A team of security researchers—which majorly focuses on finding clever ways to get into air-gapped computers by exploiting little-noticed emissions of a computer's components like light, sound and heat —have published another research showcasing that they can steal data not only from an air gap computer but also from a computer inside a Faraday cage. Air-gapped computers are those that are isolated from the Internet and local networks and so, are believed to be the most secure devices that are difficult to infiltrate. Whereas, Faraday cages are metallic enclosures that even blocks all electromagnetic signals, such as Wi-Fi, Bluetooth, cellular and other wireless communications, making any device kept inside the cage, even more, isolate from outside networks. However, Cybersecurity Research Center at Israel's Ben Gurion University, directed by 38-year-old Mordechai Guri, has developed two techniques that helped them exfiltrate data from computers placed inside a Faraday

Security researchers have discovered a custom-built piece of malware that's wreaking havoc in Asia for past several months and is capable of performing nasty tasks, like password stealing, bitcoin mining, and providing hackers complete remote access to compromised systems. Dubbed Operation PZChao , the attack campaign discovered by the security researchers at Bitdefender have been targeting organizations in the government, technology, education, and telecommunications sectors in Asia and the United States. Researchers believe nature, infrastructure, and payloads, including variants of the Gh0stRAT trojan, used in the PZChao attacks are reminiscent of the notorious Chinese hacker group— Iron Tiger . However, this campaign has evolved its payloads to drop trojan, conduct cyber espionage and mine Bitcoin cryptocurrency. The PZChao campaign is attacking targets across Asia and the U.S. by using similar attack tactics as of Iron Tiger, which, according to the researchers, si

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

A simple yet serious application-level denial of service (DoS) vulnerability has been discovered in WordPress CMS platform that could allow anyone to take down most WordPress websites even with a single machine—without hitting with a massive amount of bandwidth, as required in network-level DDoS attacks to achieve the same. Since the company has denied patching the issue, the vulnerability ( CVE-2018-6389 ) remains unpatched and affects almost all versions of WordPress released in last nine years, including the latest stable release of WordPress (Version 4.9.2). Discovered by Israeli security researcher Barak Tawily , the vulnerability resides in the way " load-scripts.php ," a built-in script in WordPress CMS, processes user-defined requests. For those unaware, load-scripts.php file has only been designed for admin users to help a website improve performance and load page faster by combining (on the server end) multiple JavaScript files into a single request.

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

Coincheck, a Tokyo-based cryptocurrency exchange, has suffered what appears to be the biggest hack in the history of cryptocurrencies, losing $532 million in digital assets (nearly $420 million in NEM tokens and $112 in Ripples ). In 2014, Mt Gox , one of the largest bitcoin exchange at that time, filed for bankruptcy after admitting it had lost $450 million worth of Bitcoins. Apparently, the cryptocurrency markets reacted negatively to the news, which resulted in 5% drop in Bitcoin price early this morning. In a blog post published today, the Tokyo-based cryptocurrency exchange confirmed the cyber heist without explaining how the tokens were stolen, and abruptly froze most of its services, including deposits, withdrawals and trade of almost all cryptocurrencies, except Bitcoin. Coincheck also said the exchange had even stopped deposits into NEM cryptocurrencies, which resulted in 16.5% drop in NEM coin value, as well as other deposit methods including credit cards. Durin

Are you using Linux or Mac OS? If you think your system is not prone to viruses, then you should read this. Wide-range of cybercriminals are now using a new piece of 'undetectable' spying malware that targets Windows, macOS, Solaris and Linux systems. Just last week we published a detailed article on the report from EFF/Lookout that revealed a new advanced persistent threat (APT) group, called Dark Caracal , engaged in global mobile espionage campaigns. Although the report revealed about the group's successful large-scale hacking operations against mobile phones rather than computers, it also shed light on a new piece of cross-platform malware called CrossRAT (version 0.1), which is believed to be developed by, or for, the Dark Caracal group. CrossRAT is a cross-platform remote access Trojan that can target all four popular desktop operating systems, Windows, Solaris, Linux, and macOS, enabling remote attackers to manipulate the file system, take screenshots, ru

As many non-tech savvy people think that Bitcoin looks like a Gold coin as illustrated in many stock images, perhaps these robbers also planned to rob a cryptocurrency exchange thinking that way. All jokes apart, we saw one such attempt on Tuesday morning, when three men armed with handguns entered the offices of a Canadian Bitcoin exchange in Ottawa, and restrained four of its employees. The intruders then struck one of the employees in the head with a handgun, asking them to make an outbound transaction from the cryptocurrency exchange. A fifth employee in another cabin, who remained unseen in an office, called the police before any assets could be taken, and the robbers left empty-handed. One of the suspects arrested later Wednesday after arriving police officers saw him run into a ravine north of Colonnade Road and deployed "extensive resources," including K-9 unit officers, to find him, CBC News reports . "Police are looking for two additional suspects,

A Google security researcher has discovered a severe vulnerability in Blizzard games that could allow remote attackers to run malicious code on gamers' computers. Played every month by half a billion users—World of Warcraft, Overwatch, Diablo III, Hearthstone and Starcraft II are popular online games created by Blizzard Entertainment . To play Blizzard games online using web browsers, users need to install a game client application, called ' Blizzard Update Agent ,' onto their systems that run JSON-RPC server over HTTP protocol on port 1120, and " accepts commands to install, uninstall, change settings, update and other maintenance related options. " Google's Project Zero team researcher Tavis Ormandy discovered that the Blizzard Update Agent is vulnerable to a hacking technique called the " DNS Rebinding " attack that allows any website to act as a bridge between the external server and your localhost. Just last week, Ormandy revealed a simi

