Small and medium businesses are increasingly exposed to email-based attacks that rely on compromised accounts and trusted communication patterns. In a typical business email compromise scenario, attackers gain access to an executive’s email account and monitor communication over time. This allows them to understand how financial requests are handled and when key individuals are unavailable. At the right moment, they send emails that appear legitimate.

Brand impersonation account takeover (ATO) happens when attackers use fake brand assets to expose customers, harvest credentials, and attempt access on the legitimate site. The impersonation stage happens outside the enterprise’s login environment, but the ATO risk appears when stolen credentials, attacker devices, or exposed users reach the legitimate login environment. That distinction matters because brand impersonation and account takeover are often handled as separate problems.

Ransomware is a type of malware that blocks access to a victim’s system or network. Once the attack runs, it can encrypt selected files, lock systems, or disrupt access to business operations. Then, they demand a ransom in exchange for restoring access or providing a decryption key. In many cases, ransomware encrypts files so the victim cannot use them. Some ransomware can also lock systems or disrupt access to business operations.

From a fast-growing ransomware affiliate network to a politically motivated DDoS collective and a prolific data extortion group, these three threat actors represent distinct but pressing risks across sectors and regions. CYJAX breaks down what each group does, why they matter, and what security teams should know.

Google recently released Device-Bound Session Credentials (DBSC) for Google Chrome and Google Workspace. It is a long-awaited new security enhancement to fight back against local cookie theft. But, yes, it can still be hacked and phished. Nothing alone in cybersecurity is a complete panacea.

Researchers at Malwarebytes warn that a fake ChatGPT download site is delivering malware. The attackers use sponsored results and SEO manipulation to target users who search for “ChatGPT download.” The phishing page is a convincingly spoofed version of the legitimate ChatGPT website, which delivers malware tailored to Windows or Mac users.

Cyberattacks are now the top concern of leading CEOs, overtaking fears over geopolitical turmoil or inflation, the Wall Street Journal reports. A survey by the Conference Board and the Business Council found that 65% of CEOs at blue-chip companies cited cyberattacks as their top worry in the second quarter of 2026, an increase from 56% in Q1 2026.
