Risk assessment is, of course, subjective, but I wouldn't worry too much if you're behind a firewall, or a router with NAT and no ports forwarded to this Mac. In that case, the only danger comes from actions originating at your machine, either done by you or the OS -- which is mostly software you download and run, websites you open, that sort of thing. And ...

This document from the NSA, NSA/CSS Storage Sanitization Manual: Purpose and Scope, even though from 2014, is a good summary of how governments have been doing secure destruction of media for a long time: note that all the methods are very old-school! Other government agencies, both in the US and internationally, likely use very similar methods. As far as I ...

Econet did not; there was no authentication at the network level. Nor could you attach a floppy drive directly to Econet; you'd use a computer (BBC, Master or Archimedes) that had a floppy or (later) hard disk drive attached, running server software, or an Acorn FileStore unit. Some versions of the server software did implment authentication and permissions. ...

The term you are looking for is van Eck phreaking - the use of electromagnetic radiation produced by computing equipment. To spy on the display, you receive and demodulate the radiation from CRT monitors, produced by repeating electron beam pulses. It was perhaps easier to eavesdrop on (UHF) radiation from the computer modulator in the gold era of 8-bit ...

I believe it's because that version of Internet Explorer does not support Server Name Indication, which is part of the TLS protocol which allows a secure handshake to be established when multiple domains with different certificates are hosted at the same IP. If badssl.com is hosted on shared hosting, then I think this explains your issue. On Webmasters Stack ...

Additionally you had full read/write and execute access on any other station's RAM (including video RAM) if you used assembly language. This is without any authentication required, so there was no security in that aspect.

Computer displays, and the cables that feed them, emit electromagnetic radiation (radio- and TV-frequency radio signals). With a directional antenna and a sensitive receiver, these can be picked up, and used to drive an eavesdropping display. This is known as TEMPEST or Van Eck Phreaking. Countermeasures include physical shielding (tinfoil is actually ...
