DarkVishnya: Attacking from the Inside – Again

Written by: Mike Parkin, Attivo Networks Product Marketing Engineer – Once again, cyberattacks that rely on physical access have made headlines. This time, the culprit is an attack dubbed DarkVishnya that came to light targeting banks in Eastern Europe. This sophisticated attack relies on intruders placing devices on the physical network, ranging from inexpensive laptops or Raspberry Pi type devices, to Bash Bunny style USB devices that can be placed unobtrusively into an office or branch location. By using a built in, or attached, GPRS/3G/LTE wireless module, the attackers can remotely access their malicious kit, in this case, breaking into networks to steal tens of millions of dollars.
