Ransomware Evolutions And Derivatives

With the latest CyberheistNews Volume being released on the 15th of August, we at MTBW Services thought it would be beneficial to provide a summary of the latest Ransomware activities and a link to the full report.

Some of the more worrisome findings in the report:

  • The FBI projected that the losses caused by ransomware infections could reach a billion dollars in 2016 alone.
  • Late July, thousands of legit WordPress business sites were hijacked by a botnet named SoakSoak to deliver ransomware to anyone who visits their website.
  • Ransomware upgraded strains and rebranded versions sold cheaply on the Dark Web.
  • Stampado was heavily advertised in the cybercrime underground for a fraction of the price of malware typically sold in the Ransomware-as-a-Service market at 39 bucks, with training videos that show how it works.
  • cuteRansomware using Google Docs and other cloud apps to transmit encryption keys and gather user information to evade detection.

Some of the protections everyone, not just companies, but individual computer owners as well should implement are listed below. Though we naturally quantify the value of a company’s resources as greater than an individual, how can you truly calculate the significance of such items as family pictures and videos stored on personal computers?
