Why Codefinger represents a new stage in the evolution of ransomware

Forget typical ransomware! Codefinger hijacked cloud keys directly, exposing backup flaws and shared responsibility risks. Time to rethink defence. If you didn't pay much attention to news of the recent Codefinger ransomware attack, it's possibly because ransomware has become so prevalent that major incidents no longer feel notable. But Codefinger is not just another ransomware breach to add to the list of incidents where businesses lost sensitive data to attackers. In key respects, Codefinger represents a substantially new type of ransomware attack.

The Change Healthcare hack wasn't just a breach-it was a wake-up call

"The US healthcare system is broken" is not an uncommon phrase. With no universal healthcare coverage, administrative inefficiencies, and an under-resourced primary care system, it's so bad that falling ill could very well bankrupt a citizen.

Effective Deception for Zero Day Attacks: Strategies for Cyber Defense

Deception for Zero day attacks has become a crucial strategy as these devastating exploits continue to surge rapidly. These attacks pose extreme danger because they target vulnerabilities unknown to software vendors or the public, which leaves systems defenseless without immediate patches. Attackers can exploit these vulnerabilities undetected for extended periods – from days to years. This creates a huge window for attacks before vendors can patch the problems.

One SQL Injection Could Bring Down Your App. Here's How to Prevent It

SQL Injection represents the most common web application vulnerability, and justifiably so: it is the most dangerous. Attackers can inject SQL code into victims' sites and access databases, potentially allowing unauthorized access and data compromise or, worst case, full-blown compromise of the site. Shielding one's website against SQL injections would mean having to understand how SQL injections work and implement preventive measures against them.

Attackers Abuse TikTok and Instagram APIs

It must be the season for API security incidents. Hot on the heels of a developer leaking an API key for private Tesla and SpaceX LLMs, researchers have now discovered a set of tools for validating account information via API abuse, leveraging undocumented TikTok and Instagram APIs. The tools, and assumed exploitation, involve malicious Python packages - checker-SaGaF, stein lurks, and inner core - uploaded to PyPI.

M&S and Co-op Cyber Attacks: A Wake-Up Call for Every Business

In recent weeks, UK retail giants Marks & Spencer and the Co-op have faced serious cyber attacks that disrupted operations and compromised customer data.

Key Takeaways from the IBM X-Force 2025 Threat Intelligence Index

Attackers have made a decisive switch toward stealthy, identity-centric attacks. Forget breaking in – modern cybercriminals simply log in. And that should be a concern. According to the IBM X-Force 2025 Threat Intelligence Index, nearly one-third of intrusions in 2024 were initiated not through sophisticated attacks, but through valid account exploitation.

Storm-0558 and the Dangers of Cross-Tenant Token Forgery

Modern cloud ecosystems often place a single identity provider in charge of handling logins and tokens for a wide range of customers. This approach certainly streamlines single sign-on (SSO) for end users, but it also places enormous trust in a single set of signing keys. If those private keys are compromised, attackers can create tokens that appear valid to any service that relies on them.

DDoS Protection: Insurance Policy or Proactive Defense?

Historically, smaller organizations or those outside highly targeted industries for distributed-denial-of-service (DDoS) attacks have thought of DDoS protection more akin to an insurance policy than proactive cyber defense, i.e. we’ll put some reactive processes in place “in case we get hit,” but not much more.

What Is Scattered Spider? Inside the Rise of Identity-Based Attacks

If you’ve been following major cybersecurity incidents over the past couple of years, chances are you’ve come across the name Scattered Spider. From massive casino breaches to healthcare system outages, this threat actor has become a name that CISOs don’t take lightly. But what is Scattered Spider, really? And why is this group of cybercriminals getting so much attention? Scattered Spider is a financially motivated group that came into focus around 2022.

The Rise of Identity-Based Attacks and How Deception Can Help

Identity-based attacks have become the predominant vector for sophisticated threat actors targeting enterprise networks, particularly those using Microsoft Active Directory. Active Directory (AD), which serves as the authentication and authorization framework in over 90% of organizations, represents a critical attack surface that, when compromised, provides adversaries with extensive capabilities for lateral movement, privilege escalation, and data exfiltration.

