In these last few years, the General population have been exposed to a tool Hackers have known for even longer, RANSOMWARE!!! Since its emergence into general pop. we can kindly say it has been a pain in the, well you know, and it doesn’t seem to be letting up anytime soon. Ransomware has steadily evolved over the years, from its deployment to the encryption down to the algorithm have all become so advanced it is becoming harder and harder to recover systems from this digital kidnapping.
Last year’s BIG3 ( WannaCry, NotPetya, BadRabbit) reached out and touched more than 150 countries globally from America down to Spain Over To Turkey to Russia And South Korea, just to name a few. Each of which, exploiting a different vulnerability and then demanding BitCoin to unlocked the encrypted files. There is an excellent video on YouTube that shows how WannaCry goes through the process https://www.youtube.com/watch?v=zgBjes036JA; please give it a look.
One Vulnerability in particular “EternalBlue MS17-010” was a Microsoft vulnerability that worked by exploiting Microsoft Server Messaging Block (SMB). SMB is a file sharing protocol that allows applications on a computer to read and write files and to request services that are on the same network. Even though Microsoft push this Update before WannaCry Spread, like always people didn’t perform the updates, so massive computers were still exploited, and Digital held at Gunpoint.
So Like anybody who owns important information, there is the question of “how can I keep my system safe?” Well, Microsoft has taken the first step in this war against Ransomware to try to alleviate some of the pain of this growing headache. The Latest update to Windows Office 365 has introduced new security features to help lessen the problems of Ransomware as well as other malware.
Below are some of the new features:
File Recovery and Anti-Ransomware
- Files Restore— Microsoft Office 365 now allows users to restore full OneDrive to a previous point in time within the last 30 days. This feature can be used to recover files from accidental mass deletion, file corruption, ransomware or any catastrophic event.
- Ransomware detection & recovery—Office 365 also introduced a new security feature that detects ransomware attacks and alerts you via email, mobile or desktop notification while helping you restore your OneDrive to a point before malware compromised files.
Security and Privacy Features
Office 365 has added three new features to help keep your confidential or personal data (such as tax documents, family budgets, or a new business proposal) secure and private when sharing them online.
- Password protected sharing links— This feature allows you to set a password for your shared files and folders, preventing unauthorized access even if your recipient accidentally forwards protected documents to others.
- Email encryption— This feature allows users to send/receive encrypted end-to-end emails in Outlook through a secure connection, which provides additional protection to minimize the threat of being intercepted.
- Prevent forwarding—Microsoft now lets you prevent your email recipients from distributing or copying emails you export from Outlook. In addition to this, any MS Office attached to your email will remain encrypted even after downloading, so if the recipient shares your attachment with others, they will not be able to open it.
