Twitter: Attack emails drop from 110 million per day to a few thousand

Adopting protocol called DMARC pays big dividends, says Twitter postmaster

There used to be a whopping 110 million attack messages per day spoofing the Twitter domain name as cyber-criminals blasted out fake Twitter e-mail at intended victims to try and fool them into opening dangerous malware-infested links and other scams. But by adopting a messaging authentication protocol called Domain-based Message Authentication, Reporting and Conformance (DMARC), Twitter has seen that number drop to a few thousand.
Lo and behold, it works!
— Twitter postmaster Josh Aberant about DMARC

“Lo and behold, it works,” says Josh Aberant, Twitter’s postmaster in charge of messaging.

DMARC first started about two years ago as a cooperative effort among Google, Microsoft, Facebook, and eBay’s PayPal unit, among others, to combat the scourge of spoofed e-mail that will mimic the domain names of well-known companies.

DMARC works by checking that e-mail truly originated from where it was supposed to. Organizations that support DMARC can monitor for fake e-mail and quarantine or block it. Aberant said Twitter, working with partners Agari and Message Systems, decided to block the bad e-mail that the DMARC protocol identifies.

Aberant says he was shocked when he first saw monitoring that showed there were 110 million attack messages per day abusing the Twitter name.

By combining what’s called “DomainKeys Identified Mail” and the “Sender Policy Framework” with the “Authentication Failure Reporting Format,” DMARC represents the most comprehensive approach to preventing email abuse and protecting sender brands that the Internet industry has offered to date, according to Alec Peterson, chief technology officer at Message Systems.

Because DMARC is supported by the major Internet e-mail service providers, including Google, YahooMail, AOL and Microsoft, Twitter estimates about 90% of Twitter’s user base globally is covered under the DMARC filtering umbrella. Several Chinese ISPs have implemented DMARC as well. But Aberant would like to see more European telecommunications firms and those in the private sector join the DMARC effort to see the momentum build.

Twitter’s DMARC project, which took several months, involved working with a number of outside companies, the business partners such as Salesforce.com, to achieve a kind of “identity alignment” in messaging using the DMARC protocol, says Aberant.

Making sure DMARC authentication works properly means you have to “get a hold of the right people that manage the mail infrastructure,” he points out. Because Salesforce also happened to be using Message Systems, it was a fairly simple configuration change. But in other instances with business partners, the conversion to DMARC can be somewhat more demanding.

Are You Too Old to Land a New IT Job?

Age really is just a number. If you're keeping current on new technologies and advancement, and show a willingness to keep learning and growing, there's no reason it should be an impediment to your job search.

Looking for a job or a promotion and worried that your age might be an impediment? Don't be. Age really is just a number, and especially in IT, that number isn't as important as your accomplishments, your adaptability and willingness to learn.

"It's about being able to demonstrate your accomplishments," says author, career search expert and consultant Rick Gillis. "Most IT firms want to know one of two things: Can you make them money or can you save them money? Then they'll want to hire you, regardless of your age," he says.

Nobody would hire a doctor, for example, who isn't using robotics in his practice, says Gillis. Staying current on new technologies, advancements and methodologies can keep your skill sets relevant and will help you avoid becoming one of those 'former masters of the universe' who've faded into obscurity and can barely turn on their computer, he says.

Too Old for IT

Stay Hip and Up on Tech

"You have to be current. That is key, especially in IT," Gillis says. "I find it disturbing when I speak to clients who are older and they aren't spending time studying, staying hip and up-to-date on new technology advances," he says.

"If you've been looking for a job for six months, you have to realize how much has happened in that time -- learn about emerging technology. Know the terminology. Be able to show that you've added to your knowledge and your skills," Gillis says, and be able to demonstrate how that knowledge and your skills have positively impacted previous employers.

As an example, Gillis cites a former client who was struggling to demonstrate his achievements while searching for a job. The client had one specific job for which he wrote nearly 10,000 lines of code for a bank, but couldn't point to a specific outcome, Gillis says.

