2026 Cybersecurity Assessment: The Gap Between Awareness and Resilience

2026 Cybersecurity Assessment: The Gap Between Awareness and Resilience

7月 01, 2026 Attack Surface / Artificial Intelligence
Organizations have never had greater awareness of cyber risk. Yet turning that awareness into operational resilience has never been more challenging. The 2026 Bitdefender Cybersecurity Assessment confirms this is the case, as this year's findings reveal a series of surprising contradictions. Here are a few examples, based on the independent survey of 1,200 IT and cybersecurity professionals across six countries. IT & security leaders believe they have sufficient visibility into employee AI usage, while many frontline practitioners disagree .  Security teams understand the importance of reducing the attack surface, yet they often lack the skills, resources, or strategy to do so.  AI dominates cybersecurity conversations, but in some cases, it is drawing attention away from more prevalent attack techniques already causing significant damage.  Although organizations say they recognize the importance of transparency after a breach, many professionals st...
Phantom Squatting Uses AI-Hallucinated Domains for Phishing and Malware

Phantom Squatting Uses AI-Hallucinated Domains for Phishing and Malware

7月 01, 2026 Artificial Intelligence / Threat Intelligence
Large language models keep inventing web addresses that do not exist. Attackers have started buying those made-up domains before anyone else can, then hosting phishing pages on them to catch traffic that AI tools point their way. Palo Alto Networks' Unit 42 calls the trick phantom squatting , and its new research shows it is already happening in the wild. The reason it matters is trust. Developers and AI assistants increasingly treat the links a model hands back as real. When a model invents a domain that does not exist yet, whoever registers it first inherits all of that misplaced trust, with no phishing email and no malicious ad required. To measure the problem, Unit 42 asked two AI models 685,339 questions about 913 well-known brands across technology, finance, healthcare, government, gambling, and other sectors. The models produced 2.1 million links. Threat intelligence already flagged 13,229 of them as outright malicious, meaning the AI was handing out known-ba...
Researcher Analyzes 3,000 Live ClickFix Payloads, Exposing API-Driven Malware Delivery

Researcher Analyzes 3,000 Live ClickFix Payloads, Exposing API-Driven Malware Delivery

7月 01, 2026 Threat Intelligence / Social Engineering
ClickFix , the trick that fools people into running malware by hand, has quietly grown a back office. New research shows the malicious commands behind its fake "prove you're human" pages are now handed out by API-driven servers that give each visitor the same malware in a different disguise. The same research also turned up a new delivery method built to slip past Windows' script scanning. Security researcher Bert-Jan Pals took apart several ClickFix platforms and analyzed roughly 3,000 payloads from live campaigns. He presented the findings at  OrangeCon  in early June and  published the details  on June 30. ClickFix is simple by design. A booby-trapped page shows a fake CAPTCHA or error, hidden JavaScript drops a command into your clipboard, and the page tells you to press a key combo, paste, and hit Enter. You run the malware yourself. There's usually no exploit at the first step and often no file for traditional antivirus to flag, so conventional emai...

RustDuck Botnet Rebuilds in Rust to Hijack Routers and Servers for DDoS

RustDuck Botnet Rebuilds in Rust to Hijack Routers and Servers for DDoS

6月 30, 2026 Botnet / Vulnerability
A new two-stage malware family called RustDuck is hijacking home routers, IP cameras, Android boxes, and poorly secured servers, then stitching them into a network built to knock websites and online services offline. Researchers at QiAnXin's XLab have tracked it since February 2026, and say the real story is not how big it is today, but how fast it is changing. The end goal is a distributed denial-of-service (DDoS) attack: flooding a target with junk traffic from the infected machines until it buckles. RustDuck is one more entrant in a crowded field, but it stands out for two reasons. It is being rewritten from the C programming language into Rust, and its newer versions go to unusual lengths to avoid being studied or shut down. How it spreads RustDuck does not lean on a single clever trick. It sprays a mix of old, well-known weaknesses and hopes one sticks. The first is the oldest in the book: devices left on the internet with weak or default passwords on their rem...
Langflow RCE Exploited to Deploy Monero Miner on Exposed AI App Endpoints

Langflow RCE Exploited to Deploy Monero Miner on Exposed AI App Endpoints

6月 30, 2026 Vulnerability / Malware
Threat actors are continuing to exploit a critical Langflow vulnerability as part of fresh attacks designed to deliver a Monero cryptocurrency miner. The activity has been found to weaponize CVE-2026-33017 (CVSS score: 9.3), an unauthenticated remote code execution (RCE) vulnerability in Langflow, indicating threat actors are scanning and targeting exposed artificial intelligence (AI) application endpoints for obtaining initial access to enterprise networks. The attack was observed over a 19-day window between March 27 and April 15, 2026. "In this campaign, a single line of Python code evaluated inside an unauthenticated Langflow API endpoint pulls down a shell script, fetches a miner binary, and launches it detached," Trend Micro researchers Simon Dulude and John Zhang said in a technical report published last week. At a high level, the malware is designed to terminate competing cryptocurrency miner processes associated with Kinsing , WatchDog , Rocke , and Outlaw ,...
Malicious Perplexity Chrome Extension Intercepted Searches and Address Bar Input

