How to Be Safe on the Internet

โพสต์5 พ.ค. 2559 03:10โดยสุเมธ ราชประชุม   [ อัปเดต 5 พ.ค. 2559 03:12 ]

          The internet is a staple in many people's everyday lives. It is a great place full of wonderful information, but it is also full of many dangers. The price of banking, shopping, and interacting online might be your personal information. To stay safe on the internet, use the following strategies.

Image titled Be Safe on the Internet Step 1

1
Choose strong passwords. Passwords are like the key to your accounts - only the person with the key can access them. When choosing a password, you want to make sure you choose one that is unique, strong, and not easily guessed by strangers or those close to you. Choose a password that uses letters, numbers, lowercase, uppercase, and characters.[1]
  • Choosing password or 1234 is lazy - and easily guessable. Choosing birthdays of those close to you (or yourself) is probably also not safe. The longer your password is, the harder it will be to guess. Also try leaving out letters, or substituting numbers for letters.
  • Try passwords that reference phrases or things significant only to you. For example, if the name of your beloved childhood goldfish was Sir Bubbles, swap out some of the letters for numbers and you can end up with a very nice password likes1rbubb735 that only you understand.
  • Make sure to choose passwords that are easily remembered or write them down. If you write down your passwords, don't leave them in plain sight. Don't keep them on your computer desk by your computer.
  • Never use the same password for different accounts. If you don’t want to come up with and keep track of dozens of different passwords, come up with a base password (ex. s1rbubb735) and tack a logical modifier onto it for each account. For example, on Amazon, use amzns1rbubb735; on Gmail, use gmails1rbubb735 or for Twitter twitts1rbubb735.
  • It is good practice to change your password every few months.
2
Be mindful when installing programs or agreeing to terms. When you sign up for newsletters, install programs, or agree to anything, read the fine print. If you do not want to receive junk mail or get put on a telemarketer list, look for a small box near the bottom of the page that asks if you want to receive information and offers from other companies. The best sites will have a statement listed that they will not sell your name to other companies (though they may still send you e-mails themselves).
  • Quite frequently, some adware powered downloads, installation packages, malvertising even drive-by virus has the power to provide inexperienced users loads of junkware. Example is, Oracle's Java online installer bundled the installation of Ask Toolbar (aka, Search App by Ask) in its express install mode. For case study, you can review the following image for further references. To stop such an action that aims to promote foistware, one should take highly proactive approaches to keep all other bloatware at bay, e.g., scanning the downloaded executable file via an up-to-date virus protection or an online malware scanner (such as, Google's VirusTotal.com), always performing the "clean" or custom install mode, unchecking all other optional "offers" during the install procedure.
  • Many of these websites can put adware on your computer that tracks your movements and browser habits. Use caution when you come upon those kinds of websites.[2]
  • Some sites require you to give all your information to get the product. Only fill in required fields that are marked with an asterisk (*). If the info box does not have an asterisk, it is optional and you can leave it blank.
3
Do not give out personal details to strangers.  Don't give your full name, address, or phone number to anyone online that you don't trust or know. This is especially important in chat rooms, when negotiating jobs or deals, or making plans through meet-up sites.
  • Be careful when making friends on the internet. Many great friendships can be cultivated through social media, but there are many people who pretend to be someone they are not.
  • Practice caution when dating online. Use only your first name, and never give out specific personal details, no matter how great the other person seems. Don't give money to people you have met online. When you finally decide to meet, always meet in busy public places, like a restaurant or coffee shop. Let other people know where you are going, and never let them pick you up or go back to their place.[3]
  • Giving personal details to strangers not only compromises your accounts and identity, but your physical safety as well. While most people on the internet may be benign and friendly, you have to be aware of the possibility of people using chat rooms, social media, and other websites to collect information that could lead to physical harm at your place of employment or at home.
  • Always check the legitimacy of websites when you shop. If the site has a horrible design or pop ups, it might not be legitimate. Beware of sites that don't allow you to pay through things like PayPal or with a credit card.[4] When shopping on sites likeCraigslist, practice caution.
4
Don't fall prey to phishing scams. Phishing e-mails are messages that appear to be from legitimate companies, such as your bank or stores where you've shopped, that provide links to fake websites and ask for personal information.[5]
  • Always look at the e-mail address. Many senders of online scam e-mails won't have addresses that match the company they claim to represent. Or the address will be altered slightly so that it might not catch the eye of an unmindful person.
  • Beware of phishing e-mail scams claiming to be from eBay, PayPal, a bank, or a company you trust asking for personal or sensitive information. The e-mail may inform you that there is a problem with your account and/or password. There may be a link to click inside. If you get an e-mail like this, don't click on the link. Go directly to the website by typing the URL into your browser.
  • Hover your mouse over suspicious links. At the bottom of your screen, you should see the true URL for the website. Many phishing websites will show a different website in the bottom of your browser or beside your mouse when you hover over the link.[6]
  • Forward any of suspicious e-mails to the company it claims to be sent from. They will confirm whether the e-mail you received was real or not.
  • E-mail programs like Yahoo!, MSN, Hotmail and Gmail will never ask you for your e-mail password. Don't fall for it and give away your password.
5
Keep your eyes peeled for online scams. Online scams crop up everywhere.Online scams crop up everywhere. These scams can pop up in e-mails, tweets, Facebook posts, and many other places. Don't click on links that don't look like a real address or contains a lot of letters and characters that look like gibberish.
  • Never click on pop-ups or e-mails that claim you have won millions of dollars. These are scams.
  • Don't fall prey to e-mails inviting you to play foreign lotteries.[7] Also beware of e-mails which ask you to help someone transfer large sums of money or inheritances out of their country after giving you a long sad story.
6
Limit the information you share on social media. Facebook, Twitter, Google+, Instagram, LinkedIn, and other social media sites are part of most people's every day lives. On Facebook, people post their maiden names, their parents' names, their birthdays, the birthdays of their children, their hometowns, their home address, their home and cell phone numbers, along with myriad other personal information. This information gives anyone with a computer just about every essential piece of information about you.[9] Limit what you share online to protect your identity and privacy.[10]
  • Sharing too many details on social media sites can put you in physical danger as well. Letting the internet know where you live and when you will not be at home may lead to someone breaking into your house - especially when they see all the photos of your new TV, computers, and jewelry. Too many personal details, like your home address, phone number, and daily whereabouts and habits, gives stalkers plenty of information to use against you.
  • Many secure sites, like banking, insurance, loan, and school websites, require security questions. These questions include: "What is your mother's maiden name?", "What is your paternal grandmother/father's name?", "What town did you grow up in?", or "What is your father's birthday?" These answers can be found easily on some people's Facebook pages.
  • Sharing this kind of information can result in identity theft.
  • When choosing security questions, don't choose ones that have answers easily discovered on social media. Choose harder questions only you know the answer to.
7
Have multiple e-mail accounts. It's best to have three accounts. Multiple e-mails help you separate different aspects of your life, gives you official and non-official addresses, and can help you cut down on spam and privacy issues.
  • Have a business e-mail to use for any job-related correspondence. Many times, these are given to your through your place of employment.
  • Have a main personal e-mail address. You can use this one for banking, job hunting, insurance, and other official and personal correspondence. This website can also be given to close friends and family members.
  • Have a junk e-mail. This e-mail can be the one you use to sign up for things on the internet or at stores, restaurants, or other places you might not want to have your main personal address. You can also use this e-mail on social media sites. If spam comes to this e-mail, it won't affect your daily, main personal e-mail or your business e-mail.

Top 5 social media scams to avoid (CNN)

โพสต์26 เม.ย. 2559 01:40โดยสุเมธ ราชประชุม

Scammers have been worming their way into giant social media networks to trick people into giving over their personal and financial information.

Over the past year, the number of phishing attempts on social media networks like Facebook(FB, Tech30), Twitter (TWTR, Tech30), Instagram and LinkedIn (LNKD, Tech30) has exploded 150%, experts at security firm Proofpoint (PFPT) say.

That's because fraudsters can use social media to target hundreds of thousands of people at once, but also blend in with the crowd. They mimic users and their activities, and they take advantage of the way people use social media to deal with business problems.

Here are five of the most cleverly cloaked scams on social media right now, according to Proofpoint:

1. Fake customer service accounts on Twitter

Online criminals set up fake customer service accounts to phish for bank login and password information and other sensitive data. These imposter accounts look very similar to that of real businesses, but are often one character off -- or they include an extra underscore or other keyboard character.

When someone tweets at their bank or example, scam artists will intercept the conversation, and reply to that message with what seems like an authentic answer.

2. Fake comments on popular posts

A popular news story or social media post might generate a lot of comments. Fraudsters like to take advantage of that large audience by adding their own comments with links to other buzzy headlines that lead to credit card phishing scams.

3. Fake live-stream videos

As more media companies start streaming their shows and movies online, scammers are jumping on the bandwagon.

They do things like comment on the Facebook page of a sports team with a link that leads people to believe they can watch a free live stream of a game. But the links lead to a fake website that asks for personal information in order to start the video, which very often doesn't exist.

proofpoint 1

4. Fake online discounts

Fake online discounts work similarly to fake customer service accounts. Schemers will set up social media accounts that look like legit businesses, then pretend to offer a real promotion. In reality, they want to trick people into giving up their personal information.

proofpoint 2

5. Fake online surveys and contests

These tactics have been around for years and are designed to get answers to personal questions that fraudsters can mine and sell later. But criminals embed them into social media posts that often look legit because there's a normal looking profile picture and link, thanks to URL shorteners.

Surprise Ransomware Installed via TeamViewer and Executes from Memory

โพสต์19 เม.ย. 2559 07:44โดยสุเมธ ราชประชุม

Recently a member posted in the forums about a new ransomware that was appending the .surprise extension to encrypted files. When I received the sample, I learned that what I had was an loader that executed a heavily modifiedEDA2 ransomware variant from memory.  That was interesting enough, but soon reports started coming in that the those who were infected were being done so via TeamViewer connections. 

The first ransomware installed via TeamViewer?

As more reports started to come in from Surprise victims, a disturbing trend was discovered. All of the victim's had TeamViewer installed and logs showed that someone connected to their machine using TeamViewer and uploaded the Surprise.exe files to their desktop.


Post showing a TeamViewer LogPost showing a TeamViewer Log

As more logs were posted, it could be seen that there were two TeamViewer IDs that were used by the attackers to upload the ransomware to the computer and execute it. These IDs were 479441239 and 479440875. 

Once it was discovered that TeamViewer was involved, I immediately reached out to TeamViewer support to try and get someone who was part of their security team to either call me or email me so we could discuss this attack.Talking to one of the security team members, I was told that the associated IDs have already been disabled so that they could no longer be used on TeamViewer. I was also told, that it appears that the connections made by the ransomware developer were using the credentials of the victim. TeamViewer felt that some of these accounts may have been included in account dumps, where their credentials were retrieved by the ransomware devs.  

On checking various databases, I did find that more than half of the victims were listed on thehttps://haveibeenpwned.com/ site.

At this point, the Surprise ransomware appeared to have gone dark, so we are unable to investigate this further.

Executing from memory to bypass behavior detection

Another interesting characteristic that we saw in the Surprise Ransomware is that the executable itself does not contain any of the encryption functions or other behavior associated with ransomware programs. Instead it contained another executable that transformed into an encrypted BASE64 encoded string. At runtime this string is decrypted, loaded into memory, and then executed directly from there.

This method is being used to not only try to bypass AV signature definitions, but also behavior detection. Behavior detection is becoming the best way to detect and stop ransomware as signature detections have become easily bypassed.  By trying to offload the encryption functions, typically targeted by behavior analysis, into an file executed from memory, they are hoping it would not be detected. Thankfully, this is not the case.

Below is some partial source code showing how they are using this technique:

Source code for executing a file from memoryExecuting a file from memory

So far this has not helped, as the malicious behavior will still be detected when the ransomware is launched from memory.

The Surprise Ransomware Encryption Process

As already explained, this ransomware is distributed via TeamViewer connections to the victim's computer, which the ransomware developer will use to upload a file called Surprise.exe to the victim's desktop. Once this file is launched, it will decrypt a encrypted BASE64 encoded executable into memory and launch this executable from there.

Once launched, the ransomware will attempt to connect to its Command & Control server where it will send the victim's computer name and username and retrieve a public encryption key. This key will then be used to encrypt a generated AES encryption key, which is then sent back to the Command & Control server.  

The ransomware will now begin to scan the all fixed disks on the computer for files that contain a particular file extension. When it finds a matching file, it will encrypt it with the AES encryption key and append the.surprise extension to it.  The targeted file extensions are:

.asf, .pdf, .xls, .docx, .xlsx, .mp3, .waw, .jpg, .jpeg, .txt, .rtf, .doc, .rar, .zip, .psd, .tif, .wma, .gif, .bmp, .ppt, .pptx, .docm, .xlsm, .pps, .ppsx, .ppd, .eps, .png, .ace, .djvu, .tar, .cdr, .max, .wmv, .avi, .wav, .mp4, .pdd, .php, .aac, .ac3, .amf, .amr, .dwg, .dxf, .accdb, .mod, .tax2013, .tax2014, .oga, .ogg, .pbf, .ra, .raw, .saf, .val, .wave, .wow, .wpk, .3g2, .3gp, .3gp2, .3mm, .amx, .avs, .bik, .dir, .divx, .dvx, .evo, .flv, .qtq, .tch, .rts, .rum, .rv, .scn, .srt, .stx, .svi, .swf, .trp, .vdo, .wm, .wmd, .wmmp, .wmx, .wvx, .xvid, .3d, .3d4, .3df8, .pbs, .adi, .ais, .amu, .arr, .bmc, .bmf, .cag, .cam, .dng, .ink, .jif, .jiff, .jpc, .jpf, .jpw, .mag, .mic, .mip, .msp, .nav, .ncd, .odc, .odi, .opf, .qif, .xwd, .abw, .act, .adt, .aim, .ans, .asc, .ase, .bdp, .bdr, .bib, .boc, .crd, .diz, .dot, .dotm, .dotx, .dvi, .dxe, .mlx, .err, .euc, .faq, .fdr, .fds, .gthr, .idx, .kwd, .lp2, .ltr, .man, .mbox, .msg, .nfo, .now, .odm, .oft, .pwi, .rng, .rtx, .run, .ssa, .text, .unx, .wbk, .wsh, .7z, .arc, .ari, .arj, .car, .cbr, .cbz, .gz, .gzig, .jgz, .pak, .pcv, .puz, .rev, .sdn, .sen, .sfs, .sfx, .sh, .shar, .shr, .sqx, .tbz2, .tg, .tlz, .vsi, .wad, .war, .xpi, .z02, .z04, .zap, .zipx, .zoo, .ipa, .isu, .jar, .js, .udf, .adr, .ap, .aro, .asa, .ascx, .ashx, .asmx, .asp, .indd, .asr, .qbb, .bml, .cer, .cms, .crt, .dap, .htm, .moz, .svr, .url, .wdgt, .abk, .bic, .big, .blp, .bsp, .cgf, .chk, .col, .cty, .dem, .elf, .ff, .gam, .grf, .h3m, .h4r, .iwd, .ldb, .lgp, .lvl, .map, .md3, .mdl, .nds, .pbp, .ppf, .pwf, .pxp, .sad, .sav, .scm, .scx, .sdt, .spr, .sud, .uax, .umx, .unr, .uop, .usa, .usx, .ut2, .ut3, .utc, .utx, .uvx, .uxx, .vmf, .vtf, .w3g, .w3x, .wtd, .wtf, .ccd, .cd, .cso, .disk, .dmg, .dvd, .fcd, .flp, .img, .isz, .mdf, .mds, .nrg, .nri, .vcd, .vhd, .snp, .bkf, .ade, .adpb, .dic, .cch, .ctt, .dal, .ddc, .ddcx, .dex, .dif, .dii, .itdb, .itl, .kmz, .lcd, .lcf, .mbx, .mdn, .odf, .odp, .ods, .pab, .pkb, .pkh, .pot, .potx, .pptm, .psa, .qdf, .qel, .rgn, .rrt, .rsw, .rte, .sdb, .sdc, .sds, .sql, .stt, .tcx, .thmx, .txd, .txf, .upoi, .vmt, .wks, .wmdb, .xl, .xlc, .xlr, .xlsb, .xltx, .ltm, .xlwx, .mcd, .cap, .cc, .cod, .cp, .cpp, .cs, .csi, .dcp, .dcu, .dev, .dob, .dox, .dpk, .dpl, .dpr, .dsk, .dsp, .eql, .ex, .f90, .fla, .for, .fpp, .jav, .java, .lbi, .owl, .pl, .plc, .pli, .pm, .res, .rsrc, .so, .swd, .tpu, .tpx, .tu, .tur, .vc, .yab, .aip, .amxx, .ape, .api, .mxp, .oxt, .qpx, .qtr, .xla, .xlam, .xll, .xlv, .xpt, .cfg, .cwf, .dbb, .slt, .bp2, .bp3, .bpl, .clr, .dbx, .jc, .potm, .ppsm, .prc, .prt, .shw, .std, .ver, .wpl, .xlm, .yps, .1cd, .bck, .html, .bak, .odt, .pst, .log, .mpg, .mpeg, .odb, .wps, .xlk, .mdb, .dxg, .wpd, .wb2, .dbf, .ai, .3fr, .arw, .srf, .sr2, .bay, .crw, .cr2, .dcr, .kdc, .erf, .mef, .mrw, .nef, .nrw, .orf, .raf, .rwl, .rw2, .r3d, .ptx, .pef, .srw, .x3f, .der, .pem, .pfx, .p12, .p7b, .p7c, .jfif, .exif, .rar

When encrypting files it will skip any files that contain the $ symbol or contain the c:\windows and c:\program strings in the filename.

When the ransomware finishes encrypting the computer, it will create 3 files on the desktop.  These files and their contents are:

  • %Desktop%\DECRYPTION_HOWTO.Notepad ransom note.
  • %Desktop%\surprise.bat, which executes the vssadmin.exe Delete Shadows /All /Quiet to remove Shadow Volume Copies.
  • %Desktop%\Encrypted_Files.Notepad file that contains a list of encrypted files

The ransom note for this ransomware states:

What happened to your files ?
All of your files were protected by a strong encryption.
There is no way to decrypt your files without the key.
If your files not important for you just reinstall your system.
If your files is important just email us to discuss the price and how to decrypt your files.

The planet hunter searching for another Earth

โพสต์19 เม.ย. 2559 05:11โดยสุเมธ ราชประชุม



(CNN)"I want to find another Earth. That's what I'm living for."

MIT astrophysicist Sara Seager has been looking at planets beyond our solar system, known as exoplanets, for almost 20 years.
When the first ones were discovered in the 1990s, many questioned the finding and didn't think it was real. But since then, with better technology, we have observed more than 6,000 of them, most of which are giant balls of gas.
Today, the list grows every week.
With so many planets now coming out of hiding, the race is on to identify one that resembles Earth: a rocky world with liquid water just like ours, and suitable to host life.
Seager believes she knows how to make that discovery.

'These aren't planets!'

It's not easy to see exoplanets as you can't just look at them through a telescope. This is due to the blinding light coming from their host stars, which can be very different in size and features compared to our sun. The process is often described as trying to spot a firefly circling a lighthouse, from thousands of miles away.
The first ones were discovered indirectly, in 1995, by just looking at stars to see if they would wobble slightly, responding to the pull of another object's gravity
    At this time, Seager was a graduate student atHarvard searching for a topic for her Ph.D. and she was intrigued by the newborn field of faraway planets.
    "Since the planets were discovered indirectly, most people didn't believe that the discoveries were real. They'd say to me 'Why are you doing this? These aren't planets!'," says Seager.
    The contrarians weren't entirely wrong: the wobble can be caused by other factors such as another star and several planet discoveries have been retracted over time for this reason.
    But then a different technique was found to make their hunt easier, called transit. This is when a planet moves in front of its host star and causes the star's light to dim slightly.
    "One of the planets from the wobble technique showed transit: it went in front of the star at exactly the time it was predicted to and that was basically incontrovertible," says Seager.
    Exoplanets were real.

        No you're not misreading that: in the first ever programme of its kind the US government has launched the initiative to test the strength of its cyber defences.
        Google, Facebook, Microsoft and Yahoo already use so-called "bug bounties" to find and report security problems.
        If hackers discover any major flaws they could get paid.



        The "Hack the Pentagon" scheme has begun and lasts until 12 May.
        The application page says: "If you have information related to security vulnerabilities in the online services listed in scope below, we want to hear from you."
        One senior official speaking to Reuters claimed that thousands of participants were expected to join the initiative.
        The Pentagon already uses its own internal security experts to test its networks, but it is hoped that opening up to vetted outsiders will help spot and remove more weaknesses.
        Security researchers have repeatedly called on the US government to take inspiration from major technology firms and introduce a bug bounty programme.
        Facebook has reportedly paid out more than $3m (more than £2.1m) since its programme was launched in 2011.
        If the Pentagon does introduce financial rewards, it would be the first government-funded initiative of its kind in the world.
        Participants must be US citizens and will have to register and submit to a background check before they are turned loose on the computer system.

    Google is offering new grants in the hope of improving completion rates for computer science degrees.

    The new Google CS Engagement Awards are open to faculty or staff at accredited colleges and universities in the United States, and are designed to support people teaching introductory computer science courses. The aim is to help them retain students to the completion of their course.

     

    Announcing the new grant on both the Google Education and Google Research blogs,  Leslie Yeh Johnson, who is responsible for University Relations says that while there has been an unprecedented increase in enrollment in Computer Science undergraduate programs over the past six years, the number of students who go on to complete undergraduate degrees has not increased in the same ratio. The problem is particularly acute among women and under-represented minorities, according to the 2013 Taulbee Survey.

    Johnson says that while students may begin a CS degree program, retaining students after their first year remains an issue, with one of the strongest factors in the retention of students in undergraduate CS degrees being early exposure to engaging courses and course material. The idea is that if students are given assignments that are meaningful and relevant, or classroom activities that encourage student-to-student interaction, the student stays interested and is more likely to complete their undergraduate CS degree.

    In the hope of improving the percentage of students completing their degree, Google has come up with the CS Engagement Small Grants Program. This is designed to support educators teaching introductory computer science courses in the United States. Google will give unrestricted gifts of $5,000 to the selected applicants’ universities, towards the execution of engaging CS1 or CS2 courses in the 2014-2015 school year. If you’re teaching CS1 and CS2 courses at the post-secondary level, you need to apply for the grant before November 15, 2014. The details are available in the  program's Call for Proposals.
