At the beginning of this year a US study found that Ransomware attacks quadrupled in 2016 and predicted that they will double again in 2017. Chillingly, bearing in mind the events of the last few days particularly involving many NHS trusts, the report also warned that the threat from Ransomware was not only growing, but evolving to allow hackers to target vulnerable organisations.
The study also found that hacks and malware accounted for 40 percent of data breaches at financial institutions in 2016, up from 27 percent in 2015. Caroline Howell, founder of PuterTutor Computer Services, is no stranger to Ransomware attacks and has been approached by several bereft companies after their entire systems had been encrypted. Caroline says, “nobody recommends that anyone pay the ‘ransom’ to get their files back but often people are so desperate to try and retrieve many years of work or personal folders that they will pay – and the criminals know this, which is why Ransomware is growing and evolving so fast.
Of course the best thing to do is make sure that you cannot become infected and that is by having the right Anti-virus protection. Only around 30% of Anti-malware software was able to stop the latest Ransomware attack and the vast majority of current infections are happening on systems ‘protected’ by sub-standard programmes”.
Caroline adds, “It is very important that you have some good anti-virus software installed on your computers and servers to keep this threat at bay. The cost of anti-virus protection against the damage a virus or Ransomware could do is incredibly small and yet small business’ still try to get by. This is a false economy and the small initial cost far outweighs the loss you or your company would suffer should its systems be brought down by a virus.
The 2nd best way of dealing with the threat is to make sure there isn’t actually a threat at all by having a robust back up plan in place. Not only backup BUT it has to be working. There is no point in having a backup to then discover you can’t restore your files or device. Why would you pay a ransom on files on which you already have full back ups?”
Remember there is a huge difference between a backup solution and using storage such as Dropbox or One Drive. If you use these and you get infected anyone who has the files shared can potentially infect the other users sharing those files. While these solutions are excellent storage for sharing files they still need to be backed up – Can your backup do this?
Caroline has listed some key points which everyone – individuals and businesses – can do to protect themselves against the threat of Ransomware –
Have a current, working backup strategy
Most viruses and Ransomware will infect systems via email attachments or infected websites.
Cyber criminals like to make use of social media platforms of the accounts of your friends, family, or colleagues to send you malicious links masked as harmless ones. Do not to open ANY email attachments from addresses you don’t know. If it appears from someone you do know, it is best to check with that person first if you have your suspicions. Also beware of fake emails appearing as online banks, HMRC etc. These are likely to include malware-ridden links in order to release it into your system to seize control of it. This process is called Phishing. Remember HMRC DO NOT send emails, most banks DO NOT send emails, if it’s too good to be true it’s probably not true. An even better solution is to have a robust and reliable email filtering program so all the junk and potential threats are stopped before appearing in your inbox
Whatever happens, this threat is not going away and new infections – and probably cleverer ones – will occur. Be aware, be smart and keep up to date with these type of threats …..or find a good IT Company to do it for you. Think what your family photos are worth to you or all the hard work you’ve put into building that business over the last few years? If you don’t spend time and probably money protecting yourself properly now, then the alternative can be very costly indeed – in more ways than one.
