The New Jersey State Bar Association supports more than 18,000 attorneys, judges and legislators in the metropolitan New York City region. From an IT security perspective, our primary goals are to protect the sensitive data of our employees and members, and minimize the disruption to our business caused by cyber-threats.
Over the past few years, our team has become increasingly concerned about the terrifying pace at which the threat landscape is evolving. We’ve seen escalating ransomware attacks, we’ve seen attackers targeting the supply chain and exploiting SaaS platforms like Microsoft 365 and Salesforce. We see new vulnerabilities coming out all the time. On the email side, we see evolving attack techniques, with malicious links hidden in documents so that an email bypasses the first line of defense, or lateral movement against calendar invites.
The pace of attacker innovation tells us one thing: we can’t just protect ourselves against the threats that we know about; we must also prepare for those we don’t know about. What might sound like a paradox is actually achievable with the right approach.
This was one of the factors that drew us to Darktrace two years ago: its ability to learn what’s ‘normal’ for our organization and detect anomalies that indicate a cyber-threat. And it wasn’t long into the deployment that this started to yield strong results, shining a light on new vulnerabilities and activity we didn’t previously know about.
But the other major factor in that purchasing decision was Darktrace’s Autonomous Response capability. Cyber-attacks are no longer controlled by a human from start to finish. Attackers are adopting automation and machine learning to scale up and launch faster and more damaging campaigns.
Our relatively small IT team were in constant action trying to stay on top of some of the threats we faced. But even the best team in the world need to sleep. And we found attackers were taking advantage of this, conducting much of their activity outside of office hours, in the middle of the night or on weekends. This led us to the conclusion that we needed something that could respond autonomously, around the clock, to contain serious emerging threats.
Incorporating Autonomous Response into the security stack
The decision to let an AI make decisions and actively intervene in our environment was not taken lightly and prompted a number of considerations. Some people in our team were sceptical and thought it wouldn’t work, others feared that the AI would replace them and render their jobs redundant. Neither turned out to be the case.
One concern was that the AI would trip up our system, with false positives triggering unwanted actions and resulting in disruption. But after a short learning period and some relatively simple fine-tuning, its actions are now extremely precise, acting only in the case of a serious attack and intervening in a targeted way, blocking only unwanted connections without taking the device offline.
As for the AI making our humans redundant: this hasn’t happened either. We’ve found that the AI augments our team and works alongside them: it does much of the heavy lifting: the tedious, manual work, and it means our team can spend their time on things that matter, being proactive and staying on top of threats rather than always playing catch up.
It’s interesting how over time, Autonomous Response has naturally integrated with our workflow. Our experiences over the last two years have definitely prompted a change in philosophy, from a wariness towards AI to embracing a system where humans and AI work in tandem. We even use the product as an education tool: the information it gives us has become incredibly valuable for junior staff who are still learning how to respond to certain events. We’re at the point now where Darktrace is referred to almost as a sentient being; it has become another member of the team, responding to threats and protecting our business like everyone else.
Expanding Autonomous Response across the enterprise
Once we were confident in the AI’s decision-making and its ability to detect and respond to known and unknown threats around the clock, the next phase was to implement this technology across all parts of the digital estate.
When we moved to a system of remote working following the pandemic, it was important to us that Autonomous Response be brought to remote endpoint devices, so that it could be active in protecting our employees, wherever they were working from. We did already have detection and response in place on the endpoint, but by this point, Darktrace’s Autonomous Response had become so integral to our security posture that we needed to extend it to cover every base.
We also adopted Antigena Email, which uses the same underlying approach to respond to novel threats targeting the inbox, and Antigena SaaS, to respond to account takeovers in Microsoft 365.
Having a single AI approach span multiple silos serves to increase the accuracy of its decision-making: an understanding of endpoint and network traffic can help Antigena Email understand if a link in an email is threatening, for example. Or in the case of account takeover, an unusual SaaS login followed by suspicious email activity can paint a picture of one systematic attack.
The more sophisticated attackers today are unlikely to target just one corner of your digital estate. Having a single AI system connect the dots across cloud, email, network and endpoints puts us in the best possible position.
A crucial layer of defense
I liken the need for Darktrace with the need to wear a seatbelt. You hope that most of the time, you won’t need it. But when the worst happens, it can save you from a potentially fatal threat.
In early 2022 we were targeted by a very targeted, clever attack, in which the attacker adopted a variety of techniques to stay under the radar of the rest of our security stack. It began with a seemingly benign SaaS login from an expected region of the world, but from a different network within that region. We would not have seen this attack without Darktrace connecting multiple subtle anomalies. And we know that if there was some lateral movement later down the line then Antigena would kick in in a variety of different ways to shut the attack down.
