Overview
Targeted attacks and malware campaigns
Monkey business
Recently we published our analysis of CozyDuke, yet another cyber-espionage APT from the ‘Duke’ family – which also includes MiniDuke, CosmicDuke and OnionDuke. CozyDuke (also known as ‘CozyBear’, ‘CozyCar’ and ‘Office Monkeys’) targets government organisations and businesses in the US, Germany, South Korea and Uzbekistan.
The attack implements a number of sophisticated techniques, including encryption, anti-detection capabilities and a well-developed set of components that are structurally similar to earlier threats within the ‘Duke’ family.
However, one of CozyDuke’s most notable features is its use of social engineering to get an initial foothold in targeted organisations. Some of the attackers’ spear-phishing emails contain a link to hacked web sites – including high-profile, legitimate sites – that host a ZIP archive. This archive contains a RAR SFX that installs the malware while showing an empty PDF as a decoy. Another approach is to send out fake flash videos as email attachments. A notable example (which also gives the malware one of its names) is ‘OfficeMonkeys LOL Video.zip’. When run, this drops a CozyDuke executable on to the computer, while playing a ‘fun’ decoy video showing monkeys working in an office. This encourages victims to pass the video around the office, increasing the number of compromised computers.

The successful use of social engineering to trick staff into doing something that jeopardises corporate security – by CozyDuke and many other targeted attackers – underlines the need to make staff education a core component of any business security strategy.
Naikon: gathering geo-political intelligence
In May we published our report on the Naikon APT. Naikon is used in campaigns against sensitive targets in South-eastern Asia and around the South China Sea. The attackers seem to be Chinese-speaking and have been active for at least five years, focusing their attention on top-level government agencies and civil and military organizations in countries such as the Philippines, Malaysia, Cambodia, Indonesia, Vietnam, Myanmar, Singapore, Nepal, Thailand, Laos and China.
As with so many campaigns of this kind, the attackers use spear-phishing emails to trick unsuspecting staff into loading the malware. Emails include an attached file containing information likely to be of interest to the victim. The file seems to be a standard Word document, but it is really an executable with a double extension, or an executable that uses the RTLO (right to left override) mechanism to mask the real extension of the file. If the victim clicks on the file, it installs spyware on the computer while displaying a decoy document to avoid arousing suspicion.

Naikon’s main module is a remote administration tool: this module supports 48 commands to exercise control over infected computers. These include commands to take a complete inventory, download and upload data, and install add-on modules. In addition, Naikon sometimes uses keyloggers to obtain employees’ credentials.
Each target country is assigned its own operator, who is able to take advantage of local cultural features – for example, the tendency to use personal email accounts for work. They also made use of a specific proxy server within a country’s borders, to manage connections to infected computers and transfer data to the attackers’ Command-and-Control (C2) servers.
You can find our main report and follow-up report on our web site.
Spying on the spies
While researching Naikon, we uncovered the activities of the Hellsing APT group. This group focused mainly on government and diplomatic organisations in Asia – most victims are located in Malaysia and the Philippines, although we have also seen victims in India, Indonesia and the US.
In itself, Hellsing is a small and technically unremarkable cyber-espionage group (around 20 organisations have been targeted by Hellsing). What makes it interesting is that the group found itself on the receiving end of a spear-phishing attack by the Naikon APT group – and decided to strike back! The target of the email questioned the authenticity of the email with the sender. They subsequently received a response from the attacker, but didn’t open the attachment. Instead, shortly afterwards they sent an email back to the attackers that contained their own malware. It’s clear that, having detected that they were being targeted, the Hellsing group was intent on identifying the attackers and gathering intelligence on their activities.

