However, all these vulnerabilities were at system level, giving a remote malicious user the opportunity to penetrate the victim machine from outside via a port. The number of vulnerabilities detected in this program is already in the dozens, and the most critical of them provide a remote malicious user with the ability to install any file on a victim machine which has been used to view a compromised site.
Thankfully, up until now we have been able to avoid the situation where there has been exploit code publicly available for a vulnerability for which no patch yet exists. However, in the case of viruses written for zero day vulnerabilities, there are no patches. Microsoft has managed to keep this situation under control by working closely with companies which specialize in identifying vulnerabilities.

In spite of the fact that in some cases, it has taken several months from the moment the vulnerability was identified to a patch being released, information about the vulnerability was not publicized, and was therefore not widely available. However, at the end of a watershed was reached. There were two critical vulnerabilities in Windows, a month apart, which were publicized before a patch was made available.
In both cases the vulnerabilities were used by malicious programs to spread. The vulnerability was first made public in May , but at that stage, Microsoft was unable to find any way in which the vulnerability could be exploited to execute random code on a victim machine, and did not rate it critical. As a result, fixing this vulnerability was not viewed as a priority.
However, it seems that the researchers from Computer Terrorism understood the vulnerability better than Microsoft. The proof of concept code, after a little tweaking, made it possible to install and execute a file on a victim system without the knowledge or consent of the user. It took virus writers a little over a week before they began to place malicious code to exploit the vulnerability on compromised sites.
We detected a number of Trojans which propagated in this way. The only method to combat the exploit was to disable Java Script in Internet Explorer, but only a small number of users did this.
Tens, or possibly hundred of millions of users around the globe were left unprotected against these Trojans; this was the first case in which a Trojan exploited a vulnerability in Windows for which no patch existed. It might have been expected that Microsoft would do everything possible to correct this error. After all, the company has been positioning itself recently being in the forefront of the battle against malicious code; it has released its own antivirus solution and is taking legal action against virus writers.
The company announced that in spite of the fact that the vulnerability was rated critical, no unscheduled patch would be released. Since Microsoft has been releasing patches every second Tuesday of the month. Facts are facts — three weeks had passed since the proof of concept code had appeared, and six months had passed since the vulnerability was first detected. Overall, this was a significant period of time, during which any IE user could have been infected.
This was a cause for considerable concern, but could have been seen as a one-off. However, within two weeks the scenario was repeated, and the potential consequences were far more serious. On 26th December some antivirus companies received mysterious WMF-files. Analysis showed that these files contained executable code which would download files from sites which were known to be spreading adware and spyware.
The malicious code would be executed when a user opened the WMF file. Other actions, such as using explorer to open the directory in which the file was located, viewing the file properties etc. It was clear that this was the latest zero day vulnerability, and Microsoft knew nothing about it. The most worrying thing is that the virus writing community not only detected this vulnerability before Microsoft did, but also before any other major company specializing in the identification of vulnerabilities.
Many security professionals spent the next two days analyzing the vulnerability. Information on the vulnerability was published, and the majority of antivirus companies developed heuristic detection for the malicious WMF files. As the vulnerability was present in all versions of Windows, the situation threatened to spiral out of control.
Worms and mass mailings which used the malicious code to exploit the vulnerability were also detected. Thankfully, all of this took place over Christmas. Fewer people were using the Internet, and many major companies were also on holiday. The number of Internet users was far less than normal, and this prevented a major disaster. So what was Microsoft doing about the problem? Security Bulletin KB was published, which stated that the vulnerability had been identified and listed the vulnerable versions of Windows. More concrete information was issued on 3rd January, when Microsoft stated that a patch would be issued in the monthly patch bulletin on 10th January.
The justification for this action was that the patch needed thorough testing and localization for all versions of Windows. Microsoft also asserted that although the problem was critical, no significant virus epidemic had been detected. The IT world was horrified. The number of articles criticizing Windows heavily was equal to the number of malicious wmf files detected. At the same time, the beta patch developed by Microsoft for Windows XP was leaked. The patch was published on a number of sites, and this patch, together with a unofficial third party patch developed by Ilfak Gulfanov, was the only immediately available solution.
The situation is clear. One very important aspect of this case is that the vulnerability was first identified by members of the computer underground. Kaspersky Lab has researched the case, and the picture seems to be the following:. It seems most likely that the vulnerability was detected by an unnamed person around 1st December , give or take a few days.
It took a few days for the exploit enabling random code to be executed on the victim machine to be developed. Around the middle of December, this exploit could be bought from a number of specialized sites. The data we have, plus the Russian involvement, make it clear that information about the vulnerability was not passed to companies such as eEye or iDefence, which specialize in identifying vulnerabilities.
Thirdly, research bodies did not have information about the fact that the exploit was being sold, due to the fact that it was created for the Russian market. Mobile malware appeared to reach a stable phase in its evolution in the fourth quarter of The number of new Trojan programs grew steadily, in line with our predictions.
Many of the forecasts contained in our last quarterly report, published in September were confirmed.
The Trojan accesses the address book of the infected device and sends it via Bluetooth to the nearest accessible device. Such Trojans are designed not only to infect handsets, but also any PC which a telephone is connected to. The Cardblock family of Trojans installs a password to access the device card. If the malicious code is deleted, the user will no longer be able to access data on the card. Both Gpcode and Krotten written for PCs did this, and Trojans for mobiles are unlikely to be far behind. Towards the end of , the hypothetical epidemic of mobile malware became a reality.
