I’m sure you have already heard about the global ransomware (WannaCrypt) attacks that occurred on Friday. Major news outlets like Bloomberg and CNN are calling this the largest ransomware attack to date. Our security analysts are warning us that this is just the beginning.
This type of attack, marries ransomware with worm type spread focused on PetrWrap, similar to WannaCrypt, which targets businesses based on it’s wormy spread. This type of attack is fairly unsophisticated, leveraging simple spam+binary and web exploit delivery methods.
In the case of WannaCrypt (actually WannaCryptOr 2.0), its success was due to exploiting vulnerabilities in Windows file sharing systems. These vulnerabilities had already been patched in supported operating systems. Due to the significant number of machines which were not fully patched or still running older versions of Windows, WannaCrypt was able to have a big impact.
This attack underlines the importance of regular, controlled patching which is what our AVG Managed Workplace platform allows us to manage for our customers. We urge you to make sure you are aware of the value of patching and regular backups. Many security analysts, including our own, have said with proper patching and backups in place the effects of this attack would have been significantly lessened.
For more information about patch and backups please give Fred or Rob a call at FGS to find out more.
