__link__ — Ids.xls

High risk of manual data corruption (e.g., accidental sorting of a single column that breaks ID alignments).

System administrators frequently write PowerShell, Python, or VBScript tools to audit active directory accounts. These scripts often generate a spreadsheet of user IDs that require termination or password resets, defaulting to a simple name like ids.xls . The Security Risks: Why ids.xls Can Be Dangerous

What (e.g., SQL Server, PostgreSQL, Salesforce) is importing the file? Roughly how many unique records do you need to sync? ids.xls

Although .xls files can contain VBA macros, attackers often rename malicious macro files to ids.xls to trick users. A phishing email with the subject "Updated ID List" and an attachment ids.xls is a classic social engineering tactic. Once the user enables macros, ransomware or keyloggers are deployed.

If the answer is no, you have just found your next security or compliance project. High risk of manual data corruption (e

This paper demonstrates that a simple statistical analysis of ids.xls can uncover meaningful intrusion patterns. The identified rules (ICMP size, RSTO flag, port 445 bursts) can be integrated into signature-based IDS rules (e.g., Snort). Future work should apply machine learning (Random Forest, XGBoost) to this dataset to improve classification accuracy.
