Have we here a Facebook Stalker?!

Of great consideration to online privacy are facebook stalkers. If a stalker randomly manages to add a few of your friends and you have your Profile Privacy Settings allowingFriends of Friendsto see everything then your stalker effectively has access to your profile even without having added you.

I’ve now adjusted my privacy settings more strictly and I’ve used theSee how a friend sees your profile:” tool to get an idea of how it changes things.

我的 “BasicInformation I had available toFriends of Friends”. This includesGender, Birthday, Hometown, Political and Religious Views and Relationship Statusaccording to Facebook’s description. You might think it fair that friends of your friends have an idea of how you roll.

But can you trust 所有 your friends anti-stalker spidey-senses?

I think NOT.

I previously had it that friends of friends can see my photos and videos but not much else. I’m thinking of changing that now too.

But wait, there’s More!

Further to this, we should be vigilant offakeFacebook profiles. Stalkers are usually apt enough to create more than one account with fake names. If you block one they create another and attempt to get a glance at your profile once more. I’ve created a friend group calledPrivacy Pls”. This group is limited from being able to see anything other than a very basic page. 这个 “basicview is akin to when you first started using Facebook and didn’t know you could add lots of stuff in there (stuff you later realised you didn’t want anyway).

If someone adds me and I’m not absolutely sure who it is, I add them to myPrivacy Plsgroup. Also if someone adds me and I don’t want to offend them by ignoring their invite I’ll rather add them to this group. Perhaps you feel you have a pervy boss for example.

But Wait! There’s Moreand this time you can do it TOO!

To do this for yourself, go to your Friends page, 点击 “Create New List”, and name it something appropriate – “Privacy Plsin my case. Add the appropriate friends to this list now or add any futuresuspectfriends to the group.

下一个, go to the Profile Privacy Settings page. Underneath each section you will find aEdit Custom Settings” 钮. Click the first one and, at the bottom of the dialog that pops up, you will findExcept these people”. Add yourPrivacy Plsgroup here. Do the same for all the sections you don’t want them to see. When done, use thefriend’s viewtool to confirm what is made available to persons on that list.

And the Friend-of-Friend Stalker?

To prevent yourFriend-of-FriendStalker from being able to see your profile, do yourself a favour and think very critically about what you want potential stalkers to be able to see. Now go change those Privacy Settings toOnly Friends”.

For the Photo Crazy

Check up on your Photo Album Privacy 设置. This is set up much the same as your profile settings. Consider carefully who you want to be able to see which photo albums and adjust the permissions appropriately!

Your Personal Contact Information

最后, check up on your Contact Information: 点击 “Profilebutton towards the top left of the Facebook page to get to your profile. Then click on theInfotab within your profile. When you mouseover the Contact Information section you will see anEditlink pop up on the right. Click this button to start editing your details.

Next to each item you will find alockicon. Click this lock to define further permissions for which friends are able to see the items. You’ve never give your address and phone details to a dodgy stranger you meet on the street. Why do we then go and give it away to everyone on the Internet. I recommend the following:

  • AllowNo one” 上:
    • email address
  • AllowOnly Friends” 上:
    • IM Screen Names
  • Remove completely or allowNo one” 上:
    • mobile phone number
    • landline number
  • Limit the following:
    • address detailsgive your area or suburbbut NOT your full address

Hopefully we don’t all have to learn our lessons the hard way.

P.S. (especially to the guys and gals who have asked) I’ve been extremely busy these last couple of weeks. I have a lot of unedited content I’m hoping to make publishable very soon!

I think the Internet is a scary place. 是, me. Some days I find myself horrified to find the lowliest of criminal bastards trying to steal our livelihoods.

是, people, there are criminals out there and they want your money or they want to use you to make money. What’s even more scary is the lengths to which they are willing to go, even risking YOU. Do not pass Go. Do not collect $200.

I received an email saying that I was being offered a job as aRegional Assistant” 和, though the details weren’t given, the email suggested that it was a legitimate opportunity. I replied asking about where they’d received my details and also about what they would require of me.

Being the skeptic I am, I thought I could spot scammers a mile away. How fortunate that I can still laugh at the idea.

A few hours later, they replied indicating that I’d soon receive further instructions. They’dprobablybeen referred to me by a friend and they had a pile of referrals and so couldn’t specify which friend had recommended me. I waited patiently and left it to the back of my mind. “They’ve probably found a good candidate already and I’ve lost out”, I thought. “How nice that a friend might refer me. Obviously I’m Awesome.” (and daft :-/)

So later on, I receive my email with myfurther instructions”. This is where I finally realised that I was dealing with scammers:

Hi. We’d like to start a trial task. Our customer will make a bank transfer to you this week. Please go to our site <site omitted> to submit the banking details where the transfer will go to. Once we’ve established a good transaction history, you will receive between 2-3 transfers per week (amounts of about R10 000 each except the first trial transfers).
Please confirm that you can start. We don’t send any transfers to your account until we receive confirmation from you.
On Monday you will receive notification, detailed information and instructions regarding the transfers. Thank you and have a lovely weekend.

Say what??? I checked out the web site in question and, without a doubt, this is a money laundering scheme done by professionals. They know what they’re doing and they probably launder millions every month. What’s more is that, inevitably, they will screw you over and get the cops to arrest YOU. These criminals can leave evidence behind implicating you even if all you’ve done is diligently moved money from one place to anotherand kept a small percentage for yourself. 😛

Money laundering is where illegitimate money (stolen, probably) is transferred via third parties to appear more legitimate. You’re an accessory to the crime and, even worse, you’re even likely to be the victim of it. Recognise when an opportunity is too good to be true. I was fooled for a short while. Next up, given that a victim might give out a lot of personal details, the scammers might steal your identity and start to implicate you in fraudulent activities without you ever having done a thing.

If you happen to have already given any details such as the above where they wanted my banking details, contact your bank and inform them of the situation. They will give you the best possible advice on what to do next. If you’ve already responded to the mail but haven’t yet already given them the information they want, don’t reply any further. I’d also suggest calling your local police for further advice.

Why is it that we’re so gullible?

I even considered for a whole second that my colleague had cross-checked the following SPAM before posting it on our IRL noticeboard. Please note that the following text originally had really bad-for-your-eyes fonts and colours. 😉

Urgent Warning from
Cell C, Vodacom公司 & MTN!

[business card of aLegal Representativeof the Special Investigating Unit]

Dear All,
If you receive a phone call on your mobile from any person, saying that, he or she is
a company engineer, or saying that they’re checking your mobile line, and you have
to press # 90 或 #09 or any other number.
End this call immediately without pressing any numbers.
There is a fraud company using a device that once you press #90 或 #09 they can
访问您的“SIM卡’ 卡并拨打电话公司的费用.
这个消息转发给尽可能多的朋友,你可以, 停止它.
所有移动用户的注意,如果你接到一个电话和手机
显示器 (XALAN) 在屏幕上不接听电话, 结束通话立即,
如果接听电话, 你的手机会被病毒感染。.
该病毒会从手机中删除,你的SIM卡都全部IMEI和IMSI信息
卡, 这将让你的手机无法与电话网络连接. 您
将要新买的手机. 该信息已被证实双方摩托罗拉
和诺基亚.
请转发信息这一块
你所有的朋友具有移动.

这让我想到的第一件事情是在页面的顶部表示权威文本. 现在, bear in mind this is on a noticeboardnot my inbox where my anti-spam senses are at their peak.

Who could possibly have the authority to say they’re sending out a notification on behalf of each of South Africa’s tri-opoly of GSM providers? 好, so its someSpecialLegal team that sounds government-type. They’re legitit turns 出 – but they probably don’t have enough time to take my call asking if this is all true. Absolutely everything on the Internet must be true, especially anything I say. 😛

So anyway, now that we’re over the silliness, let’s break this hoax down:

Official Documentation

Bar a business card, which is hardly standard in any industry, there is no official contact information. I’d expect at least a letterhead or a misguided trailing disclaimer.

演讲和语言

实际上有 2 这里通知关于单独的威胁,但它是不是很明显没有充分阅读文本. 这是因为分段的能力和语法都很差. 政府机构通常不发出不良的措辞或paragraphed文档. 还, 为什么不单独发布关于各种威胁的单独通知?

酸橙 绿色??? 的Bleh

有没有链接到更多资源

这种类型的任何警告无疑将提供进一步的信息或宣传的网上存在 机构. 还, 也许他们会喜欢你给有关情况反馈或者他们希望我们进一步报告可疑活动. 但不是. 无. 只是具体代表的名片. 如果这个家伙死, 找到一个更好的工作, 或 树叶 国内?

“有一个诈骗公司 … “

这意味着,他们没有任何线索是谁. 这是一个广泛的和被动的声明. 问每当有人说 “他们” 或 “人谁”. 这是谁 “诈骗公司”? 哪里 “那里”? 为什么没有这条裂缝政府法律团队 (谁有权使用锁子甲传播警告) 让我们知道通过其超级强大的连锁网络邮件?

“这个消息转发给尽可能多的朋友,你可以”

我的, 天啊. 这条线可能已在每一个连锁信 / 社会工程病毒 (我特别的定义) 由于切片面包.

“该信息已经被摩托罗拉和诺基亚证实。”

他们试图阻止你想为自己和尝试独立核实他们的要求. 他们说 “你是愚蠢的检查. 我们已经检查了你. :-ð”. 当然, 事实上, 他们只是想利用我们轻信自然的优势.

“#90 or #09” 和 “XALAN”

There isn’t any way for you to verify this. 再次, question everything. Google’s first page of results is riddled with the wordsCell phone warning hoax”. duh.

If you get a message like the above from your friends, reply and tell them to stop sending spamand maybe give them a link to this page so they know why. 🙂
