Exploits of the Java vulnerabilities have been observed in the wild in exploit kits such as Blackhole, which are key enablers of drive-by-downloads of malware. In addition to applying the content release, it is recommended that customers consider the following controls and safeguards: * Tightly control the movement of .JAR files, especially from the Internet. JAR files are used to deliver the malware from these drive-by-downloads, and policies should ensure that JAR files are only accepted from internal or highly trusted sources, and only allowed to Java-enabled systems that have a need for JAR files. Furthermore consider blocking JAR files in unknown traffic or from high-risk or unknown URL categories. * Disable Java in web-browsers for end-users who don't have a requirement for Java. Users who have a need for Java should consider dedicating a browser for Java-enabled uses, and a non-Java-enabled browser for use on the Internet. *** ** * ** *** ## Related Blogs ### [Secure the Enterprise](https://www.paloaltonetworks.com/blog/category/secure-the-enterprise/?ts=markdown) [#### 8 Tips for Surviving Black Hat and Other Hostile Networks](https://origin-researchcenter.paloaltonetworks.com/blog/2019/08/tips-for-surviving-black-hat/) ### [Announcement](https://www.paloaltonetworks.com/blog/category/announcement/?ts=markdown), [Must-Read Articles](https://www.paloaltonetworks.com/blog/security-operations/category/must-read-articles/?ts=markdown), [Reports](https://www.paloaltonetworks.com/blog/category/reports/?ts=markdown), [Threat Advisories - Advisories](https://www.paloaltonetworks.com/blog/category/threat-advisories-advisories/?ts=markdown), [Unit 42](https://unit42-dev2.paloaltonetworks.com) [#### 2026 Unit 42 Global Incident Response Report --- Attacks Now 4x Faster](https://origin-researchcenter.paloaltonetworks.com/blog/2026/02/unit-42-global-ir-report/) ### [AI and Cybersecurity](https://www.paloaltonetworks.com/blog/security-operations/category/ai-and-cybersecurity/?ts=markdown), [Must-Read Articles](https://www.paloaltonetworks.com/blog/security-operations/category/must-read-articles/?ts=markdown), [News and Events](https://www.paloaltonetworks.com/blog/security-operations/category/news-and-events/?ts=markdown) [#### Cortex XDR is the Only Endpoint Security Market Leader to Achieve 99% in Both Threat Prevention and Response in AVC EPR](https://origin-researchcenter.paloaltonetworks.com/blog/security-operations/cortex-xdr-is-the-only-endpoint-security-market-leader-to-achieve-99-in-both-threat-prevention-and-response-in-avc-epr/) ### [Product Features](https://www.paloaltonetworks.com/blog/sase/category/product-features/?ts=markdown), [Products and Services](https://www.paloaltonetworks.com/blog/category/products-and-services/?ts=markdown) [#### A New Phishing Frontier: From Email to SaaS Collaboration Apps](https://origin-researchcenter.paloaltonetworks.com/blog/sase/a-new-phishing-frontier-from-email-to-saas-collaboration-apps/) ### [Playbook of the Week](https://www.paloaltonetworks.com/blog/security-operations/category/playbook-of-the-week/?ts=markdown) [#### Playbook of the Week: Using YARA to Automate Malware Identification and Classification in XSOAR](https://origin-researchcenter.paloaltonetworks.com/blog/security-operations/playbook-of-the-week-creating-threat-hunting-rules-in-cortex-xsoar/) ### [Next-Generation Firewalls](https://www.paloaltonetworks.com/blog/network-security/category/next-generation-firewalls/?ts=markdown) [#### Always Innovating: User Experience, Threat Coverage and Management](https://origin-researchcenter.paloaltonetworks.com/blog/network-security/always-innovating-july-2023/) ### Subscribe to the Blog!
