Researchers from a number of cybersecurity giants are banding together to fight a vast botnet comprised of some 70,000 devices blamed for a string of DDoS attacks in recent weeks.
Drawing striking parallels to last year’s Mirai botnet attacks, the new WireX botnet has, in recent weeks, pummeled a numbero f content providers and delivery networks with traffic from hijacked Android devices. Content delivery giant Akamai discovered the botnet malware after researching an attack on one of its clients. Upon closer inspection, WireX was revealed to be using a network of malware-infected devices to inundate targets with HTTP requests purporting to be legitimate traffic. The key difference from Mirai, which used compromised IoT and networking devices, sees WireX whipping up a botnet of at least 70,000 Android devices from over 100 countries, according to cybersecurity journalist Brian Krebs.
Although WireX was active from August 2, the majority of the attacks did not begin until August 15 before it eventually triggered red flags within the cybersecurity community on August 17.
“These discoveries were only possible due to open collaboration between DDoS targets, DDoS mitigation companies, and intelligence firms, wrote Akamai. “Every player had a different piece of the puzzle; without contributions from everyone, this botnet would have remained a mystery.”
After looking into the DDoS botnet malware targeting devices on its Android platform, Google discovered hundreds of seemingly benign apps on its Play Store spreading the malware and infecting victims’ Android devices.
In a statement, Google revealed:
We identified approximately 300 apps associated with the issue, blocked them from the Play Store, and we’re in the process of removing them from all affected devices. The researchers’ findings, combined with our own analysis, have enabled us to better protect Android users, everywhere.
Some of the rogue apps spreading the malware were discovered to be masquerading as legitimate applications including ringtone apps, video players, storage managers and more.
The FBI was also involved in the investigation into the botnet, which is now being curbed and eradicated.
