Under US law, is it illegal to write a self propagating computer worm Suppose a person creates a self-propagating computer worm that: does not modify or delete any of the victim's files rather displays a funny message to the user scans other computers and spreads itself and then self destructs without any harm. Would that be a punishable offense? What are the applicable laws in this case? Note that the worm self-propagates from the personal computer of the worm writer, so the writer of the worm does not personally infect the next computer. Note that this question is purely for knowledge/information purposes.
Illegal to write? No. Notwithstanding the First Amendment which would almost certainly make a law prohibiting it illegal, writing such things is an essential part of an IT security professional’s toolkit. You can’t protect against worms if you don’t know how they work. Illegal to distribute on an unauthorised computer? Absolutely. This would be a clear breach of the Computer Fraud and Abuse Act.
Ideas are not protected by copyright, only arrangements of words are protected. If you &quot;rephrase&quot; by only a minor change of wording, leaving much of the wording intact, that is still a copyright infringement unless an exception such as fair use or fair dealing applies (and that seems a bit doubtful in this case). If you &quot;rephrase&quot; so that the wording is quite different, even though the idea is the same, there is probably no infringement. Copying elements of computer code or other IT commands that are essential to making an example work is not infringement. Where there is only one or a very small number of ways to naturally express a fact, copying such expression is not infringement, as facts are not protected by copyright. Adding examples but keeping significant wording unchanged is still likely to be infringement.
No, it is not. Just as it is illegal to steal from a thief, it is illegal to hack a hacker. Criminals are often considered a good target for crimes from a practical standpoint, but crimes against criminals are still prosecuted. As criminals are unlikely to report crimes against them to the authorities (particularly when doing so runs the risk of them being arrested for their crimes), targeting them does tend to result in a lower risk of being caught by the authorities, but if the crime is discovered, it will generally be prosecuted all the same. To that point, two Florida men have recently been arrested and are being prosecuted for stealing millions of dollars in Bitcoins from an illegal, darkweb drug marketplace in 2013, and there is always the more famous case of the two government agents who are in jail for stealing from the Silk Road. In your specific example, if all you did was hand over the information to the FBI, it's less likely that you'd be prosecuted than if you did so for personal gain, but you would be at risk of prosecution for engaging in vigilante computer hacking, yes. Also consider that if your actions happened to interfere with an ongoing investigation or result in the inability to prosecute (say, for the evidence you gathered being tainted and inadmissible by your involvement), you could be charged with crimes such as obstruction of justice or interfering with a police investigation as well.
Of course it is illegal. You are attempting to access somebody's data without their knowledge and certainly without their consent. In the U.K. it is a crime under the Computer Misuse Act 1990, the Police and Justice Act 2006 and the Serious Crimes Act 2015. The clue here should be in the term Serious Crimes. The Human Rights Act, and indeed the ECHR, should never come into it unless it was state sponsored or corporate spying. And even then certain states have given themselves Orwellian totalitarian authority to do as they please.
You can't, in general, know whether a distributor of a work has permission to distribute, or is a pirate site. I verified that they have posted an illegal copy of a work that I created, and I know that I did not grant permission to them (or anyone) to infringe my copyright. Both hosting and downloading works without permission is a violation of copyright law, so both parties are liable. Downloaders may erroneously rely on the "I didn't know!" defense, which in the US carries no legal weight. Even so, if you download my book, it will probably cost me vastly more to sue you for infringement than the damages that I might be awarded over your infringement. Usually, copyright holders go after the pirate sites, and only rarely go after particularly egregious serial downloaders.
Generally, no, this will not violate copyright. Your end user might violate copyright, but that is their problem not yours. Your program is a tool, just like a word processor is. If I copy a Harry Potter book into a word processor that does not make the word processor maker liable. There is a concept of "contributory infringement", which I think is what you are concerned about. I don't know about Danish law in particular, but most countries would require evidence that you had reasonable knowledge that actual copyright violation was occuring, rather than just being aware that it might happen in theory. This is normally applied to file sharing services who have to have "notice and takedown" measures, file filters and the like. This isn't your concern as you never have any access to the files created by your users. You can also be found liable if you induce anyone to commit copyright violations. Don't draw your customers attention to the custom monster feature as a workaround for those copyrighted monsters, as that could be considered to be inducement. Also don't provide any "wizards" or similar tools which make it noticeably easier to duplicate the custom monsters (e.g. if you notice that the copyrighted custom dragon stats are all on a linear scale with dragon size, don't create a "dragon creation wizard" embodying that fact.) This assumes that your program runs entirely on the end user computer. Its different if you provide any kind of cloud storage for generated characters.
The most apparent potential offences would be under 18 U.S.C. § 1030, but these require the mens rea of &quot;knowingly&quot; or &quot;intentionally&quot; doing things without authorization, or doing so &quot;with intent to defraud&quot;, etc. See also the Department of Justice's manual entry on this family of offences. Particularly relevant is this quote: As part of proving that the defendant acted knowingly or intentionally, the attorney for the government must be prepared to prove that the defendant was aware of the facts that made the defendant’s access unauthorized at the time of the defendant’s conduct. Given your stipulation that the person has unintentionally viewed or downloaded the material without authorization, this would not be a violation of 18 U.S.C. § 1030.
This isn't about bullying at all, this is about Virginia being a "one-party" state. Virginia Law 19.2-62 outlines that: B.2 It shall not be a criminal offense under this chapter for a person to intercept a wire, electronic or oral communication, where such person is a party to the communication or one of the parties to the communication has given prior consent to such interception. However what is not said in the article is that the daughter didn't know that the recording device was in the backpack. This means that the mother did not get consent from either party being recorded (it isn't clear that a minor could give consent anyway), and is therefore in violation of 19.2-62. The (US) law has been quite clear on "two wrongs don't make a right", the mother was not getting satisfaction through other channels, but that does not mean she is right in violating the law in pursuit of justice. This is still very much in the early stages of this particular case, but I'm willing to bet that the mother will see very little if any punishment in this matter. As for why the DA doesn't prosecute the children (or their parents) for the bullying, this really depends on what kind of bullying is subject here. If the children are verbally bullying, this may not be a crime (yes, it is morally wrong, but may not be a crime). It isn't to say though that the children in this case haven't been reprimanded according to State law, at least the subject of the bullying has been moved to a different class as a result. Unless the bullying reaches a physical level, most State laws require the schools to deal with the bullying directly (through moving children to different classes, suspensions, expelling, etc), so the DA doesn't typically get involved until physical injury occurs.
