Since the past few weeks, software giant Citrix has privately been rolling out a critical software update to its enterprise customers that patches multiple security vulnerabilities affecting Citrix ShareFile content collaboration platform. The security advisory—about which The Hacker News learned from Dimitri van de Giessen , an ethical hacker and system engineer—is scheduled to be available publicly later today on the Citrix website . Citrix ShareFile is an enterprise-level file sharing solution for businesses using which employees can securely exchange proprietary and sensitive business data with each other. The software offers an on-premises secure cloud environment for data storage with auditing capabilities and regulatory compliance controls. For example, a company can remotely lock or wipe data from potentially compromised mobile devices, or they're when lost or stolen. The newly identified security issues ( CTX-CVE-2020-7473 ) specifically affect customer-managed o...

If you own a Xiaomi smartphone or have installed the Mi browser app on any of your other brand Android device, you should enable a newly introduced privacy setting immediately to prevent the company from spying on your online activities. The smartphone maker has begun rolling out an update to its Mi Browser/Mi Browser Pro (v12.1.4) and Mint Browser (v3.4.3) after concerns were raised over its practice of transmitting web browsing histories and device metadata to the company servers. The new privacy setting now allows Mi Browser users to disable aggregated data collection feature while in Incognito Mode, but it bears noting that it's not enabled by default. The option can be accessed by tapping the settings icon in the browser > Incognito mode settings > and then disable 'Enhanced incognito mode,' as shown in an attached screenshot below. Mint Browser and Mi Browser Pro have been downloaded more than 15 million times from Google Play to date. The devel...

Cybersecurity researcher Mordechai Guri from Israel's Ben Gurion University of the Negev recently demonstrated a new kind of malware that could be used to covertly steal highly sensitive data from air-gapped and audio-gapped systems using a novel acoustic quirk in power supply units that come with modern computing devices. Dubbed ' POWER-SUPPLaY ,' the latest research builds on a series of techniques leveraging electromagnetic, acoustic, thermal, optical covert channels, and even power cables to exfiltrate data from non-networked computers. "Our developed malware can exploit the computer power supply unit (PSU) to play sounds and use it as an out-of-band, secondary speaker with limited capabilities," Dr. Guri outlined in a paper published today and shared with The Hacker News. "The malicious code manipulates the internal switching frequency of the power supply and hence controls the sound waveforms generated from its capacitors and transformers....

Days after cybersecurity researchers sounded the alarm over two critical vulnerabilities in the SaltStack configuration framework , a hacking campaign has already begun exploiting the flaws to breach servers of LineageOS, Ghost, and DigiCert. Tracked as CVE-2020-11651 and CVE-2020-11652 , the disclosed flaws could allow an adversary to execute arbitrary code on remote servers deployed in data centers and cloud environments. The issues were fixed by SaltStack in a release published on April 29th. "We expect that any competent hacker will be able to create 100% reliable exploits for these issues in under 24 hours," F-Secure researchers had previously warned in an advisory last week. LineageOS, a maker of an open-source operating system based on Android, said it detected the intrusion on May 2nd at around 8 pm Pacific Time. "Around 8 pm PST on May 2nd, 2020, an attacker used a CVE in our SaltStack master to gain access to our infrastructure," the company n...

Two severe security flaws have been discovered in the open-source SaltStack Salt configuration framework that could allow an adversary to execute arbitrary code on remote servers deployed in data centers and cloud environments. The vulnerabilities were identified by F-Secure researchers earlier this March and disclosed on Thursday, a day after SaltStack released a patch (version 3000.2) addressing the issues , rated with CVSS score 10. "The vulnerabilities, allocated CVE IDs CVE-2020-11651 and CVE-2020-11652 , are of two different classes," the cybersecurity firm said . "One being authentication bypass where functionality was unintentionally exposed to unauthenticated network clients, the other being directory traversal where untrusted input (i.e., parameters in network requests) was not sanitized correctly allowing unconstrained access to the entire filesystem of the master server." The researchers warned that the flaws could be exploited in the wild imm...

In the last few months, multiple groups of attackers successfully compromised corporate email accounts of at least 156 high-ranking officers at various firms based in Germany, the UK, Netherlands, Hong Kong, and Singapore. Dubbed ' PerSwaysion ,' the newly spotted cyberattack campaign leveraged Microsoft file-sharing services—including Sway, SharePoint, and OneNote—to launch highly targeted phishing attacks. According to a report Group-IB Threat Intelligence team published today and shared with The Hacker News, PerSwaysion operations attacked executives of more than 150 companies around the world, primarily with businesses in finance, law, and real estate sectors. "Among these high-ranking officer victims, more than 20 Office365 accounts of executives, presidents, and managing directors appeared." So far successful and still ongoing, most PerSwaysion operations were orchestrated by scammers from Nigeria and South Africa who used a Vue.js JavaScript framewor...

A new type of mobile banking malware has been discovered abusing Android's accessibility features to exfiltrate sensitive data from financial applications, read user SMS messages, and hijack SMS-based two-factor authentication codes. Called "EventBot" by Cybereason researchers, the malware is capable of targeting over 200 different financial apps, including banking, money transfer services, and crypto-currency wallets such as Paypal Business, Revolut, Barclays, CapitalOne, HSBC, Santander, TransferWise, and Coinbase. "EventBot is particularly interesting because it is in such early stages," the researchers said. "This brand new malware has real potential to become the next big mobile malware, as it is under constant iterative improvements, abuses a critical operating system feature, and targets financial applications." The campaign, first identified in March 2020, masks its malicious intent by posing as legitimate applications (e.g., Adobe Fl...

The Scouts acknowledged the necessity to "Be Prepared" over 100 years (!) ago; the industry should have, as well. Yet COVID-19 took businesses – more like the entire world – by surprise. Very few were prepared for the explosion of remote access, and the challenge of instantly shifting an entire organization to work from anywhere. Cato Networks shared its increase in remote access usage post coronavirus outbreak. The trend is clear. Remote access has become an essential pillar for ensuring business continuity; nevertheless, the requirements to enable this, especially at a time of crisis, can be overwhelming. The industry is undergoing a paradigm shift. In the past, most works were performed from the office, and only a subset of the business operated remotely. Today, most (if not all) users require secure and optimized access to applications from remote. Legacy VPN isn't suited to support this shift. It was designed for sporadic access by a subset of the us...

Security researchers are sounding the alarm over newly discovered vulnerabilities in some popular online learning management system ( LMS ) plugins that various organizations and universities use to offer online training courses through their WordPress-based websites. According to the Check Point Research Team, the three WordPress plugins in question — LearnPress , LearnDash , and LifterLMS — have security flaws that could permit students, as well as unauthenticated users, to pilfer personal information of registered users and even attain teacher privileges. "Because of coronavirus, we're doing everything from our homes, including our formal learning," Check Point Research's Omri Herscovici said. "The vulnerabilities found allow students, and sometimes even unauthenticated users, to gain sensitive information or take control of the LMS platforms." The three LMS systems are installed on approximately 100,000 different educational platforms, includi...

It's not 'Patch Tuesday,' but software giant Adobe today released emergency updates for three of its widely used products that patch dozens of newly discovered critical vulnerabilities. The list of affected software includes Adobe Illustrator, Adobe Bridge, and Magento e-commerce platform, containing a total of 35 vulnerabilities where each one of them is affected with multiple critical arbitrary code execution flaws. According to security advisory Adobe released, Illustrator 2020—one of the most popular designing software with millions of users around the globe—contains 5 critical code execution flaw, all existed due to memory corruption bugs in the Windows version of the software.

Researchers have uncovered a potential means to profile and track online users using a novel approach that combines device identifiers with their biometric information. The details come from a newly published research titled "Nowhere to Hide: Cross-modal Identity Leakage between Biometrics and Devices" by a group of academics from the University of Liverpool, New York University, The Chinese University of Hong Kong, and University at Buffalo SUNY. "Prior studies on identity theft only consider the attack goal for a single type of identity, either for device IDs or biometrics," Chris Xiaoxuan Lu, Assistant Professor at the University of Liverpool, told The Hacker News in an email interview. "The missing part, however, is to explore the feasibility of compromising the two types of identities simultaneously and deeply understand their correlation in multi-modal IoT environments." The researchers presented the findings at the Web Conference 2020 held...

Microsoft has patched a worm-like vulnerability in its Teams workplace video chat and collaboration platform that could have allowed attackers to take over an organization's entire roster of Teams accounts just by sending participants a malicious link to an innocent-looking image. The flaw, impacting both desktop and web versions of the app, was discovered by cybersecurity researchers at CyberArk. After the findings were responsibly disclosed on March 23, Microsoft patched the vulnerability in an update released on April 20. "Even if an attacker doesn't gather much information from a Teams' account, they could still use the account to traverse throughout an organization (just like a worm)," CyberArk's Omer Tsarfati said. "Eventually, the attacker could access all the data from your organization's Teams accounts — gathering confidential information, meetings and calendar information, competitive data, secrets, passwords, private information, ...

Cybersecurity researchers from ESET on Thursday said they took down a portion of a malware botnet comprising at least 35,000 compromised Windows systems that attackers were secretly using to mine Monero cryptocurrency. The botnet, named "VictoryGate," has been active since May 2019, with infections mainly reported in Latin America, particularly Peru accounting for 90% of the compromised devices. "The main activity of the botnet is mining Monero cryptocurrency," ESET said . "The victims include organizations in both public and private sectors, including financial institutions." ESET said it worked with dynamic DNS provider No-IP to take down the malicious command-and-control (C2) servers and that it set up fake domains (aka sinkholes) to monitor the botnet's activity. The sinkhole data shows that between 2,000 and 3,500 infected computers connected to the C2 servers on a daily basis during February and March this year. According to ESET res...

In a recent highly targeted BEC attack, hackers managed to trick three British private equity firms into wire-transferring a total of $1.3 million to the bank accounts fraudsters have access to — while the victimized executives thought they closed an investment deal with some startups. According to the cybersecurity firm Check Point, who shared its latest investigation with The Hacker News, nearly $700,000 of the total wire transferred amount has permanently lost to the attackers, with the rest of the amount recovered after researchers alerted the targeted firms in time. Dubbed ' The Florentine Banker ,' the sophisticated cybercrime gang behind this attack, "seems to have honed their techniques over multiple attacks, from at least several years of activity and has proven to be a resourceful adversary, quickly adapting new situations," the researchers said. 'The techniques they use, especially the lookalike domains technique, present a severe threat — not ...