Malicious Perplexity Chrome Extension Intercepted Searches and Address Bar Input

6月 29, 2026 Browser Security / Web Security
Microsoft has found a malicious Chrome extension that posed as the AI search engine Perplexity and quietly logged what people searched for. It routed every query and every character typed into the address bar through an attacker-controlled server before redirecting users to real results. Microsoft says Google removed it from the store after responsible disclosure. The extension was called "Search for perplexity ai" (ID flkebkiofojicogddingbdmcmkpbplcd) and used a look-alike domain, perplexity-ai[.]online, to pass for the real service at perplexity.ai. Microsoft's Defender research team  says the point was to intercept searches and collect data. It found no proof of password theft, but far more access than a search box should ever need. Once installed, the extension sets itself as the browser's default search engine. When you searched, the query went first to perplexity-ai[.]online, where the attacker's server logged it with your browser headers, IP address,...
Mustang Panda Uses Zoho WorkDrive as Command Channel in Indian Government Attacks

Mustang Panda Uses Zoho WorkDrive as Command Channel in Indian Government Attacks

6月 29, 2026 Threat Intelligence / Malware
The China-aligned espionage group  Mustang Panda  is running two campaigns against the Indian government and hydropower targets, deploying new malware and turning a legitimate cloud service into its command channel. Acronis Threat Research Unit  found active compromises inside Indian government networks, including machines used by senior administrative staff, and worked with  CERT-In  on notification and cleanup. The malware abuses  Zoho WorkDrive , a cloud storage platform common in India's government sector, to pass commands and exfiltrate data. That is the whole idea: the traffic looks like ordinary cloud activity, so it hides inside the network it is stealing from. Acronis names three new tools. SHARDLOADER is a loader that runs by sideloading a malicious DLL through a legitimately signed binary, a Solid PDF Creator executable in one campaign, and a Citrix Receiver binary in the other. It deploys one of two implants. MINIRECON is a rewor...

"This poses the highest risk to multi-te...
Gamaredon Expands Ukraine Attacks with New Malware and Cloud Service Abuse

Gamaredon Expands Ukraine Attacks with New Malware and Cloud Service Abuse

6月 29, 2026 Cloud Security / Malware
A Russian advanced persistent threat (APT) group has continued to evolve and expand its malware arsenal as part of its ongoing cyber onslaught against Ukraine throughout 2025. Slovakian cybersecurity company ESET said it observed 35 distinct spear-phishing campaigns mounted by Gamaredon against new targets, with most of them taking place in the second half of the year. Primary targets of these efforts include Ukrainian governmental and military institutions. "Throughout 2025, Gamaredon stayed highly active and remained focused solely on Ukraine," ESET said . "The group's ultimate goal continues to be the exfiltration of sensitive information and other critical data that could be exploited to support Russian interests in the ongoing war in Ukraine." The spear-phishing campaigns make use of archive attachments or XHTML files that employ HTML smuggling to deliver malicious HTA downloaders that are responsible for dropping additional payloads, such as PteroS...
Hijacked npm and Go Packages Use VS Code Tasks to Deploy Python Infostealer

Hijacked npm and Go Packages Use VS Code Tasks to Deploy Python Infostealer

6月 29, 2026 Supply Chain Attack / Cryptocurrency
Cybersecurity researchers have uncovered two hijacked npm packages and a cluster of Go packages that are designed to deploy a Python-based information stealer on compromised Windows, Linux, and macOS hosts. "This attack avoids the most common npm execution paths through lifecycle scripts, perhaps in an attempt to remain 'compatible' with npm v12's security hardenings ," JFrog said in a technical analysis. "The package hides execution inside a VS Code task, configured to run automatically when the project folder is opened in VS Code. From there, the malware retrieves encrypted JavaScript from blockchain transaction data, connects to attacker-controlled infrastructure, launches a socket.io backdoor, and eventually deploys a Python infostealer. The names of the identified npm packages are listed below - html-to-gutenberg fetch-page-assets (which lists html-to-gutenberg as a dependency) The two packages were uploaded to npm on May 25, 2026, an...
New SharkLoader Malware Deploys Cobalt Strike in StrikeShark Cyberattacks

