This week we saw a few large scale attacks and various ransomware reports indicating ransom payments are falling, while attacks are increasingly destroying data permanently. The good news is a new ransomware decryptor was released, allowing victims to recover files for free.
As trust in a ransomware operation’s promise to delete stolen data is eroding, Coveware is seeing a decline in ransom payments as companies recover their files from backup.
Unfortunately, Coveware has also seen an increasing trend of ransomware attacks mistakenly causing permanent data destruction as they encrypt data. It unknown if this is caused by buggy software or sloppy and inexperienced attackers.
Some of the attack seen this week includes one against UK Research and Innovation (UKRI) and attacks on Brazilian electric utility companies Centrais Eletricas Brasileiras (Eletrobras) and Companhia Paranaense de Energia (Copel).
For some good news, a Fonix ransomware decryptor was released this week by Kaspersky that allows victims to recover their files for free. Fonix ransomware shut down its operation last Friday and released the master private decryption key.

UK Research and Innovation (UKRI) suffers ransomware attack
The UK Research and Innovation (UKRI) is dealing with a ransomware incident that encrypted data and impacted two of its services, one offering information to subscribers and the platform for peer review of various parts of the agency.

The Coveware Quarterly Ransomware Report describes ransomware incident response trends during Q4 of 2020. Ransomware groups continue to leverage data exfiltration as a tactic. However, the trust that stolen data will be deleted is eroding; defaults are becoming more frequent when exfiltrated data is made public despite the victim paying. As a result, fewer companies are giving in to cyber extortion when they are able to recover from back ups. This inflection led to a large decline in average ransom amounts paid. Stemming the tide of cyber extortion will only happen if the industry is starved of its profitability. This trend was a distinct positive during Q4.

Babyk Ransomware won’t hit charities, unless they support LGBT, BLM
The Babyk ransomware operation has launched a new data leak site used to publish victim’s stolen data as part of a double extortion strategy. Included is a list of targets they wont attack with some exclusions that definitely stand out.
Netgain ransomware incident impacts local governments
The ransomware incident that Netgain, a provider of managed IT services, had late last year rippled onto its customers. Now, Ramsey County, Minnesota, is informing clients of the Family Health Division program that the hackers may have accessed personal data.
In September 2020, Cisco Talos established contact with a self-described LockBit operator and experienced threat actor. Over the course of several weeks, we conducted multiple interviews that gave us a rare, first-hand account of a ransomware operator’s cybercriminal activities. Through these exchanges, we gleaned several valuable takeaways for executives and the broader cybersecurity community.
Michael Gillespie found new STOP Djvu ransomware variants that append the .plam and .cosd extensions to encrypted files.
MalwareHunterTeam found a new VashSorena variant that appends the .lucifer extension and drops ransom notes named HELP_DECRYPT_YOUR_FILES.txt and HELP_DECRYPT_YOUR_FILES.html.
MalwareHunterTeam found a new Nefilim ransomware variant that appends the .DERZKO and drops a ransom note named DERZKO-HELP.txt.
MalwareHunterTeam found another Nefilim ransomware variant that appends the .MILIHPEN and drops a ransom note named MILIHPEN-INSTRUCT.txt.

New Fonix ransomware decryptor can recover victim’s files for free
Kaspersky has released a decryptor for the Fonix Ransomware (XONIF) that allows victims to recover their encrypted files for free.
Ransomware continues the trend of targeted attacks but with the added challenge of double extortion. Organizations need to be one step ahead of such coercive tactics to avoid potential disruptions, financial losses, and reputational damage.
Trucking and freight transportation logistics company Forward Air said a recent ransomware attack left a dent of $7.5 million in its Q4 financial results.

Ransomware attacks increasingly destroy victims’ data by mistake
More and more ransomware victims are resisting the extortionists and refuse to pay when they can recover from backups, despite hackers’ threats to leak the data stolen before encryption.
As we’ve covered on our blog, there may be fewer cybercriminals responsible for ransomware attacks than one would initially think given the number of individual attacks, distinct strains, and amount stolen from victims. Cybersecurity researchers point out that many RaaS affiliates carrying out attacks switch between different strains, and many believe that seemingly distinct strains are actually controlled by the same people. Using blockchain analysis, we’ll investigate potential connections between four of 2020’s most prominent ransomware strains: Maze, Egregor, SunCrypt, and Doppelpaymer.
xiaopao found a HDLocker ransomware that appends the _HD string to encrypted file’s names.
xiaopao found a Xorist ransomware variant that appends the .omfl extension to encrypted file’s names.
