Why are Flash Cookies Harmful?
- they are never expiring – staying on your computer for an unlimited time.
- by default they offer a storage of 100 KB (compare: Usual cookies 4 KB).
- browsers are not aware of those cookies, LSO’s usually cannot be removed by browsers.
- via Flash they can access and store highly specific personal and technical information (system, user name, .).
- ability to send the stored information to the appropriate server, without user’s permission.
- flash applications do not need to be visible to the user
- there is no easy way to tell which flash-cookie sites are tracking you.
- shared folders allow cross-browser tracking, all browsers use the same LSO folder
- the company doesn’t provide a user-friendly way to manage LSO’s, in fact it’s incredible cumbersome.
- many domains and tracking companies make extensive use of flash-cookies.
- flash-cookies are used to re-create data of deleted traditional cookies.

Hushmail, a Canadian company providing email security using PGP, has released to the US government unencrypted email communications. This respresents a violation of users’ trust in the company. I had an account with them, I will delete all my mail, and close that account. I will only trust my own computer for safe email sending/receiving. No longer will I trust the ‘security’ and ‘privacy’ of a third-party.
The DEA agents received three CDs which contained decrypted emails for the targets of the investigation that had been decrypted as part of a mutual legal assistance treaty between the United States and Canada.
The news will be embarrassing to the company, which has made much of its ability to ensure that emails are not read by the authorities.
Typically, when you ‘delete’ a file, you are only detaching the link from your filesystem to the actually binary data on the physical platters of your hard drive. The data aren’t really gone. The filesystem declares this space as ‘free’ or ‘available’, and so only goes away when that space is overwritten by new data.
If you’ve ever desire to truly delete a file, then download file shredder. It allows you you select and right click any file, and it automatically overrights them with random data, stuffs it full of zeros, and then deletes it. This prevents anyone from ever recovering that file with forensic software. Larger files take longer to shred, but are usually shredded in under 1 minute. If I coulf find the author’s email, I’d ask him/her to add a right-click to “shred all files in the recycle bin.”
