A story published here on July 12 about a new sextortion-based phishing scheme that invokes a real password used by each recipient has become the most-read piece on KrebsOnSecurity since this site launched in 2009. And with good reason — sex sells (the second most-read piece here was my 2015 scoop about the Ashley Madison hack).
But beneath the lurid allure of both stories lies a more unsettling reality: It has never been easier for scam artists to launch convincing, targeted phishing and extortion scams that are automated on a global scale. And given the sheer volume of hacked and stolen personal data now available online, it seems almost certain we will soon witness many variations on these phishing campaigns that leverage customized data elements to enhance their effectiveness.
For the second time in a week, Adobe Systems Inc. says it plans fix a zero-day vulnerability in its Flash Player software that came to light after hackers broke into and posted online hundreds of gigabytes of data from Hacking Team, a controversial Italian company that’s long been accused of helping repressive regimes spy on dissident groups.
I’ve spent the better part of the last month running a little experiment to see how much I would miss Adobe’s buggy and insecure Flash Player software if I removed it from my systems altogether. Turns out, not so much.
For the second time this month, Adobe has issued a security update for its Flash Player software. New versions are available for Windows, Mac and Linux versions of Flash. The patch provides additional protection on a vulnerability that Adobe fixed earlier this year for which attackers appear to have devised unique and active exploits.
Not long ago, miscreants who wanted to buy an exploit kit — automated software that helps booby-trap hacked sites to deploy malicious code — had to be fairly well-connected, or at least have access to semi-private underground forums. These days, some exploit kit makers are brazenly advertising and offering their services out in the open, marketing their wares as browser vulnerability “stress-test platforms.”
Microsoft and Symantec said Wednesday that have teamed up to seize control over the “Bamital” botnet, a multi-million dollar crime machine that used malicious software to hijack search results. The two companies are now using that control to alert hundreds of thousands of users whose PCs remain infected with the malware.
If your computer is running Java and you have not updated to the latest version, you may be asking for trouble: A powerful exploit that takes advantage of a newly-disclosed security hole in Java has been rolled into automated exploit kits and is rapidly increasing the success rates of these tools in attacking vulnerable Internet users.
Anyone who’s run a Web site is probably familiar with the term “malvertising,” which occurs when crooks hide exploits and malware inside of legitimate-looking ads that are submitted to major online advertising networks. But there’s a relatively new form of malware-based advertising that’s gaining ground — I’m calling it “crimevertising” for lack of a better term — that involves running otherwise harmless ads for illicit services inside of commercial crimeware kits.
At its most basic, crimevertising has been around for many years, in the form of banner ads on underground forums that hawk everything from hacking services to banking Trojans and crooked cashout services. More recently, malware authors have started offering the ability to place paid ads in the administrative panesl that customers use to control their botnets. Such placements allow miscreants an unprecedented opportunity to keep their brand name in front of the eyeballs of their target audience, and for hours on end.
An exploit for a recently disclosed Java vulnerability that was previously only available for purchase in the criminal underground has now been rolled into the open source Metasploit exploit framework. Metasploit researchers say the Java attack tool has been tested… Read More »
In October, I showed why Java vulnerabilities continue to be the top moneymaker for purveyors of “exploit kits,” commercial crimeware designed to be stitched into hacked or malicious sites and exploit a variety of Web-browser vulnerabilities. Today, I’ll highlight a few more recent examples of this with brand new exploit kits on the market, and explain why even fully-patched Java installations are fast becoming major enablers of browser-based malware attacks.
