Kaspersky Lab’s researchers have discovered a new botnet that cashes-in on aggressive advertising, mostly in Germany and the US. Criminals infect their victims’ computers with the Magala Trojan Clicker, generating fake ad views, and making up to 350$ from each machine.
Contextual online advertising is a lifesaver for small enterprises that are usually unable to promote their products and services and increase potential customer awareness in other ways. The most common way to build a channel of supply and communication for these organisations is to purchase ads from legal advertising companies. However, if the latter are unscrupulous, small companies will flush money down the drain, and customers simply will not see the ad. This is exactly what happens with the Magala botnet.
Its authors compromise computers with malware, which then generates fake views and clicks for ads, thus switching machines into zombie mode and making a profit for the malware’s authors. Once propagated, Magala imitates a user click on a particular webpage, boosting ad click counts. The main victims are those paying for the ad; typically, they are small enterprise owners dealing with fraudulent advertisers.
The Magala infection vector is quite simple – it propagates computers via compromised websites and discreetly installs its required adware. Magala then contacts the remote server and requests a list of search queries for click counts that need to be boosted. Using this list, the programme begins to send search queries and click on each of the first 10 links in the search results, with an interval of 10 seconds between each click.
According to Kaspersky Lab’s researchers, an average cost per click (CPC) in a campaign like this is 0.07 USD. The cost per thousand (CPM) comes to 2.2 USD. Ideally, a botnet consisting of 1000 infected computers clicking 10 website addresses from each search result, and performing 500 search requests with no overlaps in the search results, could ideally mean the virus writer earns up to 350 USD from each infected computer.
“Although this type of advertising fraud has long been known, the emergence of new botnets focusing on that area indicates that there is still a demand on half-legitimate promotion. Trying to cut their costs, small businesses go for that option, but spoil their ad efforts as a result. The success of Magala is yet another wake-up call for users to make the most of solid security solutions and keep all their software updated – in order to not fall victim to cybercriminals,” concludes Sergey Yunakovsky, security expert at Kaspersky Lab.

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.
