Cisco Systems has released a security update that closes a backdoor allowing attackers to control software that large organizations use to manage voice over IP (VoIP) calls and messaging over their networks.
Researchers have warned of a vulnerability present on an estimated 86 percent of Android phones that may allow attackers to obtain highly sensitive credentials, including cryptographic keys for some banking services and virtual private networks, and PINs or patterns used to unlock vulnerable devices.
The ransomware model is increasingly being adopted by cybercriminals who target mobile users, one of their latest creations being able to encrypt files stored on the SD memory cards of Android devices.
A new threat dubbed Android/Simplock.A was identified by researchers from antivirus firm ESET over the weekend and while it’s not the first ransomware program for Android, it is the first one seen by the company that holds files hostage by encrypting them.
A group of developers has decided to continue supporting free encryption tool TrueCrypt which appeared to have suddenly closed its doors last week, leaving customers angry and confused.
A new website has been created at truecrypt.ch where Thomas Bruderer and Joseph Doekbrijder are co-ordinating efforts to make existing versions of the product available again and eventually to fork the code for future development.
Crypto researchers are preparing to scatter the ashes of a class of Discrete Logarithm Problems (DLPs) as the future of security, following a claim by Swiss researchers to have cracked a 128-bit crypto scheme in two hours.
So as not to frighten the horses, The Register will start by pointing out that our understanding of this paper at Arxiv doesn't mean the schemes you're now using have been broken. Rather, the work by researchers at EPFL in Switzerland excludes crypto based on “supersingular curves” from future consideration.
