Ransom from Home – How to close the cyber front door to remote working ransomware attacks

Coronavirus has caused a major shift to our working patterns. In many cases these will long outlast the pandemic. But working from home has its own risks. One is that you may invite ransomware attacks from a new breed of cyber-criminal who has previously confined his efforts to directly targeting the corporate network. Why? Because as a remote worker, you’re increasingly viewed as a soft target—the open doorway to extorting money from your employer.

So how does ransomware land up on your front doorstep? And what can a home worker do to shut that door?

The new ransomware trends

Last year, Trend Micro detected over 61 million ransomware-related threats, a 10% increase from 2018 figures. But things have only gotten worse from there. There has been a 20% spike in ransomware detections globally in the first half of 2020, rising to 109% in the US. And why is that?

At a basic level, ransomware searches for and encrypts most of the files on a targeted computer, so as to make them unusable. Victims are then asked to pay a ransom within a set time frame in order to receive the decryption key they need to unlock their data. If they don’t, and they haven’t backed-up this data, it could be lost forever.

The trend of late, however, has been to focus on public and private sector organizations whose staff are working from home (WFH). The rationale is that remote workers are less likely to be able to defend themselves from ransomware attacks, while they also provide a useful stepping-stone into high-value corporate networks. Moreover, cybercriminals are increasingly looking to steal sensitive data before they encrypt it, even as they’re more likely to fetch a higher ransom for their efforts than they do from a typical consumer, especially if the remote employee’s data is covered by cyber-insurance.

Home workers are also being more targeted for a number of reasons:

They may be more distracted than those in the office. Home network and endpoint security may not be up to company levels. Home systems (routers, smart home devices, PCs, etc.,) may not be up-to-date and therefore are more easily exposed to exploits. Remote workers are more likely to visit insecure sites, download risky apps, or share machines/networks with those who do. Corporate IT security teams may be overwhelmed with other tasks and unable to provide prompt support to a remote worker. Security awareness programs may have been lacking in the past, perpetuating bad practice for workers at home.

What’s the attack profile of the remote working threat?

In short, the bad guys are now looking to gain entry to the corporate network you may be accessing from home via a VPN, or to the cloud-hosted systems you use for work or sharing files, in order to first steal and then encrypt company data with ransomware as far and wide as possible into your organization. But the methods are familiar. They’ll

Try to trick you into dangerous behavior through email phishing—the usual strategy of getting you to click links that redirect you to bad websites that house malware, or getting you to download a bad file, to start the infection process. Steal or guess your log-ins to work email accounts, remote desktop tools (i.e., Microsoft Remote Desktop or RDP), and cloud-based storage/networks, etc., before they deliver the full ransomware payload. This may happen via a phishing email spoofed to appear as if sent from a legitimate source, or they may scan for your use of specific tools and then try to guess the password (known as brute forcing). One new Mac ransomware, called EvilQuest, has a keylogger built into it, which could capture your company passwords as you type them in. It’s a one-two punch: steal the data first, then encrypt it. Target malware at your VPN or remote desktop software, if it’s vulnerable. Phishing is again a popular way to do this, or they may hide it in software on torrent sites or in app stores. This gives them a foothold into your employer’s systems and network. Target smart home devices/routers via vulnerabilities or their easy-to-guess/crack passwords, in order to use home networks as a stepping-stone into your corporate network.

How can I prevent ransomware when working from home?

The good news is that you, the remote worker, can take some relatively straightforward steps up front to help mitigate the cascading risks to your company posed by the new ransomware. Try the following:

Be cautious of phishing emails. Take advantage of company training and awareness courses if offered. Keep your home router firmware, PCs, Macs, mobile devices, software, browsers and operating systems up to date on the latest versions – including remote access tools and VPNs (your IT department may do some of this remotely). Ensure your home network, PCs, and mobile devices are protected with up-to-date with network and endpoint AV from a reputable vendor. (The solutions should include anti-intrusion, anti-web threat, anti-spam, anti-phishing, and of course, anti-ransomware features.) Ensure remote access tools and user accounts are protected with multi-factor authentication (MFA) if used and disable remote access to your home router. Disable Microsoft macros where possible. They’re a typical attack vector. Back-up important files regularly, according to 3-2-1 rule.

How Trend Micro can help

In short, to close the cyber front door to ransomware, you need to protect your home network and all your endpoints (laptops, PCs, mobile devices) to be safe. Trend Micro can help via

From Bugs to Zoombombing: How to Stay Safe in Online Meetings

The COVID-19 pandemic, along with social distancing, has done many things to alter our lives. But in one respect it has merely accelerated a process begun many years ago. We were all spending more and more time online before the virus struck. But now, forced to work, study and socialize at home, the online digital world has become absolutely essential to our communications — and video conferencing apps have become our “face-to-face” window on the world.

