside and steal your valuables, they hold the door open for someone else.

The Arctic Wolf Labs team recently investigated a Lorenz ransomware intrusion, which leveraged a Mitel MiVoice VoIP appliance vulnerability (CVE-2022-29499) for initial access and Microsoft’s BitLocker Drive Encryption for data encryption. Lorenz is a ransomware group that has been active since at least February 2021 and like many ransomware groups, performs double-extortion by exfiltrating data before encrypting systems.
