Unprecedented Office 365 Ransomware Attack Strikes Millions

Microsoft Office productivity tools have long been established as the gold standard for business around the world. They hold a significant presence in the market, with an estimated 80 million users using Office 365, the cloud subscription service providing Office applications.

The sudden emergence of Office 365 ransomware puts those users – and their enterprises – at risk. On June 22 at 6:44 a.m., IT security blogger Steven Toole reported the first attack, which was detected by cloud security firm Avanan.

The attack continued for a week, with Microsoft moving to block the malicious attachment on June 23. At least 57% of all Office 365 customers were hit with at least one phishing attempt.

Zap Zcryptor: Ways to Fight Back

Viruses. Adware. Spyware. Trojan horses. Botnets. Browser hijacking software. Known as malware, all hit today's computers and other devices with a vengeance to cause the maximum damage possible.

Call them what you will, but they all serve a malicious purpose:

  1. They install themselves on computers without approval.
  2. They damage computers in other to steal data, personal or confidential information, passwords, files and Internet traffic. They even go so far as to cause a computer to stop working.
  3. They require IT staff to spend valuable time — time they can't afford to give up — to remove the villain and then fix the damage it's caused.

Plus, they bring in significant profits to their creators. For example, a 2015 Angler exploit kit made an average of $5 million every month they struck.

However, another type of malware is rapidly evolving — and fast. Analysts and researchers are now pinpointing ransomware as the next major threat, and it's going to hit with even more power and efficiency of its cousins.

The relationship between TOR and ransomware

During your travels around the World Wide Web (or if you’re a House of Cards fan), you may have heard the TOR (The Onion Router) network of servers mentioned. This network was initially developed by the U.S. Navy as a way to anonymously browse the Internet. When used in that manner, the TOR network is a great concept and a lifeline for some users. However, for others, TOR is an enigmatic network with suspected links to hackers and other illegal activities.
