Incident report on memory leak caused by Cloudflare parser bug

This is quite serious. A lot of small (and not so small) websites uses Cloudflare for CDN and DDoS protection. The issue reported by Google’s Project Zero team indicates that a bug in Cloudflare’s processing causes potentially sensitive information to be leaked. This is already bad, but it is made worse due to caching servers keeping a copy of those information. Someone is compiling a list of notable websites affected. You are advised to change your passwords on those affected websites.

Last Friday, Tavis Ormandy from Google’s Project Zero contacted Cloudflare to report a security problem with our edge servers. He was seeing corrupted web pages being returned by some HTTP requests run through Cloudflare. It turned out that in some unusual circumstances, which I’ll detail below, our edge

Hackers Attack Every 39 Seconds | 2017-02-10 | Security Magazine

Not surprising to anyone who has or had administered any servers that has open ports on the Internet. That is why the minimum you can do is to limit the attack surface by restricting Internet-facing ports, and using software like fail2ban to automatically ban attack attempts.

A Clark School study at the University of Maryland is one of the first to quantify the near-constant rate of hacker attacks of computers with Internet access—every 39 seconds on average—and the non-secure usernames and passwords we use that give attackers more chance of success.

Hackers Have Stolen Millions Of Dollars In Bitcoin — Using Only Phone Numbers

Often your phone is the weakest link to all of your online and sometimes offline identity. Someone wrote a detailed and lengthy advisory on how to protect yourself against such attacks.

The security loophole these hackers are milking can be used against anyone who uses their phone number for security for services as common as Google, iCloud, a plethora of banks, PayPal, Dropbox, Evernote, Facebook, Twitter, and many others. The hackers have infiltrated bank accounts and tried to initiate wire transfers; used credit cards to rack up charges; gotten into Dropbox accounts containing copies of passports, credit cards and tax returns; and extorted victims using incriminating information found in their email accounts.

But the hackings should scare anyone with a mobile phone, an email account or an online bank account.

Vizio tracked and sold your TV viewing habits without consent (updated)

The tl;dr version: Smart TV spies on your viewing habits. Well, the incentive for doing this is too great. Such detailed viewing habits can be a minefield for advertisers and marketing companies. Vizio was caught by FTC because it’s too brazen. Others may follow.

According to the original complaint filed by the FTC and New Jersey AG, the company worked with a third party to build smart TVs that could capture “second-by-second” viewing information about what’s on the screen. That includes details on content from cable, internet, set-top boxes, DVD players, over-the-air broadcasts and other streaming devices.

Hotel ransomed by hackers as guests locked in rooms

The tide of ransomware is gaining momentum. We will definitely see a lot more high profile cases of ransomware in 2017. As cyber-physical barrier becomes more fluid, so too will cyberattacks.

One of Europe’s top hotels has admitted they had to pay thousands in Bitcoin ransom to cybercriminals who managed to hack their electronic key system, locking hundreds of guests in or out of their rooms until the money was paid.

Eyes Above The Waves: Disable Your Antivirus Software (Except Microsoft’s)

Hear, hear. I’ve always regarding AV software by the usual suspects as bloatware and it’s always the first thing I uninstall on new machines that came with them. It’s ironic how the public – and shockingly some IT professionals – gives AV vendors a free pass just because they market themselves as a panacea to the malware out there.

At best, there is negligible evidence that major non-MS AV products give a net improvement in security. More likely, they hurt security significantly; for example, see bugs in AV products listed in Google’s Project Zero. These bugs indicate that not only do these products open many attack vectors, but in general their developers do not follow standard security practices. (Microsoft, on the other hand, is generally competent.)

AWS and Azure in Plain English

If you are not an architect-level user of AWS you will probably be lost in the ever growing list of AWS services. The non-obvious names (Cognito, Athena, anyone?) for the services doesn’t help. Now someone is attempting to provide a – sometimes tongue-in-cheek – explanation of those services. Well, it’s not exactly plain english, but good attempt anyway. An Azure version is also available.

Wide Impact: Highly Effective Gmail Phishing Technique Being Exploited

Phishing attacks are getting more creative, relying on moments of weakness in human perception. The tried-and-tested phishing method normally includes the domain name of the target site as part of the URL (eg. paypal.com-privacyprotection.com) and hope that the user doesn’t notice the actual domain (com-privacyprotection.com). This method takes it to another level ‘cos you will see the actual URL of the target site.

A new phishing technique that affects GMail and other services and how to protect yourself.

Ransomware Spreading Onto Smart TVs, Is A Pain To Fix

Oh yes. Smart TVs. We should really be looking at it as a computer with a large screen – which happens to be running Android OS most of the time. Needless to say malware/ransomware that “works” for existing Android devices will seamlessly work in the Smart TV.

Streaming TV has been a boon for consumers. Programming is everywhere, right at our fingertips, as soon as we get our screens online. But that connectivity comes with a big…

Online databases dropping like flies, with >10,000 falling to ransomware

The first story of ransomware in 2017. We’re likely to see more stories about ransomware given its lucrativeness – people/organizations are quite willing to pay a “small” fee to get their data back. This in turns encourages more cybercriminals to turn to ransomware. The rise of cryptocurrencies like Bitcoin also helps to facilitate this as it makes it hard to trace the perpetrators.

More than 10,000 website databases have been taken hostage in recent days by attackers who are demanding hefty ransoms for the data to be restored, a security researcher said Friday.
