Apple Security Advisory 2023-09-21-1

Tibetan, Uyghur, and Taiwanese individuals and organizations are the targets of a persistent campaign orchestrated by a threat actor codenamed EvilBamboo to gather sensitive information.
"The attacker has created fake Tibetan websites, along with social media profiles, likely used to deploy browser-based exploits against targeted users," Volexity security researchers Callum Roxan, Paul

Tibetan, Uyghur, and Taiwanese individuals and organizations are the targets of a persistent campaign orchestrated by a threat actor codenamed **EvilBamboo** to gather sensitive information.

"The attacker has created fake Tibetan websites, along with social media profiles, likely used to deploy browser-based exploits against targeted users," Volexity security researchers Callum Roxan, Paul Rascagneres, and Thomas Lancaster said in a report published last week.

"Partly through impersonating existing popular communities, the attacker has built communities on online platforms, such as Telegram, to aid in distribution of their malware."

EvilBamboo, formerly tracked by the cybersecurity firm under the name Evil Eye, has been linked to multiple attack waves since at least 2019, with the threat actor leveraging watering hole attacks to deliver spyware targeting Android and iOS devices. It's also known as Earth Empusa and POISON CARP.

The intrusions directed against the Apple mobile operating system leveraged a then-zero-day vulnerability in the WebKit browser engine that was patched by Apple in early 2019 to deliver a spyware strain called Insomnia. Meta, in March 2021, said it detected the threat actor abusing its platforms to distribute malicious websites hosting the malware.

The group is also known to use Android malware such as ActionSpy and PluginPhantom to harvest valuable data from compromised devices under the guise of dictionary, keyboard, and prayer apps made available on third-party app stores.

The latest findings from Volexity attribute to EvilBamboo three new Android espionage tools, namely BADBAZAAR, BADSIGNAL, and BADSOLAR, the first of which was documented by Lookout in November 2022.

A subsequent report from ESET last month detailed two trojanized apps masquerading as Signal and Telegram on the Google Play Store to entice users into installing BADSIGNAL. While the Slovak cybersecurity firm assigned the bogus to the BADBAZAAR family, citing code similarities, Volexity said, "they also appear to be divergent in their development and functionality."

Attack chains used to distribute the malware families entail the use of APK sharing forums, fake websites advertising Signal, Telegram, and WhatsApp, Telegram channels devoted to sharing Android apps, and a set of bogus profiles on Facebook, Instagram, Reddit, X (formerly Twitter), and YouTube.

"The Telegram variants implement the same API endpoints as the Signal variants to gather information from the device and they implement a proxy," the researchers said, adding it identified endpoints indicating the existence of an iOS version of BADSIGNAL.

One of the Telegram channels is also said to have contained a link to an iOS application named TibetOne that's no longer available in the Apple App Store.

Messages shared via the Telegram groups have also been used to distribute applications backdoored with the BADSOLAR malware as well as booby-trapped links that, when visited, run malicious JavaScript to profile and fingerprint the system.

While BADBAZAAR is mainly used to target Uyghur and other individuals of the Muslim faith, BADSOLAR appears to be used primarily with apps that are Tibetan-themed. However, both strains incorporate their malicious capabilities in the form of a second stage that's retrieved from a remote server.

BADSOLAR's second-stage malware is also a fork of an open-source Android remote access trojan called AndroRAT. BADSIGNAL, in contrast, packs all of its information-gathering functions in the main package itself.

"These campaigns largely rely on users installing backdoored apps, which highlights both the importance of only installing apps from trusted authors and the lack of effective security mechanisms to stop backdoored apps making their way on to official app stores," the researchers said.

"EvilBamboo's creation of fake websites, and the personas tailored to the specific groups they target, has been a key aspect of their operations, enabling them to build trusted communities that provide further avenues to target individuals with their spyware or for other exploitation."

