Deep dives
Privacy Headers and Bot Detection
The use of the sec-gpc header, designed to indicate privacy preferences, represents an attempt to improve upon the failed do not track header. Currently, this header is primarily utilized by Firefox, yet some bots are attempting to impersonate real browsers by using it, even when their user agents do not match. This discrepancy can expose the bots as non-legitimate browsers. Such header analysis may help web application firewalls reduce unwanted traffic to servers, although more advanced attackers can still easily mimic legitimate browsers.
Risks of Malicious Software Installations
The FBI has highlighted a rising trend in malware installations resulting from users downloading malicious file conversion software, emphasizing the importance of caution when searching for such applications online. Common search results may lead to harmful programs instead of legitimate converters, illustrating that even seemingly harmless software can pose significant risks. Recent incidents involving malicious Visual Studio Code extensions showcase the continued threat within even trusted software repositories. Users are advised to minimize installations and only download from reputable sources to mitigate these risks.
