CISA Releases Industrial Control Systems Advisories

Attacks, Malware

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

Data Breaches, Malware, Social Engineering

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

Attacks, Insights, Malware

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…

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

Data Breaches, Malware, Social Engineering

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

Attacks, Malware

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…

North Korean Threat Actor Using Chrome Extensions to Steal Gmail Data

Attacks, Malware

This threat actor has been seen running similar campaigns in the past, but these recent campaigns drew attention from German government authorities due to targeting “experts on issues relating to the Korean Peninsula.” Government bodies publicly speaking out regarding phishing campaigns is a major step in raising awareness about such attacks, which decreases their effectiveness. This campaign is ongoing, with the malicious domains still appearing to be active. To check for evidence of this attack,…
