Android Security Update: Google Addresses 120 Vulnerabilities, Including Two Actively Exploited Zero-Days

Sep 03, 2025
Mobile Security / Vulnerability

Google has released security updates for September 2025, patching 120 vulnerabilities in its Android operating system. Among these are two critical issues that have been confirmed as actively exploited in targeted attacks. The key vulnerabilities are:

  • CVE-2025-38352 (CVSS score: 7.4): A privilege escalation flaw in the Linux Kernel component.
  • CVE-2025-48543 (CVSS score: 7.4): A privilege escalation flaw in the Android Runtime component.

Both vulnerabilities allow for local privilege escalation without requiring additional execution privileges or user interaction. While Google has not detailed how these vulnerabilities are being exploited in the wild or if they are being leveraged together, they acknowledge signs of “limited, targeted exploitation.” Benoît Sevens from Google’s Threat Analysis Group (TAG) is credited with discovering and reporting these critical flaws.

New Microsoft Exchange ‘ProxyToken’ Vulnerability Allows Attackers to Alter Mailbox Configurations

Details have surfaced regarding a recently patched security flaw in Microsoft Exchange Server that could be exploited by unauthenticated attackers to change server settings, potentially exposing Personally Identifiable Information (PII). The vulnerability, identified as CVE-2021-33766 (CVSS score: 7.3) and referred to as “ProxyToken,” was found by Le Xuan Tuyen, a researcher at the Information Security Center of Vietnam Posts and Telecommunications Group (VNPT-ISC), and reported through the Zero-Day Initiative (ZDI) program in March 2021. According to the ZDI, “With this vulnerability, an unauthenticated attacker can perform configuration actions on mailboxes belonging to arbitrary users.” For instance, the attacker could redirect all emails sent to a targeted account to a mailbox they control. Microsoft addressed this issue in its Patch Tuesday updates for July 2021.

FBI Collaborated with Anonymous and LulzSec Hackers to Target Foreign Governments

August 28, 2013

Sentencing for former LulzSec leader Hector Xavier Monsegur, also known as “Sabu,” has been postponed again. Monsegur, who pleaded guilty to multiple criminal charges two years ago, faces a maximum sentence exceeding 124 years. Additionally, fellow LulzSec hacker Jeremy Hammond has alleged that the FBI utilized Sabu to orchestrate attacks against foreign governments, leveraging the efforts of Anonymous and other hackers.

The ongoing delays suggest that the FBI may not be fully extracting information from Monsegur, hinting at the possibility that he is assisting with other covert operations as claimed by Hammond. In a recent statement, Hammond accused the U.S. government of directing Monsegur to motivate fellow hacktivists to breach foreign government entities. “What many don’t realize is that Sabu was also used by his handlers to orchestrate hacking activities targeting government-selected entities, including multiple foreign government websites,” Hammond stated.

Preventing Data Leaks Before They Strike

In January 2025, cybersecurity experts from Wiz Research uncovered a significant data leak at Chinese AI firm DeepSeek, which compromised over 1 million sensitive log streams. The researchers discovered a publicly accessible ClickHouse database associated with DeepSeek, granting potential full control over database operations and allowing access to internal data. This incident included more than a million lines of log streams containing chat histories, secret keys, and more. Wiz promptly notified DeepSeek, which took immediate action to secure the vulnerability. However, this event highlights the persistent risk of data leakage. Whether intentional or accidental, data leakage encompasses various scenarios, as defined by IBM, which describes it as the unintentional exposure of sensitive information to unauthorized parties. On the intentional side…

Vulnerability in Linphone SIP Stack Could Allow Attackers to Remotely Crash Client Devices

On September 1, 2021, cybersecurity researchers revealed a zero-click vulnerability in the Linphone Session Initiation Protocol (SIP) stack. This flaw can be exploited remotely to crash the SIP client without any action needed from the victim, leading to a denial-of-service (DoS) condition. Identified as CVE-2021-33056 (with a CVSS score of 7.5), it arises from a NULL pointer dereference in the “belle-sip” component, a C-language library that supports SIP transport, transactions, and dialog layers. All versions prior to 4.5.20 are affected. The vulnerability was discovered and reported by the cybersecurity company Claroty. Linphone is an open-source, cross-platform SIP client that facilitates voice and video calls, end-to-end encrypted messaging, and audio conferences. SIP is the signaling protocol used to initiate, maintain, and terminate real-time multimedia communication sessions.

Zero-Day Exploit in Internet Explorer Used for Targeted Watering Hole Attacks on Japanese Users

Sep 24, 2013

Attackers are leveraging a zero-day vulnerability, CVE-2013-3893, in Microsoft’s Internet Explorer browser to target Japanese users through compromised popular news websites. According to FireEye, at least three major Japanese media outlets fell victim to these watering hole attacks, part of an operation dubbed “DeputyDog,” which appears to focus on manufacturers, government entities, and media organizations within Japan. The compromised sites experienced over 75,000 page views before the exploits were detected. This vulnerability in Internet Explorer versions 8 and 9 enables the covert installation of malware on users’ devices, granting hackers remote access. Typically, these attackers deploy Trojans tailored for targeted operations aimed at stealing intellectual property. Researchers identified a payload disguised as an image file hosted on a Hong Kong server that was used against a Japanese target. The attacks were uncovered just two days after Microsoft disclosed the vulnerability.
