A new investigation by the digital rights research group Citizen Lab has revealed how weaknesses inside global telecom infrastructure were allegedly exploited to secretly monitor mobile phone users in more than ten countries over the past three years.
The findings, reviewed by Haaretz, highlight how parts of the global mobile network system, originally developed decades before smartphones existed, continue to expose users to modern surveillance risks despite the arrival of 4G and 5G technologies.
According to the report, researchers uncovered two separate surveillance operations that appear to be linked to commercial spyware and cyber intelligence vendors selling tracking capabilities to government clients worldwide. One of the operations reportedly used telecom infrastructure connected to Israeli providers 019Mobile and Partner Communications, although both companies denied involvement.
Researchers say the operations relied on weaknesses in SS7, an older telecom signaling protocol used globally to route phone calls, text messages, and roaming traffic between mobile operators. SS7 was designed during a period when telecom networks trusted one another by default, long before today’s cybersecurity threats emerged. Security experts have warned for years that attackers can abuse the protocol to monitor phone activity, intercept communications, or identify a user’s location.
The report states that some surveillance firms were able to impersonate legitimate mobile carriers and gain access to these legacy telecom systems in order to track users internationally. A second operation was reportedly linked to Fink Telecom Services, a Swiss company previously named in a 2023 investigation by Haaretz and Lighthouse Reports involving telecom surveillance services supplied to cyber intelligence vendors, including Rayzone.
Last week, British regulators reportedly moved to ban similar telecom signaling abuse practices, describing them as a major source of malicious activity affecting mobile networks. However, the new findings suggest that even newer systems built for 4G and 5G communications are vulnerable to similar exploitation.
One example highlighted in the report is Diameter, a signaling protocol widely used in 4G roaming and many 5G environments to manage subscriber connectivity and authentication. Although Diameter was introduced with stronger security protections than SS7, researchers found that attackers are still capable of abusing the system to conduct tracking operations.
In the first campaign identified by Citizen Lab, researchers documented more than 500 location-tracking attempts between November 2022 and 2025 across countries including Thailand, Bangladesh, Norway, Malaysia, South Africa, and several African nations. The investigation reportedly began after researchers observed a Middle Eastern businessman being repeatedly tracked over a four-hour period through international telecom queries.
Citizen Lab found that telecom identifiers associated with 019Mobile were used to send location-tracking requests through infrastructure connected to Partner Communications, which supports 019Mobile’s services. Another network route reportedly passed through Exelera Telecom, a communications and cloud services provider that also manages international fiber-optic infrastructure. Exelera did not publicly respond to requests for comment.
019Mobile’s head of security denied involvement and stated that the company operates as a virtual provider using another carrier’s infrastructure rather than maintaining its own roaming agreements. Researchers noted that attackers may have forged the company’s telecom identity to access the network.
Although Citizen Lab did not publicly identify the companies behind the operations, the report referenced several possible actors, including Cognyte. Internal files reviewed by Haaretz reportedly showed that Cognyte’s former parent company, Verint Systems, sold an SS7-based tracking product called SkyLock to a government customer in the Democratic Republic of Congo.
According to the report, SkyLock could reportedly locate mobile devices globally by exploiting telecom roaming systems. The documents also pointed to commercial relationships with telecom operators in Thailand, Malaysia, Indonesia, Vietnam, and Congo, several of which overlap with countries mentioned in the surveillance campaign.
Researchers also uncovered a more advanced surveillance method known as SIMjacking. The technique exploits vulnerabilities inside SIM cards by sending hidden binary text messages containing secret instructions. Once received, the SIM card can silently transmit the device’s location back to the attacker without displaying any visible warning or notification to the user.
Citizen Lab identified more than 15,700 suspected SIMjacking-related tracking attempts since late 2022. Researchers noted that when Haaretz and Lighthouse Reports first exposed Fink Telecom Services in 2023, the company had not yet been linked to the SIMjacking technique.
Cybersecurity experts warn that these attacks are especially concerning because they target weaknesses within telecom infrastructure itself rather than requiring malware installation or phishing attacks on individual devices. Researchers also cautioned that many telecom providers continue operating old and new signaling systems together, creating additional opportunities for attackers to bypass modern protections.
Fink Telecom Services, Exelera Telecom, Verint, and Cognyte did not publicly respond to the allegations referenced in the report. Partner Communications stated that it had no connection to the incident and rejected attempts to associate the company with the activity described by researchers.

