ThreatAI Analysis

Compiled from this incident record and the threat intelligence profile for Nitrogen. Figures and technique mappings are quoted from the source data, not inferred.

About the Nitrogen group

Nitrogen began as a malware loader in 2023 used to deliver BlackCat/ALPHV ransomware, then evolved into a fully independent ransomware operator by mid-2024, operating its own strain derived from leaked Conti 2 builder code and conducting double-extortion attacks primarily linked to Eastern European infrastructure. Nitrogen has listed 48 victims since March 2023.

How Nitrogen is documented to operate

Drive-by Compromise T1189 Initial Access

Adversaries may gain access to a system through a user visiting a website over the normal course of browsing. Multiple ways of delivering exploit code to a browser exist (i.e., Drive-by Target), including: A legitimate website is compromised, allowing adversaries to inject malicious code Script files served to a legitimate website from a publicly writeable cloud storage bucket are modified by an adversary Malicious ads are paid for and served through legitimate ad providers (i.e., Malvertising) Built-in web application interfaces that allow user-controllable content are leveraged for the insertion of malicious scripts or iFrames (e.g., cross-site scripting) Browser push notifications may als…

Command and Scripting Interpreter T1059 Execution

Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries. These interfaces and languages provide ways of interacting with computer systems and are a common feature across many different platforms. Most systems come with some built-in command-line interface and scripting capabilities, for example, macOS and Linux distributions include some flavor of Unix Shell while Windows installations include the Windows Command Shell and PowerShell. There are also cross-platform interpreters such as Python, as well as those commonly associated with client applications such as JavaScript and Visual Basic.

MITRE ATT&CK reference →
Scheduled Task/Job T1053 Execution Persistence

Adversaries may abuse task scheduling functionality to facilitate initial or recurring execution of malicious code. Utilities exist within all major operating systems to schedule programs or scripts to be executed at a specified date and time. A task can also be scheduled on a remote system, provided the proper authentication is met (ex: RPC and file and printer sharing in Windows environments). Scheduling a task on a remote system typically may require being a member of an admin or otherwise privileged group on the remote system. Adversaries may use task scheduling to execute programs at system startup or on a scheduled basis for persistence.

Incident Analysis

Connor Co was targeted by Nitrogen ransomware, one of the most active ransomware groups in our database with 48 confirmed victims globally. The attack was disclosed on January 27, 2026, when Connor Co appeared on the group's dark web leak site.

Connor Co is based in United States , operating in the Business Services sector. United States ranks #1 globally for ransomware attacks, with 9,425 victims in our database.

Sector context: Business services firms often have access to multiple client environments, making them high-value pivot points for ransomware operators seeking to maximise impact across multiple victim organisations.

Nitrogen typically employs a double extortion model: first exfiltrating sensitive data from the victim's systems, then deploying ransomware to encrypt files. Victims face two simultaneous threats — paying to restore access and paying to prevent publication of stolen data. The group's leak site publishes victim names and exfiltrated data as leverage.

Data source: This incident record is sourced from public ransomware group leak site disclosures aggregated via the ransomware.live API. Disclosure date reflects when the victim was published on the leak site, which may differ from the initial date of compromise. This platform does not publish or link to stolen data. Last data update: Sep 6, 2026 20:00 UTC.

Frequently Asked Questions

Which ransomware group attacked Connor Co?

Connor Co was attacked by Nitrogen ransomware. Nitrogen is one of the most active ransomware groups, having claimed 48 victims globally. The group typically employs a double-extortion model: encrypting the victim's files and threatening to publish stolen data.

When did the Connor Co ransomware attack occur?

The ransomware attack on Connor Co was disclosed on January 27, 2026. This date reflects when the victim was published on the threat group's leak site, which may differ from the actual date of initial compromise.

What data was stolen in the Connor Co ransomware attack?

The specific data stolen from Connor Co has not been independently verified by this platform. Ransomware groups typically exfiltrate data before encrypting systems and use the threat of publication to pressure victims. As a Business Services organisation, Connor Co likely held sensitive business data, client information, and operational records.

How can organisations protect against Nitrogen attacks?

To defend against Nitrogen and similar threat actors, organisations should: maintain regular offline backups tested for restoration; implement network segmentation to limit lateral movement; deploy multi-factor authentication on all remote access; use endpoint detection and response (EDR) tools; conduct regular phishing and security awareness training; and monitor threat intelligence feeds for indicators of compromise (IOCs) associated with active groups.
