Ransomware is not new, but its exponential growth curve has made it a pervasive threat to end users.
This extortion-based category of cybercrime uses encryption to block access to select files on a compromised endpoint. In most cases, the only way to retrieve the encrypted files is to restore from a pre-existing backup, or pay a ransom which can vary from a few hundred up to a few thousand dollars, depending on the victims’ size and ability to pay. Ransomware prevention represents a significant security challenge because the technology evolves constantly, as cyber criminals refine their tools, techniques, and procedures.
According to an article on CNN, ransomware cost businesses and organizations about $209 million in the first quarter of 2016, which was on track to grow to $1 billion by the end of the year. Ransomware attacks saw a 300% increase since 2015. One type of ransomware that is becomingly increasingly popular is fileless ransomware that infects administrative tools. CrowdStrike has created an infographic about ransomware to help businesses understand how they can get infected and what to look out for.
