Cybersecurity researchers have disclosed details of an intrusion that involved the use of a CloudZ remote access tool (RAT) and a previous undocumented plugin dubbed Pheno with the aim of facilitating credential theft. "According to the functionalities of the CloudZ RAT and Pheno plugin, this was with the intention of stealing victims' credentials and potentially one-time passwords (OTPs)," Cisco Talos researchers Alex Karkins and Chetan Raghuprasad said in a Tuesday analysis. What makes the attack novel is that CloudZ uses the custom Pheno plugin to hijack the established PC-to-phone bridge by abusing the Microsoft Phone Link application, permitting the plugin to monitor for active Phone Link processes and potentially intercept sensitive mobile data like SMS and one-time passwords (OTPs) without the need for deploying malware on the phone.  The findings demonstrate how legitimate cross-device syncing features can expose unintended attack pathways to credential theft...

Palo Alto Networks has released an advisory warning that a critical buffer overflow vulnerability in its PAN-OS software has been exploited in the wild. The vulnerability, tracked as CVE-2026-0300 , has been described as a case of unauthenticated remote code execution. It carries a CVSS score of 9.3 if the User-ID Authentication Portal is configured to enable access from the internet or any untrusted network. The severity comes down to 8.7 if access to the portal is restricted to only trusted internal IP addresses. "A buffer overflow vulnerability in the User-ID Authentication Portal (aka Captive Portal) service of Palo Alto Networks PAN-OS software allows an unauthenticated attacker to execute arbitrary code with root privileges on the PA-Series and VM-Series firewalls by sending specially crafted packets," the company said . According to Palo Alto Networks, the vulnerability has come under "limited exploitation," specifically targeting instances where the Use...

A newly identified supply chain attack targeting DAEMON Tools software has compromised its installers to serve a malicious payload, according to findings from Kaspersky. "These installers are distributed from the legitimate website of DAEMON Tools and are signed with digital certificates belonging to DAEMON Tools developers," Kaspersky researchers  Igor Kuznetsov, Georgy Kucherin, Leonid Bezvershenko, and Anton Kargin said . The installers have been trojanized since April 8, 2026, with versions ranging from 12.5.0.2421 to 12.5.0.2434 identified as compromised as part of the incident. While DAEMON Tools is also available for Mac, Kaspersky told The Hacker News that only the Windows version was compromised. The supply chain attack is active as of writing. AVB Disc Soft, the developer of the software, has been notified of the breach. Specifically, three different components of DAEMON Tools have been tampered with - DTHelper.exe DiscSoftBusServiceLite.exe DTShellHlp.exe ...

A sophisticated China-nexus advanced persistent threat (APT) group has been attributed to attacks targeting government entities in South America since at least late 2024 and government agencies in southeastern Europe in 2025. The activity is being tracked by Cisco Talos under the moniker UAT-8302 , with post-exploitation involving the deployment of custom-made malware families that have been put to use by other China-aligned hacking groups. Notable among the malware families is a .NET-based backdoor dubbed NetDraft (aka NosyDoor), a C# variant of FINALDRAFT (aka Squidoor) that has been previously linked to threat clusters known as Ink Dragon , CL-STA-0049, Earth Alux , Jewelbug , and REF7707 . ESET is tracking the use of NosyDoor to a group it calls LongNosedGoblin . Interestingly, the same malware has also been deployed against Russian IT organizations by a threat actor referred to as Erudite Mogwai (aka Space Pirates and Webworm), per Russian cybersecurity company Solar, which...

Every AI tool, workflow automation, and productivity app your employees connected to Google or Microsoft this year left something behind: a persistent OAuth token with no expiration date, no automatic cleanup, and in most organizations, no one watching it. Your perimeter controls don't see it. Your MFA doesn't stop it. And when an attacker gets hold of one, they don't need a password. OAuth grants don't expire when employees leave. They don't reset when passwords change. And in most organizations, nobody is watching them. The model made sense when a handful of IT-approved apps needed calendar access. It doesn't hold up when every employee is independently wiring AI tools, workflow automations, and productivity apps directly into their Google or Microsoft environment — each one receiving a persistent, scoped token with no automatic expiration and no centralized visibility. That's not a misconfiguration. It's how OAuth is designed to work. The gap is t...

The North Korea-aligned state-sponsored hacking group known as ScarCruft has compromised a video game platform in a supply chain espionage attack, trojanizing its components with a backdoor called BirdCall to likely target ethnic Koreans residing in China. While prior versions of the backdoor have primarily targeted Windows users only, the supply chain attack is assessed to have enabled the threat actors to also target Android devices, essentially turning it into a multi-platform threat. According to ESET, the campaign has singled out sqgame[.]net, a gaming platform used by ethnic Koreans living in the Yanbian region in China bordering North Korea and Russia. It's also known to act as a primary, high-risk transit point for North Korean defectors crossing the Tumen River. Filip Jurčacko, senior malware researcher at ESET, told The Hacker News that the campaign was discovered in October 2025, adding the trojanized Android games are still available for download on the sqgame[.]ne...

