A new social engineering and malware campaign targets Android users, stealing card details to make payments or withdraw cash. Group-IB discovered the campaign, calling it WindRelay, and found that several successful attacks were carried out on European victims within the space of a 13-minute phone call. The attack relies on a skilled social engineer walking the victim through the process and two malware strains: An NFC relay malware called WindRelay, first discovered in August 2025, and SpyNote, a remote access trojan (RAT) that was leaked on cybercrime forums as far back as 2016. It goes like this: The attacker calls the target while posing as a helpdesk employee at their bank, convincing the victim-in-waiting that there is a problem with their payment card. While still on the phone, the attacker gets the target to install a version of SpyNote on their Android device. The file name includes the target's name, which the researchers said could suggest that each target is singled out specifically, and a degree of reconnaissance has to be carried out prior to the attack. Once installed, the attacker quickly uses the RAT's remote access to quietly install WindRelay on the attacker's device without their knowledge or input, all while the call was ongoing. The attacker then instructs the target to tap their payment card on their NFC-enabled smartphone and, when prompted, enter their PIN. WindRelay then captures the data from that interaction between the card's chip and the reader, similarly to how genuine point-of-sale machines authorize contactless payments. This is known as a live EMV APDU exchange. In order to fraudulently make payments using this data – without physical access to the payment card or the cardholder – the attacker must have a second device capable of using this data to authorize a payment. This could be a second Android smartphone capable of loading this data and transmitting it to an attacker-controlled POS terminal, which is linked to a fraudulent merchant bank account, or an ATM. The attacker then uses the captured live exchange data to execute fraudulent charges on the victim's card, authorized using the PIN they entered during the call. Group-IB said in its write-up: "In effect, the victim's card and the real terminal are still talking directly to each other – the fraudster's setup is just an invisible relay in between, passing the exchange back and forth across a distance. "Because the terminal is genuinely completing a live handshake with a real card, the transaction goes through and processes the withdrawal or purchase as normal." Doubling down on their access, Group-IB also noted that the attackers in one instance used their RAT access to access the victim's banking app and take out loans in their name. The researchers also said they observed 23 WindRelay-related samples uploaded to VirusTotal between November 2025 and July 2026, with signs pointing toward targeting victims in Czechia, Slovakia, and Slovenia. They were not able to pin down the attacker(s) behind the malware, although they said it was independently developed and the samples they saw uploaded to VirusTotal all contained unique UI elements, such as the victim's name, just like with the RAT. "This suggests the threat actor behind these campaigns most likely has the capability to dynamically build malicious applications tailored to individual victims," said Group-IB. "This case shows that modern fraud rarely relies on one technique," it added. "Here, the fraudster combined three capabilities in a single session – a live social engineering call, a personalized RAT for remote device control, and an NFC relay malware for physical cash-out. "The fraudster also used these capabilities to hit two separate payout channels – a digital loan and card-present purchases – before the bank or victim could react." The attack is similar to previous NFC relay-related campaigns, such as NGate in 2024 (and more recently in 2026), and Ghost Tap, the techniques involved in which closely align with WindRelay. Ghost Tap, also discovered in 2024, relies on a Chinese malware sold throughout the country's cybercrime Telegram communities, and according to Group-IB, it was responsible for losses exceeding $355,000 between November 2024 and August 2025 alone. ®
Enterprises must "feed" their AI ventures with reliable, well-curated data if they want worthwhile returns. But new mandates governing AI deployments also require them to act as careful custodians of their data, along with the infrastructure, supply chain, software and other aspects of their IT landscape. Sovereign AI gives an enterprise, or even a nation state, complete control over how its AI systems are built, deployed, operated, and governed. It emphasizes control over data, infrastructure, models, operations, and policies, often within specific legal, regulatory, or geographic boundaries. Sovereign AI matters for organizations and governments that need AI environments aligned with their own security, compliance, privacy, and governance requirements. For some, that means keeping sensitive data in-country. For others, it means controlling who can access systems, where workloads run, how models are governed, and which local laws apply. The HPE Sovereign AI Factory lets customers in highly-regulated industries keep sensitive data, models, and operations under strict local control, using customized, validated infrastructure integrated with HPE services from deployment to operational support that helps customers with security, compliance, and control across infrastructure, data, and AI models. In this Hot Seat, James Hayes hears from Thierry Pienaar, HPE fellow, Chief Technology Officer for HPC & AI worldwide at HPE, and Kaushik Shirhatti, VP, AI factory at NVIDIA, on how HPE and NVIDIA work together to help customers meet the latest sovereign AI mandates. Pienaar and Shirhatti sit on the frontline of this shift in AI development. In the video they cut through market hype and misunderstandings to identify the key considerations for any organization's sovereign AI program. You will learn: Why a sovereign AI strategy has become a priority so quickly, as governments and highly-regulated sectors seek greater control over their AI systems, data, and innovation plans. The key drivers for sovereign AI, and how it differs from at-scale standard AI workloads. How sovereign AI introduces new rigors of security, such as air-gapping and identity federation. How agentic AI plays into sovereign AI requirements, and how agents can be protected while retaining the freedom to deliver useful results. How HPE and NVIDIA partner to deliver sovereign AI factories that let customers build and run AI models while retaining complete control over sensitive data, infrastructure, and compliance boundaries within their defined borders.