The problem is that as users flock to these services, the bad guys are also lying in wait — to disrupt or eavesdrop on our chats, spread malware, and steal our data. Zoom’s problems have perhaps been the most widely publicized, because of its quickly rising popularity, but it’s not the only platform whose users have been potentially at risk. Cisco’s WebEx and Microsoft Teams have also had issues; while other platforms, such as Houseparty, are intrinsically less secure (almost by design for their target audience, as the name suggests).

Let’s take a look at some of the key threats out there and how you can stay safe while video conferencing.

What are the risks?

Depending on the platform (designed for work or play) and the use case (business or personal), there are various opportunities for the online attacker to join and disrupt or eavesdrop on video conferencing calls. The latter is especially dangerous if you’re discussing sensitive business information.

Malicious hackers may also look to deliver malware via chats or shared files to take control of your computer, or to steal your passwords and sensitive personal and financial information. In a business context, they could even try to hijack your video conferencing account to impersonate you, in a bid to steal info from or defraud your colleagues or company.

The bad guys may also be able to take advantage of the fact that your home PCs and devices are less well-secured than those at work or school—and that you may be more distracted at home and less alert to potential threats.

To accomplish their goals, malicious hackers can leverage various techniques at their disposal. These can include:

Exploiting vulnerabilities in the video conferencing software, particularly when it hasn’t been updated to fend off the latest threats Stealing your log-ins/meeting ID via malware or phishing attacks; or by obtaining a meeting ID or password shared on social media Hiding malware in legitimate-looking video apps, links and files Theft of sensitive data from meeting recordings stored locally or in the cloud.

Zooming in on trouble

Zoom has in many ways become the victim of its own success. With daily meeting participants soaring from 10 million in December last year to 200 million by March 2020, all eyes have been focused on the platform. Unfortunately, that also includes hackers. Zoom has been hit by a number of security and privacy issues over the past several months, which include “Zoombombing” (meetings disrupted by uninvited guests), misleading encryption claims, a waiting room vulnerability, credential theft and data collection leaks, and fake Zoom installers. To be fair to Zoom, it has responded quickly to these issues, realigning its development priorities to fix the security and privacy issues discovered by its intensive use.

And Zoom isn’t alone. Earlier in the year, Cisco Systems had its own problem with WebEx, its widely-used enterprise video conferencing system, when it discovered a flaw in the platform that could allow a remote, unauthenticated attacker to enter a password-protected video conferencing meeting. All an attacker needed was the meeting ID and a WebEx mobile app for iOS or Android, and they could have barged in on a meeting, no authentication necessary. Cisco quickly moved to fix the high-severity vulnerability, but other flaws (also now fixed) have cropped up in WebEx’s history, including one that could enable a remote attacker to send a forged request to the system’s server.

More recently, Microsoft Teams joined the ranks of leading business videoconferencing platforms with potentially deadly vulnerabilities. On April 27 it surfaced that for at least three weeks (from the end of February till the middle of March), a malicious GIF could have stolen user data from Teams accounts, possibly across an entire company. The vulnerability was patched on April 20—but it’s a reminder to potential video conferencing users that even leading systems such as Zoom, WebEx, and Teams aren’t fool-proof and require periodic vulnerability and security fixes to keep them safe and secure. This is compounded during the COVID-19 pandemic when workers are working from home and connecting to their company’s network and systems via possibly unsecure home networks and devices.

Video conferencing alternatives

So how do you choose the best, most secure, video conferencing software for your work-at-home needs? There are many solutions on the market today. In fact, the choice can be dizzying. Some simply enable video or audio meetings/calls, while others also allow for sharing and saving of documents and notes. Some are only appropriate for one-on-one connections or small groups, while others can scale to thousands.

In short, you’ll need to choose the video conferencing solution most appropriate to your needs, while checking if it meets a minimum set of security standards for working at home. This set of criteria should include end-to-end encryption, automatic and frequent security updates, the use of auto-generated meeting IDs and strong access controls, a program for managing vulnerabilities, and last but not least, good privacy practices by the company.

Some video conferencing options alongside Zoom, WebEx, and Teams include:

Signal which is end-to-end encrypted and highly secure, but only supports one-to-one calls. FaceTime, Apple’s video chat tool, is easy-to-use and end-to-end encrypted, but is only available to Mac and iOS users. Jitsi Meet is a free, open-source video conferencing app that works on Android, iOS, and desktop devices, with no limit on participants beyond your bandwidth. Skype Meet Now is Microsoft’s free, popular conferencing tool for up to 50 users that can be used without an account, (in contrast to Teams, which is a paid, more business-focused platform for Office 365 users). Google Duo is a free option for video calls only, while the firm’s Hangouts platform can also be used for messaging. Hangouts Meet is a more business-focused paid version. Doxy.me is a well-known telemedicine platform used by doctors and therapists that works through your browser—so it’s up to you to keep your browser updated and to ensure the appropriate security and privacy settings are in place. Secure medical consultation with your healthcare provider is of particular concern during the shelter- and work-from-home quarantine.

