Ransomware attacks are as pervasive as ever, with new data demonstrating just how impactful the attacks really are. If you’re one of the lucky few organizations that hasn’t fallen victim to a ransomware attack, consider yourself lucky. According to the 2023 Ransomware Trends Report from backup vendor Veeam, the vast majority of organizations (85%) have experienced a ransomware attack. And while that number is pretty shocking, that’s not the worst of it.

These, as well as other notable trends from the previous quarter, are discussed in the report, Q1 2023 Threat Landscape Report: Ransomware Groups Splinter, Swarm Professional Services.

The purpose of the Netskope Threat Labs News Roundup series is to provide enterprise security teams an actionable brief on the top cybersecurity news from around the world. The brief includes summaries and links to the top news items spanning cloud-enabled threats, malware, and ransomware.

My analysis of this year’s newly-released Verizon Data Breach Investigations Report begins with ransomware findings that point back to users as a big problem. If you only read one report each year to give you an idea of what’s going on with cyber attacks, it’s Verizon’s Data Breach Investigations Report (DBIR). Each year, analysts sort through tens of thousands of data breach incidents (some successful, some not) and identify the attack patterns.

On the surface, ransomware – malicious software designed to block access to a computer system until a sum of money is paid – appears to be off to yet another ruthless start in 2023 as one of the leading types of malware. Recent victims of public attacks in North America include industries such as health care, communication, education, and even government offices and municipalities.

The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) has identified and designated Mikhail Matveev for his role in ransomware attacks back 2021. When the U.S. sanctions a country, a business, or a group, the intent is to A) confiscate any and all property owned by the designee within the U.S. or in the possession of a U.S. person, and B) add the designee to the Specially Designated Nationals and Blocked Persons (SDN) List.

Most malware security researchers encounter in the wild is written in C or C++. These languages provide low-level system access and control, plus performance, allowing threat actors to create highly efficient and stealthy code. But that doesn’t mean cybercriminals are limited to those two languages. SecurityScorecard recently reverse-engineered the Vjw0rm worm written in JavaScript and the Java-based STRRAT remote access trojan (RAT).

SeroXen is a new Remote Access Trojan (RAT) that showed up in late 2022 and is becoming more popular in 2023. Advertised as a legitimate tool that gives access to your computers undetected, it is being sold for only $30 for a monthly license or $60 for a lifetime bundle, making it accessible.

The US healthcare sector continues to be aggressively targeted by ransomware operators. Royal and BlackCat are two of the more recent – and highly sophisticated – ransomware threats. These two new flavors of ransomware pose serious potential impacts on the healthcare sector, but there are appropriate mitigation and defense strategies that organizations can take to protect against them.
