Well this sucks.
While the dust is settling on the British Airways compromise, the Magecart actor behind it has not stopped their work, hitting yet another large merchant: Newegg. The breach of Newegg shows the true extent of Magecart operators’ reach. These attacks are not confined to certain geolocations or specific industries—any organization that processes payments online is a target. The elements of the British Airways attacks were all present in the attack on Newegg: they integrated with the victim’s payment system and blended with the infrastructure, staying there as long as possible.
