I heard that during Christmas a lot of customer data was stolen using malware attack called Ram Scrapers.
What exactly is a Ram Scraper?
How would one infect a machine with it?
What information can you take with a Ram Scraper?
How to detect if you have Ram Scraper installed?
And how to protect yourself against Ram Scrapers?
Sorry if this is a stupid question. But I am very curious about it since it seems to have affected a huge amount of stores.
Thanks to anyone for their help and explanation.
