Google on Thursday rolled out an emergency update for its Chrome web browser, including fixes for two zero-day vulnerabilities that it says are being actively exploited in the wild. Tracked as  CVE-2021-38000  and  CVE-2021-38003 , the weaknesses relate to insufficient validation of untrusted input in a feature called Intents as well as a case of inappropriate implementation in V8 JavaScript and WebAssembly engine. The internet giant's Threat Analysis Group (TAG) has been credited with discovering and reporting the two flaws on September 15, 2021, and October 26, 2021, respectively. "Google is aware that exploits for CVE-2021-38000 and CVE-2021-38003 exist in the wild," the company  noted  in an advisory without delving into technical specifics about how the two vulnerabilities were used in attacks or the threat actors that may have weaponized them. Also addressed as part of this stable channel update is a  use-after-free  vulnerability in the Web...

Microsoft 365 (M365), formerly called Office 365 (O365), is Microsoft's cloud strategy flagship product with major changes ahead, such as the deprecation of their legacy authentication protocols. Often stored on or saved to the device, Basic Authentication protocols rely on sending usernames and passwords with every request, increasing the risk of attackers capturing users' credentials, particularly if not TLS protected. Basic Authentication, while necessary for companies using legacy software, is unable to enforce MFA and is superseded by Modern Authentication. The legacy settings have been on Microsoft's radar to fix for years. In 2018,  Microsoft announced  it would introduce a series of changes — and ultimately deprecation — to its authentication controls as a means to help organizations mitigate the risk. These changes were set to take place over a number of years, and in September 2021,  they announced  that they will begin to permanently disable Basic Auth ...

Over 70% of Wi-Fi networks from a sample size of 5,000 were hacked with "relative ease" in the Israeli city of Tel Aviv, highlighting how unsecure Wi-Fi passwords can become a gateway for serious threats to individuals, small businesses, and enterprises alike. CyberArk security researcher Ido Hoorvitch, who used a Wi-Fi sniffing equipment costing about $50 to collect 5,000 network hashes for the study,  said  "the process of sniffing Wi-Fis and the subsequent cracking procedures was a very accessible undertaking in terms of equipment, costs and execution." The new Wi-Fi attack builds on  previous findings  by Jens "atom" Steube in 2018 that involves capturing what's called the PMKIDs associated with a client (aka SSID) in order to attempt a brute-force attack using password recovery tools like hashcat. PMKID is a  unique key identifier  used by the access point (AP) to keep track of the pre-shared key — i.e., pairwise master key aka PMK — being u...

Cybersecurity researchers on Wednesday took the wraps off a "simple yet remarkable" malware loader for malicious Windows binaries targeting Central Europe, North America and the Middle East. Codenamed " Wslink " by ESET, this previously undocumented malware stands apart from the rest in that it runs as a server and executes received modules in memory. There are no specifics available on the initial compromise vector and there are no code or operational overlaps that tie this tool to a known threat actor group. The Slovak cybersecurity firm noted that it has seen only a handful of detections in the past two years, suggesting that it could be used in highly-targeted cyber infiltrations. Wslink is designed to run as a service and can accept encrypted portal executable (PE) files from a specific IP address, which is then decrypted and loaded into memory prior to the execution. To achieve this, the client (i.e., the victim) and the server perform a handshake that in...

Malicious actors have yet again published two more typosquatted libraries to the official NPM repository that mimic a legitimate package from Roblox, the game company, with the goal of distributing stealing credentials, installing remote access trojans, and infecting the compromised systems with ransomware. The bogus packages — named " noblox.js-proxy " and " noblox.js-proxies " — were found to impersonate a library called " noblox.js ," a Roblox game API wrapper available on NPM and boasts of nearly 20,000 weekly downloads, with each of the poisoned libraries, downloaded a total of 281 and 106 times respectively. According to Sonatype researcher Juan Aguirre, who  discovered  the malicious NPM packages, the author of noblox.js-proxy first published a benign version that was later tampered with the obfuscated text, in reality, a Batch (.bat) script, in the post-installation JavaScript file. This Batch script, in turn, downloads malicious executables ...

A new spam email campaign has emerged as a conduit for a previously undocumented malware loader that enables the attackers to gain an initial foothold into enterprise networks and drop malicious payloads on compromised systems. "These infections are also used to facilitate the delivery of additional malware such as Qakbot and Cobalt Strike, two of the most common threats regularly observed targeting organizations around the world,"  said  researchers with Cisco Talos in a technical write-up. The malspam campaign is believed to have commenced in mid-September 2021 via laced Microsoft Office documents that, when opened, triggers an infection chain that leads to the machines getting infected with a malware dubbed SQUIRRELWAFFLE . Mirroring a technique that's consistent with other phishing attacks of this kind, the latest operation leverages stolen email threads to give it a veil of legitimacy and trick unsuspecting users into opening the attachments. What's more, t...

One of the side effects of today's cyber security landscape is the overwhelming volume of data security teams must aggregate and parse. Lean security teams don't have it any easier, and the problem is compounded if they must do it manually. Data and log management are essential for organizations to gain real-time transparency and visibility into security events.  XDR provider Cynet has offered up a new guide ( read it here ) that helps lean organizations understand the importance of centralized log management (CLM). The truth is that even the most well-stocked and staffed teams would have trouble manually handling their log management needs, which is why organizations are increasingly going the automated route.  On top of the efficiency of automation, CLM gives organizations much greater visibility into their environment and security events that impact them. However, the benefits of deploying CLM tools and reducing the level of human intervention in log manageme...
