WhatsApp 0-Day Exploited in Targeted Attacks on Mac and iOS Platforms

 


Providing a fresh reminder of the constant threat to widespread communication platforms, WhatsApp has disclosed and patched a vulnerability affecting its iOS and macOS applications. The vulnerability has already been exploited in real-world attacks, according to WhatsApp, which warns it may already have been exploited in the past. 

It has a CVSS score of 5.4 and is tracked as CVE-2025-55177. The vulnerability is caused by an insufficient level of authorisation when handling linked device synchronization messages. As a result of the vulnerability, WhatsApp has warned that a malicious actor could potentially compromise the security of users by manipulating content processing using arbitrary URLs on the target device. 

In a statement, the Meta-owned company credited its in-house security team with discovering and analyzing this bug, which is thought to have been exploited in combination with a recently revealed Apple zero-day vulnerability as part of targeted attacks on the company. The incident was deemed to be the result of an "advanced spyware campaign" by Donncha Cearbhaill of Amnesty International's Security Lab, which notes it had been active for approximately 90 days and used zero-click delivery techniques. 

Through this technique, attackers were able to spread malicious exploits through WhatsApp without requiring any interaction from the victim, allowing them to steal data from Apple devices silently and raising serious concerns about the resilience of even highly secure platforms. By way of spokesperson Margarita Franklin, Meta, the parent company of WhatsApp, confirmed that the flaw had been identified and patched several weeks ago, with notification sent to less than 200 users who had been affected. 

Even though the company has not attributed the operation to any specific threat actor or spyware vendor, the lack of attribution highlights how difficult it may be to trace such sophisticated campaigns when it comes to tracking them down. Technology providers are facing increasingly complex and stealthy attacks on popular communication tools, which is why the episode emphasizes the mounting challenges they face in defending them against such attacks. 

Recently, a critical flaw has been discovered in WhatsApp which has been catalogued as CVE-2025-55177, which has once again brought to the fore the security landscape around widely used communication platforms. Based on initial CVSS scores of 5.4 and 8.0, the vulnerability highlights how zero-day exploits continue to pose a challenge to users and device integrity, as well as undermine privacy and device integrity. 

It is believed that the root of the flaw is due to incomplete authorization in the handling of synchronization messages between linked devices. This weakness was the basis of the attack, which could be exploited as a tool to override the expected security features. Using this vulnerability, a malicious actor who has no legitimate association with the target could force a victim's device to process content from an arbitrary URL on its own behalf if exploited. 

The manipulation of trusted communication channels could serve as an entry point for remote code execution, or unauthorized delivery of malicious content, directly from the attacker's infrastructure, which can then be used to deliver malicious content. In such a scenario, users' trust is not only compromised, but it also highlights how vulnerable application-level security measures can be if authorization mechanisms are not properly enforced. 

There is an added level of seriousness to this discovery, since the exploit appears to have been a zero-click attack. In contrast to conventional attacks that require the user to open a file or click on a link, zero-click exploits do not require the user to interact with them whatsoever, which significantly reduces the chances of detection. 

As a result of silent compromises, attackers are able to install spyware or malicious code swiftly, discreetly, and with little or no trace until the damage has been done. WhatsApp's internal security team believes that the CVE-2025-55177 vulnerability was not an isolated occurrence. Rather than being isolated from the other vulnerability within Apple's ecosystem, it is thought to have been chained together with a separate vulnerability within the Apple ecosystem – CVE-2025-43300 – to allow sophisticated, targeted attacks.

In the Apple case, a CVSS score of 8.8 was assigned to the ImageIO framework that was characterized by an out-of-bounds write condition. When these vulnerabilities occur during the processing of images, they can corrupt memory, giving way to deeper system-level vulnerabilities. An exploit chaining strategy, whereby an application-level bug is paired up with an operating system vulnerability in order to maximize the scope and stealth of a campaign, is an increasingly popular strategy among advanced adversaries as a means of maximizing the scope and stealth of their operations. 