In the past, we’ve seen APT groups accidentally treading on each other’s toes – for example, stealing address books from victims and then mass-mailing everyone on each of the lists. But an ATP-on-APT attack is unusual.
Grabit and run
Many targeted attack campaigns focus on large enterprises, government agencies and other high-profile organisations. So it’s easy to read the headlines and imagine that such organisations are the only ones on the radar of the attackers. However, one of the campaigns we reported last quarter showed clearly that it’s not only ‘big fish’ that attackers are interested in. Every business is a potential target – for its own assets, or as a way of infiltrating another organisation.
The Grabit cyber-espionage campaign is designed to steal data from small- and medium-sized organisations – mainly based in Thailand, Vietnam and India, although we have also seen victims in the US, UAE, Turkey, Russia, China, Germany and elsewhere. The targeted sectors include chemicals, nanotechnology, education, agriculture, media and construction. We estimate that the group behind the attacks has been able to steal around 10,000 files.
The malware is delivered in the form of a Word document attached to an email. The document contains a malicious macro named ‘AutoOpen’. This macro opens a socket over TCP and sends an HTTP request to a remote server that was hacked by the group to serve as a malware hub. Then the program used to carry out the spying operation is downloaded from this server. In some cases, the macro is password protected (the attackers seem to have forgotten that a DOC file is actually an archive; and when it’s opened in an editor, macro strings are shown in clear-text). The attackers control compromised computers using a commercial spying tool called HawkEye (from HawkEyeProducts). In addition, they use a number of Remote Administration Tools (RATs).
The attackers have implemented some techniques designed to make Grabit hard to analyze,, including variable code sizes, code obfuscation and encryption. On the other hand, they fail to cover their tracks in the system. The result is a ‘weak knight in heavy armor’, suggesting that the attackers didn’t write all the code themselves.
The return of Duqu
In spring 2015, during a security sweep, Kaspersky Lab detected a cyber-intrusion affecting several internal systems. The full-scale investigation that followed uncovered the development of a new malware platform from one of the most skilled, mysterious and powerful groups in the APT world – Duqu, sometimes referred to as the step-brother of Stuxnet. We named this new platform ‘Duqu 2.0′.
The malware platform was designed to survive almost exclusively in the memory of infected systems. #KLReport
Tweet
In the case of Kaspersky Lab, the attack took advantage of a zero-day vulnerability in the Windows kernel (patched by Microsoft on 9 June 2015) and possibly up to two others (now patched) that were also zero-day vulnerabilities at the time. The main goal of the attackers was to spy on Kaspersky Lab technologies, ongoing research and internal processes.
However, Kaspersky Lab was not the only target. Some Duqu 2.0 infections were linked to the P5+1 events related to negotiations with Iran about a nuclear deal. The attackers appear to have launched attacks at the venues for some of these high-level talks. In addition, the group launched a similar attack related to the 70th anniversary event of the liberation of Auschwitz-Birkenau.
One of Duqu 2.0’s most notable features was its lack of persistence, leaving almost no traces in the system. The malware made no changes to the disk or system settings: the malware platform was designed in such a way that it survives almost exclusively in the memory of infected systems. This suggests that he attackers were confident that they could maintain their presence in the system even if an individual victim’s computer was re-booted and the malware was cleared from memory.
The Duqu 2.0 technical paper and analysis of the persistence module can be found on our web site.
Malware stories
Simda’s hide-and-seek malware business
In April, Kaspersky Lab was involved in the take-down of the Simda botnet, co-ordinated by the Interpol Global Complex for Innovation. The investigation was started by Microsoft and expanded to other participants, including Trend Micro, the Cyber Defense Institute, officers from the Dutch National High Tech Crime Unit (NHTCU), the FBI, the Police Grand-Ducale Section Nouvelles Technologies in Luxembourg, and the Russian Ministry of the Interior’s Cybercrime Department “K” supported by the INTERPOL National Central Bureau in Moscow.
As a result of the operation, 14 servers in the Netherlands, the US, Luxembourg, Poland and Russia were taken down. Preliminary analysis of some of the sink-holed server logs revealed 190 countries that had been affected by the botnet.
Preliminary analysis revealed 190 countries that had been affected by the Simda botnet. #KLReport

