Online is a little different for everyone

How do you connect online these days? I’ll give you an example from my own life: From my 15-year old son to my 80-year-old mother, not one of us leaves the house without our phone. And today, there isn’t a single thing you can’t do on your phone. It’s the minicomputer that goes where you go. 

This trend in the way we connect is reflected in recent data too. In fact, we’ve found that the average consumer spends 6 hours and 55 min online per day, split between mobile (52%) and desktop (48%). Whether you’re a Boomer, Gen X, a Millennial, or Gen Z, the way you connect online is diverse and specific to you. 

As for what we’re doing online? It’s just about everything. After all, we spend an average of 7 hours per day on connected devices and the pandemic has forced us to do even more online. The downside to this rapid change in the way we live is that we are opening ourselves up to more risk which leaves consumers feeling highly concerned about their ability to keep their personal info secure or private. We need new protection for this new normal. 

For the new normal, a new approach to protection with mobile security 

What all these changes mean is that you’re able to have the same online experience regardless of where you are, what you’re doing, or what device you’re using. Your favorite streaming service is a great example – you can just as easily find a movie on a tablet as you can on your laptop. In fact, you can pause the movie you’re watching on that tablet and pick up where you left off on your laptop. Your experience with online security should offer the same convenience and familiarity. More importantly, online protection should give you a feeling of confidence however or wherever you choose to connect. 

 This means knowing your personal info is secure even when accessing an unsecured network, your browsing habits remain private, and you can take necessary actions should your information be compromised. To put it another way, YOU are what we’re focused on protecting and we do that by making sure everything you connect with is also secure. 

Introducing the new McAfee Security mobile app 

A phone is the remote control for your life. From the palm of your hand, you’re able to shop, browse, stream, and create – everything you do online you can now do from your phone. So, it’s crucial that your phone be a major focus of our online protection. The new mobile app makes it easier to get robust protection for your identity, privacy, and phone. Let’s look at a few of the capabilities offered by the new mobile app. 

Identity Protection Service

Think about all the online accounts you’ve created in the past year. How many of them do you use regularly? Sometimes I think I have more food delivery apps on my phone than I do restaurants to use them on. Regardless of how often you use an account (or if you no longer use it at all!), any personal information (like emails, addresses, credit cards) added to it is available online and vulnerable to breaches. McAfee Security comes with identity protection, a feature that monitors your personal information and then notifies you when there’s a risk of your data being compromised. What this means is that if we detect that your data was stolen, you’ll be alerted an average of 10 months earlier than similar services, so you can act before your data is used illegally or shows up on the dark web. 

Privacy protection with Secure VPN

Let’s say you’re about to use the free internet at your favorite café for a speedier connection. Time to flip on your virtual private network (VPN). Forget about digging through a sea of menus to find your VPN. The new mobile app offers a seamless VPN experience so you can keep your activity hidden on less-than-secure Wi-Fi. Or, better yet, you can set up a Secure VPN to automatically turn on for unsecured Wi-Fi networks. Whatever you choose, Secure VPN keeps your personal data and location private anywhere you go with unlimited data and bank-grade Wi-Fi encryption. 

Device protection 

At the end of the day, phones are devices and they’re vulnerable to viruses, malware, and, increasingly, malicious apps. The new McAfee Mobile app offers an antivirus scan for Android phones and system scans to see if your passcode is strong enough and that your OS is up to date on iOS devices. 

Most importantly, the app is part of McAfee’s total online protection, so the experience on your phone is the same as on your PC. It’s protection that goes where you go – at home on your PC, or on the go with your mobile. 

The mobile app is available right now – here’s how to get it 

If you’re an existing McAfee subscriber using McAfee Total Protection or McAfee LiveSafe, you can get the app right now. And, if you’ve already got the app installed, just make sure it’s up-to-date and you’ll be all set with the new look and features. 

Interested in trying the app out? You can buy or get a free trial of McAfee Total Protection here and get started today.

You consider yourself a responsible person when it comes to taking care of your physical possessions. You’ve never left your wallet in a taxi or lost an expensive ring down the drain. You never let your smartphone out of your sight, yet one day you notice it’s acting oddly.  

Did you know that your device can fall into cybercriminals’ hands without ever leaving yours? SIM swapping is a method that allows criminals to take control of your smartphone and break into your online accounts. 

Don’t worry: there are a few easy steps you can take to safeguard your smartphone from prying eyes and get back to using your devices confidently. 

What Is a SIM Card? 

First off, what exactly is a SIM card? SIM stands for subscriber identity module, and it is a memory chip that makes your phone truly yours. It stores your phone plan and phone number, as well as all your photos, texts, contacts, and apps. In most cases, you can pop your SIM card out of an old phone and into a new one to transfer your photos, apps, etc. 

What Is SIM Swapping? 

Unlike what the name suggests, SIM swapping doesn’t require a cybercriminal to get access to your physical phone and steal your SIM card. SIM swapping can happen remotely. A cybercriminal, with a few important details about your life in hand, can answer security questions correctly, impersonate you, and convince your mobile carrier to reassign your phone number to a new SIM card. At that point, the criminal can get access to your phone’s data and start changing your account passwords to lock you out of your online banking profile, email, and more. 

