Ransomware and what you need to know
- 1. Ransomware and what you need to know
- 2. sca-group.co.uk What is ransomware? • Ransomware is a malicious form of software • It is used to target potentially valuable and precious computer files • The software is designed to gain access to business IT systems and then encrypt them so that they become inaccessible to their owners • Ransomware attackers then demand payments in return for a code that should be the key to then release the encrypted files
- 3. sca-group.co.uk How does it work? • Ransomware is designed to be stealthy and to sneak unnoticed onto a computer or an IT infrastructure • Gaining access via malicious advertisements, a hijacked website or infected email • Usually the ransomware will sit for while on a target system before striking and encrypting files • The encryption process is complicated, typically the only way to unlock files that have been encrypted is to pay the ransom • So prevention is much, much better than cure when it comes to ransomware attacks
- 4. sca-group.co.uk Who gets targeted by ransomware? Anyone can be targeted by a ransomware attack
- 5. sca-group.co.uk Who gets targeted by ransomware? • Anyone can be targeted by a ransomware attack – not only big businesses • SMEs are often considered good targets for ransomware because they have a lot to lose and potentially less robust IT security than their larger counterparts • The amounts demanded by ransomware attackers may be smaller for smaller businesses but the relative impact of the costs involved can be much greater
- 6. sca-group.co.uk Making payments • Ransomware attackers typically want ransoms to be paid in Bitcoins • Bitcoins are a form of digital currency which are very difficult to trace • Demands for a ransomware payment will usually come with a strict deadline and timeframe • Non-payment can result in your files being deleted and rendered completely unrecoverable • Making a payment does not guarantee the return of your files
- 7. sca-group.co.uk Who gets targeted by ransomware? Protect yourself against a ransomware attack
- 8. sca-group.co.uk Protecting yourself against ransomware • Anti-virus software – a quality internet security system can protect your computers and files but not with absolute reliability • External hard drives – Storing important files externally can protect them from ransomware but this method is only as good as your ability to remember to back up your files regularly – hard drives themselves can also be accessed by ransomware attackers • Cloud back up – This is by far the most reliable and effective means of protecting yourself against ransomware attacks
- 9. sca-group.co.uk Finding the right solutions • We at SCA can advise you on how best to protect yourself against ransomware attacks • Cloud-based back up solutions are available for small, medium and large-scale businesses and for anyone concerned about their data security • Cloud options require upfront costs but offer the only guarantee of effective protection against ransomware attacks

The first thing I do with my clients is to focus on what they want to get as a result of working with me.

I’ve worked with coaches and helped them to bring in a million pounds in revenue in a 12 month period and othesr 50K 100K 200K. Some clients want to focus in other areas: presenting, being visible on social media, planning, creating and running a live event, creating their first online programme and selling it. It’s not always about the money but it is about the result.
