Cybersecurity researchers are warning about an ongoing Android malware campaign that has been active since 2016 and was first publicly reported in August 2018. Dubbed " ViceLeaker " by researchers at Kaspersky, the campaign has recently been found targeting Israeli citizens and some other middle eastern countries with a powerful surveillance malware designed to steal almost all accessible information, including call recordings, text messages, photos, videos, and location data—all without users' knowledge. Besides these traditional spying functionalities, the malware also has backdoor capabilities including upload, download, and delete files, record surrounding audio, takeover camera, and make calls or send messages to specific numbers. The malware used in these campaigns was named " Triout " in a report published by Bitdefender in 2018, which is sort of a malware framework that attackers are using to turn legitimate applications into spyware by inject...

Microsoft has introduced a new password-protected folder within its OneDrive online file storage service that will allow you to keep your sensitive and important files protected and secured with an extra layer of authentication. Dubbed Personal Vault , the new OneDrive folder can only be accessed with an additional step of identity verification, such as your fingerprint, face, PIN, or a two-factor authentication code sent to you via email or SMS. The Personal Vault folder will appear next to other folders in the OneDrive app like your Documents and Pictures, but it will be locked and prompt you for an additional code each time you try to access them via the web, PC, or mobile devices, thus keeping them more secure in the event when someone gains access to your account or your device. Microsoft suggests this new protected area in OneDrive would be useful for users to store more sensitive and personal files like copies of passport, tax, car or home documents, identification cards,...

Cybersecurity researchers from Intego are warning about possible active exploitation of an unpatched security vulnerability in Apple's macOS Gatekeeper security feature details and PoC for which were publicly disclosed late last month. Intego team last week discovered four samples of new macOS malware on VirusTotal that leverage the GateKeeper bypass vulnerability to execute untrusted code on macOS without displaying users any warning or asking for their explicit permission. However, the newly discovered malware, dubbed OSX/Linker , has not been seen in the wild as of now and appears to be under development. Though the samples leverage unpatched Gatekeeper bypass flaw, it does not download any malicious app from the attacker's server. According to Joshua Long from Intego, until last week, the "malware maker was merely conducting some detection testing reconnaissance." "One of the files was signed with an Apple Developer ID (as explained below), it is ...

In recent years, several groups of cybersecurity researchers have disclosed dozens of memory side-channel vulnerabilities in modern processors and DRAM s, like Rowhammer , RAMBleed , Spectre, and Meltdown . Have you ever noticed they all had at least one thing in common? That's OpenSSH. As a proof-of-concept, many researchers demonstrated their side-channel attacks against OpenSSH application installed on a targeted computer, where an unprivileged attacker-owned process exploits memory read vulnerabilities to steal secret SSH private keys from the restricted memory regions of the system. That's possible because OpenSSH has an agent that keeps a copy of your SSH key in the memory so that you don't have to type your passphrase every time you want to connect to the same remote server. However, modern operating systems by default store sensitive data, including encryption keys and passwords, in the kernel memory which can not be accessed by user-level privileged p...

As we reported two days ago, Microsoft this week released an updated version of its Outlook app for Android that patches a severe remote code execution vulnerability ( CVE-2019-1105 ) that impacted over 100 million users. However, at that time, very few details of the flaw were available in the advisory, which just revealed that the earlier versions of the email app contained a cross-site scripting (XSS) flaw that could allow attackers to run scripts in the context of the current user just by sending a specially crafted email to the victims. Now, Bryan Appleby from F5 Networks, one of the security researchers who reported this issue independently to Microsoft, released more details and proof-of-concept for the Outlook vulnerability that he reported to the tech giant almost six months ago. In a blog post published Friday, Appleby revealed that while exchanging some JavaScript code with his friends over an email, he accidentally discovered a cross-site scripting (XSS) issue th...

If you use VLC media player on your computer and haven't updated it recently, don't you even dare to play any untrusted, randomly downloaded video file on it. Doing so could allow hackers to remotely take full control over your computer system. That's because VLC media player software versions prior to 3.0.7 contain two high-risk security vulnerabilities , besides many other medium- and low-severity security flaws, that could potentially lead to arbitrary code execution attacks. With more than 3 billion downloads, VLC is a hugely popular open-source media player software that is currently being used by hundreds of millions of users worldwide on all major platforms, including Windows, macOS, Linux, as well as Android and iOS mobile platforms. Discovered by Symeon Paraschoudis from Pen Test Partners and identified as CVE-2019-12874 , the first high-severity vulnerability is a double-free issue which resides in "zlib_decompress_extra" function of VideoLAN ...