A week in security (September 18 - September 24)

By Waqas
Former Egyptian MP targeted with predator spyware ahead of 2024 presidential run - Therefore, Update your macOS Ventura, iOS, and iPadOS devices NOW, as Apple has released emergency updates to address the flaws.
This is a post from HackRead.com Read the original post: Zero-Day iOS Exploit Chain Infects Devices with Predator Spyware

****Key Findings****

*   **Ahmed Eltantawy, a former Egyptian MP and presidential candidate, was targeted with Cytrox’s Predator spyware after announcing his bid for the presidency.**

*   **The spyware was delivered through SMS, WhatsApp messages, and network injection attacks, highlighting the advanced tactics used against Eltantawy.**

*   **Researchers obtained an iPhone zero-day exploit chain used to install Predator on iOS devices, affecting versions through 16.6.1.**

*   **The network injection attack was attributed with high confidence to the Egyptian government, as it originated from a device physically located within Egypt.**

*   **This case raises concerns about the lack of controls on the export of spyware technologies and underscores the importance of security updates and lockdown modes on Apple devices.**

In a recent investigation by Citizen Lab, alarming findings reveal that former Egyptian Member of Parliament, Ahmed Eltantawy, was the victim of a sophisticated cyber espionage campaign that leveraged Cytrox’s Predator spyware.

This targeting occurred between May and September 2023, shortly after Eltantawy publicly announced his intention to run for President in the 2024 Egyptian elections.

Here, it is worth noting that Cytrox’s Predator spyware was initially discovered targeting Android devices **in May 2022**. However, in August 2022, Citizen Lab **pointed out** a connection between the spyware and the European spyware vendor, Intellexa Alliance.

At that time, the spyware was used to target a lawmaker in Greece, and interestingly, the same firm had previously **made headlines in November 2019** when Cypriot authorities seized a surveillance van belonging to Intellexa. This surveillance van was equipped with hacking tools capable of intercepting, cracking, and tracking smartphones.

The campaign against Eltantawy utilized various tactics, including SMS and WhatsApp messages containing malicious links. Moreover, Eltantawy’s mobile connection with Vodafone Egypt was persistently selected for targeting via network injection.

When Eltantawy visited non-HTTPS websites, a device within Vodafone Egypt’s network automatically redirected him to a malicious website to infect his phone with Cytrox’s Predator spyware.

Citizen Lab’s **investigation** uncovered an iPhone zero-day exploit chain designed to install Predator on iOS versions through 16.6.1. They also obtained the first stage of the spyware, which shared notable similarities with a sample of Cytrox’s Predator spyware obtained in 2021. With high confidence, Citizen Lab attributes the spyware to Cytrox’s Predator spyware.

Given Cytrox’s known association with the Egyptian government, which is a customer of the Predator spyware, and the fact that the spyware was delivered via network injection from a device physically located within Egypt, Citizen Lab confidently attributes the network injection attack to the Egyptian government.

This isn’t the first time Eltantawy has been targeted. In November 2021, his phone was infected with Cytrox’s Predator spyware through a text message containing a link to a Predator website.

These revelations raise serious concerns about the use of spyware to target opposition figures in a democratic process. Ahmed Eltantawy’s case underscores the need for strong cybersecurity measures and heightened awareness of potential threats during election campaigns.

****Apple Releases Emergency Updates Amid Citizen Lab’s Disclosure****

In response to Citizen Lab’s findings, Apple has issued three emergency updates for iOS, iPadOS **(1)**, and macOS Ventura **(2)**. The updates address the following vulnerabilities:

*   CVE-2023-41991
*   CVE-2023-41992
*   CVE-2023-41993

Apple has also acknowledged the researchers’ findings and **stated** that the company is aware of reports suggesting that this issue may have been actively exploited in versions of iOS prior to iOS 16.7.

Commenting on this, **Dr Klaus Schenk**, senior vice president of security and threat research at Verimatrix, said “The vulnerabilities discovered in Apple’s platforms are highly concerning due to their potential impact. Privilege escalation, arbitrary code execution, and especially remote exploitable arbitrary code execution rank among the most dangerous issues for any computing system.”

Dr Klaus emphasised that “It’s reassuring that Apple has not yet disclosed technical details of the attack vectors. Keeping that information private significantly reduces the risk of widespread exploits, since threat actors have less information to engineer effective attacks. For remote code execution to occur, a user would need to visit a website specifically crafted to leverage these vulnerabilities and distribute malicious code. With details undisclosed, the number of sites currently capable of mounting such an attack is likely very low.”

