Recently, there has been have several successful skimming attacks in the United States, in other US cities and in Canada. A new type of Ultra-Thin Deep Insert Skimmer that can successfully operate inside Motorised Tamper Resistant Card Readers is being used for this attack.
This new skimmer may significantly increase the number of card jams, but it should be noted that some cards can be successfully skimmed before the occurrence of a jam.
Deep Insert Skimmers cannot be detected or prevented by fascia skimming prevention solutions such as NCR Skimming Protection Solution (SPS) or third-party equivalents.
The most common indicators of deep inserts are card jams and read failures.
Since skimming attacks work in tandem with a hidden PIN capture Camera, Banks should consider the presence of any small holes in vicinity of the Pin pad as being suspicious.
Countermeasures for Ultra-Thin Deep Insert Skimmers are in development by NCR. A mechanical inhibitor is scheduled for release by March 2022, and an internal skimmer detection upgrade is scheduled for the end of Q2.
Card issuers should increase the security checks on any magnetic stripe transaction authorisation that originates from a chip card in an ATM.
Any chip-enabled card which is not processed as an EMV transaction is a possible skimmed card.
