A parliamentary spokeswoman reported that the lack of emails was not due to the attack directly, but because of precautionary measures as a result.
The damage, if any, has not been assessed yet.
This attack comes at an interesting time in British politics, after a snap general election and of course amid Brexit.
Only a few weeks ago, the global ransom ware attack affected systems across the NHS, the national health care organisation for the UK.
The terror attack at Westminster in May prompted Amber Rudd, Home Secretary, to call for WhatsApp to remove its encryption services to aid counter terrorism.
Hopefully, this digital attack will make MPs, who are arguably uneducated and out of touch with the technology they are making legislation on, recognise the importance of encryption and security when their own systems are threatened.
However, the Conservative government has shown promise in regards to introducing legislation to improve the digital age; the Queen's speech, where the new government sets out it's legislation for its term, included a bill enabling citizens to instruct online services to remove their data and content when they turn 18.
I find the bill good in its intent, but I am skeptical of the government's ability to enforce it, should it become legislation. I feel unilateral agreement with have to be made internationally to truly achieve this.
