Hikvision Cybersecurity Director on How Attackers Access Your Accounts Using Credential Stuffing, and Three Tips to Address this Security Concern

Hikvision HikWire blog article Cybersecurity Director Attackers Access Accounts Credential Stuffing, Three Tips Address Security Concern

Our previous Hikvision blog discussed using multi-factor authentication (MFA) to reduce security concerns and outlined a number of tips to implement MFA for better cybersecurity.

An excerpt from that blog: “MFA adds two or more pieces of verifiable evidence or factors to the authentication process to greatly reduce security concerns by lowering the chances of an account being accessed by the wrong person. Two-factor authentication (2FA) is a subset of MFA and is a means of authenticating with just two pieces of verifiable evidence or factors. A good real-world example of 2FA is using an ATM. You use something you have, the ATM card, and something you know, your pin number.”

In this blog, we’ll discuss credential stuffing—what it is and how to avoid being a victim of it.  

What is Credential Stuffing?
Almost every day we see headlines about some sort of data security breach. The public is now almost numb to this news and the reaction by the end users whose credentials were lost is typically to reset their password and move on.

This is likely not good enough for most people because, according to a January 2019 study by Yubico and Ponemon, 51 percent of the respondents reuse their passwords across multiple accounts.

So why is it bad to reuse passwords across multiple accounts? Because bad guys will take that long list of usernames and passwords from data security breaches, and use them in an attack called credential stuffing. I know, this sounds like a bad Thanksgiving side dish full of conference badges … it’s worse!

Credential stuffing is when an attacker takes a long list of usernames and passwords and, using an automated script, tries each pair on many popular websites. Those sites could be business or email related, like Google, Apple, and Microsoft. They could be social media accounts like Facebook, LinkedIn, and Instagram, shopping accounts like Amazon or any other popular sites, like banks and payment tools such as Venmo.

Three Tips from Hikvision to Prevent Credential Stuffing
Once the automated script is successful at logging into a site, that username and password pair is saved for later review and use by the attacker against other sites. So let’s walk through an example. Let’s assume that Bob reuses passwords across many of his accounts. He has a password for work accounts and a separate one for social media accounts. After the LinkedIn security breach a few years ago, Bob’s username and password were made public when miscreants posted the list of breached account credentials to the Internet.

A threat actor, named Mary, decided to take that list and run it through her credential stuffing script. Once the script completed its test, Mary found out that Bob had reset his LinkedIn password, as instructed, but was still using the same password for Facebook and Twitter. Since Bob isn’t using multi-factor authentication on those sites, Mary was able to successfully log into and take over, or even just watch, Bob’s social media accounts.

This is a common attack method and underscores the need for everyone to follow good cybersecurity practices. Below are three ways to avoid being in Bob’s position:

By following these three tips, you will reduce the likelihood of becoming an easy target of 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

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.

K-Series DVR upgrade instruction
The Turbo 4 Hybrid DVR K series has multiple models and across different platform and chipset. It also has similar firmware development of other recording product line; DVR K series has also introduced the GUI4.0 to ensure the series to be compatible to the newest technology available. The new database architecture is also brought into the DVR firmware v4.0 to be future proof and for better recording search experience. 
 


Database Optimization and Repair

As more affordable cameras 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 optimize. If you are experiencing issues, where playback is expected but not found, please make sure to perform "Database Rebuild" as indicated in the procedures and scenarios below.
 


Preparing the Upgrade

Before proceeding with upgrade, it is recommend exporting DVR configuration file from the DVR over the network or on to a local USB drive.

 

Action after firmware upgraded 

1. Upgrade the DVR according to the chart above. 

2. Reconfirming Channel's Recording Schedule 

    - Confirm channel's recording schedule is enable. 

    - Check if the channel is on correct recording schedule.

3. Double Check Storage Setting

    - Make sure all channel are assigned to record on its HDD group when the Storage setting is under Group Mode. 

4. Perform Database Rebuild locally. 

    • Some version above support Database Rebuild via web access - K51 and K72

    • Perform Database Rebuild regardless if system is having any database issue symptom. 

    • Database Rebuild process is average ~30 to 60min per TB. The process may still varies depends recording data.

    • After Database Rebuild - Check log to confirm Database Rebuild has went thru properly. 

    • If Database Rebuild Started and Stopped log has been log only within few minutes. Database rebuild may not has been completed properly. It is strongly recommend performing the Database Rebuild again.

    • To check log > System > Log > Information > Database Rebuild Started and Stopped.

    • If the log option is not available - access system via SSH can also obtain similar result.

5. Recording Data is still missing after database rebuild process. 

If the data has not been recorded or has been overwritten, Database rebuild process is not able retrieve those lost data. Have the system upgraded to the latest available firmware version above to prevent any future data lost is strongly recommended for all application.
