Google has issued a warning about a new tactic used by cybercriminals. These groups are targeting employees of major financial and investment firms in the United States.
The hackers are using phone scams to steal sensitive information. They also try to extort money from their victims.
Google's security researchers identified the method as voice phishing, also called vishing. This involves attackers calling people and pretending to be someone they are not.
The goal is to trick employees into revealing confidential data. This data could include account details, personal information, or company secrets.
The attackers then use this stolen information for further criminal activities or to demand payment.
Financial firms are particularly vulnerable due to the sensitive nature of the data they handle.
Google has not named the specific firms targeted but emphasized the widespread threat to the financial sector.
The company advises employees to be cautious of unsolicited calls asking for personal or financial details.
