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.

Google Addresses Critical Vulnerabilities in Latest Android Update

On July 7, 2023, Google rolled out its monthly security updates for the Android operating system, patching a total of 46 newly identified vulnerabilities. Notably, three of these vulnerabilities have been confirmed as actively exploited in specific targeted attacks, raising concerns among cybersecurity experts and business owners alike.

Among the most serious vulnerabilities is CVE-2023-26083, a memory leak flaw linked to the Arm Mali GPU driver utilized in Bifrost, Avalon, and Valhall chips. This particular weakness was exploited to launch a spyware attack on Samsung devices in December 2022, allowing cybercriminals to infiltrate sensitive information systems. The severity of this vulnerability prompted the Cybersecurity and Infrastructure Security Agency (CISA) to issue an urgent patching order for federal agencies back in April 2023, underscoring the potential risks faced by users and organizations dependent on affected devices.

Another critical vulnerability, tracked as CVE-2021-29256, impacts specific versions of the Bifrost and Midgard Arm Mali GPU kernel drivers. This high-severity flaw allows unprivileged users to gain unauthorized access to sensitive data and escalate their privileges to root levels. The implications of this vulnerability are vast, particularly for enterprise systems where safeguarding sensitive information is paramount.

Given the context of these vulnerabilities, the targeted attacks appear to align with tactics outlined in the MITRE ATT&CK framework. Initial access and privilege escalation tactics are particularly pertinent, suggesting that attackers may utilize techniques such as exploiting software flaws or leveraging social engineering to compromise systems. Persistence methods could also be employed, allowing attackers to maintain their foothold within compromised networks.

The recent updates by Google serve as a crucial reminder for businesses to remain vigilant regarding cybersecurity threats. As software vulnerabilities are discovered and exploited, the potential for targeted attacks increases dramatically. It is essential for organizations to prioritize timely software updates and patches, along with comprehensive risk assessments to mitigate the effects of such vulnerabilities.

The risk landscape associated with these vulnerabilities necessitates a proactive approach from IT departments and business owners. Monitoring updates and understanding the underlying risks can aid in developing strategies to defend against cyber threats. In an environment where cyberattacks are increasing in frequency and sophistication, preparedness is key.

As the cybersecurity landscape evolves, remaining informed about potential threats and ongoing vulnerabilities will be crucial for businesses looking to protect their assets. Robust cybersecurity practices coupled with timely software updates will play a significant role in safeguarding against the exploitation of identified vulnerabilities like those recently disclosed by Google.

Network Security / Threat Intelligence

The Chinese state-sponsored group known as Mustang Panda has been connected to a series of sophisticated, targeted attacks aimed at European foreign affairs entities since January 2023. According to researchers Itay Cohen and Radoslaw Madej from Check Point, these intrusions involve a custom firmware implant specifically designed for TP-Link routers. This implant includes several malicious components, featuring a custom backdoor dubbed “Horse Shell” that allows attackers to maintain persistent access, establish anonymous infrastructure, and facilitate lateral movement within compromised networks. Furthermore, the implant’s firmware-agnostic design enables its components to be integrated into various firmware from different vendors. The Israeli cybersecurity firm is monitoring this threat group, also known as Camaro Dragon, along with other aliases such as BASIN, Bronze President, Earth Preta, HoneyMyte, RedDelta, and Red Lich.

Rising China-Taiwan Tensions Ignite Sharp Increase in Cyber Attacks

Recent geopolitical strains between China and Taiwan have led to a significant rise in cyber attacks targeting the island nation. According to a report from the Trellix Advanced Research Center, “The conflict stemming from China’s claim over Taiwan, combined with Taiwan’s push for independence, has resulted in a troubling escalation of cyber threats.” These attacks, aimed at various sectors, primarily focus on deploying malware and stealing sensitive data. The cybersecurity firm noted a staggering four-fold increase in malicious emails between April 7 and April 10, 2023, with sectors such as networking, manufacturing, and logistics being particularly affected. Following this surge, the region saw a 15x spike in PlugX detections between April 10 and April 12, 2023.

Beware the ZIP File: Phishers Exploit .ZIP Domains to Deceive Victims

Cyber Threat / Online Security

A new phishing technique dubbed “file archiver in the browser” is being used to imitate file archiver software, such as WinRAR, within web browsers when victims visit a .ZIP domain. Security researcher mr.d0x revealed that this phishing attack involves creating a realistic landing page using HTML and CSS to mimic genuine file archive software, hosted on a .ZIP domain to enhance its legitimacy.

In a typical attack, cybercriminals can redirect users to a credential theft page when they click on a file that appears to be included within the fake ZIP archive. Another alarming tactic involves listing a harmless non-executable file, only for the actual download to be an executable file instead, as noted by mr.d0x…

Dark Pink APT Group Utilizes TelePowerBot and KamiKakaBot in Complex Campaigns

On May 31, 2023, it was reported that the Advanced Persistent Threat (APT) group known as Dark Pink has launched five new attacks targeting various organizations in Belgium, Brunei, Indonesia, Thailand, and Vietnam between February 2022 and April 2023. The targets include educational institutions, government agencies, military organizations, and non-profit entities, highlighting the group’s ongoing focus on high-value assets. Also referred to as the Saaiwc Group, Dark Pink is believed to originate from the Asia-Pacific region, primarily directing its attacks towards East Asia, with some activity observed in Europe. The group employs a variety of custom malware tools, including TelePowerBot and KamiKakaBot, to facilitate the exfiltration of sensitive data from compromised systems. “The group uses a range of sophisticated custom tools and deploys multiple kill chains, often leveraging spear-phishing emails,” noted Andrey Polovinkin, a security researcher at Group-IB, in a technical report.
