According to Kaspersky, cybercriminals have started using sophisticated infection methods and techniques borrowed from targeted attacks in order to install mining software on attacked PCs within organisations. The most successful group observed by Kaspersky Lab earned at least $7 million by exploiting their victims in just six months during 2017.
Although the cryptocurrency market is experiencing plenty of ups and downs, last year’s phenomena with surges in the value of Bitcoin has significantly changed not only global economics, but the world of cybersecurity as well. With the aim of earning cryptocurrency, criminals have started to use mining software in their attacks, which, like ransomware, has a simple monetisation model. But, unlike ransomware, it doesn’t destructively harm users and is able to stay undetected for a long time by silently using the PC’s power. Back in September 2017, Kaspersky Lab recorded a rise of miners that started actively spreading across the world, and predicted its further development. The latest research reveals that this growth has not only continued, but has also increased and extended.
Kaspersky Lab researchers recently identified a cybercriminal group with APT-techniques in their arsenal of tools to infect users with miners. They have been using the process-hollowing method that is usually used in malware and has been seen in some targeted attacks of APT actors, but has never been observed in mining attacks before.
The attack works in the following way: the victim is lured into downloading and installing an advertisement software with the miner installer hidden inside. This installer drops a legitimate Windows utility, with the main purpose being to download the miner itself from a remote server. After its execution, a legitimate system process starts, and the legitimate code of this process is changed to malicious code. As a result, the miner operates under the guise of a legitimate task, so it will be impossible for a user to recognise if there is a mining infection. It is also challenging for security solutions to detect this threat. In addition, miners mark this new process through the way it restricts any task cancellation. If the user tries to stop the process, the computer system will reboot. As a result, criminals protect their presence in the system for a longer and more productive time.
Based on Kaspersky Lab’s observations, the actors behind these attacks have been mining Electroneum coins and earned almost $7 million during the second half of 2017, which is comparable to the sums that ransomware creators used to earn.
“We see that ransomware is fading into the background, instead giving way to miners. This is confirmed by our statistics, which show a steady growth of miners throughout the year, as well as by the fact that cybercriminals groups are actively developing their methods and have already started to use more sophisticated techniques to spread mining software. We have already seen such an evolution – ransomware hackers were using the same tricks when they were on the rise,” said Anton Ivanov, Lead Malware Analyst at Kaspersky Lab.
Overall, 2.7 million users were attacked by malicious miners in 2017, according to Kaspersky Lab data. That is approximately 50% higher than in 2016 (1.87 mln). They have been falling victims as a result of adware, cracked games and pirated software used by cybercriminals to secretly infect their PCs. Another approach used was web mining through a special code located in an infected web page. The most widely used web miner was CoinHive, discovered on many popular websites.
In order to stay protected, Kaspersky Lab recommends that users do the following:
- Don’t click on unknown websites, or suspicious banners and ads;
- Do not download and open unknown files from untrusted sources;
- Install a reliable security solution such as Kaspersky Internet Security or Kaspersky Free that detects and protects you from all possible threats, including malicious mining software.
For organisations, Kaspersky Lab recommends the following:
- Carry out a security audit on a regular basis
- Install a reliable security solution on all workstations and servers and make sure all its components are enabled to ensure the maximum protection. Kaspersky Lab customers are protected with Kaspersky Endpoint Security for Business.
Data journalism takes top prize in revamped awards
The entries to the 2018 Vodacom Journalist of the Year Awards were extraordinarily varied and of an excellent standard, with new categories introduced which are based on content as opposed to platforms. This year, the judges decided that two entries were equally worthy of the coveted Vodacom Journalist of the Year Award.
The first co-winning entry, in the new Data Journalism category, is a set of stories by Alastair Otter and Laura Grant of Media Hack which showed how Data Journalism is shaping the future. The second co-winning entrant is Bongani Fuzile of the Daily Dispatch for his articles in the investigative category on how migrant workers were being ripped off by pension deductions (full citations below).
Convenor of the judging panel Ryland Fisher says: “This year we modernised the 12 categories that journalists could enter their work in and the change was embraced by entrants. In a turbulent time for media, the 2018 entries once again proved that there are excellent South African journalists delivering praiseworthy work, and we commend them for finding new and innovative ways to cover the news.”
