Beginning in the second quarter of 2017, Kaspersky’s Global Research and Analysis Team (GReAT) began publishing summaries of the quarter’s private threat intelligence reports in an effort to make the public aware of what research we have been conducting. This report serves as the next installment, focusing on important reports produced during Q3 of 2017.
As stated last quarter, these reports will serve as a representative snapshot of what has been offered in greater detail in our private reports in order to highlight significant events and findings we feel most should be aware of. For brevity’s sake, we are choosing not to publish indicators associated with the reports highlighted. However, if you would like to learn more about our intelligence reports or request more information for a specific report, readers are encouraged to contact: email@example.com.
The third quarter demonstrated to us that Chinese-speaking actors have not “disappeared” and are still very much active, conducting espionage against a wide range of countries and industry verticals. In total, 10 of the 24 reports produced centered around activity attributed to multiple actors in this region.
The most interesting of these reports focused on two specific supply chain attacks; Netsarang / ShadowPad and CCleaner. In July 2017, we discovered a previously unknown malware framework (ShadowPad) embedded inside the installation packages hosted on the Netsarang distribution site. Netsarang is a popular server management software used throughout the world. The ShadowPad framework contained a remotely activated backdoor which could be triggered by the threat actor through a specific value in a DNS TXT record. Others in the research community have loosely attributed this attack to the threat actor Microsoft refers to as BARIUM. Following up on this supply chain attack, another was reported initially by Cisco Talos in September involving CCleaner, a popular cleaner / optimization tool for PCs. The actors responsible signed the malicious installation packages with a legitimate Piriform code signing certificate and pushed the malware between August and September.
Q3 also showed China is very interested in policies and negotiations involving Russia with other countries. We reported on two separate campaigns demonstrating this interest. To date, we have observed three separate incidents where Russia and another country hold talks and are targeted shortly thereafter, IndigoZebra being the first. IronHusky was a campaign we first discovered in July targeting Russian and Mongolian government, aviation companies, and research institutes. Earlier in April, both conducted talks related to modernizing the Mongolian air defenses with Russia’s help. Shortly after these talks, the two countries were targeted with a Poison Ivy variant from a Chinese-speaking threat actor. In June, India and Russia signed a much awaited agreement to expand a nuclear power plant in India, as well as further define the defense cooperation between the two countries. Very soon after, both countries energy sector were targeted with a new piece of malware we refer to as “H2ODecomposition”. In some case this malware was masquerading as a popular Indian antivirus solution (QuickHeal). The name of the malware was derived from an initial RC5 string used in the encryption process (2H2O=2H2+O2) which describes a chemical reaction used in hydrogen fuel cells.
Other reports published in the third quarter under chinese-speaking actors were mainly updates to TTPs by known adversaries such as Spring Dragon, Ocean Lotus, Blue Termite, and Bald Knight. The Spring Dragon report summarized the evolution of their malware to date. Ocean Lotus was observed conducting watering hole attacks on the ASEAN website (as done previously) but with a new toolkit. A new testing version of Emdivi was discovered in use by Blue Termite as well as their testing of CVE-2017-0199 for use. Finally, Bald Knight (AKA – Tick) was seen using their popular XXMM malware family to target Japan and South Korea.

The third quarter was a bit slower with respect to Russian speaking threat actors. We produced four total reports, two of which focused on ATM malware, one on financial targeting in Ukraine and Russia, and finally a sort of wrap-up of Sofacy activity over the summer.
The ATM related reports centered around Russian speaking actors using two previously unknown pieces of malware designed specifically for certain models. “Cutlet Maker” and “ATMProxy” both ultimately allowed the users to dispense cash at will from a chosen cartridge within the ATMs. ATMProxy was interesting since it would sit dormant on an ATM until a card with a specific hard coded number was inserted, at which point it would dispense more cash than what was requested.
Another report discussed a new technique utilizing highly targeted watering holes to target financial entities in Ukraine and Russia with Buhtrap. Buhtrap has been around since at least 2014, but this new wave of attacks was leveraging search engine optimization (SEO) to float malicious watering hole sites to the top of search results, thus providing more of a chance for valid targets to visit the malicious sites.
Finally, we produced a summary report on Sofacy’s summertime activity. Nothing here was groundbreaking, but rather showed the group remained active with their payloads of choice; SPLM, GAMEFISH, and XTUNNEL. Targeting also remained the same, focusing on European defense entities, Turkey, and former republics.
Below is a list of report titles for reference:
ATMProxy – A new way to rob ATMs
Cutlet maker – Newly identified ATM malware families sold on Darknet
Summertime Sofacy – July 2017
Buhtrap – New wave of attacks on financial targets
The last quarter also had us reporting on yet another member of the Lamberts family. Red Lambert was discovered during our previous analysis of Grey Lambert and utilized hard coded SSL certificates in its command and control communications. What was most interesting about the Red Lambert is that we discovered a possible operational security (OPSEC) failure on the actor’s part, leading us to a specific company who may have been responsible, in whole or in part, for the development of this Lambert malware.

We were also able to produce two reports on Korean speaking actors, specifically involving Scarcruft and Bluenoroff. Scarcruft was seen targeting high profile, political entities in South Korea using both destructive malware as well as malware designed more for espionage. Bluenoroff, the financially motivated arm of Lazarus, targeted a Costa Rican casino using Manuscrypt. Interestingly enough, this casino was compromised by Bluenoroff six months prior as well, indicating they potentially lost access and were attempting to get back in.
Report titles focusing on Korean-speaking actors:

Bluenoroff hit Casino with Manuscrypt
Finally, we also wrote seven other reports on “uncategorized” actors in the third quarter. Without going into detail on each of these reports, we will focus on two. The first being a report on the Shadowbrokers’ June 2017 malware dump. An anonymous “customer” who paid to get access to the dump of files posted the hashes of the files for the month, mainly due to their displeasure in what was provided for the money. We were only able to verify one of nine file hashes, which ended up being an already known version of Triple Fantasy.
The other report we’d like to highlight (“Pisco Gone Sour”) is one involving an unknown actor targeting Chilean critical institutions with Veil , Meterpreter, and Powershell Empire. We are constantly searching for new adversaries in our daily routine and this appears to be just that. The use of publicly available tools makes it difficult to attribute this activity to a specific group, but our current assessment based on targeting is that the actor may be based somewhere in South America.
Dark Cyrene – politically motivated campaign in the Middle East
Pisco Gone Sour – Cyber Espionage Campaign Targeting Chile
Crystal Finance Millennium website used to launch a new wave of attacks in Ukraine
New Machete activity – August 2017
Shadowbroker June 2017 Pack
The Silence – new trojan attacking financial organizations
Normally we would end this report with some predictions for the next quarter, but as it will be the end of the year soon, we will be doing a separate predictions report for 2018. Instead, we would like to point out one alarming trend we’ve observed over the last two quarters which is an increase in supply chain attacks. Since Q2, there have been at least five incidents where actors have targeted the supply chain to accomplish their goals instead of going directly after the end target; MeDoc, Netsarang, CCleaner, Crystal Finance, and Elmedia. While these incidents were not the result of just one group, it does show how the attention of many of the actors out there may be shifting in a direction that could be much more dangerous. Successfully compromising the supply chain provides easy access to a much wider target base than available through traditional means such as spear phishing. As an added benefit, these attacks can remain undetected for months, if not longer. It remains to be seen if this trend will continue into 2018, but given the successes from the five mentioned above, we feel we haven’t seen the last of this type of attack in the near future.
