Colonial Pipeline was shut down for six days after finding itself at the center of a cybersecurity threat. During the May 2021 incident, States declared emergencies, gas prices soared to a six-year high, fuel shortages hit Southeast America, and panic buying almost threatened national fuel security. As per The New York Times report, the attack was traced to DarkSide, a Russian-speaking ransomware group that used a stolen VPN password to breach Colonial’s systems. With critical operations encrypted, the company paid nearly $5 million to regain access, only to face lawsuits and lasting damage to its reputation.
“Every fragility was exposed, and we learned a lot about what could go wrong. Unfortunately, so did our adversaries.”
- Dmitri Alperovitch, Chairman of Silverado Policy Accelerator
The Colonial Pipeline attack wasn’t just a one-off incident but a sign of things to come. As we move into 2025, AI-driven, multi-layered cyberattacks will cost enterprises as much as $10.5 trillion and put a serious strain on already burned IT teams.
However, with the right capabilities and a proactive strategy, organizations can strengthen their infrastructure against evolving cyber threats. The key lies in understanding the risk landscape and anticipating potential vulnerabilities. Here, we outline five critical cyber threats that could impact your operations - and how to mitigate them effectively.
Phishing
Phishing is a cybersecurity attack where criminals trick people into revealing sensitive information by pretending to be legitimate organizations or individuals. Attackers often impersonate trusted entities like banks, social media platforms, or colleagues to create a false sense of urgency. More panic in the audience will pressure quick responses, and hackers will be able to run credential phishing, social engineering attacks, and password harvesting.
As of now, phishing continues to be the most commonly reported engineering attack and shows no signs of slowing down. GPT is now generating phishing emails and SMSes that look and sound incredibly real and are hard to distinguish from legitimate messages. A Black Hat USA experiment by Singapore’s Government Technology Agency found that people actually fell for AI-generated phishing emails more often than human-written ones.
To fight back, chief information security officers (CISO) teams will need to keep the “human” side of security in focus. Regular recovery drills, phishing simulations, multi-factor authentication, and enterprise-wide spam filters should be part of the plan. From frontline staff to senior executives, everyone should be an active defender against cyber threats.
Distributed Denial Of Service (DDoS)
A DDoS attack disrupts the normal traffic of a targeted network by overwhelming it with fake internet traffic. In this case, attackers use multiple compromised computer systems (often thousands) and malware-infected IoT devices as sources of attack traffic. The attack then creates a "botnet" of these infected systems to generate massive traffic, flooding the target system with requests that it can't handle.
While most DDoS attacks rely on volume-based user datagram protocol (UDP) floods to overwhelm a server’s bandwidth, a few insidious methods target deeper layers of a system. For example, Slowloris and WordPress XML-RPC programs are expanding beyond flood attacks by directly exploiting application vulnerabilities and using multiple IP addresses to stay under the radar. This is often the perfect recipe for a DDoS that can inflict maximum damage with minimal effort.
We saw this play out with AWS when a 2.3 terabits per second (Tbps) DDoS attacked their cloud infrastructure to cause downtime and exfiltrate data in disguise. Thankfully, AWS had strong network monitoring systems, firewalls, and blackhole routing in place to limit the threat area and keep performance from crumbling. Something similarly sinister happened with five VoIP providers across the US, UK, and Canada in 2022. Attackers deployed a DDoS to overwhelm the providers' SIP protocol ports and servers that handle voice call routing. The service outages lasted for more than seven days, with financial ruins running in millions.
The financial and reputational damage from DDoS attacks is substantial. Beyond downtime, organizations face regulatory penalties, SLA breaches, and customer churn. Worse, ransom DDoS (RDoS) attacks—where attackers demand payments to stop attacks—are surging, particularly in finance, healthcare, and cloud services.
AI-driven traffic analysis and anomaly detection, geo-blocking and adaptive rate limiting, inter-cloud scrubbing, and blackhole routing are a few ways to mitigate the risk.
Zero-Day Exploits
A zero-day (or 0-day) exploit is a cyber attack that targets a software vulnerability unknown to the software vendor and users. Every security flaw starts as a zero-day because patches can’t be made until the vendor is aware of the issue. The real risk here is that zero-day attacks hit hard because there’s no patch available to stop them.
Even worse, businesses might not even know they've been compromised and breached until it’s too late. That’s exactly what happened with the MOVEit breach. The Cl0p ransomware gang exploited a zero-day vulnerability in file transfer software, used an SQL injection, and gained access to sensitive data. As of now, over 2,500 organizations and 66.4 million individuals have been impacted by the breach.
Zero-day exploits are essentially the “pandora box” of cybersecurity threats. Once a hacker gets their hands on these vulnerabilities, they can create entry points for other threats to enter and wreak havoc in the system. In 2023 alone, Google’s Threat Analysis Group reported 97 zero-day vulnerabilities were exploited. That means 97 instances where businesses were left wide open to breaches, spyware, malware, and even wipers. And with many businesses still using legacy IT systems without security updates, their numbers seem to climb in 2024’s report as well.
Traditional patch management is no longer enough. Enterprises must transition to a proactive zero-day defense strategy that includes threat intelligence sharing, continuous attack surface monitoring, Virtual patching, and XDR.
Ransomware
Ransomware is a top-tier cybersecurity threat, locking organizations out of their own data until a ransom is paid. In 2023, 72% of enterprises experienced at least one ransomware attack—a number that surged further in 2024, with 59% of businesses already impacted by February.
A typical ransomware attack begins with a phishing email or stolen credentials, which allows the malware to gain access. Once inside, it can disable backup systems, erase shadow copies, and even launch malicious ads or supply chain attacks while holding data hostage. Today, many ransomware attacks are paired with wipers to erase all enterprise data and eliminate any trace that could lead law enforcement to the hackers. This way, all files become inaccessible, even with a decryption key, and halt all business operations for days to come. Not to mention the operational downtime and regulatory compliance that impact customer experience and make brand recall.
A proactive cybersecurity strategy is critical to mitigating ransomware risks. Enterprises must invest in Zero Trust security, immutable, air-gapped backups, and AI-powered threat detection.
SQL Injection
A SQL injection attack happens when an attacker exploits unsanitized input fields to inject malicious SQL commands into a database. Once inside, these commands can cause the database to send data to an external server, even when no output is visible. They can also reveal sensitive information about the database structure. Other times, SQL injections can also trigger second-order attacks, where the injected payload is stored in the database and activated later.
As of now, SQL injection has been used in some major breaches, like FlyCASS Airlines, where a malicious “&” in the username field added fake pilots to the system. The Freepick breach was another attack that compromised the data of 8.3 million users.
These days, SQL injections have shifted beyond traditional websites to API endpoints. With businesses embracing cloud architectures and microservices, APIs often miss out on the rigorous security resilience of full applications, leaving them vulnerable and exposed. Attackers can craft SQL queries that manipulate data flows and even tamper with data or steal valuable backend information. This ease of attack is another reminder of why SQL injections remain a staple in the top 10 OWASP vulnerabilities.
To prevent SQL injection attacks, security teams need to use strong input validation, implement parameterized queries to protect against untrusted inputs, and run security audits to fix vulnerabilities.