New SharkLoader Malware Deploys Cobalt Strike in StrikeShark Cyberattacks

6月 26, 2026 Malware / Windows Security
A newly discovered cyber attack campaign has been observed delivering a previously undocumented malware family called SharkLoader that acts as a loader for deploying Cobalt Strike Beacon on compromised hosts. Kaspersky, which is tracking the activity under the moniker StrikeShark , said the campaign has targeted a diplomatic organization in Indonesia, government organizations in Taiwan, software development companies across multiple countries, and entities associated with other sectors located in Hong Kong, Lebanon, Syria, Colombia, North Macedonia, Nepal, and Serbia.  "The observed victimology suggests a campaign with broad geographic reach and a diverse target set rather than a narrow focus on a specific industry or region," the Russian cybersecurity vendor said . The campaign does not exhibit direct links to any known threat actor or group, although the operators have utilized several open-source post-compromise tools like FScan and Pillager , which are commonly p...
Chinese-Speaking APT Deploys New TinyRCT Backdoor in Southeast Asia Campaign

Chinese-Speaking APT Deploys New TinyRCT Backdoor in Southeast Asia Campaign

6月 26, 2026 Cyber Espionage / Malware
A Chinese-speaking advanced persistent threat (APT) actor has been linked to a new custom backdoor called TinyRCT as part of cyber attacks aimed at government entities and critical infrastructure in Southeast Asia. The activity, particularly aimed at state-owned enterprises in the energy and government sectors, has been attributed to a threat actor called CL-STA-1062 , which Palo Alto Networks Unit 42 said shares overlaps with UAT-7237 , a hacking group that was first flagged by Cisco Talos in August 2025 in relation to a campaign directed against web infrastructure entities in Taiwan. Unit 42 said it also observed CL-STA-1062 campaigns in prior operations targeting strategic sectors in East Asia since March 2022, suggesting a broader but sustained focus in the region. "From a technical standpoint, the attackers behind CL-STA-1062 rely on a hybrid toolkit," Unit 42 said in a technical report. "While they frequently use common open-source tools such as SoftEther ...

Miasma Malware Targets npm Packages and GitHub Actions in Supply Chain Attack

6月 26, 2026 Supply Chain Attack / Developer Security
Cybersecurity researchers have flagged yet another evolution of the supply chain attack linked to the Mini Shai-Hulud, Miasma, and Hades malware family that has compromised a new set of npm packages, even as it has propagated to the Go ecosystem. "The latest activity includes malicious npm releases affecting LeoPlatform and RStreams packages, GitHub Actions workflow abuse, and a related Go module compromise involving the Verana Blockchain project," Socket said . The end goal of the campaign, as before, is to harvest developer or maintainer credentials and weaponize the stolen data to spread across package registries, repositories, and trusted developer workflows. The list of affected packages is below - hexo-deployer-wrangler@1.0.4 hexo-shoka-swiper@0.1.10 leo-auth@4.0.6 leo-aws@2.0.4 leo-cache@1.0.2 leo-cdk-lib@0.0.2 leo-cli@3.0.3 leo-config@1.1.1 leo-connector-elasticsearch@2.0.6 leo-connector-mongo@3.0.8 leo-connector-mysql@3.0.3 ...
Microsoft Warns of Photo ZIP Phishing Campaign Targeting Hotels with Node.js Implant

Microsoft Warns of Photo ZIP Phishing Campaign Targeting Hotels with Node.js Implant

6月 26, 2026 Phishing / Malware
An active phishing campaign has been targeting hotel and other hospitality organizations across Europe and Asia since April 2026, using photo-themed ZIP files to drop a Node.js implant and dig into front-desk machines, Microsoft says. The company has not attributed the activity to a known threat actor, and the operators' end goal is still unclear. The lure plays to how hotels work. Phishing emails carry the display name "Booking Manager (via Calendly)" and reference guest complaints, bedbug infestations, room inquiries, health inspections, and stay reviews. The lures came in Japanese, Danish, and Dutch, with Japanese the most common. The subject line names no recipient or property, which points to high-volume, list-driven sending rather than tailored spear phishing. The pressure is reputational: complaints, final warnings, threatened inspections. The delivery is the interesting part. The operators route messages through Calendly's email notification system a...
Google Details Turla's New STOCKSTAY Backdoor Used in Ukraine Espionage Attacks

Google Details Turla's New STOCKSTAY Backdoor Used in Ukraine Espionage Attacks

6月 26, 2026 Cyber Espionage / Malware
The Russian state-sponsored threat actor known as Turla has been attributed to a previously undocumented .NET backdoor called STOCKSTAY that has been deployed against government and military organizations in Ukraine, and entities that have an interest in Italian foreign policy. Describing the Windows backdoor as continually developed by the hacking group, Google Threat Intelligence Group (GTIG) said the cyber espionage tool shares significant code and functional overlaps with Kazuar , a staple implant put to use by the adversary since 2017. Suspected development activity of malware dates back to December 2022. "STOCKSTAY is a multi-component backdoor written in .NET, using the Windows Forms framework, which communicates with its command-and-control (C2) via a secure WebSocket connection, utilizing the open-source websocket-sharp library," GTIG said . "STOCKSTAY consists of several distinct components that communicate with one another via an inter-process commu...

