While ransomware attacks are not new, in recent months they have re-surfaced as an increasingly dangerous threat to businesses, home users and government agencies. Fortinet’s March Threatscape report is classifying the DigiPog ransomware Trojan as a top 10 malware threat for the month of March and is warning of an increasing attack volume.
Traditionally ransomware attacks work by holding a user’s computer hostage until some set of terms is met (pay fee, supply info, supply data).
The newest DigiPog ransomware strain is an SMS-based attack that requires victims to send an SMS message to a premium number in order to obtain a code to unlock their computer system.
A growing concern is that these types of attacks will be used to obtain sensitive data, rather than money – a significant cybersecurity threat to government agencies and businesses alike.
As is the case with most malware threats, prevention is far easier than removal. Whether you are a single user or a network administrator securing hundreds of computers, the logic is the same: protect all entry-points.
From a network perspective, this means ensuring you have a firewall with anti-virus and anti-spyware technology in place.
From a user perspective, this means warning your users against opening any email messages, and particularly email attachments, from unknown or dangerous looking sources.
From an email perspective, ensure you have an email protection solution in place that is able to adequately address these types of malware.
