Of expressive origin.
The similarity with English hack is most likely nongenetic. The semelfactive ха́квам (hákvam), however, can mean “to hack (a computer programme)” within the right context. That meaning has been borrowed from English.
ха́кам • (hákam) first-singular present indicative, impf (perfective ха́кна)
