Today, every unpatched system, leaked password, and overlooked plugin is a doorway for attackers. Supply chains stretch deep into the code we trust, and malware hides not just in shady apps — but in job offers, hardware, and cloud services we rely on every day. Hackers don't need sophisticated exploits anymore. Sometimes, your credentials and a little social engineering are enough. This week, we trace how simple oversights turn into major breaches — and the silent threats most companies still underestimate. Let's dive in. ⚡ Threat of the Week UNC5221 Exploits New Ivanti Flaw to Drop Malware — The China-nexus cyber espionage group tracked as UNC5221 exploited a now-patched flaw in Ivanti Connect Secure, CVE-2025-22457 (CVSS score: 9.0), to deliver an in-memory dropper called TRAILBLAZE, a passive backdoor codenamed BRUSHFIRE, and the SPAWN malware suite. The vulnerability was originally patched by Ivanti on February 11, 2025, indicating that the threat actors studied the patch a...

What if attackers aren't breaking in—they're already inside, watching, and adapting? This week showed a sharp rise in stealth tactics built for long-term access and silent control. AI is being used to shape opinions. Malware is hiding inside software we trust. And old threats are returning under new names. The real danger isn't just the breach—it's not knowing who's still lurking in your systems. If your defenses can't adapt quickly, you're already at risk. Here are the key cyber events you need to pay attention to this week. ⚡ Threat of the Week Lemon Sandstorm Targets Middle East Critical Infra — The Iranian state-sponsored threat group tracked as Lemon Sandstorm targeted an unnamed critical national infrastructure (CNI) in the Middle East and maintained long-term access that lasted for nearly two years using custom backdoors like HanifNet, HXLibrary, and NeoExpressRAT. The activity, which lasted from at least May 2023 to February 2025, entailed "extensive es...

A set of five security vulnerabilities have been disclosed in the Terrestrial Trunked Radio ( TETRA ) standard for radio communication used widely by government entities and critical infrastructure sectors, including what's believed to be an intentional backdoor that could have potentially exposed sensitive information. The issues, discovered by Midnight Blue in 2021 and held back until now, have been collectively called  TETRA:BURST . There is no conclusive evidence to determine that the vulnerabilities have been exploited in the wild to date. "Depending on infrastructure and device configurations, these vulnerabilities allow for real time decryption, harvest-now-decrypt-later attacks, message injection, user deanonymization, or session key pinning," the Netherlands-based cybersecurity company  said . Standardized by the European Telecommunications Standards Institute (ETSI) in 1995, TETRA is used in more than 100 countries and as a police radio communication system ...

A new research has yielded yet another means to pilfer sensitive data by exploiting what's the first "on-chip, cross-core" side-channel attack targeting the ring interconnect used in Intel Coffee Lake and Skylake processors. Published by a group of academics from the University of Illinois at Urbana-Champaign, the  findings  are expected to be presented at the USENIX Security Symposium coming this August. While information leakage attacks targeting the CPU microarchitecture have been previously demonstrated to break the isolation between user applications and the operating system, allowing a malicious program to access memory used by other programs (e.g., Meltdown and Spectre), the new attack leverages a contention on the ring interconnect. SoC  Ring interconnect  is an on-die bus arranged in a ring topology which enables intra-process communication between different components (aka agents) such as the cores, the last level cache (LLC), the graphics unit, and the...

Everything feels secure—until one small thing slips through. Even strong systems can break if a simple check is missed or a trusted tool is misused. Most threats don't start with alarms—they sneak in through the little things we overlook. A tiny bug, a reused password, a quiet connection—that's all it takes. Staying safe isn't just about reacting fast. It's about catching these early signs before they blow up into real problems. That's why this week's updates matter. From stealthy tactics to unexpected entry points, the stories ahead reveal how quickly risk can spread—and what smart teams are doing to stay ahead. Dive in. ⚡ Threat of the Week U.S. Disrupts N. Korea IT Worker Scheme — Prosecutors said they uncovered the North Korean IT staff working at over 100 U.S. companies using fictitious or stolen identities and not only drawing salaries, but also stealing secret data and plundering virtual currency more than $900,000 in one incident targeting an unnamed blockchain company in ...

Cybercrime has stopped being a problem of just the internet — it's becoming a problem of the real world. Online scams now fund organized crime, hackers rent violence like a service, and even trusted apps or social platforms are turning into attack vectors. The result is a global system where every digital weakness can be turned into physical harm, economic loss, or political leverage. Understanding these links is no longer optional — it's survival. For a full look at the most important security news stories of the week, keep reading.

