Christmas has just gone and here it is my personal way to wish you a Happy New Year: the second part of my personal chart (first part here) of Main 2011 Cyber Attacks covering the time window from August to November 2011 (December is not yet finished, and featuring remarkable events, so expect an update very soon). This memorable year is nearly over and is time, if you feel nostalgic, to scroll down the second part of the list to review the main Cyber Events that contributed, in my opinion, to change the landscape and the rules of the (information security) game. Many events in this period among whom, IMHO, the most noticeable is the one carried on against Diginotar. Since then our trust in conventional authentication models is not (and will not be) the same anymore.
Of course this is my personal selection. Suggestions are well accepted and if you need more details about the cyber events in 2011, feel free to consult my 2011 Cyber Attacks Master Index. As usual after the page break you find all the references…
This year is nearly at the end but it looks like it is really endless, at least from an Information Security Perspective. As a matter of fact this 2011 will leave an heavy and embarassing heritage to Information Security: the Certification Authority authentication model, which has been continuously under siege in this troubled year; a siege that seems endless and which has shown its ultimate expression on the alleged compromise of yet another Dutch Certification Authority: Gemnet.
Gemnet, an affiliate of KPN, has suspended certificate signing operation after an intrusion on its publicly accessible instance of phpMyAdmin (a web interface for managing SQL Database) which was, against any acceptable best practice, exposed on the Internet and not protected by password. As in case of Diginotar, another Dutch Certification Authority which declared Bankrupt few days after being compromised by the infamous Comodo Hacker, Gamnet has the Dutch government among its customers including the Ministry of Security and Justice, Bank of Dutch Municipalities and the police.
After the intrusion, the attacker claimed to have manipulated the databases, and to allegedly have been able to gain control over the system and all of the documents contained on it, although KPN, claims the documents contained on the server were all publicly available. Moreover the attacker claimed the attack was successful since he could obtain the password (braTica4) used for administrative tasks on the server. As a precaution, while further information is collected about the incident, Gemnet CSP, KPN’s certificate authority division, has also suspended access to their website.
The breach is very different, in purpose and motivations, from the one occurred to Diginotar, at the end of July, which led to the issuance of more than 500 bogus Certificates (on behalf of Google, Microsoft, and other companies). In case of Diginotar the certificates were used to intercept about 300,000 Iranians, as part of what was called “Operation Black Tulip“, a campaign aimed to eavesdrop and hijack dissidents’ emails. For the chronicles, the same author of the Diginotar hack, the Infamous Comodo Hacker, had already compromised another Certification Authority earlier this year, Comodo (which was at the origin of his nickname). In both cases, the hacks were performed for political reasons, respectively as a retaliation for the Massacre of Srebrenica (in which the Comodo Hacker claimed the Dutch UN Blue Helmets did not do enough to prevent it), and as a retaliation for Stuxnet, allegedly developed in a joint effort by Israel and US to delay Iranian Nuclear Program.
But although resounding, these are not the only examples of attacks or security incidents targeting Certification Authorities: after all, the attacks against CAs started virtually in 2010 with the infamous 21th century weapon Stuxnet, that could count among its records, the fact to be the first malware using a driver signed with a valid certificate belonging to Realtek Semiconductor Corps. A technique also used by Duqu, the so called Duqu’s son.
Since then, I counted 11 other breaches, perpetrated for different purposes: eavesdropping (as is the case of the Infamous Comodo Hacker), malware driver signatures, or “simple” compromised servers (with DDoS tools as in case of KPN).
