When you have physical access to a machine, assume it is compromised

When you have physical access to a machine, assume it is compromised.

Sometimes the compromise can be as simple as a HID device access:

Tomato by shibby – upgrade procedure and cfg backup | LinksysInfo.org

Posted by jpluimers on 2020/02/24

Reminder to self: [WayBackTomato by shibby – upgrade procedure and cfg backup | LinksysInfo.org:

I keep a text file with the changes I’ve made after a fresh install and I keep the file updated as I make changes.

Re-configuring the router after that takes a bit of time, but it is not that bad. Toastman’s method (here) noted above as well as the methods described here and here can also be used, but I haven’t tried them.

Which encoding failure did encode “vóór” into “v3/43/4r”? – Stack Overflow

Posted by jpluimers on 2020/02/24

From quite some time ago, but still very relevant as encoding issues keep occurring:

A while ago, I saw the text “v3/43/4r” in a document.I know it comes from “vóór” (the acute accent emphasises in Dutch), and wonder which encoding failure was applied to get this wrong.

Source: [WayBackWhich encoding failure did encode “vóór” into “v3/43/4r”? – Stack Overflow

From the [WayBack] answer by rodrigo:

  • ó: is U+00F3, and occupies the same codepoint (0xF3) in a lot of different encodings (most ISO-8859-* and most western Windows-*).
  • In CP850 the codepint 0xF3 is ¾ (U+00BE), that is the three-quarters character. It is the same in other, less used, codepages (CP775, CP856, CP857, CP858).
  • The ¾ is sometimes transliterated to 3/4 when the character is not directly available.

And there you are! “vóór” -> “v¾¾r” -> “v3/43/4r”.

The first part (ó -> ¾) is the usual corruption of ANSI vs. OEM codepages in the Western Windows versions (in my country ANSI=Windows-1252, OEM=CP850). You can see it easily creating a file with NOTEPAD, writing vóór and dumping it in a command prompt with type.
