Hikvision Tips to Stay Safe from COVID-19 Related Vulnerabilities, Hacks & Cyberattacks


In yesterday’s HikWire blog, we covered new research findings that showed an uptick in phishing attacks since the pandemic hit earlier this year. The survey results were detailed in an article from Security magazine, with 53 percent of respondents seeing an increase in phishing attacks since the coronavirus pandemic began.

From the article: “Thirty-eight percent of respondents confirmed that a member of their organization had fallen victim to a phishing attack within the last year, and over a third (39 percent) feel that such an error reflects poorly on the victimized employee.” Research findings reinforce the need for employee cybersecurity training, added the article.

The survey found that 76 percent of companies conduct cybersecurity training, however 27 percent only conduct an annual training. To better improve identification of and response to phishing attacks, employees need additional training.

Phishing is the malicious use of social engineering to obtain sensitive information or access from an unsuspecting victim. This usually comes in the form of email, social media links, or other digital means that an attacker can use to trick a victim. Hikvision covered phishing basics and examples to help you identify phishing emails in this article.


Hikvision Tips to Stay Safe from Vulnerabilities & Cyberattacks
Hikvision’s 4-part blog series covered COVID-related vulnerabilities and cyberattacks, and can be found here. The article links to several blogs and offers tips to stay safe from our senior director of cybersecurity.

Phishing attacks grew exponentially beginning as early as February 2020, as outlined in this Hikvision blog.

Hikvision tips to prevent vulnerabilities and to boost cybersecurity include:

  • Create good, complex passwords.
  • Use a password manager to create and store those passwords so you don’t have to reuse them.
  • Enable Multi-Factor Authentication (MFA) everywhere you can to add another layer of protection when you log into websites and applications. Typically, we log into things with a username and password, however, there are three problems with this method:
  1. If a threat actor can get your password, they can access your account.
  2. Users tend to create easily-guessed passwords.
  3. Users tend to reuse passwords across multiple accounts, leaving them vulnerable to Credential Stuffing Attacks.

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.
