Now the cybercriminals behind Darkside are utilizing brand-new ransomware with brand-new tools and techniques that make them much more of a risk.

What is Coreid?

Must-read security coverage

In a report released Thursday, security firm Symantec detailed the current activities and techniques utilized by Coreid to take advantage of organizations with ransomware. Also known in some circles as FIN7 or Carbon Spider, Coreid is a ransomware-as-a-service (RaaS) operation that establishes ransomware tools and services and after that gathers cash from affiliates who utilize these tools to perform the actual attacks.

After the Colonial Pipeline incident brought undue attention to Darkside, its creators rebranded their offering as BlackMatter, allowing them to continue business as usual without the publicity surrounding the Darkside name. But in November of 2021, the group closed down its BlackMatter operation in response to pressure from law enforcement authorities. However, the operation quickly resurfaced, this time utilizing the name Noberus to explain its ransomware offering. And it’s Noberus that positions a higher threat with more sophisticated tools and innovations.

How Noberus is more harmful than other ransomware

Initially seen in November of in 2015, Noberus boasts a number of features designed to highlight its superiority over other kinds of ransomware. To challenge its victims and law enforcement, Noberus uses two different file encryption algorithms and four encryption modes, any of which can be used to encrypt stolen files from a victim. The default encryption method uses a procedure called “periodic encryption” to encrypt data rapidly and safely yet at the same time avoid detection.

To extract the taken files, Noberus utilizes a tool called Exmatter, which Symantec states is developed to take particular types of files from selected directories and then submit them to the assailant’s server even before the ransomware is deployed. Constantly being fine-tuned and enhanced, Exmatter can exfiltrate files by means of FTP, SFTP (Protected FTP) or WebDav. It can create a report of all the exfiltrated files processed. And it can self-destruct if run in a non-corporate environment.

Noberus likewise is capable of utilizing info-stealing malware to grab credentials from Veeam backup software application, an information defense and disaster healing item utilized by lots of organizations to keep qualifications for domain controllers and cloud services. Called Infostealer.Eamfo, the malware can link to the SQL database in which the credentials are kept and take them through a specific SQL question.

Profitable affiliates who utilize Noberus to perform attacks also present a higher risk due to the tools at their disposal. While Coreid will get rid of affiliates who aren’t creating enough cash, they’ll reward those who prove successful. Any affiliate who brings in more than $1.5 million gains access to DDoS attack tools, declare phone numbers of victims to call them straight, and free strength attack methods versus specific systems.

“In most methods, this report merely strengthens the fact that while there are a few monolithic ‘full stack’ cybercrime gangs, many players in the cybercriminal community are specialized into different functions,” said Chris Clements, VP of Solutions Architecture for Cerberus Guard. “There are initial access brokers reselling footholds into networks, ransomware as a service developers that develop the tools to escalate benefits, exfiltrate information, and launch mass file encryption operations, and their consumers who utilize those toolsets to extort victims.”

How to secure your organization from ransomware

With advanced tools and techniques utilized by such ransomware as Noberus, how can organizations much better safeguard themselves from attack?

“To stay safe versus such effective tools, organizations need to embrace a true culture of cybersecurity that concentrates on the principles of awareness, avoidance, monitoring, and validation,” Clements stated. “Versus a rapidly progressing risk landscape it’s far more important that defenders focus efforts on avoidance and detection, not against cybercriminal tooling, but rather approaches and behaviors that assailants utilize. Private exploits can alter daily, however the goals of cybercriminals change a lot more gradually. The primary goals of rapidly discovering and exfiltrating sensitive information and introducing mass-scale file encryption campaigns are reputable targets to focus efforts on avoidance and detection.”
