Cyber Attack | Breaking Cybersecurity News | The Hacker News

A group of researchers has detailed a new timing vulnerability in Transport Layer Security (TLS) protocol that could potentially allow an attacker to break the encryption and read sensitive communication under specific conditions. Dubbed " Raccoon Attack ," the server-side attack exploits a side-channel in the cryptographic protocol (versions 1.2 and lower) to extract the shared secret key used for secure communications between two parties. "The root cause for this side channel is that the TLS standard encourages non-constant-time processing of the DH secret," the researchers explained their findings in a paper. "If the server reuses ephemeral keys, this side channel may allow an attacker to recover the premaster secret by solving an instance of the Hidden Number Problem." However, the academics stated that the vulnerability is hard to exploit and relies on very precise timing measurements and on a specific server configuration to be exploitable.

Even as Visa issued a warning about a new JavaScript web skimmer known as Baka , cybersecurity researchers have uncovered an authentication flaw in the company's EMV enabled payment cards that permits cybercriminals to obtain funds and defraud cardholders as well as merchants illicitly. The research , published by a group of academics from the ETH Zurich, is a PIN bypass attack that allows the adversaries to leverage a victim's stolen or lost credit card for making high-value purchases without knowledge of the card's PIN, and even trick a point of sale (PoS) terminal into accepting an unauthentic offline card transaction. All modern contactless cards that make use of the Visa protocol, including Visa Credit, Visa Debit, Visa Electron, and V Pay cards, are affected by the security flaw, but the researchers posited it could apply to EMV protocols implemented by Discover and UnionPay as well. The loophole, however, doesn't impact Mastercard, American Express, and JC

The introduction of Open AI's ChatGPT was a defining moment for the software industry, touching off a GenAI race with its November 2022 release. SaaS vendors are now rushing to upgrade tools with enhanced productivity capabilities that are driven by generative AI. Among a wide range of uses, GenAI tools make it easier for developers to build software, assist sales teams in mundane email writing, help marketers produce unique content at low cost, and enable teams and creatives to brainstorm new ideas.  Recent significant GenAI product launches include Microsoft 365 Copilot, GitHub Copilot, and Salesforce Einstein GPT. Notably, these GenAI tools from leading SaaS providers are paid enhancements, a clear sign that no SaaS provider will want to miss out on cashing in on the GenAI transformation. Google will soon launch its SGE "Search Generative Experience" platform for premium AI-generated summaries rather than a list of websites.  At this pace, it's just a matter of a short time befo

An adversary known for targeting the fintech sector at least since 2018 has switched up its tactics to include a new Python-based remote access Trojan (RAT) that can steal passwords, documents, browser cookies, email credentials, and other sensitive information. In an analysis published by Cybereason researchers yesterday, the Evilnum group has not only tweaked its infection chain but has also deployed a Python RAT called "PyVil RAT," which possesses abilities to gather information, take screenshots, capture keystrokes data, open an SSH shell and deploy new tools. "Since the first reports in 2018 through today, the group's TTPs have evolved with different tools while the group has continued to focus on fintech targets," the cybersecurity firm said . "These variations include a change in the chain of infection and persistence, new infrastructure that is expanding over time, and the use of a new Python-scripted Remote Access Trojan (RAT)" to spy

An Iranian cyberespionage group known for targeting government, defense technology, military, and diplomacy sectors is now impersonating journalists to approach targets via LinkedIn and WhatsApp and infect their devices with malware. Detailing the new tactics of the "Charming Kitten" APT group, Israeli firm Clearsky said, "starting July 2020, we have identified a new TTP of the group, impersonating 'Deutsche Welle' and the 'Jewish Journal' using emails alongside WhatsApp messages as their main platform to approach the target and convince them to open a malicious link." This development is the first time the threat actor is said to have carried out a watering hole attack through WhatsApp and LinkedIn, which also includes making phone calls to victims, Clearsky noted in a Thursday analysis. After the company alerted Deutsche Welle about the impersonation and the watering hole in their website, the German broadcaster confirmed, "the repor

A notorious banking trojan aimed at stealing bank account credentials and other financial information has now come back with new tricks up its sleeve to target government, military, and manufacturing sectors in the US and Europe, according to new research. In an analysis released by Check Point Research today, the latest wave of Qbot activity appears to have dovetailed with the return of Emotet — another email-based malware behind several botnet-driven spam campaigns and ransomware attacks — last month, with the new sample capable of covertly gathering all email threads from a victim's Outlook client and using them for later malspam campaigns. "These days Qbot is much more dangerous than it was previously — it has an active malspam campaign which infects organizations, and it manages to use a 'third-party' infection infrastructure like Emotet's to spread the threat even further," the cybersecurity firm said . Using Hijacked Email Threads as Lures

