No Place to Hide: Following a Serial Ransomware Affiliate from LockBit, Black Basta, and Qilin to The Gentlemen

Key Findings

  • In early February 2026, Silent Push Analysts detected a Cobalt Strike Command and Control (C2) configuration tied to a ransomware affiliate using CountLoader and Cobalt Strike payloads with a unique watermark.
  • As we reviewed the Check Point Research incident response report on The Gentlemen Ransomware-as-a-Service (RaaS), we detected the mentioned Cobalt Strike IP address, which we had found 2.5 months before public reporting, and attribute this incident to the same ransomware actor that we discussed in our CountLoader research. 
  • Our Indicators of Future Attack® (IOFA) block downstream attacks involving Cobalt Strike, which ransomware actors and Advanced Persistent Threats (APTs) often leverage.
  • We previously reported identifying more than 10,000 infected IP addresses as part of the RaaS-related SystemBC botnet malware family in our February 2026 blog and March 2026 client report.

We urge all organizations to take protective measures by setting up automated blocking via integrating the Cobalt Strike IOFA feed directly into their firewall, SIEM, or EDR via an API or STIX/TAXII feed.

Executive Summary

Silent Push has been tracking ransomware threat actors for several years. Following the deep-dive research and reporting in July-August 2025, chronicling our discovery of a new malware loader we named “CountLoader, on September 18, 2025, we published a public blog, “CountLoader: Silent Push Discovers New Malware Loader Being Served in 3 Different Versions,” sharing our findings.

Our analysis highlights a critical intersection between malware infrastructure and specific threat actors: the discovery of Cobalt Strike watermarks (1473793097) and (1357776117). These unique license identifiers provide the technical “fingerprint” to link the activity directly to a ransomware affiliate with verifiable ties to the Black Basta, LockBit, and Qilin attacks.

We were inspired by the recent Digital Forensics and Incident Response (DFIR) report from Check Point, which highlights an intrusion involving SystemBC and Cobalt Strike. From this, our research team was able to tie our earlier ransomware affiliate findings to the Gentlemen RaaS.

Since Cobalt Strike is often used by APTs and ransomware actors, we urge organizations to block infrastructure related to our Cobalt Strike IOFA feeds.


Incident

The Check Point DFIR report highlights the use of a Cobalt Strike C2 at IP address 91.107.247[.]163, tied to the intrusion and eventual ransomware deployment by the RaaS, The Gentlemen.

The Cobalt Strike C2 IP was flagged as an IoFA in our report on February 8, 2026.

Screenshot of Silent Push Total View of IP Address 91.107.247[.]163
Silent Push Total View of IP address: 91.107.247[.]163

We found the indicator using the same unique Cobalt Strike detection method we developed in our analysis of CountLoader. We can attribute this ransomware intrusion with high confidence to the same ransomware actor that is part of the Black Basta, LockBit, and Qilin ransomware groups. Additionally, with the DFIR report from Checkpoint, we can tie this same actor to also be leveraging The Gentlemen ransomware.

Our unique detection methodology ensures that our tracking remains persistent even when a threat actor pivots between ransomware groups; by identifying the individual behind the keyboard rather than just the brand they serve, we maintain a high-confidence trail on this affiliate throughout their three-year tenure across LockBit, Black Basta, Qilin, and now The Gentlemen.


Historic Incidents

In our CountLoader blog, we highlight external research tied to the observed Cobalt Strike watermark (and, by extension, the CountLoader campaign we have been tracking) directly to BlackBasta, Qilin, and LockBit ransomware activity. To provide additional background, we are listing several external sources to highlight the historical trail of this threat actor (below):

Welcome to the Pivot Penalty: How Tool Sprawl Kills SOC Team Response Times & Keeps IR Teams Reopening the Same Incident

Security teams know the familiar routine: an alert triggers in the Security Information and Event Management (SIEM) system, prompting a manual scramble to determine if the indicator is malicious. A series of “Browser Tab Olympics” ensues as team members rush to pivot across multiple point tools, refresh external threat feeds, and cross-reference internal spreadsheets to investigate a single observable. Welcome to the hidden cost of tool integration chaos, colloquially known among defenders as the “Pivot Penalty.”

Technical truth scattered across disconnected silos 

When an organization’s data lives across separate SIEMs, threat intelligence platforms, and EDR tools, there is no single source of context. Investigations slow down, and both Mean Time to Detect (MTTD) and Mean Time to Respond (MTTR) suffer. SOC analysts lose time to manual legwork, and Incident Response (IR) teams frequently revisit the same incident, trying to understand the full scope of a threat.