“That said, Apple customers should immediately install these emergency security updates to protect themselves against potential targeted attacks. Timely patching is critical, as threat actors will eventually reverse engineer the fixes to understand the underlying flaws. By updating promptly, users ensure their devices cannot be compromised by attacks exploiting these particular zero-day vulnerabilities, he advised.” “Moving forward, it’s essential that Apple continue working diligently to identify and rectify security issues in their software before they can be weaponised against users.”

This marks the second time in a month that Citizen Lab has detected a sophisticated spyware campaign targeting Apple devices. **On September 7th, 2023**, Apple released a critical security update to address a zero-click vulnerability that was actively delivering NSO Group’s Pegasus spyware to iPhones. These revelations were initially reported by Citizen Lab, which classified the attack as a BLASTPASS operation.

****Conclusion****

The Citizen Lab’s findings also shed light on the importance of maintaining up-to-date software and enabling security features like Lockdown Mode on Apple devices. They emphasize the critical role that security measures play in safeguarding individuals from cyber threats.

Additionally, the report calls for increased controls on the export of technologies that can be misused to violate human rights. It highlights the need for greater transparency and accountability in regulating dual-use technology exports, especially in cases involving companies headquartered in Canada.

In a world where cyber threats are becoming increasingly sophisticated, these findings serve as a stark reminder of the importance of digital security and the potential consequences of inadequate measures.

The post Emergency update! Apple patches three zero-days appeared first on Malwarebytes Labs.

Apple has released security updates for several products to address a handful of zero-day vulnerabilities that may already have been used by criminals. Updates are available for:

*   iOS 16.7 and iPadOS 16.7
*   iOS 17.0.1 and iPadOS 17.0.1
*   watchOS 9.6.3
*   watchOS 10.0.1
*   macOS Ventura 13.6
*   macOS Monterey 12.7
*   Safari 16.6.1

The updates may already have reached you in your regular update routines, but it doesn't hurt to check if your device is at the latest update level. If a Safari update is available for your device, you can get it by updating your iPhone or iPad or updating your Mac.

The Common Vulnerabilities and Exposures (CVE) database lists publicly disclosed computer security flaws. The CVEs patched in these updates are:

*   CVE-2023-41991, a certificate validation issue that could allow a malicious app to bypass signature validation.
*   CVE-2023-41992, a flaw that could be used by a local attacker to elevate their privileges.
*   CVE-2023-41993, a problem with processing web content that could be used for arbitrary code execution.

Apple states says that all these vulnerabilities may have been actively exploited against versions of iOS before iOS 16.7.

It’s important to note that CVE-2023-41993 is a vulnerability in WebKit. WebKit is the engine that powers the Safari web browser on Macs as well as all browsers on iOS and iPadOS (all web browsers on iOS and iPadOS are obliged to use it). It is also the web browser engine used by Mail, App Store, and many other apps on macOS, iOS, and Linux.

All three vulnerabilities were credited to the same researchers—Bill Marczak of The Citizen Lab at The University of Toronto's Munk School, and Maddie Stone of Google's Threat Analysis Group. The Citizen Lab is an interdisciplinary laboratory based at the Munk School of Global Affairs & Public Policy, University of Toronto, focusing on research and development at the intersection of information and communication technologies, human rights, and global security. It is renowned for its research of the use of spyware against journalists, activists, and dissidents.

About two weeks ago, we reported about two Apple issues that were added by CISA to its catalog of known exploited vulnerabilities. Those vulnerabilities were also discovered as zero-days by CitizenLab. Together, these two vulnerabilities were found to be used in an attack chain dubbed BLASTPASS. The exploit chain was capable of compromising iPhones running the latest version of iOS (16.6) without any interaction from the victim and was reportedly used by the NSO Group to deliver the Pegasus spyware.

It is not hard to see how these three new vulnerabilities could be used to compromise a device just by viewing specially crafted malicious web content, so it’s highly recommended to install these updates at your earliest convenience, especially iPhone users with a high profile threat model.
