75% of the 'Left to Get Hacked' Redis Servers Found Infected

75% of the 'Left to Get Hacked' Redis Servers Found Infected

Jun 04, 2018
Despite the continual emergence of new cyber attacks because of misconfigured servers and applications, people continue to ignore security warnings. A massive malware campaign designed to target open Redis servers, about which researchers warned almost two months ago, has now grown and already hijacked at least 75% of the total servers running publicly accessible Redis instances. Redis, or REmote DIctionary Server, is an open source, widely popular data structure tool that can be used as an in-memory distributed database, message broker or cache. Since it is designed to be accessed inside trusted environments, it should not be exposed on the Internet. Dubbed RedisWannaMine , a similar malware leveraging same loophole was discovered in late March by data center security vendor Imperva and designed to drop a cryptocurrency mining script on the targeted servers—both database and application. According to Imperva's March blog post , this cryptojacking threat was "more c
Hackers are exploiting a new zero-day flaw in GPON routers

Hackers are exploiting a new zero-day flaw in GPON routers

May 23, 2018
Even after being aware of various active cyber attacks against the GPON Wi-Fi routers, if you haven't yet taken them off the Internet, then be careful—because a new botnet has joined the GPON party, which is exploiting an undisclosed zero-day vulnerability in the wild. Security researchers from Qihoo 360 Netlab have warned of at least one botnet operator exploiting a new zero-day vulnerability in the Gigabit-capable Passive Optical Network (GPON) routers, manufactured by South Korea-based DASAN Zhone Solutions. The botnet, dubbed TheMoon, which was first seen in 2014 and has added at least 6 IoT device exploits to its successor versions since 2017, now exploits a newly undisclosed zero-day flaw for Dasan GPON routers. Netlab researchers successfully tested the new attack payload on two different versions of GPON home router, though they didn't disclose details of the payload or release any further details of the new zero-day vulnerability to prevent more attacks.

Super Low RPO with Continuous Data Protection: Dial Back to Just Seconds Before an Attack Zerto , a Hewlett Packard Enterprise company, can help you detect and recover from ransomware in near real-time. This solution leverages continuous data protection (CDP) to ensure all workloads have the lowest recovery point objective (RPO) possible. The most valuable thing about CDP is that it does not use snapshots, agents, or any other periodic data protection methodology. Zerto has no impact on production workloads and can achieve RPOs in the region of 5-15 seconds across thousands of virtual machines simultaneously. For example, the environment in the image below has nearly 1,000 VMs being protected with an average RPO of just six seconds! Application-Centric Protection: Group Your VMs to Gain Application-Level Control   You can protect your VMs with the Zerto application-centric approach using Virtual Protection Groups (VPGs). This logical grouping of VMs ensures that your whole applica
Biggest-Ever DDoS Attack (1.35 Tbs) Hits Github Website

Biggest-Ever DDoS Attack (1.35 Tbs) Hits Github Website

Mar 02, 2018
On Wednesday, February 28, 2018, GitHub's code hosting website hit with the largest-ever distributed denial of service (DDoS) attack that peaked at record 1.35 Tbps. Interestingly, attackers did not use any botnet network, instead weaponized misconfigured Memcached servers to amplify the DDoS attack. Earlier this week we published a report detailing how attackers could abuse Memcached, popular open-source and easily deployable distributed caching system, to launch over 51,000 times powerful DDoS attack than its original strength. Dubbed Memcrashed , the amplification DDoS attack works by sending a forged request to the targeted Memcrashed server on port 11211 using a spoofed IP address that matches the victim's IP. A few bytes of the request sent to the vulnerable server trigger tens of thousands of times bigger response against the targeted IP address. "This attack was the largest attack seen to date by Akamai, more than twice the size of the September 2016

Cryptocurrency Mining Malware Infected Over Half-Million PCs Using NSA Exploit

Cryptocurrency Mining Malware Infected Over Half-Million PCs Using NSA Exploit

Feb 01, 2018
2017 was the year of high profile data breaches and ransomware attacks, but from the beginning of this year, we are noticing a faster-paced shift in the cyber threat landscape, as cryptocurrency-related malware is becoming a popular and profitable choice of cyber criminals. Several cybersecurity firms are reporting of new cryptocurrency mining viruses that are being spread using EternalBlue —the same NSA exploit that was leaked by the hacking group Shadow Brokers and responsible for the devastating widespread ransomware threat WannaCry . Researchers from Proofpoint discovered a massive global botnet dubbed "Smominru," a.k.a Ismo, that is using EternalBlue SMB exploit (CVE-2017-0144) to infect Windows computers to secretly mine Monero cryptocurrency, worth millions of dollars, for its master. Active since at least May 2017, Smominru botnet has already infected more than 526,000 Windows computers, most of which are believed to be servers running unpatched versions of Wi
Satori IoT Botnet Exploits Zero-Day to Zombify Huawei Routers

Satori IoT Botnet Exploits Zero-Day to Zombify Huawei Routers

Dec 23, 2017
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
