New Bluetooth Flaw Let Hackers Take Over Android, Linux, macOS, and iOS Devices

A critical Bluetooth security flaw could be exploited by threat actors to take control of Android, Linux, macOS and iOS devices. Tracked as CVE-2023-45866, the issue relates to a case of authentication bypass that enables attackers to connect to susceptible devices and inject keystrokes to achieve code execution as the victim. "Multiple Bluetooth stacks have authentication bypass

Warning for iPhone Users: Experts Warn of Sneaky Fake Lockdown Mode Attack

A new "post-exploitation tampering technique" can be abused by malicious actors to visually deceive a target into believing that their Apple iPhone is running in Lockdown Mode when it's actually not and carry out covert attacks. The novel method, detailed by Jamf Threat Labs in a report shared with The Hacker News, "shows that if a hacker has already infiltrated your device, they can

Adobe, Apple, Google & Microsoft Patch 0-Day Bugs

Microsoft today issued software updates to fix at least five dozen security holes in Windows and supported software, including patches for two zero-day vulnerabilities that are already being exploited. Also, Adobe, Google Chrome and Apple iOS users may have their own zero-day patching to do.

On Sept. 7, researchers at Citizen Lab warned they were seeing active exploitation of a “zero-click,” zero-day flaw to install spyware on iOS devices without any interaction from the victim.

“The exploit chain was capable of compromising iPhones running the latest version of iOS (16.6) without any interaction from the victim,” the researchers wrote.

According to Citizen Lab, the exploit uses malicious images sent via iMessage, an embedded component of Apple’s iOS that has been the source of previous zero-click flaws in iPhones and iPads.

Apple says the iOS flaw (CVE-2023-41064) does not seem to work against devices that have its ultra-paranoid “Lockdown Mode” enabled. This feature restricts non-essential iOS features to reduce the device’s overall attack surface, and it was designed for users concerned that they may be subject to targeted attacks. Citizen Lab says the bug it discovered was being exploited to install spyware made by the Israeli cyber surveillance company NSO Group.

This vulnerability is fixed in iOS 16.6.1 and iPadOS 16.6.1. To turn on Lockdown Mode in iOS 16, go to Settings, then Privacy and Security, then Lockdown Mode.

Not to be left out of the zero-day fun, Google acknowledged on Sept. 11 that an exploit for a heap overflow bug in Chrome is being exploited in the wild. Google says it is releasing updates to fix the flaw, and that restarting Chrome is the way to apply any pending updates. Interestingly, Google says this bug was reported by Apple and Citizen Lab.

On the Microsoft front, a zero-day in Microsoft Word is among the more concerning bugs fixed today. Tracked as CVE-2023-36761, it is flagged as an “information disclosure” vulnerability. But that description hardly grasps at the sensitivity of the information potentially exposed here.

Tom Bowyer, manager of product security at Automox, said exploiting this vulnerability could lead to the disclosure of Net-NTLMv2 hashes, which are used for authentication in Windows environments.

“If a malicious actor gains access to these hashes, they can potentially impersonate the user, gaining unauthorized access to sensitive data and systems,” Bowyer said, noting that CVE-2023-36761 can be exploited just by viewing a malicious document in the Windows preview pane. “They could also conduct pass-the-hash attacks, where the attacker uses the hashed version of a password to authenticate themselves without needing to decrypt it.”

The other Windows zero-day fixed this month is CVE-2023-36802. This is an “elevation of privilege” flaw in the “Microsoft Streaming Service Proxy,” which is built into Windows 10, 11 and Windows Server versions. Microsoft says an attacker who successfully exploits the bug can gain SYSTEM level privileges on a Windows computer.

Five of the flaws Microsoft fixed this month earned its “critical” rating, which the software giant reserves for vulnerabilities that can be exploited by malware or malcontents with little or no interaction by Windows users.

According to the SANS Internet Storm Center, the most serious critical bug in September’s Patch Tuesday is CVE-2023-38148, which is a weakness in the Internet Connection Sharing service on Windows. Microsoft says an unauthenticated attacker could leverage the flaw to install malware just sending a specially crafted data packet to a vulnerable Windows system.

