Name of the Vulnerable Software and Affected Versions Streetside Samourai Wallet version 0.99.96i

Description An issue in the PinEntryActivity.java file allows attackers to view sensitive information and decrypt data via a brute force attack using a recovered samourai.dat file. The PIN, which is 5 to 8 digits, may be insufficient to prevent such attacks.

Recommendations For version 0.99.96i, consider increasing the PIN length or implementing additional security measures to prevent brute force attacks. As a temporary workaround, restrict access to the samourai.dat file to minimize the risk of exploitation.
