I've just published an update to the Native Messaging Host for my Download Blocker browser extension. This update gives much improved performance when extracting filenames from zip archives. github.com/SecurityJosh/D…
V1.0.3 of DownloadBlocker contains improvements and new features. This includes Native Messaging Host support, which enables download metadata to be calculated for files not downloaded via HTML Smuggling and in more HTML Smuggled file scenarios. github.com/SecurityJosh/D…
As of version 1.0.2, Download Blocker (chrome.google.com/webstore/detai…) can now extract filenames from .zip files that have been HTML smuggled. #blueteam #htmlsmuggling #html5 #DFIR #infosec #soc
I've just published a blog post which shows how you can use #ifttt to receive email notifications when DownloadBlocker detects / blocks a download. Check it out ⤵ securityjosh.github.io/2022/09/09/HTM… #blueteam #htmlsmuggling
To help investigate HTML Smuggling attacks and other malicious downloads, Download Blocker can now also send the user's hostname and username when a download matches a rule. github.com/SecurityJosh/D…
The latest version of DownloadBlocker (0.2.0) is able to extract metadata (SHA256, macro existence) from HTML smuggled files that use this iframe technique. github.com/SecurityJosh/D…

Looks like #TA570 are using HTML Smuggling as part of their infection chain. My chromium extension can block the download of these smuggled files. github.com/SecurityJosh/D…

I've set up an AWS Lambda function to regularly push the list of domain IOCs (as needed) from KasperskyLab's TinyCheck to a GitHub gist so they can be imported into a Pi-hole block list. gist.githubusercontent.com/SecurityJosh/0… #Pihole #TinyCheck
The latest release of Download Blocker has the ability to detect and block the download of HTML smuggled binary office documents based on the presence of macros. #blueteam #infosec #soc chrome.google.com/webstore/detai…
The latest version of DownloadBlocker (0.1.1) is now available on the Chrome web store. New features include file hash retrieval, an audit mode (for testing) and customisable notification content. github.com/SecurityJosh/D… #htmlsmuggling #blueteam
