Apple's emergency patch, AI-generated art and more security headlines from the past week.

Thursday, June 29, 2023 14:06

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

AI-generated art is causing drama across the internet over the past few months, from Marvel TV show opening credits scenes to predatory YouTubers who claim YOU can make millions by having AI tools create children’s books for you.

There are all sorts of ethical and legal implications that AI-generated art has that I don’t have the space here to cover, but I did think it was worth noting that these tools are already being used in cyber attacks and online scams.

These tools can create extremely convincing deepfake art that could lead to the spread of misinformation or disinformation, especially concerning major news events and political figures. I’ve written about this in the newsletter before.

There are also dozens of apps that promise to create convincing AI art or portraits of people serving another malicious purpose. As McAfee pointed out in this blog post, some Android apps offered to “zhuzh up” users’ profile pictures with AI filters but were actually trojanized apps with hidden information stealers. And at the end of the day, they were all using the same basic filters. Many of these apps could also be stealing and re-using the pictures users submitted to these apps (remember the saga of the app that showed what it would be like when you got old?).

I have more to get to this week, so I’m not going to go much deeper into the subject, but as always, be vigilant of apps’ privacy policies and do a quick background check on their creators before downloading something hoping to create a Skrull version of yourself.

I’m also excited to show off this new video featuring a behind-the-scenes interview with Talos.

This video from Cisco Secure shines a spotlight on the evolution and future of ransomware. Watch it below or over on Cisco.com here to find out how our threat hunters identify new and evolving threats in the wild, and how their research and intelligence help organizations build strong defenses.

**The one big thing**

Apple released an emergency patch last week for all its operating systems for two zero-click vulnerabilities that could allow an attacker to completely take over a targeted device. The two vulnerabilities, identified as CVE-2023-32434 and CVE-2023-32435, were used to reportedly compromise phones in Russia. The issues were part of the so-called Triangulation spyware discovered on iPhones of employees of Kaspersky, a Russia-based cybersecurity company, but the malware was removed from phones after a device reboot.

**Why do I care?**

The chances of being targeted by the Triangulation spyware is slim-to-none based on what the security community knows to this point, but either way, the existence of a zero-day vulnerability in iOS is always big news. Apple encouraged users to upgrade to iOS 16.5.1 and iPadOS 16.5.1 for users of those devices. The company also said that CVE-2023-32434 "may have been actively exploited against versions of iOS released before iOS 15.7."

**So now what?**

All Apple users should update these affected products as soon as possible. The U.S. Cybersecurity and Infrastructure Security Agency also released an advisory telling “users and administrators to review \[Apple’s\] advisories and apply the necessary updates.”

**Top security headlines of the week**

The self-identifying hacktivist group “Anonymous Sudan” is **more active than initially thought.** While researchers are still unsure as to the group’s connections to any nation-states, the group says it’s advocating on behalf of Sudan. It first came onto the scene earlier this month, taking credit for a distributed denial-of-service attack against Microsoft that affected Outlook. Now, researchers are saying their activities actually started prior to that with attacks targeting Israel, Sweden and other nations earlier this year. Microsoft confirmed last week that a Layer 7 DDoS attack was responsible for outages affecting Azure, Outlook and OneDrive, saying that, “these attacks likely rely on access to multiple virtual private servers (VPS) in conjunction with rented cloud infrastructure, open proxies, and DDoS tools” and that there is “no evidence that customer data has been accessed or compromised." (Bloomberg, Bleeping Computer)

**The list of companies affected by the MOVEit breach continues to grow.** Clop, the threat actor behind the attacks, added Schneider Electric and Siemens Energy — two major electric corporations — to its leak site this week. The University of California Los Angeles (UCLA) also confirmed it discovered on June 1 that it was the target of the campaign, though it quickly engaged the college’s incident response team and patched the issue. Since the attack went public, Clop’s leak site mainly called out seven U.S. state and local governments, including the nation’s largest public-employee pension fund — the California Public Employees’ Retirement System. And the New York City public school system was also affected, with more than 45,000 students having their personal data stolen, including sensitive information like Social Security numbers. (The Record by Recorded Future, CyberScoop)

**The FBI seized the domain belonging to the infamous hacking site BreachForums,** three months after arresting its creator. Users of BreachForums were known for sharing and selling stolen personal data from a variety of websites and companies. BreachForums was quiet for several weeks after the admin, known as “Pompompurin,” was arrested. However, the site’s newest admin decided to launch the site on new servers earlier this month. In addition to the usual display of the law enforcement agencies’ logos who were involved in the takedown, BreachForums’ homepage now also displays an image of the avatar Pompompurin used in handcuffs.

