A healthy percentage of Android users targeted by mobile malware or mobile adware last year suffered a system partition infection, making the malicious files virtually undeletable. That’s according to research from Kaspersky, which found that 14.8 percent of its users who suffered such attacks were left with undeletable files. These range from trojans that can install and run apps without the user’s knowledge, to less threatening, but nevertheless intrusive, advertising apps. “A system partition infection entails a high level of risk for the users of infected devices, as a security solution cannot access the system directories, meaning it cannot remove the malicious files,” the firm explained, in a posting on Monday. Moreover, the research found that most devices harbor pre-installed default applications that are also undeletable – the number of those affected varies from 1 to 5 percent of users with low-cost devices and reaches 27 percent in extreme cases. “Infection can happen via two paths: The threat gains root access on a device and installs adware in the system partition, or the code for displaying ads gets into the firmware of the device before it even ends up in the hands of the consumer,” according to the firm. In the latter scenario, this could lead to potentially undesired and unplanned consequences. For instance, many smartphones have functions providing remote access to the device. If abused, such a feature could lead to a data compromise of a user’s device. Among the most common types of malware that Kaspersky has found installed in the system partition of Android smartphones are two older threats: The Lezok and Triada trojans. “The latter is notable for its ad code embedded not just anywhere, but directly in libandroid_runtime — a key library used by almost all apps on the device,” according to the analysis. However, examining victims’ system apps revealed a wide range of threats. The Agent trojan for instance is an obfuscated malware that usually hides in the app that handles the graphical interface of the system, or in the Settings utility, without which the smartphone cannot function properly. The malware delivers its payload, which in turn can download and run arbitrary files on the device. Then there’s the Sivu trojan, which is a dropper masquerading as an HTMLViewer app. “The malware consists of two modules and can use root permissions on the device,” according to Kaspersky. “The first module displays ads on top of other windows, and in notifications. The second module is a backdoor allowing remote control of the smartphone. Its capabilities include installing, uninstalling, and running apps, which can be used to covertly install both legitimate and malicious apps, depending on the intruder’s goals.” The Plague adware app is another common threat that Kaspersky found installed in the system partition. It pretends to be a legitimate system service, calling itself Android Services – but in reality, it can download and install apps behind the user’s back, as well as display ads in notifications. “What’s more, Plague.f can display ads in SYSTEM_ALERT_WINDOW — a pop-up window that sits on top of all apps,” explained the researchers. The Necro.d trojan is unusual because it’s a native library located in the system directory. Its launch mechanism is built into another system library, libandroid_servers.so, which handles the operation of Android services. “At the command of the command-and-control (C2), Necro.d can download, install, uninstall and run apps,” explained the researchers. “In addition, the developers decided to leave themselves a backdoor for executing arbitrary shell commands. On top of that, Necro.d can download Kingroot superuser rights utility — seemingly so that the OS security system does not interfere with delivering ‘very important’ content for the user.” Further details can be found on OUR FORUM.

Chinese manufacturing giant, Huawei, is doing quite well in the smartphone market. Oh yes, you read that right, the Chinese manufacturer’s smartphone business is growing. Despite the ban by the U.S. Huawei somehow managed to hold on to its own. Since the beginning of last year, the company had to manage American restrictions. Its devices can not use Google Play Services which means that its sales outside China would drop. However, for 2019, Huawei shipped about 240 million smartphones, its record high. Furthermore, the Chinese manufacturer also toppled Samsung in April. For April and May, Huawei is the number one smartphone manufacturer globally. However, there are forecasts that it may lose this position in June. Now, Huawei’s new tablet just got 3C certification. This is coming after two of its high-end chargers (66W & 65 GaN) got the certification. According to the certification, the new tablet comes with model number SCMR-W09. Furthermore, the certification also shows that Huawei’s new tablet supports 22.5W fast charging. Of course, its a tablet and we don’t expect it to come with Huawei’s high-end chargers. According to the listing, the applicant, and manufacturer of this Huawei tablet is Huawei Terminal Co., Ltd. The production plant is Xike Communication Technology Equipment (Heyuan) Co., Ltd while the certification date is June 22. The tablet manufacturing market is not as lucrative as the smartphone business. Presently, there are not many 5G tablets in the market. However, since the beginning of last year, Huawei has released two 5G tablets in the Chinese market – Huawei MatePad Pro 5G and Huawei MatePad. These tablets target different user markets. Among them, Huawei MatePad Pro 5G comes with a Kirin 990 5G SoC, supports 40W super-fast charging, 27W wireless fast charging, and 3D graphene cooling technology. As for the Huawei MatePad, it uses a Kirin 810 chip. It also comes with a built-in 7250 mAh battery that supports 18W fast charge. Turn to OUR FORUM to learn more.

The National Security Agency issued a new cybersecurity advisory on Thursday, warning that virtual private networks, or VPNs, could be vulnerable to attacks if not properly secured. The agency's warning comes amid a surge in telework as organizations adapt to coronavirus-related office closures and other constraints. A VPN allows users to establish private, encrypted connections to another network over the internet. They are used widely by corporations and other organizations to protect proprietary data from hackers while employees work remotely. A senior NSA official who briefed reporters Wednesday said the increase in remote work had attracted the attention of potentially malicious cyber actors.  "We certainly see adversaries focused on telework infrastructure," the official said. "We've seen exploitation and as a result, have felt that this was a product that is particularly helpful now." VPN gateways in particular are "prone to network scanning, brute force attacks, and zero-day vulnerabilities," the NSA's advisory said. "[N]etwork administrators should implement strict traffic filtering rules to limit the ports, protocols, and IP addresses of network traffic to VPN devices." The senior official said the NSA, whose employees deal daily with highly classified materials and systems, had taken its own steps to adapt to the pandemic, reducing some of its workforce to "mission-essential" for several weeks and introducing social distancing measures within its outposts. The advisory was issued by the agency's Cybersecurity Directorate, which launched last October. Its mandate involves reinvigorating a set of missions the NSA has long had — protecting government and private sector systems — by accelerating, broadening, and "operationalizing" its dissemination of unclassified threat information, according to officials. The directorate has now issued over a dozen public advisories since its launch. In October, it warned that nation-state actors were targeting VPN devices. In January, it was behind the disclosure of a "critical vulnerability" in Microsoft's Windows 10 software — something the agency might have once exploited, instead, as a hacking tool. And in May, in another rare move, it named a Russian military hacking unit that was secretly accessing commonly used email software. "Attribution is always interesting," the senior NSA official said Wednesday. "We do it if we believe it creates a sense of urgency to address a vulnerability." The directorate's emphasis on information-sharing stems from a recognition that nation-states are getting more aggressive and more sophisticated in going after the government and non-government targets. Its leadership has said it is also a conscious effort to move away from stubborn perceptions that the agency is a secretive black box — or "No-Such-Agency," as the NSA has been labeled. (Its foreign intelligence mission — which involves intercepting signals and communications overseas — is likely to continue avoiding the public eye.) The agency has also broadened its presence on social media, launching an Instagram account, a dedicated Twitter account for the directorate, and even bringing its notoriously circumspect director to the platform. (Paul Nakasone has tweeted three times in three weeks.) For more turn to OUR FORUM for more complete details.

US Cyber Command said today that foreign state-sponsored hacking groups are likely to exploit a major security bug disclosed today in PAN-OS, the operating system running on firewalls and enterprise VPN appliances from Palo Alto Networks. "Please patch all devices affected by CVE-2020-2021 immediately, especially if SAML is in use," US Cyber Command said in a tweet today. "Foreign APTs will likely attempt [to] exploit soon," the agency added, referring to APT (advanced persistent threat), a term used by the cyber-security industry to describe nation-state hacker groups. US Cyber Command officials are right to be panicked. The CVE-2020-2021 vulnerability is one of those rare security bugs that received a 10 out of 10 scores on the CVSSv3 severity scale. A 10/10 CVSSv3 score means the vulnerability is both easy to exploit as it doesn't require advanced technical skills, and it's remotely exploitable via the internet, without requiring attackers to gain an initial foothold on the attacked device. In technical terms, vulnerability is an authentication bypass that allows threat actors to access the device without needing to provide valid credentials. Once exploited, the bug allows hackers to change PAN-OS settings and features. While changing OS features seems innocuous, and of little consequence, the bug is actually quite a major issue because it could be used to disable firewalls or VPN access-control policies, effectively disabling the entire PAN-OS devices. In a security advisory published today, Palo Alto Networks (PAN) said that mitigating factors include the fact that PAN-OS devices must be in a certain configuration for the bug to be exploitable. PAN engineers said the bug is only exploitable if the 'Validate Identity Provider Certificate' option is disabled and if SAML (Security Assertion Markup Language) is enabled. However, according to Will Dormann, vulnerability analyst for CERT/CC, several vendor manuals instruct PAN-OS owners to set up this exact particular configuration when using third-party identity providers -- such as using Duo authentication on PAN-OS devices, or third-party authentication solutions from Centrify, Trusona, or Okta. This means that while the vulnerability looks harmless at a first glance due to the complex configuration needed to be exploitable, there are likely quite a few devices configured in this vulnerable state, especially due to the widespread use of Duo authentication in the enterprise and government sector. At the time of writing, the number of vulnerable systems is estimated to be at most 4,200, according to Troy Mursch, co-founder of internet scanning and threat intel firm Bad Packets. "Of the 58,521 publicly accessible Palo Alto (PAN-OS) servers scanned by Bad Packets, 4,291 hosts were found using some type of SAML authentication," Mursch told ZDNet today. However, Mursch says that his company's scans can only tell if SAML authentication is enabled, but not if the second condition (Validate Identity Provider Certificate' option disabled) is also met. Owners of PAN-OS devices are advised to immediately review device configurations and apply the latest patches provided by Palo Alto Networks if their devices are running in a vulnerable state.