Uber Freight says it is investigating a "data security incident" days after the Helix extortion group listed the company on its data leak site on August 6. Helix claims to have stolen nearly 1 million files from mailboxes, OneDrive accounts, the accounts receivable department, and other repositories. An Uber Freight spokesperson told The Register that the incident was under investigation but had not disrupted the company's daily operations. "We are investigating a data security incident involving unauthorized access to a portion of Uber Freight's systems and repositories. The incident was identified, contained, and remediated, and we promptly engaged federal law enforcement. "There has been no impact to Uber Freight's business operations, which continue in the normal course without disruption. Our systems are secure and fully operational." Uber Freight is the ubiquitous ride-sharing company's lesser-known logistics arm, which describes itself as "one of North America's largest managed transportation and multimodal capacity networks." Its website claims that it manages 18 million shipments carrying more than $17 billion worth of goods each year. The Register did not download the files Helix released in stages, and Uber Freight neither confirmed nor denied that the material was authentic. Helix is one of several recently established extortion brands linked by researchers to infrastructure associated with BlackFile, which retired its name in May. According to Google Threat Intelligence Group (GTIG), Helix shares infrastructure with the Pink, Redact, and Falcon brands. Google tracks the wider cluster of activity as UNC6671. Operators associated with UNC6671 often use vishing to gain an initial foothold, posing as IT helpdesk staff overseeing mandatory security migrations, Google said. They contact employees on their personal phones and use device code phishing to obtain credentials and authenticated sessions before siphoning data from cloud services such as Microsoft 365. They have also targeted Okta identity infrastructure. Researchers believe the UNC6671-linked brands have recently shifted toward organizations in higher-value sectors. Since June, they have favored technology, transportation, and hospitality targets after focusing on manufacturing, real estate, healthcare, and insurance during April and May. Why multiple brands emerged after BlackFile shut down is unclear. GTIG said the strategy could "compartmentalize operations, hide overall breach volumes, and isolate any negotiation fallout," although other plausible explanations exist. Internal disagreements over matters such as handling finances and operational security could have led to the fragmentation of UNC6671, GTIG speculated. The core members may also be looking to retain control over the intrusion and data theft aspects of the attack, while outsourcing negotiations and extortion. The different groups may also just be using the same commoditized phishing tools. ®
The UK's criminal records office, ACRO, has escaped a fine and received a regulatory reprimand after security failings potentially exposed highly sensitive data belonging to nearly 11,000 people. ACRO disclosed the "cybersecurity incident" in April 2023, and said at the time that it had no evidence to suggest that any data was compromised. However, it has now emerged that attackers maintained persistent access to ACRO's website and content management system for more than seven months, and staged sensitive data for possible exfiltration. According to the Information Commissioner's Office (ICO), which reprimanded ACRO rather than imposing a financial penalty, the breach was uncovered in March 2023 only because ACRO was investigating a separate intrusion. The watchdog said that while investigating an SQL injection attack that compromised 15 sets of credentials, most belonging to ACRO staff, investigators found evidence of separate intrusions dating back to July 8, 2021. The incidents fell into three categories, the ICO said. Some did not affect personal data, while others exposed only a small number of account credentials. The most serious involved ACRO's website and its Kentico content management system. The intrusion began on August 5, 2022, and the attackers maintained persistent access, without being detected, until March 14, 2023. The ICO found that ACRO ran version 12.0.0 of Kentico CMS from September 2019 until March 2023 without applying the patches and hotfixes released during that period, leaving known vulnerabilities unresolved. The ICO blamed poor communication between ACRO and its managed service provider. The supplier did not learn that patching was its responsibility until February 2020 and continued to assume that it was not required to monitor actively