In June, Iran was responsible for a ‘brute force’ cyberattack on Parliament lasting over twelve hours. It was initially thought that Russia was behind the attack, but intelligence officials now conclude Iran was responsible. It was Tehran's first significant cyberattack on the UK. Hackers repeatedly probed ‘weak’ passwords of politicians and aides, forcing parliamentary officials to lock MPs out of their own email accounts as they scrambled to minimise the damage. The network affected is used by every MP, including the Prime Minister and her cabinet ministers. Nine thousand email accounts were affected. The revelations come after Britain, Germany, and France tried to keep the nuclear deal with Iran, agreed in 2015, on track after President Trump’s refusal to back it.  Trump stopped short of ripping up the deal, but said that it would be terminated unless measures were taken to ‘toughen it up’. He believes the international community is being ‘naïve’ in its dealings with the regime.
