Hikvision: Learn to Identify Phishing and Spear Phishing to Address Vulnerabilities


Social engineering is a trending security concern, with common attacks such as phishing and spear phishing growing rapidly. Security magazine covers this and other vulnerabilities and cybersecurity trends in the story, “Five cyber threats to watch in 2021.”

Microsoft reported that social engineering cyberattacks had grown to more than 20,000 per day in the U.S. alone. The article’s author describes social engineering as “a non-technical strategy that relies on human interaction and often involves deceiving people into breaching standard security practices, [that] will only increase in the new year.” It often involves common attacks such as phishing emails, which are fraudulent communications attempting to get a user to disclose confidential information or click a link that could install malware.

The Security magazine articles also touched on other trending security concerns, including the following:

  • Internet-Facing Vulnerabilities: This encompasses any system with an IP address and employees using a VPN (virtual private network). Cyber threat actors will deploy tactics that exploit “vulnerabilities in unpatched servers” using stolen credentials and other methods for hacking into systems.
  • Human-Operated Ransomware Attacks: Ransomware, a type of malware, can infiltrate networks via automated programs where threat actors send phishing emails to numerous targets at once, hoping for a successful breach. The article suggests that cybercriminals are taking a more sophisticated approach, using research to find tactics that will be most effective on the intended victim.

Learning to identify phishing and spear phishing can help you address vulnerabilities and reduce the likelihood you’ll become a victim of a cyberattack. Read the following Hikvision blogs to learn more:

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.