A critical security vulnerability in Weaver (Fanwei) E-cology , an enterprise office automation (OA) and collaboration platform, has come under active exploitation in the wild. The vulnerability ( CVE-2026-22679 , CVSS score: 9.8) relates to a case of unauthenticated remote code execution affecting Weaver E-cology 10.0 versions prior to 20260312. The issue resides in the "/papi/esearch/data/devops/dubboApi/debug/method" endpoint that allows an attacker to execute arbitrary commands by invoking exposed debug functionality. "Attackers can craft POST requests with attacker-controlled interfaceName and methodName parameters to reach command-execution helpers and achieve arbitrary command execution on the system," according to a description of the flaw in the NIST National Vulnerability Database (NVD). The advisory also noted that the Shadowserver Foundation observed the first signs of active exploitation on March 31, 2026. A similar alert published by QiAnXin on M...

Microsoft has disclosed details of a large-scale credential theft campaign that has leveraged a combination of code of conduct-themed lures and legitimate email services to direct users to attacker-controlled domains and steal authentication tokens. The multi-stage campaign, observed between April 14 and 16, 2026, targeted more than 35,000 users across over 13,000 organizations in 26 countries, with 92% of the targets located in the U.S. The majority of phishing emails were directed against healthcare and life sciences (19%), financial services (18%), professional services (11%), and technology and software (11%) sectors. "The lures in this campaign used polished, enterprise-style HTML templates with structured layouts and preemptive authenticity statements, making them appear more credible than typical phishing emails and increasing their plausibility as legitimate internal communications," the Microsoft Defender Security Research Team and Microsoft Threat Intelligence sa...

An active phishing campaign has been observed targeting multiple vectors since at least April 2025 with legitimate Remote Monitoring and Management (RMM) software as a way to establish persistent remote access to compromised hosts. The activity, codenamed VENOMOUS#HELPER , has impacted over 80 organizations, most of which are in the U.S., according to Securonix. It shares overlaps with clusters previously tracked by Red Canary and Sophos, the latter of which has given it the moniker STAC6405 . While it's not clear who is behind the campaign, the cybersecurity company said it aligns with a financially motivated Initial Access Broker (IAB) or a ransomware precursor operation. "In this case, a customized SimpleHelp and ScreenConnect RMMs are used to bypass defenses as they are legitimately installed by the unsuspecting victim," researchers Akshay Gaikwad, Shikha Sangwan, and Aaron Beardslee said in a report shared with The Hacker News. Setting aside the fact that the ...

"Exploitation may lead to unauthorized access, administrative control, and data exposure." The shortcomings affect the following versions - MOVEit Autom...

On December 4, 2025, a 17-year-old was arrested in Osaka under Japan’s Unauthorized Access Prohibition Act. The young man had run malicious code to extract the personal data of over 7 million users of Kaikatsu Club , Japan's largest internet cafe chain. When asked, the young man shared his motivation for the hack: he wanted to buy Pokémon cards. In a sense, this is a fairly conventional story. Since the 1990s, we’ve read about computing wunderkinds such as Kevin Mitnick, whose technical ability exceeded their judgment and who were drawn into high-profile cybercrimes in pursuit of status, profit, or excitement. But something is different in this story: the young man in question wasn’t technical. The rise of AI-assisted attacks In 2025, LLM-backed chat and agent systems crossed a threshold, going from useful but error-prone coding assistants to end-to-end coding powerhouses. Throughout the year, several measures of cybercrime frequency and severity approximately doubled. Instanc...

The China-based cybercrime group known as Silver Fox (aka Monarch, SwimSnake, The Great Thief of Valley, UTG-Q-1000, and Void Arachne) has been linked to a new campaign targeting organizations in Russia and India with a new malware called ABCDoor . The activity involved using phishing emails that mimic correspondence from the Income Tax Department of India in December 2025, followed by a similar campaign aimed at Russian entities in January 2026. "Both waves followed a nearly identical structure: phishing emails were styled as official notices regarding tax audits or prompted users to download an archive containing a 'list of tax violations,'" Kaspersky said . "Inside the archive was a modified Rust-based loader pulled from a public repository. This loader would download and execute the well-known ValleyRAT backdoor." The campaign is estimated to have impacted organizations across the industrial, consulting, retail, and transportation sectors. More th...

