  • Talking on Searchable Encryption at 32C3 in Hamburg, Germany

    This year again, I attended the Chaos Communication Congress. It’s a fabulous event. It has become much more popular than a couple of years ago. In fact, it’s so popular, that the tickets (probably ~12000, certainly over 9000) have been sold out a week or so after the sales opened. It’s gotten huge.

  • Things I learned from OpenSSH about reading very sensitive files

    You may have heard that OpenSSH had an exploitable issue with some bad client code (which is actually two CVEs, CVE-2016-0777 and CVE-2016-0778).

While the direct problem is basically the same as in Heartbleed, namely trusting an attacker-supplied length parameter and then sending back whatever happened to be sitting in memory, Qualys Security identified several issues that allowed private keys to leak through this issue despite OpenSSH's attempts to handle them securely. The specific issues are also fascinating in how they show just how hard it is to securely read sensitive files.

  • WhatsApp virus affects iOS and Android – and maybe more

    WhatsApp’s popular messaging app has been targeted yet again by cybercriminals – the latest attack affects both iOS and Android users.

    As part of a random phishing campaign, cybercriminals send fake emails represented as official WhatsApp content to spread malware when the 'message' is clicked on.

    The emails are being sent from a rogue email address, disguised with an umbrella branding “WhatsApp,” but if users look at the actual FROM email address, they will see it is not from the company.