The bots are distributed via a series of infected web sites that re-direct visitors to exploit kits. The bots download and run additional components from their own update servers and are able to modify the hosts file on the infected computer: in this way, once-infected computers can keep sending out HTTP requests to the malicious servers, indicating that they are still vulnerable to re-infection using the same exploit kits.
Although the Simda botnet is relatively large, with an estimated 770,000 infected computers, the authors went to great lengths to try and make it ‘fly under the radar’ of anti-malware systems. The malware is able to detect emulation, security tools and virtual machines; it uses a number of methods to detect research sandbox environments with a view to tricking researchers by consuming all CPU resources or notifying the botnet owner about the external IP address of the research network; and it implements server-side polymorphism.
Simda also de-activates itself after a short time. This is closely related to the purpose of this particular botnet: it’s a delivery mechanism, designed to disseminate potentially unwanted and malicious software. The distributors wanted to guarantee that only their client’s malware would be installed on infected computers.
Kaspersky Lab products currently detect hundreds of thousands of modifications of Simda, together with many different third-party malicious programs distributed using the Simda botnet. You can use our free Simda bot IP scanner to check if your IP has connected to a Simda C2 server in the past.
Phishing, but not as we know it
Early in 2014 a serious vulnerability in the OAuth and OpenID protocols was discovered by Wang Jing, a PHD student at the Nanyang Technological University in Singapore. He found what he named the ‘covert redirect’ vulnerability, which could allow an attacker to steal data following authentication (a summary of the problem, including a link to Jing’s blog, can be found on Threatpost).
Recently, we discovered a phishing campaign that takes advantage of the OAuth vulnerability. OAuth lets customers of online services give third parties limited access to their protected resources without sharing their credentials. It is commonly used by applications for social networks – for example, to obtain access to someone’s contact lists or other data.
The Kaspersky Lab customer who reported the attack received an email saying that someone had used their Windows Live ID and asking them to follow a link to the Windows Live site and follow the security requirements outlined there.
Do not allow untrusted applications to access your data #KLReport

