Amazon adding its own messaging app on the horizon of products

Amazon is reportedly working on its messaging app which majorly focus on group messaging.  Its been named as Anytime.
Anytime will have standard messaging features such as encryption, video support, audio support, and stickers. Amazon says users will be able “encrypt important messages” at a higher level of security, while voice call and audio call will also presumably be private and secure.

How Amazon plans to differentiate, however, is with group messaging.
Anytime is said to have virtually no dependance on phone numbers, unlike competing apps such as WhatsApp. Instead, everything is handled with usernames and Twitter-like  replies. To add a new member to a group message, all you have to do is @ mention them.

There’s also support for location sharing, simultaneous music listening, food ordering, and bill split. Amazon also says that the app will support business chat, a feature being worked on by Facebook and Apple as well.

Amazon has been putting a renewed focus on communication with its Alexa line of devices, and Anytime seems like the perfect service to integrate into the virtual assistants. Most notably, Anytime could be particularly useful on the Echo Show, which offers a screen and camera for more feature-rich communication. Even on the voice-only models, however, you could simply say “Send Sham a message” to easily communicate without lifting a finger.

Avoid being the next victim of wannacry



The list of Microsoft Windows based systems and countries affected by the WannaCry ransomware is growing. The ransomware encrypts files on an attacked system and in turn requests payment in Bitcoins before the files can be decrypted and the system returned back to normal.
The attack is not only limited to personal computers and laptops but also attacks any Windows based server systems.  In the previous posts explained about cryptowall which is a similar in wild during the past.

These days if your mobile or desktop computer is infected what gets installed is likely to be “ransomware” — malicious software that locks your most prized documents, songs and pictures with strong encryption and then requires you to pay for a key to unlock the files.

Here’s some basic advice about where to go, what to do — and what not to do — when you or someone you know gets hit with ransomware.

First off — breathe deep and try not to panic. And don’t pay the ransom.
True, this may be easier said than done: In many cases the ransom note that hijacks the victim’s screen is accompanied by a digital clock ominously ticking down the minutes and seconds from 72 hours. When the timer expires, the ransom demand usually goes up or even doubles. Continue to ignore the demands and your files will be gone, kaput, nil, nyet, zilch, done forever, warns the extortion message.

See, the key objective of ransomware is a psychological one — to instill fear, uncertainty and dread in the victim — and to sow the conclusion in the victim’s mind that any solution for restoring full access to all his files involves paying up. Indeed, paying the ransom is often the easiest, fastest and most complete way of reversing a security mistake, such as failing to patch, opening a random emailed document e.g., or clicking a link that showed up unbidden in instant message. Some of the more advanced and professional ransomware operations have included helpful 24/7 web-based tech support.


Paying up is certainly not the cheapest option. The average ransom demanded is approximately $722, according to an analysis published in September by Trend Micro. Interestingly, Trend found the majority of organizations that get infected by ransomware end up paying the ransom. They also found three-quarters of companies which had not suffered a ransomware infection reported they would not pay up when presented with a data ransom demand. Clearly, people tend to see things differently when they’re the ones in the hot seat. And for those not yet quite confident in the ways of Bitcoin (i.e. most victims), paying up means a crash course in acquiring the virtual currency known as Bitcoin. In the end the extortionist may bargain with you if they’re in a good mood, or if you have a great sob story. But they still want you to know that your choice is a binary one: Pay up, or kiss your sweet files goodbye forever.

This scenario reminds me of the classic short play/silent movie about the villainous landlord and the poor young lady who can’t pay the rent. I imagine the modern version of this play might go something like…


Villain: You MUST pay the ransom!
Victim: I CAN’T pay the ransom!
Villain: You MUST pay the ransom!
Victim: I CAN’T pay the ransom!
Hero: I’ll pay the ransom!
Victim: Oh! My hero!
Villain: Curses! Foiled again!
Assuming you don’t have a recent backup you can restore, fear not: With at least some strains of ransomware, the good guys have already worked out a way to break or sidestep the encryption, and they’ve posted the keys needed to unlock these malware variants free of charge online.
But is the strain that hit your device one that experts already know how to crack? 

WHERE TO GO?

The first place victims should look to find out is nomoreransom.org, a site backed by security firms and cybersecurity organizations in 22 countries. Since its launch on July 25, 2016, nomoreransom.org estimates that it has been able to save 6,000 victims of ransomware more than $2 million USD to date. Last week the group announced the site is now available in Dutch, French, Italian, Portuguese and Russian.
Visit the Crypto Sheriff page at nomoreransom.org, upload one of the files encrypted by the ransomware, and the site will let you know if there is a solution available to unlock all of your files for free.
Another destination that may be useful for ransomware victims is bleepingcomputer.com, which has an excellent Ransomware Help and Tech Support section that is quite useful and may save you a great deal of time and money. But please don’t just create an account here and cry for help. Your best bet is to read the “pinned” notes at the top of that section and follow the instructions carefully.
Chances are, whoever responds to your request will want you to have run a few tools to help identify which strain of ransomware hit your system before agreeing to help. So please be patient and be kind, and remember that if someone decides to help you here they are likely doing so out of their own time and energy.

