Disturbing Trend: More and More Ransomware Attack Victims Are Paying Ransom
UK's largest police forensics lab Eurofins reportedly paid ransom to ransomware attackers. The company joins the growing list of organizations that paid ransom to ransomware attackers.
The BBCrecently reported that Eurofins, UK's largest police forensics lab, paid an undisclosed amount to attackers after its computers were crippled by a ransomware attack. Eurofins Scientific, which has about 45,000 staff in more than 800 laboratories across 47 countries, is one of the global independent market leaders in testing and laboratory services for forensics. Eurofins Forensics Services, Eurofins Scientific's Forensics subsidiary which is based in the UK, is one of the primary forensic services providers to the UK police.
Last June 3, Eurofins Scientificdisclosed that during the first weekend of June 2019 (1stand 2ndJune) it fell victim to ransomware attack which caused disruption to many of its IT systems in several countries. The company said, in a statement, that from June 4th, it was able to “resume full or partial operations for a number of impacted companies and continue to do so every day”. As of June 17th, the company said, the vast majority of affected laboratories’ operations had been restored.
The ransomware involved, Eurofins Scientific said, appears to be a new ransomware variant which was “initially non-detectable by the anti-malware screen of our leading global IT security services provider at the time of the attack and required an updated version made available only hours into the attack”.
In a ransomware attack, a malicious actor or actors lock out legitimate users of IT systems or computer files through encryption (the process of converting plain texts to codes so that only people with access to a secret key, also known as decryption key, can access it). Ransomware attackers demand from their victims to pay ransom in exchange for the decryption keys that would unlock the encrypted IT systems or computer files.
Growing List of Ransomware Victims Paying Ransom
Eurofins Scientific joins the growing list of ransomware victims paying ransom. Two cities in Florida, U.S. and 2 towns in Ontario, Canada publicly admitted that they paid ransom to ransomware attackers.
Last June 17th, the City Council of the City of Riviera Beach, Florida unanimously approved the payment of ransom to ransomware attackers. A total of 65 bitcoins was paid to the ransomware attackers, equivalent to approximately $600,000 at the time of the ransom payment approval.
A few days after the ransom payment approval of the City Council of Riviera Beach City, another city in the Florida state Lake City paid its own ransomware attackers ransom. Lake City Mayor Stephen Witt told a local mediathat Lake City will pay cyber attackers USD $460,000 to get its computer system back. “I would’ve never dreamed this could’ve happened, especially in a small town like this,” the Lake City Mayor said.
Two towns in Ontario, Canada, the Town of Wasaga Beach and Town of Midland, have also publicly admitted that they paid ransom to ransomware attackers. Jocelyn Lee, Director of Finance and Treasurer of the Town of Wasaga Beach, reported to the City Council of Wasaga Beach that on April 30, 2018 the Town’s computer system was infected with a malicious software (malware) that left all of the Town’s data locked. Lee said the Town ended up paying the ransomware attackers 3 bitcoins, equivalent to $34,950 Canadian at the time of the ransom payment.
The Town of Midland, Ontario, meanwhile, in a statement said that on September 1, 2018, the Town's network was infected with ransomware. The Town said that it paid an undisclosed amount to the ransomware attackers in exchange for the decryption keys. In paying the ransom, the Town of Midland said, “Although not ideal, it is in our best interest to bring the system back online as quickly as possible.”
To date, South Korean web hosting company Nayanaholds the record of paying the most expensive ransom, totaling 397.6 bitcoins, valued USD$1.01 million at the time of the ransom payment.
Prevention & How to Recover from Ransomware Attacks
All ransomware victims that decided to pay ransom have one thing in common: They all failed to conduct regular back-up of their critical data. Organizations that diligently conduct regular back-up of critical data, in time of crisis, such as ransomware attack, can simply ignore the attackers’ ransom demand.
Paying the ransom also doesn’t guarantee that attackers will hand over the correct decryption keys that will unlock encrypted IT systems or computer files. Paying the ransom could instead encourage the attackers to launch another ransomware attack or the attackers could increase their ransom payment demand, knowing that organizations will likely consider paying the amount.
While conducting regular back-up of critical data is important, implementing cybersecurity measures that prevent ransomware attacks are equally important as well. The UK's National Cyber Security Centre (NCSC)recently issued a Ryuk Ransomware Advisory. Ryuk is a particular type of ransomware that was first observed in the wild in August 2018. It has since been responsible for multiple attacks worldwide. This ransomware, in particular, targets its victims and ransom payment is set based on the target’s perceived ability to pay.
NCSC recommends the following measures in order to prevent ransomware attacks, in particular, Ryuk ransomware attacks:
