A lot of Taliban funding comes from Pakistan's ISI, as well as individual elements in Arab countries (prominently Saudi Arabia - wealthy ultra religious folks who might even be distant members of the royal family, but not affiliated to government). Apart from that, the Taliban do have the drug trade to keep them afloat. There are a few enough Russians in Afghanistan, but afaik, the Taliban are mostly ambivalent to them now. The Taliban mostly targets 3 types of folks - US and NATO people, Afghan government people, and open allies of the Afghan government (countries like India). Uzbekistan and Iran maintain very tight borders with Afghanistan so that the fighting doesn't spill over. For a very interesting tidbit, even very recently, Taliban was fighting ISIS near Badakhshan and Nuristan.
