IoT Devices with Outdated Secure Firmware
Security professionals historically focused on protecting mobile devices and computers. Today, over a billion IoT devices communicate with enterprises, creating billions of potential attack vectors. Manufacturers prioritize building new devices over security updates. Devices remain secure at purchase but become vulnerable when hackers discover bugs, especially in open source software. Legacy systems connected to IoT devices also pose risks.
Use of Weak and Default Credentials
IoT companies sell devices with default credentials like "admin" and "password." Hackers use brute-force attacks. The Mirai botnet attack exemplifies this vulnerability.
Lack of Encryption
Encryption prevents hacker access, but devices lack storage and processing capabilities of traditional computers. Unused bandwidth or processing power can be exploited. Hackers manipulate protection algorithms.
Malware and Ransomware
Cybercriminals lock consumers out of their devices. IoT-enabled cameras capturing confidential information can be hacked with malware, then encrypted through ransomware. City-wide infrastructure devices infected with malware can launch DDoS or man-in-the-middle attacks, compromising entire municipal command and control infrastructure.
Predicting and Preventing Phishing Attacks
Phishing affects all enterprise technologies, and IoT represents a new attack vector. Hackers send signals triggering device complications. Cloud services use threat intelligence, AI-powered monitoring, and analytics tools, though adapting these to IoT is complex due to instant data processing requirements.
Wide Area Networks
WAN are city-wide networks controlling communication between essential services like smart meters and street lights. Malware uploaded to one trusted device compromises entire enterprise security.
Smart Homes Devices
More homes and offices integrate IoT connectivity. Exposed IP addresses reveal residential addresses and contact details, risking consumer safety.