How do I stay safe?

Whatever video conferencing platform you use, it’s important to bear in mind that cyber-criminals will always be looking to take advantage of any security gaps they can find — in the tool itself or your use of it. So how do you secure your video conferencing apps? Some tips listed here are Zoom-specific, but consider their equivalents in other platforms as general best-practice tips. Depending on the use case, you might choose to not enable some of the options here.

Check for end-to-end encryption before getting onboard with the app. This includes encryption for data at rest. Ensure that you generate one-off meeting IDs and passwords automatically for recurring meetings (Zoom). Don’t share any meeting IDs online. Use the “waiting room” feature in Zoom (now fixed), so the host can only allow attendees from a pre-assigned list. Lock the meeting once it’s started to stop anyone new from joining. Allow the host to put attendees on hold, temporarily removing them from a meeting if necessary. Play a sound when someone enters or leaves the room. Set screen-sharing to “host only” to stop uninvited guests from sharing disruptive content. Disable “file transfers” to block possible malware. Keep your systems patched and up-to-date so there are no bugs that hackers can target. Only download conferencing apps from official iOS/Android stores and manufacturer websites. Never click on links or open attachments in unsolicited mail. Check the settings in your video conferencing account. Switch off camera access if you don’t want to appear on-screen. Use a password manager for video conferencing app log-ins. Enhance passwords with two-factor authentication (2FA) or Single-Sign-On (SSO) to protect access, if available. Install anti-malware software from a reputable vendor on all devices and PCs. And implement a network security solution if you can.

How Trend Micro can help

Fortunately, Trend Micro has a range of capabilities that can support your efforts to stay safe while using video conferencing services.

Trend Micro Home Network Security (HNS) protects every device in your home connected to the internet. That means it will protect you from malicious links and attachments in phishing emails spoofed to appear as if sent from video conferencing firms, as well as from those sent by hackers that may have covertly entered a meeting. Its Vulnerability Check can identify any vulnerabilities in your home devices and PCs, including work laptops, and its Remote Access Protection can reduce the risk of tech support scams and unwanted remote connections to your device. Finally, it allows parents to control their kids’ usage of video conferencing applications, to limit their exposure.

Trend Micro Security also offers protection against email, file, and web threats on your devices. Note too, that Password Manager is automatically installed with Maximum Security to help users create unique, strong passwords for each application/website they use, including video conferencing sites.

Finally, Trend Micro WiFi Protection (multi-platform) / VPN Proxy One (Mac and iOS) offer VPN connections from your home to the internet, creating secure encrypted tunnels for traffic to flow down. The VPN apps work on both Wi-Fi and Ethernet connections. This could be useful for users concerned their video conferencing app isn’t end-to-end encrypted, or for those wishing to protect their identity and personal information when interacting on these apps.

COVID-19: How Do I Work from Home Securely?

The coronavirus pandemic—the infection officially designated as COVID-19—is causing upheaval across the globe. Aside from the serious economic and public health implications, one very practical impact of shelter-in-place dictums is to force many companies to support remote working where they can. The most recent data tells us that in 2017, eight million Americans worked from home at least some of the week — amounting to around 5% of US workers. However, the events of the past few weeks are driving what is being described in certain sectors as the biggest shift to home working since 9/11.

This will ensure that many companies can continue functioning while helping to achieve social distancing to minimise the spread of the virus. But there are challenges, particularly to smaller businesses who don’t have IT security teams to assist with the transition. Hackers are primed and ready to take advantage of home workers, whose machines and devices may not be as secure as those in the office. There’s also a risk that workers are more distracted by current events when working at home, creating more opportunities for cyber-criminals to strike.

This isn’t just about hackers stealing your personal log-ins and information to sell on the dark web. In a home-working context, corporate data and systems may also be at risk. It takes just one unsecured remote worker to let the bad guys in. The damage they end up doing may be particularly difficult for employers to weather given the extreme economic pressures already on many firms.

With that in mind, therefore, let’s take a look at some of the major threats to home workers and their organizations, and what can be done to keep the hackers at bay.

The main threats

Phishing messages are by far the number one threat to home workers. Cyber-criminals are using widespread awareness of COVID-19, and a desire for more information on the outbreak, to trick users into clicking on malicious links or opening booby-trapped attachments. Many are spoofed to appear as if sent by trusted organizations such as the US Centers for Disease Control and Prevention (CDC) or the World Health Organization (WHO). They may claim to offer more information on the spread of the outbreak, tips on staying safe, and even provide details of how to get a non-existent vaccine online.

