“Most, if not almost all, internal applications at Target used Active Directory (AD) credentials and I’m sure the Ariba system was no exception. “I know that the Ariba system has a back end that Target administrators use to maintain the system and provide vendors with login credentials, I would have to speculate that once a vendor logs into the portal they have active access to the server that runs the application,” the source said. The source said Fazio also would have had access to Target’s Property Development Zone portal.Īccording to a former member of Target’s security team who asked not to be identified, when a work order for an external vendor is created, the payment is collected through the Ariba system: Vendors log into Ariba, complete the necessary steps to close out the work order and they are later paid. But how would the attackers have moved from Target’s external billing system into an internal portion of the network occupied by point-of-sale devices? The former Target network expert has a theory: Secondly, the free version is made explicitly for individual users and its license prohibits corporate use.įazio’s statement also clarified that its data connection to Target was exclusively for electronic billing, contract submission and project management. The company did not specify which component(s) of Target’s online operations that Fazio accessed externally, but a former employee at Target said nearly all Target contractors access an external billing system called Ariba, as well as a Target project management and contract submissions portal called Partners Online. However, there are two problems with an organization relying solely on the free version of MBAM for anti-malware protection: Firstly, the free version is an on-demand scanner that does not offer real-time protection against threats (the Pro version of MBAM does include a real-time protection component). To be clear, Malwarebytes Anti-Malware (MBAM) free is quite good at what it’s designed to do – scan for and eliminate threats from host machines. But investigators close to the case took issue with Fazio’s claim that it was in full compliance with industry practices, and offered another explanation of why it took the Fazio so long to detect the email malware infection: The company’s primary method of detecting malicious software on its internal systems was the free version of Malwarebytes Anti-Malware. There is no question that, like Target, Fazio Mechanical was the victim of cybercrime. In a statement (PDF) issued last week, Fazio said it was “the victim of a sophisticated cyber attack operation,” and further that “our IT system and security measures are in full compliance with industry practices.” Through a PR firm, Fazio declined to answer direct questions for this story, and Target has declined to comment, citing an active investigation. Two of those sources said the malware in question was Citadel - a password-stealing bot program that is a derivative of the ZeuS banking trojan - but that information could not be confirmed. Multiple sources close to the investigation now tell this reporter that those credentials were stolen in an email malware attack at Fazio that began at least two months before thieves started stealing card data from thousands of Target cash registers. Last week, KrebsOnSecurity reported that investigators believe the source of the Target intrusion traces back to network credentials that Target had issued to Fazio Mechanical, a heating, air conditioning and refrigeration firm in Sharpsburg, Pa. that exposed credit card and personal data on more than 110 million consumers appears to have begun with a malware-laced email phishing attack sent to employees at an HVAC firm that did business with the nationwide retailer, according to sources close to the investigation.
