# Investigation of Log4j Vulnerability with Tecan and Hamilton Liquid Handlers

On December 10, 2021, Illumina was made aware of a vulnerability in the Apache Log4j software suite (CVE-2021-44228, CVE-2021-45046, and CVE-2021-44832). This software component is a Java-based logging utility and part of the Apache Logging Services Foundation products.

Following notification of these vulnerabilities, Illumina initiated an investigation to identify potentially affected products and assess any associated risks. The investigation determined that the Tecan/Illumina Automated Pipetting System (IAPS) and Hamilton Liquid Handlers/Illumina Amplification System (IAS) are **not affected** by these vulnerabilities.

Illumina takes data security and privacy concerns seriously and remains committed to evaluating and addressing potential cybersecurity risks. Illumina hopes this information helps alleviate concerns regarding these vulnerabilities.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://knowledge.illumina.com/microarray/tecan-iaps/microarray-tecan-iaps-reference_material-list/000006339.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
