Darth Vidar: The Dark Side of Evolving Threat Infrastructure
Darth Vidar: The Dark Side of Evolving Threat Infrastructure
Summary Three key takeaways from our analysis of Vidar infrastructure: Russian VPN gateways are potentially providing anonymity for Vidar operators / customers, making it more challenging for analysts to have a complete overview of this threat. These gateways now appear to be migrating to Tor. Vidar operators appear to be expanding their infrastructure, so analysts need to keep them in their sights. We expect a new wave of customers and as a result, an increase of campaigns in the upcoming weeks

Ransomware Diaries: Volume 1
Ransomware Diaries: Volume 1
The LockBit ransomware gang is one of the most notorious organized cybercrime syndicates that exists today. The gang is behind attacks targeting private-sector corporations and other high-profile industries worldwide. News and media outlets have documented many LockBit attacks, while security vendors offer technical assessments explaining how each occurred. Although these provide insight into the attacks, I wanted to know more about the human side of the operation to learn about the insights, motivations, and behaviors of the individuals on the other side of the keyboard. To prepare for this project, I spent months developing several online personas and established their credibility over time to gain access to the gang’s operation.

Assessing Potential Exploitation of Sophos Firewall and CVE-2022-3236
Assessing Potential Exploitation of Sophos Firewall and CVE-2022-3236
Sophos took immediate steps to remediate CVE-2022-3236 – an unauthenticated and remote code execution vulnerability affecting the Sophos Firewall Webadmin and User Portal HTTP interfaces – with an automated hotfix sent out in September 2022. Through its advisory published on September 23, 2022, it also alerted users who don't receive automatic hotfixes to apply the update themselves. The advisory stated the vulnerability had previously been used against "a small set of specific organizations, primarily in the South Asia region." In December, Sophos released v19.5 GA GA with an official fix. Key Takeaways * As there are no public proof-of-concept exploits for CVE-2022-3236, we created our own to determine its potential for mass exploitation. * We scanned internet-facing Sophos Firewalls and found more than 4,000 firewalls that were too old to receive a hotfix. * We encourage Sophos Firewall administrators to look through their logs to determine if they see indications of exploit attempts. Two files to focus on include /logs/csc.log and /log/validationError.log. * Internet-facing firewalls appear to largely be eligible for hotfixes and the default authentication captcha likely prevented mass exploitation.
