WannaCry Ransomware

Aaaand we’re back! No prizes for guessing the topic of our latest blog entry! The NHS has been targeted by a piece of ‘Ransomware’ known as WannaCry. The centrepiece of this attack is the encryption of all their data. The actual virus is fairly easy to remove, but the damage is done by way of encrypting any data on an infected machine with an encryption key held only by the designers of the ransomware. A ransom is then sought for the encrypted data. Microsoft Windows operating systems are currently only affected, but it is worth keeping all operating systems updated. Modern Windows operating systems are protected by way of security updates. Windows XP, which most, if not all, of the NHS runs on, is no longer supported by Microsoft. Therefore, if you are running Windows XP, you are putting yourself at risk, and we advise that you upgrade your computer to a later operating system as soon as possible


Malicious Software

The internet is a dangerous place. There is no denying it. However, at the same time, it is a wonderful source of information. In order to stay safe on the internet, it is important to not click, or install, any software that can compromise your computer.

While researching for this post, I found a video on YouTube from Jim Browning. In this short film, he explains how a particular piece of software, known as ‘System Diagnostic Tool’ defrauds it’s customers. The ‘program’ in question, reports to remove, or clean, your PC of infections and junk. In reality, it does nothing. The video is well worth a watch.

System Diagnostic Tool is a product of Sparksgen Limited, retailing through http://www.safeapzz.com, who are both well known within the IT industry as fraudsters. Please do not install this, or any of their software mentioned in the video. Should you have already installed this, or any of their software, please remove it immediately and run an antivirus/anti-malware scan of your computer.

Autofill Vulnerability

Today brought news of another danger to our online security. Finnish web developer and hacker Viljami Kuosmanen discovered that several web browsers, including Google’s Chrome, Apple’s Safari and Opera, as well as some plugins and utilities such as LastPass, can be fooled into giving away your personal information through their autofill systems.

Many people around the world use the autofill feature of the browsers mentioned above. While it is a handy convenience, the risk of giving away your data must surely outweigh the time taken to fill in your email, or postal address.

Users of Mozilla’s Firefox browser are safe, as the program doesn’t offer an autofill feature.

We are advising users to disable the autofill feature on the browsers we have outlined, until a fix is released.
