The Web Proxy Auto-Discovery Protocol (WPAD), enabled by default on Windows and supported by other operating systems, can expose computer users’ online accounts, web searches, and other private data, security researchers warn.
Man-in-the-middle attackers can abuse the WPAD protocol to hijack people’s online accounts and steal their sensitive information even when they access websites over encrypted HTTPS or VPN connections, said Alex Chapman and Paul Stone, researchers with U.K.-based Context Information Security, during the DEF CON security conference this week.
WPAD is a protocol, developed in 1999 by people from Microsoft and other technology companies, that allows computers to automatically discover which web proxy they should use. The proxy is defined in a JavaScript file called a proxy auto-config (PAC) file.

Hundreds of millions of Android devices based on Qualcomm chipsets are likely exposed to at least one of four critical vulnerabilities that allow non-privileged apps to take them over.
The four flaws were presented by security researcher Adam Donenfeld from Check Point Software Technologies on Sunday at the DEF CON security conference in Las Vegas. They were reported to Qualcomm between February and April, and the chipset maker has since released fixes for the vulnerabilities after classifying them as high severity.
Unfortunately, that doesn’t mean that all devices are yet protected. Due to the fragmentation of the Android ecosystem, many devices run older Android versions and no longer receive firmware updates, or they receive the fixes with months-long delays.

Some consumer safes protected with electronic locks are quite easy to hack using basic techniques. Others, though, like those made to store guns, are designed to resist expert manipulation.
However, one hacker demonstrated at the DEF CON security conference Friday that even high-security rated electronic safe locks are susceptible to side-channel attacks typically used against cryptosystems.
Side-channel attacks involve techniques like analyzing power fluctuations and variations in the time it takes operations to complete on an electronic device. By monitoring these values when the system checks the user’s input against a stored value, attackers can incrementally recover encryption keys or, in the case of electronic safe locks, the correct access code.
