Well this is just FUD. Linux and BSDs are much much less prone to virus |
12 |
infection due to their architecture and default authentication restrictions. |
13 |
Also your average Linux user, well at least your average Linux desktop user is |
14 |
more clued up than the MSWindows equivalent. With the advent of Linux to |
15 |
mobile devices (Android) this statement is no longer true. |

I'm sure some poster in 2003/04 posted in this same list about a MSWindows |
32 |
malware running in Wine. That's indication of good code as far as I'm |
33 |
concerned, because most MSWindows programs that I tried would fall over |
34 |
themselves in Wine! LOL! |

You may have to unzip it first, because a lot of malware is zipped to escape |
47 |
detection from some simpler anti-virus checkers. You can also use dd and pipe |
48 |
it to an antivirus to see if it finds anything known. |

All OS are susceptible to malware, but not all malware are viruses. At least |
51 |
one virus has existed for Linux (in the 90s or early 00s), but it was patched |
52 |
overnight if I remember right. Other than that I don't know of any programs |
53 |
which can be replicated on Linux machines. I think this is because despite |
54 |
Lennart's efforts no two linux OS are exactly the same. So, as the virus is |
55 |
trying to replicate itself it will fall down at the next box it tries to |
56 |
infect. |

58 |
However, rogue add-ons in browsers, increasingly sophisticated JavaScripts, |
59 |
and HTML 5 with all its cross-domain/cross-site-request potential could wreck |
60 |
at least some of your data and steal your information, just as easily as the |
61 |
adjacent MSWindows box. Oh, before I forget, did I mention Java? |
62 |
|
63 |
Linux running on mobile devices is a different category because there is great |
64 |
uniformity of the OS across devices. This is a big target for any malware |
65 |
writers and state actors who value their coding time: |
