We analyze Cryptobot, aka Paycrypt

by

Recently during some research on encrypting ransomware we came across a new variant that brings some new features to the table. It will encrypt by utilizing the following javascript from being opened as an attachment from email (posing as some document file).   Once full encrypted you’ll get a popup text document informing you that all your files have been encrypted and how to pay money to get your key to decrypt. This specific sample is Russian, and the instructions were also in Russian so I didn’t show it here. The really interesting thing about this variant that I wanted to share […]

New Rogue “Antivirus System” locks you out of safe mode

by

By Tyler Moffitt Recently we’ve seen a new fake security product running around that has made improvements to the standard rogue. Typical rogues are annoying, but relatively easy to take care of. Previously, all you had to do was boot into safe mode with networking and remove the files and registry entries (or install Webroot). Support forums everywhere use safe mode with networking as the “go to” mode for virus removal as non-core components are not loaded at start up and it’s easier to isolate problems.

Novel Approach to Malware Discovery in today’s Threat Landscape

This is because those who spend their time and effort fighting such infections are likely to miss a mutation and therefor lack the chance to create a cure. This point is especially true with traditional antivirus technology where discovery and detection techniques have not kept up with the rapid pace of mutations common in today’s threat landscape. The recent NY […]