Finally, Adobe has released critical security updates for its Adobe Reader and Acrobat software that also fixes a zero-day vulnerability (CVE-2023-26369). More details are at Adobe’s advisory.

For a more granular breakdown of the Windows updates pushed out today, check out Microsoft Patch Tuesday by Morphus Labs. In the meantime, consider backing up your data before updating Windows, and keep an eye on AskWoody.com for reports of any widespread problems with any of the updates released as part of September’s Patch Tuesday.

Update: Mozilla also has fixed zero-day flaw in Firefox and Thunderbird, and the Brave browser was updated as well. It appears the common theme here is any software that uses a code library called “libwebp,” and that this vulnerability is being tracked as CVE-2023-4863.

“This includes Electron-based applications, for example – Signal,” writes StackDiary.com. “Electron patched the vulnerability yesterday. Also, software like Honeyview (from Bandisoft) released an update to fix the issue. CVE-2023-4863 was falsely marked as Chrome-only by Mitre and other organizations that track CVE’s and 100% of media reported this issue as “Chrome only”, when it’s not.”

Top Tips For Home Cybersecurity And Privacy In A Coronavirus-Impacted World (Part 1)

Welcome to the new normal. We’re all now living in a post-COVID-19 world characterized by uncertainty, mass home working and remote learning. The lines demarcating normal life have shifted abruptly – perhaps never to return. That’s not the worst that can happen, as we all know, but it does mean we all need to get used to new ways of living, working and studying from home. This has major implications for the online safety, security and privacy of our families.

To help you adapt to these new conditions while protecting what matters most, Trend Micro has developed a two-part blog series on “The New Normal.” Part 1 identifies the scope and specific cyber-threats of the new normal. Part 2 provides security tips and products to help address those threats.

What’s going on?

In April, nearly 300 million Americans were estimated to be in government-mandated lockdown. Even as some businesses, municipalities and states begin to relax these rules, experts have warned of subsequent waves of the virus, which could result in new localized lockdowns. In short, a lot of people will continue to work from home, while their children, also at home, attempt to study remotely from their mobile devices.

This has considerable implications for how we spend our time. Without that morning commute to work or school, more of it than ever will involve sitting in front of a desktop, laptop, tablet or smartphone screen. Even the smart TV is enlisted. Dangers include

Use of potentially insecure video conferencing applications. The number of daily meeting participants on Zoom surged from 10 million in December 2019 to roughly 200 million in March. Visits to P2P/torrent sites or platforms for adult content. In search of entertainment, bored kids or teens in your household may have more time and inclination to do this. Downloads of potentially malicious applications disguised as legitimate entertainment or gaming content. More online shopping and banking. June alone generated $73.2 billion in online spend, up 76.2% year-on-year. Whenever you shop or bank online, financial data is potentially exposed. Use of potentially insecure remote learning platforms. Educational mobile app downloads increased by a massive 1087% between March 2 and 16. The trend continues. Logging on to corporate cloud-based services. This includes Office 365, to do your job remotely, or using a VPN to connect directly into the office. For recreation, streaming and browsing on your smart TV. But even your smart TV is vulnerable to threats, as the FBI has warned.

Risky behavior

Unfortunately, the increase in working from home (WFH), especially for those not used to it, may lead to an increase in risky behavior, such as: using non-approved apps for work; visiting non work-related sites on work devices; and using personal devices to access work resources. Recent global Trend Micro research found that:

	80% have used their work laptop for personal browsing, with only 36% fully restricting the sites they visit. 56% of employees have used a non-work app on a corporate device, and 66% have uploaded corporate data to it. 39% often or always access corporate data from a personal device. 8% admit to watching adult content on their work laptop, and 7% access the dark web.

This is not about restricting your freedom to visit the sites you want to visit while at home. It’s about reducing the risk of exposing corporate data and systems to possible malware.

What are the bad guys doing?

