### Trend Micro Apex One Error Prevents Executable Files from Starting
A faulty Apex One update from Trend Micro largely cripples affected endpoints. The manufacturer is working on a solution.
---
**Issue Overview:**
Trend Micro is currently investigating issues with its security software, Apex One. After recent updates, executable files no longer start on affected computers. The manufacturer has already stopped distributing the faulty update.
This incident recalls the CrowdStrike disaster from last year. According to the Trend Micro services status page, after an update, the Apex One agent generates an error message containing the phrase "Bad Image", which causes no executable files to start on the affected machines. Trend Micro has also published a support document discussing the specific error message.
---
### Initial Countermeasures
The displayed error message reads:
```
regsvr32.exe - Bad Image
C:\WINDOWS\System32\tmmh_20019_AddOn_8.55.0.1399\TmUmEvt.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.
Error status 0xc000012f.
```
**Advice for affected users:**
Replace the file TmUmEvt.dll with its previous version to restore full system functionality.
---
### Official Statement and Ongoing Investigation
Trend Micro told heise online:
*"This is indeed a faulty update."*
Since the company distributes updates in phases,
*"we were able to stop the faulty update and prevent further customers' machines from being affected."*
The investigation into how many customers are affected and to what extent is still ongoing.

### Recent Related Issues
Most recently, Trend Micro dealt with security issues in Apex One in mid-August. An update to close a security vulnerability—already exploited on the internet—in the on-premises version of the Apex One Management Console had side effects that caused the "Remote Install Agent" feature to stop working. Two weeks later, the company released an update that restored this function.

| ### Threat Assessment: Trend Micro Apex One Faulty Update Incident
#### Overview
The article describes a critical issue caused by a faulty update to Trend Micro’s Apex One security software, which prevents executable files from starting on affected endpoints. This malfunction essentially cripples the affected systems, causing operational disruption. Trend Micro has halted distribution of the problematic update and is working on a resolution.
---
### Technical Details and Impact
- Faulty Update Behavior:
After the update, the Apex One agent generates an error message related to a corrupted or incompatible DLL file TmUmEvt.dll). The error message "Bad Image" and error status 0xc000012f indicate that the DLL is either corrupted or not compatible with the Windows environment.
- System Impact:
The failure prevents any executable files from running, effectively locking down the affected endpoints. This is a severe disruption, as it halts all software execution, not just Apex One-related processes.
- Scope and Scale:
The update was distributed in phases, and Trend Micro stopped the rollout upon detecting the issue. The exact number of affected customers is still under investigation, but the phased rollout likely limited the overall impact.
- Previous Related Issues:
The article references a prior incident in August where an Apex One update caused the "Remote Install Agent" feature to stop working. This indicates a pattern of problematic updates affecting Apex One functionality.
---
### Threat Vectors and Risks
- Operational Disruption:
The immediate threat is operational. Organizations relying on Apex One endpoints face potential downtime or reduced productivity as systems become unusable.
- Security Exposure:
With endpoints effectively disabled or in a degraded state, organizations may be vulnerable to security threats. The inability to run executables could prevent security tools from functioning properly, potentially allowing malware or attackers to exploit unprotected systems.
- Incident Response Challenges:
The issue complicates incident response and remediation efforts. Security teams may find it difficult to deploy fixes or run diagnostic tools if executables are blocked.
- Reputational Damage to Trend Micro:
Recurring update issues may erode customer trust in Trend Micro’s reliability and quality assurance processes.
---
### Mitigation and Recommendations
- Immediate Actions for Affected Users:
- Replace the faulty TmUmEvt.dll with the previous version to restore system functionality.
- Roll back to a known good update or restore systems from backups if necessary.
- Monitor Trend |

Provide Additional Insights | Certainly! Here are some additional insights regarding the Trend Micro Apex One issue described in the article:
1. Nature of the Problem:
The problem stems from a faulty update to Trend Micro’s Apex One endpoint security software. The update causes a critical DLL file TmUmEvt.dll) to become corrupt or incompatible, resulting in the “Bad Image” error. This error prevents executable files from starting on affected machines, effectively crippling endpoint functionality.
2. Impact on Users:
Since executable files cannot start, users may experience a complete halt in running applications, severely impacting productivity and potentially leaving systems vulnerable if security software is non-functional.
3. Technical Details:
- The error message regsvr32.exe Bad Image indicates that the DLL is either corrupted or not compatible with the Windows environment.
- The specific error code 0xc000012f corresponds to a “Bad Image Format” error, often linked to corrupted or mismatched DLLs or executables.
- The DLL in question is part of the Apex One agent, which is critical for the endpoint security functionality.
4. Immediate Mitigation:
Trend Micro advises replacing the faulty DLL with a previous, known-good version. This rollback can restore system functionality until a proper fix or updated patch is released.
5. Trend Micro's Response:
- The company halted the phased rollout of the faulty update to prevent further damage.
- They are actively investigating the scope and impact of the issue.
- This proactive containment mirrors best practices for managing faulty updates in security software.
