There are multiple risks related to SAP CRM systems. Some of them are listed below.
Having access to SAP HR system an attacker can compromise information of the most qualified and competent employees. For example, if a salary of the top executives was revealed, competing HR departments can use this data to to entice those employees by making irresistible job offers.
SAP HR system stores confidential personal information, such as social security numbers. The latter, by the way, can be acquired by means of PA20 transaction. Depending on the country, other personal identifiers and sensitive data could be critical:
As an example, U.S. Department of Energy has been recently hacked, resulting from this was a leakage of personal data of 104,000 employees. As was discovered later, their HR system was directly accessible via the Internet.
An attacker can compromise the data that must be safely stored in accordance with the regulatory requirements (HIPPA, SOX, Safe Harbor etc.). Another scenario is misconfiguring the system so that the data storage would not meet the standards. This way a company would have to pay fines.
Having access to SAP HR system, insiders can change their wages. Since the direct change can be easily detected, the risk lies in changing the number of additional working hours to be processed, which in the end affects the wage. In such a case the fraud is extremely difficult to detect.
Denial of service attack against HR system, for example, if executed on the payday could lead to delays in salary payout, cause a growth of dissatisfaction among employees and in the long run negatively impact their productivity. If this attack is executed with certain frequency, in a difficult economic or geopolitical situation this can even lead to strikes.