As we continue to be targeted by increasingly advanced attackers, this is the kind of insurance we need. Darktrace is not the only tool we use, but it has become the foundation that everything is built on. And with Autonomous Response across our digital estate, we know we have best-in-class protection against novel attacks, no matter where or when they come in.

State of AI Cybersecurity 2026: 77% of security stacks include AI, but trust is lagging
AI is now embedded throughout the cybersecurity stack, but findings from the State of AI Cybersecurity 2026 show that adoption is growing much faster than trust or understanding. As vendors strive to capture market share, security leaders must learn how to distinguish the most valuable solutions from the hype.
AI Insider Threats: How Generative AI is Changing Insider Risk
The blog examines how AI has changed the paradigm of understanding, and dealing with, insider threats. It also explores a defense-in-depth approach and discusses what CISOs and SOC leaders can do to protect their organization from AI insider threats.
Resilience at the Speed of AI: Defending the Modern Campus with Darktrace
Providing university students and faculty with broad access to information, platforms, and public databases is fundamental to learning and research. But that openness also creates greater exposure to cyber threats. In this blog, Irving Bruckstein shares why he deployed Darktrace at three institutions, how behavioral AI helped him achieve an A-rating security posture, and why autonomous detection is essential in an AI-driven threat landscape.
AI is a contributing member of nearly every modern cybersecurity team. As we discussed earlier in this blog series, rapid AI adoption is expanding the attack surface in ways that security professionals have never before experienced while also empowering attackers to operate at unprecedented speed and scale. It’s only logical that defenders are harnessing the power of AI to fight back.
After all, AI can help cybersecurity teams spot the subtle signs of novel threats before humans can, investigate events more quickly and thoroughly, and automate response. But although AI has been widely adopted, this technology is also frequently misunderstood, and occasionally viewed with suspicion.
For CISOs, the cybersecurity marketplace can be noisy. Making sense of competing vendors’ claims to distinguish the solutions that truly deliver on AI’s full potential from those that do not isn’t always easy. Without a nuanced understanding of the different types of AI used across the cybersecurity stack, it is difficult to make informed decisions about which vendors to work with or how to gain the most value from their solutions. Many security leaders are turning to Managed Security Service Providers (MSSPs) for guidance and support.
The right kinds of AI in the right places?
Back in 2024, when we first conducted this annual survey, more than a quarter of respondents were only vaguely familiar with generative AI or hadn’t heard of it at all. Today, GenAI plays a role in 77% of security stacks. This percentage marks a rapid increase in both awareness and adoption over a relatively short period of time.
According to security professionals, different types of AI are widely integrated into cybersecurity tooling:
67% report that their organization’s security stack uses supervised machine learning
67% report that theirs uses agentic AI
58% report that theirs uses natural language processing (NLP)
35% report that theirs uses unsupervised machine learning
But their responses suggest that organizations aren’t always using the most valuable types of AI for the most relevant use cases.
Despite all the recent attention AI has gotten, supervised machine learning isn’t new. Cybersecurity vendors have been experimenting with models trained on hand-labeled datasets for over a decade. These systems are fed large numbers of examples of malicious activity – for instance, strains of ransomware – and use these examples to generalize common indicators of maliciousness – such as the TTPs of multiple known ransomware strains – so that the models can identify similar attacks in the future. This approach is more effective than signature-based detection, since it isn’t tied to an individual byte sequence or file hash. However, supervised machine learning models can miss patterns or features outside the training data set. When adversarial behavior shifts, these systems can’t easily pivot.
Unsupervised machine learning, by contrast, can identify key patterns and trends in unlabeled data without human input. This enables it to classify information independently and detect anomalies without needing to be taught about past threats. Unsupervised learning can continuously learn about an environment and adapt in real time.
One key distinction between supervised and unsupervised machine learning is that supervised learning algorithms require periodic updating and re-training, whereas unsupervised machine learning trains itself while it works.
The question of trust
Even as AI moves into the mainstream, security professionals are eyeing it with a mix of enthusiasm and caution. Although 89% say they have good visibility into the reasoning behind AI-generated outputs, 74% are limiting AI’s ability to take autonomous action in their SOC until explainability improves. 86% do not allow AI to take even small remediation actions without human oversight.
This model, commonly known as “human in the loop,” is currently the norm across the industry. It seems like a best-of-both-worlds approach that allows teams to experience the benefits of AI-accelerated response without relinquishing control – or needing to trust an AI system.
Keeping humans somewhat in the loop is essential for getting the best out of AI. Analysts will always need to review alerts, make judgement calls, and set guardrails for AI's behavior. Their input helps AI models better understand what “normal” looks like, improving their accuracy over time.
However, relying on human confirmation has real costs – it delays response, increases the cognitive burden analysts must bear, and creates potential coverage gaps when security teams are overwhelmed or unavailable. The traditional model, in which humans monitor and act on every alert, is no longer workable at scale.
