The move came after the country's Supreme Court nullified the result of the August vote and ordered a re-run within 60 days, saying incumbent President Uhuru Kenyatta's victory by 1.4 million votes was undermined by irregularities.
"Since the Supreme Court delivered judgment. these threats have become more aggressive", Maraga said in a briefing with reporters outside the court, adding that individual judges and their staff have become subject to numerous threats on social media.
Analysts fear that with the bashing received from the judges, the IEBC may have lost the moral credibility to organise a new poll in less than a month.
The presidential results announced by the Independent Electoral and Boundaries Commission (IEBC) met all the required standards, a Supreme Court judge has said.
He said that until that was achieved, he and his colleagues were prepared to pay "the ultimate price" to safeguard the rule of law.
The judgement was given after NASA leader, Raila Odinga filed a petition against Mr. Kenyatta's election, arguing that process through which the transmission of presidential vote results was done did not conform with constitution.
Odinga claimed that the criticism of Maraga - who was part of the panel that nullified the election result - was an attack on his community.
"Our order of scrutiny was a golden opportunity for the IEBC to place before the court evidence to debunk the petitioner's claim", Mwilu read from the court's detailed judgement on Wednesday.
"But what did IEBC do with it?"
The justices went on to enumerate other failings, including the electoral commission's "contemptuous disobedience" of a court order demanding that it grant access to its computer servers so they could be scrutinized.
They said the court should have ordered for a recount of the votes following a petition filed by the Nasa coalition after Uhuru Kenyatta was declared victor of the August 8 election.
In Kenya's electoral system, official tally forms were to be sent from all 291 constituencies and 40,883 polling stations to the national tallying center.
Judges described the obscurity around the forms 34A as a "mysterious puzzle of labyrinthine proportions". And, she says, the judges understand these implications.
Earlier on Wednesday, Deputy Chief Justice Philomena Mwilu said the electoral agency's system was infiltrated and data contaminated.
"Elections are not only about numbers", judge Mwilu said.
The court has set a new election date for October 17.
Doubts are growing over Kenya's ability to hold a rerun of its presidential election in just one month as key players remain unable to agree on how to conduct a credible vote.
The court has earned worldwide praise for its landmark decision to void the results, hailed as the first of its kind in Africa, even as concerns about a political crisis in Kenya grow.
