1. An apparatus for detecting anomalous automated teller machines (ATMs), comprising:
a memory configured to store a set of baseline signals associated with an ATM, wherein the set of baseline signals comprises electromagnetic signals propagated from internal components of the ATM when the ATM is initiated to operate; and
a processor operably coupled with the memory, and configured to:
obtain a set of test signals that comprises electromagnetic signals propagated from the internal components of the ATM;
extract a set of test features from the set of test signals, wherein the set of test features indicates a test profile of the ATM;
extract a set of baseline features from the set of baseline signals, wherein the set of baseline features comprises expected electromagnetic radiation patterns associated with the internal components of the ATM;
compare each of the set of test features with a counterpart baseline feature from among the set of baseline features;
determine a deviation between the set of test features and the set of baseline features;
determine that the deviation between the set of test features and the set of baseline features is more than a threshold percentage; and
in response to determining that the deviation between the set of test features and the set of baseline features is more than the threshold percentage:
determine that an unverified device is installed at the ATM causing the deviation between the set of test features and the set of baseline features; and
disable data communications between the apparatus and the ATM.
