" Nintendo Switch owners are being encouraged to lock down their accounts after a wave of fraudulent attacks.
The hacks involve a user logging into a person’s Nintendo account - and often using a linked PayPal account to make expensive purchases.
Several reports say the attacks have intensified in recent weeks, with staff at popular technology and gaming sites among those affected.
Nintendo recommends using two-factor authentication to protect accounts.
The attacks have been going on for months, but appear to have increased in the past few weeks.
One staff member at gaming site Eurogamer had their account accessed, the website reported, as did another at Ars Technica.
Administrators of the Nintendo forum on Reddit also said there had been a “notable” number of reports in the past few days."
