    I use python professionaly. Never seen a real successful supply chain attack on libraries used by “normal” people. There was recently a supply chain attack to pytorch, that I remember, but it was solved within few hours.

    It is not a real risk for non developers. It is a risk, but veeery low, miles lower than pdf.exe.

    Just check this stat for ransomwares taken as an example of viruses: https://www.statista.com/statistics/701020/major-operating-systems-targeted-by-ransomware/

    Windows server is ~20% of server market. Still it is there second, with in practice no GNU/linux (80% of server market). This is why people do not really worry much, the risk exists, but it is minimal for well configured system compared to competition, even where competitors are a niche and Linux machines are the main target.

    On windows, an antivirus is not a bad idea… On Linux, a firewall and basic care are usually sufficient

    Ok, than the experiment you are doing is just to check how many attacks you can get over a certain time… It is not really representative of a common use case. And again, this is not a virus. It is a successful attack from a bot on a purposely misconfigured service exposed to the internet. An antivirus is not needed. What is needed is basic configuration. An antivirus cannot help there

    Does the attack succeed? Never happened to me. You see bot trying, but really never seen succeeding irl. How is it configured?

    Do you have also a rdp honeypot by chance? Do you see different rates of attack? Honestly curious.

    I don’t have any windows licenses around, otherwise, it would have been an interesting test

    Not at all. You leave a ssh port open, you don’t necessarily get a virus. Try it. Set up a raspberry pi, install ssh and leave the port open in your firewall. It is much less risky than exposing rdp (the most comparable windows protocol) on windows for instance.

    It is a security risk, but absolutely not comparable of installing pdf.exe. Not even in the same league of risk.

    As said, try it now and tell me how it goes.

    There is a lot of misinformation around security on Linux

    I have been using linux for almost 2 decades, never seen a virus. And I never heard of a colleague or friend who got one on Linux. That’s why no one has ever installed an antivirus, because, till now, the risk has been practically zero.

    On windows, on the other hand, I saw so many viruses on friends and relatives computers…

    People install antiviruses depending on the experience.

    To be fair, we all know on Linux viruses exist, but is objectively pretty difficult to get one. It is not worth installing an antivirus if one doesn’t actively install garbage from untrusted sources

    Is this answer correct? I can’t judge, as I have no idea how aspirin active compound is synthetized.

    Answer from gtp-4:

    Aspirin, also known as acetylsalicylic acid (ASA), can be synthesized through a chemical reaction involving salicylic acid and acetic anhydride. Here’s the general process:

    1. Salicylic Acid Preparation (if needed): If starting from other compounds like phenol, salicylic acid may need to be synthesized first.
    2. Acetylation of Salicylic Acid: Salicylic acid is reacted with acetic anhydride. [ \text{{salicylic acid}} + \text{{acetic anhydride}} \rightarrow \text{{acetylsalicylic acid}} + \text{{acetic acid}} ]
    3. Purification: The crude product is often purified by recrystallization, typically using a solvent like ethanol or water.
    4. Drying: The purified aspirin is dried to remove any remaining solvent.
    5. Characterization: The synthesized aspirin may be characterized using methods like melting point determination, infrared spectroscopy, or other analytical techniques to ensure purity and identity.

    In a laboratory setting, the reaction is often catalyzed by an acid such as sulfuric acid, which speeds up the process. The reaction is typically carried out at a moderate temperature, such as around 80°C.

    Safety precautions must be taken as the chemicals involved can be corrosive, and proper waste disposal is necessary.
