Fire Ant is assessed to share tooling and targeting overlaps with prior campaigns orchestrated by UNC3886 , a...

Cybersecurity researchers have shed light on a new versatile malware loader called CastleLoader that has been put to use in campaigns distributing various information stealers and remote access trojans (RATs). The activity employs Cloudflare-themed ClickFix phishing attacks and fake GitHub repositories opened under the names of legitimate applications, Swiss cybersecurity company PRODAFT said in a report shared with The Hacker News. The malware loader, first observed in the wild earlier this year, has been used to distribute DeerStealer , RedLine , StealC , NetSupport RAT , SectopRAT , and even other loaders like Hijack Loader . "It employs dead code injection and packing techniques to hinder analysis," the company said. "After unpacking itself at runtime, it connects to a C2 (command-and-control) server, downloads target modules, and executes them." CastleLoader's modular structure allows it to act as both a delivery mechanism and a staging utility, enabling...

You wouldn't run your blue team once a year, so why accept this substandard schedule for your offensive side? Your cybersecurity teams are under intense pressure to be proactive and to find your network's weaknesses before adversaries do. But in many organizations, offensive security is still treated as a one-time event: an annual pentest, a quarterly red team engagement, maybe an audit sprint before a compliance deadline . That's not defense. It's a theater. In the real world, adversaries don't operate in bursts. Their recon is continuous, their tools and tactics are always evolving, and new vulnerabilities are often reverse-engineered into working exploits within hours of a patch release.  So, if your offensive validation isn't just as dynamic, you're not just lagging, you're exposed. It's time to move beyond the once a year pentest. It's time to build an Offensive Security Operations Center . Why annual pentesting falls short Point-in-time penetration tests still serv...

The Tibetan community has been targeted by a China-nexus cyber espionage group as part of two campaigns conducted last month ahead of the Dalai Lama's 90th birthday on July 6, 2025. The multi-stage attacks have been codenamed Operation GhostChat and Operation PhantomPrayers by Zscaler ThreatLabz. "The attackers compromised a legitimate website, redirecting users via a malicious link and ultimately installing either the Gh0st RAT or PhantomNet (aka SManager) backdoor onto victim systems," security researchers Sudeep Singh and Roy Tay said in a Wednesday report. This is not the first time Chinese threat actors have resorted to watering hole attacks (aka strategic web compromises), a technique where adversaries break into websites frequently visited by a specific group to infect their devices with malware. Over the past two years, hacking groups like EvilBamboo , Evasive Panda , and TAG-112 have all resorted to the approach to target the Tibetan diaspora with the u...

Microsoft has revealed that one of the threat actors behind the active exploitation of SharePoint flaws is deploying Warlock ransomware on targeted systems. The tech giant, in an update shared Wednesday, said the findings are based on an "expanded analysis and threat intelligence from our continued monitoring of exploitation activity by Storm-2603 ." The threat actor attributed to the financially motivated activity is a suspected China-based threat actor that's known to drop Warlock and LockBit ransomware in the past. The attack chains entail the exploitation of CVE-2025-49706, a spoofing vulnerability, and CVE-2025-49704, a remote code execution vulnerability, targeting unpatched on-premises SharePoint servers to deploy the spinstall0.aspx web shell payload. "This initial access is used to conduct command execution using the w3wp.exe process that supports SharePoint," Microsoft said. "Storm-2603 then initiates a series of discovery commands, incl...

Europol on Monday announced the arrest of the suspected administrator of XSS.is (formerly DaMaGeLaB), a notorious Russian-speaking cybercrime platform. The arrest, which took place in Kyiv, Ukraine, on July 222, 2025, was led by the French Police and Paris Prosecutor, in collaboration with Ukrainian authorities and Europol. The action is the result of an investigation that was launched by the French Police in July 2021. Coupled with the arrest, law enforcement has also taken control of the clearnet domain of XSS.is, greeting visitors with a seizure notice, "This domain has been seized by la Brigade de Lutte Contre la Cybercriminalité with assistance of the SBU Cyber Department." "The forum, which had more than 50,000 registered users, served as a key marketplace for stolen data, hacking tools and illicit services," the law enforcement agency said . "It has long been a central platform for some of the most active and dangerous cybercriminal networks, used t...

Cybersecurity researchers have uncovered a new stealthy backdoor concealed within the "mu-plugins" directory in WordPress sites to grant threat actors persistent access and allow them to perform arbitrary actions. Must-use plugins (aka mu-plugins) are special plugins that are automatically activated on all WordPress sites in the installation. They are located in the "wp-content/mu-plugins" directory by default. What makes them an attractive option for attackers is that mu-plugins do not show in the default list of plugins on the Plugins page of wp-admin and cannot be disabled except by removing the plugin file from the must-use directory. As a result, a piece of malware that leverages this technique allows it to function quietly, without raising any red flags. In the infection spotted by web security company Sucuri, the PHP script in the mu-plugins directory ("wp-index.php") serves as a loader to fetch a next-stage payload and save it in the WordPr...

The threat actor behind the exploitation of vulnerable Craft Content Management System (CMS) instances has shifted its tactics to target Magento CMS and misconfigured Docker instances. The activity has been attributed to a threat actor tracked as Mimo (aka Hezb), which has a long history of leveraging N-day security flaws in various web applications to deploy cryptocurrency miners. "Although Mimo's primary motivation remains financial, through cryptocurrency mining and bandwidth monetization, the sophistication of their recent operations suggests potential preparation for more lucrative criminal activities," Datadog Security Labs said in a report published this week. Mimo's exploitation of CVE-2025-32432, a critical security flaw in Craft CMS, for cryptojacking and proxyjacking was documented by Sekoia in May 2025. Newly observed attack chains associated with the threat actor involve the abuse of undetermined PHP-FPM vulnerabilities in Magento e-commerce inst...

The Windows banking trojan known as Coyote has become the first known malware strain to exploit the Windows accessibility framework called UI Automation (UIA) to harvest sensitive information. "The new Coyote variant is targeting Brazilian users, and uses UIA to extract credentials linked to 75 banking institutes' web addresses and cryptocurrency exchanges," Akamai security researcher Tomer Peled said in an analysis. Coyote, first revealed by Kaspersky in 2024, is known for targeting Brazilian users. It comes with capabilities to log keystrokes, capture screenshots, and serve overlays on top of login pages associated with financial enterprises. Part of the Microsoft .NET Framework, UIA is a legitimate feature offered by Microsoft to allow screen readers and other assistive technology products to programmatically access user interface (UI) elements on a desktop.  That UIA can be a potential pathway for abuse, including data theft, was previously demonstrated as a...
