![]() ![]() Unfortunately, it may be some time until full knowledge of how widespread and how impacting this vulnerability will be. These threats are likely going to increase until vendors start to push patches and updates for proprietary products. Installation of Cobalt Strike to enable credential theft and lateral movementĮxfiltration of data from compromised systems Mass CVE-2021-44228 exploitation (pray and spray style) Mass CVE-2021-44228 scanning with various HTTP headers Similarly, both antivirus and endpoint detection and response vendors have observed the following malicious behaviour: This roughly translates to 280k attacks per hour. An example of this string that may be used by researchers and attackers alike is through the Java Naming and Directory Interface:Īccording to the Swiss Government Computer Emergency Response Team, the Log4j attack along which possible mitigation steps at each stage of the exploitation have been detailed in the following diagram.Īs of Decem6:44 EST to 5:46 PM EST, security vendors and researchers have observed an uptick of more than 1.4 million attacks targeting CVE-2021-44228. Various firms have begun tackling and tracking threats taking advantage of the Log4j vulnerability dubbed CVE-2021-44228 and also referred to as “Log4Shell.” This allows an unauthenticated attacker to perform remote code execution when crafting a malicious string through various inputs in the application or affected product. In addition, to know which versions of Log4j make this already difficult task even more difficult. To pinpoint exactly which Java-based services use Log4j is even harder. Whether as an individual or an organization, it is difficult to ascertain exactly which applications, Internet services, products, and/or software depend on Java. What is even more concerning is if you are a software vendor, and your products are using components that utilize Log4j will cause the product to be vulnerable. Since a lot of organizations utilize software from third-party vendors, the list for affected applications is also rapidly growing. ![]() A list has been compiled and verification is currently taking place by the Internet community. The ImpactĪs of the date of publishing, the list of manufacturers and components has been growing. ![]() While many logging frameworks exist in Java, Log4j is by far one of the most popular frameworks used for logging. Since Java has been around for a quarter of a century at this point, this would mean many servers and services on the Internet that utilize Log4j. What is Log4j?Įssentially, Log4j is a Java plugin (called libraries) that is used in many Java-based applications. Soon after the root cause of the vulnerability was determined to be Log4j, news of this zero-day vulnerability was covered virtually on every single security advisory, Twitter, IT firms, and other news outlets. Servers and gaming clients that ran the Java version of Minecraft were at risk of something called “arbitrary remote code execution.” This could be done on inputs that were logged, in the case of Minecraft, an example of an exploitation vector is the in-game chat client. On December 9th, 2021, word of a critical vulnerability first came to light to the Minecraft gaming community.