Cybercriminals have stolen a massive trove of Norway's healthcare data in a recent data breach, which likely impacts more than half of the nation's population. An unknown hacker or group of hackers managed to breach the systems of Health South-East Regional Health Authority (RHF) and reportedly stolen personal info and health records of some 2.9 million Norwegians out of the country's total 5.2 million inhabitants. Health South-East RHA is a healthcare organisation that manages hospitals in Norway's southeast region, including Østfold, Akershus, Oslo, Hedmark, Oppland, Buskerud, Vestfold, Telemark, Aust-Agder and Vest-Agder. The healthcare organisation announced the data breach on Monday after it had been alerted by HelseCERT, the Norwegian CERT department for its healthcare sector, about an "abnormal activity" against computer systems in the region. HelseCERT also said the culprits behind the data breach are "advanced and professional" hacke

Remember " Crackas With Attitude "? A notorious pro-Palestinian hacking group behind a series of embarrassing hacks against United States intelligence officials and leaked the personal details of 20,000 FBI agents , 9,000 Department of Homeland Security officers, and some number of DoJ staffers in 2015. Believe or not, the leader of this hacking group was just 15-years-old when he used "social engineering" to impersonate CIA director and unauthorisedly access highly sensitive information from his Leicestershire home, revealed during a court hearing on Tuesday. Kane Gamble , now 18-year-old, the British teenager hacker targeted then CIA director John Brennan , Director of National Intelligence James Clapper , Secretary of Homeland Security Jeh Johnson, FBI deputy director Mark Giuliano , as well as other senior FBI figures. Between June 2015 and February 2016, Gamble posed as Brennan and tricked call centre and helpline staff into giving away broadband and

The cybersecurity threat landscape has never been more extensive and is most likely to grow exponentially in 2018. Although the original creators of Mirai DDoS botnet have already been arrested and jailed, the variants of the infamous IoT malware are still in the game due to the availability of its source code on the Internet. Security researchers have spotted a new variant of infamous Mirai IoT malware designed to hijack insecure devices that run on ARC embedded processors. Until now, Mirai and its variants have been targeting CPU architectures— including x86, ARM, Sparc, MIPS, PowerPC and Motorola 6800 —deployed in millions of Internet of Things (IoT) devices. Dubbed Okiru , the new Mirai variant, first spotted by @unixfreaxjp from MalwareMustDie team and notified by independent researcher Odisseus , is a new piece of ELF malware that targets ARC-based embedded devices running Linux operating system. " This is the FIRST TIME ever in the history of computer eng

Recently uncovered two huge processor vulnerabilities called Meltdown and Spectre have taken the whole world by storm, while vendors are rushing out to patch the vulnerabilities in its products. The issues apply to all modern processors and affect nearly all operating systems (Windows, Linux, Android, iOS, macOS, FreeBSD, and more), smartphones and other computing devices made in the past 20 years. What are Spectre and Meltdown? We have explained both , Meltdown (CVE-2017-5754) and Spectre (CVE-2017-5753, CVE-2017-5715), exploitation techniques in our previous article. In short, Spectre and Meltdown are the names of security vulnerabilities found in many processors from Intel, ARM and AMD that could allow attackers to steal your passwords, encryption keys and other private information. Both attacks abuse 'speculative execution' to access privileged memory—including those allocated for the kernel—from a low privileged user process like a malicious app running on a

Remember how some cybercriminals shut down most of Washington D.C. police's security cameras for four days ahead of President Donald Trump's inauguration earlier this year? Just a few days after the incident, British authorities arrested two people in the United Kingdom, identified as a British man and a Swedish woman, both 50-year-old, on request of U.S. officials. But now US federal court affidavit  has revealed that two Romanian nationals were behind the attack that hacked into 70% of the computers that control Washington DC Metropolitan Police Department's surveillance camera network in January this year, CNN reports. The two suspects—Mihai Alexandru Isvanca, 25, and Eveline Cismaru, 28—were arrested in Bucharest on December 15 on charges of conspiracy to commit wire fraud and various forms of computer fraud. According to the criminal complaint unsealed in Washington, the pair hacked 123 of the Metropolitan Police Department's 187 outdoor surveillance c

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

Security researchers have discovered multiple attack campaigns conducted by an established Chinese criminal group that operates worldwide, targeting database servers for mining cryptocurrencies, exfiltrating sensitive data and building a DDoS botnet. The researchers from security firm GuardiCore Labs have analyzed thousands of attacks launched in recent months and identified at least three attack variants— Hex, Hanako, and Taylor —targeting different MS SQL and MySQL servers for both Windows and Linux. The goals of all the three variants are different—Hex installs cryptocurrency miners and remote access trojans (RATs) on infected machines, Taylor installs a keylogger and a backdoor, and Hanako uses infected devices to build a DDoS botnet. So far, researchers have recorded hundreds of Hex and Hanako attacks and tens of thousands of Taylor attacks each month and found that most compromised machines are based in China, and some in Thailand, the United States, Japan and others.

The North Korean hacking group has turned greedy. Security researchers have uncovered a new widespread malware campaign targeting cryptocurrency users, believed to be originated from Lazarus Group , a state-sponsored hacking group linked to the North Korean government. Active since 2009, Lazarus Group has been attributed to many high profile attacks, including Sony Pictures Hack , $81 million heists from the Bangladesh Bank , and the latest — WannaCry . The United States has officially blamed North Korea for global WannaCry ransomware attack that infected hundreds of thousands of computers across more than 150 countries earlier this year. In separate news, security experts have blamed Lazarus group for stealing bitcoins worth millions from the South Korean exchange Youbit , forcing it to shut down and file for bankruptcy after losing 17% of its assets. Researchers from security firm Proofpoint have published a new report, revealing a connection between Lazarus Group and a