Improving Cyber and Mental Resilience with Threat Information Sharing

In a world where data provides companies with a competitive advantage, sharing it amongst other businesses, especially in the same industry, may seem counterproductive. However, in cybersecurity, where every company is a potential target for threat actors and organizations are increasingly interconnected through supply chains, sharing information can significantly enhance a company's security posture and overall resilience.

Guarding Against Dependency Attacks: Essential Strategies for Modern Application Development

Dependency management is one of the biggest challenges in modern software development. Large projects often rely on dozens or even hundreds of libraries. Each one can introduce new vulnerabilities or even malicious code. Attackers sometimes upload fake packages to popular open-source repositories, hoping that build systems will download these packages automatically. This problem is made worse by transitive dependencies, where a single library might include several other libraries under the hood.

The group also poses as IT workers to target employees.

Risks of Using Public Wi-Fi for Crypto Transactions

As cryptocurrency adoption continues to rise, the ease of managing assets through mobile wallets and trading platforms has brought a new layer of convenience. However, this accessibility can also lead to overlooked security risks, especially when users rely on public Wi-Fi networks for transactions. Airports, coffee shops, hotels, and public transportation hubs may offer free internet access, but these networks present significant vulnerabilities that can expose sensitive information.

A Subtle Form of Siege: DDoS Smokescreens as a Cover for Quiet Data Breaches

DDoS attacks have long been dismissed as blunt instruments, favored by script kiddies and hacktivists for their ability to overwhelm and disrupt. But in today's fragmented, hybrid-cloud environments, they've evolved into something far more cunning: a smokescreen. What looks like digital vandalism may actually be a coordinated diversion, engineered to distract defenders from deeper breaches in progress.

You Are Still Vulnerable to Password Attacks When Using Passkeys

Just because you’re using a passkey doesn’t mean your password is gone. Microsoft is going passwordless in a new big push. As part of that new initiative, they are strongly pushing FIDO passkeys. I am a big fan of FIDO passkeys and FIDO in general. FIDO authentication offerings, including passkeys, are phishing-resistant, which makes them a HUGE improvement over passwords and most other multi-factor authentication products.

Human-Directed Threats: The New Frontline in Cybersecurity

A constantly shifting threat landscape has given rise to a new cyberattack vector, driven by two powerful forces: the rapid migration of data to the cloud and the fundamental change in how employees access and interact with that data. Today’s workforce expects the freedom to work and access information from any device—especially mobile devices, which have become integral to their professional and personal lives.

What Is a Supply Chain Attack?

A supply chain attack does not start with your firewall. It starts with someone else’s. Instead of targeting your company directly, a cyber attacker looks for weak spots in your organization’s supply chain. That could be a trusted third-party vendor, a widely used software supplier, or even an outdated package from an open-source code repository. Once they find an opening, they exploit security vulnerabilities to gain access to your systems without ever going through the front door.

Firmware's Blind Spot:7Ways HardwareComponentShortages Open NewAttack Paths

When a nextgeneration firewall ships with a Secure Boot bypass baked into its firmware, it is easy to assume the culprit lies in sloppy software. Yet the root cause often hides deeper: a lastminute swap of an outofstock component that the firmware team never fully audited. In 2023 alone, Resilinc's EventWatch AI recorded 7 422 hightech supplychain disruption alerts-over half severe enough to trigger "WarRoom" responses (Resilinc, 2023). These shortages force engineers to scour greymarket brokers, accept pincompatible "dropins," or resurrect endoflife (EoL) parts just to keep production lines moving.

Pre-emptive Account Takeover Detection: 5 Steps to Expose Scammers Early

Modern security leaders know that account takeover detection (ATO) isn’t just about spotting a bad login. ATO attacks are part of a broader scam lifecycle – starting with phishing or impersonation, escalating into credential harvesting, and ending with unauthorized access. To stop ATOs effectively, security teams need visibility into this full progression, not just the login attempt. That’s why a true ATO prevention strategy starts long before a password is entered.

Weeding Out Cyber Threats: How to Detect and Stop Common Attacks

When necessary, you water it, monitor it, and weed out what doesn’t belong before it spreads. The same principle applies to cybersecurity. In today’s digital landscape, cyber threats evolve rapidly. From phishing and privilege escalation to rogue access and lateral movement, attacks often take root well before they’re discovered. That’s why detection and response are no longer optional ‒ essential for resilience.
