NSA Releases Updated Guidance on Side-Channel Vulnerabilities

The National Security Agency (NSA) has released a Cybersecurity Advisory providing updated guidance for addressing side-channel vulnerabilities that affect Intel, AMD, ARM, and IBM processors. Side-channel vulnerabilities exploit weaknesses in speculative execution to leak information, potentially allowing for account permission protocols, virtualization boundaries, and protected memory regions to be bypassed. Spectre and Meltdown, which were disclosed in January 2018, are an example of this kind of vulnerability.

Schneider Electric EVLink Parking (ICSA-19-031-01)

The NCCIC has published an advisory on use of hard-coded credentials, code injection, sql injection vulnerabilities in Schneider Electric EVLink Parking. Versions 3.2.0-12_v1 and prior are affected. Successful exploitation of these vulnerabilities could allow an attacker to stop the device and prevent charging, execute arbitrary commands, and access the web interface with full privileges. Schneider Electric recommends users setup a firewall to restrict remote access to the charging stations by unauthorized users.

"Operation Manic Menagerie" Uncovers "Extensive Compromise" of Australian Web Hosting Providers

The Australian Cyber Security Centre (ACSC) has just released a report of its technical findings and mitigation advice related to the extensive compromise of at least eight Australian web hosting providers, which it discovered through “Operation Manic Menagerie.” The compromises of these providers may have facilitated compromises of their customers’ websites. The goal of this campaign was financial gain: websites running on compromised servers were modified to insert advertising and to support search engine optimization for other websites.

New Free Self-Assessment for CIS Controls

The Center for Internet Security (CIS), which operates the Multi-State Information Sharing and Analysis Center (MS-ISAC), has launched a free assessment tool to enable security practitioners to track and prioritize their implementation of the CIS Controls. Results from the CIS Controls Self-Assessment Tool (CIS CSAT) can be exported per department or organizational unit, or enterprises can take a more holistic view of the entire organization’s security. With cross-mappings to additional security frameworks, users can also track alignment between other best practices and the CIS Controls.