On the face of it, it seems like a standard phishing technique – one that would result in the victim being re-directed to a fake site. But in this case, the link led to the legitimate site. The victim’s login credentials aren’t stolen and they are logged in to the legitimate site. However, after authorization, the victim receives a request for a range of permissions from an unknown application. This can include automatic login, access to profile information, contact list and email addresses. If the victims hands over these rights, it offers the cybercriminals access to their personal information – information that they can use to distribute spam, phishing links or for other fraudulent purposes.
We would recommend the following to safeguard your personal data.
Do not click on links you receive by email or in messages on social networks.
Do not allow untrusted applications to access your data.
Before you agree to such requests, carefully read the description of the access rights being requested by an application
Read reviews and feedback on the application on the Internet.
Review the rights of currently installed applications and modify the settings if you need to.
Smart cities but not-so-smart security
The use of CCTV systems by governments and law enforcement agencies for surveilling public places has grown enormously in recent years. Most of us accept them as a reasonable trade-off between privacy and security. However, this rather assumes that the data gathered using this technology will be handled securely and responsibly, to ensure that the benefits aren’t outweighed by any potential dangers.
Many CCTV cameras have a wireless connection to the Internet, enabling police to monitor them remotely. However, this is not necessarily secure: it’s possible for cybercriminals to passively monitor security camera feeds, to inject code into the network – thereby replacing a camera feed with fake footage – or to take systems offline. Two security researchers (Vasilios Hioureas from Kaspersky Lab and Thomas Kinsey from Exigent Systems) recently conducted research into the potential security weaknesses in CCTV systems in one city. You can read Vasilios’s report on our web site).
Aspects of life are being made digital & security should be considered as part of the design stage #KLReport
Tweet
The researchers started by looking at the surveillance equipment in locations across the city. Unfortunately, there had been no attempt to mask the branding of the cameras, so it was easy to determine the makes and models of the cameras, examine the relevant specs and create their own scale model in the lab. The equipment being used provided effective security controls, but these controls were not being implemented. Data packets passing across the mesh network were not being encrypted, so that an attacker would be able to create their own version of the software and manipulate data travelling across it.
It’s important to note that they did not attempt to hack into the real network, but analyzed the hardware and communication protocols and built a scale model. The network topology of the surveillance camera network is unlike a standard home wireless network. On a home network, all devices connect to the Internet and one another through a router. Any device connected to that router could potentially trick the other devices into thinking it’s the router and monitor or change data by performing a Man-in-the-Middle attack.
The surveillance camera network is more complicated, because of the distances the data needs to travel. The data must travel from any given camera through a series of nodes eventually leading back to a hub (in a real world implementation, this might be a police station). The traffic follows the path of least resistance where each node has the ability to communicate with several others and selects the easiest path back to the hub.
Hioureas and Kinsey built a series of fake nodes that purported to offer a direct line of communication to a simulated police station. Since they knew all the protocols used on the network, they were able to create a Man-in-the-Middle node that seemed to offer the path of least resistance, causing the real nodes to relay their traffic through their malicious node.
One potential use for attackers would be to spoof footage sent to a police station. This could make it appear as if there was an incident in one location, thereby distracting police from a real attack occurring elsewhere in the city.
The researchers reported these issues to the authorities responsible for the city surveillance systems concerned and they are in the process of fixing the security problems. In general, it’s important that WPA encryption, protected by a strong password, is implemented in these networks; that labelling is removed from hardware, to make it harder for would-be attackers to find out how the equipment operates; and that footage is encrypted as it travels through the network.
The wider issue here is that more and more aspects of everyday life are being made digital: if security isn’t considered as part of the design stage, the potential dangers could be far-reaching – and retro-fitting security might not be straightforward. The Securing Smart Cities initiative, supported by Kaspersky Lab, is designed to help those responsible for developing smart cities to do so with cyber-security in mind.
Statistics
All the statistics used in this report were obtained using the Kaspersky Security Network (KSN), a distributed antivirus network that works with various anti-malware protection components. The data was collected from KSN users who agreed to provide it. Millions of Kaspersky Lab product users from 213 countries and territories worldwide participate in this global exchange of information about malicious activity.
Mobile threats
Mobile banker Trojans still remain among the top mobile threats. In our Q1 2015 report, we mentioned Trojan-SMS.AndroidOS.OpFake.cc, which could attack at least 29 banking and financial applications. The latest version of this Trojan can now attack 114 banking and financial applications. Its main goal is to steal the user’s online credentials. Serving the same purpose, it also attacks several popular email applications.
Trojan-Spy.AndroidOS.SmsThief.fc also deserves a mention. Cybercriminals managed to add their code into the original banking application without affecting its operation, making this Trojan more difficult to detect.

A new iOS Trojan, Trojan.IphoneOS.FakeTimer.a, emerged in Q2. It is interesting in that it is an iOS version of a malicious Android app which emerged several years ago. FakeTimer.a attacks even non-jailbroken devices. Its payload is rather primitive: it is a regular phishing application created to steal money from Japanese users.
In Q2, Trojans which can use root privileges to display advertisements to users or install advertising applications became especially visible. A total of six such malicious programs landed in the Q2 TOP 20 of malicious malware.
The number of new mobile threats
In Q2 2015, Kaspersky Lab mobile security products detected 291,887 new malicious mobile programs, a 2.8-fold increase on Q1 2015.

Distribution of new mobile malware by type, Q2 2015
The ranking of malware objects for mobile devices for the second quarter of 2015 was headed by RiskTool (44.6%). These are legitimate applications that are potentially dangerous for users – if used carelessly or manipulated by a cybercriminal, they could lead to financial losses.
Potentially unwanted advertising apps came second with 19%.
SMS Trojans have previously led this ranking, but in Q2 they were only in the fourth place with 8.1% – this is 12.9% lower than in Q1. The lower share taken by these malicious programs is in part accounted for by the fact that those who were previously active distributing SMS Trojans have started using ‘cleaner’ monetization techniques (as testified by the increased RiskTool shares), or prefer to use other types of malware. Thus the Trojan share increased from 9.8% in Q1 to 12.4% in Q2.

