Log4j is a critical vulnerability detected in the most used logging tool an open-source logging library by Java application Log4j which used by almost all the computing device. This is not just specific to cloud computing environments, but rather everywhere there is a device with internet access.
When vulnerabilities are found and exploited, with increases risk of cyber attackers could break into your systems, can steal passwords and logins, extract data and important information, financial loss and infect networks with malicious software. But the good thing is that there are patches available but with this come a news that will make you worried is that it will take time to update the Log4j package all over the places where it is exists. What’s worse is an overwhelming majority of legacy software and devices are likely to never receive an update.
Challenges faces by Most of the Organization due to the Log4j Vulnerability
- Identifying what services use the Log4j component
- Pin down which of these services your organization uses
- Check out if these services are vulnerable or not
Detection for Log4j Vulnerability in your Organization
- Check your systems for the use of Log4j and the current version (which is Log4j 2.17.0) used
- Check the list of all vulnerable software
- Contact your software vendors on immediate basis, if using any third-party software
- Set up of Web Application Firewall rules
- Check for all the scanning activity
- Check for any exploitation detected.
The Log4j issue has the potential to cause severe impact to many organisations. As cyber security experts attempt to detect which software and organisations are vulnerable, attackers start to exploit the vulnerability. Initial reports indicate this is likely to include remote control malware and ransomware. However the situation is fluid and changing regularly.
As of December 16th, the majority of attacks are automated and exploratory, with initial reports of more targeted exploitation. Should ransomware be delivered by exploiting this issue, vulnerable computers may be ransomed? If organisations do not have robust internal network cyber resilience, this could spread through the organisation and cause a variety of business impacts including:
- business operations disruption
- the need to disclose where personal data was affected
- costs associated with incident response and recovery
- reputational damage
The range of possible organisational impacts ranges from minimal, to a crippling attack and possible information theft, as well as loss of service. Managing this risk requires strong leadership, with senior managers working in concert with technical teams to initially understand their organisation’s exposure, and then to take appropriate actions. These will be specific to your organisation, so working with and supporting local subject matter experts is essential.
For the Organizations that use Log4j 2 in their own applications and infrastructure should update it on the priority basis. The same will be applied to third-party applications. The version 2.17.0 release fully secures the logging library against the Log4Shell vulnerability.
Since Log4Shell affects numerous systems and attainable to exploit, organizations should act smartly & quickly to secure their systems. To swiftly affected systems, organizations need efficient solutions that can immediately identify vulnerability present in the systems and assist you to prioritize the most critical systems to update first, especially on code running in production.
