Cyberduck log4j vulnerability1/30/2024 ![]() The attackers in the SolarWinds Orion breach, meanwhile, are believed to have had access for nine months to “some of the most sophisticated networks in the world,” including cybersecurity firm FireEye, Microsoft, and the U.S. (“They were incredibly careful, and patient,” a person briefed on the investigation told the Times, speaking of the attackers.) Wired reported that the attackers may have been stealing data over the course of a full year. In the case of the Sony breach of 2014, the New York Times reported that the attackers spent two months mapping the company’s systems and identifying key files. Over the past week, “we’ve already seen the use of obfuscation to avoid detection,” Karas said. It’s not that hackers can’t be detected in this situation, but they also continuously hone their tactics to evade detection attempts, said Asaf Karas, chief technology officer for security at JFrog. ![]() Other activities can include exfiltrating data slowly - so slowly that it typically won’t be blocked or detected, Gurzeev said. This helps them strategize how to most effectively avoid existing security practices and tools, Schless said, “while simultaneously identifying what parts of the infrastructure would be most effective to encrypt for a ransomware attack.” Once they’ve established a foothold, sophisticated attackers will often take their time in surveying users and security protocols before executing the full brunt of their attacks, said Hank Schless, senior manager for security solutions at Lookout. “Their business model is built on scale and reliability of intrusion,” he said.Īnd crucially, “sophisticated attackers don’t want to get caught before they’ve gotten their job done, so they tend to develop techniques and operating practices that make them quieter, and harder to see,” Ellis said. In comparison to the hobbyists, these attackers are more like a multinational enterprise, Ellis said. Those include attackers looking to get a foothold in networks in order to sell that access to ransomware operators. But evidence has emerged that more sophisticated threat actors have begun to exploit the vulnerability in Log4j, as well. Most of the malicious attack volume over the past week has involved “hobbyists” or solo operators, said Casey Ellis, founder and chief technology officer at Bugcrowd. Researchers at the company said they’ve observed attempted exploits on more than 44% of corporate networks worldwide. The vulnerability in the widely used Log4j logging library was publicly revealed a week ago, and an onslaught of more than 1 million attempted attacks have followed, according to Check Point.