Unsurprisingly, there has also been a major uptick in the volume of cyber-threats targeting home users. With a captive audience to aim at, it’s a huge opportunity for cyber-criminals to steal your log-ins and personal data to sell to fraudsters, or even to steal corporate passwords and information for a potentially bigger pay-off. They are helped by the fact that many home workers may be more distracted than they usually would be at the office, especially if they have young children. Your kids may even share the same laptops or PCs as you, potentially visiting risky sites and/or downloading unapproved apps.

There’s also a chance that, unless you have a corporate machine at home, your personal computing equipment is less secure than the kit you had in the office. Add to that the fact that support from the IT department may be less forthcoming than usual, given that stretched teams are overwhelmed with requests, while themselves struggling to WFH. One recent report claimed that nearly half (47%) of IT security pros have been taken off some or all of their typical security tasks to support other IT-related jobs. In another, only 59% of respondents said they believe their cybersecurity team has the right tools and resources at home to perform their job effectively.

It’s time to step up and take security into your own hands. Stay on the lookout for the following threats.

Unsecured home routers and smart devices might be hijacked in more sophisticated attacks designed to steal data from corporate networks via the home worker. Phishing attacks spoofing well-known brands or using COVID-19 information/news as a lure. Google is blocking 18 million malicious pandemic-themed emails every day. The end goal may be to hijack your online consumer accounts (Netflix, banking, email, online shopping) or work accounts. Other phishing emails are designed to install data-stealing malware, ransomware and other threats. Attackers may target vulnerabilities in your home PCs and the apps you’re using (video conferencing etc) to gain remote access. Business Email Compromise (BEC) attackers may try to leverage the lack of internal communications between remote workers to impersonate senior execs via email, and trick finance team members into wiring corporate funds abroad. Kids exposing home networks and devices to malware on torrent sites, in mobile apps, on social media, and via phishing attacks potentially imitating remote learning/video conferencing platforms. Kids searching for adult/inappropriate content, and/or those that are bored and over-share on social media. Unicef has warned that millions of children are at increased of online harm as lockdown means they spend more of their days online. Mobile apps represent a potential source of malware, especially those found on unofficial app stores. There has also been a reported 51% rise in stalkerware – covert surveillance apps used by domestic abusers and stalkers to target victims. The pandemic has led to a surge in e-commerce fraud where consumers are tricked into buying non-existent products or counterfeit goods including medical items.

So what’s a remote worker/concerned parent to do to protect themselves and the family in the midst of the “new normal?”

Read Part 2 in this mini-series, which we’re publishing simultaneously with Part 1, where we share some best practice advice on how to keep your digital lives and work systems safe from online threats during lockdown—and where we provide tools to help you do just that.

Top Tips For Home Cybersecurity And Privacy In A Coronavirus-Impacted World (Part 2)

The past few months have seen radical changes to our work and home life under the Coronavirus threat, upending norms and confining millions of American families within just four walls. In this context, it’s not surprising that more of us are spending an increasing portion of our lives online. But this brings with it some familiar cyber-risks. In Part 1 of this mini-series, we explained how cyber-criminals are looking to capitalize on these sweeping changes to society to further their own ends.

Now let’s take a look at what you can do to protect your family, your data, and access to your corporate accounts.

How you can stay safe online

The bad guys are laser-focused on stealing your personal data and log-ins and increasingly see the remote worker as an easy target for leapfrogging into corporate networks. That’s not to mention the potential internet safety risks inherent in bored kids spending more time in front of their screens. To respond, you’ll need to create an equally focused “home security plan” governed by sensible policies and best practices. Here are some of the key areas to consider.

Protect your smart home and router

Increasingly, unprotected smart home devices are being targeted by cyber-criminals to turn into botnets to attack others. They might also provide sophisticated attackers with a stepping-stone into your corporate systems, via the home network. The home router, with its known flaws, is (after the modem) the digital front door to the smart home and the basis for your networking, so it should be first in any security strategy. Consider the following when tackling home network security:

Regularly check for router firmware updates and apply as soon as they’re available. (If you’re using a home gateway (modem + router) firmware updates are done by your ISP, so you won’t have the option to do this.) Change factory default admin passwords and switch on two-factor authentication if available. Disable UPnP and any remote management features. Use WPA2 on your router for encrypted Wi-Fi. Pick passwords for access that aren’t easily guessed. Put the router in middle of house if possible, so the signal is not overly exposed to strangers outside. Likewise for extenders. Invest in security for the entire home network from a reputable provider like Trend Micro.

