The Rise of Malicious Apps: A New Battleground in the Israeli Attack Detector Conflict

Cybersecurity in the Midst of Conflict: Malicious Apps Target Users in Israel-Gaza Region

The Initial Malicious App

Cloudflare, a cybersecurity company, recently discovered a malicious app that targeted users in the Israel and Gaza region during the ongoing conflict. The app, called RedAlert – Rocket Alerts, is a genuine app that allows individuals to receive timely alerts about incoming airstrikes. However, a malicious version of the app was detected last week, which collected personal information including access to contacts, call logs, SMS, account information, and a list of other installed apps.

The website hosting the malicious app was created on October 12th but has since been taken offline. Only users who installed the Android version of the app are impacted, and they are urgently advised to delete the app.

Exploiting Fear and Authenticity

According to Cloudflare, creating a malicious app that spoofs a known brand is a common tactic used by cybercriminals. They often disguise malicious apps with names, images, or descriptions similar to popular or malware-free apps to deceive users. In this case, the malicious app mimicked a widely used app during a time of distress, when services like this are heavily relied upon. Cloudflare states that this is “another example of threat attackers leveraging authenticity to carry out impactful attacks.”

Casey Ellis, founder and CTO of Bugcrowd, believes that there will be more cases like this where the Gaza conflict is used as a lure for malware. Attackers constantly look for events that create fear, uncertainty, and a volatile information environment, and the Israel-Hamas conflict meets these criteria.

It is important to note that Cloudflare was unable to attribute the malicious app to any specific threat actor, and there is no evidence that it was created by someone from the Middle East. It could be the work of an unrelated cybercriminal looking to exploit the conflict for their malicious gain.

More Than One Incident

In a separate incident, the pro-Palestinian hacktivist group AnonGhost exploited a vulnerability in another app called Red Alert: Israel. This allowed the group to intercept requests, expose servers and APIs, and send fake alerts to some app users, including a message that a nuclear bomb strike was imminent.

This incident highlights the diversity of actions that attackers can take. Hacktivists are typically associated with conducting small-scale DDoS attacks and defacement, but in this case, their actions were far more devastating and costly. It is crucial for organizations to map and mitigate the risk of hacktivism as part of their threat intelligence program.

The Ease of App Spoofing

Krishna Vishnubhotla, vice president of product strategy at Zimperium, explains that spoofing mobile apps is easy because many app teams inadvertently provide threat actors with a blueprint for abuse. Developers often focus on code optimization and speed to market, neglecting sufficient threat visibility and protection for their apps once they are published. Threat actors take advantage of this by using reverse engineering to understand an app’s inner workings and create spoofed versions.

To protect against malicious apps, Arctic Wolf recommends checking the app’s developers and reviews, restricting permissions when necessary, and downloading apps only from reputable developers. Group-IB advises organizations to carefully examine and fortify their web-facing applications, as hacktivists often exploit web and mobile APIs that are seen as softer targets compared to principal product APIs.

Trust, but Verify

Casey Ellis emphasizes the need to “trust, but verify” when it comes to protecting against malicious apps. Users should double-check before trusting anything that claims to assist in personal safety, and triple-check before sharing it with others. In this case, the malicious apps were downloaded by people in a state of concern and potentially without the usual careful consideration.

Editorial: The Exploitation of Human Vulnerability

The incidents of malicious apps targeting users in the Israel-Gaza region during the conflict are deeply concerning. Cybercriminals are taking advantage of a population already under immense stress and fear, exploiting the need for safety and information. This highlights the ruthless nature of cybercrime, where no event or situation is off-limits for attackers.

These incidents serve as a reminder of the importance of strong cybersecurity measures, not only for critical infrastructure but also for individuals accessing apps and information on their smartphones. Users must always be cautious and skeptical of apps claiming to offer assistance during times of conflict or crisis.

Advice for Users and Organizations

For users, it is essential to exercise caution when downloading apps. Here are some recommendations:

1. Verify the App’s Developers and Reviews:

Check the credibility of the app’s developers and read reviews from other users. Look for any mentions of scams or malicious activity in the reviews.

2. Restrict App Permissions:

Review and restrict app permissions when necessary. Be cautious about granting access to sensitive information or functionalities.

3. Download Apps from Reputable Developers:

Stick to downloading apps from well-known and trusted developers. Avoid apps from unfamiliar or suspicious sources.

For organizations, here are some guidelines to mitigate the risk of hacktivism:

1. Fortify Web-Facing Applications:

Carefully examine and strengthen the security of all web-facing applications. Hacktivists often target these applications as they are perceived as softer targets compared to principal product APIs.

2. Ensure Threat Visibility and Protection:

Don’t neglect threat visibility and protection once an app is published. Implement robust security measures to prevent reverse engineering and the creation of spoofed versions.

In the face of increasingly sophisticated cyber threats, ongoing vigilance, and adherence to best practices in cybersecurity are crucial. Whether during times of conflict or in daily life, protecting oneself from cyber threats remains a priority.
