Kaspersky Lab’s advanced exploit prevention system has identified a new Adobe Flash Zero Day exploit, used in an attack by a threat actor known as BlackOasis.
The exploit is delivered through a Microsoft Word document and deploys the FinSpy commercial malware. Kaspersky Lab has reported the vulnerability to Adobe, which has issued an advisory.
According to Kaspersky Lab researchers, the Zero Day, CVE-2017-11292, has been spotted in a live attack, and they advise businesses and government organisations to install the update from Adobe immediately.
The researchers believe that the group behind the attack was also responsible for CVE-2017-8759, another Zero Day, reported in September – and they are confident that the threat actor involved is BlackOasis, which Kaspersky Lab’s Global Research and Analysis Team began tracking in 2016.
Analysis reveals that, upon successful exploitation of the vulnerability, the FinSpy malware (also known as FinFisher) is installed on the target computer. FinSpy is a commercial malware, typically sold to nation states and law enforcement agencies to conduct surveillance. In the past, use of the malware was mostly domestic, with law enforcement agencies deploying it for surveillance on local targets. BlackOasis is a significant exception to this – using it against wide range of targets across the world. This appears to suggest that FinSpy is now fuelling global intelligence operations, with one country using it against another. Companies developing surveillance software such as FinSpy make this arms race possible.
The malware used in the attack is the most recent version of FinSpy, equipped with multiple anti-analysis techniques to make forensic analysis more difficult.
After installation, the malware establishes a foothold on the attacked computer and connects to its command and control servers located in Switzerland, Bulgaria and the Netherlands, to await further instructions and exfiltrate data.
Based on Kaspersky Lab’s assessment, the interests of BlackOasis span a whole gamut of figures involved in Middle Eastern politics, including prominent figures in the United Nations, opposition bloggers and activists, as well as regional news correspondents. They also appear to have an interest in verticals of particular relevance to the region. During 2016, the company’s researchers observed a heavy interest in Angola, exemplified by lure documents indicating targets with suspected ties to oil, money laundering and other activities. There is also an interest in international activists and think tanks.
So far, victims of BlackOasis have been observed in the following countries: Iraq, Afghanistan, Nigeria, Libya, Jordan, Tunisia, Saudi Arabia, Iran, the Netherlands, Bahrain, United Kingdom, Angola and Russia.
“The attack using the recently discovered zero-day exploit is the third time this year we have seen FinSpy distribution through exploits to zero-day vulnerabilities. Previously, actors deploying this malware abused critical issues in Microsoft Word and Adobe products. We believe the number of attacks relying on FinSpy software, supported by Zero Day exploits such as the one described here, will continue to grow,” said Anton Ivanov, the Lead Malware Analyst at Kaspersky Lab.
Kaspersky Lab security solutions successfully detect and block exploits utilising the newly discovered vulnerability.
Kaspersky Lab experts advise organisations to take the following action to protect their systems and data against this threat:
- If not already implemented, use the killbit feature for Flash software and, wherever possible, disable it completely.
- Implement an advanced, multi-layered security solution that covers all networks, systems and endpoints.
- Educate and train personnel on social engineering tactics as this method is often used to make a victim open a malicious document or click on an infected link.
- Conduct regular security assessments of the organisation’s IT infrastructure.
- Use Kaspersky Lab’s Threat Intelligence that tracks cyberattacks, incident or threats and provides customers with up-to-date relevant information that they are unaware of. Find out more at email@example.com.
Personal computing devices sales still decline in MEA
The Middle East and Africa (MEA) personal computing devices (PCD) market, which is made up of desktops, notebooks, workstations, and tablets, suffered a decline of -7.3% year on year in Q2 2017, according to the latest insights from International Data Corporation (IDC).
The global technology research and consulting firm’s Quarterly PCD Tracker for Q2 2017 shows that PCD shipments fell to around 6 million units for the quarter.
“As forecast, the market followed a similar pattern to recent quarters, with the downturn primarily stemming from a decline in shipments of slate tablets and desktops,” says Fouad Charakla, IDC’s senior research manager for client devices in the Middle East, Turkey, and Africa. “This was the result of desktop users increasingly switching to mobile devices such as notebooks or even refurbished notebooks, while users of slate tablets shifted to smartphones. These trends translated into year-on-year declines of -21.9% for desktops and -15.7% for slate tablets in Q2 2017, while shipments of notebooks and detachable tablets increased 11.0% and 63.3%, respectively over the same period.”
