Black Arrow Cyber Threat Briefing 31 March 2023
Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.
Top Cyber Stories of the Last Week
Phishing Emails Up a Whopping 569% in 2022
The volume of phishing emails sent in 2022 spiked by a jaw-dropping 569% according to a new report. Based on data from 35 million users, the report details the astronomical rise of email phishing as a tactic among threat actors in 2022. Key findings from the report include the number of credential phishing emails sent spiked by 478% and, for the eighth consecutive year, business email compromise (BEC) ranked as the top cyber crime.

The End User Password Mistakes Putting Your Organisation at Risk
Businesses rely on their end users, but those same users often don't follow the best security practices. Without the right password security policies, a single end user password mistake can be a costly breach of your organisation's defences. End users want to do their work quickly and efficiently, but sharing, reusing and weak passwords can put your organisation at risk so having the right policies in place is essential for security.
Millions of Penetration Tests Show Companies’ Security Postures are Getting Worse
The risk score for the average company worsened in the past year as companies fail to adapt to data exfiltration techniques and adequately protect web applications. Companies' effective data-exfiltration risk increased to 44 out of 100 (with 100 indicating the riskiest posture) in 2022, from an average score of 30 in the previous year, indicating that the overall risk of data being compromised has increased. That's according to rankings by Cymulate, who crunched data on 1.7 million hours of offensive cyber security testing. The research noted that while many companies are improving the adoption of strict network and group policies, attackers are adapting to sidestep such protections. They also found that four of the top-10 CVEs (known vulnerabilities) identified in customer environments were more than two years old.

71% of Employees Keep Work Passwords on Personal Devices
71% of employees store sensitive work passwords on their personal phones, and 66% use their personal texting apps for work, according to a new mobile bring your own device (BYOD) security report this week, with the report also suggesting 95% of security leaders are increasingly concerned about phishing attacks via private messaging apps. With the widespread use of personal mobile devices in the workplace, it is increasingly difficult for employers to ensure the security of sensitive information. The use of personal devices and personal apps was the direct cause of many high-profile corporate breaches and this is a trend that will surely continue, as employees often use corporate and personal devices for work, effectively doubling the attack surface for cyber criminals as threat actors know there are fewer security controls on personal mobile devices than on corporate ones.

Cyber Frontlines in Russia-Ukraine War Move to Eastern and Northern Europe
More than a year into the war in Ukraine, hackers have extended the cyber battleground to Eastern and Northern Europe with the number of incidents in those geographies spiking noticeably. A new report shows that cyber warfare inside the conflict has “clearly moved on” from the beginnings of the war. Over the last 12 months, the research reports that the majority of incidents only affecting Ukraine in the first quarter of 2022 (50.4%) sank to 28.6% in the third period. But European Union countries have seen a spike in incidents related to the war in the past six months from 9.8% to 46.5%. Indeed, the number of attacks on EU countries in the third quarter of 2022 totalled just slightly less than those in the Ukraine. And, in the first quarter of this year, more than 80% of incidents occurred inside the European Union. Cyber is now a crucial weapon in the arsenal of new instruments of war, alongside disinformation, manipulation of public opinion, economic warfare, sabotage and guerrilla tactics. With the lateralisation of the conflict from Ukraine to the rest of Europe, Western Europe should be wary of possible attacks on critical infrastructure in the short term if the conflict continues to accelerate.
Security Flaws Cost Fifth of Executives New Business
Boards continue to under-appreciate the value of cyber security to the business, despite acknowledging its critical role in winning new business and talent, according to Trend Micro. The security giant polled 2,718 business decision makers globally to compile its Risky Rewards study and it found that half (51%) believe cyber security is a necessary cost but not a revenue contributor. 48% argue that its value is limited to threat prevention and two-fifths (38%) see security as a barrier rather than a business enabler. That’s despite a fifth (19%) acknowledging that poor security posture has already impacted their ability to win new business, and 57% thinking there is a strong connection between cyber and client acquisition.

Companies Struggle to Build and Run Effective Programs to Protect Data from Insider Threats
Insider risk is emerging as one of the most challenging threats for organisations to detect, mitigate and manage, Code42 Software said in its annual Data Exposure Report for 2023. To compile data for the study they surveyed some 700 cyber security leaders, managers and practitioners and whilst more than 72% of companies indicated they have an insider risk management (IRM) program in place, the same companies experienced a year-over-year increase in data loss incidents of 32%. 71% of respondees expect data loss from insider events to increase in the next 12 months. Insider incidents are costing organisations $16 million per incident on average, and chief information security officers (CISOs) say that insider risks are the most challenging type of threat to detect. Data loss from insiders is not a new problem but it has become more complex with workforce turnover and cloud adoption.
Only 10% of Workers Remember All Their Cyber Security Training
New research has found that only 10% of workers remember all their cyber security training. Furthermore, only half of employees are undergoing regular training, and a quarter aren’t receiving any training at all. Organisations should look to carry out effective and regular training that is tailored to their employees to increase the chance of training content being retained, with a programme of ongoing continual reinforcement.
Silence Gets You Nowhere in a Data Breach
In cyber security, the phrase “what they don’t know won’t hurt them” is not only wrong, it’s dangerous. Despite this, it’s a motto that remains in many organisations’ PR playbooks, as demonstrated by the recent LastPass and Fortra data breaches. Smaller companies, too, are employing a silent-treatment approach to data breaches, and cyber attacks are now a fact of doing business with almost half of US organisations having suffered a cyber attack in 2022. Attackers are increasingly targeting smaller businesses due to the fact they are seen as easier targets than large companies.

Just 1% of Cloud Permissions are Actively Used
According to Microsoft, a surge in workload identities, super admins and “over-permissioning” is driving the increase in cyber risk for organisations. Just 1% of users are using the permissions granted to them for day-to-day work. Worryingly, this leaves a significant number of unnecessary permissions which could be used by an attacker to elevate their privileges.

Dangerous Misconceptions About Emerging Cyber Threats
Organisations are leaving common attack paths exposed in their quest to combat emergent threats, according to a new report that delves into the efficacy of different security controls, the most concerning threats as tested by organisations worldwide, and top cyber security best practices for 2023. One of the key findings of the report is that many organisations are actively testing against threats seen in the news, likely from pressure to report on their exposure risk to emergent threats, and whilst this is good, it should not take away from assessing threats and exposures that are more likely actively targeting the business.

‘Grim’ Criminal Abuse of ChatGPT is Coming, Europol Warns
Europol has warned that criminals are set to take advantage of artificial intelligence to commit fraud and other crimes. Europol highlighted that ChatGPT could be used to speed up criminal research, impersonate speech styles for phishing and write code. Furthermore, despite ChatGPT having safeguards, Europol note that these can be circumvented.
