'An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled,' the Apache Foundation said in an advisory. The bug has scored a perfect 10 on 10 in the CVSS rating system, indicative of the severity of the issue. Tracked as CVE-2021-44228 and by the monikers Log4Shell or LogJam, the issue concerns a case of unauthenticated, remote code execution (RCE) on any application that uses the open-source utility and affects versions Log4j 2.0-beta9 up to 2.14.1.

Here's a few short searches that I have not seen appear EXCEPT where exploit attempts are being tried.The Apache Software Foundation has released fixes to contain an actively exploited zero-day vulnerability affecting the widely-used Apache Log4j Java-based logging library that could be weaponized to execute malicious code and allow a complete takeover of vulnerable systems. Since then, there has been further attempts that obfuscate strings. You can see it in the SOC Prime sigma rule: That 45 ip address has been seen in multiple honeypots/logs, it appears it's scanning everything on the internet. Just patch, listen to your corporate IT folks, and keep your eyes and ears open. This doesn't mean you, the home user, needs to panic. You don't have to understand all of it, but it will give you an idea of the scale, especially that Github link in the second post. One thread you might want to read is this. Until that happens, not exposing things to the internet makes it harder for attackers to get to you, and if one somehow does, antivirus will -hopefully- help prevent them from dropping something bad on your computer. Patching things will make sure that, when a vendor does resolve this problem, the fix gets to you. In this specific case keep systems, applications, and devices up-to-date (patch things), don't expose anything at your home directly to the internet, and run updated antivirus. The best advice I think there is for general population is to continue following best practices. Doing vendor contact isn't something I would lose sleep over though. If you know of an important or large scale app, especially one written in java, it wouldn't hurt to look for a vendor response or try to bug them about providing one. setting system properties, web application firewalls, application whitelisting, centralized logging, etc.). This isn't something end users can easily fix, mitigate, or watch for on their own in the same way enterprise IT is (e.g.

This is something I think we'll be finding in dark corners for years to come though. Remember, over 3 billion devices run Java! Most of the focus is on enterprise right now though, so there isn't a good list of the little things. Ubiquiti I know is affected (consumer/prosumer level network equipment), MATLAB reportedly is (desktop engineering software), and ZAP (desktop cybersecurity tool) are three I can think of. There are generic (home) apps/devices that use log4j, anything built in/using Java may use it. This may be an equally good explanation: Ģ) TLDR Don't expose things directly to the internet, keep everything patched, run antivirus. I can control the log input, what system it asks the question to, and the answer. The answers to these questions can be malicious. Someone on twitter asked two questions that I thought might be valuable for this article, paraphrasing: Can someone explain the Log4j vulnerability in non-IT terms, and is there any mitigation my level as average mere mortal?ġ) A log component can ask external systems questions.
