Free key for ransomware

Published

on

The Belgian Federal Police has released free decryption keys for the Cryakl ransomware, after working in close cooperation with Kaspersky Lab.

The keys were obtained during an ongoing investigation; and by sharing the keys with No More Ransom the Belgian Federal Police becomes a new associate partner of the project – the second law enforcement agency to do so after the Dutch National Police.

In the last few years, ransomware has eclipsed most other cyber threats, with global campaigns now indiscriminately affecting organisations across multiple industries in both the public and private sectors, as well as consumers. One of the most effective ways to fight ransomware is to prevent it. This is exactly why No More Ransom was launched more than a year ago.

Today sees yet another successful example of how cooperation between law enforcement and internet security companies can lead to great results. When the Belgian Federal Computer Crime Unit (FCCU) discovered that Belgian citizens had been victims of the Cryakl ransomware, it was able to locate a command and control server in one of Belgium’s neighbouring countries. Led by the federal prosecutor’s office, the Belgian authorities seized this and other servers while forensic analysts worked to retrieve the decryption keys. Kaspersky Lab provided technical expertise to the Belgian federal prosecutor and has now added these keys to the No More Ransom portal on behalf of the Belgian Federal Police. This will allow victims to regain access to their encrypted files without having to pay the criminals.

The Belgian authorities have continued with their investigation.

“Our regular advice in the case of ransomware attacks is: please don’t pay the ransom. A number of cyber security experts work worldwide to help the victims, creating new, previously non-existent tools for decryption. Free decryption keys for Cryakl ransomware can be considered as proof of this policy and yet another reminder that there is always a chance of winning in the fight with criminals,” said Jornt van der Wiel, Security Researcher in the Global Research and Analysis Team at Kaspersky Lab. 

52 decryption tools available

Since the launch of the No More Ransom portal in July 2016, almost 1.6 million people from more than 180 countries have accessed the website, available in 29 languages with Estonian as the most recent addition.

There are now 52 free decryption tools on www.nomoreransom.org, which can be used to decrypt 84 ransomware families. CryptXXX, CrySIS and Dharma are the most detected infections. More than 35,000 people have managed to retrieve their files for free, which has prevented criminals from profiting from more than EUR 10 million.

The number of partners working together on No More Ransom has risen to more than 120, including more than 75 internet security companies and other private partners. The Cypriot and Estonian police forces are the latest law enforcements agencies to join. KPN, Telenor and The College of Professionals in Information and Computing (CPIC) have also joined as new private sector partners.

Personal computing devices sales still decline in MEA

Published

on

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.

Middle East & Africa PC Market Vendor Shares – Q2 2016 vs. Q2 2017

Brand Q2 2016 Q2 2017
HP Inc. 23.7% 27.6%
Lenovo 19.8% 21.5%
Dell 16.3% 16.7%
ASUS 8.7% 9.4%
Acer Group 5.9% 4.1%
Others 25.7% 20.7%

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.

Middle East & Africa Tablet Market Vendor Shares – Q2 2016 vs. Q2 2017

Brand Q2 2016 Q2 2017
Samsung 20.5% 18.9%
Huawei 11.2% 15.8%
Lenovo 12.7% 9.8%
Apple 9.1% 8.8%
Alcatel 2.9% 5.0%
Others 43.5% 41.7%

“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

Published

on

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.