Some of the biggest security problems start quietly. No alerts. No warnings. Just small actions that seem normal but aren't. Attackers now know how to stay hidden by blending in, and that makes it hard to tell when something's wrong. This week's stories aren't just about what was attacked—but how easily it happened. If we're only looking for the obvious signs, what are we missing right in front of us? Here's a look at the tactics and mistakes that show how much can go unnoticed. ⚡ Threat of the Week Apple Zero-Click Flaw in Messages Exploited to Deliver Paragon Spyware — Apple disclosed that a security flaw in its Messages app was actively exploited in the wild to target civil society members in sophisticated cyber attacks.

Cybersecurity researchers have tied a fresh round of cyber attacks targeting financial services to the notorious cybercrime group known as Scattered Spider , casting doubt on their claims of going "dark." Threat intelligence firm ReliaQuest said it has observed indications that the threat actor has shifted their focus to the financial sector. This is supported by an increase in lookalike domains potentially linked to the group that are geared towards the industry vertical, as well as a recently identified targeted intrusion against an unnamed U.S. banking organization. "Scattered Spider gained initial access by socially engineering an executive's account and resetting their password via Azure Active Directory Self-Service Password Management," the company said . "From there, they accessed sensitive IT and security documents, moved laterally through the Citrix environment and VPN, and compromised VMware ESXi infrastructure to dump credentials and furthe...

A group of academics from Ruhr University Bochum and New York University Abu Dhabi have uncovered security flaws in 4G LTE and 5G networks that could potentially allow hackers to impersonate users on the network and even sign up for paid subscriptions on their behalf. The impersonation attack — named " IMPersonation Attacks in 4G NeTworks " (or IMP4GT ) — exploits the mutual authentication method used by the mobile phone and the network's base station to verify their respective identities to manipulate data packets in transit. "The IMP4GT attacks exploit the missing integrity protection for user data, and a reflection mechanism of the IP stack mobile operating system. We can make use of the reflection mechanism to build an encryption and decryption oracle. Along with the lack of integrity protection, this allows to inject arbitrary packets and to decrypt packets," the researchers explained. The research was presented at the Network Distributed System Se...

Even in well-secured environments, attackers are getting in—not with flashy exploits, but by quietly taking advantage of weak settings, outdated encryption, and trusted tools left unprotected. These attacks don't depend on zero-days. They work by staying unnoticed—slipping through the cracks in what we monitor and what we assume is safe. What once looked suspicious now blends in, thanks to modular techniques and automation that copy normal behavior. The real concern? Control isn't just being challenged—it's being quietly taken. This week's updates highlight how default settings, blurred trust boundaries, and exposed infrastructure are turning everyday systems into entry points. ⚡ Threat of the Week Critical SharePoint Zero-Day Actively Exploited (Patch Released Today) — Microsoft has released fixes to address two security flaws in SharePoint Server that have come under active exploitation in the wild to breach dozens of organizations across the world.

A cloud threat actor group tracked as 8220 has updated its malware toolset to breach Linux servers with the goal of installing crypto miners as part of a long-running campaign. "The updates include the deployment of new versions of a crypto miner and an IRC bot," Microsoft Security Intelligence said in a series of tweets on Thursday. "The group has actively updated its techniques and payloads over the last year." 8220, active since early 2017 , is a Chinese-speaking, Monero-mining threat actor so named for its preference to communicate with command-and-control (C2) servers over port 8220. It's also the developer of a tool called whatMiner, which has been co-opted by the Rocke cybercrime group in their attacks. In July 2019, the Alibaba Cloud Security Team uncovered an extra shift in the adversary's tactics, noting its use of rootkits to hide the mining program. Two years later, the gang resurfaced with Tsunami IRC botnet variants and a custom ...

The U.S. Department of State has  announced  monetary rewards of up to $10 million for information about individuals holding key positions within the Hive ransomware operation. It is also giving away an additional $5 million for specifics that could lead to the arrest and/or conviction of any person "conspiring to participate in or attempting to participate in Hive ransomware activity." The multi-million-dollar rewards come a little over a year after a coordinated law enforcement effort  covertly infiltrated and dismantled  the darknet infrastructure associated with the Hive ransomware-as-a-service (RaaS) gang. One person with suspected ties to the group was  arrested  in Paris in December 2023. Hive, which emerged in mid-2021, targeted more than 1,500 victims in over 80 countries, netting about $100 million in illegal revenues. In November 2023, Bitdefender  revealed  that a new ransomware group called Hunters International had acquired the s...
