Today, a new “internet sovereignty” law entered into effect in Russia, a law that grants the government the ability to disconnect the entire country from the global internet.

Android bug lets hackers plant malware via NFC beaming

www.zdnet.com/article/android-bug-lets-hackers-plant-malware-via-nfc-beaming/ All Android 8 (Oreo) or later devices are impacted. Google released a patch last month, in October 2019. Google patched last month an Android bug that can let hackers spread malware to a nearby phone via a little-known Android OS feature called NFC beaming. But, in January this year, a security researcher named Y. Shafranovich discovered that apps sent via NFC beaming on Android 8 (Oreo) or later versions would not show this prompt. Instead, the notification would allow the user to install the app with one tap, without any security warning. The CVE-2019-2114 bug resided in the fact that the Android Beam app was also whitelisted, receiving the same level of trust as the official Play Store app. The October 2019 Android patches removed the Android Beam service from the OS whitelist of trusted sources.

Office for Mac Users Warned of Malicious SYLK Files

threatpost.com/office-for-mac-malicious-sylk-files/149823/ Researchers warn XML macros embedded in SYLK files can sidestep Microsoft Office for Mac protections. Microsoft Office for Mac users are being warned that malicious SYLK files are sneaking past endpoint defenses even when the disable all macros without notification is turned on. This leaves systems vulnerable to a remote, unauthenticated attackers who can execute arbitrary code. The warning comes from United States Computer Emergency Readiness Team (US-CERT), which said that symbolic link (SYLK) files can contain dangerous Extensible Markup Language (XML) macros. XML macros can be incorporated into SYLK files, wrote CERT on Friday. Macros in the SYLK format are problematic in that Microsoft Office does not open in Protected View to help protect users.

The DNA database used to find the Golden State Killer is a national security leak waiting to happen

www.technologyreview.com/s/614642/dna-database-gedmatch-golden-state-killer-security-risk-hack/ Heres how spies could use a crowdsourced genetic ancestry service to compromise your privacyeven if youre not a member. A private DNA ancestry database thats been used by police to catch criminals is a security risk from which a nation-state could steal DNA data on a million Americans, according to security researchers. Security flaws in the service, called GEDmatch, not only risk exposing peoples genetic health information but could let an adversary such as China or Russia create a powerful biometric database useful for identifying nearly any American from a DNA sample. GEDMatch, which crowdsources DNA profiles, was created by genealogy enthusiasts to let people search for relatives and is run entirely by volunteers. It shows how a trend toward sharing DNA data online can create privacy risks affecting everyone, even people who dont choose to share their own information. You can replace your credit card number, but you cant replace your genome, says Peter Ney, a postdoctoral researcher in computer science at the University of Washington.

NordVPN users passwords exposed in mass credential-stuffing attacks

arstechnica.com/information-technology/2019/11/nordvpn-users-passwords-exposed-in-mass-credential-stuffing-attacks/ Many of the dumps have been pulled off public webpages, but at least one remains. As many as 2,000 users of NordVPN, the virtual private network service that recently disclosed a server hack that leaked crypto keys, have fallen victim to credential-stuffing attacks that allow unauthorized access to their accounts. In recent weeks, credentials for NordVPN users have circulated on Pastebin and other online forums. They contain the email addresses, plain-text passwords, and expiration dates associated with NordVPN user accounts. I received a list of 753 credentials on Thursday and polled a small sample of users. The passwords listed for all but one were still in use. The one user who had changed their password did so after receiving an unrequested password reset email. It would appear someone who gained unauthorized access was trying to take over the account. Several other people said their accounts had been accessed by unauthorized people
