Almost 10 days after application security company F5 Networks released patches for critical vulnerabilities in its BIG-IP and BIG-IQ products, adversaries have begun opportunistically mass scanning and targeting exposed and unpatched networking devices to break into enterprise networks. News of in the wild exploitation development comes on the heels of a proof-of-concept exploit code that

Privacy-focused search engine DuckDuckGo called out rival Google for “spying” on users after the search giant updated its flagship app to spell out the exact kinds of information it collects for personalization and marketing purposes. “After months of stalling, Google finally revealed how much personal data they collect in Chrome and the Google app. No

A newly discovered glitch in Zoom’s screen sharing feature can accidentally leak sensitive information to other attendees in a call, according to the latest findings. Tracked as CVE-2021-28133, the unpatched security vulnerability makes it possible to reveal contents of applications that are not shared, but only briefly, thereby making it harder to exploit it in

Cybersecurity researchers on Thursday disclosed a new attack wherein threat actors are leveraging Xcode as an attack vector to compromise Apple platform developers with a backdoor, adding to a growing trend that involves targeting developers and researchers with malicious attacks. Dubbed “XcodeSpy,” the trojanized Xcode project is a tainted version of a legitimate, open-source project

The U.S. Department of Justice yesterday announced updates on two separate cases involving cyberattacks—a Swiss hacktivist and a Russian hacker who planned to plant malware in the Tesla company. A Swiss hacker who was involved in the intrusion of cloud-based surveillance firm Verkada and exposed camera footage from its customers was charged by the U.S.

Are you looking to becoming a malware analyst? Then continue reading to discover how to gain the training you need and start a career in malware analysis career. Did you know that new malware is released every seven seconds? As more and more systems become reliant on the internet, the proliferation of malware becomes increasingly

A pair of critical vulnerabilities in a popular bulletin board software called MyBB could have been chained together to achieve remote code execution (RCE) without the need for prior access to a privileged account. The flaws, which were discovered by independent security researchers Simon Scannell and Carl Smith, were reported to the MyBB Team on

When a user account becomes locked out, the cause is often attributed to a user who has simply entered an old or incorrect password too many times. However, this is far from being the only thing that can cause an account to become locked. Another common cause, for example, is an application or script that

A Florida teen accused of masterminding the hacks of several high-profile Twitter accounts last summer as part of a widespread cryptocurrency scam pled guilty to fraud charges in exchange for a three-year prison sentence. Graham Ivan Clark, 18, will also serve an additional three years on probation. The development comes after the U.S. Department of

It’s not every day that one of the best-known independent cybersecurity individuals joins a cybersecurity company. The two are generally on opposite sides of the coin, with little crossover. After all, they’re usually concerned with different parts of the cybersecurity puzzle – one providing platforms and tools to defend organizations, the other keeping them accountable

Email security firm Mimecast on Tuesday revealed that the state-sponsored SolarWinds hackers who broke into its internal network also downloaded source code out of a limited number of repositories. “The threat actor did access a subset of email addresses and other contact information and hashed and salted credentials,” the company said in a write-up detailing

Microsoft on Monday released a one-click mitigation software that applies all the necessary countermeasures to secure vulnerable environments against the ongoing widespread ProxyLogon Exchange Server cyberattacks. Called Exchange On-premises Mitigation Tool (EOMT), the PowerShell-based script serves to mitigate against current known attacks using CVE-2021-26855, scan the Exchange Server using the Microsoft Safety Scanner for any

Cybersecurity researchers on Monday disclosed a new wave of ongoing attacks exploiting multiple vulnerabilities to deploy Mirai variants on compromised systems. “Upon successful exploitation, the attackers try to download a malicious shell script, which contains further infection behaviors such as downloading and executing Mirai variants and brute-forcers,” Palo Alto Networks’ Unit 42 Threat Intelligence Team

The U.S. Department of Justice (DoJ) on Friday announced an indictment against Jean-Francois Eap, the CEO of encrypted messaging company Sky Global, and an associate for wilfully participating in a criminal enterprise to help international drug traffickers avoid law enforcement.
