Mississippi officials are unable to establish who is responsible for the hack on electoral websites.
Mississippi Secretary of State Michael Watson (R) said on Wednesday that his agency is unable to determine the perpetrators of a cyberattack that affected state election websites on Tuesday because additional proof is required to pin it down to a specific organization.
Watson stated that the hack rendered the sites "periodically unavailable," but that the "election system was not affected."
According to reports, a Russian hacker outfit claimed credit for the attack. The gang, according to USA TODAY, stated in a Telegram message that it targeted Mississippi's state election websites to "attack the portion that is directly relevant to the elections."
The hackers reportedly stated that they will "strike American Democrats as a present to the Republicans for the elections," with the Democratic National Committee as their first target, according to USA TODAY.
According to a senior official at the Cybersecurity and Infrastructure Security Agency (CISA), the agency is "definitely aware of the [Russian] assertions... However, this is insufficient for the federal government to offer attribution."
Another state hit by a cyberattack on Election Day was Illinois. The state's Champaign County Clerk's Office said on Facebook that it was experiencing network and computer server troubles, which it thinks were caused by hackers.
During a background call with reporters on Tuesday, CISA stated that it was aware of a "handful" of distributed denial of service assaults that temporarily disrupted a number of state election websites, but declined to say how many were affected.
According to a CISA official, not every hack on state election websites on Tuesday was successful, and those that were impacted were promptly restored.
The agency also stated that it has seen no indication that the assaults were "part of a wider coordinated operation."
