  • Budget Samsung phones shipped with unremovable spyware, say researchers

    Budget Samsung phones shipped with unremovable spyware, say researchers

    A controversy over data-gathering software secretly installed on Samsung phones has erupted again after a new accusatory post appeared on X last week.

    In the post on the social media site, cybersecurity newsletter International Cyber Digest warned about a secretive application called AppCloud that Samsung had allegedly put on its phones. The software was, it said,

    “unremovable Israeli spyware.”

    This all harks back to May, when digital rights group SMEX published an open letter to Samsung. It accused the company of installing AppCloud on its Galaxy A and M series devices, although stopped short of calling it spyware, opting for the slightly more diplomatic “bloatware”.

    The application, apparently installed on phones in West Asia and North Africa, did more than just take up storage space, though.According to SMEX, it collected sensitive information, including biometric data and IP addresses.

    SMEX’s analysis says the software, developed by Israeli company ironSource, is deeply integrated into the device’s operating system. You need root access to remove it, and doing so voids the warranty.

    Samsung has partnered with ironSource since 2022, carrying the its Aura toolkit for telecoms companies and device maker in more than 30 markets, including Europe. The pair expanded the partnership in November 2022—the same month that US company Unity Technologies (that makes the Unity game engine) completed its $4.4bn acquisition of ironSource. That expansion made ironSource

    “Samsung’s sole partner on newly released A-series and M-series mobile devices in over 50 markets across MENA – strengthening Aura’s footprint in the region.”

    SMEX’s investigation of ironSource’s products points to software called Install Core. It cites our own research of this software, which is touted as an advertising technology platform, but can install other products without the user’s permission.

    AppCloud wasn’t listed on the Unity/Ironsource website this February when SMEX wrote its in-depth analysis. It still isn’t. It also doesn’t appear on the phone’s home screen. It runs quietly in the background, meaning there’s no privacy policy to read and no consent screen to click, says SMEX.

    Screenshots shared online suggest AppCloud can access network connections, download files at will, and prevent phones from sleeping. However, this does highlight one important aspect of this software: While you might not be able to start it from your home screen or easily remove it, you can disable it in your application list. Be warned, though; it has a habit of popping up again after system updates, say users.

    Not Samsung’s first privacy controversy This isn’t Samsung’s first controversy around user privacy. Back in 2015, it was criticized for warning users that some smart TVs could listen to conversations and share them with third parties.

    Neither is it the first time that budget phone users have had to endure pre-installed software that they might not have wanted. In 2020, we reported on malware that was pre-installed on budget phones made available via the US Lifeline program.

    In fact, there have been many cases of pre-installed software on phones that are identifiable as either malware or potentially unwanted programs. In 2019, Maddie Stone, a security researcher for Google’s Project Zero, explained how this software makes its way onto phones before they reach the shelves. Sometimes, phone vendors will put malware onto their devices after being told that it’s legitimate software, she warned. This can result in botnets like Chamois, which was built on pre-installed malware purporting to be from an SDK.

    One answer to this problem is to buy a higher-end phone, but you shouldn’t have to pay more to get basic privacy. Budget users should expect the same level of privacy as anyone else.

  • 16-Year-Old Security Bug Affects Millions of HP, Samsung, Xerox Printers

    Details have emerged about a high severity security vulnerability affecting a software driver used in HP, Xerox, and Samsung printers that has remained undetected since 2005.

    Tracked as CVE-2021-3438 (CVSS score: 8.8), the issue concerns a buffer overflow in a print driver installer package named “SSPORT.SYS” that can enable remote privilege and arbitrary code execution. Hundreds of millions of printers have been released worldwide to date with the vulnerable driver in question.

    However, there is no evidence that the flaw was abused in real-world attacks.

    “A potential buffer overflow in the software drivers for certain HP LaserJet products and Samsung product printers could lead to an escalation of privilege,” according to an advisory published in May.

    The issue was reported to HP by threat intelligence researchers from SentinelLabs on February 18, 2021, following which remedies have been published for the affected printers as of May 19, 2021.

    CVE-2021-3438

    Specifically, the issue hinges on the fact that the printer driver doesn’t sanitize the size of the user input, potentially allowing an unprivileged user to escalate privileges and run malicious code in kernel mode on systems that have the buggy driver installed. now

    “The vulnerable function inside the driver accepts data sent from User Mode via IOCTL (Input/Output Control) without validating the size parameter,” SentinelOne researcher Asaf Amir said in a report shared with The Hacker News. “This function copies a string from the user input using ‘strncpy‘ with a size parameter that is controlled by the user. Essentially, this allows attackers to overrun the buffer used by the driver.”

    Interestingly, it appears that HP copied the driver’s functionality from a near-identical Windows driver sample published by Microsoft, although the sample project in itself doesn’t contain the vulnerability.

    This is not the first time security flaws have been discovered in old software drivers. Earlier this May, SentinelOne revealed details about multiple critical privilege escalation vulnerabilities in Dell’s firmware update driver named “dbutil_2_3.sys” that went undisclosed for more than 12 years.