for security updates. "The ambiguity around who was accountable for identifying necessary Kentico CMS patches created a gap where patches and hotfixes were missed, which ultimately left ACRO's website vulnerable," the ICO said. Further, ACRO did not have a documented policy that covered patching Kentico CMS, nor could it demonstrate how vulnerabilities were identified or prioritized. ACRO's Trend Micro antivirus generated alerts, but nobody appears to have been minding them. The records office told the ICO that, for reasons redacted from the postmortem, it was "unable to establish what business processes existed for the assessment or handling of security alerts at the relevant time." It also could not identify which roles were responsible for reviewing these alerts at the time, ultimately resulting in them going unread. ACRO's poor logging means that, despite an extensive investigation by a third-party cybersecurity outfit, it remains impossible to determine whether the affected data was exfiltrated. Investigators did establish that the attackers staged the data for possible exfiltration between February 15 and 16, 2023. The potentially exposed material included: Police Certificate Applications Subject Access Request (SAR) forms and International Child Protection Certificate forms Names Dates of birth Addresses National Insurance numbers Passport and driving licence details Bank account information Biometric data Highly sensitive criminal offence and special category information ACRO notified 84,048 people of the breach, although investigators later determined that data relating to no more than 10,920 individuals had potentially been staged for exfiltration. Of these, ACRO received 35 formal complaints citing personal distress and concern about the risk of identity theft and financial loss, according to the ICO's reprimand document [PDF]. "Complainants included those connected to Police Certificates, International Child Protection Certificates, and victims of domestic violence." The ICO also received six complaints citing similar concerns. ACRO's saving grace was its network segmentation, which prevented the attackers from straying beyond the CMS into other systems, the ICO noted. Since the attack was discovered, ACRO has made a number of improvements to its security, including decommissioning the compromised infrastructure (although not until June 2023), implementing a SIEM, improving visibility, monitoring, and network segmentation, hardening systems, and migrating to Salesforce Experience Cloud. Jonathan Balmforth, group manager of civil and cyber investigations at the ICO, said: "This case highlights how basic cyber security failings can create significant risks for thousands of people, particularly where organizations process large volumes of highly sensitive personal information. "Organizations must ensure there is clear accountability for identifying, assessing and applying security updates. They must also have effective monitoring in place so that warning signs of cyberattacks are identified, investigated and acted upon promptly. "The lessons from this incident are clear. Having the right policies, responsibilities and oversight arrangements in place is just as important as having the right technology. "We welcome the improvements ACRO has made since these incidents. We hope other organizations will use this case as an opportunity to review their own processes and responses to ensure personal information remains properly protected." ACRO welcomed the reprimand from the ICO and highlighted the steps it has taken since to bolster its security. A spokesperson told The Register: "Since the cybersecurity incident was identified in March 2023, we have worked hard to strengthen our systems and safeguards. "In particular, we immediately took the previous website offline and subsequently decommissioned it. We also took steps to protect customers, including making sure anyone potentially affected was informed at the earliest possible stage." They went on to say: "We accept the ICO's findings of the infringements. We are grateful for the recognition from the Information Commissioner of the multiple remedial steps ACRO has taken in light of this incident and are committed to maintaining high standards of data protection and information security in future." ®