On August 20, Apple updated its entire product line in order to address CVE-2025-43300, issuing patches for iOS 18.6.2, iPadOS 18.6.2, and 17.7.10, Mac OS Sequoia 15.6.1, Mac OS Sonoma 14.7.2, and Mac OS Ventura 13.7.1. It was noted in the advisory that while the company had refrained from providing detailed technical details, they had been aware of reports that the flaw had already been exploited against specific individuals by users in the wild.

In line with the tactics used by state-sponsored groups and well-funded spyware vendors, these attacks were highly targeted and not indiscriminate, as they suggest that these attacks were highly targeted and not indiscriminate. In addition to mitigating the threat quickly, WhatsApp has also quickly rolled out patches that fix CVE-2025-55177 on all its platforms, rolling it out in late July and early August 2025. As with Apple, WhatsApp's version of iOS 2.2.21.73, WhatsApp Business, and WhatsApp for Mac all came with the patches. 

However, as Apple did, WhatsApp did not provide details of the observed attacks, and provided limited commentary on the nature or scale of the exploitation. The reticence that occurs when a zero-day exploitation is being actively exploited is not unusual, as revealing too much could help threat actors improve their techniques inadvertently. 

While the extent of the campaign is still unknown, the operational sophistication implied by these exploits suggests that an adversary with adequate resources has been engaged in this operation. This is because of the fact that zero-click vectors are being used as well as the seamless chaining of vulnerabilities across both application and operating system layers, which illustrates how complex cyber threats are becoming. 

In the broader context of these incidents, it is important to recognize that attackers are increasingly using multi-layered exploit chains to get around user defenses, get past traditional detection methods, and implant spyware in a highly precise manner. Taking a broader perspective of the WhatsApp and Apple vulnerabilities, it is important to note that today's interconnected digital environment creates a precarious balance between convenience and security. 

With the rapid expansion of messaging platforms, the attack surface is inevitably bound to increase, allowing adversaries to find weaknesses more easily. According to recent disclosures, it is imperative that timely patches, rigorous vulnerability management, and ongoing collaboration between vendors be implemented so that coordinated, high-level exploitation campaigns are limited in impact. 

In order to defend against zero-click exploit campaigns that leverage zero-click exploits, security specialists advise that a routine patch application does not suffice. There is a growing need for organizations to adopt a layered defense strategy that integrates technical safeguards with operational discipline in order to reduce exposure. 

Among the steps to take is updating WhatsApp and other messaging platforms to the most recent patched versions, enforcing mobile device management (MDM) baselines, and implementing solutions for detection and response of mobile endpoints (EDR) that can be used to detect as well as analyse the data. To further enhance resilience, system logs can be monitored for unusual activity, command-and-control traffic can be blocked at the network level, and threat intelligence data can be utilized. 

To eliminate possible persistence mechanisms, factory resets should be recommended when a compromise is suspected. Likewise, it is crucial to build user awareness by providing training on spyware risks and incident reporting, in addition to reviewing incident response playbooks to ensure they address zero-day and zero-click exploitation scenarios. In addition to these practices, organizations should adopt strict communication security policies, and conduct regular third-party risk assessments in order to strengthen their defense against stealthy spyware operations and reduce the impact of sophisticated intrusion attempts on their systems. 

There has been a sharp reminder resulting from the revelations surrounding WhatsApp and Apple vulnerabilities that no platform, no matter how popular or secure it appears to be, is immune to exploitation. In this day and age, zero-click spyware is becoming increasingly sophisticated, which underscores the necessity to treat mobile device security as a strategic priority rather than something people take for granted. 

The best way to do this for individuals would be to develop the habit of downloading and installing software updates as soon as they become available, to exercise caution when unusual behavior occurs on their mobile devices, and to consider the use of trusted mobile security tools. 

Organizations need to shift from compliance checklists and develop a culture of proactive resilience rather than relying on compliance checklists. This means investing in multiple defenses, continuous monitoring, and cross-team collaboration between the IT, security, and legal departments in order to better detect and contain incidents.

