Hacking

The vendor, SitusAMC Group Holdings, LP, said in a statement Saturday that someone compromised its systems and took client data including "accounting records and legal agreements." 

Some security experts have warned that Iranian hackers may go after U.S. targets, including financial services companies, in retaliation for the U.S. government's assassination of Iranian military leader Qassem Soleimani.

Equifax, the credit-reporting firm that suffered a massive data breach last year, said it will notify an additional 2.4 million U.S. consumers that they were affected by the hack.
