[Wayback/Archive] Fraudehelpdesk ontvangt groot aantal meldingen over fraudetelefoontjes – Security.NL

Ik had zelf al gemerkt dat de hoeveelheid SPAM calls enorm was toegenomen: 2025 first quarter (our winter): a set back in energy, slowly getting back, taking preventions to keep this from happening again

Kennelijk ben ik niet alleen hierin.

i-am-shodan/USBArmyKnife: USB Army Knife – the ultimate close access tool for penetration testers and red teamers.

Posted by jpluimers on 2025/09/30

Now that I got pointed to this twice (see “Via” below), I need to get one so I can play with it: [Wayback/Archive] GitHub – i-am-shodan/USBArmyKnife: USB Army Knife – the ultimate close access tool for penetration testers and red teamers.

vx-underground (@vxunderground) / Twitter

Posted by jpluimers on 2025/09/09

I thought I had been living under a stone for decades when I bumped into vx-underground (@vxunderground) / Twitter

The largest collection of malware source code, samples, and papers on the internet.

Password: infected

That appeared to be untrue as vx-underground, ran by a team of volunteers, started in 2019 ([Archive] web.archive.org/web//vx-underground.org) right when a few crisis in my life came together at the same time.

So here are the links for my archive as they are great content for both Red Teams and Blue Teams on many things cyber security related:

In case I need a small 5-port managed switch that can do port-mirroring: GS305E | Easy Smart Managed Essentials Switch | NETGEAR Support

Posted by jpluimers on 2025/08/13

[Wayback/Archive] GS305E | Easy Smart Managed Essentials Switch | NETGEAR Support which can do many-to-one port mirroring.

This is a newer and cheaper hardware revision than the:

  • GS105Ev2 (which is managed and can do port-mirroring, and is confusingly sold as GS105E-200) which in Germany already is end-of-life
  • GS105Ev1 (which is unmanaged and cannot do port-mirroring and is confusingly sold as GS105E-100) which is end-of-life but still sold

Via [Wayback/Archive] Everyone Should Have One of These – EASY Packet Capture! – YouTube who explains very well why you need a switch that can do port-mirroring, then recommends the GS105E but forgets to mention:

  • there are different revisions of the GS105E with the above drawbacks
  • there is GS305E

html – What can cause Chrome to give an net::ERR_FAILED on cached content against a server on localhost? – Stack Overflow

Posted by jpluimers on 2025/08/07

On my research list [Wayback/Archive] html – What can cause Chrome to give an net::ERR_FAILED on cached content against a server on localhost? – Stack Overflow

The reason what that back then this would fail (but worked in Firefox and Safari, and because I was in a hurry I didn’t research further): [Wayback/Archive] https://www.office.com/

This site can’t be reached

The webpage at https://www.office.com/ might be temporarily down or it may have moved permanently to a new web address.

ERR_FAILED

Thanks [Wayback/Archive] Mason Wheeler and [Wayback/Archive] Joel Davey.

VISA payments needed JavaScript enabled for https://secure5.arcot.com/

Posted by jpluimers on 2025/07/04

While paying with VISA card for some services, I had to explicitly enable JavaScript for the https://secure5.arcot.com/ domain which looks suspicious and is titled [Wayback/Archive] location.hostname

Screenshot: This is Arcot Secure Services This is the Arcot OBO verified by visa service Please visit visa website for more details

Before I enabled JavaScript for it, I did some querying around as at first it looked like a man-in-the-middle-attack. I wasn’t the only one, as this was going on since 2013 (but I didn’t notice it earlier as I only disabled JavaScript for most sites in 2022): [Wayback/Archive] Verified by Visa and arcot.com function like a man-in-the middle attack – Jason Pearce (found via [Wayback/Archive] arcot obo – Google Search)

JavaScript there is needed so VISA card can use Arcot to be the intermediate between VISA and the web-site:
