Full Article:

Microsoft recently published a report on foreign influence operations targeting the 2024 US elections. The report highlighted efforts by Russia to undermine U.S. support for Ukraine and China to exploit societal polarization. Microsoft found that generative AI is being used by Russia, China, and Iran to support their influence campaigns. Separately, CISA, FBI, and ODNI issued an advisory on election interference by China, Russia, and Iran.

Palo Alto Networks disclosed a critical zero-day vulnerability in its GlobalProtect VPN product. The vulnerability allows attackers to execute arbitrary code with root privileges. Volexity researchers identified a threat actor exploiting the flaw and creating a reverse shell on affected devices.

RansomHub has begun leaking data allegedly stolen during the Change Healthcare attack, where the ALPHV/Blackcat ransomware gang demanded a $22 million ransom. UnitedHealth Group revealed that the attack has cost the company $872 million so far, with expected costs to exceed $1 billion by year-end.

Mandiant tied OT attacks to Russia’s GRU, specifically the Sandworm group, now tracked as “APT44.” This group has been attributed to various global cyber operations, and has collaborated with hacktivist groups in attacks against OT systems. Ukraine-linked hackers also deployed ICS malware against a Russian infrastructure company, causing damage to remote sensors and IoT devices.

Lastly, a cyberattack hit the New York State Legislature office, disrupting activities related to enacting the state budget. Cisco Talos warned of a surge in brute-force attacks against VPN services, web application authentication interfaces, and SSH portals originating from TOR exit nodes and other anonymizing tunnels.