It is imperative that technology vendors, independent researchers, and civil society organisations collaboratively work together in order to hold spyware operators accountable for their actions and ensure that users retain trust in their digital communications in the future. 

In spite of vulnerabilities continuing to be found in the digital ecosystem, a combination of rapid response, transparency, and a security-first mindset can turn such incidents into opportunities for stronger defenses and more resilient digital ecosystems by eliminating vulnerabilities as quickly as possible.

Microsoft Flaw Blamed as Hackers Breach Canada’s House of Commons

 


In a recent security incident involving Canada's parliamentary network, hackers exploited a recently released Microsoft vulnerability to breach the House of Commons network, shaking up the country's parliament. 

According to an internal e-mail obtained by CBC News, the intrusion occurred on Friday and affected a database that was used to manage computers and mobile devices. The data revealed in the email included names, titles, email addresses, and details about computers and mobile devices, including operating systems, model numbers, and telephone numbers. 

Officials have not been able to link the attack with any nation-state or criminal group, but questions remain as to whether additional sensitive information has been accessed. According to a statement from Olivier Duhaime, spokesperson for the Speaker's Office, the House of Commons is cooperating closely with its national security partners to conduct an investigation. However, he declined to provide further information due to security concerns. 

An unauthorised actor gained access to the House's systems, which was first reported by CBC News on Monday, leading to the public discovery of the breach. According to an internal email of the intruders, they exploited a recent Microsoft vulnerability in order to gain access to parliamentary computers and mobile devices. 

There was a lot of information exposed, including employee names, job titles, office locations, e-mail addresses, as well as technical information about devices controlled by the House. A cybersecurity agency such as Canada's Communications Security Establishment (CSE) has joined the investigation, although no one knows who the attackers are. 

According to the CSE, a threat actor is defined as any entity seeking to disrupt or access a network without authorisation. In a recent report, the agency warned that foreign nations like China, Russia, and Iran are increasingly targeting Canadian institutions, despite this fact. Nevertheless, no attribution has been established in this case, and officials have cautioned against using the compromised information for scams, impersonation, or further invasions. 

According to Canada's latest Cyber Threat Assessment, the country faces an ever-increasing exposure to digital threats, and it is described as a "valuable target" for both state-sponsored adversaries and criminals who are financially motivated to do so. In the last two years, the Canadian Centre for Cyber Security has reported a significant increase in the number and severity of cyber-attacks, with a warning that state actors are increasingly aggressive. 

It has also been noted that cybercriminals are increasingly using illicit business models and artificial intelligence to expand their capabilities, according to Rajiv Gupta, head of the centre. Chinese cyber threats pose the greatest threat to Canada, according to the report, and it indicates that at least 20 government networks were compromised by threat actors affiliated with the People's Republic of China over the past four years.

The House of Commons incident is likely to be linked to a recently exploited zero-day Microsoft SharePoint vulnerability, which is known as CVE-2025-53770, although officials have not confirmed which particular flaw was exploited. During the exploitation of untrusted data in on-premises SharePoint Server, a vulnerability that has a CVSS score of 9 was discovered, which could allow an attacker to remotely execute code. 

The vulnerability has been reported by Viettel Cyber Security through Trend Micro’s Zero Day Initiative since July. Since then, the vulnerability has been actively exploited, which prompted Microsoft to issue a warning and recommend immediate measures to mitigate the problem while a full patch is being prepared. As a result of the breach of parliament, members and staff have been urged to stay vigilant against potential scams. 

The incident occurs at a time when Canada is facing an escalation of cyber threats that are becoming increasingly sophisticated as both adversaries and financially motivated criminals are increasingly leveraging advanced tools and artificial intelligence in order to gain an edge over their adversaries. During the past four years, the federal government has confirmed at least 20 network compromises linked to Beijing, indicating that China is the most sophisticated and active threat actor. 

