CSRF tokens are random values that are generated by the server and included in requests that perform state-changing actions. They are used to prevent CSRF attacks by verifying that the request originates from a legitimate source. However, if the CSRF tokens are transmitted using cookies, they are vulnerable to being stolen or forged by an attacker who can exploit other vulnerabilities, such as cross-site scripting (XSS) or cookie injection. Therefore, a better option is to avoid the transmission of CSRF tokens using cookies and use other methods, such as hidden form fields or custom HTTP headers.

Enabling the browser’s XSS filter would be the most likely solution to the listed vulnerability. The vulnerability is a reflected cross-site scripting (XSS) attack, which occurs when a malicious script is injected into a web page that reflects user input back to the browser without proper validation or encoding. The malicious script can then execute in the browser and perform various actions, such as stealing cookies, redirecting to malicious sites, or displaying fake content2. Enabling the browser’s XSS filter can help prevent reflected XSS attacks by detecting and blocking malicious scripts before they execute in the browser3.

Documenting the chain of custody is an important step in the forensic analysis of any device, as it helps to ensure that all evidence is collected and preserved correctly. A memory dump is also essential, as it can provide information about the state of the device when the attack occurred and can be used for further analysis.

Documenting the respective chain of custody can help to preserve the integrity and admissibility of the evidence collected from the mobile device during the forensic analysis. Chain of custody is a record of who handled, accessed or modified the evidence, when, where, how and why . Performing a memory dump of the mobile device for analysis can help to extract volatile data from the mobile device that may contain valuable information about the ransomware attack, such as processes, network connections or encryption keys. Memory dump is a process of copying the contents of the memory (RAM) to a file or storage device .
