Russia convicted four REvil ransomware group members for distributing malware and illegal payment activities. The sentences ranged from 4.5 to 6 years as part of a broader crackdown following the 2021 Kaseya attack affecting over 1,500 global businesses. U.S. President Joe Biden's dialogue with Russian President Putin in 2021 pressured Russia to act against cybercriminals within its borders. Post-Kaseya attack, operations resumed briefly by REvil until their servers, unknowingly compromised by law enforcement, were used against them. In January 2022, the FSB disrupted the REvil operation, arresting 14 members and seizing assets worth $6.6 million after US-led international cooperation. The remaining REvil members face separate trials, continuing the legal response to one of the most high-profile ransomware cases.

Russian APT group APT29, linked to the SVR, targeted government and military entities using fake AWS domains to steal Windows credentials via malicious Remote Desktop Protocol (RDP) files. Amazon seized domains impersonating AWS in order to disrupt the operations of APT29, clarifying that their platform and customer credentials were not the actual targets. The campaign significantly impacted Ukraine but also targeted other countries considered adversaries by Russia, employing a wider than usual range of phishing targets. Phishing emails discussed 'integration' issues between Amazon and Microsoft, and promoted implementing a 'zero trust' security architecture, leading recipients to malicious RDP connection files. When the RDP files were opened, they connected to attacker-controlled servers, sharing all local resources including hard drives and network shares, potentially leading to unauthorized program executions. Ukraine’s CERT-UA issued warnings about the Rogue RDP attachments and recommended scrutinizing network interaction logs for signs of attacks or breaches. APT29 was recently revealed to have exploited software vulnerabilities in products from companies like TeamViewer and Microsoft among others, indicating a significant threat capability and broad operational scope.

Amazon Web Services (AWS) has resolved a vulnerability in its Cloud Development Kit (CDK), which could have allowed total account takeovers under certain conditions. The vulnerability was identified by Aqua Security researchers in the CDK’s mechanism of deploying resources, potentially enabling attackers to usurp control by namesquatting predictable S3 bucket names. AWS patched the issue on July 12, 2024, with the release of CDK version v2.149.0, following the discovery of the flaw on June 27 by Aqua researchers. Approximately one percent of AWS CDK users were exposed to this vulnerability, which AWS has now mitigated by updating how assets are deployed and verified. Affected users were directly notified by AWS to upgrade their CDK and bootstrap resources to secure their accounts against potential exploitation. The security flaw is partly a continuation of the "Bucket Monopoly" problem, where attackers could pre-load malicious code into predictable S3 bucket names and execute attacks unknowingly initiated by the target organization. AWS has implemented additional security controls in the CDK CLI to alert users about the need for an upgrade, reinforcing security against similar future vulnerabilities.
