Targeted Attacks Leveraging Domain Credentials
Date: 29 July 2014
The purpose of this Alert is to bring attention to targeted attacks using compromised domain credentials.
CCIRC has received a report of advanced persistent threat (APT) activity in ongoing targeted attacks using compromised domain credentials.The apparent objective of this activity is the theft of intellectual property, trade secrets, and other sensitive business information. Although this activity appears to be limited at the time of writing, it is important to note that this type of attack is highly adaptable and can be used to target various critical infrastructure industries.
- CCIRC recommends that organizations review Microsoft Security Advisory 2963983 and consider implementing the suggested workarounds to help mitigate the risks.
- Consider installing Microsoft's Experience Mitigation Toolkit 4.1 (EMET). The Enhanced Mitigation Experience Toolkit (EMET) helps mitigate the exploitation of vulnerabilities by adding additional protection layers that make them harder to exploit. NOTE: EMET 3.0 does not mitigate this issue.
- Review CCIRCs Mitigation Guidelines for Advanced Persistent Threats (TR11-002) that helps define APT, describes typical APT attack methodologies and to introduces mitigation and monitoring techniques that may reduce the risk to organizations.
- Implement the first 4 of the Top 35 mitigations, as noted in CCIRC's TR11-002 Mitigation Guidelines for Advanced Persistent Threats.
