Following a cyber attack on over 600 Iranian government servers, the parliament's voting system broke down during proceedings on Wednesday, MPs resorting to standing and sitting to signify their agreement or disagreement.

The live broadcast of the parliamentary session was also unavailable on the official website due to the malfunctioning of the voting mechanism following Tuesday's cyber attack claimed by the hacktivist group Uprising till Overthrow, closely linked with the Albania-based opposition Mujahideen-e Khalq (MEK) organization.

It is the latest in a series of high level hacking incidents affecting the government and comes on the eve of the country's upcoming elections, scheduled for March 1st, which have witnessed extensive candidate disqualifications and experts expect turnout to be less than 15 percent, a record low for the regime.

Shahriar Heidari, a member of the National Security Commission of the Parliament, highlighted the vulnerability of the country's cyber security infrastructure, saying, "Given that some government systems have been hacked before, and now the parliament has been hacked, it indicates the weakness of the country's cyber security structure."

Leaked documents from the breach include sensitive materials concerning the Supreme National Security Council's strategies to evade sanctions and internal parliamentary documents, such as the list of MPs' salaries which revealed parliamentarians' salaries range from 1.7 to 2.7 billion rials, equivalent to $3200 to $5000.

Meanwhile, Iranian workers are set to receive a government approved average salary increase of 20 percent starting in March, amid an annual inflation rate of around 50 percent. The new minimum monthly wage has been set at 115 million Iranian rials or about 210 US dollars.
