WikiLeaks posts on the Internet an 88-gigabyte encrypted file labeled “WIKILEAKS INSURANCE,” along with the comment, “Protect our coming publications.” This is believed to be a “deadman’s switch,” meaning that unless WikiLeaks personnel are not there to periodically confirm their status, the file will be automatically decrypted, revealing its contents to those who have downloaded it. WikiLeaks have posted several similar files in previous years.
Heavy.com notes that because of recent comments by WikiLeaks head Julian Assange that the organization will soon be publishing more of Clinton’s emails, “many people are wondering if this insurance file is meant to ensure that WikiLeaks can release potentially damaging information about Hillary Clinton.” The file is large enough to contain millions of files if they are all text-based files, but it could include video or other files that take up much more space.
Heavy.com also notes that the reason WikiLeaks doesn’t simply post the files right away is, “The organization often combs through files to redact any sensitive information that might put lives in danger. The INSURANCE file is typically the unredacted version.” (Heavy.com, 6/17/2016)
