The Log4j JNDI attack and how to prevent it

The disclosure of the critical Log4Shell (CVE-2021-44228) vulnerability and the release of first one and than additional PoC exploits has been an unwelcome surprise for the entire information security community, but most of all those who are tasked with keeping enterprise systems and network secure. The timing of it all could be worse – it could have happened on Christmas Eve, for example – but the news hitting on a Thursday evening/Friday in the run-up … More


Log4Shell update: Attack surface, attacks in the wild, mitigation and remediation

Several days have passed since the dramatic reveal of CVE-2021-44228 (aka Log4Shell), an easily exploitable (without authentication) RCE flaw in Apache Log4j, a popular open-source Java-based logging utility that’s seemingly used by most enterprise applications out there. The existence of the vulnerability and the public release of PoCs exploiting it have made this weekend a nightmare for those that are tasked with mitigating its fallout and keeping company systems and networks secure. Log4Shell update: What … More


Hacker-powered pentests gaining momentum

Critical RCE 0day in Apache Log4j library exploited in the wild (CVE-2021-44228)

A critical zero-day vulnerability in Apache Log4j (CVE-2021-44228), a widely used Java logging library, is being leveraged by attackers in the wild – for now, fortunately, primarily to deliver coin miners. Reported to the Apache Software Foundation by Chen Zhaojun of Alibaba Cloud Security Team, the bug has now apparently been fixed in Log4j v2.15.0, just as a PoC has popped up on GitHub and there are reports that attackers are already attempting to compromise … More


Vulnerabilities in Eltima SDK affect popular cloud desktop and USB sharing services

SentinelOne researchers have unearthed a number of privilege escalation vulnerabilities in Eltima SDK, a library used by many cloud desktop and USB sharing services like Amazon Workspaces, NoMachine and Accops to allow users to connect and share local devices over network. “These vulnerabilities allow attackers to escalate privileges enabling them to disable security products, overwrite system components, corrupt the operating system, or perform malicious operations unimpeded,” the researchers shared. The vulnerabilities affect both the cloud … More


Microsoft vulnerabilities have grave implications for organizations of all sizes

Microsoft software products are a connective tissue of many organizations, from online documents (creating, sharing, storing), to email and calendaring, to the operating systems that enable business operations on the front and back ends, both in the cloud and on premises. Over 1 million companies worldwide and over 731,000 companies in the U.S. use Office 365, and though Microsoft offers no hard stats, some sources suggest there are over 90,000 Microsoft partners facilitating services and … More


December 2021 Patch Tuesday forecast: How do you stack up?

I can’t believe that the end of 2021 is already in sight, and looking backwards, I have to say we’ve had our share of interesting events. If I had to characterize it from a security perspective, I’d say this is the year of supply chain attacks. Prior to January, most of us had rarely heard that term, but then Solarwinds, Kaseya, and others were in the news and we heard it throughout the year. Striking … More

Skybox Security’s network modeling mitigates critical infrastructure security risks

Skybox Security announced new vulnerability management capabilities for operational technology (OT) environments. Available now, the new Skybox Security Posture Management Platform capabilities eliminate cyber exposure across the entire enterprise environment, including IT, hybrid, multi-cloud, and now OT assets. “There is no single solution that will stop cyberattacks, and OT environments are particularly vulnerable. IT/OT convergence demands flexible and vendor-agnostic attack surface modeling to reduce critical cybersecurity risks,” said Haggai Polak, chief product officer, Skybox Security. … More

Extracting value from the interconnected network of risk management

From the CISO to the SOC operator, defenders struggle to maintain complete situational awareness. Holistic approaches to risk management require the implementation of a manageable number of policies and procedures but are tied to an often unmanageable and misunderstood ecosystem of tooling and controls. These inefficiencies are laid bare in frequent public breach reports and are the result of a threat landscape that is increasing in volume, complexity, and novelty. We fail to leverage the … More
