Cybersecurity researchers have warned of a surge in retaliatory hacktivist activity following the U.S.-Israel coordinated military campaign against Iran , codenamed Epic Fury and Roaring Lion. "The hacktivist threat in the Middle East is highly lopsided, with two groups, Keymous+ and DieNet, driving nearly 70% of all attack activity between February 28 and March 2," Radware said in a Tuesday report. The first distributed denial-of-service (DDoS) attack was launched by Hider Nex (aka Tunisian Maskers Cyber Force) on February 28, 2026. According to details shared by Orange Cyberdefense, Hider Nex is a shadowy Tunisian hacktivist group that supports pro-Palestinian causes. It leverages a hack-and-leak strategy combining DDoS attacks with data breaches to leak sensitive data and advance its geopolitical agenda. The group emerged in mid-2025. In all, a total of 149 hacktivist DDoS claims were recorded targeting 110 distinct organizations across 16 countries. The attacks were...

Google said it identified a "new and powerful" exploit kit dubbed Coruna (aka CryptoWaters) targeting Apple iPhone models running iOS versions between 13.0 and 17.2.1. The exploit kit featured five full iOS exploit chains and a total of 23 exploits, Google Threat Intelligence Group (GTIG) said. It's not effective against the latest version of iOS. The findings were first reported by WIRED. "The core technical value of this exploit kit lies in its comprehensive collection of iOS exploits, with the most advanced ones using non-public exploitation techniques and mitigation bypasses," according to GTIG. "The framework surrounding the exploit kit is extremely well engineered; the exploit pieces are all connected naturally and combined together using common utility and exploitation frameworks." The kit is said to have circulated among multiple threat actors since February 2025, moving from a commercial surveillance operation to a government-backed att...

Cybersecurity researchers have flagged malicious Packagist PHP packages masquerading as Laravel utilities that act as a conduit for a cross-platform remote access trojan (RAT) that's functional on Windows, macOS, and Linux systems. The names of the packages are listed below - nhattuanbl/lara-helper (37 Downloads) nhattuanbl/simple-queue (29 Downloads) nhattuanbl/lara-swagger (49 Downloads) According to Socket, the package "nhattuanbl/lara-swagger" does not directly embed malicious code, lists "nhattuanbl/lara-helper" as a Composer dependency , causing it to install the RAT. The packages are still available for download from the PHP package registry. Both lara-helper and simple-queue have been found to contain a PHP file named "src/helper.php," which employs a number of tricks to complicate static analysis by making use of techniques like control flow obfuscation, encoding domain names, command names, and file paths, and randomized identifie...

Cybersecurity researchers have disclosed details of an advanced persistent threat (APT) group dubbed Silver Dragon that has been linked to cyber attacks targeting entities in Europe and Southeast Asia since at least mid-2024. "Silver Dragon gains its initial access by exploiting public-facing internet servers and by delivering phishing emails that contain malicious attachments," Check Point said in a technical report. "To maintain persistence, the group hijacks legitimate Windows services, which allows the malware processes to blend into normal system activity." Silver Dragon is assessed to be operating within the APT41 umbrella . APT41 is the cryptonym assigned to a prolific Chinese hacking group known for its targeting of healthcare, telecoms, high-tech, education, travel services, and media sectors for cyber espionage as early as 2012. It's also believed to engage in financially motivated activity potentially outside of state control. Attacks mounted by...

Threat hunters have called attention to a new campaign as part of which bad actors masqueraded as fake IT support to deliver the Havoc command-and-control (C2) framework as a precursor to data exfiltration or ransomware attack. The intrusions, identified by Huntress last month across five partner organizations, involved the threat actors using email spam as lures, followed by a phone call from an IT desk that activates a layered malware delivery pipeline. "In one organization, the adversary moved from initial access to nine additional endpoints over the course of eleven hours, deploying a mix of custom Havoc Demon payloads and legitimate RMM tools for persistence, with the speed of lateral movement strongly suggesting the end goal was data exfiltration, ransomware, or both," researchers Michael Tigges, Anna Pham, and Bryan Masters said. It's worth noting that the modus operandi is consistent with email bombing and Microsoft Teams phishing attacks orchestrated by t...

