**Weekly Recap of Top Cyber Threats and Security Breaches**
*Staying Ahead of IoT Exploits, Crypto Wallet Attacks, and Rising Phishing Campaigns*
**Introduction**
In a digital landscape that grows more complex by the day, cyberattacks are no longer rare events—they’re persistent threats. Last week alone, multiple critical vulnerabilities were discovered in widely deployed IoT devices, a dangerous malware campaign targeted crypto wallets, and phishing techniques took yet another sophisticated turn, leaving organizations scrambling for answers.
According to IBM’s 2024 Cost of a Data Breach Report, 83% of organizations have experienced more than one breach in their lifetime. This should raise alarms, especially for CISOs, CEOs, and cybersecurity professionals tasked with defending systems that are under constant pressure from malicious actors.
You don’t need to wait for an incident to react—each of these weekly threats provides the opportunity to proactively test controls, update strategies, and assess organizational readiness. In this article, we’ll break down three of the most significant cybersecurity threats reported last week by *The Hacker News* (source: https://thehackernews.com/2026/01/weekly-recap-iot-exploits-wallet.html), explain why they matter, and—most importantly—show you what you can do about them.
Expect practical insights on:
– The vulnerabilities plaguing modern IoT devices and what they could mean for your infrastructure
– The tactics behind a novel crypto wallet hijacking campaign
– How phishing campaigns are bypassing 2FA and evading traditional filters
Let’s dig into what you need to know to keep your organization secure in this threat-laden climate.

**IoT Devices: The Hidden Entry Points You Can’t Ignore**
Internet of Things (IoT) devices are everywhere—from smart cameras and routers to HVAC systems and factory sensors. But their convenience often comes with a hidden cost: they’re one of the easiest ways for attackers to get inside your network.
Last week, researchers uncovered a series of critical remote code execution (RCE) flaws in popular IoT firmware used in home and industrial devices. These flaws, if exploited, allow attackers to take full control of the device without the need for authentication. Once an IoT device is compromised, it can serve as a gateway into your larger network—particularly if it’s not segmented properly.
What’s concerning is how often these devices:
– Operate with outdated firmware
– Lack centralized visibility
– Remain deployed with default credentials
Notably, in one documented case, attackers used the vulnerability to infiltrate a factory’s network and plant disruptive malware that halted operations for over 36 hours.
How you can respond:
– **Audit all IoT devices** across your environment and map them to your network topology
– **Implement strong segmentation**—isolate devices from critical systems and data
– **Automate patch management**, or work with vendors for firmware updates and lifecycle support
– **Monitor traffic for anomalies**, especially outbound connections from typically quiet devices
According to Gartner, by 2027, more than 75% of enterprise-managed endpoints will be IoT devices. That’s a massive attack surface—and one we can no longer afford to underestimate.

**Crypto Wallets Under Fire: Hijacking Through Browser Extensions**
Cryptocurrency continues to attract both investors and cybercriminals. In one of the more concerning campaigns last week, attackers launched a malicious browser extension pretending to be a routine browser privacy tool. In reality, once installed, the extension silently harvested wallet credentials and private keys, funneling them back to an attacker-controlled server.
The attack was clever in its simplicity:
– The extension asked for clipboard access permissions
– It monitored all copied text for wallet addresses or private keys
– If a crypto transaction was copied/pasted, it quietly replaced destination addresses with those controlled by the attackers
One victim reportedly lost over $120,000 in just a few minutes.
Key takeaways:
– **Train your teams**—especially finance and DevOps staff—on how these types of extensions work and how to vet them
– **Restrict extension installation** through centralized browser policies or browser isolation platforms
– Encourage the use of **hardware-based wallets** and encourage **two-factor authentication** (though attackers still find ways around it, as we’ll see next)
This is a reminder: even tech-savvy teams can get tricked when productivity and security collide.

**The Evolution of Phishing: Beyond 2FA and Into Your Inbox**
Phishing is no longer just about fake emails and poorly written Nigerian prince schemes. Criminals today mimic internal communications, clone legitimate login pages, and even intercept 2FA codes using real-time proxying techniques.
In a newly reported campaign, attackers used phishing links that routed users to accurately cloned login portals for Microsoft 365 and Google Workspace while simultaneously capturing their login credentials and session cookies. From there, victims were unknowingly logged in by the attacker via cookie hijacking—skipping 2FA altogether.
Recent stats from Proofpoint show that 71% of organizations experienced at least one phishing attack in 2025 that bypassed their email filters.
What you can do:
– **Deploy email security tools** that include behavior-based anomaly detection, not just SPF/DKIM checks
– **Enable risk-based authentication**, using contextual signals like location, device fingerprinting, or session behavior
– **Educate your users** with phishing simulation training—not just annual compliance videos, but ongoing exercises that stay current with threat trends
– Consider **tight session token policies**, such as shorter expiration times and stricter revocation upon logout
Phishing continues to evolve at pace with user behavior. As our defenses grow more sophisticated, so do the deception techniques.

**Conclusion**
The threats emerging each week are a stark reminder that attackers aren’t simply using brute-force efforts—they’re innovating with intent. Whether it’s exploiting overlooked IoT devices, slipping into a browser via an “innocent” extension, or tricking users with better phishing lures, cybercriminals are always searching for the path of least resistance.
But here’s the good news: by staying informed and responding with decisive, practical action, your organization can reduce exposure and stay a step ahead. From conducting IoT audits and tightening your browser policies to enabling smarter phishing defenses, every mitigation matters.
If you’re in a leadership position—CISO, CEO, or IT security decision-maker—make it a habit to review weekly threat reports like the one from *The Hacker News* (full article here: https://thehackernews.com/2026/01/weekly-recap-iot-exploits-wallet.html). Use them not only for awareness but as a catalyst for tactical action within your teams.
**Now is the time to turn threat visibility into threat readiness.** Share this recap with your teams, initiate one focused improvement this week, and be the reason your organization stays secure as the cyber landscape shifts.
