There is a growing trend amongst cybercriminals for attacking the point of sale (POS) systems in retail stores. These attacks allow hackers to extract payment card information which can then be sold on the black market for a considerable profit. After a breech, POS systems can be offline for anything up to 48 hours while the attack is investigated. This can cause serious financial implications for retailers, with some generating up to $100, 000 a day via POS systems. This white paper looks at how enSilo’s Virtual Patching against Advanced Targeted Attacks can allow POS systems to be kept online, even if they have already been compromised.
