IoT Botnets Found Using Default Credentials for C&C Server Databases

IoT Botnets Found Using Default Credentials for C&C Server Databases

June 05, 2018Mohit Kumar
Not following cybersecurity best practices could not only cost online users but also cost cybercriminals. Yes, sometimes hackers don't take best security measures to keep their infrastructure safe. A variant of IoT botnet, called Owari , that relies on default or weak credentials to hack insecure IoT devices was found itself using default credentials in its MySQL server integrated with command and control (C&C) server, allowing anyone to read/write their database. Ankit Anubhav, the principal security researcher at IoT security firm NewSky Security, who found the botnets, published a blog post about his findings earlier today, detailing how the botnet authors themselves kept an incredibly week username and password combination for their C&C server's database. Guess what the credentials could be? Username: root Password: root These login credentials helped Anubhav gain access to the botnet and fetch details about infected devices, the botnet authors who
Satori IoT Botnet Exploits Zero-Day to Zombify Huawei Routers

Satori IoT Botnet Exploits Zero-Day to Zombify Huawei Routers

December 23, 2017Swati Khandelwal
Although the original creators of the infamous IoT malware Mirai have already been arrested and sent to jail, the variants of the notorious botnet are still in the game due to the availability of its source code on the Internet. Hackers have widely used the infamous IoT malware to quietly amass an army of unsecured internet-of-things devices , including home and office routers, that could be used at any time by hackers to launch Internet-paralyzing DDoS attacks . Another variant of Mirai has hit once again, propagating rapidly by exploiting a zero-day vulnerability in a Huawei home router model. Dubbed Satori (also known as Okiru), the Mirai variant has been targeting Huawei's router model HG532, as Check Point security researchers said they tracked hundreds of thousands of attempts to exploit a vulnerability in the router model in the wild. Identified initially by Check Point researchers late November, Satori was found infecting more than 200,000 IP addresses in just
New Mirai Botnet Variant Found Targeting ZyXEL Devices In Argentina

New Mirai Botnet Variant Found Targeting ZyXEL Devices In Argentina

November 28, 2017Swati Khandelwal
While tracking botnet activity on their honeypot traffic, security researchers at Chinese IT security firm Qihoo 360 Netlab discovered a new variant of Mirai —the well known IoT botnet malware that wreaked havoc last year. Last week, researchers noticed an increase in traffic scanning ports 2323 and 23 from hundreds of thousands of unique IP addresses from Argentina in less than a day. The targeted port scans are actively looking for vulnerable internet-connected devices manufactured by ZyXEL Communications using two default telnet credential combinations— admin/CentryL1nk and admin/QwestM0dem —to gain root privileges on the targeted devices. Researchers believe (instead "quite confident") this ongoing campaign is part of a new Mirai variant that has been upgraded to exploit a newly released vulnerability (identified as CVE-2016-10401 ) in ZyXEL PK5001Z modems. "ZyXEL PK5001Z devices have zyad5001 as the su (superuser) password, which makes it easier for rem
New Rapidly-Growing IoT Botnet Threatens to Take Down the Internet

New Rapidly-Growing IoT Botnet Threatens to Take Down the Internet

October 21, 2017Wang Wei
Just a year after Mirai —biggest IoT-based malware that caused vast Internet outages by launching massive DDoS attacks—completed its first anniversary, security researchers are now warning of a brand new rapidly growing IoT botnet. Dubbed ' IoT_reaper ,' first spotted in September by researchers at firm Qihoo 360, the new malware no longer depends on cracking weak passwords; instead, it exploits vulnerabilities in various IoT devices and enslaves them into a botnet network. IoT_reaper malware currently includes exploits for nine previously disclosed vulnerabilities in IoT devices from following manufactures: Dlink (routers) Netgear (routers) Linksys (routers) Goahead (cameras) JAWS (cameras) AVTECH (cameras) Vacron (NVR) Researchers believe IoT_reaper malware has already infected nearly two million devices and growing continuously at an extraordinary rate of 10,000 new devices per day. This is extremely worrying because it took only 100,000 infected devices
Linux Trojan Using Hacked IoT Devices to Send Spam Emails

