Hackers shift focus to zero-day attacks, challenging traditional cybersecurity defenses with new tactics.
Emerging Face of Cyber Threats: Zero-Day ExploitsRecently, Symantec's threat intelligence team has almost entirely unraveled a possible pivot in the modus operandi used by hackers of ransomware. The emergence is that the perpetrators are now progressively resorting to zero-day vulnerabilities when previously they highly relied on botnets - the networks of malware-infected computers. That marks a marked shift in the cyber threat landscape and will mean organizations have to change tack rapidly.
A study by Palo Alto Networks found that on average, a zero-day vulnerability can go undetected for 312 days. This long period allows attackers to exploit these vulnerabilities extensively before they are discovered and patched. The IBM Cost of a Data Breach Report 2021 highlighted that the average cost of a data breach rose to $4.24 million per incident, the highest in the 17-year history of the report. The use of sophisticated attack vectors like zero-day exploits contributes to the increased impact and cost of these breaches.
Ransomware gangs have traditionally utilized botnets to launch their attacks. However, with international pressure against these networks gaining momentum amongst police units, such attackers are now looking elsewhere - towards zero-day vulnerabilities. These defects remain unknown to software developers until they come under exploitation and offer a stealthier avenue for the attack of hacking. Attacks using zero-day vulnerabilities can be more damaging than those using known vulnerabilities. They can remain undetected for longer periods, allowing attackers to infiltrate systems deeply and cause extensive damage before being discovered. Exploiting these vulnerabilities, clever attackers bypass traditional security measures, leaving companies scrambling to patch systems only after the damage has begun.
The success of law enforcement in dismantling botnets has inadvertently pushed hackers towards these more sophisticated tactics. As Vikram Thakur, technical director at Symantec, notes, "The motivation for [hackers] to find more vulnerabilities in public-facing infrastructure is massive." This pivot to exploiting zero-days in widely-used software like Citrix, MOVEit, Ivanti, and Microsoft Exchange is a direct response to the tightening noose around botnet operations. A report by Europol's European Cybercrime Centre (EC3) noted a shift in ransomware tactics, moving away from mass distribution methods (often via botnets) to more targeted attacks, which may include the use of zero-day exploits.
Zero-day vulnerabilities pose a unique challenge. Unlike botnets, where malware is often quickly identified and neutralized, zero-days allow hackers to operate undetected, often leaving organizations vulnerable before they're even aware of the breach. Thakur highlights this stealth aspect, emphasizing the need for more proactive defense strategies. CodeLock advises a strategic shift in defense tactics. Organizations are encouraged to focus less on the specific ransomware strain and more on understanding and mitigating the tools, tactics, and procedures employed by hackers. This approach requires a thorough audit of administrative tools and security protocols to ensure they are both necessary and secure.
