Credential Theft | Breaking Cybersecurity News | The Hacker News

Cybersecurity researchers have flagged a new macOS information stealer called CrashStealer that's capable of harvesting sensitive data from compromised systems. Unlike other information stealers that are built on AppleScript droppers or Objective-C-based wrappers, CrashStealer is implemented in native C++, according to Jamf Threat Labs. "It validates the victim's login password locally before harvesting, collects broadly across browsers, cryptocurrency wallets, password managers, and the keychain, encrypts what it collects with AES-GCM before exfiltrating over libcurl, and persists by copying and re-signing itself," security researcher Thijs Xhaflaire said in a report shared with The Hacker News. CrashStealer is said to be distributed by means of a signed and Apple-notarized dropper that's distributed as a disk image file named "Werkbit.app." Because both the disk image and binary are notarized and carry a valid developer ID ("Emil Grigorov...

A new phishing-as-a-service (PhaaS) operation called Forg365 is using a combination of device code phishing , adversary-in-the-middle (AitM) tactics, antibot evasion, artificial intelligence (AI)-assisted lure creation, and post-compromise mailbox operations targeting Microsoft 365 accounts. Distributed via Telegram and costing $400 a month (or $3,800 per year), attack chains leverage phishing lures that make use of legitimate email delivery infrastructure, such as Amazon Simple Email Service (Amazon SES) and Twilio SendGrid, to imitate a redirection chain that blends into regular email traffic before it ends in Forg365-controlled domains. "The panel exposes a mature operator workflow: accounts, links, invitations, OAuth app configuration, redirect links, SVG generation, campaign sending, SMTP profiles, SMTP rotation, AI email generation, token vaulting, account intelligence, keyword alerts, viewer links, and browser-extension support," ZeroBAC said . The email securi...

Cybersecurity researchers have flagged an intrusion in which an unknown threat actor leveraged a vibe-coded PowerShell script for Active Directory (AD) enumeration. "The script looked for the Domain Controller (DC) and mapped users, computers, and domains, before creating a directory and exporting out a number of files, and finally creating AD_Report.html to measure the success of the enumeration attempt," Huntress researchers Jevon Ang and Dray Agha said . The attack chain involved the threat actor establishing Remote Desktop Protocol (RDP) access onto a domain-joined Windows Server with a set of pre-compromised credentials, followed by staging the tools in the "C:\ProgramData\" folder. The incident took place in early June 2026. This included an artificial intelligence (AI)-generated payload to map the Active Directory environment. The assessment is based on various telltale signs, such as the prompt iteration title, placeholder strings, over-engineered cod...

An attacker running a live Microsoft 365 phishing operation left a Python web server listening on a public port with directory listing switched on. The command that did it:  python3 -m http.server 8080 , was still sitting in the readable  .bash_history . From that one lapse, French security firm  Lexfo  lifted the operator's entire toolkit and pivoted through it to two more phishing operators, three campaigns in all. Each ran a custom fork of the open-source Evilginx proxy , cloned from public GitHub. The largest of the three had been running for more than a year, its victims overwhelmingly corporate mailboxes. The three got past MFA in two mechanically different ways, one by proxying the live login , one by abusing a legitimate Microsoft sign-in flow. The two need different defenses, which is the part that matters most if you run Microsoft 365. Directory listing on a working attack server is close to a full confession. The listing exposed phishing conf...

Unknown threat actors compromised the Injective Labs SDK project's GitHub repository and leveraged it to publish a malicious package on the npm registry to steal cryptocurrency wallet private keys and mnemonic seed phrases. The compromised version, @injectivelabs/sdk-ts@1.20.21 , came embedded with fake telemetry functionality that exfiltrated data from cryptocurrency wallets. The version was released on July 8, 2026, but has since been deprecated on the registry. That said, the release artifacts belonging to the compromised version are still available for download from GitHub as of writing. "The malicious functionality was introduced to the project's official GitHub repository through commits submitted by a GitHub account belonging to a developer with an established history of contributions to the repository," Socket said . The software supply chain security firm said the threat actor behind the attack also published version 1.20.21 across 17 additional @inj...

A cybercrime crew left one of its own servers wide open on the internet for three weeks, and it exposed the operation's inner workings: the hacking tools, the activity logs, and target lists naming more than 1.4 million websites. Far fewer were actually broken into, but the exposed files showed researchers how a mass site-hacking operation runs from the inside. The operation, now tracked as WP-SHELLSTORM , is what  SOCRadar  calls a webshell access brokerage: a crew that breaks into sites at scale, plants a hidden backdoor (a "webshell") on each, and packages that access for resale. The strongest activity hit WordPress sites running out-of-date plugins. If you run WordPress or Joomla, the two flaws that mattered most were in the Breeze caching plugin and Joomla's JCE editor; skip to the checklist below if that's you. A forgotten server Two teams dug into the same exposed folder. SOCRadar's threat intelligence team spotted it on June 11, 2026, on a U...

