How Not to Buy Tax Software

February 22, 2012

Scott Henry scoured the Web for a good deal on buying TurboTax. His search ended at Blvdsoftware.com, which advertised a great price and an instant download. But when it came time to install the software, Henry began to have misgivings about the purchase, and reached out KrebsOnSecurity for a gut-check on whether trusting the software with his tax information was a wise move.

Five days after Henry purchased the product, blvdsoftware.com vanished from the Internet.

Flash Player Update Nixes Zero-Day Flaw

February 15, 2012

Adobe has issued a critical security update for its ubiquitous Flash Player software. The patch plugs at least seven security holes, including one reported by Google that is already being used to trick users into clicking on malicious links delivered via email.

In an advisory released Wednesday afternoon, Adobe warned that one of the flaws — a cross-site scripting vulnerability (CVE-2012-0767) reported by Google — was being used in the wild in active, targeted attacks designed to trick users into clicking on a malicious link delivered in an email message. The company said the flaw could be used to take actions on a user’s behalf on any website or webmail provider, if the user visits a malicious website. A spokesperson for the company said this particular attack only works against Internet Explorer on Windows.

Microsoft AV Flags Google.com as ‘Blacole’ Malware

February 14, 2012

Computers running Microsoft’s antivirus and security software may be flagging google.com — the world’s most-visited Web site — as malicious, apparently due to a faulty Valentine’s Day security update shipped by Microsoft.

Not long after Microsoft released software updates to fix at least 21 security holes in its Windows operating system and other software, the company’s Technet support forums lit up with complaints about Internet Explorer sounding the malware alarm when users visited google.com.

The alerts appear to be the result of a “false positive” detection shipped to users of Microsoft’s antivirus and security products, most notably its Forefront technology and free “Security Essentials” antivirus software.

Critical Fixes from Microsoft, Adobe

February 14, 2012

If you use Microsoft Windows, it’s time again to get patched: Microsoft today issued nine updates to fix at least 21 security holes in its products. Separately, Adobe released a critical update that addresses nine vulnerabilities in its Shockwave Player software.

Six of the patches earned Microsoft’s most dire “critical” rating, meaning that miscreants and malware can leverage the flaws to hijack vulnerable systems remotely without any help from the user. At least four of the vulnerabilities were publicly disclosed prior to the release of these patches.

Forcing Flash to Play in the Sandbox

February 7, 2012

Adobe has released a public beta version of its Flash Player software for Firefox that forces the program to run in a heightened security mode or “sandbox” designed to block attacks that target vulnerabilities in the software.

Sandboxing is an established security mechanism that runs the targeted application in a confined environment that blocks specific actions by that app, such as installing or deleting files, or modifying system information. The same technology has been built into the latest versions of Adobe Reader X, and it has been enabled for some time in Google Chrome, which contains its own integrated version of Flash. But this is the first time sandboxing has been offered in a public version of Flash for Firefox.

Warnings About Windows Exploit, pcAnywhere

January 27, 2012

Security experts have spotted drive-by malware attacks exploiting a critical security hole in Windows that Microsoft recently addressed with a software patch. Separately, Symantec is warning users of its pcAnywhere remote administration tool to either update or remove the program, citing a recent data breach at the security firm that the company said could help attackers find holes in the aging software title.

‘Citadel’ Trojan Touts Trouble-Ticket System

January 23, 2012

Underground hacker forums are full of complaints from users angry that a developer of some popular banking Trojan or bot program has stopped supporting his product, stranding buyers with buggy botnets. Now, the proprietors of a new ZeuS Trojan variant are marketing their malware as the first offering that lets customers file bug reports, suggest and vote on new features in upcoming versions, and track trouble tickets that can be worked on by the developers and fellow users alike.

New Tools Bypass Wireless Router Security

December 29, 2011

Security researchers have released new tools that can bypass the encryption used to protect many types of wireless routers. Ironically, the tools take advantage of design flaws in a technology pushed by the wireless industry that was intended to make the security features of modern routers easier to use.

At issue is a technology that ships with most modern consumer wireless routers, called “Wi-Fi Protected Setup” (WPS). According to the Wi-Fi Alliance, an industry group, WPS is “designed to ease the task of setting up and configuring security on wireless local area networks. WPS enables typical users who possess little understanding of traditional Wi-Fi configuration and security settings to automatically configure new wireless networks, add new devices and enable security.”

Amnesty International Site Serving Java Exploit

December 22, 2011

Amnesty International’s homepage in the United Kingdom is hacked and is currently serving malware that exploits a recently-patched vulnerability in Java. Security experts say the attack may be opportunistic, or it may be part of a more nefarious scheme to target human rights workers.