"I advised him to take a personal inventory, to reach out to his contact and determine how to quantify what he did," Gillis says. "When we talked to his contact, we were told that the code he wrote was used by the bank to fix some significant security flaws with their ATMs that used to require a lengthy, expensive service call and two people to address," Gillis says.

"It turns out, my client saved the bank more than half a million dollars a year on this expense, and while it did take some time and digging to determine how to quantify his efforts, it was worth it," he says.

But adaptability and using relevant skills and knowledge is a two-way street, says Mike Capone, CIO at human capital management solutions firm ADP. Employers should constantly be looking at the knowledge and skills present in their workforce to see how those accomplishments can help further business goals and even to educate newer, younger or less experienced employees, Capone says.

Adaptability Knows No Age Limit
"Age, in and of itself, doesn't matter, but adaptability does," says Capone. "That's not always a skill you're born with, but it can be learned," especially if companies are tapping into their older employees' skills and knowledge to help educate the younger generation, he says.

To that end, Capone says, ADP makes sure to identify and reward good leadership and tap into older, more experienced employees' domain expertise, and linking them up with younger, newer employees.

"With our younger generation of workers, we force rotational assignments every 18 to 24 months to make sure they are gaining the knowledge and experience of some of our more seasoned people," says Capone. "It's like having that veteran player in the locker room, so to speak, but it's a mutually beneficial exercise. The younger folks keep the older workers current and up to date, while the more experienced folks bring a level of maturity to teams," he says.

"Mentoring is a two-way street, and even when I, as the CIO, am paired up with employees who are much younger and lower on the corporate ladder, I learn something every day," Capone says.

Regardless of the age of employees, companies need to think differently about their workforce to better reap the benefits of existing talents, experience, skills and knowledge, Capone says. Building up your talent pool to take advantage of relevant skills doesn't have to mean bringing in outside consultants or new employees; what you need could be right under your nose.

"It's about change management," Capone says. "And how you incorporate that into your day-to-day operations. Whether you're looking at employees who are 20 or 60, technology, business needs and skills change at a much faster rate right now than they did even five years ago.

It's incumbent on the leadership of the company to manage the talent and take advantage of the skills that you have and the competencies within the domain expertise you need to be successful," he says.

How to save your email archive from a service provider

When your service provider doesn't want you to leave them, how do you get your message archive back?

I recently fielded a query from a Network World reader, a one woman company, who has an email problem: Back around 2006 a computer tech set her up with a hosted exchange server so that she wouldn't lose email in the event of her computer failing, could sync her email with her iPhone, and could have webmail access. Everything was fine for eight years but, alas, the service provider has recently raised their fees from $8 per month to $35 per month.

My reader knows this is tantamount to gouging and that she can get the same service for considerably less (in fact, for nothing if she switches to Google's Gmail) but she has a problem: Tech support at the service provider told her that if she ends the service she'll lose all her archived email and they apparently (and not surprisingly) aren't at all interested in helping her beyond twisting her arm to stay with them.

So, the solution is simple: My reader just needs to make a copy of the contents her hosted exchange service and, as the saying goes, Bob will be her uncle. The answer to her problem is a tool called MailStore Home which works under Windows XP SP3, Vista, Windows 7, and Windows 8.

All she has to do is download, install, and run MailStore Home then, under "Archive Email," configure an email account profile for her provider, and run the profile.

With Gmail I discovered that I had to first get a minimal download completed before trying to archive everything (I know; that makes no sense but after that the archive process worked flawlessly). Downloading from a service like Gmail is not limited by your connection speed; as of writing 90,000 messages has taken something like five hours to download and process but I blame AT&T U-verse's crappy services around 3Mbps for my poor performance).

