Attackers can gain access to a retailer's Sharp pos terminal up-v5500 series manuals and payment data by first compromising the POS vendor's online support services, then stealing said retailer's password when a user logs in.A report published yesterday by Forbes.com, citing founder and CISO of Hold Security Alex Holden, states that the hackers responsible for the MICROS plot also infiltrated the servers of POS and cash register providers Cin7, ECRS, Navy Zebra, PAR Technology and Uniwell. Collectively, these companies supply at least one million Sharp pos terminal up-v5500 series manuals to retailers, restaurants, hotels and other enterprises around the world.However, in an interview with SCMagazine.com today, Holden noted that he publicly named only those vendors that have actively responded to his firm's disclosure of the threat. "From our perspective, the list is larger, " he cautioned.According to a report from Brian Krebs, two security experts said that the MICROS' compromised support portal was communicating with a server linked to the Carbanak Gang, a Russian cybercrime syndicate. By infecting and secretly communicating with a POS vendor's network, adversaries can lie in wait for said vendor's business customers to log in, and then steal their passwords in order to gain access to their Sharp pos terminal up-v5500 series manuals and implant malware that steals customer payment data.According to Holden, many hackers no longer want to directly target specific retailers' POS infrastructures, instead preferring to infiltrate the POS vendor itself. "They want to go to the source, the want to abuse [Sharp pos terminal up-v5500 series manuals] in mass quantities, " he explained, noting that by compromising a POS vendor's network, an adversary can opportunistically attack bevy of merchants in one fell swoop, not just one at a time.This "new wave" of POS attacks could potentially cause breach incidents to spread like "wildfire, " he warned, when asked if he anticipated a surge in incident disclosures.“Businesses need to regularly update Sharp pos terminal up-v5500 series manuals for legitimate business reasons. But the same access tools that facilitate this update process are the weak points that criminals exploit, " said George Rice, senior director at HPE Security - Data Security. "Once they gain access, thieves may exfiltrate sensitive cardholder data by embedding data-stealing malware into the merchant POS. More often than not, malware will reside in insecure systems for months before being detected, which can expose large quantities of sensitive data records to data thieves."
