Ransomware Attack with Microsoft Office 365

The Ransomware attack

Recently, a new Zero-Day attack has been found, where millions of Microsoft Office 365 users became the victim of this Massive Ransomware attack. The app always pops a warning message which fooled many users by just telling them that there files are encrypted, which needs to be decrypted, not really but only to fool the users. The Ransomware asks for some bitcoins(around 1.3 bit coins) to decrypt the file, and the ransom warning includes a sound message too. Now I guess you also got what a Ransomware.

And you all are very curious about that, how they spread the malware into millions of systems. The technique is simple, as most of the hackers do. They phised those users via spamming emails and targeted those documents which opens through Microsoft Office 365 in their system. Those email attatchments also included a very nasty virus called cerber(a type of Ransomware ). Actually, the malware was first detected by Avanan’s Steven Toole, a researcher of cloud security on June 22. According to him Microsoft took more than 24 hours to detect and block the attack. Also, it was found that 57% of  organizations using Microsoft Office 365 got at least one Ransomware mail.

According to an IDT911 survey, it was found that 84% of the participants won’t pay the ransom, which is a good thing. Only 10% of them said that they would pay between 10$ to 100$ for decrypting those files and 3% would pay 10,000$ or more.
