Analysis reveals active attack server used by Maze affiliate

On 22 Jul 2020, security researcher analysis revealed that an active attack server had been used by a threat-actor affiliate of Maze ransomware operations. Reportedly the Maze affiliate gained initial access by using an infected system with remote desktop protocol opened to the Internet for scanning. They then looked for other systems and mapped out the network before using an unnamed loader to distribute the Maze ransomware. Observations indicated that the threat actor used the following tools: GMER, Mimikatz, Metasploit, Cobalt Strike, PowerShell, AdFind, Koadic, and PowerShell Empire.

Cyber-mercenary group Deceptikons uncovered

On 29 Jul 2020, security researchers reported on hacker-for-hire group “Deceptikons”, which has provided hacking services for almost a decade. The cyber-mercenary group’s targeting of commercial entities―specifically, targets not involved in government―is unusual for an APT group. Deceptikons was likely responsible for a spearphishing attack on multiple European law firms in 2019, deploying PowerShell scripts and using modified link files to compromise systems and execute a PowerShell backdoor. The group is not considered technically advanced, but the infrastructure and malware it uses focuses on gaining persistence on infected hosts.
