“Even nuclear nonproliferation can no longer be taken for granted,” he said. “This caldron of tensions is leading more and more countries to take unpredicted decisions with unpredictable consequences and a profound risk of miscalculation.”
He said he was urging world leaders to stop the escalation.
Hackers target a U.S. government website, vowing revenge for Suleimani’s death.
A United States government website was hacked over the weekend to display messages vowing revenge for General Suleimani’s death and a doctored photograph of Mr. Trump being punched in the jaw.
It was not immediately clear if the attack on the website of the Federal Depository Library Program had come from Iran. But the intrusion was consistent with the work of low-level Iranian hackers who could be acting independently, experts said.
A security analysis by United States officials found that “none of the site’s data was compromised.”
James A. Lewis, a former government official and cybersecurity expert at the Center for Strategic and International Studies in Washington, said hackers probably targeted the first agency they could find “that had weak security.”
He said the hack was probably not conducted by Iran’s more sophisticated team but instead recalled a “low-budget hack of the sort Iran’s ‘patriot hackers’ are known for, including the cheesy imagery.”
Bigger agencies have better defenses and are likely to be safe, Mr. Lewis said.
