HP Wolf Security - Malware Meal Kits techbuzzireland

HP Ireland issued its quarterly HP Wolf Security Threat Insights Report, showing that thriving cybercriminal marketplaces are offering low-level attackers the tools needed to bypass detection and infect users.

Based on data from millions of endpoints running HP Wolf Security, key findings include:

  • Houdini’s Last Act: A new campaign targeted businesses with fake shipping documents concealing JavaScript malware. Its obscure code allowed the malware to slip past email defences and reach endpoints. The analysed attack delivered Houdini, a 10-year-old malware. This shows that, with the right pre-packaged tools from cybercrime marketplaces, hackers can still use vintage malware effectively by abusing the scripting features built into operating systems.
  • Cybercriminals Deploy “Jekyll and Hyde” Attacks: HP discovered a separate campaign launching two threads when a user opens a malicious scanned invoice designed to trick users. The “Jekyll” thread opens a decoy invoice copied from a legitimate online template, reducing suspicion, while the “Hyde” runs the malware in the background. This attack would be easy for threat actors to carry out, as pre-packaged kits to carry out this type of hacking have been advertised on forums for around €62 / $65 per month.

HP also identified attackers are hazing aspiring cybercriminals by hosting fake malware building kits on code sharing platforms like GitHub. These malicious code repositories trick wannabe threat actors into infecting their own machines. One popular malware kit, XWorm, is advertised on underground markets for as much as €474 / $500, driving resource-strapped cybercriminals to buy fake versions.

By isolating threats that have evaded detection tools on PCs – but still allowing malware to detonate safely – HP Wolf Security has specific insight into the latest techniques used by cybercriminals in the fast-changing cybercrime landscape. To date, HP Wolf Security customers have clicked on over 30 billion email attachments, web pages, and downloaded files with no reported breaches.

The report details how cybercriminals continue to diversify attack methods to bypass security policies and detection tools. Other findings include:

  • Archives were the most popular malware delivery type for the sixth quarter running, used in 36% of cases analysed by HP.
  • Despite being disabled by default, macro-enabled Excel add-in threats (.xlam) rose to the 7th most popular file extension abused by attackers in Q3, up from 46th place in Q2. Q3 also saw malware campaigns abusing PowerPoint add-ins.
  • At least 12% of email threats identified by HP Sure Click bypassed one or more email gateway scanners in both Q3, and Q2.
  • Q3 saw an increase in attacks using exploits in Excel (91%) and Word (68%) formats.
  • There was a 5%-point rise in PDF threats isolated by HP Wolf Security compared to Q2.
  • The top threat vectors in Q3 were email (80%) and downloads from browsers (11%).

Val Gabriel, Managing Director of HP Ireland, comments: “This quarter’s report has found that threat actors can easily and inexpensively purchase pre-packaged, user-friendly malware ‘meal kits’. We have found that these kits infect systems with a single click. So, instead of creating their own tools to breach security systems, low-level cybercriminals can now access kits that use living-off-the-land tactics. These stealthy in-memory attacks are often harder to detect due to security tool exclusions for admin use, like automation.

“While the tools for crafting stealthy attacks are readily available, threat actors still rely on the user clicking in order to infect systems,” continues Val Gabriel. “To neutralise the risk of falling victim to pre-packaged malware kits, businesses should isolate any high-risk activities, like opening email attachments, link clicks, and downloads, as doing so, significantly minimises the potential of a breach by reducing the attack surface.”

HP Wolf Security runs risky tasks in isolated, hardware-enforced virtual machines running on the endpoint to protect users, without impacting their productivity. It also captures detailed traces of attempted infections. HP’s application isolation technology mitigates threats that slip past other security tools and provides unique insights into intrusion techniques and threat actor behaviour.
