Threats, Attack Techniques, and Targets
In May 2026, new threats appeared on the dark web. ASEC Blog reports that a new data extortion group called ‘Leak Bazaar’ has emerged. This group focuses on stealing and threatening to release sensitive information. They are part of a growing trend of data theft and extortion.
There are reports of large-scale supply chain attacks. Attackers use malware like the Shaid-Hulud worm to infect multiple organizations at once. This virus can spread through complex supply networks. It targets various industries, especially those with links to technology suppliers.
