Sixteen typosquatted RubyGems packages steal browser logins and crypto wallets

Researchers flagged a typosquatting campaign, tracked as StubMaker, that planted sixteen malicious packages on RubyGems to deliver a Windows information stealer. The packages imitate popular Ruby dependencies with clumsy misspellings, betting that a developer will mistype a name during installation. Once installed, the malware harvests browser credentials, cryptocurrency wallets and seed phrases, and Telegram data from the developer's machine. The campaign's name refers to its trick of faking a build toolchain so a malicious install looks like a routine one. It is the latest reminder that open-source package registries remain an easy delivery route for stealers aimed at developers.

Check
Double-check RubyGems dependency names before installing, watch for clumsy misspellings of popular gems, and scan developer machines and CI for the malicious packages if you use Ruby.
Affected
Ruby developers who mistype or fail to verify gem names during installation; the malicious packages install a Windows stealer that takes browser logins, cryptocurrency wallets and seed phrases, and Telegram data.
Fix
Pin and verify dependency names and sources, use lockfiles, prefer tooling that flags typosquats, rotate credentials and wallets on any machine that installed a bad gem, and keep wallets off dev machines.

AmnesiaStealer hijacks live macOS browser sessions to ride past logins

Jamf detailed a new macOS information stealer, AmnesiaStealer, spread through ClickFix lures that trick users into running a command from a fake download page. Beyond harvesting the login password, keychain, browser data, and cryptocurrency wallets, it includes a module that clones the victim's Chromium browser profile, including its logged-in state, into a hidden browser on the infected Mac and gives the attacker live remote control of it through the browser's debugging protocol. Because the session runs on the victim's own device with their real identifiers, this lets the attacker use authenticated accounts while sidestepping multi-factor authentication. Jamf calls it the first macOS malware to combine profile cloning with live remote browser control.

Check
Warn Mac users never to paste and run commands from a web page or fake download prompt, and treat unexpected browser sessions or new hidden browser processes as a compromise indicator.
Affected
macOS users tricked by ClickFix lures into running the loader; AmnesiaStealer steals credentials and wallets and clones logged-in browser sessions for live remote use, letting attackers bypass multi-factor authentication.
Fix
Block known ClickFix infrastructure, educate users against pasted-command prompts, keep macOS and security tooling current, and monitor for browsers launched in debugging mode and unexpected headless browser activity.

Fake Solidity Pro editor extensions steal crypto wallets and developer keys

Researchers at Yeeth Security flagged malicious Visual Studio Code extensions named Solidity Pro that pose as tools for blockchain developers while stealing wallets and credentials. Early versions quietly fetched an encrypted payload from cloud infrastructure after a delay of up to three days and ran it outside the editor to evade quick checks. Later versions became full information stealers, collecting browser profiles, cryptocurrency wallets and seed phrases, source-control tokens, cloud credentials, API keys, and SSH private keys, then sending them out through a Telegram bot. The extensions were pulled from the Open VSX marketplace, but the project's code repository remained available.

Check
Check developer machines for the Solidity Pro extension and remove it, and rotate wallets, source-control tokens, cloud credentials, API keys, and SSH keys if it was installed.
Affected
Blockchain and other developers who installed a Solidity Pro extension; running with the developer's access, it steals cryptocurrency wallets, seed phrases, and source-control, cloud, and infrastructure credentials, exfiltrating them over Telegram.
Fix
Install editor extensions only from trusted publishers, review what an extension can access, keep wallets off development machines, and monitor developer endpoints for payloads fetched and run outside the editor.

Arch Linux halts package adoptions after infostealer floods the user repository

The Arch Linux project temporarily disabled adoption of packages in its user repository, the AUR, after a wave of malicious takeovers of existing packages. Attackers seized packages through compromised maintainer accounts or by adopting orphaned ones, then shipped a Rust-based infostealer that grabs browser credentials, cryptocurrency wallets, password manager data, cloud and developer secrets, AI service API keys, and SSH keys. It also opens remote command execution over an encrypted Tor channel and spreads to other machines using stolen SSH keys. A researcher tracking the campaign claims more than 200 packages were hit, including some popular ones, though that list is not independently confirmed.

Check
If you use the AUR, review recently installed or updated packages and their maintainers, inspect build files before installing, and rotate SSH keys and secrets if you ran a suspect package.
Affected
Arch Linux users who install from the AUR; a hijacked or adopted package can run a Rust infostealer that harvests developer, cloud, and AI credentials and SSH keys, then self-spreads.
Fix
Read AUR build scripts before installing, prefer well-maintained packages, rotate exposed credentials and SSH keys, watch for outbound Tor connections, and treat orphaned or newly adopted packages with particular caution.

ClickLock macOS malware kills apps in a loop until victims type their password

Group-IB detailed ClickLock, a macOS infostealer that coerces victims into handing over their login password. It arrives when a user is tricked into pasting a command into Terminal from a fake verification page, then shows a fake system dialog asking for the password. If the victim refuses, ClickLock begins killing core apps like Finder, the Dock, and browsers every 210 milliseconds, leaving only a password box on an unusable desktop, while also suppressing security notifications. Once the password is entered, it steals the Keychain, browser credentials, and cryptocurrency wallets and sends them to a Telegram bot. Group-IB counted at least 100 targets across 33 countries, over half in Europe.

Check
Warn Mac users never to paste Terminal commands from a website, and never enter a password to stop apps crashing; a Mac killing its own apps behind a password box is malware.
Affected
Mac users tricked into pasting a command from a fake verification page; ClickLock pressures them into entering their password by killing apps in a loop, then steals Keychain data and crypto wallets.
Fix
Only run Terminal commands you fully understand from trusted sources, treat app-killing loops and unexpected password prompts as attacks, and if infected, change passwords and wallet keys from a clean device.

CrashStealer Mac malware uses an Apple-notarized app to slip past Gatekeeper

Jamf detailed CrashStealer, a macOS infostealer delivered through a signed, Apple-notarized app called Werkbit that passes Gatekeeper, since it carried a valid developer ID before Apple revoked it. Distributed as a disk image and gated behind a meeting PIN so it is served only to targeted visitors, the malware validates the victim's login password locally, then harvests broadly from browsers, cryptocurrency wallets, password managers, and the keychain, encrypting the loot before sending it out. It persists by copying and re-signing itself. There is no zero-click stage: a victim still runs the app and enters their password, but the notarized delivery and careful targeting make it more convincing than typical Mac stealers.

Check
Remind Mac users that notarization does not guarantee an app is safe, to be cautious of apps delivered by disk image behind meeting codes, and to refuse password prompts from unexpected installers.
Affected
Mac users who download and run the notarized Werkbit app and enter their password; CrashStealer then steals browser data, crypto wallets, password-manager contents, and keychain secrets, and reinstalls itself to persist.
Fix
Install apps only from trusted sources, treat unexpected password and disk-image prompts with suspicion, keep macOS and endpoint tools updated to catch known indicators, and monitor for apps copying and re-signing themselves.

Compromised jscrambler npm releases dropped a cross-platform infostealer on install

Attackers used a stolen publishing credential to push malicious versions of the jscrambler npm package that install a Rust infostealer as soon as the package is added to a project. Socket ties five bad versions to the same actor, published over about three hours; the malware ships as native binaries for Windows, macOS, and Linux and sweeps developer machines for cloud credentials, crypto wallets, and password-manager vaults. Because jscrambler is a build-time tool used in development and CI, the stealer runs where deploy tokens, cloud keys, and source code live. Partway through, the dropper moved into the package's main code, so installing with scripts disabled does not stop it.

