Most of the time. If you see it advertised broadly it's usually a scam. You don't need to advertise legitimate work-from-home opportunities.
See, there are billions of people on this earth who would love to make $1,000/month, and they are willing to do a lot more than sit from home. Being able to work from home is attractive to a large portion of the world's population as well. So there's a bit of an imbalance between the supply and demand for this kind of work.
There certainly are legitimate jobs you can do from home (I work from home) but you usually need a skill and you may need to go so far as making the job yourself (i.e. start a business).
So if you have a skill you can offer as a service online you might want to check out sites like elance or search for other freelance marketplaces. You can sign up for jobs writing, researching, etc. There's also Amazon Mechanical Turk (but most of the jobs won't make much money, check it out if you can do transcription or translating), ebay (lots of people make a living from home by reselling things on ebay) and many other legitimate ways to make money online.
But most of the time you see "work from home!" as copy, it's going to be some kind of scam (in a common one you sign up for promotions that they get money for, and they give you a small cut. You sign up for credit cards, etc, and make pennies).
