Use of malware, botnets and exploits expands

Issue 3 2022 News & Events

Nuspire, a managed security services provider (MSSP), has announced the release of its Q1 2022 Threat Report. The report outlines new cybercriminal activity and tactics, techniques and procedures (TTPs), as well as provides data and insight into malware, exploit and botnet activity.

Nuspire’s data revealed a significant number of new vulnerabilities leading to increases in threat actor activity across all three of the threat classifications it studies: malware, botnets and exploits. Of note are several older botnets that saw a resurgence in Q1, including Mirai, STRRAT and Emotet.

Mirai, known for co-opting IoT devices to launch DDoS attacks, showed a spike in activity in February 2022 (https://en.wikipedia.org/wiki/Mirai_(malware)). This corresponded with the discovery of Spring4Shell, a zero-day attack on popular Java web application framework, Spring Core. The attack allows for unauthenticated remote code execution and data shows Mirai exploited this vulnerability to its botnet.

STRATT botnet, which engages in information stealing, keystroke logging and credential harvesting from browsers and email clients, also spiked in February. This data corresponds with recent announcements identifying a new STRRAT phishing campaign.

“With Q4 2021 being a quieter quarter for cyberattacks we predicted Q1 2022 would see a rebound and our data proves that,” said J.R. Cunningham, chief security officer at Nuspire. “As zero-day attacks and numerous other vulnerabilities among big-name companies like Google and Microsoft come to light, threat actors are quickly adjusting their tactics and these exploits tend to get industry attention, but the threat posed by older and well-understood attacks still persists. It’s critical businesses of all sizes understand the costliness of these attacks and fortify their security posture accordingly.”

Additional notable findings from Nuspire’s Q1 2022 Threat Report include:

• Incidences of malware, botnet and exploit activity increased 4,76%, 12.21% and 3,87% respectively over Q4 2021.

• Visual Basic Applications (VBA) trojans continue to be the top malware variant, comprising nearly 30% of all malware variants. Of note is its activity spiked just prior to Microsoft’s announcement of plans to block VBA macros by default on Office products.

• Brute force attacks – when threat actors guess different combinations of potential passwords until the correct password is discovered – were by far the most popular exploit at 61%.

“Securing expanded risk surfaces today requires that organisations have 20/20 hindsight combined with an over-the-horizon view of current and potential future threats,” said Craig Robinson, program director for security services at IDC. “Understanding the tactics, techniques and procedures (TTPs) that attackers have historically utilised does not lose value over time, as many of these exploits get repeated with slight twists to make them dangerous zero-day exploits. Combining this historical knowledge with curated threat intelligence that shows the current threat landscape is vital for organisations to survive in these dangerous times.”