“Market sentiment in the region remained low overall, although an aggressive push from some slate tablet vendors meant the market declined much slower than expected,” continues Charakla. “At the same time, heightened competition has also made it harder for certain players to sustain their slate tablet businesses and generate profits, causing them to lose interest in the slate tablet market altogether. Despite this, slate tablets are still the most popular computing device among home users in the region.”
Looking at the region’s key markets, IDC’s research shows that when compared to Q2 2016 overall PCD shipments were down -11.4% in the UAE, -8.9% in Turkey, and -6.7% in the ‘Rest of Middle East’ sub-region (comprising Iran, Iraq, Syria, Yemen, Palestine, and Afghanistan). South Africa and Saudi Arabia bucked this trend, recording year-on-year increases of 3.5% and 9.6%, respectively.
A massive education delivery in Pakistan acted as a key driver for notebook shipments in the region overall. Similarly, the education sector was the biggest driver of detachable tablet shipments, triggered by a huge delivery in Kenya, as well as two other deliveries in Pakistan and Turkey, which enabled this category to achieve the fastest growth of all the PCD categories.
“While a component shortage prevented market players from reducing their prices too much, the average price of consumer notebooks experienced a considerable year-on-year decline in Q2 2017,” says Charakla. “This played a key role in driving demand from the consumer segment, and was reflected in the growing popularity of lower-priced notebook models.”
Looking at the PC market’s vendor rankings, each of the top five vendors maintained their respective positions compared to the previous quarter, with the top four all gaining share.

Although Samsung continued to lead the tablet market, the vendor rankings in the space saw quite a few changes, with Huawei catapulting itself to second place. Lenovo also climbed up a position compared to the previous quarter, causing Apple to drop to fourth place.

“Looking to the future, the MEA PCD market is expected to decline at a faster rate than previously forecast for 2017 as a whole,” says Charakla. “Technological shifts are playing a pivotal role in deciding the future of this market, with demand for certain products shifting to other PCD products and beyond (i.e., smartphones). Accordingly, shipments of slate tablets are expected to continue declining over the coming years as demand is cannibalized by smartphones. Meanwhile, the ongoing shift to mobile computing will see growth in the desktop market remain close to flat throughout IDC’s forecast period ending 2021. Notebook shipments will experience very slow growth beyond 2018, while detachable tablets will remain the fastest growing PCD category, eating away share from other computing devices.”
Gazer cyber-spies exposed
ESET has released new research into the activities of the Turla cyberespionage group, and specifically a previously undocumented backdoor that has been used to spy on consulates and embassies worldwide.
ESET’s research team are the first in the world to document the advanced backdoor malware, which they have named “Gazer”, despite evidence that it has been actively deployed in targeted attacks against governments and diplomats since at least 2016.
Gazer’s success can be explained by the advanced methods it uses to spy on its intended targets, and its ability to remain persistent on infected devices, embedding itself out of sight on victim’s computers in an attempt to steal information for a long period of time.
ESET researchers have discovered that Gazer has managed to infect a number of computers around the world, with the most victims being located in Europe. Curiously, ESET’s examination of a variety of different espionage campaigns which used Gazer has identified that the main target appears to have been Southeastern Europe as well as countries in the former Soviet Union Republic.
The attacks show all the hallmarks of past campaigns launched by the Turla hacking group, namely:
- Targeted organisations are embassies and ministries;
- Spearphishing delivers a first-stage backdoor such as Skipper;
- A second stealthier backdoor (Gazer in this instance, but past examples have included Carbon and Kazuar) is put in place;
- The second-stage backdoor receives encrypted instructions from the gang via C&C servers, using compromised, kegitimate websites as a proxy.
Another notable similarity between Gazer and past creations of the Turla cyberespionage group become obvious when the malware is analysed. Gazer makes extra efforts to evade detection by changing strings within its code, randomizing markers, and wiping files securely.
In the most recent example of the Gazer backdoor malware found by ESET’s research team, clear evidence was seen that someone had modified most of its strings, and inserted phrases related to video games throughout its code.
Don’t be fooled by the sense of humour that the Turla hacking group are showing here, falling foul of computer criminals is no laughing manner.
All organisations, whether governmental, diplomatic, law enforcement, or in traditional business, need to take today’s sophisticated threats serious and adopt a layered defence to reduce the chances of a security breach.
