The 12 Best Antivirus Software for Mac, Compared and Priced

GBHackers ranks 12 Mac antivirus products, naming Bitdefender best overall and noting Gen Digital owns Norton, Avast, and Avira.

GBHackers scored twelve Mac antivirus products, ranking Bitdefender first at 8.8/10, followed by Intego, Malwarebytes, and ESET. The piece highlights that Gen Digital owns Norton, Avast, and Avira following the NortonLifeLock-Avast merger, so three of the twelve options share one corporate owner. It advises comparing year-two renewal prices rather than discounted first-year pricing and notes macOS already ships XProtect, Gatekeeper, and automatic malware removal. The 2026 Mac threat model described is infostealers harvesting passwords, cookies, and wallets via cracked software, fake installers, and malicious search ads.

Chaotic Eclipse Releases GenDigital Avast Antivirus ZeroDay PrettyPrague

Researcher Chaotic Eclipse released PrettyPrague, a PoC zero-day privilege escalation exploit against fully patched GenDigital Avast Antivirus.

Security researcher Chaotic Eclipse (also known as INFINITE NIGHTMARE or MSNightmare) published a PoC named PrettyPrague exploiting a zero-day privilege escalation flaw in Avast Antivirus. The PoC abuses a flaw in the Avast Sandbox to dump the Windows SAM database and spawn a SYSTEM-level shell, reportedly working on fully patched Avast and patched Windows 11 25H2. The researcher believes the flaw may also affect other GenDigital products such as AVG and Norton. It follows his recent HardBreacher PoC for a Kaspersky Endpoint Security privilege escalation flaw.

AI helps scammers build convincing antivirus renewal pages

Malwarebytes found scammers using AI to build polished fake antivirus renewal pages impersonating Avast, harvesting names, emails and phone numbers for follow-up fraud calls.

Malwarebytes analyzed a fake Avast renewal site targeting Belgian users in French, claiming a €129.99 Avast Premium Security renewal and collecting name, email address and Belgian mobile number through a cancellation form. Leftover code comments written in polite French and other stylistic clues suggest the page was generated with AI assistance, and the form was never connected to send data anywhere. The scam typically progresses to phone calls pressuring victims to install remote access software, and AI substantially lowers the barrier for producing polished, localized scam pages at scale.

ESET researchers observed the Russia-aligned group UAC-0099 inserting a decoy prompt injection into a VBScript used to install its MATCHBOIL loader in an attack against a Ukrainian target, aiming to make LLM-based code scanners refuse and stop inspecting the file.

Serial Microsoft 0-day hunter drops yet another Defender exploit

Researcher Nightmare Eclipse released ShieldCrash, a Microsoft Defender zero-day PoC that bypasses September patches and reads files as SYSTEM.

Zero-day researcher Nightmare Eclipse (MSNightmare) published ShieldCrash, their 11th Microsoft zero-day, a proof-of-concept bypass of the ShieldBreak patch (CVE-2026-69414), which itself had bypassed the fix for RoguePlanet (CVE-2026-50656). ShieldCrash works on Windows 10, Windows 11, and Windows Server systems that have applied the September 2026 patches and allows arbitrary file reads as SYSTEM, though not arbitrary writes or a full SYSTEM shell. Microsoft has not said when it plans to patch the issue. The researcher recently also released zero-days affecting CrowdStrike Falcon (FalconFlank), Kaspersky endpoint antivirus (HardBreacher, patched), and Gen Digital's Avast (PrettyPrague).

Iranian Hackers Pose as Recruiters to Deliver Cross

Kaspersky attributes new cross-platform RATs NodeRabbit and PollCat to Iranian group Nimbus Manticore, spread via recruiter-themed LinkedIn lures.

Kaspersky links two previously undocumented malware families, NodeRabbit (Node.js) and PollCat (obfuscated JavaScript), to the Iranian threat actor Nimbus Manticore, also known as Iranian Dream Job. Victims in Afghanistan, Egypt, and Ethiopia received trojanized coding challenge archives containing fake npm packages (colorized_terminal, pretty-log) that silently launched the RATs as background processes. NodeRabbit contacts Azure-hosted C2 servers via checkin, task, and result API endpoints and supports 11 commands including shell execution, file operations, and network enumeration. Persistence is platform-specific: Windows Run keys or scheduled tasks, Linux cron entries, and macOS launch agents, impersonating Microsoft Edge updates or Intel's Driver & Support Assistant.
