UK Army Probes Leak of Special Forces Identities in Grenadier Guards Publication

 

The British Army has initiated an urgent investigation following the public exposure of sensitive information identifying members of the UK Special Forces. General Sir Roly Walker, Chief of the General Staff, has directed a comprehensive review into how classified data was shared, after it was found that a regimental newsletter had published names and postings of elite soldiers over a period of more than ten years. 

The internal publication, created by the Grenadier Guards Regimental Association, is believed to have revealed the identities and current assignments of high-ranking officers serving in confidential roles. Several names were reportedly accompanied by the abbreviation “MAB,” a known military code linked to Special Forces. Security experts have expressed concern that such identifiers could be easily deciphered by hostile actors, significantly raising the risk to those individuals. 

The revelation has triggered backlash within the Ministry of Defence, with Defence Secretary John Healey reportedly outraged by the breach. The Ministry had already issued warnings about this very issue, yet the publication remained online until it was finally edited last week. The breach adds to growing concern over operational security lapses in elite British military units.  

This latest disclosure follows closely on the heels of another incident in which the identities of Special Forces soldiers involved in missions in Afghanistan were exposed through a separate data leak. That earlier breach had been shielded by a legal order for nearly two years, emphasizing the persistent nature of such security vulnerabilities. 

The protection of Special Forces members’ identities is a critical requirement due to the covert and high-risk nature of their work. Publicly exposing their names can not only endanger lives but also jeopardize ongoing intelligence missions and international collaborations. The leaked material is also said to have included information about officers working within the Cabinet Office’s National Security Secretariat—an agency that advises the Prime Minister on national defence—and even a soldier assigned to General Walker’s own operational staff. 

While the Grenadier Guards’ publication has now removed the sensitive content, another regiment had briefly published similar details before promptly deleting them. Still, the extended availability of the Grenadier data has raised questions about oversight and accountability in how military associations manage sensitive information.  

General Walker, a former commander of the Grenadier Guards, announced that he has mandated an immediate review of all information-sharing practices between the army and regimental associations. His directive aims to ensure that stronger protocols are in place to prevent such incidents in the future, while still supporting the positive role these associations play for veterans and serving members alike. 

The Defence Ministry has not released details on whether those named in the leak will be relocated or reassigned. However, security analysts say the long-term consequences of the breach could be serious, including potential threats to the personnel involved and operational risks to future Special Forces missions. As investigations continue, the British Army is now under pressure to tighten internal controls and better protect its most confidential information from digital exposure.

Jammu Municipal Corporation Targeted in Major Cyberattack, Sensitive Data Allegedly Stolen

 

In a significant breach of digital infrastructure, the Jammu Municipal Corporation (JMC) has fallen victim to a cyberattack believed to have resulted in the loss of vast amounts of sensitive data. According to high-level intelligence sources, the attackers managed to compromise the website, gaining access to critical records and databases that may include personally identifiable information such as Aadhaar numbers, property ownership documents, tax filings, infrastructure blueprints, and internal administrative communications.  

The breach, which occurred on Friday, has prompted an immediate investigation and system lockdown as cybersecurity teams race to contain the damage and begin recovery operations. Officials involved in the incident response have confirmed that website functionality has been suspended as data restoration processes are initiated. Top intelligence sources indicate that the attack bears hallmarks of Pakistan-sponsored cyber operations aimed at undermining India’s administrative framework. “These tactics are consistent with state-backed cyber warfare efforts targeting strategic and sensitive zones like Jammu and Kashmir,” said a senior intelligence official.

“The objective is often to destabilize public services and spread fear among the populace.” The JMC’s website is a key platform used to manage municipal services, property taxes, and local development projects. Its compromise has raised concerns about the broader implications for civic governance and the potential misuse of the stolen data.  

This latest breach follows a series of unsuccessful but alarming hacking attempts by groups linked to Pakistan. Just a day before the JMC attack, hacker collectives such as ‘Cyber Group HOAX1337’ and ‘National Cyber Crew’ reportedly targeted several Indian websites. Cybersecurity teams were able to detect and neutralize these threats before they could cause any major disruption. Among the recent targets were the websites of Army Public School Nagrota and Army Public School Sunjuwan. These were reportedly subjected to defacement attempts featuring inflammatory messages referencing the victims of the Pahalgam terror attack. 

