Bitcoin: A brief history
FortiGuard Labs continues to investigate a series of attacks on Bitcoin users. In our first blog , we provided a deep analysis of malicious samples from the Bitcoin Orcus RAT campaign. In this second part, we recreate the full path of a multistage complex attack, shed some light on some other activities of these criminal actors, and reveal their possible identities.
In there was a simple and straightforward attack on its users. Somebody registered a domain with very similar name - B l tcointalk. After that, criminals distributed this fake link on Reddit. We found traces of this attack in the Archive. Fifty BTC is worth a small fortune in December of Back in May , however, 50 BTC cost way less.
Obviously, the expectations of these attackers were quite high. However, this attempt ended in failure — we could not find any transactions for that specified bitcoin wallet. Some users of the original Bitcointalk. They did not notice the forgery right away, but were very suspicious since the author of these messages was a newbie who had zero posts on the forum. In the ensuing discussion, one of the users offered to restrict newbie users from sending PMs.
In early , the domain B l tcointalk. On October 18, , however, this domain name received a new owner: somebody with the email cobainin[ ]yandex. Two days before that, somebody with the nickname harrison started a new thread on the original Bitcointalk. This newbie user wanted to buy an old bitcointalk. Our suspicion was that these accounts would be used for further attacks on the users of bitcointalk.
As we closely looked into other domains that are related to cobainin[ ]yandex. The content of these videos was taken from other sources, but the descriptions of these videos was altered.
They now contains links to several fake sites: q unthy. It turns out that all these fake sites are controlled by the same attackers.
We decided to start our investigation from q unthy. Q unthy. After that, several redirects occur:. At the end of this redirection chain an archive is downloaded which contains a custom-packed Orcus RAT, which was already described in our previous article. Normally, if a user hovers his mouse over a link, the legit URL is shown in the browser:.
Figure 4. Fake links on q unthy. However, this site uses a trick here to capture users, because once a click is made the user is redirected to a completely different URL. This trick is done with use of the handler for onClick events.
This handler simply rewrites the hyperlink after a mouse click:. Figure 5. Part of the source code for q unthy. As a result, unsuspecting users are redirected to another domain controlled by the criminals — the infamous bltcolntalk. This page is actually a copy of a legitimate bitcointalk. The bogus panel shown in the orange rectangle on the picture below leads to the phishing login page on the same domain.
Figure 6. Pop-up banner and bogus panel of the b l tcolntalk. However, phishing is not the only attack vector here. After about 30 seconds another small banner pops up shown in the red rectangle, above. This banner uses the same trick with onClick handler to hide its real destination. The choices shown on the banner are fictional. Regardless of which one they choose, users will simply be redirected to a malicious link hosted on the file sharing site desfichiers.
As a result, another malicious file is downloaded described below :. It also leads to a fake domain registered under the same email address we will come back to this link later :. Here we will simply list its main features:. After publication of our previous article , FortiGuard Labs was contacted by a person who claims that he is the owner of Orcus Technologies.
He wrote that he was rather disturbed by the fact that his software was being misused. He also claims that he managed to take down the server We can confirm that a new sample tried to use the IP The domain adobe.
The interface tries to mimic the original Adobe Flash Player download page, and it does so quite well, except for the fact that Flash Player version it advertises was already outdated at the time of writing. However, once again the same trick with onClick handler is used. This time, in addition to the original download page, a window with a malicious link is opened. This malicious link is the beginning of a long chain of redirects shown below.
Why the criminals decided to use such a long chain comprised of controlled and third-party resources is not quite clear. It is obvious that the length of the chain makes it vulnerable. Another drawback of such a scheme is the time required for this chain to complete because it forces the intended victim to wait longer before the final payload can be downloaded.
The payload here is the file sourcecode. This is exactly the same VBS downloader that was sent as an attachment in previous phishing emails.
FortiGuard Labs described this downloader in our previous related article. We noted that all connected malicious domains were registered under different names, but they are all registered under the same email - cobainin[ ]yandex. As a result, we decided to explore other domains registered using this email address. The list is shown below. Most of these domains have already been described before. The last three shown above are trying to mimic the bitcoin trading platform wex.
There is another interesting related domain: nootropicplace. Since it has been protected by Privacy Protect, but before that date it was registered under the same email address as all the others. While cannot comment on whether selling these drugs is legal or not, what is alarming is the fact that these drugs are sold for bitcoins, and that there is no ability to look into the addresses of the sellers to determine if they are legitimate. We also conducted an investigation in an attempt to find out more about these possible criminals.
We checked the registrant names and addresses that were used for registration of the malicious domains, but we believe that this data is fictitious. Nevertheless, in addition to the fake email addresses used, the attackers left many other pieces of information that we could track. For example, the source code of the fake bltcolntalk. More info was found in the Google cache. At some point there had been an advertisement attempting to sell this domain:.
We could not find any malicious activity related to the use of this domain yet, and its current purpose is unclear. However, we found some interesting conversations on Reddit about it:.
Somebody using the nickname r3xxb0bb claims that he managed to buy domain rightinquirer. The post was written on the September 14, — the day after rightinquirer. As a result, we have now established a strong connection between r3xxb0bb and cobainin[ ]yandex. This username is not popular.
Therefore, we decided to search for other uses of the same username. In addition, the same username is used by this YouTube account:.
So we checked the registration records for the domain sparky While most of fields were obfuscated with the service gandi. We were also able to find the Facebook group of Sparky Figure The Bobb Shires profile and Sparky team photos photos intentionally blurred. While the username itself is quite unique, we still wanted to find more connections. As a result, we read all the posts of Reddit user r3xxb0bb and found this Reddit thread. In this thread r3xxb0bb and another user discuss the isolation of a robot controller.
This is the same competition in which Sparky took part. FortiGuard found several malicious domains that were used for phishing and the spreading of the custom-packed Orcus RAT.
We traced this malicious activity to the Reddit account r3xxb0bb. However, we cannot confirm whether this account is still used by him.
Because the criminals related to cobainin[ ]yandex. Failed attempt Bitcointalk.