There is an increasing pressure on Canada's critical infrastructure due to recent incidents like the hack on WestJet in June that disrupted both the airline's internal systems as well as its mobile application. Initially discovered in May, this vulnerability, which was confirmed to be actively exploited in late July, can allow the attacker to execute code remotely, allowing them to gain access to all SharePoint content, including sensitive configurations and internal file systems. 

As Costis pointed out, many major organisations, including Google and the United States, have recently been breached as a result of vulnerabilities in Microsoft platforms like Exchange and SharePoint. Several ransomware groups, including Salt Typhoon and Warlock, have been reported to have exploited these vulnerabilities by targeting nearly 400 organisations worldwide as a result of these campaigns.

In addition, the United States Cybersecurity and Infrastructure Security Agency (CISA) has also warned about the vulnerability, known as the “ToolShell” vulnerability. It was warned earlier this month that the vulnerability could enable not only unauthenticated access to systems, but also authenticated access to them through the use of network spoofing. This type of exploit could allow attackers to take complete control of SharePoint environments, including file systems and internal configurations. 

A Mandiant CEO, Charles Carmakal, emphasised on LinkedIn that it is not just about applying Microsoft's security patch, but about taking steps to mitigate this risk along with implementing Mitigation strategies, in addition to applying Microsoft's security patch. It was reported by Microsoft in a July blog post that nation-state actors based in China have been actively trying to exploit the vulnerability, including Linen Typhoon, Violet Typhoon, and possibly Storm-2603, among others. 

The group has historically targeted the intellectual property of governments, the defence sector, the human rights industry, strategic planning, higher education, as well as the media, finance, and health sectors throughout North America, Europe, and Asia. It has been reported that Linen Typhoon is known for its "drive-by compromises" that exploit existing vulnerabilities, whereas Violet Typhoon constantly scans exposed web infrastructure to find weaknesses, according to Microsoft. 

The House of Commons breach echoes a growing trend of security concerns linked to enterprise technologies that have been widely deployed in the past few years. As a result, government and corporate systems have become increasingly fragile. Because Microsoft platforms are omnipresent, security analysts argue that they provide adversaries with a high-value entry point that can have far-reaching consequences when exploited by adversaries. 

The incident highlights how, not only is it difficult to safeguard sensitive parliamentary data, but also to deal with systemic risks that cross critical sectors such as aviation, healthcare, finance, and higher education when they are exploited. There is an argument to be made that in order to achieve this goal, it will require not only timely patches and mitigations, but a cultural shift as well—one that integrates intelligence sharing, proactive threat hunting, and ongoing investments in cyber defence—along with the ongoing use of cyber defence technologies. 

Even though global threat actors are growing in strength and opportunity, the incident serves as a reminder that it is vital that national institutions are protected with vigilance that matches the sophistication and scale of their adversaries.

XE Group Rebrands Its Cybercrime Strategy by Targeting Supply Chains

 


Over the past decade, there has been a rise in the number of cyber threats targeting the country, including the XE Group, a hacker collective with Vietnamese connections. According to recent investigations, the group was responsible for exploiting two zero-day vulnerabilities in VeraCore's warehouse management platform, CVE-2025-25181 and CVE-2025-57968 known to be zero-day vulnerabilities. 

A suite of reverse shells and web shells that exploit these vulnerabilities were deployed by the adversaries, allowing them to gain remote access to targeted systems in covert ways. This development is an indication of the group's sophisticated cyber-attack techniques. Identified as CVE-2024-57968, the vulnerability is a critical upload validation vulnerability with a CVSS score of 9.9, affecting versions before 2024.4.2.1, and can allow adversaries to upload files into non-intended directories, which could result in unauthorized access to the files. 

Adventure VeraCore up to version 2025.1.0 is vulnerable to SQL injection flaw CVE-2025-25181, which could be exploited remotely to execute arbitrary SQL commands through the remote execution of SQL commands. In addition to the XE Group's past association with credit card fraud, their focus has now switched to targeted data theft, particularly within manufacturing and distribution organizations. 