In another incident, a portal catering to the healthcare needs of retired armed forces personnel was compromised and vandalized. Cybersecurity experts warn that such attacks often aim to disrupt not only public trust but also national morale. The recurring pattern of targeting vulnerable groups—such as schoolchildren and elderly veterans—further emphasizes the psychological warfare tactics employed by these groups. 

As recovery efforts continue, the Indian government is likely to review its cybersecurity protocols across public sector systems, especially in high-risk regions. Enhanced defense measures and greater inter-agency coordination are expected to follow. The investigation remains ongoing, and further updates are expected in the coming days.

SK Telecom Malware Attack Exposes USIM Data in South Korea

 

SK Telecom, South Korea’s top mobile carrier, has disclosed a security incident involving a malware infection that exposed sensitive information tied to users’ Universal Subscriber Identity Modules (USIMs). The breach was detected on the night of April 19, 2025, during the weekend when many companies operate with reduced cybersecurity staffing. 

With nearly half of South Korea’s mobile market share and around 34 million subscribers, SK Telecom holds a crucial position in the country’s telecommunications sector. In an official statement, the company explained that malware had infiltrated parts of its network, prompting immediate action to contain the threat. 

The affected systems were isolated swiftly, and the malicious software was removed. So far, SK Telecom has stated there is no confirmed misuse of customer data linked to this breach. This was reported to the Korea Internet & Security Agency (KISA) on April 20, and to the Personal Information Protection Commission. 
Investigations are ongoing to determine how the attackers gained access and the extent of the data exposed. USIM cards store essential data such as International Mobile Subscriber Identity (IMSI) numbers, phone numbers (MSISDN), encryption keys for network authentication, and sometimes even stored contacts or text messages. Unauthorized access to this information could enable cybercriminals to conduct targeted surveillance, track users’ locations, or perform SIM-swapping attacks that could compromise online accounts and digital assets. 

In response, SK Telecom has strengthened security around USIM card management, increasing checks on SIM card replacement activities and monitoring authentication processes for suspicious behavior. Accounts showing irregular activities could face automatic suspension to prevent potential fraud. Additionally, the carrier is advising customers to activate their USIM protection service, a preventive measure that restricts unauthorized SIM swaps, adding extra protection to user accounts. 

A hacking group is yet to claim responsibility for the breach. SK Telecom emphasized that while the malware was neutralized quickly, they remain vigilant and are working closely with cybersecurity authorities to uncover more details about the intrusion and enhance future protections. 

This breach highlights ongoing risks faced by large mobile operators, especially during periods when cyber defenses might be less robust. It also underscores the critical need for mobile carriers to adopt continuous security monitoring and proactive measures to protect customer data from emerging threats. 

As investigations continue, SK Telecom has committed to updating customers and regulators about any new findings or developments related to the incident.

How to Protect Your Smartphone During US Border Crossings

 

Crossing into the United States has become riskier since the start of Trump’s second administration. Foreign visitors and US visa holders are increasingly being detained, questioned, or deported. As uncertainty grows, travel demand from Canada and Europe has dropped sharply. Regardless of why you are traveling, US Customs and Border Protection (CBP) has the authority to search phones and other electronic devices at the border. 

While other countries also inspect devices, the volatile US policies have led travelers and companies to reconsider what they carry. Canada has issued travel warnings, and journalists are advised to prepare for device searches. At the border, CBP can demand PINs or biometrics to unlock devices. US citizens and green card holders can refuse without being denied entry, although this may trigger additional questioning or device seizure. Visa holders and visitors, however, face detention or deportation if they refuse a search. Travelers must assess their own risk based on legal status, nationality, profession, and online activity. 

To minimize risk, disable facial recognition or fingerprint unlock before traveling and use only a PIN. Update your phone’s software to make it harder to crack. Carry a paper boarding pass and keep your phone off or out of sight when approaching agents. One strategy is to travel with a separate device, either by wiping an old phone or buying a new one. Build a limited digital footprint on the travel phone—use separate emails, social media accounts, and encrypted messaging apps like Signal. 

However, the device should not appear suspiciously clean; normal usage should be simulated to avoid drawing attention. Another option is to clean your primary phone before traveling by backing up and deleting sensitive data and unnecessary apps. After returning, you can restore your phone from backup. However, mistakes in this process can leave traces of personal information vulnerable during inspection. Even if you don’t make major changes, basic steps like deleting old apps, updating software, limiting social media use, and keeping important documents printed can protect your privacy. 

