Hikvision on Phishing Examples, and Tips to Avoid this Malicious Hack

 

An abundance of caution is causing some employees to avoid opening certain emails, fearing they might be a security concern such as phishing. Covering this challenge, and offering ways for employees to identify real correspondence versus malicious hacks, is the SC magazine article, “Phishing fears cause workers to reject genuine business communications.”

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. Read more about phishing here.

From the SC article: “The problem is that real communications and fake ones are getting harder to distinguish from each other. Attackers use current events as a trigger for people to engage, which has indeed led to a scourge of COVID-themed phishing scams since the pandemic started. Recipients are flooded with lures related to coronavirus maps, vaccines and, yes, contact tracing, to trick people.”

The article noted that unsolicited emails often appear to use the same tactics cybercriminals employ with phishing.

To combat this challenge, organizations can implement “domain-based message authentication,” which helps to prevent company domains from being spoofed and used in phishing attacks. To ensure messages are opened and read, remove attachments and links in an email such as company communication. Instead, place the content as text in the body of the email.

Learn more about phishing hacks in this Hikvision blog. And, read “Examples of Phishing, Part 2,” which offers several tips to prevent becoming a victim to phishing. Some of the tips include:

  1. Filter spam.
  2. Be wary of unsolicited email.
  3. Treat email attachments with caution.
  4. Don’t click links in email messages.

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.
