Improper authentication in Windows SMB Server allows an authorized attacker to perform tampering over a network.

**How could an attacker exploit this vulnerability?** To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system. Additionally, an attacker could convince a local user to open a malicious file. The attacker would have to convince the user to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file.

Improper validation of specified type of input in Windows Local Session Manager (LSM) allows an authorized attacker to deny service over a network.

**What type of information could be disclosed by this vulnerability?** An attacker who successfully exploited this vulnerability could obtain Single Sign-On (SSO) cookies in ADFS logs.

Insertion of sensitive information into log file in Windows Failover Cluster allows an authorized attacker to disclose information locally.

Exposure of sensitive information to an unauthorized actor in Windows NTLM allows an unauthorized attacker to perform spoofing locally.

Heap-based buffer overflow in Windows DWM Core Library allows an authorized attacker to elevate privileges locally.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

Cybersecurity researchers have shed light on a previously undocumented threat actor called TA585 that has been observed delivering an off-the-shelf malware called MonsterV2 via phishing campaigns. The Proofpoint Threat Research Team described the threat activity cluster as sophisticated, leveraging web injections and filtering checks as part of its attack chains. "TA585 is notable because it

Every week, the cyber world reminds us that silence doesn’t mean safety. Attacks often begin quietly — one unpatched flaw, one overlooked credential, one backup left unencrypted. By the time alarms sound, the damage is done. This week’s edition looks at how attackers are changing the game — linking different flaws, working together across borders, and even turning trusted tools into weapons.