Takalani Netshitenzhe, Chief Officer for Corporate Affairs at the Vodacom Group, says: “Vodacom is proud of its 17-year association with these prestigious awards, which make an important contribution to our society through the recognition of journalistic excellence. I’d like to congratulate all of tonight’s winners and, as always, I’d like to pay tribute to our hardworking judges. Ryland Fisher, Mathatha Tsedu, Arthur Goldstuck, Collin Nxumalo, Elna Rossouw, Patricia McCracken, Megan Rusi, Mary Papayya, Albe Grobbelaar and Obed Zilwa: thank you for making these awards a continued success.”
Veteran journalist and media stalwart Ms Amina Frense is the winner of the 2018 Vodacom Journalist of the Year Lifetime Achiever Award. She has spent decades in mainstream media both locally and internationally. She is a former Managing Editor: News and Current Affairs at the SA Broadcasting Corporation. She has worked in many countries abroad as a producer and a foreign correspondent, has written two books and is also a founding member of SANEF where she still serves as a council member (full citation below).
The overall winners share the R100 000 main prize. National winners in the various categories are as follows, with each winner taking home R10 000:
The entries in this category were of an exceptionally high standard. One entrant stood out and became the unanimous winner. This journalist showed an exceptional skill for story-telling and for finding unexpected angles and unknown facts. For his stories about Musangwe’s fight for recognition, Age cheating in SA football, and Hansie Cronje revisited, the winner is Ronald Masinda, and the team of Gift Kganyago, Nceba Ntlanganiso and Charles Lombard from eSAT TV.
Cons exploit Telegram ICO
Kaspersky Lab researchers have uncovered dozens of highly convincing fake websites claiming to be investment sites for an initial coin offering (ICO) by the Telegram messaging service. Many of these websites appear to belong to the same group. In one case alone, tens of thousands of US dollars’ worth of cryptocurrency were stolen from victims believing they were investing in ‘Grams’, Telegram’s rumoured new currency. Telegram has not officially confirmed an ICO and has warned people about fraudulent investor sites.
In late 2017, stories started to circulate that the Telegram messaging service was launching an initial coin offering (ICO) to finance a blockchain platform based on its TON (Telegram Open Network) technology. Unverified technical documentation was posted online, but there appears to have been no confirmation from Telegram itself. The resulting confusion seems to have allowed fraudsters to capitalise on investor interest by creating fake sites and stealing vast sums of money.
Kaspersky Lab researchers have discovered dozens of such sites, possibly belonging to the same group, claiming to sell tokens for ‘Grams’ and inviting investors to pay with cryptocurrencies including Bitcoin, Ethereum, lice litecoin, dash and Bitcoin dash. A record of transactions on one site revealed that the scammers were able to steal at least $35,000 US dollars’ worth of Ethereum from investors.
The researchers found that some of the websites were so convincing that even after Telegram and others began to issue warnings, they were still able to recruit potential investors. Most use a secure connection, require registration and generate a unique online wallet for each new victim, making it harder to track the money.
Judging by the content of the fake websites, it appears they may have common ownership. For example, several have the exactly the same ‘Our Team’ section.
“ICOs are a fairly risky investment and many people don’t yet fully understand how they work, so it is not surprising that high quality fake websites, with seemingly reassuring features such as a secure connection and registration are successful at luring people in. People wishing to invest in an ICO would do well to check with the company behind it and make sure they know exactly who they are giving their money to, or they may never see it again,” said Nadezhda Demidova, Lead Web-Content Analyst, Kaspersky Lab.
Kaspersky Lab offers the following advice for users considering investing in an ICO:
- Check for warning signs: for example, some of the fake Telegram ICO websites had the same wrong image next to the name of Telegram’s Chief Product Officer.
- Do your homework: always check with the brand’s official site to verify the legitimacy of the investment site and, if necessary contact the company’s ICO teams before investing any money or currency.
- Use reliable security solutions such as Kaspersky Internet Security and Kaspersky Internet Security for Android, which will warn you if you try to visit fake internet pages.