SIM swapping was especially relevant right after the T-Mobile data breach.1 Cybercriminals stole millions of phone numbers and the users’ associated personal details. Criminals could later use these details to SIM swap, allowing them to receive users’ text or email two-factor authentication codes and gain access to their personal accounts. 

How Can You Tell If You’ve Been SIM Swapped? 

The most glaring sign that your phone number was reassigned to a new SIM card is that your current phone no longer connects to the cell network. That means you won’t be able to make calls, send texts, or surf the internet when you’re not connected to Wi-Fi. Since most people use their smartphones every day, you’ll likely find out quickly that your phone isn’t functioning as it should.  

Additionally, when a SIM card is no longer active, the carrier will often send a notification text. If you receive one of these texts but didn’t deactivate your SIM card, use someone else’s phone or landline to contact your wireless provider. 

How to Prevent SIM Swapping 

Check out these tips to keep your device and personal information safe from SIM swapping.  

1. Set up two-factor authentication using authentication apps. Two-factor authentication is always a great idea; however, in the case of SIM swapping, the most secure way to access authentication codes is through authentication apps, versus emailed or texted codes. It’s also a great idea to add additional security measures to authentication apps, such as protecting them with a PIN code, fingerprint, or face ID. Choose pin codes that are not associated with birthdays, anniversaries, or addresses. Opt for a random assortment of numbers.  
2. Watch out for phishing attempts. Cybercriminals often gain fodder for their identity-thieving attempts through phishing. Phishing is a method cyber criminals use to fish for sensitive personal information that they can use to impersonate you or gain access to your financial accounts. Phishing emails, texts, and phone calls often use fear, excitement, or urgency to trick people into giving up valuable details, such as Social Insurance Numbers, birthdays, passwords, and PINs. Be wary of messages from people and organizations you don’t know. Even if the sender looks familiar, there could be typos in the sender’s name, logo, and throughout the message that are a good tipoff that you should delete the message immediately. Never click on links in suspicious messages. 
3. Use a password manager. Your internet browser likely asks you if you’d like the sites you visit to remember your password. Always say no! While password best practices can make it difficult to remember all your unique, long, and complex passwords and passphrases, do not set up autofill as a shortcut. Instead, entrust your passwords and phrases to a secure password manager, such as True Key. A secure password manager makes it so you only have to remember one password. The rest of them are encrypted and protected by two-factor authentication. A password manager makes it very difficult for a cybercriminal to gain entry to your accounts, thus keeping them safe. 

Boost Your Smartphone Confidence 

With just a few simple steps, you can feel better about the security of your smartphone, cellphone number, and online accounts. If you’d like extra peace of mind, consider signing up for an identity theft protection service like McAfee Identity Protection Service. McAfee, on average, detects suspicious activity ten months earlier than similar monitoring services. Time is of the essence in cases of SIM swapping and other identity theft schemes. An identity protection partner can restore your confidence in your online activities.

Your Cybersecurity Comic Relief 

CVE-2021-20322: Of all the words of mice and men, the saddest are, “it was DNS again.” 

Why am I here? 

For all our newcomers, welcome to the Advanced Threat Research team’s monthly bug report – a digest of all the latest and greatest vulnerabilities from the last 30-ish days based on merits just a tad more nuanced than sorting NVD by “CVSS > 9.0.” Instead, we focus on qualitative and experience-based analysis, relying on over 100 years of combined industry experience within our team. 

To those who are returning after having read last month’s issue, I would like to congratulate you for being a Bug Report fan before it was cool – which it now most assuredly is, thanks in no small part to a litany of fascinating vulnerabilities. We encourage our veterans to stick around as long as possible, so that a year from now you can complain about how we’re washed up and how much better our early editions were. 

PAN GlobalProtect VPN: CVE-2021-3064 

What is it? 

Palo Alto Networks (PAN) firewalls that use its GlobalProtect Portal VPN running PAN-OS versions older than 8.1.17 are vulnerable to a cutting-edge, state-of-the-art style of vulnerability known as a “stack-based buffer overflow.” Although the vulnerable code is normally not reachable, when combined with an HTTP smuggling vulnerability, CVE-2021-3064 can be used to gain remote code execution, a remote shell, and even access to sensitive configuration data according to Randori Attack Team researchers. Randori discovered the vulnerability over a year ago but chose not to disclose it to PAN until September of this year, using it as part of its “continuous and automated red team platform” during the interim – I suppose we should be thankful that PAN has claimed in its security advisory that no evidence of exploitation of this vuln has been discovered, despite its age. 

Who cares? 

