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.

Global optics manufacturer Hoya had business operations at its headquarters and several business divisions impacted and is now facing a “No Negotiation / No Discount Policy” $10 million ransom decision to make.

A new survey of physicians details the devastating impact of the Change Healthcare cyber attack on the healthcare sector. In February, a cyber attack on Change Healthcare brought much of the U.S. healthcare system to a halt. The revenue and payment cycle management provider is central to connecting payers, providers and patients within the U.S. healthcare system to ensure payments are made.

April 16, 2024: UnitedHealth Group, parent of Change Healthcare, reported on April 16, 2024 in its Q1 results a negative impact of $872 million “in unfavorable cyberattack effects” due to cyberattack direct response costs and the business disruption impacts. The company anticipates additional costs associated with the attack.

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?

Brute force attacks are one of the most common methods used by cybercriminals to steal credentials from organizations. To prevent brute force attacks, organizations need to enforce the use of strong and unique passwords, invest in a business password manager, require employees to enable MFA, monitor and limit login attempts, implement passwordless authentication and delete inactive accounts.

If over 40 major banks can be the target of JavaScript injection attacks, let’s be honest – so can you. In 2023, a malware campaign using this attack method affected 50,000 user sessions across more than 40 financial institutions worldwide, leaving many dev teams in pure damage-control mode. A large number of professional developers (especially front-end developers) use JavaScript more often than any other programming language.
