Kaspersky is reporting on a series of bank hacks -- called DarkVishnya -- perpetrated through malicious hardware being surreptitiously installed into the target network:
In 2017-2018, Kaspersky Lab specialists were invited to research a series of cybertheft incidents. Each attack had a common springboard: an unknown device directly connected to the company's local network. In some cases, it was the central office, in others a regional office, sometimes located in another country. At least eight banks in Eastern Europe were the targets of the attacks (collectively nicknamed DarkVishnya), which caused damage estimated in the tens of millions of dollars.
Each attack can be divided into several identical stages. At the first stage, a cybercriminal entered the organization's building under the guise of a courier, job seeker, etc., and connected a device to the local network, for example, in one of the meeting rooms. Where possible, the device was hidden or blended into the surroundings, so as not to arouse suspicion.
The devices used in the DarkVishnya attacks varied in accordance with the cybercriminals' abilities and personal preferences. In the cases we researched, it was one of three tools:netbook or inexpensive laptop Raspberry Pi computer Bash Bunny, a special tool for carrying out USB attacks
Inside the local network, the device appeared as an unknown computer, an external flash drive, or even a keyboard. Combined with the fact that Bash Bunny is comparable in size to a USB flash drive, this seriously complicated the search for the entry point. Remote access to the planted device was via a built-in or USB-connected GPRS/3G/LTE modem.