If you click through on a malicious link, the next stage of the attack could:

Take you to a convincing-looking log-in page (e.g., for Microsoft Outlook, Office 365, or any popular cloud apps) where your username and password could be harvested by hackers. With these, they have a foothold in the organization which could provide the foundation for a serious information-stealing attack. Covertly initiate a malware download. This malware could exploit unpatched vulnerabilities on your computer to infect not just your machine but the entire corporate network it’s connected to, with ransomware, cryptojacking malware, banking trojans, information-stealing threats, and much more.

Brute forcing is another way for hackers to hijack your cloud accounts. They use previously breached username/password combos and run them through automation software to try them across billions of websites and apps. Because users reuse passwords across numerous accounts, the bad guys often get lucky and are able to unlock additional accounts in this way. Home workers using Microsoft Teams, Slack, Zoom and other cloud platforms for collaboration and productivity may be targeted.

Malicious smartphone apps are another threat to home workers. These may be disguised to trick the user into believing they’re downloading a COVID-19 tracker, for example. In reality, it could infect the device with ransomware, info-stealers, or other malware. That device could then spread the same malware to the corporate network, if it is connected to it via the home network.

Smart device threats are also a concern for home workers. More and more of us are investing in smart home devices. From voice assistants to smart speakers, connected refrigerators to smart TVs, it’s estimated that there’ll be as many as 128 million smart homes in the US by the end of this year. However, often these consumer-grade devices don’t have strong built-in protection. They may use weak, factory default passwords and/or contain multiple software vulnerabilities which are rarely patched by the manufacturer, if at all. The risk is that hackers could hijack one or more of these devices and use them as a stepping stone into the home and then corporate network – as we’ve demonstrated in previous research.

Friends and family could also introduce new cyber-threats, as they will also be confined largely to the home. That means they’ll be logging on to the home network with their own mobile devices, which may not be as well protected from threats as they should be. Once again, such threats could spread quickly from the home network to infect the enterprise network if it’s connected without adequate security controls. Another risk is of children using unsecured remote learning platforms, which may offer cybercriminals opportunities to hijack accounts, steal information and spread malware onto the network.

What are the hackers after?

Home workers represent an attractive target in their own right. After all, personal information and log-ins (home banking, Netflix, webmail etc) can be easily sold for a profit on dark web marketplaces. However, organizations represent a much bigger, potentially more lucrative pay day for cyber-criminals. While corporate PCs and networks might be fairly well secured, the rush to support home working may have left gaps the bad guys are keen to exploit.

By first compromising the home worker, and then pivoting through unsecured channels to the corporate network, hackers could spread ransomware, steal sensitive company IPs, infect work networks with crypto-mining malware, or steal large volumes of customer data. They may also look to hijack employees’ corporate email or other accounts as the first part of a multi-stage information-stealing attack. There have even been new warnings of Business Email Compromise (BEC) attacks in which employees (usually those working in the finance department) are contacted by someone posing as a senior exec and ordered to wire business funds to a new bank account.

Working safely at home

With so many techniques at their disposal, it’s easy to imagine that the bad guys have the upper hand. But by putting a few best practices in place, there are things businesses and employees can do today to reduce home working security risks.

Consider the following:

User awareness exercises to improve the ability of home workers to spot phishing attacks. Ensure all home workers are outfitted with anti-malware for any devices used for work. Trend Micro Maximum Security is an excellent place to start for PCs and Macs, while Trend Micro Mobile Security can help secure Android and Mobile devices. Require strong, unique passwords for all accounts, stored in a password manager, such as Trend Micro Password Manager. Enhance the above by switching on two-factor authentication for all enterprise accounts that have it (including any cloud platforms). Always use a VPN for communication between home and corporate networks. Ensure staff have a clear route to report any security incidents. Switch on automatic updates for all home computer systems (operating systems and software). Ensure smart home devices are on latest software version and have strong passwords or 2FA. Use a network security solution like Trend Micro Home Network Security to secure your home network. It not only provides a secure baseline for working at home, with its web and content threat protections; you can block your kids’ use of the internet and YouTube while you’re having conference calls or doing other bandwidth-intensive work on the remotely-accessed corporate network. Tightly enforce endpoint security policies: if possible, only allow work devices to connect to the corporate network, and/or employee devices that have been previously scanned for threats.

We don’t know how long COVID-19 will last. But by adapting to the new reality as quickly as possible, businesses and their home workers can at least close down any security gaps, enabling them to be as productive as possible — while most importantly, staying safe and healthy.