According to IBM’s 2025 Cost of a Data Breach Report, it takes organizations an average of 241 days to identify and contain a breach, a nine-year low, with the global average breach costing $4.44 million. And in the US, that number climbs even higher: American organizations now face a record average of $10.22 million per breach. Every day of delay compounds the damage.


Fragmentation Frustration

According to the Panaseer 2022 Security Leaders Peer Report, the average organization manages 76 security tools, a 19% increase driven by cloud adoption and the shift to remote work. While each tool was purchased to protect, together, they often create a significant visibility gap. Teams burn valuable hours manually reconstructing data that their security stack should be handling automatically.

That manual reconstruction is a workflow bottleneck, and the human cost is real. According to a Tines report, 71% of SOC analysts report burnout, with alert fatigue cited as a primary driver. The SANS 2024 SOC Survey found that 66% of SOC teams say they cannot keep pace with the volume of alerts they receive. When senior analysts spend their time on manual research rather than strategic threat hunting, teams feel perpetually behind, and turnover follows.

The Core Blind Spot

Most traditional security solutions focus on internal telemetry or the artifacts of past failures, known as Indicators of Compromise (IOCs). The problem is that IOCs only reflect what has already happened. They are a record of a match you may have already lost.

Legacy tools miss the preparation phase entirely, forcing organizations into a reactive race against a fully deployed adversary. Without upstream visibility into how adversaries build and stage their infrastructure, teams remain locked in a cycle of responding to alerts long after the groundwork for an attack has been laid.


Eliminate the Pivot Penalty with the Context Graph

Effective defense means identifying adversarial behavior earlier, not simply reacting faster. We remove the pivot penalty by doing the correlation work before your investigation begins.

Our platform is built on the Context Graph, an engine that continuously maps the global internet dataset to identify adversary infrastructure as it is being staged. It automatically pre-correlates technical relationships across active DNS records, WHOIS history, SSL certificates, and web content.

When management patterns emerge that match the way adversaries build and operate campaigns, the Context Graph converts them into Indicators of Future Attack® (IOFA): verified signals of a staging ground that exists right now, before it has been used against anyone.

The results speak for themselves. In a real-world deployment at a Fortune 500 media and entertainment company, our platform provided an average of 104 days of detection lead time, with a median lead time of 117 days. In some cases, the lead time exceeded 200 days. Threats from groups including FIN7, Lazarus, and Sapphire Sleet were identified in our dataset months before those indicators appeared in the customer’s SIEM.

Instead of manually connecting signals across tools, we consolidate more than 10 data types into a single view, enriching observables with 70 to 100 or more contextual attributes and proprietary risk scores. This eliminates manual legwork and lets teams link a single indicator to an entire adversary campaign in seconds rather than minutes.

By moving from probability-based guessing to deterministic technical truth, security teams can achieve three specific outcomes:

Accelerated triage. Replace manual data gathering with single-click verification of any IP address or domain.

Reduced alert noise. Suppress low-fidelity signals and focus energy only on verified attacker-controlled infrastructure.

Neutralize before compromise. Identify malicious management patterns during the staging phase to block threats before they reach your perimeter.

Moving left of boom, putting strategy in place before a breach occurs, is foundational to modern defense. By eliminating tool sprawl and the pivot penalty that comes with it, teams can finally give their analysts the capacity to focus on strategic hunting rather than manual data entry.

FAQs

What is the pivot penalty in a security operations center? 

The pivot penalty is the time lost when analysts move between different security tools to verify a single alert. According to the Panaseer 2022 Security Leaders Peer Report, organizations manage an average of 76 security tools, forcing teams to manually cross-reference data across SIEMs, spreadsheets, and threat feeds. This fragmented process slows investigations and contributes to analyst burnout.

How does tool sprawl affect incident response times? 

Tool sprawl increases MTTD and MTTR by creating data silos. According to the IBM 2024 Cost of a Data Breach Report, organizations take an average of 258 days to identify and contain a breach. Analysts spend hours manually reconstructing data because technical context is scattered across disconnected platforms, giving adversaries more time to operate undetected.

What are Indicators of Future Attack (IOFA)? 

Indicators of Future Attack are proactive signals that identify malicious infrastructure during the setup phase. Unlike traditional indicators that record past breaches, IOFAs expose attacker staging grounds before weaponization, enabling security teams to block threats weeks or months before an attack launches.

How does the Context Graph reduce manual data gathering? 

