New ModPipe Point of Sale (POS) Malware Targeting Restaurants, Hotels

  • Cybersecurity researchers these days disclosed a new form of modular backdoor that targets issue-of-sale (POS) restaurant management software package from Oracle in an try to pilfer delicate payment information and facts saved in the equipment.

    The backdoor — dubbed “ModPipe” — impacts Oracle MICROS Cafe Organization Series (RES) 3700 POS programs, widely applied application suite dining places, and hospitality establishments to competently handle POS, stock, and labor administration, deployed in restaurant and hospitality sectors largely in the US.

    “What can make the backdoor unique are its downloadable modules and their capabilities, as it contains a customized algorithm created to get RES 3700 POS databases passwords by decrypting them from Windows registry values,” ESET researchers explained in an investigation.

    “Exfiltrated credentials permit ModPipe’s operators access to database contents, like several definitions and configuration, standing tables and information about POS transactions.”

    It really is truly worth noting that details these as credit rating card numbers and expiration dates are secured powering encryption obstacles in RES 3700, thus restricting the sum of beneficial details practical for more misuse, whilst the scientists posit that the actor guiding the assaults could be in possession of a 2nd downloadable module to decrypt the contents of the database.

    The ModPipe infrastructure consists of an initial dropper which is made use of to put in a persistent loader, which then unpacks and hundreds the next-phase payload — the main malware module which is used to set up communications with other “downloadable” modules and the command-and-handle (C2) server via a standalone networking module.

    Main amongst the downloadable modules include “GetMicInfo,” a element that can intercept and decrypt databases passwords utilizing a special algorithm, which ESET scientists theorize could have been executed both by reverse-engineering the cryptographic libraries or by making use of the encryption implementation details obtained in the aftermath of a data breach at Oracle’s MICROS POS division in 2016.

    A second module called “ModScan 2.20” is devoted to accumulating extra data about the put in POS procedure (e.g., edition, database server knowledge), whilst another module by the title of “Proclist” gathers aspects about presently working processes.

    “ModPipe’s architecture, modules and their abilities also show that its writers have intensive information of the focused RES 3700 POS software package,” the scientists stated. “The proficiency of the operators could stem from many situations, together with stealing and reverse engineering the proprietary application product, misusing its leaked parts or acquiring code from an underground market place.”

    Enterprises in the hospitality sector that are utilizing the RES 3700 POS are suggested to update to the newest edition of the program as well as use products that operate up-to-date variations of the fundamental working method.