MailStore provides archiving for:
Internet mailboxes such as Gmail or Yahoo! Mail
Any POP3 and IMAP mailboxes
Microsoft Outlook XP, 2003, 2007, 2010, 2013
Microsoft Outlook Express and Windows Mail
Microsoft Exchange Server 2003, 2007, 2010 and 2013 mailboxes
Microsoft Office 365 (Exchange Online)
Mozilla Thunderbird and SeaMonkey
.EML and other email file formats

Along with that MailStore provides a fast indexing and search feature, the ability to open an archive with a single click, support for huge email archives, and a portable option that can be launched directly from a USB drive.

For business use there's MailStore Server priced at $190 and MailStore Service Provider Edition (price on application).

As an SME/enterprise tool this is a must have. I hope my reader is happy.

IE10 under attack as hackers exploit zero-day bug

FireEye uncovers attacks emanating from a U.S. website just two days after Microsoft issued huge IE patch collection

FireEye today said it had discovered that attackers are actively exploiting a new, unpatched vulnerability in Internet Explorer 10 (IE10).

Microsoft confirmed the Milpitas, Calif. security company's report.

"Microsoft is aware of targeted attacks against Internet Explorer, currently targeting customers using Internet Explorer 10," a Microsoft spokesperson said via email. "We are investigating and we will take appropriate actions to help protect customers."

FireEye's disclosure came just two days after Microsoft patched every edition of IE with a large update that fixed 24 flaws, 15 of which applied to IE10. The IE update, which was not originally on this week's Patch Tuesday slate, was added at the last minute by Microsoft, which said it had completed testing of the repairs in time to make the cut.

The attack code, said FireEye, was hosted on a compromised website based in the U.S. The company called the exploit a "classic drive-by download attack," a term reserved for the most dangerous kind of browser-based assaults, one that only need entice people to a malware-infected site.

According to FireEye, the exploit sidesteps ASLR (address space layout randomization) using Flash ActionScript, an Adobe-owned scripting language most often used on sites that rely on Flash Player to execute content. ASLR is one of Windows' most important anti-exploit technologies.

"Upon successful exploitation, this zero-day attack will download a XOR-encoded payload from a remote server, decode and execute it," FireEye added.

FireEye said that it is "currently collaborating" with Microsoft's security engineers on researching the IE10 vulnerability and the related exploit.

IE10 has been on the downturn for the last four months. Starting in October 2013, Microsoft has been replacing IE10 with the newer IE11 on Windows 8 devices, including PCs and the tablets -- such as Microsoft's own Surface Pro 2 -- that run the full-featured Windows 8 and 8.1 rather than the subset-of-an-OS Windows RT.

Microsoft released IE11 for Windows 7 in November, at which point it was automatically pushed to those machines as a substitute for IE10.

Web metrics firm Net Applications estimated IE10 user share, a rough calculation of the percentage of all Internet users running a specific browser, at 9.3% in January. Most people running IE remain tied to 2009's IE8.

IE10, targeted by attackers exploiting a "zero-day" vulnerability, is on its way out as Microsoft pushes the newer IE11 to Windows 7 and Windows 8 users. Last month, IE10 accounted for about 16% of all versions of Internet Explorer used to browse the Web. (Data: Net Applications.)

Microsoft sets Oct. 31 as stop date for Windows 7 consumer PC sales

But extends end-of-sales date for business PCs running Windows 7 Professional

Microsoft has set Oct. 31 as the end of sales of new consumer-grade Windows 7 PCs, but for now has left open the do-not-sell-after-this-date for business machines.

On the site where it posts such policies, Microsoft now notes that Oct. 31, 2014, is the end-of-sales date for new PCs equipped with Windows 7 Home Basic, Home Premium or Ultimate. All three are consumer-oriented versions of Windows 7; Home Premium has been the overwhelming choice of OEMs (original equipment manufacturers) for consumer systems.

Microsoft's practice, first defined in 2010, is to stop selling an older operating system in retail one year after the launch of its successor, and halt delivery of the previous Windows edition to OEMs two years after a new version launches. The company shipped Windows 8, Windows 7's replacement, in October 2012.

