Process Doppelganging | Breaking Cybersecurity News | The Hacker News

The fileless code injection technique called Process Doppelgänging is actively being used by not just one or two but a large number of malware families in the wild, a new report shared with The Hacker News revealed. Discovered in late 2017, Process Doppelgänging is a fileless variation of Process Injection technique that takes advantage of a built-in Windows function to evade detection and works on all modern versions of Microsoft Windows operating system. Process Doppelgänging attack works by utilizing a Windows feature called Transactional NTFS (TxF) to launch a malicious process by replacing the memory of a legitimate process, tricking process monitoring tools and antivirus into believing that the legitimate process is running. Few months after the disclosure of this technique, a variant of the SynAck ransomware became the first-ever malware exploiting the Process Doppelgänging technique, targeting users in the United States, Kuwait, Germany, and Iran. Shortly after th...

Security researchers have spotted the first-ever ransomware exploiting Process Doppelgänging , a new fileless code injection technique that could help malware evade detection. The Process Doppelgänging attack takes advantage of a built-in Windows function, i.e., NTFS Transactions, and an outdated implementation of Windows process loader, and works on all modern versions of Microsoft Windows OS, including Windows 10. Process Doppelgänging attack works by using NTFS transactions to launch a malicious process by replacing the memory of a legitimate process, tricking process monitoring tools and antivirus into believing that the legitimate process is running. If you want to know more about how Process Doppelgänging attack works in detail, you should read this article  I published late last year. Shortly after the Process Doppelgänging attack details went public, several threat actors were found abusing it in an attempt to bypass modern security solutions. Security researc...

Everybody knows browser extensions are embedded into nearly every user's daily workflow, from spell checkers to GenAI tools. What most IT and security people don't know is that browser extensions' excessive permissions are a growing risk to organizations. LayerX today announced the release of the Enterprise Browser Extension Security Report 2025 , This report is the first and only report to merge public extension marketplace statistics with real-world enterprise usage telemetry. By doing so, it sheds light on one of the most underestimated threat surfaces in modern cybersecurity: browser extensions. The report reveals several findings that IT and security leaders will find interesting, as they build their plans for H2 2025. This includes information and analysis on how many extensions have risky permissions, which kinds of permissions are given, if extension developers are to be trusted, and more. Below, we bring key statistics from the report. Highlights from the Enterprise Browse...

A team of security researchers has discovered a new malware evasion technique that could help malware authors defeat most of the modern antivirus solutions and forensic tools. Dubbed Process Doppelgänging , the new fileless code injection technique takes advantage of a built-in Windows function and an undocumented implementation of Windows process loader. Ensilo security researchers Tal Liberman and Eugene Kogan, who discovered the Process Doppelgänging attack, presented their findings today at Black Hat 2017 Security conference held in London. Process Doppelgänging Works on All Windows Versions Apparently, Process Doppelgänging attack works on all modern versions of Microsoft Windows operating system, starting from Windows Vista to the latest version of Windows 10. Tal Liberman, the head of the research team at enSilo, told The Hacker New that this malware evasion technique is similar to Process Hollowing—a method first introduced years ago by attackers to defeat the m...