New video provides a behind-the-scenes look at Talos ransomware hunters

Organizations should consider their security practices the same way people think about their well-being. Focus on staying healthy instead of finding a new pill for every security symptom you see.

Since the early 1990s, we've watched the internet evolve from dial-up connections to high-speed, cloud-based computing. Organizations have navigated a shifting maze of technology while defending against cyberattacks. Sadly, after three decades in cybersecurity, I see organizations wrestling with the same problems in 2023 that they grappled with in 1995 when they first plugged into the internet.

Attacks on users through email, attacks on availability through denial-of-service campaigns, and exploits of systems through vulnerable applications are longstanding strategies that remain fruitful for threat actors.

Even today, with increased awareness and public reporting of data breaches, business leaders and developers aren't taught to balance new technologies with the required security. Organizations still focus on functionality and time to market, not on ensuring secure, predictable behavior. This creates a weakened infrastructure that attackers continue to prey on successfully and daily.

So, why do cybersecurity losses continue growing despite a projected $188.3 billion global annual spending on information security and risk management products and services?

**We're Treating Symptoms, Not Causes**

Vendor messaging over the decades has trained the marketplace to believe the solution to cybersecurity challenges is technology. More and more technology. The same proposition leads people to think they can lose weight with a pill — not eating better or exercising more, but a quick and easy solution so that they can pay to make the problem disappear.

The growth of security budgets shows this line of thinking is pervasive and leads to a vicious cycle of trying to outspend risk. In truth, while much of the technology is valuable, cybersecurity issues arise in the gaps.

Like prescriptions that are stopped mid-course or bandages over broken bones, technology adopted without a plan can create misplaced confidence in an incomplete system. Many organizations focus on shiny, new attacks at the expense of solid foundational protection, and this misprioritization has continued a culture of victimization and never-ending vulnerabilities.

The rising cost and destructive power of cyberattacks aren't new; they're collateral damage from years of neglecting basic security policies and best practices. Increased security investment is spent on niche protection technologies promoted by analysts, vendors, press coverage, and practitioner curiosity.

The constant change in tooling and focus also leads to burnout and job dissatisfaction among experienced leaders, exacerbating the cybersecurity skills shortage. To address ongoing vulnerability and increasing stress, we need to think about cybersecurity differently, recognizing that successful businesses rely on a healthy security posture.

**Cybersecurity's Preventive Medicine**

Organizations should consider their security practices the same way people think about their well-being. Focus on staying healthy instead of finding a new pill for every security symptom you see. The same principles you hear from the doctor apply to cybersecurity resilience: Diet, exercise, and regular checkups.

Security's basic food groups are prevention, detection, response, and remediation. Address each appropriately based on the specifics of your organizational need. Too little prevention and your detection, response, and remediation will be swamped. Too little response and security events will drag on. Your security program should consume only what it needs and what your team can digest and use. Any more than this, and you'll be carrying extra weight in your budget.

Cybersecurity conditioning means regularly conducting awareness training, tabletop exercises, practitioner certifications, asset inventory verifications, and penetration tests. Keep the team up to date on roles and responsibilities. Your response will be faster and more targeted, and your organization less disturbed, if you take the time to work out that security muscle regularly.

No one likes going for a yearly physical, but it's a great way to learn if you're as healthy as you think. Find time to run through your security program to make sure it's still balanced. Have your team double-check critical controls and compliance with relevant standards or best practices. Get a second opinion once in a while. Find a third party that doesn't have the context of your business and ask what they see. Good cybersecurity health means looking for even small indications something may have been missed. It doesn't take long for that blind spot to put your whole effort at risk.

**If You Do Get Sick…**

Maintaining a resilient, trustworthy security system is complicated by new capabilities and a diverse threat landscape. By some estimates, more than 250,000 new pieces of malware are detected daily. We need to diagnose and treat new problems like the healthcare industry addresses constantly changing epidemiological challenges.

The healthcare system keeps up with new and mutating diseases because specialists focus on a single condition, determining the best means to identify and diagnose it. Another group focuses on treatment to quell the problem early. Others develop the specialized equipment that powers diagnosis and treatment, while hospitals and the entire healthcare ecosystem support patients.

If we understand our organizations and the threats we're likely to face, we can begin to live the healthy, budgetable, and predictable corporate cybersecurity life we've sought for decades. By taking cyber health more seriously, we can cure the fundamental problems that have plagued the industry for the past 30 years and stop merely treating the symptoms and attacks.
