1-15 August 2013 Cyber Attacks Timeline

August 19, 2013 Leave a comment

The first half of August has gone, so it is time for the Cyber Attacks Timeline summarizing the main events occurred in this period.

Looks like the massive breaches have decided to have a break during August. Although the first fifteen days have shown a remarkable number of attacks, no huge leaks have been recorded.

The only exception is the latest attack to the United States Department of Energy (14,000 individuals potentially affected) and the one targeting the Ferris State University with nearly 60,000 records potentially affected.

Other remarkable events include the attacks against Opscode and Crytek. In this latter case four websites have been temporarily taken down.

Last but not least, the Syrian Electronic Army is back in action, and its wave of Social Engineering attack has directly and indirectly hit many primary targets such as Channel 4 and the New York Post (via the hack to the SocialFlow platform).

Important: this period has also seen an high cyber activity between India and Pakistan. The attacks deserve a dedicated timeline to be published very soon. So they will not appear in this timeline.

As usual, if you want to have an idea of how fragile our data are inside the cyberspace, have a look at the timelines of the main Cyber Attacks in 2011, 2012 and now 2013 (regularly updated). You may also want to have a look at the Cyber Attack Statistics, and follow @paulsparrows on Twitter for the latest updates.

Also, feel free to submit remarkable incidents that in your opinion deserve to be included in the timelines (and charts).

The Next Step of Botnets

September 15, 2012 Leave a comment

A BlackHole (Exploit Kit) absorbing an Onion (Ring), the future of Botnets?

This information security week has offered many interesting points: the brand new CRIME attack against SSL/TLS, the release of BlackHole Exploit Kit 2.0 that promises new stealth vectors of Drive-By download infections, the takedown of the emerging Nitol botnet by Microsoft, and, last but not least, the first (?) known example of a new generation of a C&C Server leveraging the anonymization granted by Tor Service.

The latter is in my opinion the news with the most important consequences for the Information Security community, since delineates the next step of Botnets’ evolution, after the common, consolidated, C&C communication schema, and its natural evolution consisting in Peer-to-Peer (P2P) communication.

The first (I wonder if it is really the first) discovery of a Botnet command server hidden in Tor, using IRC protocol to communicates with its zombies,  has been announced in a blog post by G-Data. Of course the advantages of such a similar communication schema are quite simple: the Botnet may use the anonymity granted by the Deep Web to prevent the identification and the likely takedown of the server, and the encryption of the Tor protocol to make traffic identification harder by traditional layers of defense. Two advantages that greatly exceed the Tor latency which represents the weakness of this communication schema.

Maybe it was only a matter of time, in any case it is not a coincidence that in the same weeks researchers have discovered BlackHole 2.0 and the first (maybe) C&C infrastructure hidden inside the Deep Web: Cyber Criminals are continuously developing increasingly sophisticated methods to elude law enforcement agencies and to evade the security controls of the traditional bastions, and the botnets are confirming more than ever to be the modern biblical plague for the Web…

And even if every now and then good guys are able to obtain a victory (as the Nitol takedown), the war is far from over.

Imperfect Cybercrimes

April 19, 2012 1 comment

Law Enforcement Agencies are taking their revenge against the Hacktivists who mostly targeted them during the last months. In a deadly and unexpected sequence, the last 40 days have seen the heads of three infamous hacking crews falling under the blows of FBI and Scotland Yard.

One after the other, the key members of LulzSec, CabinCr3w and Team Poison have been arrested and in all but one case (that is the arrest of the alleged members of Team P0ison for which no details are known so far), the events have unveiled some surprises and unexpected details. Moreover, at least three arrests have been possible since the hackers left behind them a trail of mistakes which allowed the investigators to connect the dots and link their twitter accounts to their real identities.

The following table depicts the facts which may be better summarized from the Criminal Complaints which are reported below for:

As you may notice, in two cases, W0rmer and ItsKahuna, the hackers were betrayed by two familiar technologies which are commonly considered dangerous for users’ privacy and identity: social networks and mobile devices. Sabu was the one who really did a “technical mistake” by connecting to an IRC without protecting his IP address with TOR.

Interesting to say is also the different approach of FBI and Scotland Yard. Once discovered the real identities of the hackers the Feds tried to “enroll” them as informants, at least in one case (Sabu) this strategy was winning. At the opposite the Britons immediately caught the alleged culprits without giving any detail about their identity, maybe hoping the arrest could act as a deterrent for the other hackers. Apparently it looks like this latter strategy was not completely successful since the CabinCr3w survivors are threatening authorities, inviting other Blackhats to join them for the revenge.

Last but not least, I cannot help but notice the tweet below for which I remember to have been particularly impressed when I first saw it since, at that time, I considered it a too much imprudent. Consequently I was not that surprised when I saw it quoted in the Criminal Complaint.

At the end we are becoming more and more familiar with mobile phones and Social Network, so familiar to forget their level of intrusiveness and the related dangers for our privacy. As an example try to verify how many of you and your friend toggle Geo-Tagging off from their phone cameras. (Un)fortunately, it looks like not even the bad guys are immune from this.
