The Spike botnet is a Distributed-Denial-of-Service network that consists of machines infected by its payload and a range of Command & Control servers. Infected machines may be forced to commit DDoS attacks at the cost of their system resources, allowing the Spike botnet to crash targeted servers at will. While the Spike botnet shows minimal creativity in terms of its attacks, the Spike botnet has distinguished itself for its broad compatibility with many types of Internet-capable devices. PC users are advised to use anti-malware products to remove Spike botnet Trojans from their systems, and other, vulnerable devices should be patched to block any preventable breaches of security.

A Denial of Service that may Come from Almost Anything

Although botnet Trojans aren't new to the world (the average Trojan-based botnet previously rounded out at twenty thousand machines), updates to old threats continue to provide malware researchers with new threats to inspect. The Spike botnet, which uses a toolkit that third parties may configure for diverse attack campaigns, began its life as a threat solely to Linux PCs. However, its latest updates have granted the Spike botnet's Trojan payloads compatibility with other machines, including:

  • Windows-based PCs. Both 32-bit and 64-bit systems are at risk, albeit by different variants of the Spike botnet's payload.
  • IoT (or 'Internet of Things') devices using Linux. ARM devices frequently are mobile, with a platform architecture favored for cheap production and low power requirements. Examples of ARM devices that could be attacked by a Spike botnet Trojan include smartphones, tablets and PDAs.

Just as with any other botnet infection, a successful installation of a Spike botnet Trojan allows third parties to incorporate the machine into their zombie botnet. From there, instructions may be issued for the machine to simulate Web traffic. When this traffic multiplies itself across a range of infected machines, it may disable bank websites or other, equally-critical Internet services.

The Spike botnet, like most botnets, issues limited or no symptoms for users of infected machines, even after a successful attack. In some cases, unusual spikes in network activity or system resource expenditures may be noticeable.

Pulling the Spike botnet out of Your Network

Although the Spike botnet focuses on initiating attacks that target external servers, rather than the infected machines, its ability to enable remote code execution could be utilized in other ways besides launching DDoS floods. If you suspect a computer of being a part of a Spike botnet, appropriate anti-malware solutions should be put into play immediately. Malware experts haven't identified all of the distribution methods in use by these threats, but, e-mail spam, disguised social networking links and concealed bundles circulated on illegal downloading networks are typical methods.

Trojans that are part of a Spike botnet show few differences from other, similar botnet-based threats. The symptoms of such an infection frequently are minor or nonexistent. However, malware researchers do advise you to be attentive to unusual system resource spikes or inexplicable program slowdowns.
