Ransomware increasingly dangerous cyber security threat

Ransomware attacks now account for around a quarter of cyber security threats targeting internet users in the UK- according to Eset.

Ransomware attacks now account for around a quarter of cyber security threats targeting internet users in the UK- according to Eset.Eset’s LiveGrid telemetry shows an increase in detections of the JS/Danger.ScriptAttachment malicious code, which tries to download and install various malware variants to the intended victims’ machines.

The majority of the code consists of crypto-ransomware, including some well known groupings, such as Teslacrypt.

The most recent wave of attacks has been focused on victims in the UK, where it accounted for roughly every fourth threat in the third week of April 2016, said the security firm.

“To reach as many potential victims as possible, attackers are spamming inboxes in various parts of the world,” said Ondrej Kubovič, security specialist at Eset. “Therefore, users should be very cautious about which messages they open.”

Meanwhile, the latest Verizon Data Breach Investigations Report (DBIR) also warns that ransomware attacks are steadily increasing.

Laurance Dine, managing principal of investigative response at Verizon Enterprise Solutions, said: “Ransomware is going crazy. It is everywhere. As an incident response team we are dealing with ransomware attacks all the time.”

Eset’s Kubovič recommends that companies should train their employees to report incidents to their internal security departments.

“Users should keep their operating systems and software up to date, as well as install a reliable security suite offering multiple layers of protection and regular updates,” he added.

“Last but not least, users need to back up all their important and valuable data, allowing for its recovery in case of ransomware infection,” he said.

While ransomware is becoming an increasing problem for businesses, a recent spate of attacks on hospitals in the past few months – mainly in the US, but also in Canada, Germany and New Zealand – has underlined the potentially life-threatening impact of ransomware, which works by encrypting data and demanding a ransom to be paid for its release.

The dangers of the IoT

A report by Institute for Critical Infrastructure Technology (ICIT) has also highlighted the fact that internet of things (IoT) devices offer a potential growth opportunity to any ransomware operation, given the devices are interconnected by design and many lack any form of security.

According to the report, while a lot of traditional malware will be too large to ever run on many IoT devices, ransomware (predominantly consisting of a few commands and an encryption algorithm) is much lighter.

Many medical devices, such as insulin pumps and other medication dispersion systems, are internet- or Bluetooth-enabled, the report pointed out, and warned that ransomware could used to open connections to infect the IoT device.

Part of the problem with the security of IoT communications is that the designers are more concerned by the ease of connectivity than the safety of their users.

Cybercrime and cyber security tops business worries for 2016

Cybercrime and cyber security tops business worries for 2016.

Cybercrime and Cyber security tops business worries for 2016This year, cybersecurity will be the main issue worrying global business, firms say, and it will become more critically important as the internet of things takes off and our world becomes ever more mobile and connected.

Lawyers, accountants, digital agencies, research analysts, telecoms and tech firms all gave the BBC’s Technology of Business their views on what the key tech trends were likely to be in 2016.

Here’s a summary of the Top 10 tech trends affecting business in 2016 that emerged:

  1. Cybercrime and a renewed emphasis on cybersecurity
  2. The internet of things and the development of the hyper connected world
  3. Real time data analytics, not intuition, driving business decisions
  4. New data protection laws forcing firms to rethink compliance strategies
  5. Artificial intelligence and robotics replacing repetitive tasks
  6. Smartphones becoming the primary tool for almost everything
  7. More business applications for virtual and augmented reality tech
  8. Increased personalised and in-store location-based marketing
  9. Drones to be allowed to make deliveries and perform other public tasks
  10. Established businesses to face increased competition from start-ups

Allowing customers’ data to be stolen by hackers is not good for business, firms are finally realising. It damages corporate reputations and erodes the public’s “comfort with sharing their data”, says Rashmi Knowles of cybersecurity company RSA.

But the worrying news is that breaches are inevitable, warns Geoff Smith of Experis, while a shortage of skilled cybersecurity professionals is likely to push up the costs of beefing up defences and dealing with attacks.

On top of this, new European data protection laws coming into effect in 2018 will see a “dramatic increase in fines” for data breaches, says James Mullock of law firm Bird and Bird, forcing firms to reassess their compliance procedures this year. Dedicated Data Protection Officers reporting to the board would be “a sensible measure”, he says.

Ransomware is opening up new income for cybercriminals.

Several security experts are forecasting an increase in ransomware attacks, whereby criminals hack into your system, encrypt your data and then demand a ransom before they decrypt it.

“The ransomware arms race will come to the fore in 2016,” says Hitesh Sheth, chief executive of Vectra Networks. “The threat will take on a new, larger role by concentrating attacks on enterprises, holding critical assets hostage in return for even bigger money.”

Other experts warn that the growth of mobile payments systems will offer new opportunities for hackers, while others think criminals will increasingly target employees, suppliers and contractors as a way of infiltrating corporate systems.

Gadgets and objects wirelessly transmitting sensor data to each other and central computers will accelerate in 2016, many believe, leading to a host of new applications – and a host of new cybersecurity threats.

Internet of Things (IOT) cybersecurity concerns will also loom large in 2016.

This new world of “connected everything”, says Tudor Aw, head of technology sector at consultancy KPMG, “should finally see real momentum in 2016”, from connected cars recording driver behaviour data for insurance purposes, to smart watches and other wearables delivering health data and even initial diagnoses.

And all the data that these connected things generate will be stored, analysed and translated into practical insights using real-time analytics, enabling companies to “move beyond just quickly responding to changing customer needs, to actually anticipating those changes,” says Andy Lawson, managing director at Salesforce UK.

But many warn that greater connectivity means more points of entry for hackers constantly on the look out for weak points in any network.
