We break down how ClickFix works on macOS: why attackers trick users into running commands in Terminal, what data the malware steals, and how to protect your device.
This vulnerability allows local attackers to escape the model runner sandbox on affected installations of Docker Desktop for macOS. An attacker must first obtain the ability to execute low-privileged code within the sandbox in order to exploit this vulnerability. The ZDI has assigned a CVSS rating of 8.8.

ClickLock is a newly identified macOS malware that steals information by forcibly terminating all visible processes, thereby trapping users into re-entering their system login password. This coercive behavior aims to capture the user's credentials. The malware targets macOS systems and is classified as medium severity due to its information-stealing capability. There is no current evidence of exploitation in the wild, and no patches or official remediation guidance have been provided.
The new macOS malware has targeted at least 100 users to steal their passwords and cryptocurrency. The post ‘ClickLock Stealer’ Bypasses macOS Security With Social Engineering, Process Killing appeared first on SecurityWeek .
A new modular macOS information stealer named ClickLock Stealer has been discovered targeting users primarily in Europe, North America, and the Middle East. The malware is likely distributed via ClickFix social engineering pages that trick victims into pasting malicious commands into Terminal. Once executed, it deploys four components: a credential stealer, a Keychain stealer targeting Chrome's encryption key, a comprehensive crypto wallet harvester, and a persistent GSocket-based backdoor. The malware employs an aggressive 'locker' technique, killing all visible applications except password dialogs to force user compliance. It targets data from eight browsers, 31 crypto wallet extensions, seven password managers, desktop wallets, macOS Keychain, and shell history. The campaign has compromised at least 100 victims across 33 countries since May 2026, using compromised WordPress domains and Telegram for command and control and exfiltration.
A newly discovered macOS infostealer, implemented in native C++, impersonates Apple's crash-reporting framework to harvest sensitive data. The malware is distributed through a signed and notarized dropper application that bypasses Gatekeeper, then downloads and installs the payload from attacker infrastructure. The stealer validates victim passwords locally using dscl, unlocks the login keychain, and collects browser credentials, cryptocurrency wallet extensions, password manager data, and keychain material. Collected data is encrypted using AES-GCM before being packaged into hidden ZIP archives and exfiltrated to a command-and-control server. The malware establishes persistence by copying itself to a hidden directory and installing a LaunchAgent. It employs control-flow flattening, encrypted strings, and anti-debugging techniques to resist analysis. The campaign uses GitHub for initial staging and multiple fake collaboration software domains as lures.
CrashStealer is a newly identified macOS malware that masquerades as Apple's crash-reporting tool. It is designed to steal sensitive information including user credentials, keychain data, and cryptocurrency wallets. The malware targets macOS users by exploiting trust in legitimate system tools. There is no indication that this malware exploits a specific software vulnerability. No affected software versions are specified. No known exploits in the wild have been reported at this time. The severity is assessed as medium based on the potential impact of information theft. No official patch or remediation guidance is currently available. Users should exercise caution with unexpected crash-reporting prompts and verify software authenticity.
The updates fix vulnerabilities in WebKit, the kernel, WebRTC, Web Extensions, and other components affecting iPhone, iPad, Mac, and Safari users. The post Apple Patches Dozens of Vulnerabilities Across iOS, macOS, and Safari appeared first on SecurityWeek .
Apple released updates for iOS/iPadOS, macOS, and Safari on Monday. There have been no updates for other Apple operating systems (visionOS, watchOS, tvOS). Usually, Apple updates all products at the same time.
An intrusion was investigated that began with exploitation of CVE-2026-48558, a critical authentication bypass vulnerability in SimpleHelp RMM software. The threat actor obtained unauthorized technician access and deployed two previously undocumented malware samples: TaskWeaver and Djinn Stealer. TaskWeaver is a heavily obfuscated Node.js loader that establishes encrypted communications and delivers additional payloads. Djinn Stealer targets credentials across Windows, macOS, and Linux systems, collecting authentication data for cloud platforms, source control, package registries, AI development assistants, browsers, SSH keys, and cryptocurrency wallets. The attacker leveraged legitimate RMM capabilities to transfer files and execute commands across managed systems. Stolen AI assistant tokens provided extensive access to repositories, databases, and cloud accounts. The intrusion demonstrated how a single authentication bypass in trusted management infrastructure can enable widespread credential theft and p...

A new macOS ClickFix campaign employs fake CAPTCHA pages to deceive users into executing malicious Terminal commands. The attack chain downloads and invisibly mounts a DMG file containing a self-signed information-stealer application bundle. This payload, assessed as belonging to the AMOS (Atomic macOS Stealer) lineage—specifically the Odyssey variant—prompts users for passwords through fake System Preferences dialogs. The stealer harvests extensive data including browser credentials, cryptocurrency wallet information from 13 standalone applications and 201 browser extensions, messaging app data, Apple Notes, Safari cookies, and macOS keychain entries. Exfiltrated data is compressed and sent to two command-and-control servers. The malware establishes persistence via LaunchAgent and trojanizes legitimate cryptocurrency applications including Ledger Live and Trezor Suite, replacing them with compromised versions downloaded from attacker infrastructure.

A sophisticated Rust-based macOS implant named macOS.Gaslight has been discovered, featuring a novel 3.5 KB prompt-injection payload containing 38 fabricated system messages designed to disrupt LLM-assisted malware analysis. The backdoor communicates via Telegram Bot API with AES-GCM encrypted payloads over certificate-pinned TLS and includes self-redaction capabilities to hide its bot token from logs. It provides operators with an interactive shell, system information collection, and credential stealing capabilities through a bundled Python script that targets browser data, keychains, and command histories. The implant uses runtime-fetched CPython interpreters and establishes persistence through a LaunchAgent masquerading as an Apple system service. This threat is assessed with high confidence to be aligned with DPRK activity and represents a significant evolution in adversarial techniques targeting security analysts rather than sandbox environments.

A financially-motivated cybercrime cluster designated CL-CRI-1089 has launched Operation FlutterBridge, deploying FlutterShell backdoor malware targeting macOS systems through malvertising. Built with the Flutter framework, FlutterShell masquerades as legitimate applications including podcast players and PDF viewers, delivering adware with full backdoor capabilities such as shell command execution and file system manipulation. The malware uses a WebView-based architecture with JavaScript-to-native bridge, allowing attackers to dynamically modify behavior without recompiling. Distribution occurs through hundreds of Google-verified advertisements controlled by shell companies including AdsParkPro LTD and Advantage Web Marketing LLC. The campaign primarily targets Anglophone and Western European markets. All samples were signed with valid Apple Developer IDs and successfully passed notarization, achieving zero detections on VirusTotal initially. The malware hijacks Google Chrome browsers, redirecting traffic ...
