An unfamiliar name is showing up in ransomware notes and it’s backed by code, not bureaucracy. FOG ransomware is being distributed through phishing emails that reference the “Department of Government Efficiency,” deploying payloads that encrypt data. Victims receive ransom notes alongside scripts for data collection and privilege escalation. Since January, the campaign has claimed 100 victims across multiple sectors. A single enabled feature could open your network to remote control. ASUS has warned of a critical vulnerability in its routers when AiCloud is active. The flaw allows attackers to send specially crafted requests to run commands without authentication. Firmware updates are available, but until patched, users are advised to disable internet-facing services and secure admin interfaces. A forged email that passes every security check - that’s the new phishing trick. Attackers are using DKIM replay tactics to forward legitimate Google security alerts to unsuspecting victims.

Six million users and 57 extensions they probably shouldn’t trust. A wave of Chrome add-ons, many unlisted and quietly distributed through ads, have been caught with invasive capabilities. Laced with obfuscated code, several have been removed from the Chrome Web Store, but others still linger. A trio of exploited vulnerabilities just made CISA’s KEV list. Two affect Apple device, both patched in the latest iOS and macOS updates. The third, a Windows NTLM hash leak, has reportedly been used by groups like APT28. All three are now confirmed as actively exploited and fully patchable. Reward points and toll notices are the new bait. Researchers have flagged a surge in global SMS phishing attacks through two campaigns: PointyPhish and TollShark. Both rely on urgency, fake branding, and thousands of rapidly deployed domains via the Darcula Suite platform. From iMessage to RCS, no inbox is safe.

Mustang Panda has updated its arsenal and stealth is a priority. In a new campaign, it rolled out an upgraded version of its backdoor. Alongside it, new tools like StarProxy, Paklog, Corklog, and SplatCloakdriver were delivered through a dropper engineered to hunt down security products. Researchers have observed a fresh wave of Agent Tesla attacks using multi-stage loaders. The chain starts with a JavaScript file hidden in an archive, then pivots to PowerShell for in-memory execution. The malware finishes the job by injecting into trusted processes, effectively vanishing from traditional antivirus scans. A long-patched flaw is back in the spotlight and now it’s being exploited. SonicWall has updated its advisory for CVE-2021-20035, confirming active abuse in the wild. The bug affects SMA 100 series devices and allows authenticated users to execute arbitrary commands.

UNC5174 is keeping it quiet and clean. Since late 2024, the Chinese state-linked group has been targeting Linux environments using a domain-squatting infrastructure to deliver SNOWLIGHT malware and a new RAT. The campaign leans on stealth, — WebSockets for C2, bash scripts for delivery, and zero on-disk footprint — pointing to a mix of espionage and access brokering. It looks like a PDF tool, acts like malware. A new phishing campaign is spoofing a legitimate website to deliver a stealthy SectopRAT variant. Victims are funneled through cloned interfaces and fake CAPTCHAs before unknowingly executing PowerShell commands that drop the payload. Browser security just got a round of urgent fixes. Chrome 135 and Firefox 137 patch several critical bugs, including memory corruption issues that could lead to remote code execution. Thunderbird updates close off serious risks too.

Bots don’t sleep and AkiraBot proves it. Since late 2024, this spam operation has flooded over 400,000 websites, zeroing in on small businesses using platforms like Shopify, Wix, and Squarespace. The messages push shady SEO services, powered by AI-generated content to dodge filters. With rotating domains, CAPTCHA bypass tools, and an expanding reach into live chats and comment sections, AkiraBot is becoming harder to pin down. One bug, admin access - just like that. A critical flaw in the OttoKit WordPress plugin is being actively exploited, allowing attackers to create admin accounts and take over sites. Only some configurations are vulnerable, but where it hits, it hits hard. When a checkout page starts asking for your card details twice, something’s wrong. A WordPress site was found hosting a fake credit card form. The malicious script captured payment info and funneled it to a freshly registered domain, designed to look harmless, but built to steal.

A torrent download might be doing more than delivering cracked software. A campaign has been distributing ViperSoftX to Korean users, likely run by Arabic-speaking threat actors. The malware quickly expands its footprint by downloading multiple payloads. It even manipulates Windows Defender settings to stay hidden, making cleanup far more difficult once it’s embedded. Dell users have a new reason to check their patch status. Six vulnerabilities in PowerScale OneFS could expose systems to compromise, including one high-severity flaw that warrants immediate attention. While version 9.10.1.1 addresses the issues, Dell has provided workaround steps and targeted patches for older releases. What looks like a harmless file-sharing notification is actually the start of a RAT deployment. A new phishing campaign mimics messages from files[.]fm, warning users of file deletion to create urgency. Clicking through leads to a real landing page, ultimately triggering malware. The payload often includes ConnectWise RAT, giving attackers persistent, remote access to compromised systems.

Invasive spyware campaigns are zeroing in on high-risk communities. MOONSHINE and BADBAZAAR are being deployed through trojanized mobile apps to surveil Uyghur, Tibetan, and Taiwanese individuals, as well as civil society groups. Some of the apps mimic popular platforms, while others are tailored to target interests. The campaign reflects a broader strategy to monitor groups viewed as threats to state control. A zero-day in Windows' core logging system has made its way into active exploitation. A use-after-free bug in the CLFS driver is being targeted by the PipeMagic trojan to escalate privileges and gain system-level access. Once exploited, attackers can bypass security protections, deploy additional malware, and harvest sensitive data. Search for QuickBooks during tax season, and you might land on a trap. Threat actors are placing deceptive Google Ads that link to phishing pages almost identical to the real QuickBooks login portal. The tactic preys on urgency and familiarity, making it easy for distracted users to miss small red flags.
