Excited to secure the developer endpoint right as everyone is becoming a developer
Feross@feross.bsky.social · 3mo agoToday is a big day for @socket.dev. We raised a $60M Series C at a $1B valuation, led by Thrive Capital. 20,000+ orgs, 1.5M repos protected, 1,000+ supply chain attacks blocked per week. 3/5 FAANG companies are customers. We're just getting started.
. @socket.dev just acquired @secureannex.com, the extension security company built by @johntuckner.me. John is joining Socket. John built Secure Annex as a solo founder into a product that security teams at Reddit, Brave, Torq, and Movable Ink depend on.
Today we're announcing that @secureannex.com has been acquired by @socket.dev! Supply chain security is a deceptively wide problem from open source code to browser extensions. Developers and IT teams can't stop it from impacting their organization alone. secureannex.com/blog/annex-a...
A Chrome extension with 7,000 users and a Google Featured badge was recently sold, weaponized, and pushed a malicious update to that executed code through a hidden pixel. Here's how it worked 👇
LimaCharlie released their Agentic SecOps Workspace recently which runs Claude Code in their UI including MCP servers. It's never been so easy to just say 'look at my detections and research the extensions'. Even though 1Password falls under an unapproved policy, at least it isn't malicious!
As predicted - "oorzc" a developer with extensions totalling 25,000 legitimate installs across 4 extensions looks to have had their Open VSX account compromised and published malicious updates. The worst part is this...

If you've had to listen to me over the last couple months, it's likely you would've hear me say that all of our most important apps will have extensions or plugins for integration. Think we're learning from past mistakes?
A browser extension, PasteReady, was listed for sale last May became malicious after an ownership transfer on December 27th. Many organizations have been impacted by extensions which changed hands. @secureannex.com watches for transfers and warns you in advance! www.linkedin.com/pulse/paster...

Pyrefly - Python Language Tooling by Meta is the 4th most used extension in Open VSX. Be careful downloading the 'Pro' version in Cursor hoping you'll get some extra features, it is published by 'casendsabotnu954' who just joined GitHub the other day. Textbook cloning and staging behavior!
Loving a new detection that identifies code extensions published by new and lightly used GitHub accounts.This time it instantly caught an extension impersonating JFrog which already has over 10k downloads.
Not the "pulling a Rabbit out of a hat" magic trick that most want. This Firefox extension completely changes from a "Simple Label Editor" to a Rabby wallet stealer overnight.
A browser extension with over a million users is poaching the prompts of leading AI chat tools. SimilarWeb loads obfuscated remote configuration to collect the prompts, responses and metadata of your conversations. Your private thoughts are analytics companies gain. secureannex.com/blog/prompt-...
Prompt poaching runs rampant in extensions
Web analytics companies are using browser extensions to monetize your most private thoughts

These code comments are an improvement from: 1. Request malware 2. Download malware 3. Make malware executable 4. Run malware This is the extent of the extension available in the VS Marketplace. Installs a Mythic agent from the C2.
Monitoring a large influx of AI slop extensions that are reposting a marginally refactored but known malicious package. The marketplace listings are packed with emojis and a couple sections of 'features'. This one made the mistake of linking to an already known piece of malware.
Welcome to Antigravity the newest most advanced agentic AI development tool by Google... ... uses Open VSX for extensions and shows malicious listings to users.
Changing how an extension looks in a marketplace doesn't require new code to be pushed. Check out the magic when this "Test Extension" magically turns into a "solidity" extension after being published. Review the full lineage of a marketplace listing using the new date picker in Secure Annex.
Vibed coded malicious extensions are getting out of hand! This 'theme' downloads a malicious zip, unpacks it, and runs it silently with PowerShell.
16 Firefox extensions with the almost the same name, same permhash requesting the most sensitive permission combinations like <all_urls> and cookies. Something being staged?
Glassworm returned in a big way during the holiday. We're tracking 23 code extensions across the VS Marketplace and Open VSX which copy popular extensions, evade filters, manipulate their download counts, and then update with sinister malware. secureannex.com/blog/glasswo...
Glassworm stays prevalent
Glassworm attacks look to take full advantage of the holidays

Unprecedented code extension attacks this week. All are name squatting on popular tools. Only a couple have had malware deployed, many are still staging, few have been removed from marketplaces. There may be more coming. VS Marketplace: iconkieftwo.icon-theme-materiall 1/3
Imagine how useful it would be if the Chrome Web Store showed you users over time. This ad blocker went from 0 to 40,000 users overnight! 🤔
Going to have to reread Hacking: The Art of Exploitation, 2nd Edition by Jon Erickson in order to keep up with the advanced tactics we're starting to see in VS Code extension malware.
Really excited to being supporting crxaminer.tech with some Secure Annex details. Looking forward to more opportunities to get more information on browser extensions out there!

The extension was approved, now what? Are you going back tomorrow to see if it changed? You know they auto update instantly right? Rolling out to Secure Annex - code change alerts. This compares past code with additional context to understand how an extension is changing over time. Catch bad quick!
A brand new unlisted extension with 100,000 users? 41 ratings? Must be really valuable. Nope - completely manipulated stats and it doesn't even contain real code. It exists only to collect your searches and earn Bing Rewards.
We've found code extensions openly call themselves malware in the VS Code marketplace recently and now browser extensions posing as known malicious remote access tools to the Chrome Web Store. What gives?