America’s former top trade negotiator Charlene Barshefsky said the Donald Trump administration had “no policy” on China. Perhaps the most obvious example has been its overtly hostile but ultimately directionless assault on mainland 5G pioneer Huawei. The US government has used cyberspying, hacking, “lawfare”, diplomacy and disinformation – just about every possible tactic – to discredit and undermine the telecoms company. Yet, in the latest twist to this long-standing saga, it will reverse a ban on US firms from working with Huawei to develop 5G infrastructure and protocols. The reversal comes after top US tech giants complained they had no choice but to work with the blacklisted Chinese company because the latter holds many key patents and has been integral to the development of 5G standard protocols. Such development has been in the works for many years, involving top global companies and many government agencies under the auspices of the 3rd Generation Partnership Project (3GPP), an international collaboration of seven telecoms standard development organizations responsible for evolving mobile system specifications. Conspicuously, agencies of the United States government have been absent from many of those key gatherings where international standards are developed and adopted. But Beijing, Huawei, and other Chinese tech companies have been among the most active participants, resulting in the leading role they now play. Since Trump took office, his administration realized too late that the US has lagged far behind in 5G. Its hostile strategy to undermine Huawei and other Chinese firms may at first make sense. But Huawei is too entrenched in the game to be just kicked out of it on the say-so of Uncle Sam. China’s road to 5G was the industrial policy at its most spectacular. In 2012, two years before China Mobile launched 4G services on the mainland, Chinese companies joined international initiatives such as 3GPP to research and develop 5G infrastructure. Today, the country accounts for 35 percent of 5G standard-essential patents. Of these, about 15 percent are owned by Huawei. By comparison, the share of US firms is estimated at about 13 percent. US officials should realize they are hurting their own industry and companies by blocking and punishing Huawei. Even if they manage to force some of its key allies to exclude the Chinese telecoms giant from their 5G projects, they will end up suffering delays and having to pay Huawei in terms of royalties. In light of the latest rule reversal and constructive meetings between the two countries’ top diplomats, it is time for both sides to reach an understanding to enable all hi-tech companies to compete fairly and reap the rewards of their pioneering efforts.

On May 6, 2002, Steve Jobs opened WWDC with a funeral for Classic Mac OS, 18 years later, OS X finally reached its own end of the road: the next version of macOS is not 10.16, but 11.0. OS X has one of the most fascinating family trees in technology; to understand its significance requires understanding each of its forebearers. Unix does refer to a specific operating system that originated in AT&T’s Bell Labs (the copyrights of which are owned by Novell), but thanks to a settlement with the U.S. government (that was widely criticized for going easy on the telecoms giant), Unix was widely-licensed to universities in particular. One of the most popular variants that resulted was the Berkeley Software Distribution (BSD), developed at the University of California, Berkeley. Today you can still run nearly any Unix program on macOS, but particularly with some of the security changes made in Catalina, you are liable to run into permissions issues, particularly when it comes to seamlessly link programs together. Mach was a microkernel developed at Carnegie Mellon University; the concept of a microkernel is to run the smallest amount of software necessary for the core functionality of an operating system in the most privileged mode and put all other functionality into less privileged modes. OS X doesn’t have a true microkernel — the BSD subsystem runs in the same privileged mode, for performance reasons — but the modular structure of a microkernel-type design makes it easier to port to different processor architectures, or remove operating system functionality that is not needed for different types of devices (there is, of course, lots of other work that goes into a porting a modern operating system; this is a dramatic simplification). The story of Steve Jobs’ visiting Xerox is as mistaken as it is well-known; the Xerox Alto and its groundbreaking mouse-driven graphical user interface were well-known around Silicon Valley, thanks to the thousands of demos the Palo Alto Research Center (PARC) did and the papers it had published. PARC’s problem is that Xerox cared more about making money from copy machines than in figuring out how to bring the Alto to market. That doesn’t change just how much of an inspiration the Alto was to Jobs in particular: after the visit, he pushed the Lisa computer to have a graphical user interface, and it was why he took over the Macintosh project, determined to make an inexpensive computer that was far easier to use than anything that had come before it. The Macintosh was not the first Apple computer: that was the Apple I, and then the iconic Apple II. What made the Apple II unique was its explicit focus on consumers, not businesses; interestingly, what made the Apple II successful was VisiCalc, the first spreadsheet application, which is to say that the Apple II sold primarily to businesses. Still, the truth is that Apple has been a consumer company from the very beginning. This is why the Mac is best thought of as the child of Apple and Xerox: Apple understood consumers and wanted to sell products to them, and Xerox provided the inspiration for what those products should look like. It was NeXTSTEP, meanwhile, that was the child of Unix and Mach: an extremely modular design, from its own architecture to its focus on object-oriented programming and its inclusion of different “kits” that were easy to fit together to create new programs. If one were to add iOS to the family tree I illustrated above, most would put it under Mac OS X; I think, though, iOS is best understood as another child of Classic Mac and NeXT, but this time the resemblance is to the Apple side of the family.
