Google Patches Android Zero-Day Flaws Used to Unlock Phones

 

Google recently addressed critical security flaws in Android that allowed authorities to unlock phones using forensic tools, according to a report by Amnesty International. The report, released on Friday, detailed three previously unknown vulnerabilities exploited by phone-unlocking company Cellebrite. Amnesty’s researchers discovered these flaws while investigating the hacking of a student protester’s phone in Serbia. Since the vulnerabilities were found in the core Linux USB kernel, they could have potentially affected over a billion Android devices. 

Zero-day vulnerabilities, which remain unknown to software and hardware makers until discovered, are particularly dangerous as they can be exploited without any existing patches. Amnesty first noticed traces of one such flaw in mid-2024. Later, while examining the phone of an activist in Serbia, the organization shared its findings with Google’s Threat Analysis Group. This led Google to identify and fix the three security loopholes. During its investigation, Amnesty found that Serbian authorities had used Cellebrite’s forensic tools to exploit a USB vulnerability, allowing them to bypass security measures and unlock the activist’s device. 

Amnesty had previously reported in December that Serbian officials had used similar tools to access the phones of both an activist and a journalist, later installing the Android spyware NoviSpy. Following these allegations, Cellebrite stated earlier this week that it had discontinued its services for its Serbian customers. A Cellebrite spokesperson, Victor Cooper, pointed to a company statement that acknowledged the Amnesty report. The statement emphasized that Cellebrite had reviewed the allegations from Amnesty’s December 2024 report and conducted an internal investigation. As a result, the company decided to halt the use of its products by the Serbian authorities. 

In January, Amnesty was contacted to analyze another case involving a youth activist who was arrested by Serbia’s Security Information Agency (BIA) late last year. According to the report, the circumstances of his arrest and the actions of BIA officers closely resembled previous incidents documented in Amnesty’s December findings. A forensic analysis of the activist’s device confirmed that Cellebrite’s tools had been used to unlock his Samsung A32 without consent or legal authorization.  

Amnesty condemned the use of Cellebrite’s technology against individuals engaging in peaceful protests and exercising their right to free expression, stating that such actions violate human rights laws. Bill Marczak, a senior researcher at Citizen Lab, advised activists, journalists, and civil society members to consider switching to iPhones, which may offer stronger protection against these types of exploits. Amnesty’s Security Lab head, Donncha Ó Cearbhaill, warned thatCellebrite’s widespread availability raises serious concerns, suggesting that the full extent of its misuse may still be unknown. 

Google has not yet responded to requests for comment regarding the issue.

Researcher Saves Six Companies from Ransomware by Exploiting Security Flaws in Ransomware Gangs’ Infrastructure

 

A security researcher has revealed that six companies were saved from potentially paying significant ransom demands due to security flaws found in the web infrastructure of the ransomware gangs targeting them. In a rare win for the victim organizations, two companies received decryption keys that allowed them to restore their data without paying a ransom, while four hacked cryptocurrency companies were alerted before the ransomware gang could begin encrypting their files.  

Stykas, a security researcher and chief technology officer at Atropos.ai, conducted a research project aimed at identifying the command and control servers behind more than 100 ransomware and extortion-focused groups and their data leak sites. His goal was to find vulnerabilities that could expose information about these gangs, including details about their victims. Stykas disclosed his findings to TechCrunch ahead of his presentation at the Black Hat security conference in Las Vegas. He identified several rookie security flaws in the web dashboards used by at least three ransomware gangs, which were sufficient to compromise the inner workings of their operations. 

Ransomware gangs typically conceal their identities and activities on the dark web, an anonymous section of the internet accessible through the Tor browser. This anonymity makes it difficult to trace the real-world servers used for cyberattacks and the storage of stolen data. However, coding errors and security vulnerabilities in the leak sites used by these gangs to extort victims by publishing stolen files allowed Stykas to access information about their operations without needing to log in. In some cases, the bugs exposed the IP addresses of the leak site’s servers, providing a way to trace their real-world locations. For instance, Stykas discovered that the Everest ransomware gang was using a default password to access its back-end SQL databases, exposing its file directories. 

Additionally, exposed API endpoints revealed the targets of the BlackCat ransomware gang’s attacks while they were still in progress. Stykas also identified an insecure direct object reference (IDOR) vulnerability, which he used to access and cycle through the chat messages of a Mallox ransomware administrator. Through this, he discovered two decryption keys that he shared with the affected companies. The researcher informed TechCrunch that the victims included two small businesses and four cryptocurrency companies, two of which were unicorns—startups with valuations exceeding $1 billion. However, he declined to name the companies involved. He also noted that none of the companies he notified have publicly disclosed the security incidents, though he did not rule out revealing their names in the future. 

The FBI and other government authorities have long advised victims of ransomware not to pay ransoms, as doing so only incentivizes cybercriminals. However, this advice often leaves companies with few options to regain access to their data or resume operations. Law enforcement agencies have occasionally succeeded in compromising ransomware gangs to obtain decryption keys and cut off their illegal revenue streams, though these efforts have had mixed results. 

Stykas’ research underscores that ransomware gangs can be vulnerable to the same basic security flaws that affect large companies. This presents a potential opportunity for law enforcement to target these criminal hackers, even when they operate outside of traditional jurisdictional reach.

Microsoft Uncovers Major Security Flaw in Android Apps with Billions of Downloads

 

Microsoft recently made a troubling discovery regarding the security of numerous Android applications, including some of the most widely used ones, each boasting over 500 million installations. After uncovering a common security weakness, Microsoft promptly notified Google's Android security research team, prompting Google to release new guidance aimed at helping Android app developers identify and rectify the issue. 
 
Among the applications found to be vulnerable were Xiaomi Inc.'s File Manager, boasting over 1 billion installations, and WPS Office, with around 500 million downloads. Although Microsoft confirms that the vendors of these products have since addressed the issue, they caution that there may be other apps out there still susceptible to exploitation due to the same security flaw. 
 
The vulnerability in question pertains to Android applications that share files with other apps. To enable secure sharing, Android employs a feature known as "content provider," which essentially serves as an interface for managing and exposing an app's data to other installed applications on the device. 
 
However, Microsoft's research uncovered a significant oversight in many cases: when an Android app receives a file from another app, it often fails to adequately validate the content. Particularly concerning is the practice of using the filename provided by the sending application to cache the received file within the receiving application's internal data directory. This oversight creates an opportunity for attackers to exploit the system by sending a file with a malicious filename directly to a receiving app, without the user's knowledge or consent. 
 
Typical targets for such file sharing include email clients, messaging apps, networking apps, browsers, and file editors. If a malicious filename is received, the receiving app may unwittingly initialize the file, triggering processes that could lead to compromise. 
 
The potential consequences vary depending on the specific implementation of the Android application. In some scenarios, attackers could exploit the vulnerability to overwrite an app's settings, leading to unauthorized communication with attacker-controlled servers or the theft of user authentication tokens and other sensitive data. In more severe cases, attackers could inject malicious code into a receiving app's native library, enabling arbitrary code execution. 
 
Microsoft and Google have both offered guidance to developers on how to address this issue, emphasizing the importance of validating file content and ensuring the secure handling of shared files. Meanwhile, end users can mitigate the risk by keeping their Android apps up to date and exercising caution when installing apps from sources they trust.
