Thousands of WordPress sites backdoored with malicious code

by 1 Comment

Thousands of WordPress sites have been hacked and compromised with malicious code this month, according to security researchers at Sucuri and Malwarebytes.

All compromises seem to follow a similar pattern –to load malicious code from a known threat actor– although the entry vector for all these incidents appears to be different.

Researchers believe intruders are gaining access to these sites not by exploiting flaws in the WordPress CMS itself, but vulnerabilities in outdated themes and plugins.

 

When they gain access to a site, they plant a backdoor for future access and make modifications to the site’s code.

by 2 Comments

ewly identified WiFi attack called Wi-Jacking allow hackers to attack millions of WiFi network and accessing the neighbor’s WiFi without any form of Cracking.

few pre-requisites for this:

  • Client device MUST have previously connected to any other open network and allowed automatic reconnection
  • Client device SHOULD* be using a Chromium-based browser such as Chrome or Opera
  • Client device SHOULD** have the router admin interface credentials remembered by the browser
  • Target network’s router admin interface MUST be configured over unencrypted HTTP

Mitigations

  • Only login to your router using a separate browser or incognito session
  • Clear your browser’s saved passwords and don’t save credentials for unsecure HTTP pages
  • Delete saved open networks and don’t allow automatic reconnection
  • As it is nearby impossible to tell if this attack has already happened against your network, change your pre-shared keys and router admin credentials ASAP. Again, use a separate/private browser for the configuration and choose a strong key.

DEF CON 2018: Hacking Medical Protocols to Change Vital Signs

by 1 Comment

Doug McKee, senior security researcher at McAfee’s Advanced Threat Research team, has discovered a weakness that allows data on the patient’s condition to be modified by an attacker in real-time, to provide false information to medical personnel.

Medical devices use RWHAT protocol, to monitor a patient’s condition and vital signs. Using a small Raspberry device he could trick the nurse’s station monitor into thinking it’s communicating with something other than what it is.

The best defense for a hospital is to ensure that its networks are properly set up and isolated, and that devices are patched and that default passwords are changed.
