This Week’s Top 5 Cybersecurity News Stories October 2024 | 02

Cybersecurity threats are evolving constantly as threat actors look to gain access to your data and money. To help you stay secure, we have searched the internet for the top five cybersecurity news stories of the week that we think you should be aware of.  No story is too big or small, as we look at threats from espionage to security flaws in every day devices:

1. Microsoft Reveals macOS Vulnerability that Bypasses Privacy Controls in Safari Browser

Microsoft has disclosed a vulnerability in Apple’s macOS Transparency, Consent, and Control (TCC) framework, tracked as CVE-2024-44133, which bypassed privacy controls in Safari. The flaw, dubbed “HM Surf,” allowed unauthorized access to sensitive data, such as camera, microphone, and location services, without user consent by manipulating local configuration files.

Apple patched the issue in macOS Sequoia 15, but Microsoft observed potential exploitation through the AdLoad macOS adware. The discovery highlights ongoing security challenges, especially in macOS environments with entitlements like those granted to Safari.

2. Researchers Uncover Cicada3301 Ransomware Operations and Its Affiliate Program

Researchers have uncovered Cicada3301, a ransomware-as-a-service (RaaS) operation, noted for its cross-platform capabilities, affecting devices running Windows, Linux, and more.

The group, linked to the now-defunct BlackCat ransomware, has compromised at least 30 organizations in critical sectors, primarily in the U.S. and U.K. Cicada3301 uses advanced encryption (ChaCha20 + RSA) and features an affiliate program, recruiting penetration testers and access brokers with a 20% commission. The ransomware shuts down virtual machines, deletes shadow copies, and encrypts network shares, maximizing the impact of its attacks.

3. U.S. Charges Two Sudanese Brothers for Record 35,000 DDoS Attacks

Two Sudanese brothers, Ahmed Salah Yousif Omer and Alaa Salah Yusuuf Omer, were charged by U.S. authorities for orchestrating a record 35,000 distributed denial-of-service (DDoS) attacks within a year. The attacks, linked to the group Anonymous Sudan, targeted critical infrastructure and businesses globally, including Microsoft services.

The brothers operated a DDoS-for-hire botnet using a tool named Distributed Cloud Attack Tool (DCAT), causing over $10 million in damages. If convicted, Ahmed Salah faces a life sentence, while Alaa Salah could face up to five years in prison.

4. Hacking Laptop With a BBQ Lighter to Gain Root Access

Hardware researcher David Buchanan used a BBQ lighter to exploit laptop vulnerabilities via electromagnetic fault injection (EMFI). Targeting the DDR bus in a Samsung S3520 laptop, Buchanan induced memory errors by manipulating data lines with electromagnetic interference.

This led to two proof-of-concept attacks: a CPython sandbox escape and a Linux local privilege escalation (LPE), enabling unprivileged users to gain root access by corrupting memory. The LPE exploit successfully modified system files and spawned a root shell, with a 20-50% success rate. This research underscores the risks of physical access to hardware and vulnerabilities in memory systems.

5. Talos warns of Russian-speaking hackers attacking Ukrainian and Polish companies

Russian-speaking hackers are launching cyberattacks against Ukraine and Poland, according to a report by Cisco Talos. The group, which is likely state-sponsored, is using phishing campaigns and custom malware to target organizations in sectors like transportation, logistics, and government.

These attacks coincide with the ongoing geopolitical tensions in the region, particularly related to the war in Ukraine. Talos has linked the group to previously identified threat actors, including Gamaredon and Sandworm, known for their sophisticated tactics. The attacks aim to disrupt operations and gather intelligence, underscoring the ongoing cybersecurity threats in Eastern Europe.
