Maintaining cyber resilience across your ecosystem is a significant challenge that must not be brushed aside as the likelihood of experiencing a cyber incident increases year after year. For example, in 2021 alone, there were multiple attacks on Critical National Infrastructure (CNI) such as Colonial Pipeline and against the Oldsmar, Fla. water treatment plant.

The cybersecurity threat landscape is continuously evolving, with the frequency and impacts of threats like malware and ransomware increasing every year. Today, organizations of all sizes and in every industry sector must be proactively searching for emerging threats and actively monitoring risk to protect themselves – and respond quickly in the event that a threat is identified.

Trustwave security and engineering teams are actively investigating the vulnerabilities CVE-2022-22965 (also referenced by other vendors at Spring4Shell / SpringShell) and CVE-2022-22963 and potential exploits. We are diligently watching over our clients for exposure and associated attacks and are taking action with approved mitigation efforts.

The dangers of email security are often understated. One successful email attack can lead to malware injection, system compromise, impersonation, espionage, ransomware and more. After all, phishing remains the top attack vector used by hackers. The FBI reported phishing scams were extremely prominent, with 323,972 complaints being made in the U.S. in 2021, compared to 241,342 the previous year. Adjusted losses resulting from these attacks is more than $44 million, a $10 million decrease from 2020.
