Crypto-mining is up, Internet of Things (IoT) attacks are on the rise and ransomware is undergoing a “market correction,” according to recent research. As noted by TechRepublic, new data on internet security threats revealed an 8,500 percent jump in the volume of crypto-mining efforts while criminal IoT compromises grew by 600 percent over the previous year.

Ransomware Saturates the Cybercrime Market

According to Security Boulevard, ransomware is now considered a commodity with the rise of cybercrime-as-a-service options, which enable would-be hackers with no technical experience to rent their own versions of popular ransomware.

The increased availability of ransomware tools caused the average ransom fee to drop to $522 in 2017, less than half of what the average cybercriminal demanded in 2016. Still, organizations should expect the sheer number of ransomware attacks leveraging commonly available tools to rise in 2018.

Crypto-Mining Headlines Top Internet Security Threats of 2018

Crypto-mining experienced the largest boost of all internet security threats last year with an 8,500 percent jump, according to Symantec’s “2018 Internet Security Threat Report.” With just a few lines of code, attackers can install crypto-mining software on unsuspecting devices and dig for digital coins in the background.

The lightweight nature of crypto-mining code enables it to fly under the radar of typical threat detection tools even as it consumes central processing unit (CPU) cycles and energy. As more miners are installed on network and IoT devices, performance suffers, energy costs rise and cloud resources are maxed out.

The TechRepublic article likened the rise of crypto-mining to the get-rich-quick lure of 19th century gold rushes and cautioned that new technology designed to combat IoT attacks “will not be enough to stop them all.” Recognizing the telltale signs of a IoT-driven crypto-mining attack, therefore, requires a “well-informed and well-trained workforce.”

Supply Chains in the Crosshairs

As noted in the Symantec report, supply chain attacks are on the rise. These incidents increased by 200 percent in 2017 as cybercriminals looked for ways to compromise valuable corporate systems.

In supply chain attacks, threat actors don’t typically target suppliers directly. Instead, they use them to bypass enterprise network security. For example, NotPetya leveraged flaws in Ukranian accounting software to access larger, more valuable systems.

What’s more, primary targets may not be aware that supply chain partners have been compromised until it’s too late. According to the Security Boulevard piece, companies must ensure that suppliers don’t “walk around cybersecurity controls,” but instead meet all applicable standards.

Zero-Day Exploits Decline as Targeted Attacks Rise

Finally, while zero-day exploits are declining, targeted attacks are on the rise. For example, spear phishing, a technique employed by 71 percent of cybercrime groups last year, is now the top threat vector, according to Symantec. That’s because it works: stealing credentials and bypassing security systems is much easier than fighting with firewalls.

Taking the complexity out of identity solutions for hybrid environments

4 min read - For the past two decades, businesses have been making significant investments to consolidate their identity and access management (IAM) platforms and directories to manage user identities in one place. However, the hybrid nature of the cloud has led many to realize that this ultimate goal is a fantasy. Instead, businesses must learn how to consistently and effectively manage user identities across multiple IAM platforms and directories. As cloud migration and digital transformation accelerate at a dizzying pace, enterprises are left…

IBM identifies zero-day vulnerability in Zyxel NAS devices

12 min read - While investigating CVE-2023-27992, a vulnerability affecting Zyxel network-attached storage (NAS) devices, the IBM X-Force uncovered two new flaws, which when used together, allow for pre-authenticated remote code execution. Zyxel NAS devices are typically used by consumers as cloud storage devices for homes or small to medium-sized businesses. When used together, the flaws X-Force discovered allow a remote attacker to execute arbitrary code on the device with superuser permissions and without requiring any credentials. This results in complete control over the…

What cybersecurity pros can learn from first responders

4 min read - Though they may initially seem very different, there are some compelling similarities between cybersecurity professionals and traditional first responders like police and EMTs. After all, in a world where a cyberattack on critical infrastructure could cause untold damage and harm, cyber responders must be ready for anything. But are they actually prepared? Compared to the readiness of traditional first responders, how do cybersecurity professionals in incident response stand up? Let’s dig deeper into whether the same sense of urgency exists…

Unified endpoint management for purpose-based devices

4 min read - As purpose-built devices become increasingly common, the challenges associated with their unique management and security needs are becoming clear. What are purpose-built devices? Most fall under the category of rugged IoT devices typically used outside of an office environment and which often run on a different operating system than typical office devices. Examples include ruggedized tablets and smartphones, handheld scanners and kiosks. Many different industries are utilizing purpose-built devices, including travel and transportation, retail, warehouse and distribution, manufacturing (including automotive)…