Linux Trojan Using Hacked IoT Devices to Send Spam Emails

September 22, 2017Wang Wei
Botnets, like Mirai , that are capable of infecting Linux-based internet-of-things (IoT) devices are constantly increasing and are mainly designed to conduct Distributed Denial of Service (DDoS) attacks, but researchers have discovered that cybercriminals are using botnets for mass spam mailings. New research conducted by Russian security firm Doctor Web has revealed that a Linux Trojan, dubbed Linux.ProxyM that cybercriminals use to ensure their online anonymity has recently been updated to add mas spam sending capabilities to earn money. The Linux.ProxyM Linux Trojan, initially discovered by the security firm in February this year, runs a SOCKS proxy server on an infected IoT device and is capable of detecting honeypots in order to hide from malware researchers. Linux.ProxyM can operate on almost all Linux device, including routers, set-top boxes, and other equipment having the following architectures: x86, MIPS, PowerPC, MIPSEL, ARM, Motorola 68000, Superh and SPARC.
New IoT Bill Proposes Security Standards for Smart Devices

New IoT Bill Proposes Security Standards for Smart Devices

August 02, 2017Mohit Kumar
By this time, almost every one of you owns at least one internet-connected device—better known as the " Internet of things "—at your home, but how secure is your device? We have recently seen Car hacking that could risk anyone's life, Hoverboard hacking, even hacking of a so-called smart Gun and also the widespread hacks of insecure CCTV cameras, routers and other internet-connected home appliances. But this did not stop vendors from selling unsecured Internet-connected smart devices, and customers are buying them without giving a sh*t about the security of their smart devices. However, the massive cyber attack on a popular DNS service provider that shut down a large portion of the Internet last year made us all fear about the innocent-looking IoT devices, which surround us every day, but actually, poses a threat to global cyber security. Not anymore! A bipartisan group of senators have now introduced a new bill aimed at securing internet-connected devices b
Hajime ‘Vigilante Botnet’ Growing Rapidly; Hijacks 300,000 IoT Devices Worldwide

Hajime ‘Vigilante Botnet’ Growing Rapidly; Hijacks 300,000 IoT Devices Worldwide

April 27, 2017Swati Khandelwal
Last week, we reported about a so-called 'vigilante hacker' who hacked into at least 10,000 vulnerable 'Internet of Things' devices, such as home routers and Internet-connected cameras, using a botnet malware in order to supposedly secure them. Now, that vigilante hacker has already trapped roughly 300,000 devices in an IoT botnet known as Hajime , according to a new report published Tuesday by Kaspersky Lab, and this number will rise with each day that passes by. The IoT botnet malware was emerged in October 2016, around the same time when the infamous Mirai botnet threatened the Internet last year with record-setting distributed denial-of-service (DDoS) attacks against the popular DNS provider Dyn. How the Hajime IoT Botnet Works Hajime botnet works much like Mirai by spreading itself via unsecured IoT devices that have open Telnet ports and uses default passwords and also uses the same list of username and password combinations that Mirai is programm

It should be noted that hacking a system for unauthorised access that does not belong to you is an illegal practice, no matter what's the actual intention behind it. Now I am pointing out this because reportedly someone, who has been labeled as a 'vigilante hacker' by media, is hacking into vulnerable 'Internet of Things' devices in order to supposedly secure them. This is not the first time when any hacker has shown vigilance, as we have seen lots of previous incidents in which hackers have used malware to compromise thousands of devices, but instead of hacking them, they forced owners to make them secure. Dubbed Hajime , the latest IoT botnet malware, used by the hacker, has already infected at least 10,000 home routers, Internet-connected cameras, and other smart devices. But reportedly, it's an attempt to wrestle their control from Mirai and other malicious threats. Mirai is an IoT botnet that threatened the Internet last year with record-sett

The Internet-connected devices are growing at an exponential rate, and so are threats to them. Due to the insecure implementation, a majority of Internet-connected embedded devices, including Smart TVs, Refrigerators, Microwaves, Security Cameras, and printers, are routinely being hacked and used as weapons in cyber attacks. We have seen IoT botnets like Mirai – possibly the biggest IoT-based malware threat that emerged late last year and caused vast internet outage by launching massive DDoS attacks against DynDNS provider – which proves how easy it is to hack these connected devices. Now, a security researcher is warning of another IoT threat involving Smart TVs that could allow hackers to take complete control of a wide range of Smart TVs at once without having any physical access to any of them. Researcher Shows Live Hacking Demonstration   The proof-of-concept exploit for the attack, developed by Rafael Scheel of cyber security firm Oneconsult, uses a low-cost tra
New Windows Trojan Spreads MIRAI Malware To Hack More IoT Devices

