Here Are 4 Vulnerabilities Ransomware Attacks Are Exploiting Now

A zero-day exploit exposed in the Hacking Team breach is among the top weapons deployed in recent ransomware attacks, as well as lots of Flash.

Don’t blink, but there’s a common thread in the most recent ransomware attacks: they use four known Adobe Flash Player and Microsoft Silverlight software bugs that have patches available, according to new research published today.

So if you haven’t already patched recently revealed Flash flaws CVE-2015-7645, CVE-2015-8446, CVE-2015-8651, and Microsoft Silverlight’s CVE-2016-0034, you’ll “significantly” minimize your risk of getting hit by the latest in ransomware threats if you apply these updates, according to Recorded Future, which analyzed which vulns were being exploited most in ransomware attacks as of March 16.

Scott Donnelly, a director at Recorded Future, says he launched the study after talking with a friend at a local Blue Cross/Blue Shield location about worries of the potential threat of a ransomware attack. The organization relies on a vendor for its software-patching, so that made Donnelly wonder which vulnerabilities are being used most by popular exploit kits in ransomware attacks.

“There are multiple ways to get hit by ransomware. We looked at some of the recent vulnerabilities with exploits ... for patch prioritization” planning, Donnelly says.

Recorded Future says its analysis suggests that recent highly publicized attacks on hospitals and police departments in North American and Europe were most likely not targeted attacks: instead, the bad guys had cast a wide net and those poorly patched systems landed right in it.

“We’re now at the point where you can get crippled in same way as with targeted attack [as you can] by an untargeted one,” Donnelly says. “A hospital worker using an EMR [electronic medical record]... Googles a patient’s condition and gets ransomware,” for example.

The Angler, Neutrino, Magnitude, RIG, and Nuclear exploit kits spread the Flash CVE 2015-7645 exploit; Angler spreads Flash 2015-8446; Angler and Neutrino spread Flash CVE 2015-8651; and Angler spreads Silverlight CVE-2016-0034, an exploit exposed in the Hacking Team breach.

In addition to patching these four vulns, Recorded Future offers additional recommendations for thwarting ransomware attacks: set Flash to “click to play;” run browser ad-blockers to protect against malvertising-borne attacks; and perform regular backups, especially of shared files, which are often the target of ransomware attacks.

“If you don’t make the decision to keep backups offline when you’re hit, you have a binary decision: either pay the ransom or lose the data,” says Levi Gundert, director of intelligence strategies at Recorded Future.

Meanwhile, ransomware victim counts are likely more widespread than is publicly known. “So many companies don’t publicize that they’ve been hit” by ransomware, Donnelly says.

Down with Flash
InfoSec professionals agree, and its time industry acted.  Flash should be gone.  It should be banned.  It should be expunged.  (For goodness sakes, we have HTML5 now!)  There is no excuse anymore.

(Or, as The Register once put it: Flash apologists are "the antivaxxers of the Internet".)

Re: Down with Flash
I totally agree with your post. I presently have flash since it is required with the kronos timekeeping workforce application. It also requires Java. ; (

"It also requires Java."

Wow.  Double-whammy.  :/

Java has been found to have more vulnerabilities than Flash, actually -- but, on the whole, they lack the severity of Flash vulnerabilities.
