Leveraging device intelligence to outsmart evolving bot threats

Leveraging device intelligence to outsmart evolving bot threats

Bots dominate internet traffic. In 2023, bad bots accounted for 32% of web activity, the highest level ever recorded. Combined with good bots, nearly half of all traffic isn’t human. These automated threats can bypass traditional security measures, compromising data integrity and straining network resources.

Bots hack user accounts, steal sensitive data, manipulate databases and launch DDoS (distributed denial-of-service) attacks that overwhelm servers. They clog bandwidth, slow websites, disrupt services and skew analytics. This degrades user experience and drives up operational costs for businesses across industries. Data breaches caused by bots also damage brand reputation and customer trust. 

With two-thirds of United States websites vulnerable to even basic bot attacks, enterprise defense strategies must evolve. Security leaders must adopt innovative detection techniques and leverage technologies like device intelligence to safeguard their digital assets and maintain data integrity.

Recognizing bot attacks

Not all bots are harmful, but even benign ones can impact site performance and analytics. Identifying bot activity is crucial for managing threats and maintaining accurate data. Traditional bot detection relies on simple indicators, including:

  • Short sessions: Extremely brief visit durations across multiple users.
  • Traffic spikes: Sudden, unexplained surges in website visits.
  • Impossible analytics: Unrealistic data, like billions of page views from a small user base.
  • High bounce rates: Visitors leaving immediately after accessing a single page.
  • Strange conversion patterns: Unusual or inconsistent rates of desired user actions.

However, these indicators often appear too late to prevent damage. Advanced bots may not even trigger these alarms.

Modern bots use sophisticated techniques to blend in with legitimate traffic. They mimic human behavior patterns, distribute attacks across many IP addresses and exploit normal-looking API calls. Traditional security tools, focused on known attack signatures, struggle to detect these advanced threats.

As a result, conventional bot prevention methods have become less effective. For example, CAPTCHAs used to be a reliable resource to deter bots, but now they actually may obstruct more legitimate users than automated scripts because many bots can solve these puzzles better than humans. 

IP blocking, another traditional bot defense method, has similar limitations. While this method can stop basic attacks, bots can use rotating addresses and proxies to mask their origin, making it difficult to distinguish them from legitimate users without risking false positives. 

Multi-factor authentication (MFA) is a powerful deterrent against bots attempting unauthorized logins, requiring additional verification steps that most bots can’t easily bypass. Microsoft has even said it’s 99% effective against being hacked. However, it’s impractical to implement MFA for every page or action on a website, so security teams must employ other strategies.

These limitations highlight the need for more advanced bot detection techniques.

Spotting bot activity through technical signals

Device and browser attributes can provide strong indications of bot activity. These technical clues help separate human visitors from automated threats:

IP addresses

Certain IP addresses and proxies are commonly associated with bot activity. Effective bot detection systems use regularly updated databases of known bot-related IPs, data centers and malicious proxies. While bots frequently change IPs, a dynamic blocklist still provides a valuable verification layer. 

Device characteristics

Examining device and browser characteristics can reveal suspicious visitors. For example, a bot might claim to be using an iPhone, but its screen resolution doesn’t match any known iPhone model. Or it might report a Windows operating system while using a Mac-only font. These inconsistencies are red flags. 

Behavioral analysis

Behavioral analysis examines how visitors engage with websites and applications in real time. This technique monitors factors like mouse movements, keystroke patterns and navigation speed. By comparing these behaviors to typical human patterns, security systems can more accurately distinguish between legitimate users and bots. Machine learning (ML) algorithms enhance this process by continuously adapting to bot tactics and improving detection accuracy.

Honeypot traps

Honeypots are decoy pages or elements designed to attract bots while remaining invisible to genuine users. Interaction with a honeypot is a clear indicator of bot activity. This method is particularly effective against bots that indiscriminately crawl websites.

The power of device intelligence

Device intelligence is key to advanced bot detection. It goes beyond basic IP checks to analyze each device profile and assign a unique identifier. The platforms spot inconsistencies that signal bot activity to catch sophisticated bots that might fool simpler checks. 

By combining fingerprinting with behavioral analysis, device intelligence enables more accurate bot detection and a tiered risk system. It can trigger additional security measures like MFA for suspicious activities, balancing security with user experience.

AI-powered tools help businesses keep up with bot advancements. Machine learning analyzes billions of data points to continuously learn and adapt to changing behaviors. As bots get smarter, so do prevention techniques.  

Remember, overly aggressive security measures can drive away legitimate users. The goal is to block bots without creating friction for real people. Bot tactics evolve rapidly, so regular updates to your security strategy and threat intelligence are crucial to stay ahead. By layering multiple strategies, organizations can create a more robust defense against bot attacks and build a dynamic, adaptive security posture that protects both their assets and their users’ experiences.
