What is the ruling of Islamic law, its limits, and the method of dealing with and exchanging information and expertise with Israeli researchers in a foreign company?

The Messenger of Allah (peace be upon him) and his Companions dealt with the Jews through buying, selling, and hiring, even though they consumed usury and illicit gain. The important thing is to avoid prohibited acts in dealings. It is obligatory to boycott them if there is a legitimate benefit in doing so, or if they are warring against Muslims and dealing with them would increase their strength against the Muslims.
