Wannacry still alive

One and a half years after its epidemic, WannaCry ransomware tops the list of the most widespread cryptor families and the ransomware has attacked 74,621 unique users worldwide.

These attacks accounted for 28.72% of all users targeted by cryptors in Q3 2018. The percentage has risen over the last year, demonstrating more than two thirds growth against Q3 2017, when its share in cryptor attacks was 16.78%. This is just one of the main findings from Kaspersky Lab’s Q3 IT threat evolution report. 

A series of cyberattacks with WannaCry cryptor occurred in May 2017 and is still considered to be one of the biggest ransomware epidemics in history. Even though Windows released a patch for its operating system to close the vulnerability exploited by EternalBlue 2 months prior to the start of the attacks, WannaCry still affected hundreds of thousands devices around the globe. As cryptors do, WannaCry turned files on victims’ computers into encrypted data and demanded ransom for decryption keys (created by threat actors to decipher the files and transform them back into the original data) making it impossible to operate the infected device.

The consequences of the WannaCry epidemic were devastating: as the victims were mainly organisations with networked systems – the work of businesses, factories and hospitals was paralysed. Even though this case demonstrated the dangers cryptors pose, and most of PCs around the world have been updated to resist the EternalBlue exploit, the statistics show that criminals still try to exploit those computers that weren’t patched and there are still plenty of them around the globe.

Overall, Kaspersky Lab security solution protected 259,867 unique users from cryptors attacks, showing a substantial rise of 39% since Q2 2018, when the figure was 158,921. The growth was rapid yet steady, with a monthly observed increase in the number of users.

The rising share of WannaCry attacks is another reminder that epidemics don’t end as fast as they start – there are always long-running consequences. In the case of cryptors, attacks can be so severe that it is necessary to take preventive measures and patch the device, rather than deal with encrypted files later,” said Fedor Sinitsyn, security researcher at Kaspersky Lab.

 To reduce the risk of infection by WannaCry and other cryptors, users are advised to:

  • Always update your operating system to eliminate recent vulnerabilities and use a robust security solution with updated databases. It is also important to use the security solution that has specialised technologies to protect your data from ransomware, as Kaspersky Lab’s solutions do. Even if the newest yet unknown malware does manage to sneak through, Kaspersky Lab’s System Watcher technology is able to block and roll back all malicious changes made on a device, including the encryption of files.
  • If you have bad luck and all your files are encrypted with cryptomalware, it is not recommended to pay cybercriminals, as it encourages them to continue their dirty business and infect more people’s devices. It is better to find a decryptor on the Internet – some of them are available for free here: https://noransom.kaspersky.com/

·         It is also important to always have fresh backup copies of your files to be able to replace them in case they are lost (e.g. due to malware or a broken device), and store them not only on the physical object but also in cloud storage for greater reliability (don’t forget to protect your cloud storage with strong hack-proof password!)

·         If you’re a business, enhance your preferred third-party security solution with the newest version of the free Kaspersky Anti-Ransomware Tool.

·         To protect the corporate environment, educate your employees and IT teams, keep sensitive data separate, restrict access, and always back up everything.

·         Use a dedicated security solution, such as Kaspersky Endpoint Security for Business that is powered by behaviour detection and able to roll back malicious actions. It should also include Vulnerability and Patch management features that automatically eliminates vulnerabilities and installs updates. This reduces the risk of vulnerabilities in popular software being used by cybercriminals.

·         Last, but not least, remember that ransomware is a criminal offence. You shouldn’t pay. If you become a victim, report it to your local law enforcement agency.

Earth 2050: memory chips for kids, telepathy for adults

An astonishing set of predictions for the next 30 years includes a major challenge to the privacy of our thoughts.

Published

on

By 2050, most kids may be fitted with the latest memory boosting implants, and adults will have replaced mobile devices with direct connectivity through brain implants, powered by thought.

These are some of the more dramatic forecasts in Earth 2050, an award-winning, interactive multimedia project that accumulates predictions about social and technological developments for the upcoming 30 years. The aim is to identify global challenges for humanity and possible ways of solving these challenges. The website was launched in 2017 to mark Kaspersky Lab’s 20th birthday. It comprises a rich variety of predictions and future scenarios, covering a wide range of topics.

