The man behind a massive leak of U.S. government secrets that has exposed spying on allies, revealed the grim prospects for Ukraine’s war with Russia and ignited diplomatic fires for the White House is a young, charismatic gun enthusiast who shared highly classified documents with a group of far-flung acquaintances searching for companionship amid the isolation of the pandemic.

in February 2023, Kaspersky technologies detected a number of attempts to execute similar elevation-of-privilege exploits on Microsoft Windows servers belonging to small and medium-sized businesses in the Middle East, in North America, and previously in Asia regions. These exploits were very similar to already known Common Log File System (CLFS) driver exploits that we analyzed previously, but we decided to double check and it was worth it – one of the exploits turned out to be a zero-day, supporting different versions and builds of Windows, including Windows 11. The exploit was highly obfuscated with more than 80% of the its code being “junk” elegantly compiled into the binary, but we quickly fully reverse-engineered it and reported our findings to Microsoft. Microsoft assigned CVE-2023-28252 to the Common Log File System elevation-of-privilege vulnerability, and a patch was released on April 11, 2023, as part of April Patch Tuesday.

Microsoft addresses 97 CVEs, including one that was exploited in the wild as a zero day

Check Point Research recently discovered three vulnerabilities in the “Microsoft Message Queuing” service, commonly known as MSMQ. These vulnerabilities were disclosed to Microsoft and patched in the April Patch Tuesday update. The most severe of these, dubbed QueueJumper by CPR (CVE-2023-21554), is a critical vulnerability that could allow unauthorized attackers to remotely execute arbitrary code in the context of the Windows service process mqsvc.exe.

Microsoft analyzes a threat group tracked as DEV-0196, the actor’s iOS malware “KingsPawn”, and their link to an Israel-based private sector offensive actor (PSOA) known as QuaDream, which reportedly sells a suite of exploits, malware, and infrastructure called REIGN, that’s designed to exfiltrate data from mobile devices.

At least five civil society victims of QuaDream’s spyware and exploits were identified in North America, Central Asia, Southeast Asia, Europe, and the Middle East. Victims include journalists, political opposition figures, and an NGO worker. Traces of a suspected iOS 14 zero-click exploit used to deploy QuaDream’s spyware.

Researchers found malware developed by QuaDream, a little-known government spyware maker, which was used against journalists and politicians.

Several water monitors – which monitor irrigation systems and wastewater treatment systems – were left dysfunctional on Sunday after a cyber attack targeted the monitoring systems.

Specifically, water controllers for irrigating fields in the Jordan Valley were damaged, as were control systems for the Galil Sewage Corporation.

In recent days, the US Justice Department and Pentagon have begun investigating an apparent online leak of sensitive documents, including some that were marked “Top Secret”.

A portion of the documents, which have since been widely covered by the news media, focused on Russia’s invasion of Ukraine, while others detailed analysis of potential UK policies on the South China Sea and the activities of a Houthi figure in Yemen.

The existence of the documents was first reported by the New York Times after a number of Russian Telegram channels shared five photographed files relating to the invasion of Ukraine on April 5 – at least one of which has since been found by Bellingcat to be crudely edited.