New Windows Trojan Spreads MIRAI Malware To Hack More IoT Devices

February 10, 2017Swati Khandelwal
MIRAI – possibly the biggest IoT-based malware threat that emerged last year, which caused vast internet outage in October last year by launching massive distributed denial-of-service (DDoS) attacks against the popular DNS provider Dyn . Now, the infamous malware has updated itself to boost its distribution efforts. Researchers from Russian cyber-security firm Dr.Web have now uncovered a Windows Trojan designed to built with the sole purpose of helping hackers spread Mirai to even more devices. Mirai is a malicious software program for Linux-based internet-of-things (IoT) devices which scan for insecure IoT devices, enslaves them into a botnet network, and then used them to launch DDoS attacks, and spreads over Telnet by using factory device credentials. It all started early October last year when a hacker publicly released the source code of Mirai . Dubbed Trojan.Mirai.1, the new Trojan targets Windows computers and scans the user's network for compromisable Linux-

5 Major Russian Banks Hit With Powerful DDoS Attacks

November 11, 2016Swati Khandelwal
Distributed Denial of Service (DDoS) attacks have risen enormously in past few months and, mostly, they are coming from hacked and insecure internet-connected devices, most commonly known as Internet of Things (IoT). Recent DDoS attack against DNS provider Dyn that brought down a large chunk of the Internet came from hacked and vulnerable IoT devices such as DVRs, security cameras, and smart home appliances. This DDoS was the biggest cyber attack the world has ever seen. Now, in the latest incident, at least five Russian banks have been subject to a swathe of DDoS attacks for two days, said the Russian banking regulator. The state-owned Sberbank was one of the five targets of the attacks that began on last Tuesday afternoon and lasted over the next two days. According to Kaspersky Lab, the longest attack last for 12 hours and peaked at 660,000 requests per second came from a botnet of at least 24,000 hacked devices located in 30 countries. Although the culprit appears

New IoT Botnet Malware Discovered; Infecting More Devices Worldwide

November 01, 2016Swati Khandelwal
The whole world is still dealing with the Mirai IoT Botnet that caused vast internet outage last Friday by launching massive distributed denial of service (DDoS) attacks against the DNS provider Dyn, and researchers have found another nasty IoT botnet. Security researchers at MalwareMustDie have discovered a new malware family designed to turn Linux-based insecure Internet of Things (IoT) devices into a botnet to carry out massive DDoS attacks. Dubbed Linux/IRCTelnet , the nasty malware is written in C++ and, just like Mirai malware , relies on default hard-coded passwords in an effort to infect vulnerable Linux-based IoT devices. The IRCTelnet malware works by brute-forcing a device's Telnet ports, infecting the device's operating system, and then adding it to a botnet network which is controlled through IRC (Internet Relay Chat) – an application layer protocol that enables communication in the form of text. So, every infected bot (IoT device) connects to a mali

You might be surprised to know that your security cameras, Internet-connected toasters and refrigerators may have inadvertently participated in the massive cyber attack that broke a large portion of the Internet on Friday. That's due to massive Distributed Denial of Service (DDoS) attacks against Dyn, a major domain name system (DNS) provider that many sites and services use as their upstream DNS provider for turning IP addresses into human-readable websites. The result we all know: Twitter, GitHub, Amazon, Netflix, Pinterest, Etsy, Reddit, PayPal, and AirBnb, were among hundreds of sites and services that were rendered inaccessible to Millions of people worldwide for several hours. Why and How the Deadliest DDoS Attack Happened It was reported that the Mirai bots were used in the massive DDoS attacks against DynDNS, but they "were separate and distinct" bots from those used to execute record-breaking DDoS attack against French Internet service and hosting

If you are concerned about the insecurity of Internet of Things, have good hands at programming and know how to hack smart devices, then you can grab an opportunity to earn $50,000 in prize money for discovering the non-traditional ways to secure IoT devices. Internet of Things (IoT) market is going to expand rapidly over the next decade. We already have 6.5 billion to 8 billion IoT devices connected to the Internet worldwide, and the number is expected to reach 50 billion by 2020. While IoT is going to improve life for many, the number of security risks due to lack of stringent security measures and encryption mechanisms in the devices have increased exponentially. This rise in the number of security risks would continue to widen the attack surface, giving hackers a large number of entry points to affect you some or the other way. Recently, we saw a record-breaking DDoS attack (Distributed Denial of Service) against the France-based hosting provider OVH that reached over