Every CISO knows the uncomfortable truth about their Security Operations Center: the people most responsible for catching threats in real time are the people with the least experience. Tier 1 analysts sit at the front line of detection, and yet they are also the most vulnerable to the cognitive and organizational pressures that quietly erode SOC performance over time. The Paradox at the Gate: Why Tier 1 Carries the Weight but Lacks the Armor Tier 1 is the layer that processes the highest volume of alerts, performs initial triage, and determines what gets escalated. But it is built on a foundation that is structurally fragile. Entry-level analysts, high turnover rates, and relentless alert queues create conditions where even well-designed detection rules fail to translate into timely, accurate responses. The paradox is here:  Tier 1 performance defines SOC performance; But Tier 1 is often the least supported, least empowered, and most cognitively overloaded layer Tier 1 an...

The threat actor behind the recently disclosed artificial intelligence (AI)-assisted campaign targeting Fortinet FortiGate appliances leveraged an open-source, AI-native security testing platform called CyberStrikeAI to execute the attacks. The new findings come from Team Cymru, which detected its use following an analysis of the IP address ("212.11.64[.]250") that was used by the suspected Russian-speaking threat actor to conduct automated mass scanning for vulnerable appliances. CyberStrikeAI is an "open-source artificial intelligence (AI) offensive security tool (OST) developed by a China-based developer who we assess has some ties to the Chinese government," security researcher Will Thomas (aka @BushidoToken ) said . Details of the AI-powered activity came to light last month when Amazon Threat Intelligence said it detected the unknown attacker systematically targeting FortiGate devices using generative artificial intelligence (AI) services like Anthropic ...

Cybersecurity researchers have disclosed details of a new phishing suite called Starkiller that proxies legitimate login pages to bypass multi-factor authentication (MFA) protections. It's advertised as a cybercrime platform by a threat group calling itself Jinkusu, granting customers access to a dashboard that lets them select a brand to impersonate or enter a brand's real URL. It also lets users choose custom keywords like "login," "verify," "security," or "account," and integrates URL shorteners such as TinyURL to obscure the destination URL. "It launches a headless Chrome instance – a browser that operates without a visible window – inside a Docker container , loads the brand's real website, and acts as a reverse proxy between the target and the legitimate site," Abnormal researchers Callie Baron and Piotr Wojtyla said . "Recipients are served genuine page content directly through the attacker's infrastruc...

A recently disclosed security flaw patched by Microsoft may have been exploited by the Russia-linked state-sponsored threat actor known as APT28 , according to new findings from Akamai. The vulnerability in question is CVE-2026-21513 (CVSS score: 8.8), a high-severity security feature bypass affecting the MSHTML Framework. "Protection mechanism failure in MSHTML Framework allows an unauthorized attacker to bypass a security feature over a network," Microsoft noted in its advisory for the flaw. It was fixed by the Windows maker as part of its February 2026 Patch Tuesday update. However, the tech giant also noted that the vulnerability had been exploited as a zero-day in real-world attacks, crediting the Microsoft Threat Intelligence Center (MSTIC), Microsoft Security Response Center (MSRC), and Office Product Group Security Team, along with Google Threat Intelligence Group (GTIG), for reporting it. In a hypothetical attack scenario, a threat actor could weaponize th...

Cybersecurity researchers have disclosed details of a malicious Go module that's designed to harvest passwords, create persistent access via SSH, and deliver a Linux backdoor named Rekoobe. The Go module, github[.]com/xinfeisoft/crypto, impersonates the legitimate "golang.org/x/crypto" codebase, but injects malicious code that's responsible for exfiltrating secrets entered via terminal password prompts to a remote endpoint, fetches a shell script in response, and executes it. "This activity fits namespace confusion and impersonation of the legitimate golang.org/x/crypto subrepository (and its GitHub mirror github.com/golang/crypto)," Socket security researcher Kirill Boychenko said . "The legitimate project identifies go.googlesource.com/crypto as canonical and treats GitHub as a mirror, a distinction the threat actor abuses to make github.com/xinfeisoft/crypto look routine in dependency graphs." Specifically, the backdoor has been placed with...

