Threat actors are using the "mu-plugins" directory in WordPress sites to conceal malicious code with the goal of maintaining persistent remote access and redirecting site visitors to bogus sites. mu-plugins, short for must-use plugins, refers to plugins in a special directory ("wp-content/mu-plugins") that are automatically executed by WordPress without the need to enable them explicitly via the

Every week, someone somewhere slips up—and threat actors slip in. A misconfigured setting, an overlooked vulnerability, or a too-convenient cloud tool becomes the perfect entry point. But what happens when the hunters become the hunted? Or when old malware resurfaces with new tricks? Step behind the curtain with us this week as we explore breaches born from routine oversights—and the unexpected

If you're using AWS, it's easy to assume your cloud security is handled - but that's a dangerous misconception. AWS secures its own infrastructure, but security within a cloud environment remains the customer’s responsibility. Think of AWS security like protecting a building: AWS provides strong walls and a solid roof, but it's up to the customer to handle the locks, install the alarm systems,

Entities in Ukraine have been targeted as part of a phishing campaign designed to distribute a remote access trojan called Remcos RAT. "The file names use Russian words related to the movement of troops in Ukraine as a lure," Cisco Talos researcher Guilherme Venere said in a report published last week. "The PowerShell downloader contacts geo-fenced servers located in Russia and Germany to

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has shed light on a new malware called RESURGE that has been deployed as part of exploitation activity targeting a now-patched security flaw in Ivanti Connect Secure (ICS) appliances. "RESURGE contains capabilities of the SPAWNCHIMERA malware variant, including surviving reboots; however, RESURGE contains distinctive commands that

Cybersecurity researchers have discovered a new Android banking malware called Crocodilus that's primarily designed to target users in Spain and Turkey. "Crocodilus enters the scene not as a simple clone, but as a fully-fledged threat from the outset, equipped with modern techniques such as remote control, black screen overlays, and advanced data harvesting via accessibility logging,"

In what's an instance of hacking the hackers, threat hunters have managed to infiltrate the online infrastructure associated with a ransomware group called BlackLock, uncovering crucial information about their modus operandi in the process. Resecurity said it identified a security vulnerability in the data leak site (DLS) operated by the e-crime group that made it possible to extract

Cybersecurity researchers have disclosed 46 new security flaws in products from three solar inverter vendors, Sungrow, Growatt, and SMA, that could be exploited by a bad actor to seize control of devices or execute code remotely, posing severe risks to electrical grids.  The vulnerabilities have been collectively codenamed SUN:DOWN by Forescout Vedere Labs. "The new vulnerabilities can be

Cybersecurity researchers are calling attention to a new sophisticated malware called CoffeeLoader that's designed to download and execute secondary payloads. The malware, according to Zscaler ThreatLabz, shares behavioral similarities with another known malware loader known as SmokeLoader.  "The purpose of the malware is to download and execute second-stage payloads while evading

Long gone are the days when a simple backup in a data center was enough to keep a business secure. While backups store information, they do not guarantee business continuity during a crisis. With IT disasters far too common and downtime burning through budgets, modern IT environments require solutions that go beyond storage and enable instant recovery to minimize downtime and data loss. This is

An Android malware family previously observed targeting Indian military personnel has been linked to a new campaign likely aimed at users in Taiwan under the guise of chat apps. "PJobRAT can steal SMS messages, phone contacts, device and app information, documents, and media files from infected Android devices," Sophos security researcher Pankaj Kohli said in a Thursday analysis. PJobRAT, first

Cybersecurity researchers have discovered several cryptocurrency packages on the npm registry that have been hijacked to siphon sensitive information such as environment variables from compromised systems. "Some of these packages have lived on npmjs.com for over 9 years, and provide legitimate functionality to blockchain developers," Sonatype researcher Ax Sharma said. "However, [...] the latest

Mozilla has released updates to address a critical security flaw impacting its Firefox browser for Windows, merely days after Google patched a similar flaw in Chrome that came under active exploitation as a zero-day. The security vulnerability, CVE-2025-2857, has been described as a case of an incorrect handle that could lead to a sandbox escape. "Following the recent Chrome sandbox escape (

Cybersecurity researchers have shed light on a new phishing-as-a-service (PhaaS) platform that leverages the Domain Name System (DNS) mail exchange (MX) records to serve fake login pages that impersonate about 114 brands. DNS intelligence firm Infoblox is tracking the actor behind the PhaaS, the phishing kit, and the related activity under the moniker Morphing Meerkat. "The threat actor behind

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

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

Whether it’s CRMs, project management tools, payment processors, or lead management tools - your workforce is using SaaS applications by the pound. Organizations often rely on traditional CASB solutions for protecting against malicious access and data exfiltration, but these fall short for protecting against shadow SaaS, data damage, and more. A new report, Understanding SaaS Security Risks: Why

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.

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

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
