HTTPS DROWN flaw: Security bods’ hearts sink as tatty protocols wash away web crypto • The Register

The discovery of a HTTPS encryption vulnerability, dubbed DROWN, again proves that supporting tired old protocols weakens modern crypto systems. DROWN (aka Decrypting RSA with Obsolete and Weakened eNcryption) is a serious design flaw that affects HTTPS websites and other network services that rely on SSL and TLS – which are core cryptographic protocols for

MS8209 teardown and repair

Mastech MS8209 is real multimeter that can measure almost anything. I have written some comments on Mastech MS8209 years ago. Some technical data on the back of the multimeter.

CacheBleed: A Timing Attack on OpenSSL Constant Time RSA

CacheBleed is a side-channel attack that exploits information leaks through cache-bank conflicts in Intel processors. By detecting cache-bank conflicts via minute timing variations, we are able to recover information about victim processes running on the same machine. Our attack is able to recover both 2048-bit and 4096-bit RSA secret keys from OpenSSL 1.0.2f running on