Chrome Ad Blocker with 10M+ Installs Found with Dormant Script Injection Capability

6月 25, 2026 Browser Security / Malware
An analysis of a popular Google Chrome ad block extension for YouTube has uncovered the ability to execute arbitrary JavaScript code. According to Island, the extension, named Adblock for YouTube , has more than 10 million installs and carries a Featured badge on the Chrome Web Store. The extension (ID: cmedhionkhpnakcndndgjdbohmhepckk ) description states that it allows users to prevent web page elements like ads, including preroll ads, from being displayed on the video sharing platform, as well as on external sites that load YouTube. While the add-on offers the promised functionality, it also features capabilities to run arbitrary JavaScript code. "It also contains the architectural ingredients for arbitrary JavaScript execution on any website, activated by a single server-side configuration change, without an extension update, without a store review, and without any visible sign that something has changed," researchers Oleg Zaytsev and Shachar Gritzman said in a re...

6月 25, 2026 Hacking News / Cybersecurity News
It’s dumb out there again. This week has the usual smell of prod on fire and nobody wanting to admit who left the door open — old creds still working, trusted apps doing sketchy crap, browser tricks jumping the fence, and “normal” workflows turning into phishing pipes because apparently email was not enough hell already. The worst part is how cheap some of it feels. Not elite. Not cinematic. Just stale secrets, fake updates, lazy trust, and random boxes quietly becoming someone else’s infrastructure. Same internet, fresh headache. Let’s get into it.
New Gaslight macOS Malware Uses Prompt Injection to Disrupt AI-Assisted Analysis

New Gaslight macOS Malware Uses Prompt Injection to Disrupt AI-Assisted Analysis

6月 25, 2026 AI Security / Malware
A previously undocumented Rust-based macOS implant and information stealer has been found to embed a prompt injection payload designed to trick a malware analyst's artificial intelligence (AI) tools and trick it into aborting or refusing an analysis of the artifact. The malware has been codenamed Gaslight owing to this deceptive behavior. It's been assessed with high confidence that the tool is the work of North Korea-aligned threat actors. "Its most notable feature is an embedded cascade of fabricated system-failure messages, designed to make an LLM-assisted triage agent doubt its own session," SentinelOne researcher Phil Stokes said in a technical report. "It attacks the agent's perception, rather than the sandbox it runs in." Central to the malware's architecture is a Telegram bot API based command-and-control (C2) channel that enters into a polling loop, allowing the operator to issue instructions over an interactive shell and return the...
New Mistic Backdoor Linked to KongTuke in ClickFix and ModeloRAT Campaigns

New Mistic Backdoor Linked to KongTuke in ClickFix and ModeloRAT Campaigns

6月 25, 2026 Initial Access Broker / Ransomware
A new, stealthy backdoor named Mistic has been deployed as part of suspected financially motivated attacks aimed at multiple organizations spanning insurance, education, IT, and professional services sectors since April 2026. According to Symantec and Carbon Black's Threat Hunter Team, the backdoor, also tracked as MLTBackdoor, is said to be linked to an initial access broker (IAB) named KongTuke (aka 404 TDS, Chaya_002, LandUpdate808, TAG-124, and Woodgnat), and dropped along with ModeloRAT, a Python remote access trojan (RAT) previously attributed to the group. "The backdoor runs payloads in memory with no file written to disk and includes a kill switch that lets it delete itself, which are features consistent with an operator seeking long-term, low-visibility access," Broadcom's cybersecurity teams said in a report shared with The Hacker News. ModeloRAT was first flagged by Huntress in January 2026 in connection with a variant of a ClickFix campaign dub...

CISA Warns Critical Lantronix EDS5000 Flaw Is Being Actively Exploited

6月 24, 2026 Vulnerability / Network Security
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday warned of active exploitation of a critical security flaw impacting Lantronix EDS5000 Series devices, urging Federal Civilian Executive Branch (FCEB) agencies to apply the fixes by June 26, 2026. The vulnerability in question is CVE-2025-67038 (CVSS score: 9.8), a code injection flaw that could result in the execution of arbitrary commands with elevated privileges. "The HTTP RPC module executes a shell command to write logs when the user's authentication fails," according to the vulnerability's description on CVE.org. "The username is directly concatenated with the command without any sanitization. This allows attackers to inject arbitrary OS commands into the username parameter. Injected commands are executed with root privileges." The security flaw was disclosed by Forescout Research Vedere Labs in April 2026 as part of a broader set of vulnerabilities collectively cod...
