Google Issues Android Security Patch to Address 3 Actively Exploited Vulnerabilities

Date: July 7, 2023

In its latest security update, Google has addressed 46 new vulnerabilities in the Android operating system, highlighting three that are actively exploited in targeted attacks. Notably, CVE-2023-26083 pertains to a memory leak issue in the Arm Mali GPU driver for Bifrost, Avalon, and Valhall architectures. This vulnerability was previously exploited in December 2022, allowing spyware to infiltrate Samsung devices. Its severity prompted the Cybersecurity and Infrastructure Security Agency (CISA) to issue a patching directive for federal agencies in April 2023. Additionally, CVE-2021-29256 represents a high-severity flaw affecting certain versions of the Bifrost and Midgard Arm Mali GPU kernel drivers, enabling an unprivileged user to access sensitive data and escalate privileges to the root level.

The Enduring Issue: Why Exposed Credentials Go Unaddressed—and Solutions for Change

May 12, 2025
Secrets Management / DevSecOps

Detecting leaked credentials is only part of the solution. The real challenge—and often the overlooked aspect—is the follow-up after detection. New insights from GitGuardian’s State of Secrets Sprawl 2025 report highlight a concerning trend: a significant number of exposed company secrets found in public repositories remain active for years post-discovery, expanding the attack surface that many organizations neglect. GitGuardian’s analysis of public GitHub repositories reveals that a worrisome percentage of credentials identified as far back as 2022 are still valid today. “Detecting a leaked secret is just the beginning,” notes GitGuardian’s research team. “The true test is prompt remediation.”

Ex-Black Basta Members Employ Microsoft Teams and Python Scripts in 2025 Cyber Attacks

June 11, 2025
Ransomware / Cybersecurity

Former affiliates of the Black Basta ransomware group are reportedly sticking to familiar tactics, utilizing email bombing and Microsoft Teams phishing to gain sustained access to targeted networks. Recent reports from ReliaQuest, shared with The Hacker News, reveal that attackers have begun incorporating Python script execution along with these methods, using cURL requests to retrieve and deploy malicious payloads. This evolution indicates that threat actors are adapting and reorganizing despite challenges faced by the Black Basta identity following the public leak of its internal communications earlier this February. The cybersecurity firm found that 50% of Teams phishing incidents recorded between February and May 2025 originated from onmicrosoft[.]com domains, with breached domains contributing to 42% of all attacks during that timeframe. This approach proves particularly stealthy, enabling attackers to masquerade as legitimate traffic.

BlackByte 2.0 Ransomware: Rapid Infiltration, Data Encryption, and Extortion in Just 5 Days

Published: Jul 07, 2023
Category: Endpoint Security / Ransomware

Ransomware attacks pose a severe challenge for organizations globally, and the threat level continues to escalate. Recently, Microsoft’s Incident Response team delved into the BlackByte 2.0 ransomware attacks, revealing the alarming speed and destructive impact of these cyber assaults. Their findings underscore that cybercriminals can execute a complete attack—from initial infiltration to inflicting considerable damage—in just five days. Hackers swiftly breach systems, encrypt critical data, and demand ransom for its release. This drastically reduced timeline presents significant hurdles for organizations striving to bolster their defenses against such threats. BlackByte ransomware operates in the final phase of the attack, employing an 8-digit key to encrypt files. The investigation highlighted that attackers leverage a potent mix of tactics, particularly exploiting unpatched Microsoft Exchange Servers.

Türkiye-Based Hackers Exploit Zero-Day in Output Messenger to Deploy Golang Backdoors on Kurdish Servers

May 13, 2025
Category: Zero-Day / Vulnerability

A Türkiye-linked threat actor has exploited a zero-day vulnerability in the Indian enterprise communication tool Output Messenger as part of a cyber espionage campaign that began in April 2024. According to the Microsoft Threat Intelligence team, these exploits have led to the collection of sensitive user data from targets in Iraq. The focus of the attacks appears to align with the Kurdish military in Iraq, consistent with the previously documented objectives of the group known as Marbled Dust. This threat group, which has also been referred to as Silicon, Cosmic Wolf, Sea Turtle, Teal Kurma, and UNC1326, has been active since at least 2017. However, it wasn’t until 2019 that Cisco Talos documented their activities against both public and private entities in the Middle East and North Africa. Early last year, the group was also noted for targeting telecommunications and media sectors.
