Hikvision Cybersecurity Director Outlines Tips to Identify and Prevent Phishing and Spear Phishing, Malware


In the article, “Hackers refine, improve their phishing skills,” editorJoel Griffin states that hackers have become more adept at carrying out targeted cyberattacks as security breach proliferates.

From the article: “While popular culture might lead you to believe that today’s hackers are computer geniuses with intimate knowledge of network architectures who go about their days working in a dark, shadowy underworld clothed in hooded sweatshirts, the reality is much different. … These fraudsters typically employ what are commonly known as phishing scams, which involve crafting an email in a way that seems to the average user like it is coming from a credible entity, such as a bank or an employer, but in actuality is a scam designed to dupe the victim into unknowingly turn over confidential information or click on a link that downloads a malicious link onto their desktop or mobile device. Some of these schemes even include highly detailed information about the recipient and/or people they know in much more targeted attacks known as spear phishing attacks.”

Phishing attacks are increasing, and messaging security provider Cloudmark found that an average phishing attacks costs a mid-sized company about $1.6 million to resolve, according to the article.

Griffin suggests that organizations provide comprehensive cyber training for their employees so they can recognize, and avoid becoming a victim, of phishing emails.

“Organizations have to continue to up their vigilance, continue to educate their employees, but they also need some protections in place around things like filtering emails and protections to make sure if someone tries to visit a site that is a known phishing link that they have some blocks in place to prevent employees from hurting themselves or the business,” said Mike Gross, head of global fraud & ID product innovation at Experian, in the article.

Tips to Identify Phishing and Spear Phishing

To reduce security concerns, Hikvision’s cybersecurity director Chuck Davis authored several blogs on how to identify phishing and spear phishing emails to avoid becoming a victim of them.

In the article, “Cybersecurity in the Workplace: Hikvision Cybersecurity Director Discusses Spear Phishing,” Davis outlines nine steps phishing victims can take to be proactive about the threat. Below are a few of the article’s tips:

  • If this is a business email address, let your cybersecurity team know immediately about the threatening email. There could be an ongoing company-wide campaign that the cybersecurity team can stop. If the cybersecurity team is aware of the campaign they can also help educate employees.
  • Use two-factor authentication (2FA) or multi-factor authentication (MFA) everywhere possible.
  • Use a password manager. This will allow you to make great passwords (20 plus characters) that are unique for every website. And, you won’t need to remember any of them.

Davis also wrote a two-part blog on examples of phishing, where he said: “Phishing attacks have long been an effective way for attackers to trick people into divulging sensitive information or infecting a system with malware. Malware can give an attacker remote access to protected systems and networks, encrypt a user’s data and charge a ransom to decrypt the data, or use that system as part of an attack against other systems.” Read part one on phishing here, and part two at this link.

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.
