Linux/IRCTelnet creates new, powerful IoT DDoS botnet

Linux/IRCTelnet (new Aidra), a new piece of Linux malware targeting IoT devices and turning them into DDoS-capable bots, has been spotted and analyzed by one of the researchers who share their discoveries on the MalwareMustDie! blog. Linux/IRCTelnet is an interesting mix of capabilities associated with older malware. The base of Linux/IRCTelnet is the source code of the Aidra bot, used years ago by an anonymous researcher to build a botnet (or, as he called it, … More ?

Can we extinguish the Mirai threat?

The recent massive DDoS attack against DNS provider Dyn has jolted (some of) the general public and legislators, and has opened their eyes to the danger of insecure IoT devices. It is clear by now that it will take joint action by all stakeholders – users, manufacturers, the security industry, ISPs, law enforcement and legislators – to put an end to this particular problem, but it will take quite some time. Theoretical stopgap solutions In … More ?

Building the IoT monster

When Mary Shelley wrote Frankenstein, she imagined the misguided doctor assembling his creature from dead body parts, who instead of elevating science, created something dark and terrible. A modern day Mary might well imagine the monster being assembled, not from arms and legs, from nanny-cams, door locks, and DVRs. It would be hard to miss the events of the past few weeks. In September, security reporter Brian Krebs was hit by a massive DDoS attack. … More ?

130,000 Avtech IP cameras, DVRs can be easily roped into IoT botnets

Security researcher Gergely Eberhardt has unearthed over dozen of vulnerabilities in most IP cameras, NVRs and DVRs by Taiwanese manufacturer Avtech, including things like plaintext storage of administrative password and authentication bypass flaws. Eberhardt, who works for Hungarian security testing outfit Search Lab, says a final tally would likely be even higher, as these vulnerabilities were found within a short period of time and the research was done without a systematic approach. According to the … More ?

53% of DDoS attacks result in additional compromise

DDoS attack volume has remained consistently high and these attacks cause real damage to organizations, according to Neustar. The global response also affirms the prevalent use of DDoS attacks to distract as “smokescreens” in concert with other malicious activities that result in additional compromise, such as viruses and ransomware. “Distributed denial-of-service attacks are no longer isolated events limited to large, highly visible, targets. Sophisticated attacks hit companies of all sizes, in all industries,” said Rob … More ?

Cyber terrorism seen as biggest single future threat

47% of UK IT decision makers (ITDMs) are more worried about cyber terrorism attacks now than they were 12 months ago, according to IP EXPO Europe. This was identified as the biggest cyber security risk in the future (27%), followed by attacks to national infrastructure (13%). In light of this newly perceived risk, more traditional cyber threats such as ransomware and DDoS are rated as a lower risk, with only 11%, 10% and 9% of … More ?

Business still ill-prepared to handle modern DDoS attacks

In September 1996, New York City’s original ISP, Panix, was hit by a SYN flood denial of service attack that took them offline for several days. At a time when only 20 million Americans were online, this was one of the first high profile examples of the growing importance of network and service availability. It also demonstrated how fragile internet infrastructure was at the time. According to an advisory from Carnegie Melon’s CERT, “There is, … More ?
