ScarCruft’s Evolving Arsenal: Researchers Reveal New Malware Distribution Techniques

Email-based security is one of the most effective methods to help prevent malware infections from occurring in the first place. Utilizing proper email security controls, such as AV scanning and sandboxing for attachments, is highly recommended to help prevent malicious files or URLs from being presented to an end user. In cases where a malicious item may make it through, having strong endpoint security controls, such as an EDR, can help prevent a compromise of…

CISA Releases Industrial Control Systems Advisories

The following ThinServer vulnerabilities are notable: CVE-2023-28756 (CVSS score: 7.5) and CVE-2023-28755 (CVSS score: 9.8), because they could enable an unauthenticated, remote attacker to upload any file to the directory where ThinServer.exe is installed. In addition, a threat actor might use the CVE-2023-28755 vulnerability to replace current executable files with trojanized versions. To reduce security risks, users are urged to update software to the following versions: 11.0.6, 11.1.6, 11.2.7, 12.0.5, 12.1.6, and 13.0.2. Versions 6.x…

Security at the core of Intel’s new vPro platform

Intel has introduced its 13th Generation Core processor line, which the company claims is the first to build threat detection into hardware. In combination with endpoint detection and response (EDR) platforms from Intel partners, the new vPro processors promise a 70% reduction in attack surface compared to four-year-old PCs. Windows 11 systems can also take advantage of vPro’s memory encryption to provide better virtualization-based security. In tests conducted by SE Labs and commissioned by Intel,…

JCDC Cultivates Pre-Ransomware Notification Capability

In today’s blog post, Associate Director of the Joint Cyber Defense Collaborative (JCDC) Clayton Romans highlighted recent successes of pre-ransomware notification and its impact in reducing harm from ransomware intrusions. With pre-ransomware notifications, organizations can receive early warning and potentially evict threat actors before they can encrypt and hold critical data and systems for ransom. Using this proactive cyber defense capability, CISA has notified more than 60 entities of early-stage ransomware intrusions since January 2023, including…

New vulnerabilities found in industrial control systems of major vendors

The US Cybersecurity and Infrastructure Security Agency (CISA) has issued advisories on 49 vulnerabilities in eight industrial control systems (ICS) this week, which are used across multiple critical infrastructure sectors. The vulnerabilities identified by CISA were tracked in products from ICS providers including Siemens, Hitachi, Rockwell, Delta Electronics, VISAM, and Keysight. Many of the vulnerabilities in CISA’s advisory are remotely exploitable, involve low attack complexity, and allow attackers to take control of affected systems, manipulate…

55 zero-day flaws exploited last year show the importance of security risk management

Deploying security patches as quickly as possible remains one of the best ways to prevent most security breaches, as attackers usually rely on exploits for publicly known vulnerabilities that have a patch available — the so-called n-day exploits. But mitigating the risk from vulnerabilities unknown to the affected software developers and don’t have a patch available — the zero-day flaws — requires a careful analysis of the types of actors exploiting them, the geography and…

Proof of Concept Exploits Released for Netgear Orbi Router Vulnerabilities

While exploitation was not seen prior to disclosure, it is likely that these vulnerabilities will start to be exploited by attackers who modify the Proof-of-Concept exploit for their own use. This article demonstrates the need to stay up to date on patching, as the patch was released nearly 3 months before these exploits were made public. Additionally, these vulnerabilities demonstrate the need for a defense-in-depth strategy, as many of these cannot be exploited without requiring…