As financial institutions continue integrating AI into critical operations, regulators are signaling that stronger technical oversight, faster defensive adaptation, and deeper executive-level understanding of emerging technologies will become essential to maintaining resilience against increasingly sophisticated cyber threats
A newly identified infostealer called Storm has emerged on underground cybercrime forums in early 2026, signalling a change in how attackers steal and use credentials. Priced at under $1,000 per month, the malware collects browser-stored data such as login credentials, session cookies, and cryptocurrency wallet information, then covertly transfers the data to attacker-controlled servers where it is decrypted outside the victim’s system.
This change becomes clearer when compared to earlier techniques. Traditionally, infostealers decrypted browser credentials directly on infected machines by loading SQLite libraries and accessing local credential databases. Because of this, endpoint security tools learned to treat such database access as one of the strongest indicators of malicious activity.
The approach began to break down after Google Chrome introduced App-Bound Encryption in version 127 in July 2024. This mechanism tied encryption keys to the browser environment itself, making local decryption exponentially more difficult. Initial bypass attempts relied on injecting into browser processes or exploiting debugging protocols, but these techniques still generated detectable traces.
Storm avoids this entirely by skipping local decryption. Instead, it extracts encrypted browser files and quietly sends them to attacker infrastructure, removing the behavioural signals that endpoint tools typically rely on. It extends this model by supporting both Chromium-based browsers and Gecko-based browsers such as Firefox, Waterfox, and Pale Moon, whereas tools like StealC V2 still handle Firefox data locally.
The data collected includes saved passwords, session cookies, autofill entries, Google account tokens, payment card details, and browsing history. This combination gives attackers everything required to rebuild authenticated sessions remotely. In practice, a single compromised employee browser can provide direct access to SaaS platforms, internal systems, and cloud environments without triggering any password-based alerts.
Storm also automates session hijacking. Once decrypted, credentials and cookies appear in the attacker’s control panel. By supplying a valid Google refresh token along with a geographically matched SOCKS5 proxy, the platform can silently recreate the victim’s active session.
This technique aligns with earlier research by Varonis Threat Labs. Its Cookie-Bite study showed that stolen Azure Entra ID session cookies can bypass multi-factor authentication, granting persistent access to Microsoft 365. Similarly, its SessionShark analysis demonstrated how phishing kits intercept session tokens in real time to defeat MFA protections. Storm packages these methods into a commercial subscription service.
Beyond credentials, the malware collects files from user directories, extracts session data from applications like Telegram, Signal, and Discord, and targets cryptocurrency wallets through browser extensions and desktop applications. It also gathers system information and captures screenshots across multiple monitors. Most operations run in memory, reducing the likelihood of detection.
Its infrastructure design adds resilience. Operators connect their own virtual private servers to Storm’s central system, routing stolen data through infrastructure they control. This setup limits the impact of takedowns, as enforcement actions are more likely to affect individual operator nodes rather than the core service.
Storm supports multi-user operations, allowing teams to divide responsibilities such as log access, malware build generation, and session restoration. It also automatically categorises stolen credentials by service, with visible rules for platforms including Google, Facebook, Twitter/X, and cPanel, helping attackers prioritise targets.
At the time of analysis, the control panel displayed 1,715 log entries linked to locations including India, the United States, Brazil, Indonesia, Ecuador, and Vietnam. While it is unclear whether all entries represent real victims or test data, variations in IP addresses, internet service providers, and data volumes suggest ongoing campaigns.
The logs include credentials associated with platforms such as Google, Facebook, Twitter/X, Coinbase, Binance, Blockchain.com, and Crypto.com. Such information often feeds into underground credential marketplaces, enabling account takeovers, fraud, and more targeted intrusions.
Storm is offered through a tiered pricing model: $300 for a seven-day trial, $900 per month for standard access, and $1,800 per month for a team licence supporting up to 100 operators and 200 builds. Use of an additional crypter is required. Notably, once deployed, malware builds continue operating even after a subscription expires, allowing ongoing data collection.
Security researchers view Storm as part of a broader evolution in credential theft. By shifting decryption to remote servers, attackers avoid detection mechanisms designed to identify on-device activity. At the same time, session cookie theft is increasingly replacing password theft as the primary objective.
