Cobalt Strike Attacks

Posted on November 20, 2020 by John Limb

In the past few weeks, we have seen a significant increase in malicious attacks by bad actors using Cobalt Strike. Cobalt Strike is a legitimate tool used to give penetration testers access to many different attack capabilities. The issue lies when this toolkit gets into the wrong hands. Predominantly we have been seeing Cobalt Strike deploy an agent named “Beacon” for post-exploitation. Deploying this successfully can lead to a Ryuk Ransomware attack.

This week, BraintraceLABS is reporting Cobalt Strike as the most seen malware. Cobalt Strike enters the network in various ways, including via malware like BazarLoader. Malware can be installed with different tricks. The most common way is when the victim is tricked into clicking on a phishing campaign and downloads a file, which can be Word or Excel file. Then the user is tricked into enabling a macro. Once the macro is enabled, the malware will get into the network.

According to Microsoft, Cobalt Strike is being deployed through online ads claiming to be a Microsoft Teams update. The bad actor tricks the victim into clicking on a fake online ad. These advertisements will send the victim to an online domain under the control of the bad actor. When the victim clicks on the link, a download will begin. Instead of receiving the update, the user will download the payload, which can contain Cobalt Strike.

Dragonfly Encrypted Payload Analytics (EPA) prediction model identifies Cobalt Strike Beacon communications.

Braintrace’s Dragonfly is reporting the below C2 indicators of compromise for Cobalt Strike.

Every website domain has hundreds, if not thousands, of permutations.  Most of these permutated domains are completely harmless, involving a simply typographical variation on the original domain name. However, every now and again a fraudster will create a domain based on one of these permutations with bad intentions, hoping to compromise the security of the original domain.  It’s important to understand and take reasonable steps to mitigate this risk, so you can better protect your vital business domains.

Hitting the Sweet Spot for Law Firm Management with Zola Suite 

Posted on December 5, 2019 by Joseph Lamport

In the first part of this series, I wrote about how the platform business model is one of the defining features of our current state of technological and economic development, evident in such business success stories as Uber and Airbnb.  A platform business is one that creates value by facilitating exchanges, of either information, good or services, among otherwise independent groups and individuals via the platform it creates.  I also explained how the platform business model is of growing importance in the legal market, not so much for connecting lawyers to clients but as a means of more effectively connecting the lawyers within a firm and thereby enabling a much more efficient and far more integrated work-flow.

In this second part of the series I’m going to take a closer look at Zola Suite, part of the new generation of cloud-based law practice platforms now available on the market.   Zola Suite formally launched in 2015, after a few years in development, but in fairly short order it has emerged as a market leading solution for mid-sized and larger law firms. This positions Zola in notable contrast to its better-known cloud-based provider, Clio, which has attracted a large number of solos and small firm clients to its platform.

The Law Practice Platform 

Posted on November 12, 2019 by Joseph Lamport

In the past, law firms were held together primarily by their partnership agreements, which laid out the rules for how firm-wide decisions got made and how the spoils of collective labor would be divvied up.  Law firms of the future – whether they are organized as partnerships, LLCs or some other alternative business structure – will most certainly be far more dependent on whatever practice platform they choose to adopt.  It will be the practice platform, much more than the partnership agreement, that provides the insight, controls and coherence that holds the firm together.

Incident Response: What Every Law Firm Needs to Know 

Posted on October 17, 2019 by Katherine Riley, CISA, CISM

One recent study estimated that a cyber-attack occurs every 39 seconds, which underscores the need of every business in America to be prepared for the possibility that their network security will eventually be tested if not breached.  For law firms, the risk is even more severe.  As of 2017, around 20% of all U.S. based law firms had been hacked.  By early 2019, that percentage had risen to an alarming 25%. 

And yet severe as the risk of security breach is, fewer than half of all law firms in the US have an adequate incident response plan in place, and less than a third of those firms with plans have undertaken any testing to ensure their preparedness in case of an attack.  The lack of planning and testing only increases the dangers law firms face.

Law Firms & Ecosystems 

Posted on September 9, 2019 by Anders Spile

For decades, law firms have upheld strong boundaries between the firm and the society in which they operate. The law firm maintains itself as a sturdy fortress, within which hierarchy, culture and tradition go unchallenged. The career path remains clear; associates and junior lawyers execute repetitive work in an attempt to get to the promised land of the equity partner with the result being that billable hours are silently killing all innovative efforts happening lawyer-to-lawyer.

Not in my lifetime

Jordan Furlong has some interesting and sober insights into the legal sector in this pandemic. I'm following almost to the end where he writes, "While I dislike its colonialist connotations, I do feel like the appropriate metaphor right now, for those of us able to lead change in the legal sector, is to 'burn our ships.'" That's not going to work. One, maybe two ships might be set ablaze and will market the heck out of their scorch marks. One might actually burn to the waterline. But for such an overhaul to truly be successful, all the boats in the harbor must be set afire, including the clients. I don't see that happening in my lifetime.

Talk less. Succeed more.

It only takes 4 seconds for silence to feel awkward.; 3) You have power or position; 4) Insecurity; 5) To convince people you're right."
