Over a Dozen Chrome Extensions Caught Hijacking Google Search Results for Millions

New details have emerged about a vast network of rogue extensions for Chrome and Edge browsers that were found to hijack clicks to links in search results pages to arbitrary URLs, including phishing sites and ads. Collectively called "CacheFlow" by Avast, the 28 extensions in question — including...

Exfiltrating Data from Air-Gapped Computers via Wi-Fi Signals (Without Wi-Fi Hardware)

A security researcher has demonstrated that sensitive data could be exfiltrated from air-gapped computers via a novel technique that leverages Wi-Fi signals as a covert channel—surprisingly, without requiring the presence of Wi-Fi hardware on the targeted systems. Dubbed "AIR-FI," the attack hing...

Researchers have found vulnerabilities in several processors. The vulnerabilities marked CVE-2020-8694 and CVE-2020-8695 have been named Platypus, an acronym for Power Leakage Attacks: Targeting Your Protected User Secrets. The vulnerabilities allow a local malicious person to obtain obtain...

HTTP-revshell - Powershell Reverse Shell Using HTTP/S Protocol With AMSI Bypass And Proxy Aware

HTTP-revshell is a tool focused on redteam exercises and pentesters. This tool provides a reverse connection through the http/s protocol. It use a covert channel to gain control over the victim machine through web requests and thus evade solutions such as IDS, IPS and AV. Help server.py unisessio...

SNIcat - Server Name Indication Concatenator

SNIcat is a proof of concept tool that performs data exfiltration, utilizing a covert channel method via. Server Name Indication , a TLS Client Hello Extension. The tool consists of an agent which resides on the compromised internal host, and a Command &Control Server which controls the agent and...

Intel, ARM, IBM, AMD Processors Vulnerable to New Side-Channel Attacks

It turns out that the root cause behind several previously disclosed speculative execution attacks against modern processors, such as Meltdown and Foreshadow, was misattributed to 'prefetching effect,' resulting in hardware vendors releasing incomplete mitigations and countermeasures. Sharing its...

New Noise-Resilient Attack On Intel and AMD CPUs Makes Flush-based Attacks Effective

Modern Intel and AMD processors are susceptible to a new form of side-channel attack that makes flush-based cache attacks resilient to system noise, newly published research shared with The Hacker News has revealed. The findings are from a paper "DABANGG: Time for Fearless Flush based Cache...

Exfiltrating Data from Air-Gapped Computers Using Screen Brightness

It may sound creepy and unreal, but hackers can also exfiltrate sensitive data from your computer by simply changing the brightness of the screen, new cybersecurity research shared with The Hacker News revealed. In recent years, several cybersecurity researchers demonstrated innovative ways to...
