Hacker-Angriff auf das RKI: Webseite des Instituts für Stunden lahmgelegt | #CyberSecurity #DDoS

Hacker-Angriff auf das RKI: Webseite des Instituts für Stunden lahmgelegt | #CyberSecurity #DDoS | ICT Security-Sécurité PC et Internet | Scoop.it

Das Robert-Koch-Institut ist Opfer eines Angriffs von Cyberkriminellen geworden. Die Webseite der Behörde wurde dabei für mehrere Stunden lahmgelegt. Wer hinter den Attacken steht, ist noch unklar.


Cyberkriminelle haben am vergangenen Donnerstag die Webseite des Robert Koch-Instituts (RKI) zeitweise lahmgelegt. Der Angriff sei morgens zwischen 8.00 und 10.00 Uhr erfolgt, sagte ein Sprecher des Informationstechnikzentrums Bund (ITZBund). Er bestätigte damit einen entsprechenden Bericht des Nachrichtenmagazins "Spiegel". Es habe sich um einem sogenannten DDOS-Angriff (Distributed Denial of Service) gehandelt.


Bei DDoS-Attacken werden Server mit einer Flut sinnloser Anfragen in die Knie gezwungen. So können Angriffe im großen Stil ausgeführt werden. Wer hinter der Attacke steckt, sei bisher nicht bekannt und werde noch untersucht, heißt es vom ITZBund. Der staatliche IT-Dienstleister betreibt die Webseite des RKI.

Désormais un simple PC suffit pour faire tomber les plus gros sites | #CyberSecurity #DDos | ICT Security-Sécurité PC et Internet | Scoop.it
Pour faire tomber des sites avec une attaque de type « Déni de service » (DDoS), plus besoin d’utiliser un grand nombre d’ordinateurs ou de louer les services d'un botnet, un seul PC peut suffire !
Les chercheurs danois de TDC ont révélé une nouvelle technique d’attaque qu’ils ont baptisés BlackNurse. Sa particularité est qu’elle ne nécessite qu’un seul ordinateur et une liaison internet de bonne qualité (au moins 15 à 18 Mbit/s). En comparaison, les dernières attaques DDoS contre le les fournisseurs Dyn et OVH ont nécessité des débits de l’ordre de 1 Tbit/s.

Comment arrive-t-elle à être aussi efficace en nécessitant si peu de puissance de feu ? Au lieu d’envoyer une grande quantité de trafic sur les serveurs, BlackNurse envoie des paquets de données spécifiques (Internet Control Message Protocol) qui sont utilisés par les appareils réseau pour la transmission de messages d’erreur. Ces paquets vont surcharger les processeurs des pare-feu conçus par des constructeurs connus tels que Cisco ou Palo Alto Networks.

Nobody knows for sure who launched a massive Mirai botnet attack against parts of the internet on Friday, but there’s no denying that they made themselves felt.

 

Hundreds of thousands, if not millions, of devices are thought to have been compromised by Mirai and recruited into the botnet. That botnet was then put to work, launching a distributed denial-of-service attack against the Dyn domain name service that had a dramatic impact on some of the world’s most popular websites, making them inaccessible to many internet users.

DDoS on Dyn Impacts Twitter, Spotify, Reddit | #CyberSecurity #CyberAttacks

DDoS on Dyn Impacts Twitter, Spotify, Reddit | #CyberSecurity #CyberAttacks | ICT Security-Sécurité PC et Internet | Scoop.it

Criminals this morning massively attacked Dyn, a company that provides core Internet services for Twitter, SoundCloud, Spotify, Reddit and a host of other sites, causing outages and slowness for many of Dyn’s customers.

Twitter is experiencing problems, as seen through the social media platform Hootsuite.

In a statement, Dyn said that this morning, October 21, Dyn received a global distributed denial of service (DDoS) attack on its DNS infrastructure on the east coast starting at around 7:10 a.m. ET (11:10 UTC).