The Context Graph continuously maps global internet data to identify patterns of attacker behavior. It connects billions of signals across DNS records, certificates, and web content, providing analysts with deterministic technical truth without requiring manual pivots across point tools. In one documented deployment, this translated into a median 117-day detection lead time over traditional SIEM-based approaches.

Why is deterministic data better than probability scores? 

Deterministic data gives a clear answer rather than an inferred score. Probability scores generate large volumes of low-confidence alerts, contributing to noise and analyst fatigue. Verified technical context enables organizations to automate defensive actions with confidence, as findings are based on known adversary infrastructure.

What is the Silent Push Context Graph? Preemptive Cyber Defense Explained

Threat actors have a process, and most security tools are designed to respond to it after the fact. Preemptive cyber defense changes that by identifying adversary infrastructure during the preparation phase, before anything malicious lands.

Before a phishing campaign reaches an inbox, before a command-and-control (C2) server receives its first callback, there is a period of preparation. Infrastructure gets registered and aged. Servers come online, DNS records resolve, and certificates rotate. The attacker’s process is methodical, and because it is methodical, it leaves a trail.

Most security tools are watching the wrong part of that timeline. By the time an Indicator of Compromise (IOC) surfaces in your stack, the attacker has already completed the preparation phase. The infrastructure has been live and operational for weeks. Your tools are doing their job, just after the window to act has already closed.

We built the Silent Push Context Graph for that window.

The Context Graph continuously maps the internet’s DNA, tracking how infrastructure is created, changed, and managed across DNS, WHOIS, certificates, and hosting data every single day. Critically, it analyzes everything, not just known-bad infrastructure. Future threats do not emerge from known-bad sources alone. They grow from what looks ordinary today. Think clean domains on legitimate hosting providers, servers that have not yet received a single malicious instruction, certificates that look identical to thousands of others…

Threat actors deliberately stage their operations inside normal-looking infrastructure because they know most tools are only watching the parts of the internet that have already been flagged. The Context Graph watches everything, because that is the only way to see what is coming.

Stages of the Context Graph preemptive cyber defense
Three stages of the Silent Push Context Graph; Collect, Build Context and Operationalize.

When management patterns emerge that match the way adversaries build and operate campaigns, the Context Graph turns them into Indicators of Future Attack® (IOFA): verified signals of a staging ground that exists right now, before it has been used against anyone.

Unlike risk scores based on domain age or registration history, IOFAs are grounded in how infrastructure is actively being built and managed, following the same operational tactics, techniques, and procedures (TTPs) that adversaries use every single time. Even when they rotate hosting providers or change subnets, the process stays consistent. The Context Graph knows those processes, which is how it surfaces what is coming before it arrives.

For security teams, this changes the fundamental shape of defense. Instead of catching up to the last campaign, you have lead time on the next one. Instead of remediating what has already happened, you block the staging ground before the campaign ever leaves it.

A Source of Truth Your Security Workflows Can Trust

Security teams are increasingly running automated workflows and AI-assisted triage inside their SIEM and SOAR platforms. The quality of those workflows depends entirely on the quality of the data feeding them. Noisy probability scores and unverified threat feeds produce unreliable automation: false positives that burn analyst time, automated responses that act on the wrong signals, and AI agents that draw flawed conclusions from data without clear provenance.

Our platform was built to be machine-consumable from the ground up. Every signal carries clear data provenance. The APIs are designed explicitly for automated triage. When your security workflows reason from deterministic signals rather than probability guesses, they stop generating noise and start taking actions you can trust. For teams building agentic security workflows, the Context Graph provides the kind of reliable, pre-correlated intelligence that makes safe automation possible.

The Context Graph for AI Workflows & Agentic Security
The Context Graph for AI & Agentic Security

Here is what that looks like in practice for SOC and IR teams.

  • SOC teams: automated triage and noise suppression. Automated workflows can consume the Context Graph directly into SIEM or SOAR platforms to automatically validate, enrich, and act on alerts. The Threat Check API provides an instant, deterministic true or false answer on any indicator, eliminating manual cross-referencing entirely. Instead of analysts spending hours pivoting between tools to verify a single alert, the enrichment happens automatically and only verified threats reach the queue. Mean time to detect and mean time to triage both drop significantly.
  • IR teams: instant scoping and complete eradication. During an active incident, automated systems leveraging the Context Graph can take a single IOC and immediately pivot to map the adversary’s entire infrastructure footprint. Connected DNS history, certificate chains, and IP clusters surface in seconds rather than hours. IR teams can generate comprehensive blocklists that cover the full scope of the adversary’s operation, not just the entry point they found first, which is what prevents the same attacker from returning through infrastructure you missed.
  • Blocking pre-weaponized threats automatically. Because the Context Graph operates upstream in the attack lifecycle, automated workflows can operationalize IOFAs to neutralize staging infrastructure before an attack ever launches. Instead of automating the response to threats that have already reached your perimeter, you automate the prevention of threats that have not arrived yet.
Early detection advantage with Silent Push for SOC and IR teams
Silent Push Threat Check Data from 2025

The distinction matters. If your security automation is focused solely on clearing alert queues faster, you are still playing the attacker’s game, just at greater speed. Embedding the Context Graph into your workflows moves your automation to a point in the timeline where the adversary still has options you can take away.

