Attackers predominantly use phishing attacks to steal and misuse user identities. A global Statista study on employee-reported malicious emails revealed that in the first quarter of 2023, 58.2% of malicious emails were credential theft attacks, 40.5% were impersonation attacks, and 1.3% were malware deliveries. Phishing attacks create a sense of urgency and panic in users, who, as a result, easily fall victim to them.

Vulnerabilities are everywhere and often exploited. For example, in 2023, over 29,000 critical and high vulnerabilities were discovered across approximately 1,400 applications. The dynamic and evolving attack surfaces make it harder to protect against these threats. When the attack surface gets bigger, so does the risk of cyber attacks. This blog delves into what an attack surface is and recommends best practices in attack surface reduction.

Cybercriminals use a variety of cyber attacks to steal your sensitive information. However, a password manager can help prevent you from falling victim to them. Password managers protect your sensitive information from being stolen by unauthorized users by ensuring that your passwords are strong and unique. They also protect your sensitive information from getting stolen by using autofill features and encryption.

Recently a large service provider in Eastern Europe contacted the A10 threat research team for insight into a series of DDoS attacks against its network. While the attacks were not service impacting, the frequency and persistence of the attacks raised internal concerns that the attacks might mask a more malicious intent: could this be a state actor planting malware or testing their defenses for a larger attack against critical infrastructure?

Welcome to the 17th edition of Cloudflare’s DDoS threat report. This edition covers the DDoS threat landscape along with key findings as observed from the Cloudflare network during the first quarter of 2024.

With DDoS attacks on the rise—surpassing 4.25 billion in 2023—the right protection is crucial. Costly downtime—$6,130/minute—underscores the urgency. These attacks are getting more sophisticated, especially those that target the application layer. They’re hard to spot because they look like normal traffic and can seriously mess up a company’s operations and finances.
