EN： The structure 'spend + [amount of money/time] + [frequency] + to + infinitive' (or 'spend + time/money + doing') is used to express the cost or investment needed to achieve an objective. In news headlines, the full infinitive 'to investigate' explicitly denotes purpose ('in order to investigate').

EN： News headlines commonly use the simple present tense ('Spends') to report recent or ongoing events to create a sense of immediacy and drama, even if the action has already started or happened in the past.
Tech giant launches new satellite to monitor climate change.
EN： In modern tech journalism, headlines use title casing (capitalizing major words) and present tense verbs to grab attention. Unauthorized automated access by AI crawlers or bots is often referred to plainly as 'hacking' in headlines to convey the serious nature of a security breach.
EN： The sentence uses the present perfect tense ('has announced') to indicate a recent action that has current news relevance, followed by a 'that'-noun clause functioning as the direct object of the verb.

EN： The verb 'cost' is used in the present continuous tense ('is costing') to emphasize an ongoing, active expense that continues day by day, modified by the comparative phrase 'more than'.
The ongoing repair is costing a lot of money.
EN： In cybersecurity and corporate PR, terms like 'data breach incidents' are carefully chosen formal vocabulary used to describe unauthorized access to systems, emphasizing an objective and technical review process.
EN： The verb 'access' is transitive in English and is followed directly by its direct object without a preposition (e.g., avoid saying 'access to a website').
Unauthorized users cannot access the database.
EN： The prepositional phrase 'without + noun/gerund' functions as an adverbial of manner, indicating that an action is performed lacking a specific condition or permission.

EN： A 'petabyte' (PB) equals 1,024 terabytes or roughly one million gigabytes. In modern tech and cybersecurity contexts, auditing petabyte-scale data requires specialized AI infrastructure, highlighting that this is not merely a manual file inspection but a massive computational effort.
EN： The adverb 'roughly' is used before numbers, amounts, or quantities to mean 'approximately' or 'about'. It functions as a degree/quantity modifier.
The trip will take roughly three hours by train.
EN： Large number expressions followed by 'of': Countable data units (like gigabytes) can be quantified with large numerical compounds (50 million gigabytes) followed by the preposition 'of' and an uncountable noun (information) to specify what the quantity consists of.
The hard drive contains thousands of gigabytes of photos.
EN： In technology journalism, journalists often convert complex and unfamiliar storage units (such as petabytes) into more recognizable consumer terms like 'gigabytes' or human-scale analogies (e.g., millions of years of reading) to help general readers grasp the massive scale of a cybersecurity breach or dataset.
EN： Second Conditional (Unreal Present/Future): Used to talk about hypothetical, unlikely, or impossible situations in the present or future. The structure is 'if + past simple (were/did), would + base verb'. The subjunctive form 'were' is conventionally used for all subjects including singular ones.
If I had more free time, I would learn how to code.
EN： 'It takes [someone] [time] to [do something]': A common pattern used to express the amount of time required for someone to complete an action. In hypothetical contexts, it changes to 'it would take...'.

EN： The adverbial phrase 'so far' means 'up until now'. It is commonly used with the present perfect tense to indicate that a situation is ongoing and the number or status may change in the future.

EN： The past perfect tense ('had accessed') is used here to indicate an action that happened before another past event (the main verb 'revealed'). Since the accessing took place in June before the Friday evening announcement, 'had + past participle' is required.

EN： The verb 'reveal' takes a noun clause introduced by the conjunction 'that' as its direct object ('revealed that...'). This pattern is commonly used in reporting verbs to introduce factual information or statements.

EN： Parallel 'that' clauses: When a reporting verb (like 'warn', 'say', or 'state') takes multiple noun clauses as objects, each clause is typically introduced by 'that' and joined by coordinating conjunctions such as 'and'. Keeping the second 'that' helps maintain clarity in formal and news contexts.
The manager explained that the system was down and that technicians were fixing it.
EN： Passive voice with modal verbs: The structure 'modal verb + be + past participle' (e.g., 'may be contacted') is used when the focus is on the recipient of the action rather than the doer, or when the agent is unknown or implied.
All participants will be notified before Friday.
EN： In cybersecurity and corporate communication, phrasing like 'investigation is still ongoing' and 'organizations may be contacted' is standard legal-cautious language.

EN： In the modern tech sector, publishing post-mortems, updates, and breach disclosures via an official 'blog post' is the standard industry practice for corporate transparency, often replacing traditional press releases.
EN： The relative pronoun 'which' introduces a restrictive relative clause modifying the noun 'activity'. It acts as the subject of the passive verb phrase inside the clause.

EN： The present perfect passive ('has not been discovered') combined with 'yet' indicates an action that has not occurred up to the present moment, but is anticipated.
