How do companies regardless of size and industry prepare for ransomware attacks? A recent study revealed that businesses are considering saving up Bitcoins, just in case they get hit by these threats and can recover their confidential files in a short span of time. While we don’t recommend succumbing to the ransom payment as it doesn’t guarantee that you’ll get your files back plus you’ll be prone to more ransomware attacks, we can’t also blame these large organizations and businesses for doing so.

In the first four months of 2016, we have discovered new families and variants of ransomware, seen their vicious new routines, and witnessed threat actors behind these operations upping the ransomware game to new heights. All these developments further establish crypto-ransomware as a lucrative cybercriminal enterprise. As we predicted, this year is indeed shaping up to be the year of online extortion,  and while the security industry may be doing an admirable job of keeping up with the latest new tactic and providing solutions, the not-so informed public and organizations may very well be on the receiving end of a crippling malware that can destroy personal and corporate files, as well as lead to huge financial losses.

A Lesson on Patching: The Rise of SAMSAM Crypto-Ransomware

The critical role of patch management comes into play when vulnerabilities are used by attackers as entry points to infiltrate their target systems and networks or when security flaws are abused to spread any threats.  The case of the infamous SAMSAM crypto-ransomware supports this. The said threat deviated from other crypto-ransomware families. Instead of arriving via malicious URLs or spam emails, it leverages security flaws in unpatched servers.  Last March 2016, SAMSAM hit the Maryland hospital by encrypting all its files, including those found in the network.  From the healthcare industry, SAMSAM moves to target the education sector. In a  recent attack,  a significant number of servers and systems were exposed to SAMSAM and other malware via JBoss server vulnerabilities. JBoss is an open source application server that runs on Java. Systems or servers with ‘Destiny’ software were also affected. According to a report by CISCO, this software is typically used by K-12 schools worldwide. Follett has already released a patch to protect users of Destiny software.

Business Process Compromise

  • Attackers are starting to invest in long-term operations that target specific processes enterprises rely on. They scout for vulnerable practices, susceptible systems and operational loopholes that they can leverage or abuse. To learn more, read our Security 101: Business Process Compromise.
