Wondering if the takeown/icacls/del trick still work to screw up %windir%\system32 (via Patrick Doyle on Twitter)
Posted by jpluimers on 2026/05/07
A few years back this trick was shown to screw up %windir%\system32 [Wayback/Archive] Patrick Doyle on Twitter: “@SwiftOnSecurity @RoseAreaZero Delete any file in three easy steps: > takeown /F "example.ext" > icacls "example.ext" /grant "%USERNAME%":F > del "example.ext"“.
Like [Wayback/Archive] SwiftOnSecurity (@SwiftOnSecurity) / Twitter (see the long thread further below), I was expecting that Windows would either prevent you from doing this at all, or allow for easy recovery with System File Protection (now Source: Windows File Protection).
That didn’t prevent or recover it back then.
I wonder if that has been changed by now.
From the above Tweet:
Delete any file in three easy steps:> takeown /F "example.ext" > icacls "example.ext" /grant "%USERNAME%":F > del "example.ext"

AbortController is your friend
Posted by jpluimers on 2026/05/06
Cool post [Wayback/Archive] AbortController is your friend starting with
One of my favorite new features of JS is the humble
AbortController, and itsAbortSignal. It enables some new development patterns, which I’ll cover below, but first: the canonical demo.It’s to use
AbortControllerto provide afetch()you can abort early:
It then continues with a series of nice use cases.

bash script for $* loop accept command line with spaces in wildcard file names at DuckDuckGo
Posted by jpluimers on 2026/05/05
Back when I wanted a more universal solution [Wayback/Archive] bash script for $* loop accept command line with spaces in wildcard file names at DuckDuckGo I got into a mess of tips that either did not work at all, or were very convoluted.
As back then I only needed a one-time solution, I just listed the filenames with ls into a text file, did some sed and editing steps, then had each file execute in a separate step. Low tech, non-repeatable when new files appeared, but good enough.
In case I want to go for a more universal solution, below are some links to investigate further. Will likely take me hours, so most of the time this is not worth it. Maybe the subshell plus $IFS (Input Field Separators) is a good start, though it gives me a feeling that in the future it will break something else that was expecting a default $IFS value, as is using while read loop. Both types of solutions feel too convoluted. Same for the array solution below.
I might have just been spoiled with PowerShell piping objects instead of strings having made life so much easier.

Arjen Lentz Crystal Ball Vulnerability Prediction: A Wizard’s Guide to Foreseeing the Unseen: NLUUG voorjaarsconferentie, 7 mei 2026, Arjen Lentz over de echte root cause van veel CVE’s en hoe die te fixen
Posted by jpluimers on 2026/05/04
Ook vandaag even een herinnering aan de NLUUG voorjaarsconferentie 2026 van (komende) donderdag 7 2026 mei in het Van der Valk Hotel Utrecht¹.
Deze keer omdat een goede vriend van me daar spreekt. Arjen Lentz heeft het over A Wizard’s Guide to Foreseeing the Unseen.
Dat klinkt misschien vaag, het concrete resultaat is dat je met analyse van CVE’s veel te weten komt over hun echte root cause. Die blijkt verrassend voorspelbaar, is fixbaar, en kennis daarover is niet alleen nuttig voor adversaries. Het kan jou namelijk helpen bij de development en selectie van wat je zelf gebruikt.

Some Twitter internals after I found GitHub – offish/twitter-broadcast-downloader: Download Twitter broadcasts/lives
Posted by jpluimers on 2026/04/30
Found this while trying to find the source from which I constructed this Bookmarklet which from a Tweet URL returns the JSON metadata which has all the links to media (like images and videos) as it failed for broadcasts:
javascript:{ tweetID = document.location.href.split('/').filter(e => e).slice(-1); url = new URL(`https://cdn.syndication.twimg.com/tweet-result?id=${tweetID}&token=!`); open(url); }
I could not find that back, but did find [Wayback/Archive] GitHub – offish/twitter-broadcast-downloader: Download Twitter broadcasts/lives via these query steps:

Dare Obasanjo: “GitHub … How many other services are painting a far rosier picture than reality on their service status pages?” – mas.to
Posted by jpluimers on 2026/04/30
Last 90 days uptime on 20260427 of the GitHub Platform: 87.25%
Because of two alternative GitHub status pages, a lot of people now realise that GitHub gives a rosier result than the official pages.
April uptime not even had one nine, dropping below 89%.
Which begs this interesting question