“DNS traffic resolved from east coast name server locations are experiencing a service interruption during this time. Updates will be posted as information becomes available,” the company wrote.

DYN encouraged customers with concerns to check the company’s status page for updates and to reach out to its technical support team.

DDoS attacks are soaring, says new report

DDoS attacks are soaring, says new report | ICT Security-Sécurité PC et Internet | Scoop.it
The number of DDoS attacks is soaring, according to Akamai’s latest State of the Internet report. But attack characteristics have shifted, as attackers have moved to quick strikes based on rented botnets, and are relying more heavily on reflection attacks that exploit compromised internet services.

Akamai reports that attacks were up a whopping 149% compared to this time last year – though it’s worth noting that the data reflects Akamai’s changing customer base, not all DDoS attacks everywhere.

Last quarter, the average DDoS attack against an Akamai customer clocked in at just under 15 hours, barely half the average length from a year before. And, measured by data volume, there were fewer mega-attacks: only five exceeding 100 Gbit/sec, compared with nine a year before.

Drilling down, Akamai found that the vast majority of DDoS attacks are now launched from stresser/booter-based botnets (such as the one run by Lizard Squad) that bounce traffic off servers that run compromised versions of certain services. These botnets aim to maximize attack bandwidth and intensity, so they deliver larger (but fewer) packets faster.

Trend Micro details new IoT DDoS threat | #CyberSecurity #Awareness #Linux #Cameras

Trend Micro details new IoT DDoS threat | #CyberSecurity #Awareness #Linux #Cameras | ICT Security-Sécurité PC et Internet | Scoop.it
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.

DDoSing has evolved in the vacuum left by IoT's total absence of security | #CyberSecurity #Botnet #DDoS | ICT Security-Sécurité PC et Internet | Scoop.it
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.

Mirai botnet attackers are trying to knock an entire country offline | #CyberSecurity #CyberAttacks #IoT 

Mirai botnet attackers are trying to knock an entire country offline | #CyberSecurity #CyberAttacks #IoT  | ICT Security-Sécurité PC et Internet | Scoop.it

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.

Der Bot im Babyfon

24. Oktober 2016 | Am Freitag vergangener Woche waren die Webseiten von Internetriesen wie Amazon, Twitter, PayPal oder Netflix über Stunden nur schwierig zu erreichen. Grund war eine digitale Attacke auf den Internetdienstleister Dyn. Dessen Aufgabe ist, die Domain-Namen wie amazon.com in die dazugehörigen IP-Adressen zu übersetzen. Mit einer sogenannten DDoS-Attacke, also dem massenhaften wiederholten Anfragen des Dienstes, wurde dieser derart überlastet, dass er unter der Last zusammenbrach und in der Folge die Webseiten seiner Kunden nicht erreichbar waren. Derartige Angriffe werden in der Regel mit Hilfe von sogenannten Botnetzen durchgeführt. Diese bestehen üblicherweise aus zahlreichen internetfähigen Geräten wie Computer, Smartphones oder Tablets, die mit Schadsoftware infiziert sind und durch diese - vom Nutzer unbemerkt - fremdgesteuert werden können.

 

Neu an diesem Angriff ist, dass er mit einem Botnetz durchgeführt wurde, das zu großen Teilen aus mit dem Internet verbundenen Haushaltsgeräten (IoT-Geräte) besteht. Das sogenannte Mirai-Botnetz hat dabei auf Grund der großen Anzahl der Geräte eine Bandbreite erreicht, die weit über die bisher bekannter Botnetze hinausgeht. Die Netzwerkkameras, Babyfone oder Kühlschränke, die bereits zum Botnetz gehören, scannen offenbar selbstständig das Internet nach weiteren Geräten, um sie mit Schadsoftware zu infizieren und dem Botnetz hinzuzufügen. Das Mirai-Botnetz wächst also stetig weiter.