The setting of a deadline for consumer Windows 7 PCs followed a glitch last year when Microsoft named the same Oct. 31 date for all Windows 7 PCs, but then quickly retracted the posting, claiming that the notification had been posted "in error."

Some OEMs, notably Hewlett-Packard, have made headlines for marketing consumer-grade Windows 7 PCs, a sign of the fragmentation of the once-dominant Windows oligarchy, which always pushed the newest at the expense of older editions.

But while it has established an end-of-sales date for consumer PCs with Windows 7 pre-installed, Microsoft has yet to do the same for business PCs.

Microsoft will give a one-year warning before it demands that OEMs stop selling PCs with Windows 7 Professional, the commercial-quality version. Under that rule, Microsoft will allow computer makers such as Lenovo, HP and Dell to continue selling PCs with Windows 7 Professional until at least February 2015.

It's likely that the extension will be much longer.
Windows 7 has become the standard version for businesses, which have spurned Windows 8, largely because of its two-user interface (UI) model, which they consider disruptive to productivity and a needless cost that would require employee retraining.

Most analysts believe that Windows 7 will remain the most popular Microsoft operating system deployed by companies for years to come.

"There's a good chance that enterprises will stay on Windows 7 as long as possible," said Gartner analyst Michael Silver in an October 2013 interview. If his prediction turns out to be accurate, Windows 7 may reprise the stubborn persistence of Windows XP, the nearly-13-year-old OS that Microsoft will retire in April.

Even after Windows 8's launch, Windows 7's user share, a rough measurement of the prevalence of the OS on operational machines, has continued to grow. From October 2012 to January 2014, Windows 7's user share increased nearly 3 percentage points, representing a 6% gain during that period, according to data from analytics company Net Applications.

Some of Windows 7's gains certainly came at the expense of Windows XP, which has fallen more than 11 percentage points, a 28% decline, since October 2012 as users abandoned the old OS.

By making Windows 7 available, Microsoft and its OEMs not only continue to serve customers who want the OS, but make sure that new PC sales do not slump even more dramatically than they have already.

Consumer PC sales have plummeted -- last month Microsoft said sales of consumer-grade Windows licenses fell 20% in the December quarter compared to the same period the year before -- while the Redmond, Wash. company's business line of operating systems grew 12% year-over-year. In effect, enterprise spending kept PC shipments from tanking even more than the 10% contraction the industry experienced in 2013.

Extending Windows 7 Professional's availability on new hardware will also give Microsoft breathing room to continue its retreat from Windows 8's radical shift to a touch-first, tile-based UI, and to roll out a successor that caters even more to customers who rely on keyboard and mouse.

Microsoft is expected to unveil an update to Windows 8.1 this spring, perhaps in April, that will restore several desktop-oriented features and tools. Some reports based on leaked builds of this Windows 8.1 Update 1 have noted that on non-touch devices, the boot-to-desktop option will be enabled by default; if accurate, most users of traditional PCs will skip the colorful, tile-style Start screen. Windows 9 may appear as early as April 2015.

Retail sales of Windows 7 by Microsoft to distributors and customers were officially halted as of Oct. 31, 2013, but that deadline has been meaningless, as online retailers have continued to sell packaged copies, sometimes for years, by restocking through distributors who squirreled away older editions.

As of Saturday, for example, Amazon.com had a plentiful supply of various versions of Windows 7 available, as did technology specialist Newegg.com. The former also listed copies of Windows Vista and even Windows XP for sale through partners.

Even after Microsoft pulls the plug on Windows 7, there will be ways to circumvent the shut-down. Windows 8.1 Pro, the more expensive of the two public editions, includes "downgrade" rights that allow PC owners to legally install an older OS. OEMs and system builders can also use downgrade rights to sell a Windows 8.1 Pro-licensed system, but factory-downgrade it to

Windows 7 Professional before it ships.
And enterprises with volume license agreements will never be at risk of losing access to Windows 7, as they are granted downgrade rights as part of those agreements, and so will be able to purchase, say, Windows 8.1 or Windows 9 PCs in 2015 or 2016, then re-image the machines with Windows 7.