Cybersecurity researchers from at least two firms today unveiled details of a new strain of malware that targets Windows and macOS systems with a Linux-based cryptocurrency mining malware. It may sound strange, but it's true. Dubbed " LoudMiner " and also " Bird Miner, " the attack leverages command-line based virtualization software on targeted systems to silently boot an image of Tiny Core Linux OS that already contains a hacker-activated cryptocurrency mining software in it. Isn't it interesting to use emulation to run single-platform malware on cross-platforms? Spotted by researchers at ESET and Malwarebytes , attackers are distributing this malware bundled with pirated and cracked copies of VST (Virtual Studio Technology) software on the Internet and via Torrent network since August 2018. VST applications contain sounds, effects, synthesizers, and other advanced editing features that allow tech-centric audio professionals to create music. ...

Okay, folks, it's time to update your Firefox web browser once again—yes, for the second time this week. After patching a critical actively-exploited vulnerability in Firefox 67.0.3 earlier this week, Mozilla is now warning millions of its users about a second zero-day vulnerability that attackers have been found exploiting in the wild. The newly patched issue ( CVE-2019-11708 ) is a "sandbox escape" vulnerability, which if chained together with the previously patched "type confusion" bug ( CVE-2019-11707 ), allows a remote attacker to execute arbitrary code on victims' computers just by convincing them into visiting a malicious website. Browser sandboxing is a security mechanism that keeps third-party processes isolated and confined to the browser, preventing them from damaging other sensitive parts of a computer's operating system. "Insufficient vetting of parameters passed with the Prompt:Open IPC message between child and parent proc...

Dell's SupportAssist utility that comes pre-installed on millions of Dell laptops and PCs contains a security vulnerability that could allow malicious software or rogue logged-in users to escalate their privileges to administrator-level and access sensitive information. Discovered by security researchers at SafeBreach Labs , the vulnerability, identified as CVE-2019-12280, is a privilege-escalation issue and affects Dell's SupportAssist application for business PCs (version 2.0) and home PCs (version 3.2.1 and all prior versions). Dell SupportAssist, formerly known as Dell System Detect, checks the health of your system's hardware and software, alerting customers to take appropriate action to resolve them. To do so, it runs on your computer with SYSTEM-level permissions. With this high-level privileges, the utility interacts with the Dell Support website and automatically detects Service Tag or Express Service Code of your Dell product, scans the existing device d...

Update (22 June 2019)  — More technical details and proof-of-concept for the OutLook for Android vulnerability has been released that we have covered in a separate article here. Microsoft today released an updated version of its "Outlook for Android" that patches an important security vulnerability in the popular email app that is currently being used over 100 million users. According to an advisory , Outlook app with versions before 3.0.88 for Android contains a stored cross-site scripting vulnerability ( CVE-2019-1105 ) in the way the app parses incoming email messages. If exploited, remote attackers can execute malicious in-app client-side code on the targeted devices just by sending them emails with a specially crafted message. "The attacker who successfully exploited this vulnerability could then perform cross-site scripting attacks on the affected systems and run scripts in the security context of the current user." According to Microsoft, the fl...

At its developer conference held earlier this week in New York, the MongoDB team announced the latest version of its database management software that includes a variety of advanced features, including Field Level Encryption, Distributed Transactions, and Wildcard Indexes. The newly introduced Field Level Encryption (FLE), which will be available in the upcoming MongoDB 4.2 release, is an end-to-end encryption feature that encrypts and decrypts sensitive users' data on the client-side, preventing hackers from accessing plaintext data even if the database instance left exposed online or the server itself gets compromised. Almost every website, app, and service on the Internet today usually encrypt (particularly "hashing") only users' passwords before storing them into the databases, but unfortunately left other sensitive information unencrypted, including users' online activity data and their personal information. Moreover, even if there is an encryption...

Important Update (21 June 2019) ➤  The Tor Project on Friday released second update ( Tor Browser 8.5.3 ) for its privacy web-browser that patches the another Firefox zero-day vulnerability patched this week. Following the latest critical update for Firefox, the Tor Project today released an updated version of its anonymity and privacy browser to patch the same Firefox vulnerability in its bundle. Earlier this week, Mozilla released Firefox 67.0.3 and Firefox ESR 60.7.1 versions to patch a critical actively-exploited vulnerability ( CVE-2019-11707 ) that could allow attackers to remotely take full control over systems running the vulnerable browser versions. Besides updating Firefox, the latest Tor Browser 8.5.2 for desktops also includes updated NoScript version 10.6.3 that fixes a few known issues. According to the Tor Project Team, if you are already using Tor browser with "safer" and "safest" security levels, the flaw doesn't affect you. For som...
