In the never-ending saga of Ransomware, the threat groups that deploy or leverage this tool for financial gain are always looking for a new method of installation and ways to avoid increasingly sophisticated security measures. Although most organizations might not be employing overly sophisticated security, the really good targets might be. Even the use of advanced MDR/XDR makes the exposure window smaller when it comes to many ransomware attacks.

As part of our ongoing (really never ending) series on modern ransomware, we are taking a look at a recent study of one Ransomware as a Service operation. In this case the look is at the Qilin scheme which was brought to light by Group-IB. They were able to infiltrate the group through a conversation with a recruiter (nothing like being invited in). The cybersecurity firm started their inside look in March of 2023 and what they found was eye opening. It shows that RaaS clearly pays well and that services like this make things easy and profitable for people looking to get in on the “fun” but might not have the skill set or infrastructure to do it on their own.

The same Ransomware gang that hit MSI recently also appears to have hit Pharmacy services provider PharMerica and stole information on 5.8 million patents. The data that was exfiltrated as part of the attack includes social security numbers, full name and address, health insurance, medications, and date of birth. PharMerica disclosed the breach to the Maine Attorney General on March 12th, 2023.

There is a new player in the ransomware space. Dubber RA group this new organization appears to have had their grand opening last month (April 2023). RA Group published a data leak site on the dark web as part of the now all too familiar double extortion scheme that most ransomware brings to the table. RA Group is also one of the organizations that has leveraged the Babuk source code links to get things going, as reported by Cisco Talos.

After a Leak of Babuk ransomware source code in late 2021 researchers have identified 9 separate new stains that are intended to target VMware ESXi. The new variants first started showing up in the 2cond half of 2022. As with ransomware as a service, having leaked source code allows less sophisticated attack groups to utilize the work of others to their advantage. In this case the targeting the Linux based ESXi. ESXi is a great target as it allows for the encryption of infrastructure and prevents the rapid restoration of systems since the infrastructure those servers run on is what has been affected.

Yesterday we reported on a ransomware attack that impacted PC and component manufacturer MSI. When they, MSI, disclosed the attack they claimed there was no significant impact, but failed to consider that most, if not all, modern ransomware attacks also incorporate exfiltration techniques to ensure a ransom is paid. This this case, the group Money Message had exfiltrated data a claimed 1.5TB of data that included firmware, source code, and databases. This sounds a bit significant at this point.

In January of 2023 the Print Management Software company PaperCut was advised of two Remote Code Execution (RCE) bugs. These bugs were in their PaperCut MF and PaperCut NG software products. PaperCut worked with the group that identified the bugs, TrendMicro, to develop a patch prior to disclosure of the flaw. The patch was made available to PaperCut clients on March 8th and the vulnerability was disclosed on April 20th. However, as is the case with things like this, the patches were not rolled out as one would have hoped.

Updated May-08-2023 with statement from Intel
Back in early April MSI, a popular PC and PC component maker, disclosed that it had a security incident. They stated that they quickly rolled out their Incident Response Team and enacted their recovery procedures (IR and BC/DR plans). Not much was known about the attack at the time, including when the incident happened, just that the disclosure was made to the relevant authorities.

Ransomware is a pain in the ass, no matter what type it is. You have a piece of code that comes in, encrypts all your files, steals them and then you must deal with paying a ransom of some sort to either get your files back or prevent potential disclosure of sensitive information. It is not exactly what you want to deal with on a given day. So, when a new method of deploying ransomware pops up you can excuse our thinking “oh what fresh hell is this”.

One of the things that has always confused me is how often a business will look at and spend on revenue generating and very little on revenue maintenance. Every budget year you see money thrown at expansion, new tools or software that bring in more money and I get it. You have to earn to keep the lights on. However, you also need to ensure that you can keep what you earn. Think about it like this, if you have a business and it only takes cash you would not just leave the cash laying around for anyone to take. No, you would invest in a secure place like a safe to keep it. This concept also involves modern “digital” businesses, but we just are not seeing them spend any money on the safe.
