  • [SingCERT] Alert on the Return Of Bleichenbacher's Oracle Threat (ROBOT) Attack 14 December 2017

    On 12 December 2017, a group of security researchers published findings that indicated that Transport Layer Security (TLS) implementation using RSA ciphers are vulnerable and may lead to information disclosure risk. TLS is a widely used internet security protocol that provides data privacy and integrity between two communicating applications (i.e. browser and Internet Banking website).

    This happens when applications with TLS implementation using RSA ciphers are subjected to adaptive-chosen-ciphertext attack. An attacker could send multiple selective ciphertexts to a victim for decryption. The results are then recorded and used to select subsequent ciphertexts, which will help to derive the TLS session keys. This vulnerability is named Return Of Bleichenbacher's Oracle Threat (ROBOT) Attack after Daniel Bleichenbacher who was the first person to discover this class of cryptosystem vulnerability 19 years ago (1998).

  • [SingCERT] Alert on HP Notebook Keylogger 12 December 2017

    A keylogger*-type feature was found in the Synaptics touchpad driver installed in several HP notebook models. Although this feature is disabled by default, an attacker with local administrative rights could still obtain the keystrokes by modifying the system to enable the keylogger feature on an affected notebook.

    *A keylogger is a type of surveillance technology used to monitor and record each keystroke typed on a specific computer’s keyboard.