A coordinated international operation involving U.S. and Chinese authorities has arrested at least 276 suspects and shut down nine scam centers used for cryptocurrency investment fraud schemes targeting Americans, resulting in millions of dollars in losses. The crackdown was led by the Dubai Police, under the United Arab Emirates (UAE) Ministry of Interior, in partnership with the U.S. Federal Bureau of Investigation (FBI) and the Chinese Ministry of Public Security. Among those arrested are individuals from Burma and Indonesia, who were apprehended by authorities from Dubai and Thailand. Thet Min Nyi, 27, Wiliang Awang, 23, Andreas Chandra, 29, Lisa Mariam, 29, and two fugitive co-conspirators have been charged with federal fraud and money laundering charges in the U.S. "Fraudsters who target Americans from overseas cannot operate with impunity, no matter where in the world they reside," Assistant Attorney General A. Tysen Duva of the Justice Department's (DoJ) Crimi...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added a recently disclosed security flaw impacting various Linux distributions to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation in the wild. The vulnerability, tracked as CVE-2026-31431 (CVSS score: 7.8), is a case of local privilege escalation (LPE) flaw that could allow an unprivileged local user to obtain root. The nine-year-old flaw is also tracked as Copy Fail by Theori and Xint. Fixes have been made available in Linux kernel versions 6.18.22, 6.19.12, and 7.0. "Linux Kernel contains an incorrect resource transfer between spheres vulnerability that could allow for privilege escalation," CISA said in an advisory. In a write-up published earlier this week, the researchers said Copy Fail is the result of a logic bug in the Linux kernel's authentication cryptographic template that allows an attacker to reliably trigger privilege escalation tri...

A newly discovered Vietnamese-linked operation has been observed using a Google AppSheet as a "phishing relay" to distribute phishing emails with an aim to compromise Facebook accounts. The activity has been codenamed AccountDumpling by Guardio, with the scheme selling the stolen accounts back through an illicit storefront run by the threat actors. In all, roughly 30,000 Facebook accounts are estimated to have been hacked as part of the campaign. "What we found wasn't a single phishing kit," security researcher Shaked Chen wrote in a report shared with The Hacker News. "It was a living operation with real-time operator panels, advanced evasion, continuous evolution and a criminal-commercial loop that quietly feeds on the same accounts it helps steal back." The findings are just the latest example of how Vietnamese threat actors continue to embrace various tactics to gain unauthorized access to victims' Facebook accounts, which are then sold...

Cybersecurity researchers are warning of two cybercrime groups that are carrying out "rapid, high-impact attacks" operating almost within the confines of SaaS environments, while leaving minimal traces of their actions. The clusters, Cordial Spider (aka BlackFile, CL-CRI-1116, O-UNC-045, and UNC6671) and Snarky Spider (aka O-UNC-025 and UNC6661), have been attributed to high-speed data theft and extortion campaigns that share a remarkable degree of operational similarities. Both hacking groups are assessed to be active since at least October 2025, with the latter a native English-speaking crew sharing ties to the e-crime ecosystem known as The Com . "In most cases, these adversaries use voice phishing (vishing) to direct targeted users to malicious, SSO-themed adversary-in-the-middle (AiTM) pages, where they capture authentication data and pivot directly into SSO-integrated SaaS applications," CrowdStrike's Counter Adversary Operations said in a report. ...

Cybersecurity researchers have disclosed details of a new China-aligned espionage campaign targeting government and defense sectors across South, East, and Southeast Asia, along with one European government belonging to NATO. Trend Micro has attributed the activity to a threat activity cluster it tracks under the temporary designation SHADOW-EARTH-053 . The adversarial collective is assessed to be active since at least December 2024, while sharing some level of network overlap with CL-STA-0049, Earth Alux, and REF7707 . "The group exploits N-day vulnerabilities in internet-facing Microsoft Exchange and Internet Information Services (IIS) servers (e.g., ProxyLogon chain), then deploys web shells ( Godzilla ) for persistent access and stages ShadowPad implants via DLL sideloading of legitimate signed executables," security researchers Daniel Lunghi and Lucas Silva said in an analysis. Targets of the campaigns include Pakistan, Thailand, Malaysia, India, Myanmar, Sri Lank...

Cybersecurity researchers have disclosed details of a stealthy Python-based backdoor framework called DEEP#DOOR that comes with capabilities to establish persistent access and harvest a wide range of sensitive information from compromised hosts. "The intrusion chain begins with execution of a batch script ('install_obf.bat') that disables Windows security controls, dynamically extracts an embedded Python payload ('svc.py'), and establishes persistence through multiple mechanisms including Startup folder scripts, registry Run keys, scheduled tasks, and optional WMI subscriptions," Securonix researchers Akshay Gaikwad, Shikha Sangwan, and Aaron Beardslee said in a report shared with The Hacker News. It's assessed that the batch script is distributed via traditional approaches like phishing. It's currently not known how widespread attacks distributing the malware are, and if any of those infections have been successful. "Based on our current a...

Intro A sophisticated, high-resilience malicious campaign was identified by Atos Threat Research Center (TRC) in March 2026. This operation specifically targets the high-privilege professional accounts of enterprise administrators, DevOps engineers, and security analysts by impersonating administrative utilities they rely on for daily operations.
