Ransomware stops you from using your PC. It holds your PC or files for "ransom". This information describes what ransomware is and what it does, and provides advice on how to prevent and recover from ransomware infections.
What does ransomware do?
There are different types of ransomware. However, all of them will prevent you from using your PC normally, and they will all ask you to do something before you can use your PC.
They can target any PC users, whether it’s a home computer, business computers in network, or servers in a business environment.
Ransomware will demand that you pay money (a “ransom”) to get access to your PC or files. We have also seen them make you complete surveys. There is no guarantee that paying the fine or doing what the ransomware tells you will give access to your PC or files again.
That’s why the best solution to ransomware is to be safe on the Internet and with emails. Don’t click on a link on a webpage or in an email. If you’re ever unsure – don’t click it! Contact your support team at Oltech Office Logics Ltd and we will make the call.
Often fake emails and webpages have bad spelling, or just look unusual. They can also look very realistic with official logos such as your bank or government departments. Look out for strange spellings of company names (like “PayePal” instead of “PayPal”) or unusual spaces, symbols, or punctuation (like “iTunesCustomer Service” instead of “iTunes Customer Service”).
Details For Business
The number of business victims being targeted by ransomware is increasing. Usually, the attack occurs when an end user opens an attachment in an email believing it to be from a legitimate source or if the email claims to be from an authority such as An Garda Siochana. Links in emails to compromised websites can also lead to a ransomware attack.
The sensitive files are encrypted, and large amounts of money (up to 250,000 euro) are demanded to restore the files. Generally, the attacker has a list of file extensions or folder locations that the ransomware will target for encryption. Due to the encryption of the files, it can be practically impossible to reverse-engineer the encryption or “crack” the files without the original encryption key – which only the attackers will have access to.
The best advice for prevention is to ensure company-confidential, sensitive, or important files are securely backed up in a remote backup or local storage facility. Business managers and owners are also advised to speak with the team at Oltech Office Logics Ltd. about back up and security solutions.
Globally, ransomware continues to be a major problem for all types of businesses. We’ve seen huge increases in businesses in EU countries becoming primary targets for criminals. The past six months (between December 2015 and July 2016) have seen the highest levels of ransomware distribution. This trend shows no signs of slowing. Oltech Office Logics Ltd. is always available to support you through attacks or discuss prevention measures.
