A new analysis has uncovered connections between affiliates of RansomHub and other ransomware groups like Medusa , BianLian , and Play . The connection stems from the use of a custom tool that's designed to disable endpoint detection and response (EDR) software on compromised hosts, according to ESET. The EDR killing tool, dubbed EDRKillShifter , was first documented as used by RansomHub actors in August 2024. EDRKillShifter accomplishes its goals by means of a known tactic called Bring Your Own Vulnerable Driver (BYOVD) that involves using a legitimate but vulnerable driver to terminate security solutions protecting the endpoints. The idea behind using such tools is to ensure the smooth execution of the ransomware encryptor without it being flagged by security solutions. "During an intrusion, the goal of the affiliate is to obtain admin or domain admin privileges," ESET researchers Jakub Souček and Jan Holman said in a report shared with The Hacker News. "...

An advanced persistent threat (APT) group with ties to Pakistan has been attributed to the creation of a fake website masquerading as India's public sector postal system as part of a campaign designed to infect both Windows and Android users in the country. Cybersecurity company CYFIRMA has attributed the campaign with medium confidence to a threat actor called APT36 , which is also known as Transparent Tribe.  The fraudulent website mimicking India Post is named "postindia[.]site." Users who land on the site from Windows systems are prompted to download a PDF document, whereas those visiting from an Android device are served a malicious application package ("indiapost.apk") file. "When accessed from a desktop, the site delivers a malicious PDF file containing ' ClickFix ' tactics," CYFIRMA said . "The document instructs users to press the Win + R keys, paste a provided PowerShell command into the Run dialog, and execute it – potentia...

Whether it’s CRMs, project management tools, payment processors, or lead management tools - your workforce is using SaaS applications by the pound.

Hackers have long used Word and Excel documents as delivery vehicles for malware, and in 2025, these tricks are far from outdated. From phishing schemes to zero-click exploits, malicious Office files are still one of the easiest ways into a victim’s system. Here are the top three Microsoft Office-based exploits still making the rounds this year and what you need to know to avoid them. 1. Phishing in MS Office: Still Hackers' Favorite Phishing attacks using Microsoft Office files have been around for years, and they're still going strong. Why? Because they work, especially in business environments where teams constantly exchange Word and Excel documents. Attackers know that people are used to opening Office files, especially if they come from what looks like a colleague, a client, or a partner. A fake invoice, a shared report, or a job offer: it doesn't take much to convince someone to click. And once the file is open, the attacker has their chance. Phishing with Offic...

An ongoing campaign that infiltrates legitimate websites with malicious JavaScript injects to promote Chinese-language gambling platforms has ballooned to compromise approximately 150,000 sites to date. "The threat actor has slightly revamped their interface but is still relying on an iframe injection to display a full-screen overlay in the visitor's browser," c/side security analyst Himanshu Anand said in a new analysis. As of writing, there are over 135,800 sites containing the JavaScript payload, per statistics from PublicWWW. As documented by the website security company last month, the campaign involves infecting websites with malicious JavaScript that's designed to hijack the user's browser window to redirect site visitors to pages promoting gambling platforms. The redirections have been found to occur via JavaScript hosted on five different domains (e.g., "zuizhongyj[.]com") that, in turn, serve the main payload responsible for performing...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added two six-year-old security flaws impacting Sitecore CMS and Experience Platform (XP) to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerabilities are listed below - CVE-2019-9874 (CVSS score: 9.8) - A deserialization vulnerability in the Sitecore.Security.AntiCSRF module that allows an unauthenticated attacker to execute arbitrary code by sending a serialized .NET object in the HTTP POST parameter __CSRFTOKEN CVE-2019-9875 (CVSS score: 8.8) - A deserialization vulnerability in the Sitecore.Security.AntiCSRF module that allows an authenticated attacker to execute arbitrary code by sending a serialized .NET object in the HTTP POST parameter __CSRFTOKEN There are currently no details on how the flaws are being weaponized in the wild and by whom, although SiteCore, in an update shared on March 30, 2020, said it became "aware of active exploit...

A critical security flaw has been disclosed in NetApp SnapCenter that, if successfully exploited, could allow privilege escalation. SnapCenter is an enterprise-focused software that's used to manage data protection across applications, databases, virtual machines, and file systems, offering the ability to backup, restore, and clone data resources. The vulnerability, tracked as CVE-2025-26512 , carries a CVSS score of 9.9 out of a maximum of 10.0. "SnapCenter versions prior to 6.0.1P1 and 6.1P1 are susceptible to a vulnerability which may allow an authenticated SnapCenter Server user to become an admin user on a remote system where a SnapCenter plug-in has been installed," the data infrastructure company said in an advisory published this week. CVE-2025-26512 has been addressed in SnapCenter versions 6.0.1P1 and 6.1P1. There are currently no workarounds that address the issue.  While there is no evidence that the shortcoming has been exploited in the wild, it'...