Threat actors are luring unsuspecting users into running trojanized gaming utilities that are distributed via browsers and chat platforms to distribute a remote access trojan (RAT). "A malicious downloader staged a portable Java runtime and executed a malicious Java archive (JAR) file named jd-gui.jar," the Microsoft Threat Intelligence team said in a post on X. "This downloader used PowerShell and living-off-the-land binaries (LOLBins) like cmstp.exe for stealthy execution." The attack chain is also designed to evade detection by deleting the initial downloader and by configuring Microsoft Defender exclusions for the RAT components. Persistence is achieved by means of a scheduled task and Windows startup script named "world.vbs," before the final payload is deployed on the compromised host. The malware, per Microsoft, is a "multi-purpose malware" that acts as a loader, runner, downloader, and RAT. Once launched, it connects to an external ...

A previously undocumented threat activity cluster has been attributed to an ongoing malicious campaign targeting education and healthcare sectors in the U.S. since at least December 2025. The campaign is being tracked by Cisco Talos under the moniker UAT-10027 . The end goal of the attacks is to deliver a never-before-seen backdoor codenamed Dohdoor. "Dohdoor utilizes the DNS-over-HTTPS (DoH) technique for command-and-control (C2) communications and has the ability to download and execute other payload binaries reflectively," security researchers Alex Karkins and Chetan Raghuprasad said in a technical report shared with The Hacker News. Although the initial access vector used in the campaign is currently not known, it's suspected to involve the use of social engineering phishing techniques, leading to the execution of a PowerShell script. The script then proceeds to download and run a Windows batch script from a remote staging server, which, for its part, facilitat...

Google on Wednesday disclosed that it worked with industry partners to disrupt the infrastructure of a suspected China-nexus cyber espionage group tracked as UNC2814 that breached at least 53 organizations across 42 countries. "This prolific, elusive actor has a long history of targeting international governments and global telecommunications organizations across Africa, Asia, and the Americas," Google Threat Intelligence Group (GTIG) and Mandiant said in a report published today. UNC2814 is also suspected to be linked to additional infections in more than 20 other nations. The tech giant, which has been tracking the threat actor since 2017, has been observed using API calls to communicate with software-as-a-service (SaaS) apps as command-and-control (C2) infrastructure. The idea, it added, is to disguise their malicious traffic as benign. Central to the hacking group's operations is a novel backdoor dubbed GRIDTIDE that abuses Google Sheets API as a communication ...

The notorious cybercrime collective known as Scattered LAPSUS$ Hunters (SLH) has been observed offering financial incentives to recruit women to pull off social engineering attacks. The idea is to hire them for voice phishing campaigns targeting IT help desks, Dataminr said in a new threat brief. The group is said to be offering anywhere between $500 and $1,000 upfront per call, in addition to providing them with the necessary pre-written scripts to carry out the attack. "SLH is diversifying its social engineering pool by specifically recruiting women to conduct vishing attacks, likely to increase the success rate of help desk impersonation," the threat intelligence firm said . A high-profile cybercrime supergroup comprising LAPSUS$, Scattered Spider, and ShinyHunters, SLH has a record of engaging in advanced social engineering attacks to sidestep multi-factor authentication (MFA) through techniques like MFA prompt bombing and SIM swapping.  The group's modus ope...

A Russia-aligned threat actor has been observed targeting a European financial institution as part of a social engineering attack to likely facilitate intelligence gathering or financial theft, signaling a possible expansion of the threat actor's targeting beyond Ukraine and into entities supporting the war-torn nation . The activity, which targeted an unnamed entity involved in regional development and reconstruction initiatives, has been attributed to a cybercrime group tracked as UAC-0050 (aka DaVinci Group ). BlueVoyant has designated the name Mercenary Akula to the threat cluster. The attack was observed earlier this month. "The attack spoofed a Ukrainian judicial domain to deliver an email containing a link to a remote access payload," researchers Patrick McHale and Joshua Green said in a report shared with The Hacker News. "The target was a senior legal and policy advisor involved in procurement, a role with privileged insight into institutional operation...

