A Diary of mine was published today on the SANS Internet Storm Center. In this one, we delve into the support of HTTP and HTTPS among web servers on the internet, as well as support for Telnet and SSH, over the last six months.

After I finished the analysis of SSL/TLS configuration of almost 1400 internet banking portals (see the relevant ISC Diary, a question came to me. Internet banking portals should be among the best secured systems put online, yet not all of them made the mark when it came to encryption used to secure HTTP traffic. Would the situation be even worse for sites which are commonly assumed to lack proper security measures?

A Diary of mine was published today on the SANS Internet Storm Center. In this one we take a look at the use of TLS (and SSL) on banking sites all over the world.

The most important IT security-related news in July has definitely been the affair surrounding a theft of data from the Hacking Team – company, which develops commercial spyware intended for use by police departments and other security agencies. More than 400 GB of stolen data were made public and afterwards analyzed by IT security specialists, leading to discovery of a large number (still growing) of zero-day vulnerabilities which were used in Hacking Team’s products.

May has been at least as rich on cybersecurity incidents and events as any of the previous months of the year. Some of the more important are described in the following text. The VENOM (Virtual Environment Neglected Operations Manipulation) vulnerability may be considered to be a very significant one. VENOM is a vulnerability in the code of a virtual floppy drive which is used by some of the virtualization platforms (QEMU, KVM, Xen).

An international research team has devised attack called FREAK (Factoring attack on RSA Export Keys) with which it is possible to lower the level of encryption used in SSL connections. Attack is based on forcing server and client to use legacy (the vulnerability has been present for a long time) weak cryptographic suites which are still supported by some of the mainstream browsers (Safari and OpenSSL-based Android browser among others) and servers.
