A landmark diplomatic agreement, which limits Iran's nuclear programme, could indirectly advance the country's cyber-warfare efforts.

On Tuesday, The Hill reported that the nuclear pact between the US, Iran and other nations left some lawmakers concerned as to how increased revenue in the country, freed up through sanctions relief, might impact cyber-relations.

US Senate Intelligence Committee chairman Richard Burr, R-N.C., for instance, told reporters that “potentially lifting the sanctions fuels [Iran's] support of terrorism, whether that's cyber, [or] whether it's conventional weapons purchases.”

Last year, FireEye noted that Iran-based hacker groups were becoming increasingly sophisticated and could evolve into a hacking superpower.

Furthermore, The Hill reported that in the US, “Cyber-experts have been sparring for months over what effects a successful nuclear pact might have on Iran's rapidly accelerating cyber-programme…Many believe the successful deal gives Iranian cyber-warriors incentive to spare the US from their wrath.”
