The latest Symantec Internet Security Threat Report (ISTR), Volume 21 (April 2016), reveals an organizational shift by cybercriminals: They are adopting corporate best practices and establishing professional businesses in order to increase the efficiency of their attacks against enterprises and consumers. This new class of professional cybercriminal spans the entire ecosystem of attackers, extending the reach of enterprise and consumer threats and fueling the growth of online crime.
As more and more Malaysians come online for the first time, Malaysia is ranked sixth in the region and 33 globally in terms of social media scams. On the enterprise front, the services industry made up 72.4% percent of spear phishing attacks, making it the most vulnerable industry in Malaysia.
Malaysia in 2015:
- Ransomware Attacks: 5,069 attacks in 2015 (Average 14 attacks per day)
- Social Media Scams: Ranked 6th in APJ. 26,783 social media scams in 2015
- Significant increase in Spam: Global ranking up from 44 in 2014 to 23 in 2015
Advanced professional attack groups are the first to leverage zero-day vulnerabilities, using them for their own advantage or selling them to lower-level criminals on the open market where they are quickly commoditized. In 2015, the number of zero-day vulnerabilities discovered more than doubled to a record-breaking 54, a 125 percent increase from the year before, reaffirming the critical role they play in lucrative targeted attacks. Meanwhile, malware increased at a staggering rate with 430 million new malware variants discovered in 2015. The sheer volume of malware proves that professional cybercriminals are leveraging their vast resources in attempt to overwhelm defenses and enter corporate networks.
Over Half a Billion Personal Information Records Stolen or Lost in 2015
Data breaches continue to impact the enterprise. In fact, large businesses that are targeted for attack will on average be targeted three more times within the year. Additionally, we saw the largest data breach ever publicly reported last year with 191 million records compromised in a single incident. There were also a record-setting total of nine reported mega-breaches. While 429 million identities were exposed, the number of companies that chose not to report the number of records lost jumped by 85 percent. A conservative estimate by Symantec of those unreported breaches pushes the real number of records lost to more than half a billion.
Encryption Now Used as a Cybercriminal Weapon to Hold Companies’ and Individuals’ Critical Data Hostage
Ransomware also continued to evolve in 2015, with the more damaging style of crypto-ransomware attacks growing by 35 percent. This more aggressive crypto-ransomware attack encrypts all of a victim’s digital content and holds it hostage until a ransom is paid. This year, ransomware spread beyond PCs to smartphones, Mac and Linux systems, with attackers increasingly seeking any network-connected device that could be held hostage for profit, indicating that the enterprise is the next target. Malaysia ranks 47th globally, and 12th regionally, in terms of ransomware attacks, with 5069 of attacks in 2015 averaging to 14 attacks per day.
Don’t Call Us, We’ll Call You: Cyber Scammers Now Make You Call Them to Hand Over Your Cash
As people conduct more of their lives online, attackers are increasingly focused on using the intersection of the physical and digital world to their advantage. In 2015, Symantec saw a resurgence of many tried-and-true scams. Cybercriminals revisited fake technical support scams, which saw a 200 percent increase last year. The difference now is that scammers send fake warning messages to devices like smartphones, driving users to attacker-run call centers in order to dupe them into buying useless services.
From the Experts: Security Tips and Tricks
As attackers evolve, there are many steps businesses and consumers can take to protect themselves. As a starting point, Symantec recommends the following best practices:
For Businesses:
- Don’t get caught flat-footed: Use advanced threat and adversary intelligence solutions to help you find indicators of compromise and respond faster to incidents.
- Employ a strong security posture: Implement multi-layered endpoint security, network security, encryption, strong authentication and reputation-based technologies. Partner with a managed security service provider to extend your IT team.
- Prepare for the worst: Incident management ensures your security framework is optimized, measureable and repeatable, and that lessons learned improve your security posture. Consider adding a retainer with a third-party expert to help manage crises.
- Provide ongoing education and training: Establish simulation-based training for all employees as well guidelines and procedures for protecting sensitive data on personal and corporate devices. Regularly assess internal investigation teams—and run practice drills—to ensure you have the skills necessary to effectively combat cyber threats.
For Consumers:
- Use strong passwords: Use strong and unique passwords for your accounts. Change your passwords every three months and never reuse your passwords. Additionally, consider using a password manager to further protect your information.
- Think before you click: Opening the wrong attachment can introduce malware to your system. Never view, open, or copy email attachments unless you are expecting the email and trust the sender.
- Protect yourself: An ounce of protection is worth a pound of cure. Use an internet security solution that includes antivirus, firewalls, browser protection and proven protection from online threats.
- Be wary of scareware tactics: Versions of software that claim to be free, cracked or pirated can expose you to malware. Social engineering and ransomware attacks will attempt to trick you into thinking your computer is infected and get you to buy useless software or pay money directly to have it removed.
- Safeguard your personal data: The information you share online puts you at risk for social engineered attacks. Limit the amount of personal information you share on social networks and online, including login information, birth dates and pet names.