Cybersecurity researchers have flagged a new ransomware family called GodDamn that employs the PoisonX kernel driver to neutralize security software as part of its defense evasion strategy. According to a new report published by the Threat Hunter Team from Symantec, the ransomware was first publicly spotted in the wild on May 21, 2026. It's assessed to be a rebrand of the Beast ransomware, which, in turn, was an enhanced version of Monster , a Delphi-based ransomware that surfaced in March 2022. Broadcom's cybersecurity arm is tracing the developer behind these ransomware families under the moniker Hyadina. In one attack orchestrated by the ransomware operation in early June 2026, the threat actors are said to have leveraged AnyDesk for remote access and used a NirSoft-based credential harvesting toolkit before deploying the ransomware. The exact initial access vector is unknown. The credential harvester is designed to extract sensitive data from common web browsers, W...

A suspected China-aligned threat activity cluster has been observed exploiting Roundcube webmail software belonging to physics and engineering departments of U.S. and Canadian universities as part of a new campaign. The activity involves the exploitation of now-patched, critical security flaws in the open-source email solution, such as CVE-2024-42009 (CVSS score: 9.3), to siphon credentials, followed by either the deployment of a web shell for persistent access or a known post-exploitation tool called VShell . The emerging threat cluster is being tracked by Proofpoint under the moniker UNK_MassTraction . It was first detected in May 2026, specifically focusing on administrators and professors in departments with either national security ties or entities studying astrophysics and particle physics. "The emails targeting university departments used both compromised senders, as well as abused domains vulnerable to spoofing due to lax DMARC policy to send the emails," the ...

Cybersecurity researchers have discovered a previously undocumented modular malware framework codenamed Avalon that's distributed by means of a multi-stage phishing chain capable of bypassing traditional security controls. Avalon combines credential collection, lateral movement, remote access, recovery disruption, and ransomware execution, bringing together diverse functions under one umbrella. The ransomware component has been internally named CrownX.  "The attack began with a spoofed legal document email directing recipients to a password protected archive on Proton Drive," Blackpoint Cyber researchers Nevan Beal and Sam Decker said . "Malicious content was embedded inside an ISO image rather than attached directly, reducing the likelihood of detection at the email layer." Should the email recipient interact with a document-themed Windows Shortcut ("Secure Document CA-283505.pdf.lnk") inside the mounted image, it triggers a staged malware s...

Threat actors with ties to North Korea have been linked to a fresh set of malicious npm packages that masquerade as Rollup polyfill tooling to facilitate remote access and data theft. According to JFrog, the packages "rollup-packages-polyfill-core" and "rollup-runtime-polyfill-core" mimic the legitimate " rollup-plugin-polyfill-node " project, down to the description, repository metadata, and package shape. "The lookalike packages place themselves in the same rollup, polyfill, core, and node naming space, which can look plausible during a quick dependency review," JFrog said in a technical write-up of the campaign. The campaign also involves four other packages, all of which have since been removed from the npm registry - quirky-token react-icon-svgs rollup-plugin-polyfill-connect swift-parse-stream What's noteworthy here is that "rollup-packages-polyfill-core" installs and loads "swift-parse-stream,...

Cybersecurity researchers have flagged a new macOS information stealer called PamStealer that employs a series of clever tricks to infect systems and siphon sensitive data. The stealer, discovered by Jamf Threat Labs, is distributed as a compiled AppleScript (.scpt) file impersonating Maccy, a legitimate open-source clipboard manager. It has been codenamed PamStealer owing to its ability to validate the victim's login password through the macOS Pluggable Authentication Modules ( PAM ) before capturing it. The malware is delivered in two stages: A compiled AppleScript distributed inside a disk image that's designed to download and stage a follow-on payload. The secondary artifact is a Rust-based infostealer capable of credential theft, browser data collection, persistence, and exfiltration. The initial access vector for the malware is a lookalike site ("maccyapp[.]com") that mimics Maccy ("maccy[.]app"). The AppleScript ("Maccy.scpt") pres...

Threat actors associated with the Anubis ransomware operation have been observed exploiting the Citrix Bleed 2 (CVE-2025-5777) vulnerability to obtain initial access. "Although tactics differ between affiliates, common patterns emerged in tradecraft through use of legitimate Remote Management and Monitoring (RMM) tooling, credential access, and hands-on-keyboard procedures used for lateral movement," Arctic Wolf said in a report published this week. "Anubis affiliates repeatedly abused legitimate remote access and administration tools, including ScreenConnect, Zoho Assist, MeshAgent, Remotely, UltraVNC, and Total Software Deployment, to blend in with normal IT activity while maintaining control of victim systems." Anubis is a ransomware-as-a-service (RaaS) group that first emerged in late 2024 as a rebrand of Sphinx ransomware. The ransomware operation was formally announced on the Ransomware and Advanced Malware Protection (RAMP) underground forum in Febr...

The threat actor known as ToddyCat has been attributed to a new malware called Umbrij that's designed to gain surreptitious access to a victim's email correspondence via the Google API. "In this campaign, the attackers focused their attention on corporate email communications hosted on Gmail, targeting access compromise via APIs," Kaspersky said in a detailed report published this week. "Because the Google API relies on the OAuth 2.0 protocol for authorization, applications can use an OAuth token to access requested email resources." The adversary is said to have developed Umbrij to acquire this token and use it to connect to the browser's management console in headless mode via a remote debugging port. Subsequently, a series of requests was issued to obtain an OAuth authorization code, which was then exchanged for an access token to reach the target resources via the API. The technique has been codenamed Shadow Token via Remote Debug (STRD) b...

