In 2019, most frequently seen attacks were UDP floods, SYN floods, and ACK floods, which together accounted for 82% of all DDoS attacks. By contrast, reflection attacks took up only 10%. Compared with 2018, reflection attacks rose slightly in number, but remained small in proportion.
Overview On June 23, NSFOCUS reported that Apache Dubbo contained a remote code execution vulnerability (CVE-2020-1948) resulting from deserialization. Apache Dubbo is a high-performance Java RPC framework. The vulnerability exists in Hessian, a default deserialization tool used by Apache Dubbo. An attacker may exploit it by sending malicious RPC requests which usually contain unidentifiable service […]
Key Findings: Maturity: The technical maturity of attackers keeps growing, opening more possibilities than DDoS attacks for attackers to garner profits. Combination: Of all DDoS attacks in 2019, 12.5% employed multiple vectors. This percentage was even higher among super-sized attacks (> 300 Gbps) to reach more than one-third. These factors have posed a greater challenge […]
Overview Recently, Apache Dubbo was reported to contain a remote code execution vulnerability (CVE-2020-1948) resulting from deserialization. Apache Dubbo is a high-performance Java RPC framework. The vulnerability exists in hessian, a default deserialization tool used by Apache Dubbo. An attacker may trigger it by sending malicious RPC requests which usually contain unidentifiable service or method […]
Deserialization vulnerabilities are still frequently exploited for web attacks and special attention should be paid to the security of mainstream frameworks. This section describes web vulnerabilities that had an extensive impact in 2019: WebLogic In 2017, Oracle released an official patch that fixed the XMLDecoder vulnerability (CVE-2017-10352) in WebLogic Server. This patch was evaded twice […]
Web Attack Trend Websites, which enterprises or individuals use to provide services for users, are usually the first choice of hackers during attacks. Web attacks in 2019 clung to traditional patterns and methods, including server information disclosure, resource leeching, cross-origin resource sharing (CORS), SQL injection, and cookie poisoning, which together accounted for 89% of web […]