Absence of “in-the-wild” exploitation aside, we should also be grateful that the number of people who should care is rapidly dwindling (an ever-present theme of 2021). Randori initially reported over 70,000 internet-accessible PAN firewalls running vulnerable versions of PAN-OS according to Shodan, which it later amended to 10,000. As of this writing, that number has fallen to around 7,000. Even so, 7,000 vulnerable firewalls mean an even larger number of vulnerable clients at risk of an over-the-internet attack vector requiring zero authentication. Those connecting to PAN firewalls running on VMs have even greater cause for concern as these lack ASLR, a factoid I have chosen to add to my ever-growing “why is that a thing” list, right next to the Ghostbusters remake. 

What can I do? 

We suggest an experiment: open the Shodan search linked above and note the total number of devices running a vulnerable version of PAN-OS. Next, call up whoever manages your firewall and demand they power it down immediately – use threats if you must. Check the Shodan scan again: has the number gone down? If so, it’s probably time to update. If you’re an Arch user and the prospect of updating terrifies you, Palo Alto has also indicated that its signatures for Unique Threat IDs 91820 and 91855 should block exploitation of CVE-2021-3064. 

The Gold Standard 

Be sure to stay up to date on the latest CVEs – our security bulletins are a great resource for finding product information for all kinds of critical vulnerabilities. 

Linux Kernel: CVE-2021-20322 

What is it? 

Researchers at the University of California, Riverside have discovered a flaw in the way the Linux kernel handles “ICMP fragment needed” and “ICMP redirect” errors, allowing an attacker to quickly learn the randomized port number assigned to a UDP socket. What this description fails to convey is the big picture impact of this vulnerability, which is its use as a side-channel for the now-prehistoric DNS cache poisoning attack, in which an off-path malicious actor ‘poisons’ a DNS resolver’s cache with a false record, mapping a known domain (google.com) to an IP address of their choosing (98.136.144.138). Truly nefarious. 

Who cares? 

To be frank, just about everyone should be at least raising an eyebrow at this one. Although the researchers have indicated in their whitepaper that this particular side-channel only affects about 13.85% of open resolvers on the internet, it’s important to note that various security services rely on proof of domain ownership, including even the issuing of certificates, making the impact tremendous. Users of popular DNS service Quad9 have particular cause for concern, as the paper claims it falls under the vulnerable 13.85%. Linux users should also be concerned, and not just because their drivers refuse to work – DNS software such as BIND, Unbound, and dnsmasq running on their platform of choice are also vulnerable. 

What can I do? 

This is where things get tricky. DNS extensions that were standardized over two decades ago, such as DNSSEC and DNS cookies, should successfully mitigate this and all other DNS cache poisoning attack side channels. The unfortunate reality is that these features see very limited adoption due to backwards-compatibility concerns. While we wait for these dinosaurs holding back progress to die out, the authors of the aforementioned whitepaper have suggested some alternative mitigations, including enabling the IP_PMTUDISC_OMIT socket option, introducing additional randomization to the structure of the DNS exception cache, and configuring DNS servers with a singular default gateway to outright reject ICMP redirects. Further details can be found in section 8.4 of their paper. 

The Gold Standard 

Unfortunately, not every vulnerability can be adequately addressed by network security products, and this vulnerability happens to be one of those cases. Your best bet is to follow the mitigations mentioned above and keep your servers up to date. 

Just About All DRAM: CVE-2021-42114 aka Blacksmith 

What is it? 

Blacksmith, a name referring to both the vulnerability and the fuzzer created to exercise it, is a new implementation of the Rowhammer DRAM hardware vulnerability from 2014. The crux of Rowhammer is the use of high frequency read operations to induce bit flips in neighboring regions of physical memory, which can lead to the crossing of any security barrier if the attacker can massage memory so that critical data is stored in a vulnerable physical page. Modern DRAM hardware uses a technology called Target Row Refresh (TRR) to prematurely refresh regions of physical memory targeted by common Rowhammer attacks. Researchers at ETH Zurich and their associates discovered that TRR exploits the uniform nature of memory accesses used by existing Rowhammer attacks to “catch” them, and so devised a Rowhammer attack that used non-uniform accesses, arriving at CVE-2021-42114, which bypasses TRR and all other modern Rowhammer mitigations. 

Who cares? 

Everyone. Just about every common electronic device you can think of uses DRAM and of the DIMMs (RAM sticks) tested, the researchers did not find a single one that was completely safe. It might be easy to presume that hardware vulnerabilities such as this are academically fascinating but have little real-world impact, but research published since 2014 has shown Rowhammer attacks successfully escape JavaScript containers in the browser, cross VM boundaries in the cloud, and even achieve RCE across networks with high enough throughput. Perhaps the greatest tragedy of Blacksmith is that it arrived a month too late – it would have fit in perfectly with Halloween monsters like Freddy Krueger or Jason Voorhees who also see new iterations every few years and refuse to stay dead. 

What can I do? 

Hide your PC, hide your tablet, and hide your phone, ‘cause they’re hammerin’ everybody out there. Beyond that, there’s not much to be done besides wait for JEDEC to develop a fix and for DRAM manufacturers to begin supplying hardware with the new standard. 

The Gold Standard 

We at McAfee Enterprise are doing everything in our power to address this critical vulnerability. In other words, we’ll be waiting for that JEDEC fix right along with you.
