botnet | Breaking Cybersecurity News | The Hacker News

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

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

Over the past two years, a shocking  51% of organizations surveyed in a leading industry report have been compromised by a cyberattack.  Yes, over half.  And this, in a world where enterprises deploy  an average of 53 different security solutions  to safeguard their digital domain.  Alarming? Absolutely. A recent survey of CISOs and CIOs, commissioned by Pentera and conducted by Global Surveyz Research, offers a quantifiable glimpse into this evolving battlefield, revealing a stark contrast between the growing risks and the tightening budget constraints under which cybersecurity professionals operate. With this report, Pentera has once again taken a magnifying glass to the state of pentesting to release its annual report about today's pentesting practices. Engaging with 450 security executives from North America, LATAM, APAC, and EMEA—all in VP or C-level positions at organizations with over 1,000 employees—the report paints a current picture of modern security validation prac

In a coordinated International cyber operation, Europol with the help of international law enforcement agencies has taken down what it called "one of the longest-running malware families in existence" known as Andromeda. Andromeda , also known as Win32/Gamarue, is an infamous HTTP-based modular botnet that has been around for several years now, and infecting computers with it's malicious intentions ever since. The primary goal of Andromeda bot is to distribute other malware families for mass global malware attacks. The botnet has been associated with at least 80 malware families, and in the last six months, it was detected (or blocked) on an average of more than 1 million machines per month. Last year, law enforcement agencies took down the criminal infrastructure of the infamous Avalanche botnet in a similar massive international cyber operation. Avalanche botnet was used as a delivery platform to spread other malware families, including Andromeda. While in

Mining cryptocurrencies can be a costly investment as it takes a monstrous amount of computing power, and thus hackers have started using malware that steals computing resources of computers it hijacks to make lots of dollars in digital currency. Security researchers at security firm ESET have spotted one such malware that infected hundreds of Windows web servers with a malicious cryptocurrency miner and helped cybercriminals made more than $63,000 worth of Monero (XMR) in just three months. According to a report published by ESET today, cybercriminals only made modifications to legitimate open source Monero mining software and exploited a known vulnerability in Microsoft IIS 6.0 to secretly install the miner on unpatched Windows servers. Although ESET's investigation does not identify the attackers, it reports that the attackers have been infecting unpatched Windows web servers with the cryptocurrency miner since at least May 2017 to mine 'Monero,' a Bitcoin-like

The United States government has released a rare alert about an ongoing, eight-year-long North Korean state-sponsored hacking operation. The joint report from the FBI and U.S. Department of Homeland Security (DHS) provided details on " DeltaCharlie ," a malware variant used by " Hidden Cobra " hacking group to infect hundreds of thousands of computers globally as part of its DDoS botnet network. According to the report, the Hidden Cobra group of hackers are believed to be backed by the North Korean government and are known to launch cyber attacks against global institutions, including media organizations, aerospace and financial sectors, and critical infrastructure. While the US government has labeled the North Korean hacking group Hidden Cobra, it is often known as Lazarus Group and Guardians of Peace – the one allegedly linked to the devastating WannaCry ransomware menace that shut down hospitals and businesses worldwide.
