Microsoft Excel Working With Linked Worksheets

Published

on

Microsoft Excel provides several methods for linking values across worksheets or across workbooks. Which method you choose will depend on your desired end result. This article will review the pros and cons of each method.

Linking by creating a formula. With this method you can create an inter-active link between worksheets or workbooks. The linked cells do not need to be in the same location on all worksheets. You can perform any math operation while creating the link. For example, you could take a figure from one worksheet, multiply it times a figure form another worksheet and then subtract a number from a third worksheet. You can use this method to link cells across worksheets or workbooks. One disadvantage of this method is that it is time consuming because you are working with one cell at a time. Using named ranges can assist with this method of linking and make it easier to read your formulas once they are created.

Creating a Sum across worksheets. This is also an inter-active link. If a number changes on one worksheet, the sheet with the summary formula will also be updated. If a worksheet is inserted between worksheets in the sum, the sum will automatically be updated. Some of the disadvantages of this method are that all of the linked cells must be in the same location on all worksheets. Also, you can only sum one cell at a time (although you can copy the formula to other cells in the summary worksheet.) Using group mode to create identical spreadsheets will help when using the sum function across worksheets. This method is also limited to within a workbook and cannot be done across workbooks.

Using the Consolidation feature. You can determine whether or not the link will be interactive when creating the consolidation. This method provides the greatest level of detail in the summary worksheet. You can choose between any function, not just the sum function. For example, you could create an average of several divisions in a summary worksheet. Some of the disadvantages of this method are that the worksheets must be identical. Although it is not impossible, it is difficult to use consolidation across workbooks.

Using Paste Link. This also creates an inter-active link. The linked cells do not need to be in the same location on all worksheets. You can link between worksheets or workbooks. This is a great way to link totals from one worksheet to another, however, you do not have the detail that is provided by Consolidation.

Chinese Hackers Using Log4Shell Exploit Tools to Perform Post-Exploitation Attacks

The cybersecurity firm, CrowdStrike has warned that Chinese hackers are using the Log4Shell exploit tools to perform various post-exploitation operations.

The hacker group behind these malicious operations, Aquatic Panda was seen using the Log4Shell vulnerability, with the help of a large academic institution.

In early December the Log4Shell and LogJam vulnerability, which were tracked as CVE-2021-44228 was discovered in the popular Log4j logging library.

Aquatic Panda

Aquatic Panda is a Chinese hacking group that is operating since May 2020 and it has two primary goals:-

  • Intelligence collection.
  • Industrial espionage.

This hacking group mainly targets all its users from the following sectors:-

  • Telecommunications sectors
  • Technology sectors
  • Government sectors

Apart from this, the AQUATIC PANDA counts on the following tools for the execution of all its operations:-

  • Cobalt Strike
  • FishMaster (Unique Cobalt Strike downloader.)
  • njRAT

Technical Analysis

To gain initial access to the target system, the Aquatic Panda uses a modified version of the exploit for a bug in Log4j, and then it performs several post-exploitation activities like:-

  • Exploration
  • Credential collection

The hackers targeted VMware Horizon that used the vulnerable Log4j library to compromise a large academic institution, and on December 13, 2021, the exploit used in this attack was published on GitHub.

On the Windows host where the Apache Tomcat service was running, the team ran a series of Linux commands, and not only that even they also performed the same on those aimed at deploying malicious tools that are hosted on remote infrastructure.

Here at this point to better understand privilege levels and learn more about the domain, the threat actors have also conducted surveillance efforts. While they also tried to interrupt a response solution and third-party endpoint threat detection solution.

The malware and three VBS files were extracted by the hackers through PowerShell commands, and to accomplish this, additional scripts were deployed by the hackers.

At this stage, by performing memory dumps and preparing them for theft, the threat actors of Aquatic Panda attempted several trials to collect credentials.

Moreover, the attacked academic institution was timely warned of suspicious activities to be able to quickly use the incident response protocol, fixing vulnerable software and deterring further development of the malicious activity.
