The WannaCry ransomware campaign wasn’t the first to use the EternalBlue and DoublePulsar exploits. ESET has revealed that they were first used at the end of April when hackers Monero cryptocurrency mining software.
The massive campaign that spread the WannaCry (aka WannaCryptor) ransomware wasn’t the only recent large-scale infection misusing the EternalBlue and DoublePulsar exploits, leaked by Shadow Brokers. The same mechanism was misused by black-hats as early as the end of April, when they opted for the off-the-shelf Monero cryptocurrency mining software, instead of the encrypting payload.
This campaign detected as Win32/CoinMiner.AFR and Win32/CoinMiner.AFU started only a few days after the NSA tools leaked online. ESET had network detections for the vulnerability deployed on April 25th – three days before the first attack attempts by these miners for Monero cryptocurrency.
The biggest uptick was recorded only hours before the mining ransomware’s global outbreak, on May 10th. On that day, mining malware detections increased from hundreds of detections per day to thousands. We have seen such attempts in as many as 118 countries, with Russia, Taiwan and Ukraine topping the list.
However, the mining software consumed system resources so intensely that in some cases it rendered the infected machines unresponsive.
Interestingly the CoinMiner attacks also blocked the 445 port used by the EternalBlue exploit to get into the machine, essentially closing the door to any subsequent infection using the same vector – including WannaCry. If the miners hadn’t taken this precaution, the number of WannaCry infections could have been even greater than reported.
So how bad was the WannaCry attack?
According to ESET telemetry, since Friday, the machines of more than 14.000 users who have enabled ESET LiveGrid, has reported as many as 66.000 WannaCry attack attempts on their devices.
These attacks mainly targeted Russian computers, with over 30.000 attacks, followed by Ukraine and Taiwan, where in both cases they were close to the 8.000 mark.
The chaos that ensued after WannaCry’s global outbreak seems to have motivated other black-hats to scale up their efforts too. We have seen a significant increase in the number of malicious emails sent out by the notorious Nemucod operators, spreading another ransomware.
Also, WannaCry fakes have emerged. These try to ride the wave of its fame by using the same GUI and layout. However, the encrypting capability was missing in all seen instances.
What should you do to stay safe?
- Since the EternalBlue exploit uses a vulnerability in Windows that has been already patched by Microsoft, the first thing would be to verify the completion of the update and the patch to your operating system.
- Use a reliable security solution that utilises multiple layers to protect you from similar threats in the future.
- It is best practice to keep backups on a remote hard disk or location that will not be hit in case of a network infection.
- We recommend that users do not pay ransoms – be it a case of the true WannaCry or any other ransomware. There have been no reported cases where pursuing such a step would lead to decryption. On the contrary, there have been multiple stories documenting the opposite – no decryptor or key being sent after the payment was made. Also, there seems to be no way for the attackers to match the payment to the specific victim who sent it to one of the shared BitCoin wallets.
Millennials turning 40: NOW will you stop targeting them?
It’s one of the most overused terms in youth marketing, and probably the most inaccurate, writes ARTHUR GOLDSTUCK
One of the most irritating buzzwords embraced by marketers in recent years is the term “millennial”. Most are clueless about its true meaning, and use it as a supposedly cool synonym for “young adults”. The flaw in this targeting – and the word “flaw” here is like calling the Grand Canyon a trench – is that it utterly ignores the meaning of the term. “Millennials” are formally defined as anyone born from 1980 to 2000, meaning they have typically come of age after the dawn of the millennium, or during the 21st century.
Think about that for a moment. Next year, the millennial will be formally defined as anyone aged from 20 to 40. So here you have an entire advertising, marketing and public relations industry hanging onto a cool definition, while in effect arguing that 40-year-olds are youths who want the same thing as newly-minted university graduates or job entrants.
When the communications industry discovers just how embarrassing its glib use of the term really is, it will no doubt pivot – millennial-speak for “changing your business model when it proves to be a disaster, but you still appear to be cool” – to the next big thing in generational theory.
That next big thing is currently Generation Z, or people born after the turn of the century. It’s very convenient to lump them all together and claim they have a different set of values and expectations to those who went before. Allegedly, they are engaged in a quest for experience, compared to millennials – the 19-year-olds and 39-olds alike – supposedly all on a quest for relevance.
In reality, all are part of Generation #, latching onto the latest hashtag trend that sweeps social media, desperate to go viral if they are producers of social content, desperate to have caught onto the trend before their peers.
The irony is that marketers’ quest for cutting edge target markets is, in reality, a hangover from the days when there was no such thing as generational theory, and marketing was all about clearly defined target markets. In the era of big data and mass personalization, that idea seems rather quaint.
Indeed, according to Grant Lapping, managing director of DataCore Media, it no longer matters who brands think their target market is.
“The reason for this is simple: with the technology and data digital marketers have access to today, we no longer need to limit our potential target audience to a set of personas or segments derived through customer research. While this type of customer segmentation was – and remains – important for engagements across traditional above-the-line engagements in mass media, digital marketing gives us the tools we need to target customers on a far more granular and personalised level.
“Where customer research gives us an indication of who the audience is, data can tell us exactly what they want and how they may behave.”
Netflix, he points out, is an example of a company that is changing its industry by avoiding audience segmentation, once the holy grail of entertainment.
In other words, it understands that 20-year-olds and 40-year-olds are very different – but so is everyone in between.

Robots coming to IFA
Robotics is no longer about mechanical humanoids, but rather becoming an interface between man and machine. That is a key message being delivered at next month’s IFA consumer electronics expo in Berlin. An entire hall will be devoted to IFA Next, which will not only offer a look into the future, but also show what form it will take.
The concepts are as varied as the exhibitors themselves. However, there are similarities in the various products, some more human than others, in the fascinating ways in which they establish a link between fun, learning and programming. In many cases, they are aimed at children and young people.
The following will be among the exhibitors making Hall 26 a must-visit:
Leju Robotics (Stand 115) from China is featuring what we all imagine a robot to be. The bipedal Aelos 1s can walk, dance and play football. And in carrying out all these actions it responds to spoken commands. But it also challenges young researchers to apply their creativity in programming it and teaching it new actions. And conversely, it also imparts scholastic knowledge.
Cubroid (Stand 231, KIRIA) from Korea starts off by promoting an independent approach to the way it deals with tasks. Multi-functional cubes, glowing as they play music, or equipped with a tiny rotating motor, join together like Lego pieces. Configuration and programming are thus combined, providing a basic idea of what constitutes artificial intelligence.
Spain is represented by Ebotics (Stand 218). This company is presenting an entire portfolio of building components, including the “Mint” educational program. The modular system explains about modern construction, programming and the entire field of robotics.
Elematec Corporation (Stand 208) from Japan is presenting the two-armed SCARA, which is not intended to deal with any tasks, but in particular to assist people with their work.
Everybot (Stand 231, KIRIA) from Japan approaches the concept of robotics by introducing an autonomous floor-cleaning machine, similar to a robot vacuum cleaner.
And Segway (Stand 222) is using a number of products to explain the modern approach to battery-powered locomotion.
IFA will take place at the Berlin Exhibition Grounds (ExpoCenter City) from 6 to 11 September 2019. For more information, visit www.ifa-berlin.com