The data collected by such tools often marks the beginning of further attacks, including logins from unusual locations, lateral movement within networks, and unauthorised access patterns.
Indicators of compromise include:
Alias: StormStealer
Forum ID: 221756
Registration date: December 12, 2025
Current version: v0.0.2.0 (Gunnar)
Build details: Developed in C++ (MSVC/msbuild), approximately 460 KB in size, targeting Windows systems
This advent of Storm underlines how cybercriminal tools are becoming more advanced, automated, and difficult to detect, requiring organisations to strengthen monitoring of sessions, user behaviour, and access patterns rather than relying solely on traditional credential protection methods.
Malware that can automatically spread between systems, commonly referred to as worms, has long been a recurring threat in cybersecurity. What makes the latest campaign unusual is not just its ability to propagate, but the decision by its operators to deliberately destroy systems in a specific region. In this case, machines located in Iran are being targeted for complete data erasure, alongside the use of an unconventional control architecture.
The activity has been linked to a relatively new group known as TeamPCP. The group first appeared in reporting late last year after compromising widely used infrastructure tools such as Docker, Kubernetes, Redis, and Next.js. Its earlier operations appeared focused on assembling a large network of compromised systems that could function as proxies. Such infrastructure is typically valuable for conducting ransomware attacks, extortion campaigns, or other financially driven operations, either by the group itself or by third parties.
The latest version of its malware, referred to as CanisterWorm, introduces behavior that diverges from this profit-oriented pattern. Once inside a system, the malware checks the device’s configured time zone to infer its geographic location. If the system is identified as being in Iran, the malware immediately executes destructive commands. In Kubernetes environments, this results in the deletion of all nodes within a cluster, effectively dismantling the entire deployment. On standard virtual machines, the malware runs a command that recursively deletes all files on the system, leaving it unusable. If the system is not located in Iran, the malware continues to operate as a traditional worm, maintaining persistence and spreading further.
The decision to destroy infected machines has raised questions among researchers, as disabling systems reduces their value for sustained exploitation. In comments reported by KrebsOnSecurity, Charlie Eriksen of Aikido Security suggested that the action may be intended as a demonstration of capability rather than a financially motivated move. He also indicated that the group may have access to a much larger pool of compromised systems than those directly impacted in this campaign.
The attack chain appears to have begun over a recent weekend, starting with the compromise of Trivy, an open-source vulnerability scanning tool frequently used in software development pipelines. By gaining access to publishing credentials associated with Node.js packages that depend on Trivy, the attackers were able to inject malicious code into the npm ecosystem. This allowed the malware to spread further as developers unknowingly installed compromised packages. Once executed, the malware deployed multiple background processes designed to resemble legitimate system services, reducing the likelihood of detection.
A key technical aspect of this campaign lies in how it is controlled. Instead of relying on conventional command-and-control servers, the operators used a decentralized approach by hosting instructions on the Internet Computer Project. Specifically, they utilized a canister, which functions as a smart contract containing both executable code and stored data. Because this infrastructure is distributed across a blockchain network, it is significantly more resistant to disruption than traditional centralized servers.
The Internet Computer Project operates differently from widely known blockchain systems such as Bitcoin or Ethereum. Participation requires node operators to undergo identity verification and provide substantial computing resources. Estimates suggest the network includes around 1,400 machines, with roughly half actively participating at any given time, distributed across more than 100 providers in 34 countries.
The platform’s governance model adds another layer of complexity. Canisters are typically controlled only by their creators, and while the network allows reports of malicious use, any action to disable such components requires a vote with a high approval threshold. This structure is designed to prevent arbitrary or politically motivated shutdowns, but it also makes rapid response to abuse more difficult.
Following public disclosure of the campaign, there are indications that the malicious canister may have been temporarily disabled by its operators. However, due to the design of the system, it can be reactivated at any time. As a result, the most effective defensive measure currently available is to block network-level access to the associated infrastructure.
This campaign reflects a convergence of several developing threat trends. It combines a software supply chain compromise through npm packages, selective targeting based on inferred geographic location, and the use of decentralized technologies for operational control. Together, these elements underline how attackers are expanding both their technical methods and their strategic objectives, increasing the complexity of detection and response for organizations worldwide.