The North Korea-linked Lazarus Group (aka Diamond Sleet and Pompilus) has been observed using Medusa ransomware in an attack targeting an unnamed entity in the Middle East, according to a new report by the Symantec and Carbon Black Threat Hunter Team. Broadcom's threat intelligence division said it also identified the same threat actors mounting an unsuccessful attack against a healthcare organization in the U.S. Medusa is a ransomware-as-a-service (RaaS) operation launched by a cybercrime group known as Spearwing in 2023. The group has claimed more than 366 attacks to date. "Analysis of the Medusa leak site reveals attacks against four healthcare and non-profit organizations in the U.S. since the beginning of November 2025," the company said in a report shared with The Hacker News. "Victims included a non-profit in the mental health sector and an educational facility for autistic children. It is unknown if all these victims were targeted by North Korean opera...

The threat activity cluster known as UnsolicitedBooker has been observed targeting telecommunications companies in Kyrgyzstan and Tajikistan, marking a shift from prior attacks aimed at Saudi Arabian entities. The attacks involve the deployment of two distinct backdoors codenamed LuciDoor and MarsSnake, according to a report published by Positive Technologies last week. "The group used several unique and rare instruments of Chinese origin," researchers Alexander Badaev and Maxim Shamanov said . UnsolicitedBooker was first documented by ESET in May 2025, attributing the China-aligned threat actor to a cyber attack targeting an unnamed international organization in Saudi Arabia with a backdoor dubbed MarsSnake. The group is assessed to be active since at least March 2023 and has a history of targeting organizations in Asia, Africa, and the Middle East. Further analysis of the threat actor has uncovered tactical overlaps with two other clusters, including Space Pirates an...

The Russia-linked state-sponsored threat actor tracked as APT28 has been attributed to a new campaign targeting specific entities in Western and Central Europe. The activity, per S2 Grupo's LAB52 threat intelligence team, was active between September 2025 and January 2026. It has been codenamed Operation MacroMaze . "The campaign relies on basic tooling and the exploitation of legitimate services for infrastructure and data exfiltration," the cybersecurity company said . The attack chains employ spear-phishing emails as a starting point to distribute lure documents that contain a common structural element within their XML, a field named "INCLUDEPICTURE" that points to a webhook[.]site URL that hosts a JPG image. This, in turn, causes the image file to be fetched from the remote server when the document is opened. Put differently, this mechanism acts as a beaconing mechanism akin to a tracking pixel that triggers an outbound HTTP request to the webhook[.]si...

Cybersecurity researchers have disclosed details of a new cryptojacking campaign that uses pirated software bundles as lures to deploy a bespoke XMRig miner program on compromised hosts. "Analysis of the recovered dropper, persistence triggers, and mining payload reveals a sophisticated, multi-stage infection prioritizing maximum cryptocurrency mining hashrate, often destabilizing the victim system," Trellix researcher Aswath A said in a technical report published last week. "Furthermore, the malware exhibits worm-like capabilities, spreading across external storage devices, enabling lateral movement even in air-gapped environments." The entry point of the attack is the use of social engineering decoys, advertising free premium software in the form of pirated software bundles, such as installers for office productivity suites, to trick unsuspecting users into downloading malware-laced executables. The binary acts as the central nervous system of the infectio...

The Iranian hacking group known as MuddyWater (aka Earth Vetala, Mango Sandstorm, and MUDDYCOAST) has targeted several organizations and individuals mainly located across the Middle East and North Africa (MENA) region as part of a new campaign codenamed Operation Olalampo . The activity, first observed on January 26, 2026, has resulted in the deployment of new malware families that share overlapping samples previously identified as used by the threat actor, according to a report published by Group-IB. These include downloaders like GhostFetch and HTTP_VIP, along with a Rust backdoor called CHAR and an advanced implant codenamed GhostBackDoor that's dropped by GhostFetch. "These attacks follow similar patterns and align with the killchains previously observed in MuddyWater attacks; starting with a phishing email with a Microsoft Office document attached to it that contains malicious macro code that decodes the embedded payload and drops it on the system and executes it, pro...
