Supply chain security guidance

Many modern businesses outsource their data to third party companies which aggregate, store, process, and broker the information, sometimes on behalf of clients in direct competition with one another.

Such sensitive data is not necessarily just about customers, but could also cover business structure, financial health, strategy, and exposure to risk. In the past, firms dealing with high profile mergers and acquisitions have been targeted. In September 2013, a number of networks belonging to large data aggregators were reported as having been compromised.

A small botnet was observed exfiltrating information from the internal systems of numerous data stores, through an encrypted channel, to a botnet controller on the public Internet. The most high profile victim was a data aggregator that licenses information on businesses and corporations for use in credit decisions, business-to-business marketing and supply chain management. While the attackers may have been after consumer and business data, fraud experts suggested that information on consumer and business habits and practices was the most valuable.

The victim was a credit bureau for numerous businesses, providing “knowledge-based authentication” for financial transaction requests. This supply chain compromise enabled attackers to access valuable information stored via a third party and potentially commit large scale fraud.
