SC Magazine Explores New Vulnerabilities and Changes in the Cybersecurity Landscape Since Onset of Pandemic

Hikvision Covers COVID-Related Vulnerabilities, Plus Tips to Work Safely from Home


The SC Magazine story, “The pandemic brings new risk, even as nature of cyber threats remain pretty familiar,” explores how the cybersecurity landscape has changed, and threat actors have taken advantage of new vulnerabilities, since the pandemic has transformed work patterns. 

From the article: “In August, Microsoft released the results of a sprawling survey of 800 business leaders in the U.S., United Kingdom, India and Germany to determine how the pandemic was affecting their cybersecurity priorities. The data shows that ‘an alarming number of businesses’ are still impacted by rudimentary phishing scams, security budgets and hiring needs. The top five investments since the virus struck are multi-factor authentication tools, endpoint device protections, anti-phishing tools, VPNs and end user security education.”

While many of hacker tactics remain similar to previous years, threat actors are taking advantage of the increase in remote workers to exploit vulnerabilities. In addition to growth of existing tactics such as phishing, older vulnerabilities are also on the rise, according to the SC Magazine article.

And, Hikvision noted in an April 2020 blog that “Barracuda Networks researchers have seen a steady increase in COVID-19 coronavirus-driven phishing attacks, and since the end of February 2020 they found a 667 percent rise in these attacks.” To learn more about COVID-19 phishing scams and other attacks, read this Hikvision blog that covers our coronavirus cyber series: “Hikvision Blog Series: Senior Cybersecurity Director on COVID-19 Hacks, Phishing & Cyberattacks.”

One tip to work safely from home and reduce vulnerabilities is to use your company virtual private network (VPN). The VPN ensures that all of your work traffic, and likely all of your network traffic, goes through the company network before it gets to the Internet.

IMPORTANT! This model requires non-standard firmware. Do Not Install standard firmware (e.g. v.4.1.xx) on this model. Doing so will permanently damage your system. You must use custom firmware v.4.1.25 from the iDS-9632NXI-I8/16S product page.

The I-series NVR (such as the DS-7716NI-I4) is one of Hikvision's most popular and feature-rich recorders. As such, many firmware revisions have been introduced over the years to continually ensure the product is compatible with the newest technology available. Due to the many revisions, we recommend that the user closely follows the instructions below in order to reduce the amount of time spent as well as the chance of failure.


Database Optimization and Repair

As more affordable IP cameras are introduced over time with greater video resolution and data sizes, more efficient database management also becomes necessary. The introduction of firmware v4.0 brought about a new database architecture in order to be futureproof.


After upgrading to v4.X, the recorder database will need to be converted and optimized. If you are experiencing issues where playback is expected but not found, make sure "Database Repair" is performed as indicated in the procedures and scenarios below.


Preparing the Upgrade

Before proceeding with upgrade, it is recommended that NVR configuration file is exported from the NVR over the network or on to a local USB drive.


Upgrading from v3.4.92 build 170518 or Older

  1. All recorders must reach v3.4.92 before proceeding further. Upgrading from versions before v3.4.92 directly to any version of v4.X will likely cause the recorder to fail.
  2. If the recorder is already at v3.4.92, a full factory default is highly recommended before upgrading to any version of v4.X. There is a high chance of unit failure (requiring RMA) if the unit is not defaulted before upgrade.
  3. After reaching v3.4.92 and performing a full factory default, an upgrade directly to v4.50.00 is acceptable.
  4. After the upgrade is completed and the recorder is reprogrammed, it may be beneficial to perform a Database Repair. For details, refer to the section "Database Optimization and Repair" above.
  5. To verify repair progress, you may refer to the HDD status, or search the recorder log for repair started and stopped entries. Note that while the HDD is repairing, new recordings are still being made, but some existing recordings may not be searchable until repair is complete.
  6. If you continue to observe playback issues after database repair, ensure there are no power, network, or motion detection issues. Should the problem persist, contact technical support.


Upgrading from Any v4.X Build to v4.50.00.

  1. Any v4.X build can be upgraded directly to v4.50.00.
  2. Export configuration is highly recommended before performing the upgrade.
  3. If upgrading from any v4.X version that was not v4.22.005, a Database Repair is recommended. Refer to Step 4 and onwards in the previous section.



Downgrading is not recommended. Due to new features and parameters constantly being added, downgrading may cause the NVR to factory default itself or require a manual default to operate properly.
