1. A system, comprising:
a processor configured to:
receive an indication that an existing natural language processing model, trained to classify textual content, should be retrained;
generate a set comprising a plurality of training samples, wherein the set includes at least one synthetic training sample constructed using one or more linguistic hints, comprising at least one keyword of phrase, about a particular novel attack for which malicious textual communications associated with the novel attack, when processed by the existing natural language processing model, are erroneously classified as benign textual communications;
retrain the existing natural language processing model at least in part by using the set of generated training samples; and
use the retrained model to determine a likelihood that a received communication transmitted by a sender to a recipient poses a risk; and

a memory coupled to the processor and configured to provide the processor with instructions.
