A world financial watchdog says the rise in employees working from home has resulted in a sharp increase in cyberattacks.The watchdog is the Switzerland-based Financial Stability Board (FSB). It oversees financial rules for the G20, a group of 20 major world economies.In a new report to G20 finance ministers and central banks, the FSB said that having more employees working from home created new possibilities for internet criminals.The rise in remote workers worldwide happened because of restrictions linked to the COVID-19 pandemic.Many companies are expected to continue permitting some employees to work at home in some form.Most internet systems were not prepared to deal with widespread remote working "and the exploitation of such a situation by cyber threat actors," the FSB said.The report examines some lessons that were learned from the effects of the pandemic on financial businesses.
