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 ?

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 ?

Mirai Linux Trojan corrals IoT devices into DDoS botnets

Mirai, a newly discovered and still poorly detected piece of Linux malware, is being used to rope IoT devices into DDoS botnets. Researchers from MalwareMustDie have recently gotten their hands on several variants of the threat, and have discovered the following things: It comes in the form of an ELF file (typical for executable files in Unix and Unix-like systems) It targets mostly routers, DVR or WebIP cameras, Linux servers, and Internet of Things devices … More ?

Global mobile deep packet inspection market explodes

The global mobile deep packet inspection (DPI) market will grow at an impressive CAGR of almost 22% until 2020, according to Technavio. Stateful packet inspection Stateful packet inspection (SPI), also known as shallow packet inspection technology, was widely used for detecting abnormal packets by inspecting the packet headers only. SPI was not able to detect many new network attacks such as network intrusion detection systems (NIDS) evasion and distributed denial of service. Thus, DPI became … More ?