Check
Check lockfiles, package logs, and CI records for the malicious jscrambler versions installed since July 11, move to a clean release or pin to 8.13.0, and clear affected versions from caches.
Affected
Developers and CI pipelines that installed the malicious jscrambler versions; the infostealer captures AWS, Azure, and Google Cloud credentials, crypto wallets and seed phrases, and password-manager vaults from the build environment.
Fix
Remove the bad versions, rotate every credential exposed in affected developer and CI environments, hunt for temp-directory binaries and hidden persistence, and pin and verify dependencies rather than trusting a maintainer account.

PamStealer Mac malware poses as a clipboard app and verifies passwords through PAM

Jamf Threat Labs found a new macOS infostealer, PamStealer, that impersonates Maccy, a popular open-source clipboard manager, through a fake website. Victims download what looks like a Maccy installer but is a malicious AppleScript that quietly fetches a Rust-based stealer. Its standout trick is how it grabs the login password: it shows a native-looking prompt saying "Maccy wants to make changes" and validates whatever the user types against macOS's own Pluggable Authentication Modules, so it only keeps a confirmed-correct password and avoids the noisy process calls other stealers make. The second stage hides as Finder, encrypts its traffic, and delays its Full Disk Access request to avoid suspicion.

Check
Make sure anyone using the Maccy clipboard manager downloaded it only from maccy.app or its official GitHub, and treat unexpected admin-password prompts and Full Disk Access requests during app installs with suspicion.
Affected
Mac users who install software from fake or unofficial sites; PamStealer poses as the Maccy clipboard app, confirms the login password through macOS PAM, then steals credentials, browser data, and wallet access.
Fix
Install Mac apps only from official sites or the App Store, verify download URLs carefully, deny unexpected password and Full Disk Access prompts, and keep macOS and endpoint tools updated.

Djinn stealer harvests cloud and AI credentials through SimpleHelp RMM flaw

A new information stealer called Djinn is being used to grab cloud and AI service credentials, Dark Reading reports. Attackers deliver it by exploiting CVE-2026-48558, a critical authentication-bypass flaw in the SimpleHelp remote-management tool, then use Djinn to target the credentials that link developer and administrator environments to broader enterprise systems. The focus on cloud and AI secrets reflects where valuable access now lives: API keys and tokens for cloud platforms and AI services can unlock far more than a single machine. Organizations that run SimpleHelp, especially unpatched instances, are the immediate exposure point for this credential theft.

Check
Confirm SimpleHelp servers are patched against CVE-2026-48558, and review developer and admin systems for credential theft and any unexpected use of cloud or AI service API keys and tokens.
Affected
Organizations running SimpleHelp remote-management software vulnerable to CVE-2026-48558; Djinn specifically hunts the cloud and AI service credentials that bridge developer and admin environments to wider enterprise systems.
Fix
Patch SimpleHelp immediately, rotate cloud and AI service credentials that may have been exposed, enforce least privilege and short-lived tokens, and monitor for unusual API key usage.

DPRK macOS malware Gaslight plants fake errors to derail AI-assisted analysis

SentinelOne detailed Gaslight, a Rust-based macOS backdoor and information stealer tied with high confidence to North Korea, whose standout trick targets the analyst rather than the sandbox. The sample embeds a block of 38 fabricated "system" messages, formatted to mimic the prompt scaffolding of an AI triage assistant, that try to make an LLM-assisted analysis tool doubt its session and abort, truncate, or refuse the analysis. Beyond that, Gaslight steals browser data, Keychain secrets, and command history, using a Telegram bot for command and control and self-redacting its bot token from its own output. It is an early example of malware built to weaponize the AI tools now common in reverse engineering.

Check
If you use AI or LLM tools in malware triage, review whether sample contents are passed to the model as trusted input, and check macOS hosts for the Telegram-based persistence described.
Affected
macOS users targeted by this North Korea-linked stealer, and analysts whose AI-assisted triage pipelines can be manipulated when malicious sample text is fed to the model as if it were instructions.
Fix
Treat the contents of analyzed samples as adversarial input, never as instructions, and isolate hostile text from AI models. On endpoints, hunt for the published indicators and suspicious com.apple-style LaunchAgents.