If organizations depend too heavily on in-the-loop humans, they risk recreating the very problem AI is meant to solve: backlogs of alerts waiting for analyst review. Removing the human from the loop can buy back valuable time, which analysts can then invest in building a proactive security posture. They can also focus more closely on the most critical incidents, where human attention is truly needed.
Allowing AI to operate autonomously requires trust in its decision-making. This trust can be built gradually over time, with autonomous operations expanding as trust grows. But it also requires knowledge and understanding of AI — what it is, how it works, and how best to deploy it at enterprise scale.
Looking for help in all the right places
To gain access to these capabilities in a way that’s efficient and scalable, growing numbers of security leaders are looking for outsourced support. In fact, 85% of security professionals prefer to obtain new SOC capabilities in the form of a managed service.
This makes sense: Managed Security Service Providers (MSSPs) can deliver deep, continuously available expertise without the cost and complexity of building an in-house team. Outsourcing also allows organizations to scale security coverage up or down as needs change, stay current with evolving threats and regulatory requirements, and leverage AI-native detection and response without needing to manage the AI tools themselves.
Preferences for MSSP-delivered security operations are particularly strong in the education, energy (87%), and healthcare sectors. This makes sense: all are high-value targets for threat actors, and all tend to have limited cybersecurity budgets, so the need for a partner who can deliver affordable access to expertise at scale is strong. Retailers also voiced a strong preference for MSSP-delivered services. These companies are tasked with managing large volumes of consumer personal and financial data, and with transforming an industry traditionally thought of as a late adopter to a vanguard of cyber defense. Technology companies, too, have a marked preference for SOC capabilities delivered by MSSPs. This may simply be because they understand the complexity of the threat landscape – and the advantages of specialized expertise — so well.
In order to help as many organizations as possible – from major enterprises to small and midmarket companies – benefit from enterprise-grade, AI-native security, Darktrace is making it easier for MSSPs to deliver its technology. The ActiveAI Security Portal introduces an alert dashboard designed to increase the speed and efficiency of alert triage, while a new AI-powered managed email security solution is giving MSSPs an edge in the never-ending fight against advanced phishing attacks – helping partners as well as organizations succeed on the frontlines of cyber defense.

When Open Source Is Weaponized: Analysis of a Trojanized 7 Zip Installer
Background of the malicious 7-Zip installer, and assessing its Impact
Early in 2026, external researchers disclosed a malicious distribution campaign leveraging a trojanized installer masquerading itself as a legitimate 7‑Zip utility. Evidence suggests the campaign was active as of January 2026, during which victims were served a fake installer from 7zip[.]com, a highly convincing typo-squatted domain impersonating the official 7‑Zip distribution site (7-zip[.]org).
Initial access is typically achieved through social engineering and search‑engine abuse, including YouTube tutorial content that explicitly referenced the impersonated domain as the download source. Notably, several reports observed the installer delivered a modified but functional build of 7‑Zip (7zfm.exe) to reduce suspicion and preserve expected user behavior.
However, the installer also dropped additional payloads, such as Uphero.exe, hero.exe, and hero.dll, which are not part of the legitimate 7‑Zip software package. Once installed and executed, these payloads allow the attacker to establish persistence and configure the infected host as a proxy node under their control. This facilitates malicious activities such as traffic relaying, anonymizing infrastructure, and the delivery of secondary payloads [1] [2].
Overall, this attack illustrates a proxyware-style attack that abuses implicit trust in widely deployed third‑party tools while exploiting unconventional delivery vectors such as instructional media. By closely imitating legitimate software behavior and branding, the threat actors significantly reduced user suspicion and increased the likelihood of widespread, undetected compromise.
Threat overview
Darktrace observed multiple customers affected by the malicious 7‑Zip installer between January 12 and January 22, impacting organizations across the Americas (AMS), Asia‑Pacific & Japan (APJ), and Europe, the Middle East, and Africa (EMEA) regions. The activity targeted customers across various sectors, including Human health and social work activities, Manufacturing, Education, and Information and communication.
The following use case highlights a device on one customer network making external connections associated with malicious 7-Zip update activity observed between January 7 and January 18, 2026. This behavior included connectivity to the malicious domain 7zip[.]com, followed by command-and control (C2) activity involving "smshero"-themed domains, as well as outbound proxy connections over ports 1000 and 1002.
Initial Connectivity to 'update[.]7zip[.]com':
Figure 1: Initial Beaconing to Young Endpoint alert behavior, involving the known tunnel/proxy endpoint ‘79.127.221[.]47’.
Starting on January 7, Darktrace / NETWORK detected the device making repeated beaconing connections to the endpoint 79.127.221[.]47 over the destination port 1000. The use of this port aligns with open-source intelligence (OSINT) reporting that hero[.]exe establishes outbound proxy connections via non-standard ports such as 1000 and 1002 [1].
