What is the Attack?<\/p>\n
An attack campaign led by the 8220 gang has been seen leveraging a 3-year old Oracle WebLogic Server vulnerabilities (CVE-2020-14883 which is commonly chained with CVE-2020-14882) to distribute malware. The attackers are able to download maliciously crafted XML files, allowing remote code execution, and finally deploying stealer and cryptominer malware such as AgentTesla, rhajk, nasqa. The high IPS detection rate suggests that the exploitation is at large.<\/p>\n
