Data protection advancements expected to shape 2025 security

Andrew Eva, the Global CIO of Assured Data Protection, predicts that by 2025, there will be a seamless integration of backup systems with ransomware detection, antivirus technologies, and intrusion detection systems. He highlights a collaboration between Rubrik and Google to provide enterprise customers with insights into known exploits for better early detection of malicious codes. Disaster recovery systems will take on a more frontline role in cyber threat management, utilizing machine learning to identify potential viruses. Ransomware is expected to remain the top cyber threat, prompting organizations to prioritize disaster recovery and backup solutions. Concerns about data security in relation to artificial intelligence will lead organizations to seek assurances regarding data protection from managed service providers (MSPs). The criteria for cyber insurance are tightening, making MSPs essential for businesses to meet these requirements. There is also an anticipated surge in demand for Backup-as-a-Service (BaaS), especially in healthcare, driven by resource constraints and a shift towards operational expenditures.

“I went through hell” Japanese indie dev on how their game was wrongly flagged as a virus, and blocked on Steam

A Japanese indie developer, Shiromofu Factory, launched the game Dungeon Antiqua on October 10, 2024. The game, inspired by early Final Fantasy and Wizardry titles, is available on Windows and macOS and has received a Very Positive review status on Steam. After a December 6 update, users reported virus warnings from antivirus programs like Norton, Avast, and McAfee, which were triggered by the game's use of the Pyxel engine and Pyinstaller for executable files. The developer advised users to exclude the game's .exe file from scans, but on December 12, Steam blocked the game from sale due to multiple virus reports. The developer requested a rollback to an earlier version, which prevented future updates. They purchased Norton Antivirus for testing and attempted various solutions, including filing reports with antivirus companies and considering a code signing certificate. They identified that the use of Python’s “os.remove()” function contributed to the false alerts and implemented a workaround. However, antivirus software retained memory of flagged files, causing continued blocks. Ultimately, flipping the fairy image associated with the game’s file by 180 degrees allowed Dungeon Antiqua to bypass the antivirus barriers and resume updates.

LNK Files And SSH Commands: A New Cyber Attack Trend In 2024

Cyber attackers are increasingly using malicious LNK files, which disguise themselves as harmless shortcuts, as an infection vector in 2024. Security experts, particularly Cyble Research and Intelligence Labs (CRIL), have noted a significant rise in this tactic. Attackers leverage LNK files to gain access to systems, triggering malicious actions that can deploy advanced malware. This method reflects a shift in attack vectors aimed at bypassing traditional security measures. One primary technique in these attacks is the exploitation of Living-off-the-Land Binaries (LOLBins), which are trusted system binaries manipulated to execute harmful commands without external malware. Attackers have refined their methods to evade detection by endpoint detection and response (EDR) solutions. Recent campaigns have incorporated SSH commands within malicious LNK files, allowing attackers to establish persistent connections and download malicious files from remote servers. This use of SSH is concerning as it is not typically associated with Windows systems, making it harder for conventional security measures to detect. Threat actors have also used SSH commands to execute malicious PowerShell or CMD commands indirectly through LNK files. For example, a malicious LNK file was found to trigger a PowerShell script that downloaded a malicious payload. Advanced Persistent Threat (APT) groups, known for their long-term cyber espionage, are increasingly utilizing these techniques, with groups like Transparent Tribe deploying stealer malware using similar methods. The combination of LNK files and SSH commands presents a significant threat to organizations, necessitating enhanced monitoring and detection systems to identify abnormal activities. Security teams must evolve EDR solutions to recognize malicious SSH and SCP activity, especially in environments where SSH is not commonly used. Additionally, organizations should restrict the use of legitimate SSH utilities and disable unnecessary features to minimize the attack surface.

Can Antivirus Software Protect Against Zero-Day Exploits?

The text discusses the increasing threat of cyberattacks due to reliance on digital devices without adequate protection, particularly antivirus software. It highlights the dangers of phishing and ransomware attacks, especially for businesses. Zero-day threats are described as vulnerabilities in software unknown to developers, which hackers exploit before a fix is available. Traditional antivirus systems primarily use signature-based detection and heuristic analysis, which are ineffective against zero-day exploits. To combat these threats, advanced strategies like Endpoint Detection and Response (EDR), artificial intelligence (AI), and Next-Generation Antivirus (NGAV) are being developed. A multi-layered security strategy is recommended, combining various tools and practices to enhance protection against cyber threats.

The Risks Of Using Outdated Antivirus Software

Antivirus software is essential for protecting devices from cyber threats, but simply installing it is not enough; outdated software can lead to vulnerabilities. Outdated antivirus systems are less effective against new malware and phishing techniques, limiting their functionality and increasing the risk of data breaches. Cybercriminals often target outdated systems, which are easier to exploit due to their diminished ability to recognize threats. Additionally, technical support for older antivirus versions may become unavailable, leaving systems defenseless. To maximize security, it is crucial to keep antivirus software updated and consider additional security measures like firewalls and two-factor authentication.

Do Macs Need Antivirus Protection?

Mac computers by Apple are known for their design, performance, and security features, but they are not immune to viruses and malware. macOS includes built-in security measures like Gatekeeper, XProtect, and Sandboxing, which help protect against cyber threats, but these features are not foolproof. High-profile malware campaigns, such as Silver Sparrow and Shlayer, have targeted macOS, highlighting the need for user vigilance. Antivirus software can provide additional security by offering real-time monitoring, continuous scanning, and privacy tools. Users who engage only with trusted sites and download apps from the Mac App Store may find built-in protections sufficient, but risks remain, including zero-day vulnerabilities and phishing attempts. Enhancing security can involve enabling the firewall, keeping macOS updated, using strong passwords, and activating FileVault for data encryption. While antivirus may not be essential for all Mac users, it can offer peace of mind, depending on individual online habits and data sensitivity.
