AI in cybersecurity: Yesterday’s promise, today’s reality

Posted by in categories: cybercrime/malcode, robotics/AI

For years, we’ve debated the benefits of artificial intelligence (AI) for society, but it wasn’t until now that people can finally see its daily impact. But why now? What changed that’s made AI in 2023 substantially more impactful than before?

First, consumer exposure to emerging AI innovations has elevated the subject, increasing acceptance. From songwriting and composing images in ways previously only imagined to writing college-level papers, generative AI has made its way into our everyday lives. Second, we’ve also reached a tipping point in the maturity curve for AI innovations in the enterprise—and in the cybersecurity industry, this advancement can’t come fast enough.

If your Laptop or PC has Gigabyte motherboard then it has backdoor for hackers

Posted by in categories: cybercrime/malcode, internet

Researchers at the cybersecurity firm Eclypsium, which focuses on firmware, reported today that they have found a secret backdoor in the firmware of motherboards manufactured by the Taiwanese manufacturer Gigabyte’s components are often used in gaming PCs and other high-performance systems. Eclypsium discovered that whenever a computer with the affected Gigabyte motherboard restarts, code inside the motherboard’s firmware silently triggers the launch of an updater application, which then downloads and runs another piece of software on the machine. Researchers discovered that the hidden code was built in an unsafe manner, making it possible for the mechanism to be hijacked and used to install malware rather than Gigabyte’s intended software.

Despite the fact that Eclypsium claims the hidden code is intended to be a harmless utility to keep the motherboard’s firmware updated, researchers determined that the implementation was vulnerable. And since the updater application is activated from the computer’s firmware rather than the operating system, it is difficult for users to either delete it or even detect it on their own. In the blog post, the company details the 271 different versions of Gigabyte motherboards that the researchers think are vulnerable. According to experts, individuals who are interested in discovering the motherboard that is used by their computer may do so by selecting “Start” in Windows and then selecting “System Information.”

Users who don’t trust Gigabyte to silently install code on their machine with a nearly invisible tool may have been concerned by Gigabyte’s updater alone. Other users may have been concerned that Gigabyte’s mechanism could be exploited by hackers who compromise the motherboard manufacturer to exploit its hidden access in a software supply chain attack. The update process was designed and built with obvious flaws that left it susceptible to being exploited in the following ways: It downloads code to the user’s workstation without properly authenticating it, and in certain cases, it even does it through an unsecured HTTP connection rather than an HTTPS one. This would make it possible for a man-in-the-middle attack to be carried out by anybody who is able to intercept the user’s internet connection, such as a malicious Wi-Fi network. The attack would enable the installation source to be faked.

New phishing technique to allows hacking someone using.zip &.mov domains

Posted by in category: cybercrime/malcode

When a victim visits a website ending in. ZIP, a recently developed phishing method known as “file archiver in the browser” may be used to “emulate” file-archiving software in the target’s web browser.

According to information published by a security researcher named mr.d0x last week, “with this phishing attack, you simulate a file archiver software (e.g., WinRAR) in the browser and use a.zip domain to make it appear more legitimate,”

In a nutshell, threat actors could develop a realistic-looking phishing landing page using HTML and CSS that replicates genuine file archiving software. They could then host the website on a.zip domain, which would elevate social engineering tactics to a higher level.

CAPTCHA-Breaking Services with Human Solvers Helping Cybercriminals Defeat Security

Posted by in categories: cybercrime/malcode, food, robotics/AI

Cybersecurity researchers are warning about CAPTCHA-breaking services that are being offered for sale to bypass systems designed to distinguish legitimate users from bot traffic.

“Because cybercriminals are keen on breaking CAPTCHAs accurately, several services that are primarily geared toward this market demand have been created,” Trend Micro said in a report published last week.

“These CAPTCHA-solving services don’t use [optical character recognition] techniques or advanced machine learning methods; instead, they break CAPTCHAs by farming out CAPTCHA-breaking tasks to actual human solvers.”

Critical Firmware Vulnerability in Gigabyte Systems Exposes ~7 Million Devices

Posted by in category: cybercrime/malcode

Cybersecurity researchers have found “backdoor-like behavior” within Gigabyte systems, which they say enables the UEFI firmware of the devices to drop a Windows executable and retrieve updates in an unsecure format.

Firmware security firm Eclypsium said it first detected the anomaly in April 2023. Gigabyte has since acknowledged and addressed the issue.

“Most Gigabyte firmware includes a Windows Native Binary executable embedded inside of the UEFI firmware,” John Loucaides, senior vice president of strategy at Eclypsium, told The Hacker News.

New ‘Lobshot’ hVNC Malware Used by Russian Cybercriminals

Posted by in category: cybercrime/malcode

Russian cybercrime group TA505 has been observed using new hVNC (Hidden Virtual Network Computing) malware in recent attacks, threat intelligence company Elastic reports.

Called Lobshot, the malware allows attackers to bypass fraud detection engines and provides them with stealthy, direct access to the infected machines.

The threat actor distributes the malware through malvertising, abusing Google Ads and a network of fake websites to trick users into downloading legitimate-looking installers containing backdoors.

Why do people become ethical hackers? Given the negative connotations that the word “hacker” has unfortunately acquired over the past few decades, it’s tough to understand why anyone would ascribe themselves to that oxymoron.

Yet, ethical hackers are playing an increasingly vital role in cybersecurity, and the ranks of the ethical hacking community are growing significantly. If you’re thinking about working with or hiring ethical hackers — or even becoming one yourself — it’s important to understand what makes this unique breed of cyber-pro tick.

Critical Flaw in Inea ICS Product Exposes Industrial Organizations to Remote Attacks

Posted by in categories: cybercrime/malcode, robotics/AI

A critical vulnerability found in a remote terminal unit (RTU) made by Slovenia-based industrial automation company Inea can expose industrial organizations to remote hacker attacks.

The existence of the vulnerability came to light last week, when the US Cybersecurity and Infrastructure Security Agency (CISA) published an advisory to inform organizations. The vendor has released a firmware update that patches the issue.

The security hole, tracked as CVE-2023–2131 with a CVSS score of 10, impacts Inea ME RTUs running firmware versions prior to 3.36. This OS command injection bug could allow remote code execution, CISA said.
