Hacking Challenge : Hack Tresorit and get $25,000 Bounty


Hungarian developers Istvan Lam and Szilveszter Szebeni are offering $25,000 Bounty to any White hat hackers who can hack the layers of defenses protecting their startup "Tresorit" , VentureBeat reports.

Tresorit is intended to offer a truly secure cloud storage service where user's files, passwords, encryption keys never stored in unencrypted form - being referred as high-security alternative to DropBox.

"Files and some corresponding encryption keys can only be decrypted by the people you have explicitly shared with."

The site offers client-side encryption in which the encryption of files is performed before getting into the cloud.  The AES-256 standard is used for encrypting the files.

"All of our data centers employ physical security measures against intrusion, and are equipped with uninterruptible power and backup systems."

$1 Million reward for Hacker who exploiting Google chrome

Google has pledged cash prizes totaling $ million to hacker who successfully exploit the chrome browser next week's CanSecWest security conference. In fact, Chrome is the only browser in the contest's six year history to not be exploited.

Google will reward winning contestants with prizes of $60,000, $40,000, and $20,000 depending on the severity of the exploits they demonstrate on Windows 7 machines running the browser.  Members of the company's security team announced the Pwnium contest on their blog on Monday.

There is no splitting of winnings, and prizes will be awarded on a first-come-first-served basis until the $1 million threshold is reached.

All winners will also receive a Chromebook.

"While we're proud of Chrome's leading track record in past competitions, the fact is that not receiving exploits means that it's harder to learn and improve," wrote members of the Google Chrome security team in a post on Monday. "To maximize our chances of receiving exploits this year, we've upped the ante. We will directly sponsor up to $1 million worth of rewards."

In the blog post, the researchers said Google was withdrawing as a sponsor of the Pwn2Own contest after discovering rule changes allowing hackers to collect prizes without always revealing the full details of the vulnerabilities to browser makers.