The top position in the rankings was occupied by DangerousObject.Multi.Generic (17.5%). This is how new malicious applications are detected by the KSN cloud technologies, which help our products to significantly shorten the response time to new and unknown threats.
Trojan-SMS.AndroidOS.Podec.a (9.7%) has been among the Top Three malicious mobile programs for three quarters in a row due to its active dissemination.
Trojan-SMS.AndroidOS.Opfake.a (8.0%) has been quickly rising to the top lines of the ranking. While in Q3 2014 it was in the 11th place only,it is now in the TOP 3 of mobile malware. Obfake.bo, another representative of this malware family, is in 15th place.
It is also worth mentioning the appearance of Backdoor.AndroidOS.Obad in the TOP 20 ranking – in fact, it jumped to fourth place all at once. This is a multi-functional Trojan, capable of sending SMS to premium-rate numbers; downloading other malware programs, installing them on the infected device and/or sending them further via Bluetooth; and remotely performing commands in the console. We wrote about it two years ago, and its capabilities have remained virtually unchanged ever since.
Another interesting thing is that although this ranking does not include adware programs, six of the TOP 20 malicious mobile programs use advertisements as the main vehicle of monetization. Unlike regular advertisement modules, Trojan.AndroidOS.Rootnik.a, three programs of the Trojan.AndroidOS.Ztorg family, Trojan-Downloader.AndroidOS.Leech.a and Trojan.AndroidOS.Fadeb.a do not carry any productive payload with them. Their goal is to deliver to the user as much advertising as possible in various ways, including installation of new adware programs. These Trojans can use root privileges to conceal themselves in the system folder – this makes it very difficult to delete them.
Mobile banker Trojans
In Q2 2015, we detected 630 mobile banker Trojans. It should be noted that the number of new malware programs belonging to this category is now growing at a much slower rate.

Vulnerable applications used by fraudsters
The ranking of vulnerable applications below is based on information about the exploits blocked by our products. These exploits were used by cybercriminals in Internet attacks and in attempts to compromise local applications, including those installed on mobile devices.
Distribution of exploits used in attacks by type of application attacked, Q2 2015
The rating of exploits has seen little change from the first quarter. The Browsers category (60%) maintained its top position in the Q2 2015. Currently most exploit packs contain a pack of exploits for Adobe Flash Player and Internet Explorer. It is worth mentioning the growing number of exploits for Adobe Flash Player (up by six percentage points) which is caused by the large number of spam mass mailings containing malicious PDF documents.
The number of exploits for Java continues to decrease (down four percentage points): in Q2 we did not see any new exploits for Java.
In the second quarter of 2015 we registered the use of four new vulnerabilities in Adobe Flash Player:
CVE-2015-3113
CVE-2015-3104
CVE-2015-3105
CVE-2015-3090
Although the share of exploits for Adobe Flash Player in our rating is only 3%, there are many more of them in the “wild”. When considering these statistics, we should take into account that Kaspersky Lab technologies detect exploits at various stages. The Browsers category also includes detection of landing pages that “distribute” exploits. According to our observations, they are most often exploits for Adobe Flash Player
Online threats (Web-based attacks)
The statistics in this section were derived from web antivirus components that protect users from attempts to download malicious objects from a malicious/infected website. Malicious websites are created deliberately by malicious users; infected sites include those with user-contributed content (such as forums), as well as compromised legitimate resources.
Online threats in the banking sector
In the second quarter of 2015, Kaspersky Lab solutions blocked attempts to launch malware capable of stealing money via online banking on the computers of 755,642 users. This figure represents an 18.7% decrease compared to the previous quarter (735,428).

In our previous reports, the Top 10 was made using the number of users attacked. Although this aspect is very important, it depends on the number Kaspersky Lab product users in the countries.
To evaluate and compare the degree of risk of being infected by banking Trojans which user computers are exposed to worldwide, we calculate the percentage of Kaspersky Lab product users who encountered this threat during the reporting period in the country, of all users of our products in this county.
