The evolution of Log4j security vulnerability is molding itself into one of the most severe security flaws, impacting most of the applications by highlighting their unpatched systems that cybercriminals can exploit.
Log4J vulnerability has long-lasting implications on the enterprise’s IT infrastructure. Since the cybersecurity industry veterans identified a significant flaw in the code of the software library called Log4j, they are exploring opportunities to have minimum impact on the business network.
Cybersecurity industry leaders are recommending organizations design a resilient plan to protect their business from threats imposed by Log4j vulnerabilities. Here are a few ways hackers can exploit the Log4j threats.
Cybercriminals are using Log4j threats as vectors
Log4j open-source software library is integrated into many applications and web services globally to log their activity. Malicious actors are exploring the opportunities to bank on the vulnerabilities to infiltrate businesses IT infrastructure and steal confidential data or deploy malicious payloads.
Hackers are leveraging this vulnerability to steal information, access or block control of the compromised systems, and deploy malicious content to other users interacting with the targeted server. Identification of Log4j vulnerabilities enables malicious actors with a massive database of vulnerable systems. Once the cybercriminals spot the vulnerable servers to exploit, they might deploy query services or trigger the log message such as 404 not found or others as vectors to infiltrate the system.
Log4j vulnerabilities might interpret a carefully crafted query message as a common and execute it. Malicious actors might use this approach to access the target servers remotely and compromise other servers to execute a full-blown cyber-attack.

Tips to minimize Log4j vulnerability threat
Real-time detection and better visibility
CISOs should consider designing and implementing better threat detection and visibility protocols across all instances. It is a perfect way to execute a fast and effective security audit to analyze the potential attack patterns. Moreover, implementing an automatic deep audit analysis will assist in identifying compromised devices and the threats imposed by them to mitigate the risk in real-time. Enterprises need to adopt a transparent software supply chain process to gain better visibility. CISOs should consider integrating vulnerability management platforms in their security infrastructure to investigate all externally compromised systems, as Log4j software might leave traces on back-end servers.
Identification and prioritization
Dynamic web application scanning help to reduce the financial costs and opportunities of potential security by spotting vulnerabilities quickly. CISOs should consider developing a detailed and deep infrastructural scanning protocol to identify issues in real-time accurately. Advanced cloud workload protection platforms are capable of segmenting vulnerabilities based on their priority by analyzing potential exploits. Enterprises need to determine variable factors based on the application to evaluate risk breaches and attack stimulation executed on the systems. It is one of the efficient ways to arrange vulnerabilities in order of their urgency and their influence on the daily operations of various variable factors.
Remediate known and potential vulnerable assets in the IT infrastructure
CISOs should consider known and potentially vulnerable devices as compromised systems and immediately isolate them until they are mitigated and verified. Enterprises can decide on the isolation approach based on the severity of the vulnerability and criticality of the asset. Physical isolation of the asset, blocking at the network layer, integrating firewall, and restricting asset communications are a few ways to isolate compromised devices. Additionally, Patching Log4j and other vulnerabilities to the latest version will help to remediate the threat in real-time.
Leveraging automation to enable constant scanning management
CISOs should consider integrating robust security automation tools that continuously monitor the complete IT infrastructure to spot suspicious activity in the network and notify the SecOps teams about potential vulnerabilities. Implementing proactive security protocols will help to scan the entire deployed applications offering an end-to-end software supply chain visibility and delivering probing questions to the entire business network to scan devices. Developing security hygiene and infrastructure with stringent data protection encryption protocols and comprehensive data recovery and identification approaches will help to minimize the impact of Log4j vulnerabilities.