Experts warn that travelers should assume border agents may scrutinize online presence and past posts. As device searches become more common at US borders, preparing ahead of travel has become critical for safeguarding personal information.

Change Healthcare Restores Clearinghouse Services After Nine-Month Recovery From Ransomware Attack

 

Change Healthcare has announced the restoration of its clearinghouse services, marking a significant milestone in its recovery from a debilitating ransomware attack by the ALPHV/Blackcat group in February. 

The attack caused unprecedented disruption to one of the U.S.’s most critical healthcare transaction systems, which processes over 15 billion transactions annually and supports payments and communications for hospitals, healthcare providers, and patients. The breach led to widespread financial and operational issues, with the American Hospital Association (AHA) reporting that 94% of U.S. hospitals relying on Change Healthcare were affected. Many hospitals experienced severe cash flow challenges, with nearly 60% reporting daily revenue losses of $1 million or more. These difficulties persisted for months as Change Healthcare scrambled to restore its services and mitigate the attack’s impact. 

In response to the financial strain on healthcare providers, UnitedHealth-owned Optum launched a Temporary Funding Assistance Program in March. This initiative provided over $6 billion in interest-free loans to healthcare providers to address cash flow shortages. As of October, $3.2 billion of the funds had been repaid, reflecting progress in stabilizing the industry. However, some services, such as Clinical Exchange, MedRX, and the Payer Print Communication System, are still undergoing restoration, leaving providers to navigate ongoing challenges. 

The breach also exposed sensitive information of approximately 100 million individuals, making it one of the most significant healthcare data breaches in history. Victims’ full names, email addresses, banking details, and medical claims records were among the data compromised. Change Healthcare’s parent company, UnitedHealth, confirmed that the attackers gained access through stolen credentials used to log into a Citrix portal that lacked multi-factor authentication (MFA). UnitedHealth CEO Andrew Witty testified before Congress, admitting to authorizing a $22 million ransom payment to the attackers. He described the decision as one of the hardest he had ever made, emphasizing the urgent need to minimize further harm to the healthcare system. 

Cybersecurity experts have criticized Change Healthcare for failing to implement basic security protocols, including MFA and robust network segmentation, prior to the attack. The attack’s aftermath has been costly, with remediation expenses exceeding $2 billion as of the most recent UnitedHealth earnings report. Critics have described the company’s lack of preventive measures as “egregious negligence.” Tom Kellermann, SVP of cyber strategy at Contrast Security, highlighted that the company failed to conduct adequate threat hunting or prepare for potential vulnerabilities, despite its critical role in the healthcare ecosystem. 

Beyond the immediate financial impact, the incident has raised broader concerns about the resilience of U.S. healthcare infrastructure to cyberattacks. Experts warn that the sector must adopt stronger cybersecurity measures, including advanced threat detection and incident response planning, to prevent similar disruptions in the future. The restoration of Change Healthcare’s clearinghouse services represents a major step forward, but it also serves as a reminder of the severe consequences of insufficient cybersecurity measures in an increasingly digital healthcare landscape. 

The attack has underscored the urgent need for organizations to prioritize data security, invest in robust safeguards, and build resilience against evolving cyber threats.

Cisco Fixes Critical CVE-2024-20418 Vulnerability in Industrial Wireless Access Points

These URWB access points are essential for maintaining robust wireless networks in environments like manufacturing plants, transportation systems, and other infrastructure-intensive industries. The vulnerability allows remote, unauthenticated attackers to perform command injection attacks with root privileges by exploiting the device’s web-based management interface. 

This vulnerability results from inadequate validation of input data within Cisco’s Unified Industrial Wireless Software, specifically affecting the web management interface of URWB access points. By sending specially crafted HTTP requests, attackers could exploit this flaw to execute arbitrary commands with root-level access, potentially leading to unauthorized control over the device. This level of access could compromise critical network infrastructure, posing serious risks to businesses relying on URWB technology for uninterrupted connectivity. The vulnerability specifically impacts Cisco Catalyst models IW9165D, IW9165E, and IW9167E when URWB mode is enabled. 

