MOSCOW, August 15 Google has confirmed hacker attacks allegedly from Iran on the headquarters of US President Joe Biden, as well as on the campaign headquarters of ex-President Donald Trump.
«APT42 (the name of the alleged hacking group — ed.), an entity backed by the Iranian government… in May and June, targeted the personal email accounts of about a dozen people associated with President Biden and former President Trump, including current and former U.S. government officials and people associated with the election campaigns,» the report, published on Google's website, says.
The report also said the alleged hacker group «has shown no intent to stop attempting to compromise» accounts and has been using new tactics.
Google warned both headquarters that the company is seeing «increased malicious activity coming from other countries,» stressing the need to take security measures to protect email accounts.
The alleged hackers were reported to have broken into the Gmail account of a «senior political consultant,» although Google did not specify whether the account belonged to Trump supporter and former adviser Roger Stone. 
Earlier, the Washington Post reported, citing sources, that the FBI in June launched an investigation into alleged hacking attempts allegedly from Iran, aimed at advisers to the campaign of US Vice President Kamala Harris, as well as the campaign headquarters of former US President Donald Trump. Three employees of the Biden-Harris campaign received phishing emails that could have given the attacker access to messages. According to the newspaper, the phishing attempt apparently led to the hacking of the correspondence of at least one person formally not associated with either campaign — Trump supporter and former adviser Roger Stone.
American media previously reported that Trump's campaign was subjected to a cyberattack by foreign hackers. It was claimed that the hackers allegedly gained unauthorized access to the campaign's internal correspondence. US law enforcement agencies did not rule out that Iran was behind the cyberattack.
At the same time, speaking at a briefing on Monday, White House spokesperson Karine Jean-Pierre refused to confirm the veracity of the claims about Tehran's involvement in the cyberattack on the Republican politician's headquarters.
