New Cryptowall 3.0 Ransomware Communicates over I2P Anonymous Network

We have seen a series of Ransomware tended to be simple with dogged determinations to extort money from victims. But with the exponential rise in the samples of Ransomware last year, we saw more subtle in design, including "Cryptolocker" that was taken down along with the "Gameover ZeuS" botnet...

Crowti Cryptowall 3.0 Ransomware Moving in I2P Network

A new strain of the Crowti ransomware, also dubbed Cryptowall 3.0, was spotted by researchers early this week after a quiet period during the holiday season. The twist to these recent infections is that the malware communicates over the I2P anonymity network. French researcher Kafeine confirmed...

OpenSSL RSA Temporary Key Cryptographic Downgrade Vulnerability

A vulnerability in OpenSSL could allow an unauthenticated, remote attacker to bypass security restrictions. The vulnerability is due to improper handling of an RSA temporary key. An attacker with a privileged network position could exploit the vulnerability by returning a weak temporary RSA key t...

Thunderstrike Apple Mac OS X Firmware Bootkit Unveiled

A vulnerability at the heart of Apple’s Mac OS X systems—one thus far only partially addressed by Apple—opens the door to the installation of malicious firmware bootkits that resist cleanup and give hackers persistent, stealthy control over a compromised Mac. The research is the work of a reverse...