A significant shift has occurred in the strategic calculus behind destructive cyber operations in recent years, expanding beyond the confines of traditional critical infrastructures into lesser-noticed yet equally vital ecosystems underpinning modern economies.
State-aligned threat actors are increasingly focusing their efforts on organizations embedded within logistics and supply chain frameworks that support entire industries through their operational continuity. A single, well-placed intrusion at these junctions can have a far-reaching impact on interconnected networks, reverberating across multiple interconnected networks with minimal direct involvement.
Healthcare supply chains, however, stand out as especially vulnerable in this context. As central channels of delivery of care, medical technology companies, pharmaceutical distributors, and logistics companies operate as central hubs for the delivery of care, providing support for large healthcare networks.
The scale of these organizations, their interdependence, and their operational criticality make them high-value targets, which allows adversaries to inflict widespread damage indirectly, without exposing themselves to the immediate impact and consequences associated with attacking frontline healthcare organizations. It is against this backdrop that a less examined yet increasingly consequential risk is becoming increasingly evident one that is not related to adversaries' offensive tooling, but rather to the systems organizations use to orchestrate and secure their own environments.
As part of the evolving force multipliers role of device and endpoint management platforms, designed to provide centralized control, visibility, and resilience at scale, these platforms are now emerging as force multipliers. Several recent cyber incidents have provided urgency to this issue, including the recent incident involving Stryker Corporation, where an intrusion into its Microsoft-based environment caused rapid operational disruptions across the company's global footprint.
In response to the company's disclosure of the breach approximately a week later, the Cybersecurity and Infrastructure Security Agency issued a formal alert stating that malicious activity was targeting endpoint management systems within U.S. organizations.
A broader investigation was initiated after the Stryker event triggered it. Through coordination with the Federal Bureau of Investigation, the agency has undertaken efforts to determine the scope of the threat and identify potential affected entities. As illustrated in mid-March, such access can provide a systemic leverage.
An incident occurred on March 11, 2019, causing Stryker's order processing functions to be interrupted, its manufacturing throughput to be restricted, and outbound shipments to be delayed. These effects are consistent with interference at the management level as opposed to a single, isolated system compromise.
The subsequent reporting indicated the incident may have involved the wiping of about 200,000 managed devices as well as the exfiltration of approximately 50 terabytes of data, indicating that both destructive and intelligence-gathering objectives were involved.
A later claim of responsibility was made by Handala, which described the operation as retaliatory in nature after a strike in southern Iran, emphasizing the growing intersection between geopolitical signaling and supply chain disruption in contemporary cyber campaigns.
During the course of the incident, it became increasingly evident that such a compromise would have practical consequences. Several key operational capabilities, including order processing, manufacturing execution, and distribution, were lost as a result of the intrusion, effectively limiting Stryker Corporation's ability to service demand across a globally distributed network. As a result of this disruption, traceable to Microsoft's environment, supply chain processes were immediately slowed down, creating bottlenecks beyond internal systems that led to downstream delivery commitments.
Consequently, the organization initiated its incident response protocol, undertaking containment and forensic analysis, assisted by external cybersecurity specialists, in order to determine the scope, entry vectors, and persistence mechanisms of the incident. Observations from industry observers indicate that Microsoft Intune may be misused as an integral part of a network attack chain, based on preliminary assessments.
Apparently, Lucie Cardiet of Vectra AI has found that threat actors may have exploited the platform's legitimate administration capabilities to remotely wipe managed endpoints, triggering large-scale factory resets on corporate laptops and mobile devices. The implementation of such an approach is technically straightforward, but operationally disruptive at scale, particularly in environments where endpoint integrity is a primary component of production systems and logistics operations.
As a result of these device resets, widespread reconfiguration efforts were necessary, interrupting the availability of inventory management systems, production scheduling platforms, and coordination tools crucial to ensuring supply continuity.
Applied cumulatively, these disruptions delayed manufacturing cycles and affected the timely processing and fulfillment of orders across multiple facilities, demonstrating the rapid occurrence of tangible operational paralysis that can be caused by control-plane compromises. There is evidence from the incident that the pattern of advanced enterprise intrusions is increasingly characterized by the convergence of compromised privileged identities, trusted management infrastructure, and intentional misuse of administrative functions, resulting in disruption of the enterprise.