The end-of-sales dates for Windows 7 are not linked in any way to the support schedule for the 2009 operating system. Microsoft will provide free non-security bug fixes and vulnerability patches for Windows 7 until Jan. 13, 2015 -- called "mainstream support" -- and follow that with a five-year stretch of "extended support" during which it will ship free security updates until Jan. 14, 2020.

Microsoft will furnish malware assassin to XP users until mid-2015

Malicious Software Removal Tool (MSRT) to scrub infected XP PCs for more than a year after Microsoft ends patches

Microsoft confirmed on Friday that it will continue to offer its malware scrubbing program to Windows XP users for more than a year after it stops patching the operating system.

"Microsoft's Malicious Software Removal Tool is aligned with the company's anti-malware engines and signatures, and as such the removal tool will continue to be provided for Windows XP through July 14, 2015," a company spokesperson wrote in an email reply to questions.

The Malicious Software Removal Tool (MSRT) is updated monthly as Microsoft targets specific major malware families it believes are the biggest threats at the time. It's distributed through Microsoft's Windows Update service and the business-grade Windows Server Update Service (WSUS) on "Patch Tuesday," the date each month when the company ships security patches and other fixes to customers. The MSRT automatically installs and then runs in a seek-and-destroy mission.

Users can also manually download the MSRT from Microsoft's website.

MSRT is not an antivirus program, but rather a cleanup utility designed to eradicate malware that has already wormed onto a Windows PC. The tool was first released in 2005.

The extension of MSRT's availability for Windows XP was part of Microsoft's decision last Wednesday to offer new anti-malware signatures to XP customers who run the company's free Security Essentials antivirus (AV) software.

Originally, Microsoft had said it would stop shipping Security Essentials' signature updates to XP PCs after April 8. But in a tacit nod to XP's widespread use, Microsoft postponed the cut-off until July 14, 2015.

Microsoft will ship its final public security patches for Windows XP in less than three months, ending nearly 13 years of support for the ultra-successful OS.

Microsoft did not reply Saturday to follow-up questions asking what channels it will use to distribute the malware eraser between April 8, 2014, and July 14, 2015.

If Microsoft continued to deliver the MSRT via Windows Update, the tool would be a valuable weapon in containing infections on Windows XP PCs.

Say a new malware family popped up, or an older one began infecting large numbers of Windows PCs, including those still running XP. Microsoft would be able to revise MSRT so it targets the new or suddenly aggressive malware for detection and deletion, and automatically put it on XP systems. Not only would that keep the remaining XP owners safer, but it would also reduce the number of compromised computers that could in turn be used by hackers to infect machines running the still-supported Vista, Windows 7 and Windows 8 operating systems.

The impact of the MSRT extension would be more muted if Microsoft required users to download the tool themselves. Even so, MSRT is a very popular download -- currently No. 2 on the company's Download Center -- indicating that large numbers of customers seek it out.

Although Microsoft has been urging customers to drop XP before the April 8 deadline for a new OS or PC, millions of machines worldwide will continue to run the aged OS for months and maybe even years to come.

According to metrics company Net Applications, Windows XP's user share -- the percentage of all personal computer owners who went online with that OS -- stood at 29% at the end of December 2014. Computerworld has forecast that at least 25% of all personal computers will be running the operating system at the end of April, and about 20% at the end of this year.

Those numbers were at the root of Microsoft's recent moves to help out XP users: While the company has remained adamant that bug patches will be discontinued after April 8, some cracks in its "Death to XP" policy have appeared, including the continued availability of Security Essentials' signatures and the lifespan extension for the MSRT.

The explanation: Microsoft has decided it best for all concerned -- including itself and its reputation -- that it throw some security bones, if only small ones, to those who can't or won't upgrade from XP.
