There are good reasons to be suspicious of e-mail. Some e-mail messages might be phishing scams, some might carry viruses. Images in spam e-mail might turn out to be pornographic, or to include Web beacons, which can be adapted to secretly send a message back to the sender. Follow these guidelines to help protect yourself when suspicious mail shows up in your Inbox. 1. Do not respond — and don’t open junk mail If an e-mail looks suspicious, don’t risk your personal information by responding to it. Delete junk e-mail messages without opening them. Sometimes even opening spam can alert spammers or put an unprotected computer at risk. Don’t reply to e-mail unless you’re certain that the message comes from a legitimate source. This includes not responding to messages that offer an option to “Remove me from your list.” Do not “unsubscribe” unless the mail is from a known or trusted sender. Use the junk mail tools in your e-mail program. Gmail, Outlook, Yahoo, and most providers let you mark messages as spam or phishing, which trains their filters and blocks the sender. 2. Approach links with caution Links in phishing e-mail messages often take you to phony sites that encourage you to transmit personal or financial information to con artists. Avoid clicking a link in an e-mail message unless you are sure of the real target address, or URL. ...

A few clues can help you spot fraudulent e-mail messages or links within them. What does a phishing e-mail look like? Phishing e-mail messages are designed to steal your identity. They ask for personal data, or direct you to Web sites or phone numbers to call where they ask you to provide personal data. Phishing e-mail messages take a number of forms: They might appear to come from your bank or financial institution, a company you regularly do business with, such as Microsoft, or from your social networking site. They might appear to be from someone you know. Spear phishing is a targeted form of phishing in which an e-mail message might look like it comes from your employer, or from a colleague who might send an e-mail message to everyone in the company, such as the head of human resources or IT. They might ask you to make a phone call. Phone phishing (vishing) scams direct you to call a customer support phone number. A person or an audio response unit waits to take your account number, personal identification number, password, or other valuable personal data. They might include official-looking logos and other identifying information taken directly from legitimate Web sites, and they might include convincing details about your personal information that scammers found on your social networking pages. They might include links to spoofed Web sites where you are asked to enter personal information. To make these messages look even more legitimate, scam artists may place a link that appears to go to the legitimate Web site, but actually takes you to a phony scam site or a pop-up window that looks exactly like the official site. ...

Phishing (pronounced “fishing”) is a type of online identity theft. It uses e-mail, text messages, and fraudulent Web sites that are designed to steal your personal data or information such as credit card numbers, passwords, account data, or other information. Con artists might send millions of fraudulent messages with links to fraudulent Web sites that appear to come from Web sites you trust, like your bank or credit card company, and request that you provide personal information. Criminals can use this information for many different types of fraud, such as to steal money from your account, to open new accounts in your name, or to obtain official documents using your identity. ...

In computer security, a sandbox is a security mechanism for separating running programs. It is often used to execute untested code, or untrusted programs from unverified third-parties, suppliers and untrusted users. I recommend Sandboxie for daily use on Windows — the open-source fork maintained by the Sandboxie-Plus community after the original project was discontinued. The sandbox typically provides a tightly-controlled set of resources for guest programs to run in, such as scratch space on disk and memory. Network access, the ability to inspect the host system or read from input devices are usually disallowed or heavily restricted. In this sense, sandboxes are a specific example of virtualization. ...

Step 1: Report the incident Contact the following authorities: Your credit card company, if you have given your credit card information. The sooner an organization knows your account may have been compromised, the easier it will be for them to help protect you. The company that you believe was forged.

After Adobe absorbed Macromedia, Dreamweaver remained the default tool for many small teams building corporate sites, portfolios, and internal portals. Dreamweaver CS4 adds better CSS tooling, Live View powered by WebKit, and closer ties to the Adobe stack — but the hard part is still the same: keeping sites maintainable after launch. What CS4 Improved Live View renders pages with a WebKit engine — closer to Safari and Chrome than the old Design view approximation Stronger CSS panel workflows for designers who do not want to hand-write every rule Better code hinting for PHP and JavaScript Integration hooks for Photoshop comps and Bridge asset management Spry framework widgets for menus and form validation — use sparingly Subversion integration for teams finally moving off shared folders Live View reduces “upload and pray” cycles. You still need to test in IE7 and Firefox 3 — WebKit is not the whole audience. ...

If Sysinternals shows you what is running, OllyDbg shows you what a program is thinking — one x86 instruction at a time. In 2008 it is the standard debugger for 32-bit Windows binaries: unpack a crackme, trace a malware sample in a lab, or understand why an installer behaves oddly when the vendor will not answer support calls. OllyDbg 1.10 is the version most people use. It is freeware, debugger-only (no disassembler license debates), and extensible with plugins. ...

Google Chrome arrived yesterday as a Windows beta with a comic explaining multi-process tabs and a reputation for speed. Another browser is the last thing some people wanted. For web developers and security folks, it is a big signal: the rendering engine wars are back. Mac and Linux versions do not exist yet. This is a Windows-only beta — but the design choices are worth studying regardless of platform. What Is Different Separate processes per tab — one crash does not take down everything Sandboxing ambitions — harder for web content to touch the system V8 JavaScript engine — fast enough to change how web apps feel in the browser Minimal UI — the address bar doubles as search, fitting Google’s habits Incognito mode — private browsing without digging through menus Silent auto-update — patches ship without a user-facing version bump Chrome uses WebKit for rendering — the same engine family as Safari — with Google’s own V8 replacing JavaScriptCore for script execution. ...

By late 2007, a lot of “enterprise” work still happens on small internal web apps: timesheets, inventory lookups, simple ticketing, phone directories. You do not always need Java or .NET. Sometimes you need PHP, MySQL, and a Windows server that the IT team can actually maintain. That is common in broadcasting, education, and mid-size offices — anywhere IT support sits close to the users and budgets are tight. Why Internal Tools Matter Desktop apps are expensive to deploy. Browser tools win when: ...