Recently a number of new contributions have been added to the site. Among them Lord Martin Rees, the UK’s Astronomer Royal, Professor at Cambridge University and former President of the Royal Society; investor and entrepreneur Steven Hoffman, Peter Tatchell, human rights campaigner, along withDmitry Galov, security researcher and Alexey Malanov, malware analyst at Kaspersky Lab.

The new visions for 2050 consider, among other things:

  • The replacement of mobile devices with direct connectivity through brain implants, powered by thought – able to upload skills and knowledge in return – and the impact of this on individual consciousness and privacy of thought.
  • The ability to transform all life at the genetic level through gene editing.
  • The potential impact of mistakes made by advanced machine-learning systems/AI.
  • The demise of current political systems and the rise of ‘citizen governments’, where ordinary people are co-opted to approve legislation.
  • The end of the techno-industrial age as the world runs out of fossil fuels, leading to economic and environmental devastation.
  • The end of industrial-scale meat production, as most people become vegan and meat is cultured from biopsies taken from living, outdoor reared livestock.

The hypothetical prediction for 2050 from Dmitry Galov, security researcher at Kaspersky Lab is as follows: “By 2050, our knowledge of how the brain works, and our ability to enhance or repair it is so advanced that being able to remember everything and learn new things at an outrageous speed has become commonplace. Most kids are fitted with the latest memory boosting implants to support their learning and this makes education easier than it has ever been. 

“Brain damage as a result of head injury is easily repaired; memory loss is no longer a medical condition, and people suffering from mental illnesses, such as depression, are quickly cured.  The technologies that underpin this have existed in some form since the late 2010s. Memory implants are in fact a natural progression from the connected deep brain stimulation implants of 2018.

“But every technology has another side – a dark side. In 2050, the medical, social and economic impact of memory boosting implants are significant, but they are also vulnerable to exploitation and cyber-abuse. New threats that have appeared in the last decade include the mass manipulation of groups through implanted or erased memories of political events or conflicts, and even the creation of ‘human botnets’. 

“These botnets connect people’s brains into a network of agents controlled and operated by cybercriminals, without the knowledge of the victims themselves.  Repurposed cyberthreats from previous decades are targeting the memories of world leaders for cyber-espionage, as well as those of celebrities, ordinary people and businesses with the aim of memory theft, deletion of or ‘locking’ of memories (for example, in return for a ransom).  

“This landscape is only possible because, in the late 2010s when the technologies began to evolve, the potential future security vulnerabilities were not considered a priority, and the various players: healthcare, security, policy makers and more, didn’t come together to understand and address future risks.”

How load-shedding is killing our cellphone signals

Published

on

Extensive load-shedding, combined with the theft of cell tower backup batteries and copper wire, is placing a massive strain on mobile network providers.

MTN says the majority of MTN’S sites have been equipped with battery backup systems to ensure there is enough power on site to run the system for several hours when local power goes out and the mains go down. 

“With power outages on the rise, these back-up systems become imperative to keeping South Africa connected and MTN has invested heavily in generators and backup batteries to maintain communication for customers, despite the lack of electrical power,” the operator said in a statement today.

However, according to Jacqui O’Sullivan, Executive: Corporate Affairs, at MTN SA, “The high frequency of the cycles of load shedding have meant batteries were unable to fully recharge. They generally have a capacity of six to 12 hours, depending on the site category, and require 12 to 18 hours to recharge.”

An additional challenge is that criminals and criminal syndicates are placing networks across the country at risk. Batteries, which can cost R28 000 per battery and upwards, are sought after on black markets – especially in neighbouring countries. 

“Although MTN has improved security and is making strides in limiting instances of theft and vandalism with the assistance of the police, the increase in power outages has made this issue even more pressing,” says O’Sullivan.

Ernest Paul, General Manager: Network Operations at SA’s leading network provider MTN, says the brazen theft of batteries is an industry-wide problem and will require a broader initiative driven by communities, the private sector, police and prosecutors to bring it to a halt.

“Apart from the cost of replacing the stolen batteries and upgrading the broken infrastructure, communities suffer as the network degrades without the back-up power. This is due to the fact that any coverage gaps need to be filled. The situation is even more dire with the rolling power cuts expected due to Eskom load shedding.”

Loss of services and network quality can range from a 2-5km radius to 15km on some sites and affect 5,000 to 20,000 people. On hub sites, network coverage to entire suburbs and regions can be lost.
