BleepingComputer reports that the Quantum ransomware was able to complete an attack from initial infection to complete device encryption within a span of three hours and 44 minutes, making it one of the quickest ransomware attacks.
Security researchers at The DFIR Report discovered that Quantum ransomware achieved initial access through the IcedID malware distributed through a phishing email with an ISO file attachment. Attackers then move to bypass detection by deploying Cobalt Strike into a C:WindowsSysWOW64cmd.exe process two hours following initial infection before exfiltrating Windows domain credentials.
"For the next hour, the threat actor proceeded to make RDP connections to other servers in the environment. Once the threat actor had a handle on the layout of the domain, they prepared to deploy the ransomware by copying the ransomware (named ttsel.exe) to each host through the C$ share folder," said DFIR, which added that the Quantum ransomware payload was deployed through WMI and PsExec.
A new CRA study finds that a growing fear of ransomware attacks, and the need for data to effectively inform leadership, has driven many organizations to pursue access to more indepth threat intelligence.
Society at large is getting more vulnerable and less capable of safely navigating the complex cybersecurity landscape, said former CISA Director Chris Krebs at the Black Hat hacker conference in Las Vegas.