How the Context Graph Fits Into Your Security Stack

The Context Graph is not a replacement for the tools your team already uses. Historical threat intelligence, internet scanning, noise filtering: these are real capabilities and they belong in a mature security stack. What none of them cover is the preparation phase, the window between when an adversary starts building their infrastructure and when it goes active.

Preemptive cyber defense does not replace legacy security. It fills the gap that legacy security was never designed to cover.

The Context Graph integrates directly into existing SIEM, SOAR, and TIP workflows via a fully API-first architecture, feeding verified indicators into the platforms your team already works in. Your analysts spend less time pivoting between systems and more time acting on intelligence that has already been correlated and verified.

Exposing Attacks That Haven't Happened Yet

Fast Company Recognition Underscores Silent Push Preemptive Cyber Defense

Silent Push has been honored with the inclusion in the Fast Company feature on the top 50 of “The most innovative cybersecurity companies of 2026.”

Such recognition of innovation alongside some of the most groundbreaking organizations is a welcome accolade for the Silent Push team’s commitment to preemptive cyber defense and encourages it to stay the course in defining this new security technology. 

Silent Push Co-Founder and CEO Ken Bagnall acknowledged both the Silent Push team and its users:

“Huge congratulations to our incredible team, whose dedication to preemptive defense makes this possible. We’d also like to thank our customers for their continued trust and partnership.”

The Fast Company article points out that protecting data was difficult enough when (malicious) hackers were human. Now, generative AI further tilts the playing field, emboldening attackers to continually evolve to evade defenders.

The article continues, stating that some “Companies’ CEOs insist that good cybersecurity is no longer a cost center but a revenue accelerator—helping to make enterprises’ AI systems stronger, instilling trust, and speeding up usage.” It also takes the position that “Weak security weakens the already fragile sense of trust many of us have around AI…Just one gnarly hack or leak by an AI agent could be enough to squash trillion-dollar dreams of adoption.” 


Detect Adversary Infrastructure In Staging, Before It Impacts Your Organization

Legacy security solutions cannot keep ahead of threat actors. Silent Push technology builds on the success of traditional defense methods, ultimately evolving the security stacks of modern organizations with solutions that neutralize threats before they compromise networks.

Silent Push is continually improving modern threat defense, helping organizations stay ahead of threats with our Indicators of Future Attack® and innovative solutions such as Traffic Origin.

Traffic Origin

Trust is a liability in an era where it only costs a few dollars to rent domestic identities and clean residential IPs. Accurate compliance requires more than simply checking a passport; it requires verifying how connections behave on both physical and technical levels. Without the ability to identify upstream points of origin, defensive readiness remains reactive and incomplete, leaving organizations at risk of missing critical windows to block professional fraudsters and “invisible insiders” before they slip past existing security measures.

Silent Push Traffic Origin unmasks deceptive network paths that operatives use to hide their true location. We help you spot the residential proxies and suspicious connection patterns that state-sponsored groups use to bypass traditional geofencing and let you flag high-risk infrastructure and individuals before an attack occurs.

We use a proprietary global observation network to analyze traffic signals, enabling the platform to identify the countries associated with an IP address. This reveals the true physical origin of web traffic, not just where a proxy server sits.

By providing the visibility needed to ensure your KYC (Know Your Customer), AML (Anti-Money Laundering), and fraud workflows are grounded in technical truth rather than digital deception, Traffic Origin can help protect your organization.

Traffic Origin complements our proprietary residential proxy data, which identifies tens of millions of residential proxy IPs and their service providers. Together, these two solutions can help customers differentiate between innocuous residential IPs and those rented for global criminal use.

Exciting Developments on the Horizon

Working to shape a safer today and tomorrow, we recently updated the Silent Push platform with new search capabilities and a what’s new section to see the latest enhancements at a glance.

In the coming weeks, we will be sharing new developments on our unique AI-powered technology and how it provides deterministic certainty in place of typical cybersecurity guesswork.