An Akira ransomware affiliate rebooted a victim’s computer into Safe Mode to kill its security tools – and in the process sabotaged their own malware when the limited-function startup mode also broke their encryptor. “Akira's encryptor is engineered for speed, relying on concurrent worker threads and heavy memory mapping rather than simple sequential read-and-write operations. That high-performance design is likely what caused it to break in Safe Mode,” Huntress security operations analyst James Northey told The Register. “Safe Mode loads a minimal driver set, which can restrict storage controllers and pagefile availability,” he added. “A heavy, multi-threaded encryptor strains that constrained environment far more than the lighter, streamed-I/O designs used by other ransomware families.” But the ending wasn't entirely happy for the victim. The attacker had already stolen credentials and data from file shares before Safe Mode prevented the ransomware from doing its job. Northey detailed the incident in a Wednesday blog and cautioned that this was more likely a memory-configuration issue, and shouldn't be taken as a practical defense to prevent Akira ransomware from locking up valuable files. “Ultimately this could be a case of winning the battle, but not the war,” Northey wrote. “It’s possible that a host with more physical memory or a larger page file might give akira.exe enough virtual memory to encrypt the endpoint in Safe Mode,” Northey added. “Akira’s developers or affiliates could retool the encryptor to reduce its memory demands or make its Safe Mode launch sequence more reliable, meaning that the same failure may not occur in a future intrusion.” Nonetheless, there's one big lesson here: For the love of all that is holy, turn on multi-factor authentication (MFA). Here’s a closer look at what happened, and how to prevent it from happening to you. How it started… In early August, Huntress responded to an incident that began, as most Akira intrusions do, with a SonicWall SSL VPN. On August 4, the VPN logged a credential-spray attack: a burst of failed logins using bad credentials that it denied. But then, seven minutes later, one of them succeeded when the attacker used a valid VPN account that wasn’t protected by MFA. Once they had gained access, the criminal accessed the domain controller via Remote Desktop Protocol (RDP) and queried Active Directory to hoover up detailed information about the network, users, groups, computers – essentially everything an attacker needs to know about who and what to target for lateral movement and mass encryption in a ransomware attack. “The enumeration was a full-property dump of every user and every computer in the domain,” Northey wrote. The Akira ransomware affiliate then moved to the application server to start collecting stolen data, downloading WinRAR and using that tool to archive mapped file shares before sending the stolen data to cloud storage using s5cmd, a fast S3 transfer utility. They also installed remote desktop software AnyDesk, configured to start with Windows, and abused this legitimate tool as a remote-access trojan, giving the attacker hands-on keyboard control. They also used it as a command-and-control channel to drop more malware, including the very cleverly named akira.exe ransomware binary – because no one would guess what that executable could be, right? Then came the Safe Mode reboot Here’s where things went sideways for the ransomware scumbag. About three hours into the intrusion, the attacker forced the computer to reboot into Safe Mode with Networking, a boot mode that only loads essential drivers and services, blocking most third-party software. Attackers, especially ransomware gangs, do this to disable endpoint detection and response products and other security tools that would otherwise detect and stop their malware from infecting victims’ machines. While some ransomware crews, including Snatch and AvosLocker, have abused Safe Mode for this purpose for years, Huntress has never seen Akira do it until now. In this case, the reboot stopped the Huntress agent and disabled Microsoft Defender's real-time protection, preventing Defender from quarantining the malicious file. “The attacker got their blind window,” Northey wrote. “What they didn't get was a clean detonation.” Thirteen seconds after the reboot, the computer started spewing memory errors. Safe Mode boots with constrained virtual memory, and it didn’t have sufficient memory to encrypt the endpoint. Essentially, Safe Mode not only acted as an EDR killer, but also borked the ransomware. In addition to the obvious recommendations – like make sure you receive alerts on bursts of failed VPN logins against multiple usernames from one source, and require MFA on every VPN account – Huntress suggests organizations keep an eye out for this Safe Mode play. Specifically, “alert on boot-configuration changes and Safe Mode boots: msconfig.exe / bcdedit activity, Kernel-Boot EID 27 with a SAFEBOOT load option, Kernel-General EID 12 BootMode=2, and third-party security services stopping (System EID 7036),” Northey wrote. Also, “watch for tooling being added to the Safe Mode minimal-service registry list.” ®
