Retarus observes a major rise in crypto trojans
One in six emails contains a virus
As crypto trojans can morph their structure quickly and frequently and, as a result, are able to assume the most diverse forms at lightning speed, ransomware is not detected immediately by every virus scanner. Nevertheless, security can be increased using professional cloud services. Specialized email security services access several scanners in parallel, thereby continuously expanding their filter rules, which means they can always offer the latest protection levels. Additional mechanisms, such as a four-level virus scan, also increase the likelihood of identifying and blocking extortion trojans in good time.
Heightened vigilance is essential
To ensure the best possible protection from attacks by Locky and similar ransomware, email users must be highly vigilant. Retarus recommends that users deactivate the automatic execution of embedded macro code in Office programs and that macros should only be activated if they are absolutely essential and where the corresponding documents originate from known sources. In principle, users should only open email attachments if the sender or the process described in the email is trustworthy. So that potentially affected data can be restored quickly and – wherever possible – without losses, important data should be backed up on a regular basis. Here it should be noted that Locky can also attack external data media if this is permanently connected to the computer. Caution is also advised in the event of an extremely slow processor response, elevated hard drive activity without a detectable reason, or files with the extension .locky on the hard drive. To close existing gaps in security, the latest versions of virus scanners should always be installed and regular patches performed.
