DHS Warns of Increasing Attacks on ERP Systems

Following reports by Digital Shadows and Onapsis, the US Department of Homeland Security has issued a warning to businesses that nation-states and other groups are targeting Enterprise Resource Planning systems.



The US Department of Homeland Security has issued a warning to businesses that their Enterprise Resource Planning (ERP) systems are being increasingly targeted for attack, whether it's espionage, sabotage or financial fraud crimes.

It's also not one group that is behind these increases in ERP attacks. DHS is warning that nation-states, "hacktivist" groups and cybercriminals are all increasingly targeting these enterprise systems.

The DHS warning, which was issued July 25 through the US Computer Emergency Readiness Team (US-CERT), follows two reports by Digital Shadows and Onapsis that outlined these increasing threats to ERP software.

Over the past several years, enterprises large and small have been investing more in ERP, with Oracle and SAP as leading providers of this type of software. Microsoft is also a major player. What makes these systems a tempting target is the amount of data about companies they contain, including information related to supply chains, logistics, lifecycle management, human resources, marketing and, most importantly, financial details, results and billing information.

In addition, more ERP software is cloud-based, meaning data is moving from on-premises data centers to cloud service providers.

The Onapsis report notes:

Despite the relevance of these business-critical platforms to the operation of businesses and modern economies, the information security community has suffered from a lack of information regarding the tactics, techniques and procedures (TTPs) used by threat actors when targeting these systems for cyber espionage, sabotage and financial fraud attacks.

Security research found at least seven different hacktivist groups, including some associated with the Anonymous collective, targeting SAP and Oracle ERP applications. Additionally, several botnets based on the Dridex banking Trojan have been updated between last year and this year to specifically target SAP systems in order to steal credentials and access the internal infrastructure of different companies.

Nation-states and groups associated with specific countries are also increasingly targeting ERP applications in order to steal data or carry out cyber espionage.

Specifically, the researchers note that on the Dark Web and other forums, attackers are increasingly looking for and trading exploits that target SAP's HANA in-line memory database. Overall, the report found about 4,000 patches for security vulnerabilities in SAP's offerings, and more than 5,000 security patches for Oracle.

Different groups have been trying to exploit ERP systems since at least 2012, but the first major breakthrough happened in 2014, when cyber attackers based in China exploited a SAP flaw to steal data from the US Information Service (USIS), which provides background investigations to the federal government, according to the report.

Now, these types of attacks are becoming more routine, with attackers not only stealing data, but also installing software to mine cryptocurrencies, according to the report.

For years, enterprises believed that since these systems were within the network and behind a firewall, the applications were safe. However, increased use of cloud-based software is giving attackers new areas to exploit.

"While some executives still consider 'behind-the-firewall' ERP implementations to be protected, we have observed clear indicators of malicious activity targeting environments without direct internet connectivity," the report concludes. "Further, there is an astonishing number of insecure ERP applications directly accessible online, both on-premise and in public cloud environments, increasing the attack surface and exposure."

Joseph Kucic, the chief security officer at Cavirin, which provides security tools for hybrid cloud environments, notes that many ERP applications started off as only on-premises software. Over time, these applications gained cloud components as vendors grew their offerings through acquisition, and customers changed the way they bought software.

"As cyber hackers are becoming more sophisticated and focusing on higher value targets, these legacy ERP providers mentioned in the report are great targets as they originally started as internal only applications then later on acquired additional bolt-on components," Kucic wrote in an email to Security Now on Wednesday.

"Most ERP application security controls (and both internal and external audits) were focused on configuration controls and did not focus on vulnerabilities given their original internal only usage," Kucic added. "Since these firms are growing by bolt-on acquisition strategic components (example SAP acquisition of Concur) there are extensive publicly exposed elements and those vendors lacked the focus that Cloud Born Application Security and Vulnerability have (i.e. Salesforce, ServiceNow, Workday, etc.) had in place since day one."