Hackers always find a way in, even if there's no software vulnerability to exploit. The FBI has arrested a Russian national who recently traveled to the United States and offered $1 million in bribe to an employee of a targeted company for his help in installing malware into the company's computer network manually. Egor Igorevich Kriuchkov , 27-year-old, entered the United States as a tourist and was arrested in Los Angeles after meeting with the unnamed employee of an undisclosed Nevada-based company numerous times, between August 1 to August 21, to discuss the conspiracy. "On or about July 16, EGOR IGOREVICH KRIUCHKOV used his WhatsApp account to contact the employee of victim company and arranged to visit in person in the District of Nevada," the court documents say. "On or about July 28, EGOR IGOREVICH KRIUCHKOV entered the United States using his Russian Passport and a B1/B2 tourist visa." Kriuchkov also asked the employee to participate in

An unpatched security weakness in Google Drive could be exploited by malware attackers to distribute malicious files disguised as legitimate documents or images, enabling bad actors to perform spear-phishing attacks comparatively with a high success rate. The latest security issue—of which Google is aware but, unfortunately, left unpatched—resides in the " manage versions " functionality offered by Google Drive that allows users to upload and manage different versions of a file, as well as in the way its interface provides a new version of the files to the users. Logically, the manage versions functionally should allow Google Drive users to update an older version of a file with a new version having the same file extension, but it turns out that it's not the case. According to A. Nikoci, a system administrator by profession who reported the flaw to Google and later disclosed it to The Hacker News, the affected functionally allows users to upload a new version wit

The United States Cybersecurity and Infrastructure Security Agency (CISA) has published a new report warning companies about a new in-the-wild malware that North Korean hackers are reportedly using to spy on key employees at government contracting companies. Dubbed ' BLINDINGCAN ,' the advanced remote access trojan acts as a backdoor when installed on compromised computers. According to the FBI and CISA, North Korean state-sponsored hackers Lazarus Group , also known as Hidden Cobra , are spreading BLINDINGCAN to "gather intelligence surrounding key military and energy technologies." To achieve this, attackers first identify high-value targets, perform extensive research on their social and professional networks, and then pose as recruiters to send malicious documents loaded with the malware, masquerading as job advertisements and offerings. However, such employment scams and social engineering strategies are not new and were recently spotted being used in

The South African arm of one of the world's largest credit check companies Experian yesterday announced a data breach incident that exposed personal information of millions of its customers. While Experian itself didn't mention the number of affect customers, in a report , the South African Banking Risk Information Centre—an anti-fraud and banking non-profit organization who worked with Experian to investigate the breach—disclosed that the attacker had reportedly stolen data of 24 million South Africans and 793,749 business entities. Notably, according to the company, the suspected attacker behind this breach had already been identified, and the stolen data of its customers had successfully been deleted from his/her computing devices. "We have identified the suspect and confirm that Experian South Africa was successful in obtaining and executing an Anton Piller order which resulted in the individual's hardware being impounded and the misappropriated data being

Emotet, a notorious email-based malware behind several botnet-driven spam campaigns and ransomware attacks, contained a flaw that allowed cybersecurity researchers to activate a kill-switch and prevent the malware from infecting systems for six months. "Most of the vulnerabilities and exploits that you read about are good news for attackers and bad news for the rest of us," Binary Defense's James Quinn said. "However, it's important to keep in mind that malware is software that can also have flaws. Just as attackers can exploit flaws in legitimate software to cause harm, defenders can also reverse-engineer malware to discover its vulnerabilities and then exploit those to defeat the malware." The kill-switch was alive between February 6, 2020, to August 6, 2020, for 182 days, before the malware authors patched their malware and closed the vulnerability. Since its first identification in 2014, Emotet has evolved from its initial roots as a banking

A new research has identified four new variants of HTTP request smuggling attacks that work against various commercial off-the-shelf web servers and HTTP proxy servers. Amit Klein, VP of Security Research at SafeBreach who presented the findings today at the Black Hat security conference, said that the attacks highlight how web servers and HTTP proxy servers are still susceptible to HTTP request smuggling even after 15 years since they were first documented. What is HTTP Request Smuggling? HTTP request smuggling (or HTTP Desyncing) is a technique employed to interfere with the way a website processes sequences of HTTP requests that are received from one or more users. Vulnerabilities related to HTTP request smuggling typically arise when the front-end (a load balancer or proxy) and the back-end servers interpret the boundary of an HTTP request differently, thereby allowing a bad actor to send (or "smuggle") an ambiguous request that gets prepended to the next le

Intelligence agencies in the US have released information about a new variant of 12-year-old computer virus used by China's state-sponsored hackers targeting governments, corporations, and think tanks. Named " Taidoor, " the malware has done an 'excellent' job of compromising systems as early as 2008 , with the actors deploying it on victim networks for stealthy remote access. "[The] FBI has high confidence that Chinese government actors are using malware variants in conjunction with proxy servers to maintain a presence on victim networks and to further network exploitation," the US Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), and the Department of Defense (DoD) said in a joint advisory . The US Cyber Command has also uploaded four samples of the Taidoor RAT on the public malware repository VirusTotal to let 50+ Antivirus companies check the virus's involvement in other unattributed cam

The Council of the European Union has imposed its first-ever sanctions against persons or entities involved in various cyber-attacks targeting European citizens, and its member states. The directive has been issued against six individuals and three entities responsible for or involved in various cyber-attacks, out of which some publicly known are ' WannaCry ', ' NotPetya ', and ' Operation Cloud Hopper ,' as well as an attempted cyber-attack against the organization for the prohibition of chemical weapons. Out of the six individuals sanctioned by the EU include two Chinese citizens and four Russian nationals. The companies involved in carrying out cyberattacks include an export firm based in North Korea, and technology companies from China and Russia. The sanctions imposed include a ban on persons traveling to any EU countries and a freeze of assets on persons and entities. Besides this, EU citizens and entities are also forbidden from doing any busin

Cybersecurity researchers have discovered critical vulnerabilities in industrial VPN implementations primarily used to provide remote access to operational technology (OT) networks that could allow hackers to overwrite data, execute malicious code, and compromise industrial control systems (ICS). A new report published by industrial cybersecurity company Claroty demonstrates multiple severe vulnerabilities in enterprise-grade VPN installations, including Secomea GateManager M2M Server, Moxa EDR-G902, and EDR-G903, and HMS Networks eWon's eCatcher VPN client. These vulnerable products are widely used in field-based industries such as oil and gas, water utilities, and electric utilities to remotely access, maintain and monitor ICS and field devices, including programmable logic controllers (PLCs) and input/output devices. According to Claroty researchers, successful exploitation of these vulnerabilities can give an unauthenticated attacker direct access to the ICS devices an

Cybersecurity agencies in the US and UK yesterday issued a joint advisory about a massive ongoing malware threat infecting Taiwanese company QNAP's network-attached storage (NAS) appliances. Called QSnatch (or Derek), the data-stealing malware is said to have compromised 62,000 devices since reports emerged last October, with a high degree of infection in Western Europe and North America. "All QNAP NAS devices are potentially vulnerable to QSnatch malware if not updated with the latest security fixes," the US Cybersecurity and Infrastructure Security Agency (CISA) and the UK's National Cyber Security Centre (NCSC) said in the alert. "Further, once a device has been infected, attackers can prevent administrators from successfully running firmware updates." The mode of compromise, i.e., the infection vector, still remains unclear, but CISA and NCSC said the first campaign likely began in 2014 and continued till mid-2017 before intensifying over th

Garmin, the maker of fitness trackers, smartwatches and GPS-based wearable devices, is currently dealing with a massive worldwide service interruption after getting hit by a targeted ransomware attack, an employee of the company told The Hacker News on condition of anonymity. The company's website and the Twitter account say, "We are currently experiencing an outage that affects Garmin.com and Garmin Connect." "This outage also affects our call centers, and we are currently unable to receive any calls, emails or online chats. We are working to resolve this issue as quickly as possible and apologize for this inconvenience." As a result, the company yesterday was forced to temporarily shut down some of its connected services, including Garmin Express, Garmin Connect mobile, and the website—restricting millions of its users from accessing the cloud services or even syncing their watches locally to the app. Though not much information is available on tech

Cybersecurity researchers on Tuesday detailed as many as four different families of Brazilian banking trojans that have targeted financial institutions in Brazil, Latin America, and Europe. Collectively called the "Tetrade" by Kaspersky researchers, the malware families — comprising Guildma, Javali, Melcoz, and Grandoreiro — have evolved their capabilities to function as a backdoor and adopt a variety of obfuscation techniques to hide its malicious activities from security software. "Guildma, Javali, Melcoz and Grandoreiro are examples of yet another Brazilian banking group/operation that has decided to expand its attacks abroad, targeting banks in other countries," Kaspersky said in an analysis . "They benefit from the fact that many banks operating in Brazil also have operations elsewhere in Latin America and Europe, making it easy to extend their attacks against customers of these financial institutions."
