The Log4J Vulnerability: News And Analysis


The critical vulnerability disclosed Dec. 10 in Java logging package Log4j has sent shockwaves throughout the industry given how frequently that open-source library is used to develop enterprise software. Log4j can be found in software used by everyone from Apache and Apple to Minecraft and Twitter, giving threat actors an enormous attack surface where they can cause widespread global disruption.

Remote code execution exploits like Log4j are innately dangerous since hackers can carry out an attack with a single line of text. That text can trigger an application to begin a process that eventually grants an adversary the opportunity to run any code they would like on the target.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has urged vendors to immediately identify, mitigate, and patch the wide array of products using software from the Log4j library. And the vulnerability is expected to fuel debate in the weeks and months ahead about the risks associated with relying on open-source code libraries like Apache Log4j to build enterprise-scale applications.

Log4j Exploit Is ‘A Fukushima Moment’ For Cybersecurity: Tenable CTO
‘We’re discovering new apps every minute which use Log4j in one way or another. It affects not only the code you build, but also the third-party systems you have in place,’ writes Tenable CTO Renaud Deraison.

Huntress’ John Hammond: Log4j Could Have Been ‘Ransomware Armageddon’
‘It’s very evident that a lot of the technology, a lot of security stacks, a lot of software stacks that managed service providers use are still going to be affected by this. This affects so much, it’s ubiquitous. There’s no mistake, small and mid-market businesses and MSPs are going to see the effects,’ says John Hammond, senior security researcher at Huntress.
