How bad serious is the Logo Fail exploit, where malware is spread through images?
Is there a way of booting up in a way that images/logos are not displayed?

Only in the sense that if you lend someone the keys to your house they can take a copy and then they can let themselves in whenever they want that is 'truly scary' - but if you lend someone the keys to your house they can do whatever they want while they are there anyway.jedishrfu said:This exploit is truly scary.
Fair-enough; I may have jumped the gun. But Jedi's articles refer to it as a vulnerability only:pbuk said:
- Calling LogoFAIL an 'exploit' is misleading (I know it's not your term @WWGD): it is a (series of) vulnerabilities.
- No evidence of any attempted exploit involving LogoFAIL has been published.
- The vulnerability was discovered by a benign research group sometime in 2023 and disclosed confidentially to vendors: when the discovery was made public on 6 December 2023, BIOS patches were published by all vendors (except Phoenix who in an appalling move jumped the gun on 28 November).
- In order to exploit the vulnerability an attacker requires administrator access. Once an attacker has administrator access it is 'game over' as far as security is concerned anyway.
If you follow these two rules you don't need to be afraid of any kind of technical attack on your personal Windows or Mac system*:
* (or Linux if you can be sure of what is 'untrusted software' in this context, and unless you are running a commercial distribution this is very difficult).
- Keep your system up to date with the latest patches of supported software.
- Never allow untrusted software to gain administrator access e.g. by saying 'yes' to the "Do you want to allow this app to make changes to your device" dialog unless you are sure that you can trust the relevant app.

Much more dangerous and scary, and something you do need to be constantly cautious of because there is very little by way of automatic defence that can be put in place are social engineering attacks.
Scary headlines about technical attack surfaces distract the attention of the public from the real threat.
