Adobe and Microsoft today each separately released security updates to remedy zero-day bugs and other critical vulnerabilities in their software. Adobe issued fixes for its Flash and Shockwave players, while Microsoft pushed out 11 updates addressing addressing at least two dozen flaws in Windows and other software.
Last week’s article about how to prevent CryptoLocker ransomware attacks generated quite a bit of feedback and lots of questions from readers. For some answers — and since the malware itself has morphed significantly in just a few day’s time — I turned to Lawrence Abrams and his online help forum BleepingComputer.com, which have been following and warning about this scourge for several months.
Microsoft warned today that attackers are targeting a previously unknown security vulnerability in some versions of Microsoft Office and Windows. The company also has shipped an interim “Fix-It” tool to blunt attacks on the flaw until it has time to develop and release a more comprehensive patch.
Over the past several weeks, a handful of frantic Microsoft Windows users have written in to ask what they might do to recover from PC infections from “CryptoLocker,” the generic name for an increasingly prevalent and nasty strain of malicious software that encrypts your files until you pay a ransom.

An active phishing campaign targeting account holders at popular Bitcoin exchange MtGox.com has hijacked the top search results at Bing and Yahoo.com, redirecting unwary clickers to mtpox.com, a look-alike domain and Web site that was registered on June 12, 2013, less than 24 hours ago.
One of the most-viewed stories on this site is a blog post+graphic that I put together last year to illustrate the ways that bad guys can monetize hacked computers. But just as folks who don’t bank online or store sensitive data on their PCs often have trouble understanding why someone would want to hack into their systems, many people do not fully realize how much they have invested in their email accounts until those accounts are in the hands of cyber thieves.
