Hikvision Blog Series Covers COVID-19 Vulnerabilities, Hacks, Phishing & Cyberattacks

 

Security magazine’s story, “New research shows significant increase in phishing attacks since the pandemic began straining corporate IT security teams,” covers new findings of an uptick in phishing hacks and vulnerability exploits.

The story covers research from the “2020 Phishing Attack Landscape Report,” conducted by news provider, Cybersecurity Insiders. The survey included more than 300 IT security professionals, and asked for personalized input related to their pandemic cybersecurity experiences.

Fifty-three percent of those surveyed confirmed seeing a rise in phishing attacks since the pandemic began.

From the article: “The survey revealed that, on average, organizations are remediating 1,185 phishing attacks every month. Even employees who are confident in their phishing identification skills are more likely to slip up when faced with a massive amount of malicious emails, and the impact of a successful attack is felt both monetarily and through time consumed by threat remediation.”

Hikvision’s senior director of cybersecurity wrote about coronavirus-related vulnerabilities, hacks and cyberattacks earlier this year. We compiled our 4-part blog series into one article with additional links to cybersecurity trends related to COVID-19, as well as tips to stay safe.

Check the HikWire blog tomorrow when we’ll cover part two of the Security magazine article and offer cybersecurity tips from Hikvision.

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

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.
