Microsoft Patches Entra ID Role Flaw That Enabled Service Principal Takeover

Microsoft Patches Entra ID Role Flaw That Enabled Service Principal Takeover

Apr 28, 2026 Vulnerability / Identity Management
An administrative role meant for artificial intelligence (AI) agents within Microsoft Entra ID could enable privilege escalation and identity takeover attacks, according to new findings from Silverfort . Agent ID Administrator is a privileged built-in role introduced by Microsoft as part of its agent identity platform to handle all aspects of an AI agent's identity lifecycle operations in a tenant. The platform enables AI agents to authenticate securely and access necessary resources, as well as discover other agents. However, the shortcoming discovered by the identity security platform meant that users assigned the Agent ID Administrator role could take over arbitrary service principals , including those beyond agent-related identities, by becoming an owner and then add their own credentials to authenticate as that principal. "That's full service principal takeover," security researcher Noa Ariel said . "In tenants where high-privileged service principals...
Microsoft Confirms Active Exploitation of Windows Shell CVE-2026-32202

Microsoft Confirms Active Exploitation of Windows Shell CVE-2026-32202

Apr 28, 2026 Vulnerability / Threat Intelligence
Microsoft on Monday revised its advisory for a now-patched, high-severity security flaw impacting Windows Shell to acknowledge that it has been actively exploited in the wild. The vulnerability in question is CVE-2026-32202 (CVSS score: 4.3), a spoofing vulnerability that could allow an attacker to access sensitive information. It was addressed as part of its Patch Tuesday update for this month. "Protection mechanism failure in Windows Shell allows an unauthorized attacker to perform spoofing over a network," Microsoft noted in an alert. "An attacker would have to send the victim a malicious file that the victim would have to execute." "An attacker who successfully exploited the vulnerability could view some sensitive information (Confidentiality) but not all resources within the impacted component may be divulged to the attacker. The attacker cannot make changes to disclosed information (Integrity) or limit access to the resource (Availability)."...

⚡ Weekly Recap: Fast16 Malware, XChat Launch, Federal Backdoor, AI Employee Tracking & More

Apr 27, 2026 Cybersecurity / Hacking
Everything is dumb again. This week feels broken in a very familiar way. Old tricks are back. New tools are doing shady crap. Supply chains got hit. Fake help desks worked. Weird research showed how easy some attacks still are. Most of it feels like stuff we should have fixed years ago. Bad extensions. Stolen creds. Remote tools are getting abused. Malware hides in places people trust. Same mess, cleaner packaging. Coffee is cold. The vuln list is ugly. Let’s get into it. ⚡ Threat of the Week New fast16 Malware Was Developed Years Before Stuxnet —A new Lua-based malware called fast16, created years before the notorious Stuxnet worm, is designed to primarily target high-precision calculation software to tamper with results. The framework dates back to 2005. Analysis suggests that fast16 was active at least five years before the emergence of Stuxnet. Widely regarded as a joint U.S.-Israeli project, Stuxnet marked a turning point in cyber warfare as the first disruptive digital weap...

PhantomCore Exploits TrueConf Vulnerabilities to Breach Russian Networks

PhantomCore Exploits TrueConf Vulnerabilities to Breach Russian Networks

Apr 27, 2026 Vulnerability / Hacktivism
A pro-Ukrainian hacktivist group called PhantomCore has been attributed to attacks actively targeting servers running TrueConf video conferencing software in Russia since September 2025. That's according to a report published by Positive Technologies, which found the threat actors to be leveraging an exploit chain comprising three vulnerabilities to execute commands remotely on susceptible servers.     "Despite the fact that there are no exploits for this chain of vulnerability in public access, attackers from PhantomCore managed to conduct their research and reproduce vulnerabilities, which led to a large number of cases of its operation in Russian organizations," researchers Daniil Grigoryan and Georgy Khandozhko said . PhantomCore , also called Fairy Trickster, Head Mare, Rainbow Hyena, and UNG0901, is the name assigned to a politically- and financially-motivated hacking crew that has been active since 2022 following the Russo-Ukrainian war.

Researchers Uncover Pre-Stuxnet ‘fast16’ Malware Targeting Engineering Software

Researchers Uncover Pre-Stuxnet ‘fast16’ Malware Targeting Engineering Software

Apr 25, 2026 Cyberwarfare / National Security
Cybersecurity researchers have discovered a new Lua-based malware created years before the notorious Stuxnet worm that aimed to sabotage Iran's nuclear program by destroying uranium enrichment centrifuges. According to a new report published by SentinelOne, the previously undocumented cyber sabotage framework dates back to 2005, primarily targeting high-precision calculation software to tamper with results. It has been codenamed fast16 . "By combining this payload with self-propagation mechanisms, the attackers aim to produce equivalent inaccurate calculations across an entire facility," researchers Vitaly Kamluk and Juan Andrés Guerrero-Saade said in an exhaustive report published this week. Fast16 is estimated to predate Stuxnet – the world's first known digital weapon designed for disruptive actions – by at least five years. While Stuxnet is widely attributed to the U.S. and Israel and later served as the architectural foundation for the Duqu information-...
