Account takeover seriously threatens both customers and businesses. It causes damage to brands, erodes customer trust, and can impact business profitability.
To effectively address account takeover, you must involve everyone in the business. This includes marketing, IT, HR, and higher-level management.
Detecting Credential Stuffing
Whether you’re a consumer or a business, credential-stuffing attacks are among the most dangerous online threats. These attacks are designed to take over user accounts for various reasons, from financial fraud to identity theft. Fortunately, there is some advanced account takeover protection solution to detect and prevent credential-stuffing attacks from happening.
The first step is to ensure your users change their passwords frequently and don’t reuse them across multiple services. This will dramatically reduce the likelihood of attackers gaining access to your credentials through a breached password.
Another important measure is to require multi-factor authentication for every account. This security mechanism can include traditional username and password combinations, a security token via text message or a mobile app, or a biometric verification method such as fingerprint scanning.
Additionally, it’s also important to use a specialized security platform to monitor for any unusual login attempts from an IP address that is not known to your organization. This way, you can quickly identify a fraudulent IP and take action to mitigate risk.
The consequences are often severe when a business suffers from a credential-stuffing attack. It can lead to lost revenue, brand damage, and customer churn. In addition, the clean-up and remediation costs can severely strain a business’s budget.
In the wake of a data breach, hackers can easily find leaked passwords used to launch credential-stuffing attacks. These stolen credentials are often sold to cyber criminals on the dark web.
Hackers use these credentials to access high-value sites, which they can exploit for monetary gains or other criminal activities. For example, they can steal gift cards or loyalty point balances from eCommerce websites or transfer money from a bank to their accounts.
The best defense against a credential stuffing attack is implementing a robust bot management solution that combines a strong password policy, employee education, and AI-powered bot detection tools. These tools will help you identify and block malicious bots before they can compromise your site or apps.
Detecting Bot Attacks
Bots are the backbone of many nefarious activities, including fraud, malware infections, DDoS attacks, and other cyber threats. They are a threat actor’s weapon of choice, and the proliferation of these automated programs makes them increasingly difficult to detect and mitigate.
Luckily, modern solutions employ a behavior-based approach to identify and prevent bots that pose serious security threats. These solutions use machine learning to analyze hundreds of variables and spot small anomalies in user behaviors and network signatures.
For example, increasing logins from unknown IP addresses or locations can signal malicious bot traffic. Other indicators include:
- A high bounce rate.
- Unusual IPs and geo-locations.
- Suspicious hits from single IPs.
A good bot detection solution will be able to provide detailed information on the origin and destination of each request. This allows you to distinguish human traffic from bot traffic and identify suspicious activity before it reaches your users.
A bot detection solution must recognize and track bot traffic and business logic attacks from all web, mobile, and API channels to be effective. This is necessary to protect against account takeover attacks, competitive price scraping, and other bot-based threats.
It also needs to be able to automatically enforce policies against bot and business logic traffic in real time. This is essential to ensure that only legitimate users can access your site.
Other detection techniques include device fingerprinting and device hashes, which can help to identify returning users and bots, even if they attempt to pass off as different people. Additionally, real-time monitoring and device tracking can identify suspicious logins and show their origin, even if they occur 200 miles from the user’s location.
Detecting Malicious Logins
A critical part of security is detecting malicious logins and preventing them. This requires an advanced solution that detects and blocks malicious attempts, identifies legitimate user attempts, and alerts you to them.
Malicious logins can result from different attacks. Some of these include credential-stuffing botnets that attempt to use stolen login information from other sites and services to log into your organization.
Another way that hackers can steal credentials is through phishing attacks. These emails come from a trusted source, such as a bank or an online service provider, and include links to fake login screens.
These phishing scams often take advantage of person-to-person trust and can lead to the loss of valuable information or financial data that could be used for identity theft or fraud. These phishing scams are usually done through email but can also include fraudulent phone calls and text messages.
Using a combination of AI, machine learning, and behavioral analytics, Barracuda can automatically identify and block account takeover attempts and attacks launched from compromised accounts. This is done by analyzing historical and inbound data to identify behavioral, content, and link-forwarding anomalies that can compromise user credentials and data.
