Active since 2020, Conti Ransomware is yet another ransomware that operates in the double-extortion business model, publishing stolen data in their wall-of-shame if the ransom is not paid.
<div><br>
</div>
<div>For the encryption process, it uses a variation of ChaCha and AES-256, instead of the common RSA + AES combination. Conti is developed by the Wizard Spider group, the same developers of Trickbot (covered in our Daily Diary #84), that also deploys another
ransomware threat, Ryuk. In the beginning, it was believed that Conti was supposed to be an evolution of Ryuk, and would take its place, but even after a year, both malware pieces remain being used.</div>
<div><br>
</div>
<div>Today, September 22th, CISA, FBI, and NSA released a join advisory against Conti Ransomware. According to the advisory, Conti attacks are increasing, and companies should take the required measures to avoid being targeted. They also recommend keeping systems
up-to-date, requiring multi-factor authentication and implementing network segmentation.</div>
<div><br>
</div>
Our team got access to "ContiNews" website, their wall-of-shame. Only today three new targets were published, totaling 29 only in September. It's important to reinforce that data is published when a company decides not to pay the ransom, so the target list
might be larger. This website is now monitored by our team ransom-tracker, so we are constantly alerted in case a new target shows up.
