Password managers are still a good idea….but Google Project Zero finds a clickjacking vulnerability

LastPass has fixed a security bug that potentially allowed malicious websites to obtain the username and passphrase inserted by the password manager on the previously visited site.

Cryptocurrency-mining services exploiting Linux Skidmap Malware:

Trend Micro has observed that cybercriminals increasingly explored new platforms and ways to further cash in on their malware.  These include growing threats to mobile devices and Unix and Unix-like systems to servers and cloud environments.

Skidmap, a Linux malware, recently uncovered by Trend Micro, demonstrates the increasing complexity of recent cryptocurrency-mining threats. This malware is notable because of the way it loads malicious kernel modules to keep its cryptocurrency mining operations under the radar.  These kernel-mode rootkits are difficult to detect attackers can also use them to gain unfettered access to the affected system.
