Ransomware is a threat to all organizations and has been prevalent for a number of years. Although recent reports suggest that organizations are no longer as scared of it as they once were, it is still something that genuinely threatens to cause downtime and cause havoc on a daily basis especially given the ease at which an infection can occur.

2017 saw attacks on a mass scale affecting thousands of organisations at once, 2018 has had its own share of attacks but on a smaller scale. The latest attacks have, in their own way, caused huge amounts of damage even if temporary or less headline-grabbing.

Town ditches digital to cope with Ransomware attack

In late July, a government department in Alaska was infected with a malware strain, which according to reports may have been sitting dormant for several months. The infection was able to take over more than 500 machines and bring the organizations to its knees for a time. Systems infected included the organizations email server, internal systems, and disaster recovery server, damaging backup data.

The short-term solution for the organization was to revert to manual systems, dusting off typewriters and resorting to writing receipts by hand. While backup data stored on the server had been damaged some data was recoverable. IT Director for the organization, Eric Wyatt stated:

                “There is optimism for the recovery of more data”

Ransomware is an ongoing threat and one that has proven profitable for cyber-criminal’s savvy enough to pull it off. One particular strain SamSam has reportedly extorted almost $6 million since January 2016.

 

SamSam turns a profit for cyber-crooks

There are some well-known strains of malware and ransomware such as WannaCry and Petya, but a lesser-known strain named SamSam has been actively targeting organizations for several years, making a tidy profit for the cyber-criminals behind it. Security firm Sophos has recently revealed research to show that the strain has successfully extorted some $5.9 million from organizations since 2016. Of the victims who paid up around 74% of organizations were US-based, with other victims coming from the UK, Canada, and Belgium; these organizations reportedly include schools and hospitals.

Sophos commenting on the strain:

“Unlike most other ransomware, SamSam encrypts not only document files, images and other personal or work data, but also configuration and data files required to run applications”

Another difference with the SamSam strain is that it is a manually triggered attack, rather than being triggered by a phishing scam (email) or compromised download.

“The entire attack process is manual. No badly worded spam email with an attachment is the culprit. The attacker breaks-in in the old-fashioned way: using tools that attempt as many logins as quickly as the Remote Desktop Protocol will permit, and exploits operating system vulnerabilities, though not as many as you'd think. SamSam usually succeeds when the victim chooses a weak, easily guessed password”

 

Organisations fighting back against Ransomware

Ransomware and malware are a well-known threat to organizations and a threat that is increasingly being prepared for and protected against. Recently a Taiwanese company that manufactures chips for Apple iPhone’s was able to recover from an attack following a mistake upon implementation of a new tool which allowed an infection in. Organisations are increasingly able to recover against the effects of ransomware and due to increase knowledge and staff training, infections are less likely to occur. Following best practice, many organizations are preparing for attacks by ensuring that all systems are recoverable and that an off-site backup is in place.
