- Know the Symptoms: Protect Your Devices While Working From Home
The coronavirus pandemic has forced most businesses to accommodate work-from-home (WFH) arrangements, but organizations that were unprepared for the shift to remote operations may have been left scrambling. This may have resulted in unsecured systems left running in the office or vulnerable hardware that employees took home.
Threat actors are aware of this situation, and they’re capitalizing on it: Trend Micro has detected an increase in attack attempts and malicious routines targeting remote systems and connected devices. The attacks on remote and home devices from December 2019 to the end of the first quarter of 2020 shows a significant increase compared to the activity detected within the same period the previous year.

Cybercriminals have been employing known techniques and attacking common entry points to get into users’ home networks and devices. From exhausting default passwords and revisiting unpatched vulnerabilities, to scanning for open ports and services and installing backdoors, these malicious actors have noticeably increased their deployments over the last four months.

As more news related to the pandemic came in, malicious routines targeting or luring users with coronavirus-related messages also increased as more professionals became dependent on their home networks and devices to accomplish their tasks. And while not all intrusions, malicious routines, and attacks have observable signs, there are telltale symptoms that non-technical employees can check to determine if their devices have been hacked or infected with malware.
Some malicious routines don’t exhibit any obvious signs of infection or intrusion, while some symptoms become evident after specific user actions. But while these are not encompassing signs of a possible infection or attack, these are the common and observable signs of malware infection and intrusion.
Cybercriminals constantly change or improve their techniques for infecting and attacking a growing array of mobile and smart devices. Here are the possible ways they can get through:
Overnight remote work schemes that the coronavirus pandemic has caused may be overwhelming to the current infrastructure, but every business should regard it as the new norm. These new business continuity procedures have increased the use of personal equipment and work devices connected to home networks, and this could lead to issues considering the possibly lower security measures at home compared to the workplace. As such, short term solutions focused on output delivery may have to be changed for long-term and sustainable business solutions. More than ever, users have to secure data access between their homes and the office.
Trend Micro continues to monitor all attacks and malicious routines related to Covid-19 that can compromise your businesses and devices. Multilayered protection is also recommended for protecting all fronts and preventing users from accessing malicious domains that could deliver malware. Trend Micro endpoint solutions such as the Smart Protection Suites and Worry-Free™ Business Security detect and block malware as well as and the malicious domains they use.
As an added layer of defense, Trend Micro™ Email Security thwarts spam and other email attacks. The protection it provides is constantly updated, protecting the system from both old and new attacks. Trend Micro™ InterScan™ Messaging Security provides comprehensive protection that stops inbound threats and secures outbound data, as well as blocks spam and other email threats.
Users can employ comprehensive protections such as the Trend Micro™ Security and Trend Micro™ Internet Security solutions, which offer effective safeguards against threats to IoT devices through features that can detect malware at the endpoint level. Connected devices can also be protected by security software such as the Trend Micro™ Home Network Security and Trend Micro Smart Home Network™ (SHN) solutions, which can check internet traffic between the router and all connected devices. The Trend Micro™ Deep Discovery™ Inspector network appliance can monitor all ports and network protocols for advanced threats and protect enterprises from targeted attacks.