The recently discovered financially-motivated FortiBleed campaign has been attributed to INC and Lynx ransomware operations, indicating that the verified, stolen credentials were intended for follow-on intrusions. "An operator tied to FortiBleed's infrastructure was found actively working negotiation panels for both groups, tying mass FortiGate credential theft directly to ransomware deployment for the first time," SOCRadar said in a new report published Wednesday. The company said it tracked scanning activity against approximately 11,250 FortiGate portals in more than 150 countries, followed by confirmed admin-level access on 409 targets and successful completion of the full attack chain on 354 of them. In all, at least 12 ransomware deployments have resulted from this access, causing hundreds of endpoints to be encrypted across affected organizations. The large-scale credential-harvesting operation, which came to light last month, involved the threat actors sys...

Attackers are hiding a data-stealing trojan inside fake exploit code aimed at the people who hunt bugs for a living. The malware, called ChocoPoC , travels in Python proof-of-concept (PoC) repositories on GitHub that claim to exploit hot new CVEs. Run one, and it quietly lifts your saved passwords, browser cookies, and files, then hands the attacker a shell on your machine.  YesWeHack and Sekoia  published their joint findings on July 1 and warned that, as of that report, the malware and its servers were still live, so do not run any of these PoCs. The trick is where the code sits. The visible PoC looks clean. The malware hides in a Python package that the PoC pulls in as a dependency, so it slips past a quick code review. How the trap works The bait is time pressure. When a big flaw drops, researchers race to test it and grab community PoCs to move fast. This campaign turns that habit into an infection route. The chain, in plain terms: You clone the repo and r...

An unknown threat actor has been observed exploiting a recently disclosed maximum-severity security flaw in SimpleHelp to deliver two previously unreported malware families, TaskWeaver and Djinn Stealer . The intrusion involves the exploitation of CVE-2026-48558 (CVSS score: 10.0), a critical authentication bypass vulnerability impacting the OpenID Connect (OIDC) flow that an unauthenticated attacker could exploit to obtain a fully authenticated "Technician session by submitting a forged token containing arbitrary identity claims. "TaskWeaver is a heavily obfuscated Node.js loader, delivered as jquery.js and executed through node.exe, that implements an encrypted, reusable payload delivery channel rather than a fixed set of post exploitation commands," Blackpoint Cyber said in an analysis. "The observed second stage payload, Djinn Stealer, targets Windows, macOS, and Linux systems." Djinn Stealer is designed to harvest credentials associated with cloud...

Convince an AI browser that it is playing a game, and it can hand over your login details. That is the finding behind  BioShocking , a technique from security firm LayerX that tricked six AI browsers and assistants into copying a user's credentials and sending them to an attacker. The targets included OpenAI's ChatGPT Atlas, Perplexity's Comet, and Anthropic's Claude browser extension. An AI browser is one that can act for you, not just read pages. Switch it to agent mode, and it can click, type, and reach into the sites you are already signed into. That access is the whole point, and it is also the problem. The trick works because of how these agents read. The web page and your own instructions arrive as a single stream of text. That lets a malicious page slip in commands dressed up as ordinary content or game rules, and the agent cannot reliably tell the difference. Researchers call this  indirect prompt injection . How the trick works

Microsoft has shut down a long-running malicious extension operation on the Edge Add-ons store that hid its payloads inside ordinary image and font files, then woke up days after install to steal credentials and run ad fraud. The company calls it  StegoAd , a mash-up of steganography and adware, and ties 119 extensions to a single threat actor it says has been active since at least 2021. The extensions were the kind people install without a second thought: ad blockers, VPNs, translators, video downloaders. Each one did its job and earned reviews. The malicious code stayed dormant until the extension cleared a stack of evasion checks, which is how it sat in the store for years. Combined, the 119 extensions had an install base of up to 2.6 million users. Microsoft is clear that this is a ceiling, not a victim count. A multi-day delay, server-side validation, and a 10% execution gate on some variants meant the payload never fired for many installs. How many people were actual...

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...

The Security Service of Ukraine (SSU) said it, together with the U.S. Federal Bureau of Investigation (FBI), uncovered a long-running campaign orchestrated by Russian intelligence services to break into the messaging accounts of government officials, military personnel, politicians, and activists in Ukraine, Europe, and the U.S. The systematic cyber attacks aimed at stealing sensitive information from the victims, the agency added. "The goal of these 'hacks' is to gain access to sensitive military, political, and economic information exchanged by users, as well as to steal their personal data," the agency warned in a post shared on Telegram. To pull off the operation, the attackers send SMS messages that masquerade as the messaging platform's support bot and urge users to disclose their account credentials.  The SSU noted that these attacks include not only organizations, officials or public figures, but also personal accounts belonging to Ukrainian nati...
