How Did the Wiseasy Hack Occur?

Wiseasy staff use a cloud-based dashboard for remotely managing fee terminals. This dashboard permits the corporate to carry out a wide range of configuration and administration duties corresponding to managing fee terminal customers, including or eradicating apps, and even locking the terminal.

Hackers had been in a position to acquire entry to the Wiseasy dashboard by infecting worker’s computer systems with malware. This allowed hackers to achieve entry to 2 totally different worker’s dashboards, finally main to an enormous harvesting of fee terminal credentials as soon as they gained entry.

High Classes Realized from the Wiseasy Hack

1 — Transparency is not all the time the very best coverage

Whereas it’s simple to easily dismiss the Wiseasy hack as stemming from an unavoidable malware an infection, the reality is that Wiseasy made a number of errors (in response to the Tech Crunch article) that allowed the hack to succeed.
