Police Say They Can Crack BlackBerry PGP Encrypted Email (sophos.com) 117

Posted by Soulskill from the proof-is-in-the-pgpudding dept.
schwit1 writes: Police in two countries have claimed that they can read encrypted data from BlackBerry devices that are being marketed as having "military-grade security." The story originally broke when Dutch website Misdaadnieuws (Crime News) published documents from the Netherlands Forensic Institute (NFI), a Dutch law enforcement agency, stating that police were able to access deleted messages and read encrypted emails on so-called BlackBerry PGP devices. A representative from NFI confirmed that "we are capable of obtaining encrypted data from BlackBerry PGP devices," according to a report from Motherboard. On Tuesday, the Royal Canadian Mounted Police (RCMP) also told Motherboard they can crack encrypted messages on PGP BlackBerrys.

      It wouldn't surprise me if the app saves the plaintext somewhere on the filesystem, creates an encrypted copy for mailing, and then just does a soft delete. With SSD/Flash memory write algorithms, it could be a very long time before that gets overwritten.

      • Yeah I'd bet the code looks like this:
        save(msg, temp_file)
        encrypt(temp_file, encrypted)
        mail(encrypted)
        delete(temp_file)

        Retrieving the plaintext is therefore a matter of recovering the deleted temporary file.

        Incorrect. At least with SSDs (also flash memory), you cannot overwrite an existing block, it has to be erased first. To make sure writes are speedy, the firmware normally actually clear blocks immediately or are queued for rapid deletion during idle time when a file is deleted. This is in contrast to a spinning disk where the entry in the file table is deleted but the blocks remain to be overwritten (or recovered) later.

        See: http://www.forensicmag.com/art... [forensicmag.com]

        • You are correct. However, you have no idea what the firmware behavior is. For example, if the SSD is 80% unused, does it need to clear blocks? What is the logic for determining "idle time"? Is the SSD file system aware? (i.e. - Does the OS have to trigger the trim, or does the drive have enough intelligence to do it without the OS?) Also, just for fun, remember that there are people who have phones that are 5+ years old, and may use antiquated techniques for determining their behavior.

          Since written pages are part of larger blocks which have to be erased all at once, a page with discarded data may exist without being erased until either all of the pages in the block are discarded and the block is erased or used pages are copied to a new block and the old block is erased. Individual pages cannot be erased.

      • Even with a "hard" delete, the data can likely still be there. Especially with SSD and flash, and their wear levelling algorithms, where a sector erased and written may not be the same sector that had data on it. In theory, a TRIM should blow that away, but it may be a while before the drive's garbage collector goes and erases those pages. It would be nice to have a "secure wipe these pages now" function in the command set.