Figure 2: Darktrace observed TLS beaconing alerts to the known trojanized installer, update[.]7zip[.]com · 98.96.229[.]19, over port 443 on January 7th.
Later the same day, the device initiated TLS beaconing to the endpoint update.7zip[.]com. This is more than likely a common source of compromise, where victims unknowingly installed a modified build of the tool alongside additional malicious components. The campaign then progressed into the next attack phase, marked by established connectivity to various C2 domains.
Beaconing Activity to "smshero"-themed domains
Darktrace subsequently observed the same infected device connecting to various C2 domains used to retrieve configuration data. As such, these external hostnames were themed around the string “smshero”, for example ‘smshero[.]co’.
Figure 3: On January 8th, Darktrace observed SSL beaconing to a rare destination which was attributed to a known ‘config/control domain’, nova[.]smshero[.]ai.
The following day, on January 8, the device exhibited its first connectivity to a "smshero"-themed endpoint, which has since been identified as being associated with rotating C2 servers [1] [3]. Similar beaconing activity continued over the following days, with Darktrace identifying C2 connectivity to update[.]7zip[.]com over port 443, alongside additional connections to “smshero”‑themed endpoints such as zest.hero-sms[.]ai, flux.smshero[.]cc, and glide.smshero[.]cc between January 9 and January 15.
Figure 4: Darktrace later observed continued beaconing alerts over a 4-day interval to additional rare destinations attributed to a known ‘config/control domain’, zest[.]hero-sms[.]ai & glide[.]smshero[.]cc.
Proxied connectivity over destination ports
The primary objective of this campaign is believed to be proxyware, whereby third-party traffic is routed through victim devices to potentially obfuscate malicious activity. Devices were also observed communicating with rare external IPs hosted on Cloudflare and DataCamp Limited ASNs, establishing outbound proxy connections over the non-standard ports 1000 and 1002 [1].
OSINT sources also indicate that connections over these ports leveraged an XOR-encoded protocol (key 0x70) designed to obscure control messages. While the end goal of the campaign remains unclear, residential proxy networks can be abused to evade security rules and facilitate further unauthorized activities, including phishing and malware distribution [1][3].
Specifically, on January 8, Darktrace observed the device engaging in low-and-slow data exfiltration to the IP 79.127.221[.]47, which had first been observed the previous day, over port 1000. Proxyware typically installs an agent that routes third‑party traffic through an end-user’s device, effectively turning it into a residential proxy exit node. This activity likely represents the system actively communicating outbound data to an entity that controls its behavior.
Figure 5: Darktrace later observed a ‘Low and Slow Exfiltration to IP’ alert, involving the known tunnel/proxy endpoint ‘79.127.221[.]47’.
Similar activity continued between January 10 and January 18, with Darktrace detecting threat actors attempting to exfiltrate significant volumes of data to 79.127.221[.]47 over destination port 1000.
Throughout the course of this incident, Darktrace’s Cyber AI Analyst launched several autonomous investigations, analyzing each anomalous event and ultimately painting a detailed picture of the attack timeline. These investigations correlated multiple incidents based on Darktrace detections observed between January 7 and January 19. Cyber AI Analyst identified anomalous variables such as repeated connections to unusual endpoints involving data uploads and downloads, with particular emphasis on HTTP and SSL connectivity.

Darktrace’s Autonomous Response
At several stages throughout the attack, Darktrace implemented Autonomous Response actions to help contain the suspicious activity as soon as it was identified, providing the customer’s security team with additional time to investigate and remediate. Between January 7 and January 18, Darktrace blocked a wide range of malicious activity, including beaconing connections to unusual endpoints, small data exfiltration attempts, and larger egress efforts, ultimately preventing the attacker from progressing through multiple stages of the attack or achieving their objectives.

Conclusion
The malicious 7‑Zip installer underscores how attackers continue to weaponize trust in widely used, legitimate software to gain initial access while evading user suspicion. By exploiting familiar and commonly installed services, this type of attack demonstrates that even routine actions, such as installing compression software, can become high‑risk events when defenses or user awareness are insufficient.
This campaign further emphasizes the urgent need for strict software validation and continuous network monitoring. Modern threats no longer rely solely on obscure tools or overtly malicious behavior. Instead, they increasingly blend seamlessly into everyday operations, making detection more challenging.
In this case, Darktrace / NETWORK was able to identify the anomalous activity and Autonomous Response actions in a timely manner, enabling the customer to be quickly notified and providing crucial additional time to investigate further.
In summary, the abuse of a trojanized 7‑Zip installer highlights a concerning shift in modern threat tactics, where trusted and widely deployed tools can serve as primary delivery mechanisms for system compromise. This reality reinforces that proactive detection, continuous monitoring, and strong security awareness are not optional but essential.
