Threat Source newsletter (Oct. 27, 2022): I thought we were already aware of supply chain attacks?

Supply chain attacks were all the rage in 2020 after SolarWinds, but we seem to have forgotten how important they are.

Welcome to this week’s edition of the Threat Source newsletter.

There are plenty of jokes about whether we’re “aware” of cybersecurity during National Cybersecurity Awareness Month. But now I’m wondering if people are aware of supply chain attacks.

I thought we hit the pinnacle of supply chain attacks in 2020 with the SolarWinds attack, when these types of attacks dominated headlines and defenders started shouting from the mountaintops about how important it is to be ready for supply chain attacks.

And then Kaseya came along a few months later when attackers found a different way to deploy malicious updates that were disguised as legitimate patches.

And still today, we’re warning about the dangers of how prevalent supply chain attacks are and how everyone needs to be ready for this attacker technique. This leaves me wondering if Kaseya and SolarWinds weren’t the breaking point — what is?

It seems like no matter how many times we see major ransomware attacks, even coming to the point of making it impossible for people to get gas, attackers are back again with another ransomware attack a few weeks later.

We still have several hurdles to overcome to fix the supply chain attack problem, as Jaeson Schultz from our Outreach team outlined in this recent post. But it’s clear that these attacks aren’t going anywhere, and neither are defenders’ warnings.

As I wrote at the start of October, it can be easy to poke fun at Cybersecurity Awareness Month because it’s impossible to define what it even means to be “aware” of cybersecurity. Clearly, there’s still awareness to spread, though, and we keep needing to spread it in regard to supply chain attacks, ransomware and pretty much every other type of cyber attack.

The one big thing

For the first time since collecting such data, Cisco Talos Incident Response saw an equal number of ransomware and pre-ransomware engagements, making up nearly 40 percent of threats in the third quarter of 2022. It can be difficult to determine what constitutes a pre-ransomware attack if ransomware never executes and encryption does not take place. However, Talos IR assesses that the combination of Cobalt Strike and credential-harvesting tools like Mimikatz, paired with enumeration and discovery techniques, indicates a high likelihood that ransomware is the final objective.

Why do I care?

This data represents what Talos IR is actively seeing in the wild over the past few months and is likely representative of the broader threat landscape.

So now what?

A lack of MFA remains one of the biggest impediments to enterprise security. Nearly 18 percent of engagements either had no MFA or only had it enabled on a handful of accounts and critical services. Talos IR frequently observes ransomware and phishing incidents that could have been prevented if MFA had been properly enabled on critical services, such as endpoint detection and response (EDR) solutions. Talos IR recommends disabling VPN access for all accounts that are not using two-factor authentication.

Top security headlines of the week

The Biden administration is preparing to release updated guidelines and warnings around election security with a few days left before the midterm elections. A bulletin reportedly being drafted includes information on threats from Russia, China and other state-sponsored actors. Election workers and local officials are also having to deal with physical threats to polling workers and locations, all while the number of volunteers is dwindling. Earlier this month, the U.S. Cybersecurity and Infrastructure Security Agency released a PSA stating that malicious cyber activity is “unlikely to disrupt or prevent voting.” (Politico, Axios, Voice of America)

Apple released security updates for its iOS and iPadOS operating systems this week, including fixes for a vulnerability that “may have been actively exploited.” There are 20 vulnerabilities fixed in these updates in all. CVE-2022-42827 is the most notable vulnerability, which could allow an attacker to execute code with Kernel privileges via an attacker-controlled app. This is the third Kernel-related out-of-bounds memory vulnerability that Apple has patched in each of its previous security updates: CVE-2022-32894 and CVE-2022-32917. CVE-2022-32917 was known to be used in attacks in the wild. (Forbes, The Hacker News)

Two vulnerabilities in Microsoft’s Mark of the Web (MoTW) security feature could allow an attacker to send JavaScript files that could bypass security blocks in place. Attackers are reportedly actively exploiting both issues, though Microsoft has yet to issue any formal fixes for the vulnerabilities, and there are no workarounds available. Mark of the Web protects users against files from untrusted sources, but the two vulnerabilities could allow the attackers to construct the files in a way that they are not appropriately marked by Windows. Attackers commonly use .js files as attachments or downloads that can run outside a web browser. (Dark Reading, Bleeping Computer)

Threat Source newsletter (Sept. 15, 2022) — Why there is no one-stop-shop solution for protecting passwords

By Jon Munshaw.  Welcome to this week’s edition of the Threat Source newsletter.  Public schools in the United States already rely on our teachers for so much — they have to be educators, occasional parental figures, nurses, safety officers, law enforcement and much more. Slowly, they’re having to add “IT admin” to their list of roles.  Educational institutions have increasingly become a target for ransomware attacks, an issue already highlighted this year by a major cyber attack on the combined Los Angeles school district in California that schools are still recovering from.  Teachers there reported that during the week of the attack, they couldn’t enter attendance, lost lesson plans and presentations, and had to scrap homework plans. Technology has become ever-present in classrooms, so any minimal disruption in a school’s network or software can throw pretty much everything off.  The last thing teachers need to worry about now is defending against a well-funded threat act...

Threat Source newsletter (Aug. 25, 2022) — Why aren't Lockdown modes the default setting on phones?

By Jon Munshaw.  Welcome to this week’s edition of the Threat Source newsletter.  Russia’s invasion of Ukraine was once the most talked about story in the world. Six months into the conflict, modern attention spans have moved on to other news stories. But Ukraine Independence Day yesterday should serve as a reminder to everyone that the threats to Ukraine have not gone anywhere.  The country still faces a physical conflict with Russia every day that seemingly has no easy end, and the barrage of cyber attacks is suspected to continue.   As discussed in our livestream yesterday, Talos continues to see evolving cybersecurity threats in the region, including the most recent GoMet backdoor. And as Joe Marshall highlighted in his blog post last week, Ukraine’s agriculture industry — which is vital to the global food supply chain — remains vulnerable to kinetic and virtual attacks. Because there’s been no one major cyber attack against Ukraine since Russia’s invasion began, the larg...
