RACCOON ATTACK : A Timing Attack to Leak Secret Keys

Abstract

In today’s socio-economic atmosphere one of the firmest developing areas of technical infrastructure development is the Internet. The aggregate cyber-attacks over the past decade are posing a thoughtful threat to the digital world. The paper centers around the Raccoon: The Story of a Typical Information stealer. Raccoon stealer was found in April 2o19. Raccoon is a mainstream information stealer these days on account of its low value (USD$75 every week and $2oo every month) and its rich highlights. Otherwise called "Racealer, "Racoon is used to steal sensitive and personal data which includes login credentials, credit card data, cryptocurrency wallets and browser data (cookies, history, autofill) from very nearly 6o applications. “Raccoon,” the attack has been described as complex and the vulnerability is “very hard to exploit.” While most clients ought to presumably not be worried about Raccoon, a few significant programming merchants have delivered patches and mitigations to ensure customers. Raccoon can permit a man-in-the-middle (MitM) attacker to break encrypted communications that could contain delicate data. However, the attack is only successful if the targeted server reuses public Diffie- Hellman (DH) keys in the TLS handshake (i.e. the server uses static or ephemeral cipher suites such as TLS-DH or TLS-DHE), and if the attacker can conduct precise timing measurements.
