Probably not. I lived in Udon Thani from 2004-2011, though I’ve been a frequent visitor to Thailand since 1978. While living there, I occasionally came across such a story in the Bangkok Post.
If you need to confirm Kasikorn’s reputation, I suggest asking local Thai who are financially self sufficient; korn Jon, or poor folks, would not be targets of inside theft or professional hackers. Though I suppose everyone reads the BP.
People have seen their money disappear from Kasikorn Bank a few times over the years. In nearly every case, the account holders never saw their money again. I remember one case in which a staff member took the money & disappeared; the bank, supported by the police, said they were not to blame.