Secure your home office

Cyber-criminals are primed to take advantage of distracted home workers and potentially less secure PCs/devices. Secure this environment by doing the following:

Again, apply a home network security solution. This protects your work devices, while also protecting the devices you use for recreation. Apply any security updates to OS/software. Install/maintain endpoint security software on all machines/devices. Never use work laptops for personal use. Switch on 2FA for any work accounts. Use a VPN if applicable whenever connecting to the office. Stay alert to phishing/BEC attempts. Take advantage of any training courses to stay up-to-speed on the latest scams. Disable macros in Office files – these are often used by hackers to run malware.

Stay safe from phishing

Phishing is the number one tactic used by attackers to trick you into installing malware or handing over your log-ins. Emails, text messages, social media messages and more are spoofed to appear as if sent by a legitimate company or contact. In response:

Be cautious of any unsolicited emails/texts/messages even if they appear legitimate. Don’t click on any links/buttons in unsolicited messages, or download attachments. Check directly with the sender rather than clicking through links or buttons provided or entering any confidential details. Invest in cybersecurity tools from a trusted vendor like Trend Micro, to spot and block scam emails and malicious downloads/websites.

Use video conferencing safely

New videoconferencing platforms can introduce risk, especially if you’re not familiar with the default settings. Here’s how to stay safe when video conferencing:

Check first for end-to-end encryption. Only download videoconferencing apps from official iOS/Android stores and manufacturer websites. Get familiar with privacy settings. Switch off camera access if you don’t want to appear on-screen. Ensure you’re always on the latest software version. Never click on links/open attachments in messages from unknown contacts. Use a password manager to store long and strong log-ins, and switch on two-factor authentication (2FA) if available.

Stay safe shopping and banking

Next, protect your financial information and stay safe from e-commerce fraud by doing the following:

Install AV on all PCs and devices. Always use the latest browser versions and HTTPS sites. Never click through on sensational promos or ads on social media/in emails. Always visit the site directly. Always be cautious: if special offers seem too good to be true, they usually are. Use a secure browser, password manager, and 2FA in your online accounts. Use a VPN app on any device you use to shop or bank.

Think about online safety for kids

They may be under your roof for more hours of the day than usual, but your children are also likely to be spending more time online. That means you need to have a measured conversation with them about internet safety, backed up with parental controls. Consider the following:

Urge your kids to think before clicking, and before sharing on social media. Make sure you have installed anti-malware from a reputable vendor on all their devices. Look for security products that check/update their social media privacy settings. Discourage or block downloads from P2P sites. Set up parental controls to block inappropriate content and/or to regulate screen time and time on certain sites or with certain apps. Then set up admin protections, so they can’t change the settings. Share your concerns around sexting.

Mobile security best practices
Finally, sheltering at home has limits, particularly for restless kids. When they go to the store or out to the park, facemasks notwithstanding, they’re likely going to use their mobile devices, just as they’ll continue to do at home. Of course, you’re not exempt either from mobile threats. Ensure mobile security by

Sticking to the official Google Play and App Store marketplaces. Enforce this through smart settings on your children’s phones. Running anti-malware on your mobile device, from a reputable company like Trend Micro. Ensuring your family’s devices are using the latest OS version. Ensuring your family devices have remote lock and wipe feature switched on, in case they’re lost or stolen. Never brick or jailbreak the device, as this can expose it to security risks.

How Trend Micro can help

When it comes to protecting the home from security and privacy threats during lockdown, leave no stone unturned. Cyber-criminals will always look for the weak link in the chain and focus their efforts there. Network security is important, but it doesn’t replace the need for protection on each individual device. You’ll need to cover your router, network, smart devices, and all endpoints (PCs, laptops, mobiles and other devices). Here’s how Trend Micro can help:
