The digital transf.rm.tion process of.power system. towards sm.rt grids is resulting in im.roved reliability, ef.iciency and situational awareness at the expense of.increased cybersecurity vulnerabilities. Given the availability of.large volum.s of.sm.rt grid data, m.chine learning-based m.thods are considered an ef.ective way to im.rove cybersecurity posture. Despite the unquestionable m.rits of.m.chine learning approaches f.r cybersecurity enhancem.nt, they represent a com.onent of.the cyberattack surf.ce that is vulnerable, in particular, to adversarial attacks. In this paper, we exam.ne the robustness of.autoencoder-based cyberattack detection system. in sm.rt grids to adversarial attacks. A novel iterative-based m.thod is f.rst proposed to craf. adversarial attack sam.les. Then, it is dem.nstrated that an attacker with white-box access to the autoencoder-based cyberattack detection system. can successf.lly craf. evasive sam.les using the proposed m.thod. The results indicate that naive initial adversarial seeds cannot be em.loyed to craf. successf.l adversarial attacks shedding insight on the com.lexity of.designing adversarial attacks against autoencoder-based cyberattack detection system. in sm.rt grids.
