ROBOT Attack

ROBOT Attack
15 December, 2017 Gonçalo Alberto

On 12 December 2017, a research paper entitled “Return of Bleichenbacher’s Oracle Threat” (ROBOT) was made publicly available. ROBOT is the return of a 19-year-old vulnerability which, under some circumstances, may allow for traffic decryption and server identity theft (websites).

Affected systems:
To date, vulnerable implementations from Cisco, Citrix, F5, Oracle, Radware and open-source projects, such as Bouncy Castle, Erlang and WolfSSL, have already been identified.

Researchers have also examined Alexa’s top 100 domains and concluded that 27 of those subdomains host vulnerable websites, including popular websites, such as Facebook and Paypal.

To check whether your system has been affected, take this simple test:



  • Carry out a vulnerability analysis;
  • Disable TLS RSA cyphers;
  • Apply safety patches and other specific recommendations from manufacturers.
