Symantec is observing an increase in spam containing URLs. On May 16, URL spam volume increased by 12% from 84% to 96% and since then the URL spam volume fluctuated between 95% and 99%. That means 95% of the spam messages delivered during this period has one or more URLs in it.
Figure 1. URL spam message volume
During this period, .ru was the most used top-level domain (TLD). As illustrated in Figure 2, it is interesting to note a drop in .ru spam and a simultaneous rise in .com and .pw spam. Over 73% of the URL spam contained the .ru, .com, or .pw TLDs.

Table 1. Spam volume of top 5 TLDs that contributed to total URL spam
We are observing an increasing use of shortened URLs and free Web domains with the .ru TLD. The spam examples seen are mainly hit-and-run (a.k.a. snowshoe) spam. The call to action URL in the spam message leads to fake offers or online pharmacy stores.
Below are the Subject lines that may be seen in spam emails.
Subject: Ends Today! Buy One, Get One Free
Subject: 48 Hours Only | Free Shipping!
Subject: FREE LIFETIME PASS – WHENEVER YOU WANT
Subject: Are you dreaming about good health?
Subject: Satisfy your girl fully
Subject: Win your lady’s addiction
Subject: Present your women real care
Subject: You need Ukrainian woman with beautiful eyes that are ready to talk to private theme?
Figure 3. URL spam message
This sudden rise in URL spam volume was seen in December 2012 and January this year when holiday season spam and year-end spam was on the rise. Symantec will continue to monitor this uptick in spam containing URLs and will keep our customers protected with additional filters to block these attacks.
現在、電子メールアカウントは単に電子メールを送受信するためだけのものではありません。Microsoft 社や Google 社など、無料サービスプロバイダの多くが、電子メールアカウントに付随したサービスを数多く提供しています。こうしたアカウントにアクセスできれば、そこにアップロードされたプライベート写真などにもアクセスできるようになるかもしれません。攻撃者が電子メールアカウントに侵入して裸の写真などを見つけ、持ち主を恐喝したという事件も何件か起こっています。ほとんどの人は、そんな写真をアップロードするほど愚かではないでしょう。しかし、さまざまなサービスを備えた現在の統合クラウドストレージでは、パスワードファイル、ライセンスファイル、税務記録、パスポートのスキャン画像、仕事の書類など、あらゆる種類のファイルが電子メールアカウントの下に格納されている可能性があります。
Phishers are trying everything they can to improve their chances of harvesting user credentials. They are known for experimenting with different fake social media applications in a desperate move to lure users. Recently, we found a few examples of some…
Natural disasters, like tornadoes and earthquakes, are quite common in the United States of America. Unfortunately, the Oklahoma City suburb of Moore experienced a violent tornado on Monday, May 20, that sadly resulted in dozens of casualties. Spammers…
Grum, one of the largest spamming botnets, suspected to be responsible for over 17% of worldwide spam (as described here), which was “killed” in July 2012, still lives. We have been tracking its activity since January 2013. We can confirm spiderlab’s doubts about the grum killing published in March 2013. The following article provides some […]
It’s time to stop and take a moment to consider cyber security, says the Australian Government. Once a year, the government gets together in partnerships with industry, the community, and consumer organisations to help make people aware of basic steps they can and should do to protect their personal and financial information.
This year’s theme on their Website is “Our Shared Responsibility”. I encourage you all to go out and look at their website, where they help distill a lot of activities down to the basic 10.(With commentary by me.)
Install and update your security software and set it to scan regularly. If you’re broke, there are free A/V options from Microsoft, AVG, and Avast. Install one of these at minimum! Then as soon as you can, upgrade to a top-rated A/V like Norton.
Turn on automatic updates on all your software, particularly your operating system and applications. Just do it. Microsoft pushes updates on the second Tuesday of every month. Get used to a reboot when required.
Use strong passwords and different passwords for different uses. Don’t use the same password for your bank as for email and Facebook. And change them at least quarterly!
Stop and think before you click on links and attachments. Most infections come in through ‘social engineering’ – that is, convincing people to open up a file or click a link with a virus payload.
Take care when buying online – research the supplier and use a safe payment method. Look for the green bar, and the Norton Secured Seal!
Only download “apps” from reputable publishers and read all permission requests.
Regularly check your privacy settings on social networking sites. Sharing isn’t always caring!
Stop and think before you post any photos or financial information online. We saw people posting pictures of their receipts and checks on FB once. Don’t be crazy!
Talk with your child about staying safe online, including on their smart phone or mobile device. Teach them never to share their passwords with friends, and not to save their logins on unfamiliar machines. Show them how to check the No button!
Report or talk to someone if you feel uncomfortable or threatened online. Cyber bullying is a crime! If someone is trying to intimidate you or your family members, report it immediately to the police.
The site didn’t list it, but I believe strongly in power-on password protection in case your computer or phone is stolen. I use the ‘find my phone’ app for tracking it to the bad guy who might steal it. And back up your files securely – encrypted online or on a back-up hard drive.
Be vigilant about your own protection, because the cyber criminals are certainly vigilant about finding easy targets.
Bitcoin is a virtual decentralized currency that was created in 2009 by developer Satoshi Nakamoto, who described the currency in a paper. Recently Bitcoin has gotten lots of attention. In early 2013, the prices reached a high of US$265 per Bitcoin. The following chart shows the currency’s historical price: Because Bitcoin is a virtual Read more…
