In this August 11, 2016, photo, House Minority Leader Nancy Pelosi, D-Calif., speaks at a news conference on Capitol Hill in Washington. The leak was said to have included the private cell phone numbers and email addresses of approximately 200 current and former congressional Democrats.
The posted information appeared to have been gained in the electronic breach of the Democratic Congressional Campaign Committee, the fundraising and campaign arm of Democrats in the House of Representatives.
US House Democratic Leader Nancy Pelosi said on Saturday she has been flooded with "obscene and sick" calls and text messages after a hacker linked to Russian Federation posted personal contact information online for her and hundreds of other Democratic lawmakers and aides.
Just this week, US officials said that the Democratic National Committee hack was broader than previously realized.
Pelosi noted that the hack has been widely reported as part of a Russian cyber attack, although Obama administration officials have not officially attributed it to the Russians. It followed two data breaches involving the Democratic National Committee (DNC) and the DNCC.
Both firms, Fidelis Cybersecurity and ThreatConnect, said the hackers created a fake internet DCCC donation site. "Upon landing, I have received scores of mostly obscene and sick calls, voicemails and text messages", Pelosi told Democrats in a letter.
One major concern are the emails sent to the members or the staff could include website links with malware or phishing attempts to steal identities or financial information.
He advised aides and lawmakers to change their passwords on all accounts and possibly open new email accounts. Should lawmakers or staff receive any threats or observe suspicious activity, they should contact U.S. Capitol Police and local police, he said in the memo.
A phone call was held Saturday evening for members with the House sergeant-at-arms office, and cybersecurity experts who have been investigating the hack.
"This is a sad course of events, not only for us, but more importantly for our country", Pelosi said. Wikileaks leaked multiple emails implicating Debbie Wasserman Schultz in the DNC's efforts to intentionally throw Bernie Sanders aside and promote Hillary Clinton instead.
Rep. Adam Schiff of California, whose cellphone number was revealed in the spreadsheet, said in a statement, "I have every confidence that law enforcement will get to the bottom of this, and identify the responsible parties".
