As we make our move towards a more technologically-advanced way of life where we upload almost everything to our smart devices and cloud storage, the more vulnerable we become to cyberattacks — and yes, even with antivirus programs in place.
This is because cyberattackers adapt to and evolve along with the latest technologies that keep them out of our digital systems. And ever since 2017, they have figured out a way to get into our devices without having us download anything from the internet.
This type of attack comes in the form of fileless threats, a kind of malicious activity wherein legitimate software, applications, and authorized protocols you have on your devices are taken advantage of by cyberattackers — all without the use of malware.
A fileless threat can be set in motion by a user action like clicking on attachments embedded with a code that, when launched, can use the installed applications on a device to carry out malicious system commands.
Once executed, the attack takes place in the Random Access Memory (RAM) where it uses existing system frameworks like Windows Management Instrumentation (WMI) and PowerShell to launch commands that will disrupt your device’s system.
And while the RAM only holds on to data when a device or machine is on, cyberattackers can still target and use other system weaknesses or even use other methods to finish what they have set out to do, like continuing an attack through the configuration of scripts that can start running once the system has been rebooted.
Not all hope is lost though. Global cybersecurity solutions brand Trend Micro tells us all about fileless attacks and provides us with innovative products to help protect our digital machines and devices. Below is an infographic of the characteristics of a fileless threat.
Back in September, during the Security TRENDS 2019 conference, Trend Micro shared that it “has blocked over 26.8 billion fileless threats globally in the first half of 2019,” as stated in its press release — around 91 percent of which were enabled through emails.
Country Manager of Trend Micro Philippines Ian Felipe says that “Sophistication and stealth is the name of the cybersecurity game today,” mentioning how cyberattackers are getting smarter.
According to the mid-year annual roundup report called “Evasive Threats, Pervasive Effects: 2019 Midyear Security Roundup,” cited in the press release, Trend Micro found that businesses are the main targets of fileless attacks. However, it was also emphasized that any kind of setup, even those with protective programs, is still vulnerable to these cyber threats.
That’s why Trend Micro has come up with a line of solutions, both for business and home use, to help shield us from the evolving and clever ways hackers get into our machines and devices.
Maximum Security by Trend Micro has a cloud-based AI Technology that protects against “ever-evolving malware infections” like fileless threats. Detecting and preventing fileless attacks can be tricky, but it’s not impossible.
With Maximum Security, Trend Micro assures users that even “the rapidly changing cyber threat landscape” and ever-adapting cyberattackers are nothing to be afraid of. In fact, you are on to them.
