A pressing cybersecurity risk has emerged just a year following the notorious Mirai botnet attack, which disrupted numerous Internet services through extensive DDoS attacks. Security researchers are now raising alarms about a new IoT botnet known as “IoT_reaper,” first identified by experts from Qihoo 360. This malware has distinct characteristics, primarily exploiting vulnerabilities in IoT devices rather than relying solely on weak password exploits, as seen with its predecessor.
The IoT_reaper malware is reported to have incorporated exploits for nine vulnerabilities affecting devices manufactured by well-known companies such as D-Link, Netgear, and Linksys among others. The rapid proliferation of this new botnet raises significant concerns, as researchers estimate that it may have already compromised nearly two million devices, with an alarming rate of 10,000 new infections each day. This trend poses a potential threat on a scale that could lead to similar, if not more catastrophic disruptions as those caused by Mirai.
Particularly concerning is the fact that Mirai was able to launch a crippling DDoS attack on the DNS provider Dyn with just 100,000 infected devices. This serves as a stark reminder of what could happen given IoT_reaper’s current scale and growth. Researchers have found that the malware is also capable of invoking DNS amplification attacks utilizing more than 100 open DNS resolvers.
As noted by Qihoo 360, while IoT_reaper is still expanding, the ongoing modification of its code by its creators warrants heightened vigilance across industries. Concurrently, researchers from CheckPoint have flagged another potential variant of this threat, named “IoTroop,” which has reportedly infected hundreds of thousands of devices in organizations worldwide. The precise intentions behind this surge are still unclear, leading experts to emphasize the necessity for organizations to implement robust defenses against emerging threats.
The IoTroop malware also takes advantage of vulnerabilities in a variety of Wireless IP Camera devices from manufacturers like GoAhead and TP-Link. With the threat landscape for DDoS attacks poised for significant escalation—potentially reaching tens of terabits per second—it is essential for businesses to bolster their cybersecurity posture.
CheckPoint researchers have warned that we might currently be experiencing a moment of calm before an impending and more significant cyber event. In light of these developments, business owners are urged to remain vigilant regarding their smart device security. Previous discussions on protective measures for IoT devices provide valuable insights for organizations looking to mitigate risk.
In conclusion, as IoT devices permeate business infrastructures, understanding and proactively addressing these vulnerabilities becomes crucial. Engaging with the MITRE ATT&CK framework can help pinpoint potential adversary tactics such as initial access and privilege escalation that may be exploited in these attacks, enabling organizations to fortify their defense mechanisms accordingly.