In the field of security, this alignment is often referred to as a "lethal trifecta," a technique that enables adversaries to inflict systemic damage without using conventional malware techniques. According to investigators, Stryker Corporation was compromised as a result of an intrusion centered on administrative access to its Microsoft Identity and Device Management stack, allowing attackers to utilize enterprise-approved tools in their operations.
Intune platforms, such as Microsoft's, which provide centralized control over device fleets, are naturally equipped with high-impact capabilities. These capabilities can range from the enforcement of policies to the provision of remote wipe functions that can be repurposed into mechanisms for disruption if commandeered.
Employees have been abruptly locked out of corporate systems across geographical boundaries, suggesting that administrative actions have been coordinated. This is consistent with "living off the land" techniques that exploit native enterprise controls in order to avoid detection and maximize operational consequences. It is evident that the scale of disruption underscores the structural dependence that is inherent within the global healthcare supply chain.
Stryker, one of the most prominent companies in the sector, operates in dozens of countries and employs tens of thousands of people. In the event that internal systems underlying manufacturing and order fulfillment were rendered inaccessible, the effects spread rapidly across the organization's international operations.
Many facilities, including major hubs in Ireland, reported experiencing widespread downtime, with employees being unable to access company network services. In spite of the fact that the company stated that its medical devices continued to function safely in clinical settings due to their segregation from affected corporate systems, the incident nevertheless highlights the fragility of interconnected supply chains.
Medical technology providers serve as critical intermediaries and disruptions at this level can have an adverse effect on distributors, healthcare providers, and ultimately the timeline for delivering patient care. On a technical level, the breach indicates that attacker priorities have shifted from endpoint compromise to identity dominance.
Identity-centric operations are increasingly replacing traditional intrusion models, which typically involve malware deployment, lateral movement, and persistence mechanisms. These adversaries use credential, authentication token, or privileged session vulnerabilities to gain control over the enterprise control planes.
After being embedded within identity infrastructure, attackers are able to interact with administrative portals, SaaS management consoles, and device orchestration platforms as if they were legitimate operators. Because actions are executed through trusted channels, malicious activity is significantly less visible. It is therefore important to note that the extent to which the attackers have affected the network is determined by the scope of privileges that the compromised identities possess.
Additionally, it is evident that the attacker's intent has shifted from financial extortion to outright disruption. Although ransomware continues to dominate the threat landscape, these incidents are more closely associated with destructive operations, which are aimed at disabling systems and degrading functionality rather than extracting payment.
In light of the reported scale of device resets and data exfiltration, it appears the campaign was intended to disrupt operational continuity, echoing tactics employed in previous wiper-style attacks often associated with state-aligned actors. Operations of this type are often designed to disrupt organizations for maximum disruption, rather than to maximize financial gain, and are frequently deployed to signal strategic intent.
As evidenced by the attribution claims surrounding the incident, the group Handala defined the operation within the framework of broader geopolitical tensions, indicating that it was aimed at retaliation. Even if such claims are not capable of being fully attributed to such entities, the narrative is consistent with an observation that private sector entities - particularly those involved in critical supply chains - are increasingly at risk of state-linked cyber activity.
Cyberspace geopolitical contestation is no longer confined to peripheral targets, but encompasses integral elements of healthcare, manufacturing, and logistics. A recalibration of enterprise security priorities is particularly necessary in environments in which identity systems and management platforms serve as the operational backbone. These events emphasize the need to refocus enterprise security priorities.
The tactics that are employed today are increasingly misaligned with defenses centered around endpoint detection and malware prevention. Organizations must instead adopt a security posture that focuses on identity-centric risk management, enforcing strict privilege governance, performing continuous authentication validation, and monitoring administrative actions across control planes at the granular level.
Additionally, it is crucial that enterprise management tools themselves be hardened, ensuring that high impact functions such as remote wipe, policy enforcement, and system-wide configuration changes are subject to layered authorization controls and real-time anomaly detection. For industries embedded in critical supply chains, resilience planning extends to the capability of sustaining operations when control-plane disruptions occur, as well as the prevention of intrusions.
Ultimately, Stryker's incident serves as a reminder that in modern enterprise settings, the most trusted of systems can inadvertently turn into the most damaging failure points-and their secure operation requires a degree of scrutiny commensurate with their impact. It can also be argued that the Stryker incident provides a useful illustration of how modern cyber operations can transcend isolated breaches into instruments that can cause widespread disruptions throughout global networks.
