How Big Data Help to identify AVTECH Security Flaws

Our ProActive System monitor hundreds of different brand/models of CCTV Equipment daily to monitor their operating status.

During the past 2 weeks, we are gradually alerted to multiple remote viewing failure on multiple CCTV system under our ProActive Monitoring system.

These failure happens with different customers on different ISP.

ProActive System is able to analyse the failure captured and it isolate the failure to a single brand, AVTECH.

The AVTECH systems detected as having issues are multiple systems installed over the course of last 6 years, different model, different firmware with different installation date. Systems are installed on multiple different sites with different network setup, internet router, ISP.

With these information captured, our engineers are able to determine the issues down to security flaws present in the AVTECH Firmware are being exploited. Checks with TrendMicro isolate the issues caused to the malware ELF_IMEIJ, which are specifically targeting AVTECH surveillance equipment.

As such, we are able to send out an high priority email alerts to all customers on mailing list advising them on steps to take to prevent their system from being infected, guides to removal of the infected firmware and also how to prevent further attacks. Alternatively are also presented to customers whose equipment which the manufacture no longer release firmware patches for.

During the initial internal testing of our proprietary ProActive Monitoring Data Analytic system in 2015, it had already identify the weakness of AVTECH and see the potential attacked that could happens. With that knowledge we had ceased to use AVTECH equipment in our installation project since 2015 and had by 2016 migrate all our maintenance and subscription customers to using other brands. This prove to be a decision well made with the aid of our ProActive Monitoring system when malware ELF_IMEIJ infected thousands of AVTECH equipment and prevented our customers who kept their system updated from having their AVTECH CCTV system turn into botnets.

We’ll soon be adding in Analytic Features to enable you to monitor your customers flow through your stores using your existing equipment for free !

More Information

Updates 20 March 2017

A new malware that targets Linux-based Internet of Things (IoT) devices has been detected by Search-Lab, a Security research and development firm. This Linux ARM malware called as ELF_IMEIJ.A exploits a vulnerability in devices from AVTech, a surveillance technology company.

As an AVTech user, you can do the following to protect your device,

  • Change the default admin password (All our Devices are installed with the default password changed)
  • Never expose the web interface of any Avtech device to the internet (Disable Remote Viewing through Internet)

Vulnerabilities on AVTECH CCTV equipment had been found.

Symantec had also issued an update on Norton Security Suites to block certain functionality of the DVR from computers trying to access the system. If you face issues logging to your AVTECH system from the internet, that could also be a possible reason.

LAKSON had stop using AVTECH Equipment with internet viewing since 2015 for installation work and and switched to other brands. These includes brands which is used by Singapore Police/Cisco and is installed in various high security installation such as SMRT, Esplanade, etc.

For customers on maintenance contract, actions had been taken to secure their equipment from unauthorised access. This include replacing their AVTECH equipment with other brand/models. From our records, there’s no longer any customers who have AVTECH equipment installed by us which is under warranty as well.

If you are using AVTECH CCTV equipment, please contact your vendor to ask about security update patches/replacement options.

HiDDNS (Hikvision DDNS) Not Working – 2017-02-22

HiDDNS/Hikvision DDNS/ Problem

Currently at 22 Feb 2017 3.20pm ,

The system is currently back online.

We’ll continue to monitor it.

Currently at 22 Feb 2017 3.20pm ,

Free DDNS Services provided by Hikvision is not working.

If you have problem connecting remotely to your CCTV system, here are some temporary workaround.

Use Direct IP Connection

  • Get someone where the system is installed to visit
  • Take note of the IP displayed.
  • Change your Settings on your application to use the direct IP instead.

Here’s how to do it on your mobile app (iVMS-4500)

The CCTV system is still working and recording.
For customers on Dynamic IP plan from your ISP (Starhub/Singnet/M1), you are using the HiDDNS from HIKVISION to keep track of your current ip address.
As the HiDDNS Server is not working, you are unable to connect to your current IP from internet and therefore cannot connect to your CCTV System.

If you would like to reduce reliance on free manufacturer’s DDNS, you can consider the following

  1. Switch your internet plan to a Static IP Plan. Your IP will not change, and you can always use the IP to connect.
  2. Subscribe to alternative DDNS Services such as or These paid services have a higher SLA than free services provided by the manufacturer.

Manufacturer had already been notified. We’ll keep you updated.
