One of the techniques used is a user-mode hooks bypass that enabled the malware to evade identification by various AV solutions for an extended period of time. It appears that the author behind this malware invested significant time and effort into remaining undetected by leveraging multiple evasion techniques. For example, in one of these encounters our research team was able to determine that the operator detected our activity and immediately responded to our activity by infecting the test machine with a customized piece of ransomware. The controlled infection is performed in order to investigate several aspects of the malware, as well as the reactivity of the malware operator. When the operator detects any interesting activity by one of the malware, they then proceed to install a custom remote access tool on the machine for manual operations.Īs part of our normal research activities, we occasionally perform a controlled infection of what seems to be a legitimate user endpoint. DarkGate has several capabilities, including crypto mining, stealing credentials from crypto wallets (crypto stealing), ransomware, and remote access and control.ĮnSilo observed that the author behind this malware established a reactive Command and Control infrastructure that is staffed by human operators who act upon receiving notifications of new infections with crypto wallets. Named DarkGate by the author, the malware seeks to infect targets across Europe, particularly in Spain and France. The technical analysis of the DarkGate malware that follows demonstrates how advanced malware can avoid detection by traditional AV products and highlights the importance of the post-infection protection capabilities of the enSilo Endpoint Security Platform. Is capable of detonating multiple payloads with capabilities that include cryptocurrency mining, crypto stealing (theft of credentials associated with crypto wallets), ransomware, and remote control.Uses two distinct User Account Control (UAC) bypass techniques to escalate privileges.Has the ability to evade the elimination of critical files by several known recovery tools.Uses multiple methods for avoiding detection by traditional AV using vendor-specific checks and actions, including the use of the process hollowing technique.Leverages a C&C infrastructure cloaked in legitimate DNS records from legitimate services, including Akamai CDN and AWS, which helps it avoid reputation-based detection techniques.The critical elements of the DarkGate malware are that it: When executed by the user, DarkGate malware is capable of avoiding detection by several AV products, and of executing multiple payloads including cryptocurrency mining, crypto stealing, ransomware, and the ability to remotely take control of the endpoint. Targeting Windows workstations and supported by a reactive Command and Control system, DarkGate malware is spread through torrent files. Recently, enSilo researcher Adi Zeligson - now part of the FortiGuard Labs research team - discovered a never-before-detected, highly sophisticated malware campaign named DarkGate. Flushing your DNS will wipe your saved IP addresses and force your system to lookup the IP address for Photobucket again.Threat Analysis: This blog originally appeared on the enSilo website and is republished here for threat research purposes. enSilo was acquired by Fortinet in October 2019. It's possible that the DNS has been modified or the IP address has changed. The Domain Name System is responsible for converting your URLs to the appropriate IP address. If you are still experiencing the issue, please try. It seems lately it has been getting worse. I think Photobucket has way to many thing going on in their web pages. I have been viewing Photobucket pages after clearing the DNS cache for the last 4 days and I have not had my browsers redirect to a scam.Īfter trying just about everything you where the only one that said to try flushing/clearing the DNS cache. It it appears that by flushing/clearing the DNS cache fixed this Photobucket redirect tech scam problem. Flushing your DNS will wipe your saved IP addresses and force your system to lookup the IP address for Photobucket again. If you are still experiencing the issue, please try flushing your DNS. Perhaps one of them is causing the issue. Check what programs you have installed on your computer, via the Windows control panel.