Several recent attacks have been perpetrated by threat actors who exploited VeraCore security issues to install Web Shells, which allowed them to execute various malicious activities and remain persistent within compromised environments while they executed their malicious activities. The group's continued sophistication and adaptability in the cyber threat landscape is reflected in this recent report, which details a compromise of a Microsoft Internet Information Services (IIS) server where VeraCore's warehouse management system software is hosted, and it indicates the company's growing sophistication. 

Upon further analysis of this incident, it was discovered that the initial breach occurred in January 2020 as a result of a zero-day vulnerability in SQL injection. It is speculated that As a result of this exploitation, The XE Group deployed customized web shells, which researchers have described as very versatile tools that are designed to maintain persistent access inside victim environments as well as run SQL queries regarding those environments.

As an example, in the case of the compromised IIS server, the attackers reactivated a web shell that was planted four years earlier, showing that they have retained a foothold in the infrastructure targeted by them for many years. Security vendors have been warning that the XE Group is actively targeting supply chains in the manufacturing and distribution sectors. Though the group has historically been associated with extensive credit card skimming operations, it has recently gained a reputation for exploiting zero-day vulnerabilities to do more damage. 

According to researchers, the group's continued ability to adapt and increase sophistication underscores the group's ability to remain agile and sophisticated over the years. The reactivation of an older web shell indicates the group's strategic focus on achieving long-term operational objectives by maintaining long-term access to compromised systems. 

To enhance the threat investigation process, the rules have been designed to be compatible with several SIEM (Security Information and Event Management) systems, Endpoint Detection and Response systems (EDR), and Data Lake solutions aligned with the MITRE ATT&CK framework. There is a variety of metadata that is accessible in each rule, including references to cyber threat intelligence, attack timelines, triage recommendations, and audit configurations, guaranteeing that security analysis has a structured approach. 

Additionally, SOC Prime's Uncoder AI (Artificial Intelligence) capabilities enable the quick development of custom IOC-based queries that will be seamlessly integrated with SIEM and EDR platforms, thus eliminating the need for security professionals to manually search for indicators of compromise (IOCs). Intezer's analysis of XE Group activity and SOC Prime's Uncoder AI were used to achieve this.

As an alternative to the corporate-only service offered previously by Uncoder AI, customers can now benefit from Uncoder AI's full suite of capabilities, which enhances accessibility for independent risk analysis performed by individual researchers. As a consequence of the XE Group's adoption of zero-day exploits as part of their attack strategy, it became increasingly clear that adversarial techniques are becoming more sophisticated and adaptable, making it necessary to enter into proactive defence measures as soon as possible.

SOC Prime Platform is a scalable tool designed to assist organizations in enhancing their security posture, countering evolving threats effectively, and mitigating risks associated with adding more attack surfaces in an increasingly complex cyber landscape by utilizing the tools provided by the platform. The XE Group has exploited two zero-day VeraCore vulnerabilities, CVE-2025-25181 and CVE-2025-50308, in recent attacks in an attempt to deploy one or more web shells on compromised systems. 

These two vulnerabilities are critical upload validation flaws (CVSS 9.9) and SQL injection flaws (CVSS 5.7), respectively. In a report published jointly by Solis and Intezer, the researchers reported that the group exploited one of these vulnerabilities as early as January 2020 and maintained persistent access to the victim's environment for several years afterwards. There was an attempt in 2024 by some threat actors to reactivate a previously deployed web shell, demonstrating their ability to avoid detection while maintaining long-term access to compromised systems as they remain undetected. 

XE Group's evolving tactics come as part of a broader trend that threats are exploring the software supply chain as a way to achieve their goals. Some notable precedents include the SolarWinds attack, breaches into Progress Software's MOVEit file transfer product, an Okta intrusion that affected all customers, and an Accellion breach that enabled ransomware to be deployed on an organization's network.
