Facebook Login hijacking tool offered to black hat hackers

Penetration testing company Sakurity has openly named and blamed Facebook over a security vulnerability that it says exists on websites with a Facebook login option. Sakurity explains how to navigate around Facebook's JavaScript and existing login intelligence using a special redirect command. This will drive ‘victims' to a specified location where they are in fact logged into the Sakurity Facebook account. Sakurity then triggers the Facebook login that a user would expect on the client website so that its account is connected to the victim's account. Sakurity founder Egor Homakov says that from that point, Sakurity can log in that user's account directly to change email/password, cancel bookings, read private messages and so on. Read more...

EquationDrug: Sophisticated, stealthy data theft for over a decade

According to Kaspersky Lab researchers, The Equation Group uses expensive tools and sophisticated Trojans to steal data from their victims, and they also use "classic" spying techniques to deliver malicious payloads. Tools used by the group include EquationLaser, EquationDrug, DoubleFantasy, TripleFantasy, Fanny and GrayFish. The Equation Group" surpasses all others in complexity and techniques. Deemed the "ancestor" of Stuxnet and Flame, as Zero Days were used by The Equation Group before other threat actors -- and potentially shared by them -- additional details concerning the group's activities now suggest the group may have been in operation since the 1990's.

Security Awareness Tip

How to stop DDoS attacks

A denial of service (DoS) attack is an incident in which a user or organization is deprived of the services of a resource they would normally expect to have. Typically, the loss of service is the inability of a particular network service, such as e-mail, to be available or the temporary loss of all network connectivity and services...
There's no way to completely protect your network from denial-of-service attacks, especially with the prevalence of distributed denial-of-service (DDoS) attacks on the Internet today. It's extremely difficult to differentiate an attack request from a legitimate request because they often use the same protocols/ports and may resemble each other in content.
However, there are some things you can do to reduce your risk:

  • Purchase a lot of bandwidth. Is the easiest  but also the most expensive solution. It makes perpetrating a DoS attack much more difficult because it's more bandwidth that an attacker has to clog.
  • Use DoS attack detection technology. Intrusion prevention system and firewall manufacturers now offer DoS protection technologies that include signature detection and connection verification techniques to limit the success of DoS attacks.
  • Prepare for DoS response. The use of throttling and rate-limiting technologies can reduce the effects of a DoS attack. One such response mode stops all new inbound connections in the event of a DoS attack, allowing established connections and new outbound connections to continue.
