Machine learning: good for security or a new threat?

Machine learning is no novelty anymore. On the contrary: every self-respecting startup feels compelled to apply machine learning in its offerings. The hunt for scarce developers has been superseded by a scramble for machine learning experts. Fortunately, many machine learning tasks are similar enough that it is possible to save time and money by using pre-trained models. Open-source models are also available free of charge. But does this all really work as well as it seems?

Low-level Hacking NCR ATM



Many of the systems that power the modern world are supposed to be beyond the reach of mere mortals. Developers naively assume that these systems will never give up their secrets to attackers and eagle-eyed researchers.

There is no such thing as a hack-proof system, merely one that has not been sufficiently tested.
