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.

In our companion blog post, Vedere Labs analyzed the main ransomware trends we observed in the first half of 2022, including state-sponsored ransomware, new mainstream targets and evolving extortion techniques. Ransomware is the main threat targeting most organizations nowadays. However, three other notable cyberthreat trends also evolved during this period: Below we analyze each of these trends in more detail.

Modern organizations are built on data. It enables collaboration and helps us engage with customers. But that same helpful data is also sprawled across countless apps, making it difficult to secure. Ransomware attacks are on the rise — 57% of security leaders expect ransomware to compromise their organization within the next year — which makes data protection more essential than ever.

A ransomware gang that has been increasingly disproportionately targeting the education sector is the subject of a joint warning issued by the FBI, CISA, and MS-ISAC. The Vice Society ransomware group has been breaking into schools and colleges, exfiltrating sensitive data, and demanding ransom payments. The threat? If the extortionists aren’t paid, you may not be able to unlock your encrypted files, and the attackers may leak the information they have stolen from your servers online.

It is hard to believe, but ransomware is more than three decades old. While many would think that the ransomware mayhem started with the WannaCry attack of 2017, that is simply the most publicized example. Since then, dozens of ransomware strains have been utilized in a variety of cyberattacks.

AT&T Alien Labs has discovered a new malware targeting endpoints and IoT devices that are running Linux operating systems. Shikitega is delivered in a multistage infection chain where each module responds to a part of the payload and downloads and executes the next one. An attacker can gain full control of the system, in addition to the cryptocurrency miner that will be executed and set to persist.

The BlackCat/ALPHV ransomware is a complex threat written in Rust that appeared in November 2021. In this post, we describe a real engagement that we recently handled by giving details about the tools, techniques, and procedures (TTPs) used by this threat actor. Firstly, the attacker targeted an unpatched Microsoft Exchange server and successfully dropped webshells on the machine.

Chris Krebs, former Director of the Cybersecurity and Infrastructure Security Administration (CISA) and the new Chair of Rubrik’s CISO Advisory Board, joined us at FORWARD to discuss ransomware, cyber resilience, and all things data security with co-founder and CTO, Arvind (Nitro) Nithrakashyap. His vast experience working with executives, government officials, and IT experts across the country has given him a unique insight into cybersecurity, which he shared, only at FORWARD.

Attackers have begun using new malware to gain an initial foothold onto compromised networks and systems in recent campaigns. What started as a Trojan malware called Qbot in 2007 has now evolved into Qakbot with new tricks. Qakbot has been active since it was first discovered and continues to threaten financial institutions and individual bank customers. This multi-purpose Trojan malware is designed to steal banking credentials such as login information and passwords.

Coming in with very limited domain knowledge, it was a huge challenge for me to dive in and design product features for highly specialized use cases in the data security space. Chances are, there are a lot of you in UX and Product Designer roles who go through similar experiences when designing enterprise software in niche industries. Over the past several years I've discovered a few strategies that have helped ground me in my work.
