Critical Microsoft Outlook bug PoC shows how easy it is to exploit

Security researchers have shared technical details for exploiting a critical Microsoft Outlook vulnerability for Windows (CVE-2023-23397) that allows hackers to remotely steal hashed passwords by simply receiving an email. Microsoft yesterday released a patch for the security flaw but it has been exploited as a zero-day vulnerability in NTLM-relay attacks since at least mid-April 2022. The issue is a privilege escalation vulnerability with a 9.8 severity rating that affects all versions of Microsoft Outlook on Windows. An attacker can use it to steal NTLM credentials by simply sending the target a malicious email. No user interaction is needed as exploitation occurs when Outlook is open and the reminder is triggered on the system.

Cisco Talos researchers have reported that the Prometei botnet has infected more than 10,000 systems worldwide since November. The crypto-mining botnet has a modular structure and employs multiple techniques to infect systems and evade detection. The botnet was first observed by Cisco Talos experts on July 2020. A deep investigation on artifacts uploaded on VirusTotal allowed the experts to determine that the botnet may have been active at least since May 2016. Experts pointed out that the malware has constantly been updated by its creators with the implementation of new modules and features.

Chinese and Russian hackers using SILKLOADER malware to evade detection

Threat activity clusters affiliated with Chinese and Russian cybercriminal ecosystems have been observed using a new piece of malware that’s designed to load Cobalt Strike onto infected machines. Dubbed SILKLOADER by Finnish cybersecurity company WithSecure, the malware leverages DLL side-loading techniques to deliver commercial adversary simulation software. The development comes as improved detection capabilities against Cobalt Strike, a legitimate post-exploitation tool used for red team operations, is forcing threat actors to seek alternative options or concoct new ways to propagate the framework to evade detection.

Senators call on CISA to examine cybersecurity risks of Chinese consumer drones

A bipartisan group of senators is asking CISA to examine consumer drones made by a company with “deep ties” to the Chinese Communist Party, warning that they could be used to spy on U.S. critical infrastructure. Several companies are in the process of expanding the use of consumer drones across the U.S. for everything from food delivery to emergency services. But U.S. senators Mark Warner (D-VA) and Marsha Blackburn (R-TN) said CISA needs to step in and “reevaluate the risks associated” with drones built by Shenzhen DJI Innovation Technology – a company they accuse of having links to China’s government. A CISA spokesperson said it will not comment on the letter publicly and plans to respond directly to the senators.
