Cybercriminals Changing Their Tactics to Deceive Companies and Digitally Extort Consumers
Symantec report reveals almost nine in ten small and medium businesses were targeted in 2014 in Thailand
Bangkok, Thailand – May 14, 2015 – In today’s hyper-connected world, it is no longer a question of if you will be attacked—but when. Symantec’s (Nasdaq: SYMC) Internet Security Threat Report (ISTR), Volume 20, exposes a tactical shift by cyberattackers: they are infiltrating networks and evading detection by hijacking the infrastructure of major corporations and using it against them.
“We are seeing a dramatic shift in the mode of attacks. Attackers have stepped up their game by tricking companies into infecting themselves through Trojanised software updates, hiding their malware inside software updates of programs used by target organizations. This enables cybercriminals to gain full access to corporate networks without the need to even make any forced entry,” said Nigel Tan, Country Director, Malaysia & Thailand, Symantec.
Tan added, “Almost no company, whether large of small, is immune from targeted attacks. In Thailand, almost nine in ten small and medium businesses with less than 500 employees were targeted with spear-phishing attacks. In view of the growing sophistication of these attacks, good IT security is essential and broad cybersecurity practices should be the norm.”
Attackers Succeed With Speed and Precision
In a record-setting year for zero-day vulnerabilities, Symantec research reveals that it took software companies an average of 59 days to create and roll out patches—up from only four days in 2013. Attackers took advantage of the delay and, in the case of Heartbleed, leapt to exploit the vulnerability within four hours. There were 24 total zero-day vulnerabilities discovered in 2014, leaving an open playing field for attackers to exploit known security gaps before they were patched.
Meanwhile, advanced attackers continued to breach networks with highly-targeted spear-phishing attacks, which increased a total of eight percent in 2014. What makes last year particularly interesting is the precision of these attacks, which used 20 percent fewer emails to successfully reach their targets and incorporated more drive-by malware downloads and other web-based exploits.
Additionally, Symantec observed attackers:
- Using stolen email accounts from one corporate victim to spear-phish other victims higher up the food chain;
- Taking advantage of companies’ management tools and procedures to move stolen IP around the corporate network before exfiltration;
- Building custom attack software inside the network of their victims to further disguise their activities.
Digital Extortion on the Rise
Email remains a significant attack vector for cybercriminals, but they continue to experiment with new attack methods across mobile devices and social networks to reach more people, with less effort.
“Instead of doing the dirty work themselves, cybercriminals are taking advantage of unwitting users to proliferate their scams,” added Tan. “For 2014, Thailand ranked 8th in the Asia Pacific and Japan region for the number of social media scams. Interestingly, the majority of these scams, were shared manually as attackers took advantage of people’s willingness to trust content shared by their friends.”
While social media scams can provide cybercriminals with quick cash, some rely on more lucrative and aggressive attack methods like ransomware, which rose 113 percent last year. Notably, there were 45 times more victims of crypto-ransomware attacks than in 2013. Instead of pretending to be law enforcement seeking a fine for stolen content, as we’ve seen with traditional ransomware, the more vicious crypto-ransomware attack style holds a victim’s files, photos and other digital content hostage without masking the attacker’s intention. Thailand recorded an estimated 2,504 ransomware attacks last year, 12th highest in the region.
Secure It, Don’t Lose It!
As attackers persist and evolve, there are many steps businesses and consumers can take to protect themselves. As a starting point, Symantec recommends the following best practices:
- Don’t get caught flat-footed: Use advanced threat 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 guidelines and company policies 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.
- Use strong passwords: This cannot be emphasized enough. Use strong and unique passwords for your accounts and devices, and update them on a regular basis—ideally every three months. Never use the same password for multiple accounts.
- Be cautious on social media: Don’t click links in unsolicited email or social media messages, particularly from unknown sources. Scammers know people are more likely to click on links from their friends, so they compromise accounts to send malicious links to the account owner’s contacts.
- Know what you’re sharing: When installing a network-connected device, such as a home router or thermostat, or downloading a new app, review the permissions to see what data you’re giving up. Disable remote access when not needed.
