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.

Irrigation Systems in Israel Disrupted

Posted by in categories: cybercrime/malcode, food, sustainability

Automated irrigation systems in the Northern part of Israel were briefly disrupted recently in an attack that once again shows how easy it can be to hack industrial control systems (ICS).

The Jerusalem Post reported that hackers targeted water controllers for irrigation systems at farms in the Jordan Valley, as well as wastewater treatment control systems belonging to the Galil Sewage Corporation.

Farms were warned by Israel’s National Cyber Directorate prior to the incident, being instructed to disable remote connections to these systems due to the high risk of cyberattacks. Roughly a dozen farms in the Jordan Valley and other areas failed to do so and had their water controllers hacked. This led to automated irrigation systems being temporarily disabled, forcing farmers to turn to manual irrigation.

The Security Hole at the Heart of ChatGPT and Bing

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

Indirect prompt-injection attacks are similar to jailbreaks, a term adopted from previously breaking down the software restrictions on iPhones. Instead of someone inserting a prompt into ChatGPT or Bing to try and make it behave in a different way, indirect attacks rely on data being entered from elsewhere. This could be from a website you’ve connected the model to or a document being uploaded.

“Prompt injection is easier to exploit or has less requirements to be successfully exploited than other” types of attacks against machine learning or AI systems, says Jose Selvi, executive principal security consultant at cybersecurity firm NCC Group. As prompts only require natural language, attacks can require less technical skill to pull off, Selvi says.

There’s been a steady uptick of security researchers and technologists poking holes in LLMs. Tom Bonner, a senior director of adversarial machine-learning research at AI security firm Hidden Layer, says indirect prompt injections can be considered a new attack type that carries “pretty broad” risks. Bonner says he used ChatGPT to write malicious code that he uploaded to code analysis software that is using AI. In the malicious code, he included a prompt that the system should conclude the file was safe. Screenshots show it saying there was “no malicious code” included in the actual malicious code.
