ATT Phishing scam

I received a call from a client this morning about an email from ATT that he was worried about. I asked him to forward the email to me so I could take a look at it.

This looks really good, but something doesn’t smell right. Check out that return address- that doesn’t have anything to do with ATT…and if you hover your mouse over the link itself, you can see it sends you to a site I don’t recognize AT ALL.

This email  is absolutely 100% a scam. It’s based on an actual notification ATT sent out in January – they copied and pasted some of the text  to make it look legit, and then changed dates (the actual email this is based on went out in January and referenced Jan 30th, not May 11th) and links and stuff to redirect you to a phishing site. Be on the lookout for these. Once the scammers find a new formula, they like to push it hard for a few months. If you see an email like this from “att“, Just delete, or call me (440-777-7881) if you have a question!

Modify the registry to deactivate Windows

 

Problem:

The windows activation windows keeps poping up even  though windows says it’s been activated. This is frequently caused by someone using an activation crack, or by the wpa.dbl and wpa.bak files courrupting. Sometimes also happens after a repair installation of windows.

Before we can legitimatly (re)activate windows we first must de-activate it.

Solution:

In Registry Editor, expand My Computer, and then expand HKEY_LOCAL_MACHINE.
Expand SOFTWARE, and then expand Microsoft.
Expand Windows NT, and then expand CurrentVersion.
Under CurrentVersion, click WPAEvents.
In the right pane (topic area) of Registry Editor, right-click OOBETimer, and then click Modify.
Click to put the pointer in the Value data box. Then, modify any character that appears in the Value data box.
Click OK.

iOS 11.3 and 3D Touch Problems

What to Know About iOS 11.3 and 3D Touch Problems

Ah, iOS, our old nemesis. Every time Apple comes swooping in with bug fixes, it sprinkles in a few new ones. With the introduction of iOS 11.3, reports are flooding in that upgrading disables 3D Touch on iPhones. That goes for new and repaired phones.

Gadget Hacks reports this is a prominent bug on the iPhone 7 Plus, iPhone 8 Plus, and iPhone X, but that it may affect others, too. The silver lining is this bug doesn’t brick the phone. It temporarily disables 3D Touch shortly upon unlocking the screen with Touch ID or Face ID. It may also cause lock screen notifications to malfunction.

Some sources recommend running through a gauntlet of soft fixes like cleaning the home button, disabling 3D Touch, force restarting, and re-enabling 3D Touch, or re-adding fingerprints, but don’t count on any of those steps to fix the problem.

What’s the real solution?

If it’s not too late, don’t upgrade to iOS 11.3.

If it is too late, try downgrading to the previous version of iOS to ride out the bug fixes in safety.

If it’s too late, and the bug is more severe than expected, the issue may be hardware-related.

Expect questions from customers

This is a pressing concern because iOS 11.3 is a tempting upgrade. On top of performance and security enhancements, it promises a fix to Apple’s infamous battery throttling (in iPhones 6 through 7 Plus) by sharing battery performance stats and allowing users to turn off throttling.

For now, educate as many customers as possible on the risks of upgrading to iOS 11.3 until a bug fix comes along. It won’t be worth the enhancements if 3D Touch goes away.

Contact us with questions and concerns

iOS updates commonly cause glitches on devices old and new, but if you experience numerous problems with our iPhone replacement screens regarding this upgrade, please contact us and we will assist you to make the situation right.

MTU Test

 

Problem:

How to check optimal WAN MTU settings.

Solution:

The primary reason is that in most if not all cases if you send packets at 1500 they will need to be fragmented resulting in degradation of performance. I would not reccomend changing the MTU settings without first checking the optimal settings for your environment, do not just take the word of your ISP, they are making a generalized statement that covers the masses, it is not a total optomization.

Checking is easy to do. First make sure that your MTU setting is in fact 1500 or the test is compromised and will result in a number that is too low.

The command is to see the largest packet is “ping -f -l XXXX www.XXX.com” -f -l forces the ping packet size to be what you specify, any size to lage returns a reply that the packet needed to be fragmented.

-l is a lowwercase L
XXXX is mtu speeds start at 1500 and decrease in multiples of 10 (1500, 1490, 1480 etc…) until you get a ping result, then increase in multiples of 1 until you again get the reply that the packets needed to be fragmented. The highest numbet that did not have to be fragmented is your highest optimal number. I would actually suggest decreasing it by 2. So if 1464 is the highest you could send without fragmentation set the MTU to 1462.

and XXX is a website of your choosing.
