Spreediscount.com is advertising website, that is used by malefactors to display pop-ups and create redirects in Safari or Chrome browsers on MacOS or iOS. Usually, pop-up from Spreediscount.com imitates Amazon storefront page, with messages like: “You’ve won a free Iphone X!“, “You are lucky today“. This scam page offers $1000 Gift Card, iPhone X or Samsung S9 for completing simple survey. Of course, in the end all that user gets is malicious download. Those ads can be result of Mac/iPhone/iPad infection, or they can appear on some infected websites you visit.