For users concerned about their device’s security, Cisco advises checking vulnerability status by using the “show mpls-config” command in the command-line interface (CLI). If the command confirms URWB mode is active, the device may be vulnerable to potential attacks. Cisco’s Product Security Incident Response Team (PSIRT) has stated that it is not aware of any instances of this vulnerability being actively exploited in real-world scenarios. However, given the nature of this vulnerability, Cisco urges users to update their devices promptly to mitigate the risk. Currently, Cisco has not issued workarounds for this issue. 

As a result, companies relying on these models are advised to stay alert for firmware updates or patches that Cisco may release to resolve the vulnerability. The lack of a temporary fix underlines the importance of applying any future updates immediately, especially as remote exploitation could have significant consequences for the affected systems. For organizations using these Cisco models, securing network access and strengthening device-level defenses can be critical in mitigating potential risks. Limiting access to the web-based management interface, monitoring device activity, and conducting frequent security audits are some proactive steps administrators can take.

Prometei Botnet: The Persistent Threat Targeting Global Systems

 

The Prometei botnet, active since at least 2016, continues to pose a persistent threat worldwide by exploiting unpatched software vulnerabilities. First identified in 2020, Prometei has since infected over 10,000 systems across diverse regions, including Brazil, Indonesia, Turkey, and Germany. Its resilience stems from its focus on widely used software gaps, particularly in systems with weak configurations, unmonitored security measures, or outdated patches. The Federal Office for Information Security in Germany has labeled it a medium-impact threat, given its extensive reach and ability to bypass security protocols. Prometei operates by exploiting vulnerabilities in widely used software, spreading particularly through unpatched or poorly configured Exchange servers. 

Critical Start’s Callie Guenther highlights Prometei’s strategy of leveraging regions with inadequate cybersecurity, making it highly effective in targeting various systems regardless of location. One notable aspect is its ability to spread through legacy vulnerabilities, such as the BlueKeep flaw in Remote Desktop Protocol (RDP), which has a critical CVSS score of 9.8. By targeting these known issues, Prometei can quickly access poorly maintained systems that remain unprotected. A Prometei attack often starts with a series of network login attempts, typically originating from locations associated with known botnet infrastructure. Once access is secured, the malware tests various system weaknesses, particularly outdated vulnerabilities like BlueKeep and EternalBlue. If successful, it can propagate through Server Message Block (SMB) systems or use ProxyLogon flaws to exploit Windows environments further. 

Prometei’s use of outdated exploits could be seen as less sophisticated; however, its approach is strategic, focusing on identifying vulnerable, under-maintained systems rather than tackling those with robust security protocols. Once established in a target system, Prometei employs several techniques to maintain control and evade detection. For example, it uses a domain generation algorithm (DGA) to enhance its command-and-control (C2) system, allowing continuous operation even if some domains are blocked. It further manipulates firewall settings to ensure its traffic is not obstructed, enabling it to persist even after system reboots. Among its advanced methods is the use of the WDigest protocol, which stores plaintext passwords in memory. 

Prometei forces systems to store passwords in plaintext, then exfiltrates them while bypassing detection by configuring Windows Defender to ignore specific files. The primary goal of Prometei appears to be cryptojacking, as it harnesses infected systems to mine the Monero cryptocurrency without the owners’ knowledge. Additionally, it installs an Apache web server as a web shell, creating a backdoor for attackers to upload more malicious files or execute commands. Prometei’s presence, according to Trend Micro’s Stephen Hilt, often signals deeper security concerns, as it can coexist with other malicious software, highlighting vulnerabilities that attackers may leverage for various purposes. Interestingly, Prometei avoids certain regions, specifically targeting systems outside former Soviet countries. Its command-and-control servers bypass exit nodes within these nations, avoiding accounts tagged as “Guest” or “Other user” in Russian.

Older versions of Prometei also included Russian-language settings, hinting at a potential connection to Russian-speaking developers. The botnet’s name, “Prometei,” references the Greek titan Prometheus, symbolizing a persistence that echoes the botnet’s own sustained presence in global cyber threats. Prometei exemplifies the persistent and evolving nature of modern botnets. Its success in exploiting well-known but unpatched vulnerabilities underscores the importance of maintaining updated security systems. For organizations worldwide, especially those with legacy systems or lax monitoring, Prometei serves as a critical reminder to reinforce defenses against cyber threats, as outdated security leaves systems vulnerable to malicious actors seeking to exploit any gap available.
