The Windows Subsystem for Linux (WSL) was introduced by Microsoft in the Windows 10 Anniversary Update. It allows users to run a full Linux user space in Windows. It is a much nicer approach for most applications than Cygwin, or using a Linux VM. It is not an emulator either. Think of it as GNU/Linux/Windows (apologies to Richard Stallman). This guide starts off with Microsoft’s instructions for installing the WSL, and then goes a few steps further by describing how to run graphical Linux applications.
The WannaCry ransomware worm has spread panic and destruction as it infects hundreds of thousands of systems around the world; a rate not seen since the Blaster and Sasser worms of 2003. WannaCry — also known as WannaCrypt, WannaCryptor, WanaCrypt0r, WCry, or WCrypt — leverages vulnerabilities that Microsoft patched in the March MS17-010 Security Bulletin, after taking the unprecedented step of canceling the February Patch Tuesday.
While collecting samples of WannaCry, I found a sample that predates the worm version. The sample was compiled on February 9th, and uploaded to VirusTotal on February 10th. While compile timestamps can be faked, the closeness to the upload date suggests that the compilation timestamp is legitimate.
The headline feature of the new Google Pixel phones is deep integration between the operating system and the Google Assistant AI. By default, the Google Assistant can be activated even when the phone is locked and the display is off, if the device hears the trusted voice say the hot word, “Ok Google”. This also has the effect of unlocking the device, meaning that anyone with a recording of the trusted voice saying “Ok Google” — or even someone with a similar voice — can easily unlock the device.
After upgrading my Nexus 6P on Verizon to the Android 7.1.1 beta, I discovered that Visual Voicemail in the native Android dialer works! You just need to make sure that that basic (free) or premium visual voicemail is active on your line. Voicemail-to-text works too, if you add Premium Visual Voicemail to your line. Unfortunately, there is no sign of Wi-Fi calling support (yet?). HD voice has always worked on the Nexus 6P.
When Google Chrome updated to 53.0.2785.101 on my Windows systems, I encountered an onslaught of alerts from EMET, which was killing chrome.exe processes for EAF+ violations as fast as Chrome kept trying to spawn them (each tab in Chrome is a separate process). Luckily, this problem is easily fixable.
As a growing number of medical facilities are struck by ransomware, the US Department of Health and Human Services (HHS) has published a fact sheet describing how businesses that process electronic Protected Health Information (ePHI) should defend against and respond to ransomware.
Ransomware has become the weapon of choice for financially motivated cybercriminals. Individuals, hospitals, businesses, schools, police departments, and government agencies have all been victims of highly disruptive ransomware, resulting in ransom payments totaling at least $24 million in 2015, according to the DoJ and DHS. It doesn’t take much to start a ransomware campaign, and the returns can be extremely high. Fortunately, the steps to prevent ransomware from succeeding are equally simple and low cost.
By now, you’ve probably heard something about the ongoing legal battle between Apple and the Department of Justice. “DoJ v. Apple” coverage has been abundant, on blogs and TV news shows alike, but in case you haven’t here’s a quick recap. The FBI obtained the work iPhone of Syed Rizwan Farook, who, along with his wife Tashfeen Malik, murdered 14 people in a shooting rampage at a holiday party in San Bernardino, California. The government suspects that iPhone may hold critical information about the couple’s contacts in the weeks leading up to the attacks – contacts that may uncover future plots. They have a warrant, but they can’t access the data on the phone because it is using the strong encryption that comes with iOS 9 and up. Not even Apple can bypass the encryption, at least directly.
