Ransomware made headlines again, starting with a campaign that hit companies in Spain, including Cadena Sociedad Española de Radiodifusión (SER), the country’s largest radio network. In another part of the globe, threat actors managed to infect government systems in the sparsely populated Canadian territory of Nunavut with ransomware.
Cadena SER released a statement on their webpage confirming the ransomware attack, noting that it had a significant and widespread impact on their systems. Although in-depth details regarding the attack were not provided, the message from the company said their technicians were working to recover the local programming of each of their stations, indicating that broadcasts — at least at the local level — were affected. The station also disconnected its computers from the internet as part of its security protocol.
According to reports from various media outlets, the Spanish IT consulting firm Everis was also a victim of ransomware. While the company has yet to release a public acknowledgement of the incident, leaks posted on social media show that the ransom note sent to the organization used the same text as the ones used in previous BitPaymer (detected as Ransom.Win32.BITPAYMER) attacks.
Even the remote Canadian region of Nunavut was not spared from ransomware. In a news release published on the Nunavut government’s website, the still-unknown ransomware variant used in the attack managed to encrypt individual files on various servers and workstations, resulting in disruption to government services that require access to electronic information stored on the network.
While these services are still open, the Nunavut government said that delays are to be anticipated. Furthermore, the government is also working on restoring data using existing back-ups.
Ransomware has been on the rise once again — according to Trend Micro’s 2019 midyear security roundup, ransomware detections in the first half of the year were up 77% compared to the latter half of 2018. Additionally, threat actors are expanding their scope of operations, not just targeting individuals and businesses but seeking new victims as well — notably local governments that lack comprehensive security systems in place.
It is highly recommended that organizations across all sectors implement the following best practices to prevent ransomware from affecting their systems:
