Jeff Rivett has worked with and written about computers since the early 1980s. His first computer was an Apple II+, built by his father and heavily customized. Jeff's writing appeared in Computist Magazine in the 1980s, and he created and sold a game utility (Ultimaker 2, reviewed in the December 1983 Washington Apple Pi Journal) to international markets during the same period. Proceeds from writing, software sales, and contract programming gigs paid his way through university, earning him a Bachelor of Science (Computer Science) degree at UWO. Jeff went on to work as a programmer, sysadmin, and manager in various industries. There's more on the About page, and on the Jeff Rivett Consulting site.

No more updates for Security Essentials on Windows XP after April 8

Update 2014Jan16: Microsoft must have decided it could use some positive press, because they just decided to extend Security Essentials support on Windows XP until July 14, 2015.

Microsoft has confirmed that they will stop issuing updates for its anti-malware software Security Essentials on Windows XP systems after support for Windows XP expires on April 8, 2014.

While I’m sure this comes as no surprise to anyone, since Microsoft will no longer be issuing any patches for Windows XP past April 8, it’s an important consideration for anyone who plans to run Windows XP after that date. Anyone doing so should also stop using Security Essentials and install anti-malware software that will continue to receive updates.

If you needed another reason not to visit yahoo.com…

Advertisements containing malware started appearing on yahoo.com on December 30, 2013 – or possibly even earlier. Anyone visiting the site with a browser running an unpatched version of Java risked infecting their computer. If that includes you, a full malware scan of the computer you used should be your next task. One of the following (or both) should do the trick:

If you’ve ever bought from Target (NOT online)…

(Correction: the original title of this post indicated that online shoppers were affected. In fact, according to Target, only customers who used credit cards for in-store purchases are at risk.)

… then you should consider cancelling the credit card you used. Data for as many as 40,000 credit cards, stolen from Target servers in early December, is already appearing on black market sites. Target says card numbers, names and expiry dates were taken, not the associated security codes, so the numbers can’t be used just anywhere. But they will be used, since not all retailers use the security code.

Update 2013Dec29: Brian Krebs of krebsonsecurity.com did some digging and has almost certainly identified one specific individual who is selling card data stolen from Target. His name is Andrey Hodirevski, and he’s been in this shady business for a while in the Ukraine. It’s not clear whether he stole the card data from Target, but he’s selling it so he probably knows who did. It will be interesting to see how this plays out…

Update 2014Jan01: Now Target is saying that PIN codes were stolen along with the rest of the card data. They insist that since the PINs are encrypted, they are of no use, but Target should not have been storing PINs in any form.

Update 2014Jan11: Target now says that additional personal information on 70 million customers was also stolen by the same attackers. This information includes names, mailing addresses, phone numbers and/or e-mail addresses.

Update 2014Mar29: Trustwave, the company that provides PCI compliance services to Target, is being sued by two banks that suffered losses in relation to the Target breach.

Is your Windows XP computer booting slowly?

Windows XP computers with autoupdate enabled are taking longer and longer to boot. Microsoft has discovered a flaw in Windows Update that is slowing down the update process. As the list of available patches for Windows XP has grown over the years, the delays have increased exponentially. Microsoft tried to fix this flaw with recent updates to little effect.

More holiday scam emails

SANS reports on a holiday-themed scam email showing up in inboxes recently. This one purports to be from a major retailer such as Costco or Walmart, and tries to trick the recipient into clicking a link related to a phony undelivered package.

If you receive such an email, just delete it. If you think the message may be legitimate, don’t click the link; contact the retailer by telephone or go to their official web site and contact them using information provided there.

Two posts on the SANS ISC blog dig into the technical details of this scam.

Windows XP NDProxy vulnerability remains unpatched

A serious vulnerability affecting Windows XP and Windows Server 2003 was recently discovered. Microsoft issued advisory 2914486 to warn users about the vulnerability and recommend workarounds, but so far has not released a patch.

This vulnerability is being actively exploited, through the use of a specially-crafted PDF file. Opening such a file on a computer running Windows XP can result in an attacker gaining access to the computer.

The single workaround suggested in advisory 2914486 has some undesirable side-effects, including disabling VPN. But it may be better than the alternative, especially for users who frequently receive and open PDF files on Windows XP computers.

The usual advice applies: exercise extreme caution when browsing the web, clicking links in email, opening email attachments and opening files from unknown sources. When in doubt, don’t do it.

A post on the SANS ISC Diary blog has more, including a warning that these types of vulnerabilities may become much more common after Microsoft stops supporting Windows XP in April 2014. SANS has even coined a term for this event: Winmageddon.

Something changed in Opera 18

My install of Opera 18 updated itself recently, from version 18.0.1284.49 to version 18.0.1284.63. There was no announcement of the change, and there is no release notes page for the new version. The ‘unified’ release notes page for version 18 was last updated on November 18. Is Opera moving toward stealth releases like Firefox? If so, why? While there may be some value in software that silently updates itself, IT staff still need to make intelligent decisions about updating corporate desktops, and they can’t do that without knowing what has changed between versions. The only sensible alternative is to switch to a different browser. Another nail in the coffin for Opera, which is sad.
