Cybersecurity company Huntress on Friday warned of "widespread compromise" of SonicWall SSL VPN devices to access multiple customer environments. "Threat actors are authenticating into multiple accounts rapidly across compromised devices," it said . "The speed and scale of these attacks imply that the attackers appear to control valid credentials rather than brute-forcing." A significant chunk of the activity is said to have commenced on October 4, 2025, with more than 100 SonicWall SSL VPN accounts across 16 customer accounts having been impacted. In the cases investigated by Huntress, authentications on the SonicWall devices originated from the IP address 202.155.8[.]73. The company noted that in some instances, the threat actors did not engage in further adversarial actions in the network and disconnected after a short period of time. However, in other cases, the attackers have been found conducting network scanning activity and attempting to access...

Threat actors are abusing Velociraptor, an open-source digital forensics and incident response (DFIR) tool, in connection with ransomware attacks likely orchestrated by Storm-2603 (aka CL-CRI-1040 or Gold Salem), which is known for deploying the Warlock and LockBit ransomware. The threat actor's use of the security utility was documented by Sophos last month. It's assessed that the attackers weaponized the on-premises SharePoint vulnerabilities known as ToolShell to obtain initial access and deliver an outdated version of Velociraptor (version 0.73.4.0) that's susceptible to a privilege escalation vulnerability ( CVE-2025-6264 ) to enable arbitrary command execution and endpoint takeover, per Cisco Talos . In the attack in mid-August 2025, the threat actors are said to have made attempts to escalate privileges by creating domain admin accounts and moving laterally within the compromised environment, as well as leveraging the access to run tools like Smbexec to remotely...

Cybersecurity researchers have disclosed details of an active malware campaign called Stealit that has leveraged Node.js' Single Executable Application (SEA) feature as a way to distribute its payloads. According to Fortinet FortiGuard Labs, select iterations have also employed the open-source Electron framework to deliver the malware. It's assessed that the malware is being propagated through counterfeit installers for games and VPN applications that are uploaded to file-sharing sites such as Mediafire and Discord. SEA is a feature that allows Node.js applications to be packaged and distributed as a standalone executable, even on systems without Node.js installed. "Both approaches are effective for distributing Node.js-based malware, as they allow execution without requiring a pre-installed Node.js runtime or additional dependencies," security researchers Eduardo Altares and Joie Salvio said in a report shared with The Hacker News. On a dedicated website, the...

A threat actor known as Storm-2657 has been observed hijacking employee accounts with the end goal of diverting salary payments to attacker-controlled accounts. "Storm-2657 is actively targeting a range of U.S.-based organizations, particularly employees in sectors like higher education, to gain access to third-party human resources (HR) software as a service (SaaS) platforms like Workday," the Microsoft Threat Intelligence team said in a report. However, the tech giant cautioned that any software-as-a-service (SaaS) platform storing HR or payment and bank account information could be a target of such financially motivated campaigns. Some aspects of the campaign, codenamed Payroll Pirates , were previously highlighted by Silent Push, Malwarebytes, and Hunt.io. What makes the attacks notable is that they don't exploit any security flaw in the services themselves. Rather, they leverage social engineering tactics and a lack of multi-factor authentication (MFA) protect...

Fortra on Thursday revealed the results of its investigation into CVE-2025-10035 , a critical security flaw in GoAnywhere Managed File Transfer (MFT) that's assessed to have come under active exploitation since at least September 11, 2025. The company said it began its investigation on September 11 following a "potential vulnerability" reported by a customer, uncovering "potentially suspicious activity" related to the flaw.  That same day, Fortra said it contacted on-premises customers who were identified as having their GoAnywhere admin console accessible to the public internet and that it notified law enforcement authorities about the incident. A hotfix for versions 7.6.x, 7.7.x, and 7.8.x of the software was made available the next day, with full releases incorporating the patch – versions 7.6.3 and 7.8.4 – made available on September 15. Three days later, a CVE for the vulnerability was formally published, it added. "The scope of the risk of this...
