SonicWall Urges Password Resets After Cloud Backup Breach Affecting Under 5% of Customers

SonicWall Urges Password Resets After Cloud Backup Breach Affecting Under 5% of Customers

Sep 18, 2025 Data Breach / Network Security
SonicWall is urging customers to reset credentials after their firewall configuration backup files were exposed in a security breach impacting MySonicWall accounts. The company said it recently detected suspicious activity targeting the cloud backup service for firewalls, and that unknown threat actors accessed backup firewall preference files stored in the cloud for less than 5% of its customers. "While credentials within the files were encrypted, the files also included information that could make it easier for attackers to potentially exploit the related firewall," the company said . The network security company said it's not aware of any of these files being leaked online by the threat actors, adding it was not a ransomware event targeting its network. "Rather this was a series of brute-force attacks aimed at gaining access to the preference files stored in backup for potential further use by threat actors," it noted. It's currently not known who is...
CountLoader Broadens Russian Ransomware Operations With Multi-Version Malware Loader

CountLoader Broadens Russian Ransomware Operations With Multi-Version Malware Loader

Sep 18, 2025 Malware / Cybercrime
Cybersecurity researchers have discovered a new malware loader codenamed CountLoader that has been put to use by Russian ransomware gangs to deliver post-exploitation tools like Cobalt Strike and AdaptixC2 , and a remote access trojan known as PureHVNC RAT. "CountLoader is being used either as part of an Initial Access Broker's (IAB) toolset or by a ransomware affiliate with ties to the LockBit, Black Basta, and Qilin ransomware groups," Silent Push said in an analysis. Appearing in three different versions – .NET, PowerShell, and JavaScript – the emerging threat has been observed in a campaign targeting individuals in Ukraine using PDF-based phishing lures and impersonating the National Police of Ukraine. Silent Push told The Hacker News that it does not have any insight into the nature of malware that was dropped using CountLoader. It's worth noting that the PowerShell version of the malware was previously flagged by Kaspersky as being distributed using DeepSe...
SilentSync RAT Delivered via Two Malicious PyPI Packages Targeting Python Developers

SilentSync RAT Delivered via Two Malicious PyPI Packages Targeting Python Developers

Sep 18, 2025 Malware / Supply Chain Attack
Cybersecurity researchers have discovered two new malicious packages in the Python Package Index (PyPI) repository that are designed to deliver a remote access trojan called SilentSync on Windows systems. "SilentSync is capable of remote command execution, file exfiltration, and screen capturing," Zscaler ThreatLabz's Manisha Ramcharan Prajapati and Satyam Singh said . "SilentSync also extracts web browser data, including credentials, history, autofill data, and cookies from web browsers like Chrome, Brave, Edge, and Firefox." The packages, now no longer available for download from PyPI, are listed below. They were both uploaded by a user named "CondeTGAPIS." sisaws (201 Downloads) secmeasure (627 Downloads) Zscaler said the package sisaws mimics the behavior of the legitimate Python package sisa, which is associated with Argentina's national health information system, Sistema Integrado de Información Sanitaria Argentino (SISA). However, ...

How CISOs Can Drive Effective AI Governance

How CISOs Can Drive Effective AI Governance

Sep 18, 2025 Threat Intelligence / Enterprise AI
AI’s growing role in enterprise environments has heightened the urgency for Chief Information Security Officers (CISOs) to drive effective AI governance. When it comes to any emerging technology, governance is hard – but effective governance is even harder. The first instinct for most organizations is to respond with rigid policies. Write a policy document, circulate a set of restrictions, and hope the risk is contained. However, effective governance doesn’t work that way. It must be a living system that shapes how AI is used every day, guiding organizations through safe transformative change without slowing down the pace of innovation.  For CISOs, finding that balance between security and speed is critical in the age of AI. This technology simultaneously represents the greatest opportunity and greatest risk enterprises have faced since the dawn of the internet. Move too fast without guardrails, and sensitive data leaks into prompts, shadow AI proliferates, or regulatory gaps bec...
Google Patches Chrome Zero-Day CVE-2025-10585 as Active V8 Exploit Threatens Millions

Google Patches Chrome Zero-Day CVE-2025-10585 as Active V8 Exploit Threatens Millions

Sep 18, 2025 Vulnerability / Browser Security
Google on Wednesday released security updates for the Chrome web browser to address four vulnerabilities, including one that it said has been exploited in the wild. The zero-day vulnerability in question is CVE-2025-10585 , which has been described as a type confusion issue in the V8 JavaScript and WebAssembly engine. Type confusion vulnerabilities can have severe consequences as they can be weaponized by bad actors to trigger unexpected software behavior, resulting in the execution of arbitrary code and program crashes. Google's Threat Analysis Group (TAG) has been credited with discovering and reporting the flaw on September 16, 2025. As is typically the case, the company did not share any additional specifics about how the vulnerability is being abused in real-world attacks, by whom, or the scale of such efforts. This is done to prevent other threat actors from exploiting the issue before users can apply a fix. "Google is aware that an exploit for CVE-2025-10585 exis...
TA558 Uses AI-Generated Scripts to Deploy Venom RAT in Brazil Hotel Attacks

TA558 Uses AI-Generated Scripts to Deploy Venom RAT in Brazil Hotel Attacks

Sep 17, 2025 Malware / Artificial Intelligence
The threat actor known as TA558 has been attributed to a fresh set of attacks delivering various remote access trojans (RATs) like Venom RAT to breach hotels in Brazil and Spanish-speaking markets. Russian cybersecurity vendor Kaspersky is tracking the activity, observed in summer 2025, to a cluster it tracks as RevengeHotels. "The threat actors continue to employ phishing emails with invoice themes to deliver Venom RAT implants via JavaScript loaders and PowerShell downloaders," the company said . "A significant portion of the initial infector and downloader code in this campaign appears to be generated by large language model (LLM) agents." The findings demonstrate a new trend among cybercriminal groups to leverage artificial intelligence (AI) to bolster their tradecraft. Known to be active since at least 2015, RevengeHotels has a history of hospitality, hotel, and travel organizations in Latin America with the goal of installing malware on compromised syste...