HOW NOT TO BE THE NEXT RANSOMWARE VICTIM

Regularly backup your data, and make sure the backups are not connected to the computers and networks they are backing up. Most ransomware variants can encrypt files on any attached drives or network files that are also accessible to the host machine (including cloud hosting and cloud-based backups if those passwords are stored on the machine). Bleepingcomputer’s Lawrence Abrams just published this a nice primer called How to Protect and Harden a Computer Against Ransomware.
Many companies are now selling products that claim to block ransomware attacks. Those claims are beyond the scope of this article, but don’t be lulled into thinking these products will always protect you.
Even products that could somehow block all ransomware attacks can’t prevent the biggest reason that ransomware attacks succeed: They trick victims into taking an action that inadvertently undermines the security of their device — be it a smart phone, tablet or desktop computer.
This usually involves clicking a link or downloading and opening a file that arrives in an email or instant message. In either case, it is an action that opens the door to the attacker to download and install malware.

Remember my Three Rules of Online Security:
1: If you didn’t go looking for it, don’t install it.
2: If you installed it, update it.
3: If you no longer need it (or, if it’s become too big of a security risk) get rid of it.

These rules apply no matter what device you use to get online, but I’ll add a few recommendations here that are more device-specific. For desktop users, some of the biggest risks come from insecure browser plugins, as well as malicious Microsoft Office documents and “macros” sent via email and disguised as invoices or other seemingly important, time-sensitive documents.
Microsoft has macros turned off by default in most modern Office versions because they allow attackers to take advantage of resources on the target’s computer that could result in running code on the system. So understand that responding affirmatively to an “Enable Macros?” prompt in an Office document you received externally and were not expecting is extremely risky behavior.
Enterprises can use a variety of group policy changes to harden their defenses against ransomware attacks, such as this one which blocks macros from opening and automatically running in Office programs on Windows 10. Other ransomware-specific group policy guides are here, here and here .

So, what can you do to reverse the effects of the attack without paying the ransom?
If your computer hasn't been affected yet, is there a way to protect against a possible attack?

Prevention Is Better Than Cure
If your Windows based systems haven't been affected yet then that is great as you are in a far better position to prevent against an attack by WannaCry.
The solution to prevent against the ransomware is reletively simple and was actually available a full month before the WannaCry ransomware was released publicly for anyone to use and exploit.
On Friday, May 12, countless organizations around the world began fending off attacks from a ransomware strain variously known as WannaCrypt, WanaDecrypt and Wanna.Cry. Ransomware encrypts a victim’s documents, images, music and other files unless the victim pays for a key to unlock them.
It quickly became apparent that Wanna was spreading with the help of a file-sharing vulnerability in Windows. Microsoft issued a patch to fix this flaw back in March 2017, but organizations running older, unsupported versions of Windows (such as Windows XP) were unable to apply the update because Microsoft no longer supplies security patches for those versions of Windows.
The software giant today made an exception to that policy after it became clear that many organizations hit hardest by Wanna were those still running older, unsupported versions of Windows.
“Seeing businesses and individuals affected by cyberattacks, such as the ones reported today, was painful,” wrote Phillip Misner, principal security group manager at the Microsoft Security Response Center. “Microsoft worked throughout the day to ensure we understood the attack and were taking all possible actions to protect our customers.”
The update to address the file-sharing bug that Wanna is using to spread is now available for Windows XP, Windows 8, and Windows Server 2003 via the links at the bottom of this advisory.
On Friday, at least 16 hospitals in the United Kingdom were forced to divert emergency patients after computer systems there were infected with Wanna. According to multiple stories in the British media, approximately 90 percent of care facilities in the U.K.’s National Health Service are still using Windows XP – a 16-year-old operating system.
All you have to do is to install the latest Microsoft Windows security patch which is mentioned in this March 2017 Microsoft Security Bullettin. You can download the patch here and follow the instructions to install it and protect your system against a potential WannaCry ransomware attack. The move is a bid to slow the spread of the WanaCrypt ransomware strain that infected tens of thousands of Windows computers virtually overnight this week.

Reversing The Damage
The best advice so far seems to come from Kaspersky Labs who have said they are also working on the possibility of creating a decryption tool to help victims.
Firstly, as advised by Kaspersky, you need to ensure that your Windows system is running any form of endpoint security and if running Kaspersky tools, ensure that the the Kaspersky System Watcher component is available on your system.

Kasperky System Watcher has the ability to "rollback the changes done by ransomware in the event that a malicious sample managed to bypass other defenses".
Below are the steps to follow to try and recover the effects of the WannaCry ransomware:
1. Make sure that all hosts are running and have enabled endpoint security solutions.
2. Install the official patch (MS17-010) from Microsoft, which closes the affected SMB Server vulnerability used in this attack.
3. Ensure that Kaspersky Lab products have the System Watcher component enabled.
4. Scan all systems. After detecting the malware attack as MEM:Trojan.Win64.EquationDrug.gen, reboot the system. Once again, make sure MS17-010 patches are installed.
