WatchGuard® Technologies, has released the findings of its new Internet Security Report for Q2 2018, which explores the latest security threats affecting small to midsize businesses (SMBs) and distributed enterprises.
This new research from WatchGuard Threat Labs revealed that 50% of government and military employee ‘LinkedIn’ passwords were weak enough to be cracked in less than two days.
This finding, along with the emergence of the Mimikatz credential-stealing malware as a top threat and the popularity of brute force login attacks against web applications, underscores the reality that passwords alone can’t offer sufficient protection, and emphasizes the need for multi-factor authentication (MFA) solutions, in every organization.
“Authentication is the cornerstone of security, and we’re seeing overwhelming evidence of its critical importance in the common trend of password- and credential-focused threats throughout Q2 2018,” explains Corey Nachreiner, chief technology officer at WatchGuard Technologies.
“Whether it’s an evasive credential-stealing malware variant or a brute force login attack, cyber criminals are laser-focused on hacking passwords for easy access to restricted networks and sensitive data.”
“At WatchGuard, these trends are driving new innovative defenses within our product portfolio, including AuthPoint, our Cloud-based multi-factor authentication solution and our IntelligentAV service, which leverages three malware detection engines to prevent malware strains that evade traditional signature-based antivirus products.”
“Every organization should seek out vendor and solution provider partners that offer layered protection against these ever-evolving attack techniques.”

The insights, research and security best practices included in WatchGuard’s quarterly Internet Security Report are designed to help organizations of all sizes understand the current cyber security landscape and better protect themselves, their partners and customers from emerging security threats.
Roughly half of government and military employee passwords are weak.
-
After conducting a thorough analysis of the 2012 LinkedIn data dump to identify trends in user password strength, WatchGuard’s Threat Lab team found that half of all passwords associated with “.mil” and “.gov” email address domains within the database were objectively weak.
-
Of the 355,023 government and military account passwords within the database, 178,580 were cracked in under two days.
-
The most common passwords used by these accounts included “123456,” “password,” “linkedin,” “sunshine,” and “111111.”
-
Conversely, the team found that just over 50% of civilian passwords were weak.
-
These findings further illustrate the need for stronger passwords for everyone, and a higher standard for security among public service employees that handle potentially sensitive information.
-
In addition to better password training and processes, every organization should deploy multi-factor authentication solutions to reduce the risk of a data breach.
Key Takeaways from the Q2 2018 Report Include:
Mimikatz was the most prevalent malware variant in Q2.
-
Representing 27.2% of the top 10 malware variants listed last quarter, Mimikatz is a well-known password and credential stealer that has been popular in past quarters, but has never been the top strain.
-
This surge in Mimikatz’s dominance suggests that authentication attacks and credential theft are still major priorities for cyber criminals – another indicator that passwords alone are inadequate as a security control, and should be fortified with MFA services that make hackers’ lives harder by requiring additional authentication factors in order to successfully login and access the network.
More than 75% of malware attacks are delivered over the web.
-
A total of 76% of threats from Q2 were web-based, suggested that organizations need an HTTP and HTTPS inspection mechanism to prevent the vast majority of attacks.
-
Ranked as the fourth most prevalent web attack in particular, “WEB Brute Force Login -1.1021” enables attackers to execute a massive deluge of login attempts against web applications, leveraging an endless series of random combinations to crack user passwords in a short period of time.
-
This attack in particular is another example of cyber criminals’ heightened focus on credential theft, and shows the importance of not only password security and complexity, but the need for MFA solutions as a more effective preventative measure.

Cryptocurrency miners earn spot as a top malware variant.
- As anticipated, malicious cryptominers are continuing to grow in popularity as a hacking tactic, making their way into WatchGuard’s top 10 malware list for the first time in Q2.
- Last quarter, WatchGuard uncovered its first named cryptominer, Cryptominer.AY, which matches a JavaScript cryptominer called “Coinhive” and uses its victims’ computer resources to mine the popular privacy-focused cryptocurrency, Monero (XRM).
- The data shows that victims in the United States were the top geographical target for this cryptominer, receiving approximately 75% of the total volume of attacks.
Cyber criminals continue to rely on malicious Office documents.
- Threat actors continue to booby-trap Office documents, exploiting old vulnerabilities in the popular Microsoft product to fool unsuspecting victims.
- Interestingly, three new Office malware exploits made WatchGuard’s top 10 list, and 75% of attacks from these attacks targeted EMEA victims, with a heavy focus on users in Germany specifically.
