12 May 2017 | Cryptolocker affects NHS | Camtek CSI

A version of cryptolocker called Wanacrypt0r 2.0 has affected large parts of the NHS today, together with other organisations like Telefonicia. This is ransomware that gets into your IT system (often by invitation) and encrypts all data files and demands money to provide the encryption key. It is difficult to get your files back in 95% of cases, but there are ways of protecting against it - although no one is ever 100 per cent safe. That is why we tell people to keep several backups and have a cyber security regime.

Update: Microsoft issues 'highly unusual' Windows XP patch to prevent massive ransomware attack. Windows XP ceased to get support on 8 April 2014 including program patches. You should be using a later supported operating system to help prevent these attacks. The Microsoft story on this link.

14 March 2017 | Experts warn on rise of hacker ransoms | National Crime Agency UK

According to the UK's National Crime Agency (NCA) smartphones, watches, televisions and fitness trackers can be used to hold people to financial ransom over personal data. Ransomware works by making devices unusable until a ransom is paid to unlock them. To combat this as far as mobile devices are concerned it is important to back up data such as photographs and audio files either to a cloud store or a locally attached flash drive. Many devices also use GPS to track the whereabouts of the phone owner, it is advisable to switch off the location app on a mobile phone when not using the function for mapping or locating apps. This will also save battery power. If you have concerns about your smart tv, then just turn it off and pull the plug out! Ransomware is on the rise, and has been prevalent over the last year. For desktops and lap-tops it is important to keep anti-virus definitions up-to-date together with any other anti-malware programme that you use. Back your data up to a removable hard drive on a regular basis. And, on occassions actually keep an image of your main system drive. If you require any assistance contact us on the number above or by email.

5 January 2017 | How to see if your Netflix account has been hacked | Netflix

There are many reasons social media applications get hacked. It may be friends knowing your passwords, criminals using other information or carrying out 'brute force attacks' to gain access to your personal content.

Recently some Netflix customers have had their Netflix accounts hacked. Netflix credentials are often stolen and sold to other markets.

The easiest way to check this is to go to your account and check your primary profile and check your viewing activity. Here you will see a list of everything you have watched - note this could be any authorised viewer on any of your devices, such as main TV and tablets or phones. Also check to see whether your 'language' interface has been changed.

Finally if you are suspicious then (1) Go to 'my account' page and click on 'sign out of all devices' which will clear credentials on all the devices you (and others) have used requiring a fresh log on. (2) Change your password to a strong one using a mix of letters, numbers and symbols and not one you use on other accounts.
